UDAIPUR: Capturing rainwater is the most sustainable solution to deal with water scarcity in Rajasthan and specially when the technique is the traditional wisdom of the desert state.
According to Central Ground Water Board (CGWB), out of 243 blocks in Rajasthan, 196 fall in the critical zone. This means that in these regions, the annual withdrawal of water from underground is more than what falls as rain. There is growing imbalance between demand and supply of water in the state.

As per international standards, availability of water below 500 cubic meter is considered as absolute water scarcity. The annual per capita availability of water in the state is expected to go down to 439 m3 by 2050 which was 840 m3 in 2001 and against the national average of 1,140 m3 by 2050. Wells for India, (WI) a UK-based NGO which have been working for three decades for the water cause, has helped people to deal with water scarcity through rainwater capturing techniques. WI with its partner GRAVIS, another NGO helped construction and repair of 895 taankas in Pabupura cluster in the Phalodi block of Jodhpur district which has ensured water security to 900 families. These Taankas have of 21,000 litre capacity.

Now 900 families have water source at their doorstep for a period varying from 9 to 12 months. “The intervention has helped women in saving time, money and labour. Their working hours have reduced from 18 to 15 hours and now they can relax for around nine hours a day as compared six hours in the past. The increased water availability for a longer duration has reduced physical workload, mental stress and health related problems of women,” says OP Sharma, country director, WI.

Tanka beneficiaries started to take bath and wash clothes more frequently. The water use in washing clothes and taking bath has increased by more than 4 times, whereas the water used by animals has increased by 2.5 times. Moreover, daily cleaning of utensils and water storage pots has substantially increased. Above 70% of the tanka families have started using alum/chlorine tablets to purify their drinking water, whereas more than 80% of the families have started using ladle to take water from the pot. Last but not least, expenditure incurred on water for drinking and domestic purpose including the water for animals reduced from 2 to 3 times.

Similarly in Hilly regions of Bhinder block of Udaipur seen the significant impacton increase in irrigated area on account of mainly ground water / well rechargedue to construction of small water harvesting works such as loose stone checkdams, masonry dams etc. Prior to construction of these structures the totalirrigated area under the command of these 39 existing wells (i.e in 2004) was only 23 hectare, which has now been (up to Rabi 2016 ) increased to 80 hectare. Irrigated area is showing the significant impact of these small water harvesting works on increasing the availability of water.

Five environmental entrepreneurs making money sustainably

An underlying theme of sustainable businesses is innovation – through either a product, service or a combination of both. Here are five environmental entrepreneurs saving the environment and promoting sustainability through their startups.

Many entrepreneurs today are setting up sustainable businesses that solve environmental problems and still make money because that’s the only way to keep any enterprise going.

An underlying theme of sustainable businesses is innovation – through either a product or a service or a combination of both. Environmental entrepreneurs solve the pressing problem of saving the environment and aiding ecological balance.

Here are five entrepreneurs who are contributing immensely to the cause of the environment through their unique products:

1. Nitin Sharma, Go Waterless, Pune

Water scarcity left Nitin’s family car wash business high and dry in 2016. After the problem continued well into 2017, Nitin began to research products that could wash cars without water.

Finally, in 2019, he developed eco-friendly high-lubricity sprays that clean car interiors and exteriors without water. Go Waterless has been profitable since its inception in 2019 and is present in 22 states.

More importantly, it is saving 12 lakh liters of water daily and earning Rs 2.5 crore in annual revenues.

2. Ashvin Patil and Chaitanya Korgaonkar, Biofuels Junction, Mumbai

Ashvin is an MBA and engineer who quit his job as an equity market analyst to set up Biofuels with his friend Chaitanya.

The duo started Biofuels in 2018 with the dual aim of solving farmers’ problem of agri waste disposal and providing clean fuel to enterprises. Most farmers, after harvest, burn residues like rice stubble, cotton stalks, and coconut husks, causing pollution.

Biofuels procures agri waste from farmers and it is then processed into solid biofuels at the nearest manufacturing facility in the startup’s network. The company’s field staff monitors the quality and consistency of biofuels, which replace coal, diesel and furnace oil at industrial plants, reducing the burden on non-renewable resources.

The sustainable startup works with 25,000 farmers and over 100 top companies. In just four years of launch, it is clocking Rs67 crore in annual revenues.

3. Amit Doshi, NeeRain, Ahmedabad

When Amit Doshi was in class four, he and his brother would accompany their mother to fill water from a tap near their house in Kalol, about 35km from Ahmedabad in Gujarat. The area’s borewells had dried up and the municipality supplied water every three days.

Growing up with water scarcity instilled in Amit a sense of purpose – to save every drop of water. One way to do it was through rainwater harvesting by collecting and storing rainwater that runs off from rooftops, roads, grounds, etc.

After a year of research and development, he designed an instrument to help people collect rainwater, which could be used to recharge borewells or stored, and named it NeeRain Rainwater Filter. This small filter unit with dimensions of 1x1x1.5 feet uses an engineering material called ABS (Acrylonitrile Butadiene Styrene), and it was patented in 2018. Amit’s startup earns Rs 2 crore in revenues annually and is growing rapidly.

4. Vinayakumar Balakrishnan: Thooshan, Kochi

Having spent a large part of his life working in leadership roles in the banking and insurance sector, Vinayakumar decided to return from Dubai to India in 2013 and began research on food waste that could be used to make biodegradable plates.

He approached the Council of Scientific & Industrial Research (CSIR)’s National Institute for Interdisciplinary Science and Technology (NIIST) in Thiruvananthapuram and funded the research on making biodegradable food plates from rice bran. Once the technology was in place, he set up a fully integrated robotic plant in Kochi to make biodegradable cutlery and Thooshan went live in 2021.

According to estimates, producing just one pound of plastic cutlery can take up to 78 liters of water and release 2.5 lbs (1.1 kg) of carbon dioxide. This plastic is difficult to recycle and ends up choking animals and polluting water bodies and soil.

Thooshan cutlery can be decomposed into organic manure or can be used as cattle feed, fish feed, or poultry feed. The startup is sustainable and environment-friendly.

5. Bhavini Parikh, Bunko Junko, Mumbai

In 2016, while working on her garment manufacturing business, Bhavini came across research that textile waste is the third largest source of municipal solid waste in India. With landfills having a limited capacity to take on the load, she decided to minimize fabric waste at her level.

“I realized I was also hurting the environment by being part of the fashion industry. So I thought of up-cycling fabric scraps produced in my garment manufacturing unit,” she says.

Today, her ethical fashion brand Bunko Junko turns textile scrap into stylish clothing, home furnishings, and accessories. Since 2018, it has saved 38 tonnes of fabric from going to landfills and empowered thousands of women. And her profitable operations clock Rs. 40 lakh in revenues annually.

India’s water crisis: The clock is ticking

We need to promote a decentralised approach, with a key focus on water conservation, source sustainability, storage and reuse wherever possibles

India is facing one of its major and most serious water crisis.

After two consecutive years of weak monsoons, 330 million people — a quarter of the country’s population — are affected by a severe drought. With nearly 50 per cent of India grappling with drought-like conditions, the situation has been particularly grim this year in western and southern states that received below average rainfall.

According to the Composite Water Management Index (CWMI) report released by the Niti Aayog in 2018, 21 major cities (Delhi, Bengaluru, Chennai, Hyderabad and others) are racing to reach zero groundwater levels by 2020, affecting access for 100 million people.

However, 12 per cent of India’s population is already living the ‘Day Zero’ scenario, thanks to excessive groundwater pumping, an inefficient and wasteful water management system and years of deficient rains. The CWMI report also states that by 2030, the country’s water demand is projected to be twice the available supply, implying severe water scarcity for hundreds of millions of people and an eventual six per cent loss in the country’s GDP.

The Union government recently formed a new Jal Shakti (water) ministry, which aims at tackling water issues with a holistic and integrated perspective on the subject. The ministry has announced an ambitious plan to provide piped water connections to every household in India by 2024.

The ministry has set a tough target at a time when hundreds of millions don’t have access to clean water. Aiming at laying huge pipeline networks for water supply means that yet again, we are giving more preference to infrastructure. Also, the moot questions are: what will happen if there is no water to supply? What will happen to all the wastewater that gets generated?

This indicates that there is a clear disconnect between water, society and economy. Currently, we are interested in laying large networks, constructing huge storage dams, fetching water from 150 kilometres and above, which involves a huge carbon footprint.

We are valuing land more than water, neglecting our local water bodies, which have either gone dry or encroached. Also, in many Indian cities, water is not properly distributed. Some areas of mega cities like Delhi and Mumbai are privileged to get more that than the standard municipal water norm of 150 litres per capita per day (lpcd) while other areas get 40-50 lpcd.

Aggravating the problem is that the water being supplied currently is of drinking water standards.

The World Health Organization (WHO) states that an individual requires around 25 litres of water daily for meeting his/her basic hygiene and food needs. The rest is used for non-potable purposes like mopping and cleaning. This indicates that for most of the non-potable uses, a quality lower than drinking water is required. Thus, for economic efficiency and environmental sustainability, water must be treated and supplied according to usage.

To top this, are issues of leakage losses, water pricing and metering of water. Lack of proper maintenance of existing infrastructure causes further losses of almost 40 per cent of piped water in urban areas.

The road ahead

Looking at the current situation, there is a need for a paradigm shift. We urgently require a transition from this ‘supply-and-supply-more water’ provision to measures which lead towards improving water use efficiency, reducing leakages, recharging/restoring local waterbodies as well as applying for higher tariffs and ownership by various stakeholders.

A recovery-based closed loop system is the need of the hour.

It is time to go back and start using our traditional practice of rainwater harvesting — catching water where it falls. Presently, India captures only eight per cent of its annual rainfall, among the lowest in the world.

Another aspect is the treatment and reuse of wastewater. About 80 per cent of the water that reaches households, leaves as waste and pollutes our waterbodies and environment. There is a huge potential in reusing and recycling this treated wastewater at least for non-potable purposes, which is cost effective.

All this leads to the fact that we need to promote a decentralised approach, with a key focus on water conservation, source sustainability, storage and reuse wherever possible.

It is important to understand that managing the water situation is not the job of only engineers but all stakeholders including hydrogeologists, economists, planners and most importantly, communities themselves.

Emphasis on behavioural change is not getting enough attention because it is nuanced and complex. But locals/citizens/ communities have a huge part to play. By keeping in check our own usage and actions, we can contribute.

As for our decision-makers, they need to re-think: Are we being sold dreams or realities?

Catch the rain, fix water crisis: How Odisha leads by example

Photo courtesy:  Down to earth

Odisha has deveoped 12,000 rainwater harvesting structures to facilitate water conservation and ground water recharge in 2,035 wards

Water is a source of life for all of us and helps our natural environment thrive. In this era of climate change, the unavailability of water is going to hit the developing world the most. Maintaining a balance between natural and human-made components is the only way to survive.

Odisha has been going through water scarcity, drought, floods, groundwater depletion and much more. In Odisha, the groundwater extraction has increased to 42 per cent, from 30 per cent in four years — between 2013 and 2017.

There is a massive increase in annual groundwater extraction. But there is a reduction in annual groundwater recharge and a considerable depletion in the annual extractable groundwater resources.

According to the Central Ground Water Board (CGWB), Odisha’s groundwater volume was assessed at 16.69 billion cubic metres in 2009. This has dropped to 15.57 billion cubic metres in 2017, leading to a loss of 1.12 billion cubic metres (6.71 per cent) of groundwater.

The CGWB has clearly indicated that the groundwater of 24 out of 30 districts in Odisha is depleting. The groundwater aquifers in many regions of Odisha have already gone dry.

In 2019, out of 30 districts in Odisha, 29 had received deficient rainfall, while only Koraput district recorded one per cent surplus precipitation. In nine districts, rain deficit has been measured to be over 40 per cent.

Balasore was the worst-hit, with 54 per cent deficit rainfall. As many as 26 districts had a deficit above 19 per cent. This situation is worsening.

Some 1,093 million litres of drinking water are supplied to urban areas in the state against the daily demand of 1,088 million litres. This is leading to immense pressure on the state’s water resources.

The groundwater level in the greater Bhubaneswar area (Bhubaneswar city and outskirts / peripheries) has shrunk by about 10 metres and more since 2006 and water consumption has doubled in the last 10 years. This has been due to large-scale extraction of groundwater to cater to the daily demand of Bhubaneswar.

The development blueprint for the state is heavily dependent on groundwater both for water supply to its citizens and irrigation to the drought-prone areas of the Kalahandi-Bolangir-Koraput (KBK) region.

Rainwater harvesting

To combat these issues, the state of Odisha with the Centre for Science and Environment as its knowledge partner, has successfully implemented an intensive campaign of rainwater harvesting.

It has come up with 12,000 Rainwater Harvesting Structures (RWHS) to facilitate water conservation and groundwater recharge in 2,035 wards of 114 urban local bodies. All this has happened in less than three months ie before the onset of the southwest monsoon.

Rainwater harvesting is collecting the run-off from a structure or other impervious surfaces, in order to store it for later use. This process is used to conserve rainwater that runs off from rooftops, parks, roads and open grounds by collecting, storing, conveying and purifying it.

The state had selected sites to have RWHS to address the statewide campaign Catch the Rain: Where it Falls and When it Falls. This has been completed under the Mukhyamantri Karma Tatpara Abhiyan (MUKTA), an urban wage employment scheme for migrant workers.

Odisha’s annual rainfall varies from 1,200-1,800 millimetres but its spatial distribution is uneven and erratic. Eighty per cent of this rainfall occurs from June to September.

The state receives 76 per cent of rainfall between mid-June and mid-September and receives the remaining 24 per cent throughout the year. It has been estimated that out of 230.76 billion cubic metres of rainfall in a year, 80 per cent flows to the sea as surface runoff as adequate storage has not been developed.

During the monsoon, there are very wet days and also long dry spells. In some years, both floods and droughts occur. Not just that, the sub-surface storages are getting emptied, leading to thinner flows in rivers and streams, causing further capacity decrease in groundwater recharge.

Considering the uneven rainfall pattern, the only way to use the surplus rains received is by storing it. So, the state government has come up with such an initiative to build the RWHS in the 114 urban local bodies to minimise the surface runoff and maximise ground water recharge.

The state government wanted to develop a mechanism that would be cost-effective, need simple technology to operate and would require least maintenance.

Fortunately, the experts were successful in their approach. The RWHS type is Pit and Burrow, which costs Rs 35,000 per unit, involves no complex technologies and requires less maintenance. Also, it can be completed in a period of just 7-10 days.

The Government of Odisha aims to conserve both the rooftop runoff of government and private-aided institutions and storm water runoff from parks, playgrounds, open space, vacant lands and roads.

The spacing and number of recharge pits will be based on the porosity and permeability of the soil below 1.8 metres, annual average rainfall, intensity and duration of rainfall in that particular region.

For average conditions, one recharge pit of 1.2 metres diameter and 1.8 metres depth, with a leading channel of 15 metres is adequate for 250 square metres of catchment area.

The recharge mechanism is also simple. Partial recharge of rainwater from the catchment happens through the loading channel. Surplus rainwater received from the loading channel and storm water from the area surrounding the pit is recharged through filled media.

The sand layer acts as conventional surface water filter media. To support it, broken granite chips are provided underneath the sand layer. The sand layer filters out and retains the suspended solids, thereby providing a base for the grey / black blanket formed over the sand due to filtering of clay, silt and colloidal particles.

The filter media in the leading channel and recharge pits act like porous membranes that allow the partially filtered rainwater to reach the soil media interface.

The underneath soil layer acts as natural filter which facilitates micro filtration of rainwater before it reaches the groundwater table. Over a period, the top layer turns grey or black which reduces the recharge efficiency.

So, the top layered sand can be replaced periodically with new sand layers. The removed layer is rich in organic nutrient which can be utilised for filling the plantation sites in the park and open space area.

The Government of Odisha recommended mandatory construction of 5 RWHS per ward in a notified area council (NAC), 10 RWHS per ward in a municipality and 20 RWHS per ward in a municipal corporation of the 114 urban local bodies.

Daspalla, one of the NACs in Odisha, has completed 80 RWHS with 138 pits in 16 wards of the urban local body. According to Sasmita Pradhan, programme coordinator of MUKTA in Daspalla, 40 self-help groups (Mission Shakti Groups) and 2,898 people have been employed for this initiative as one pit requires three people to build.

To strengthen the transparency and accountability, Odisha’s housing and urban development department has made it mandatory for the sites to be geo-tagged and directed the district collectors to monitor the progress accordingly.

Rainwater harvesting is a go to solution for the emerging water crisis. Like Odisha, it is high time for us to take necessary steps to recharge the groundwater thereby enabling the planet to provide maximum resources for our coming generations.

Roofs, rain and life: How to incentivize and implement rainwater harvesting

Co-author: Carmen Anthonj , Assistant Professor GeoHealth, Geo-Information Science and Earth Observation (ITC) of the University of Twente

While rainwater harvesting can result in numerous benefits for consumers and the water sector overall (read our previous blog here), it’s not always clear how to effectively promote and increase the prevalence of this practice.

RWH systems can be built relatively easily with local skills and resources, using simple and easy-to-maintain technologies that are inexpensive once installed. RWH systems can be modular in nature by allowing expansion, reconfiguration or relocation, and can easily be retrofitted to an existing structure or built during new construction.  However, despite the many benefits, households often find it difficult to implement rainwater harvesting.  The initial installation cost of RWH systems on residential housing is relatively high and a common barrier to adoptioni. Moreover, while there are legal, social and environmental barriers as well, recent experiences have documented means of overcoming those barriers and reinforcing water management practicesii.

There are many ways to encourage rainwater harvesting and improve its implementation, within which governments can play a strong role. The use of government subsidies as incentives can encourage the installation of RWH systems and increase the number of users, particularly among poorer households. The regulatory frameworks are essential for the effective design of these incentives, like in Brazil. In Germany, the promotion (by grants and subsidies) of RWH at the local government level resulted in equipping almost one third of new buildings built with rainwater collection systems. The Government of Indiaiii, for example, provides financial assistance for the installation of RWH systems. The Surat Municipal Corporation has made RWH mandatory for new buildings with a plot size of >4,000 m² and provides up to a 50% (up to Rs. 2,000) subsidy to citizens to encourage rainwater recharging. In Gwalior and Jabalpur, a 6% rebate in property tax in the year of completion of RWH construction is provided to the building owner as an incentive (CSE, 2019).

Promoting rainwater use through housing regulations that stipulate that all newly built buildings and structures must include rainwater roof catchments is common in Taiwan, Texas and Brazil. Although laws and other governmental policies are the key driver for the implementation of RWH, overall, robust policies to systematically promote the installation of RHW are often lacking or scattered. In Brazil for example, RWH is barely covered in legislation at the federal level, but more common at the local level. In absence of a national policy regulating RWH, some state laws and mainly municipal regulations have taken the task of covering this legislative gap, as local authorities may be more aware of specific problems for the region and thus implement specific legislation for the municipality. Large numbers of different laws and regulations at different scales complicate the process of implementation. Besides, the scattered legislation does not cover all aspects of RWH: the main goal of regulations is usually encouraging the installation of RWH systems, but incentives for the implementation are rare, and no legislation exists that addresses treatment to improve the quality of rainwater (da Costa Pacheco et al., 2017). Besides, coordination between state and non-state stakeholders in RWH, and residents lacking awareness or knowledge of policies, are common challenges (Bui Thi Thuy et al., 2019; Matto & Jainer, 2019).

A Prospective Vision for RWH

The strategic management of rainwater can reduce disaster risk for communities faced with water scarcity, droughts or flood risks. Access to clean water is essential during the pandemic for handwashing, hygiene and preventing the spread of COVID-19. The scalability of RWH must ensure that water is provided and available when needed free of contamination, and as a resilience option in remote rural areas that are hit hard by climate change and rainfall variability. All the efforts to bring these solutions to increase water availability must carefully consider cost-effectiveness and co-benefits for small-scale irrigation and other productive uses of water. Integrated research that involves geospatial analysis and remote sensing can provide the evidence to demonstrate a stronger case to expand RWH globally, and improve their operational, financial and environmental sustainability.

India is staring at water poverty

Climate-change induced deficient rainfall, poor storage of rainwater and water-intensive agriculture are responsible

Photo courtesy: Dhakatimes

According to data released by the India Meteorological Department, the South-West monsoon during June- August 2023 has been below normal in 42 per cent of the districts (see Table). In August, rainfall in the country was 32 per cent below normal and in the southern States it was 62 per cent. In the last 122 years — that is, since 1901 — India received the lowest rainfall in August this year. With only about a month left for the end of the South-West monsoon, the reduced rainfall will not only affect agriculture severely but it could also lead to massive water shortages in different regions of the country. What should be done to prevent water shortage?

Although India has the largest water resources (irrigated area) in the world, water demand has been increasing rapidly due to rapid changes in agriculture and industrial activities in recent times. The net amount of water that can be used in our country in a year is estimated at 1,121 billion cubic meters (bcm). However, the data published by the Ministry of Water Resources shows that the total water demand will be 1,093 bcm in 2025 and 1,447 bcm in 2050. This means that there will be a major water shortage in India within 10 years.

However, this does not mean that there is no water shortage at present. As per the Falkenmark Water Index (which is mostly used for measuring water scarcity throughout the world), wherever the amount of water available per capita is below 1,700 cubic meters in a year, there is water scarcity. Going by this index, almost 76 per cent of people are already living with water scarcity in India.

In Tamil Nadu, which is one of the water-scarce States in terms of per capita availability, water demand was more than its supply even before 1990-91. For example, the total water requirement of Tamil Nadu was 31,458 million cubic meters (mcm) in 2004, but the supply was only 28,643 mcm. This means that Tamil Nadu has been experiencing water shortage for the last 30 years.

Deficit monsoon rainfall alone cannot be the cause of water scarcity. Various estimates show that after 1990-91, the water demand has been continuously increasing due to increased economic activities including the intensification of agriculture. However, no major plans have been made to develop new water sources and strengthen the storage capacity of existing water sources to match the ever-increasing demand for water.

Rivers, small water bodies (tanks and others) and domestic wells met the daily water requirements for many years. Due to poor maintenance of tanks and other small water bodies, water could not be stored adequately even in years of good rainfall. Data show that drought has occurred in India several times due to deficit rainfall. But recently, due to climate changes, rainy days are shrinking.

 

The Intergovernmental Panel on Climate Change (IPCC) has warned in its reports that the climate is changing rapidly which will result in reduced rainfall, both in number of days and quantum. Rainfall deficiency can lead to water scarcity, which will severely affect people’s lives, livestock, wildlife and others. Water scarcity can cause major environmental and economic problems. In the report, ‘Climate Change, Water and Economy’, the World Bank (2016) underlines that countries with water shortages may face a major setback in economic growth by 2050.

The remedies

Central Water Commission data show that the water storage level of 150 major reservoirs as of August 31 was 23 per cent less than last year’s storage level of 146.828 bcm. El Nino, which occurs due to global warming and often changes the rainfall pattern, is becoming the new normal in recent years. There is, therefore, the need to make tough decisions to avoid water scarcity. Everyone forgets the pain caused by water scarcity once the rainy season starts. This kind of mindset needs to change first.

As the total quantum of rainfall and the number of rainy days are shrinking due to climate change, more serious efforts should be made to store rainwater wherever possible. States like Andhra Pradesh, Karnataka, Tamil Nadu and Telangana cannot solve the water scarcity problem without rejuvenating tanks, as all these States have a large number of tanks. The Minor Irrigation Census shows that there are a total of 6.42 lakh tanks, lakes and ponds in India.

However, the Parliamentary Standing Committee on Water Resources has stated in its 16th report on ‘Repair, Renovation and Restoration of Water Bodies’ that most of the small water bodies are encroached upon by government and private bodies. The First Census of Water Bodies published by the Ministry of Water Resources in 2023 has found that 38,486 water bodies have been encroached upon in India. Tough measures are needed to remove the encroachments.

About 85 per cent of the utilisable water is currently used by the agricultural sector. This can be reduced by changing the cropping pattern. Appropriate minimum support policies need to be introduced to reduce the area under water-intensive crops such as paddy, sugarcane and banana. As per the MS Swaminathan committee report on ‘More Crop and Income Per Drop of Water’ (2006), drip and sprinkler irrigation can save around 50 per cent of water in crop cultivation and increase the yield of crops by 40-60 per cent. A total of about 70 million hectares are identified as potential areas for such micro-irrigation method. While making efforts to increase the area under micro-irrigation, farmers should be advised to use such water-saving methods for cultivating water-intensive crops in areas of severe water scarcity.

Water is no longer a public good; it is increasingly becoming an expensive commodity. With the changing pattern of rainfall, severe water shortages are likely to occur frequently in the future. A severe water shortage in 2018 in Cape Town, South Africa, forced the authorities there to ration the supply of water (25 litre/person/day), causing much hardship to the public. This may happen in India, too. Therefore, water should be stored wherever possible during the deficit rainfall period to prevent water poverty in the future.

Country-Abroad .: The world is moving towards severe water scarcity

According to a recent study by the World Resources Institute (WRI), twenty-five countries with a quarter of the world’s population are facing acute water shortages. WRI statistics indicate that these countries routinely use up to 80 percent of their water reserves each year. Demand for water continues to rise with growing population and development around the world, and demand has doubled since 1960. Demand for water has stagnated in developed countries such as Europe and America, but is increasing in Africa. By 2050, worldwide water demand is projected to increase between 20 and 25 percent. The five countries facing the most water scarcity are Bahrain, Cyprus, Kuwait, Lebanon and Oman.

• Twenty-five countries with a quarter of the world’s population are facing acute water scarcity

According to research, globally, nearly four billion people, or half the world’s population, face acute water scarcity at least one month a year. There is no doubt that by 2050 this figure will touch around 60 percent. Such acute water shortages threaten people’s lives, employment, food and energy security. All over the world, the demand for water is increasing faster than the available resources. The increase in water demand is largely the result of rampant population growth, irrigated agriculture, animal husbandry, energy production and industrial development. On the other hand, there is not enough investment in water infrastructure. Lack of efficient water use policies and global warming are having a major impact on the available water supply.

According to the report, countries contributing 31 percent of global GDP, or $70 trillion, will face severe water shortages by 2050. Worryingly, four countries – India, Mexico, Egypt and Turkey – will account for more than half of this GDP in 2050.

Among the 25 countries facing the most water scarcity today are Bahrain, Cyprus, Kuwait, Lebanon, Oman, Qatar, UAE, Saudi Arabia, Israel, Egypt, Libya, Yemen, Botswana, Iran, Jordan, Chile, San Marino, including India. , including Belgium, Greece, Tunisia, Namibia, South Africa, Iraq and Syria. An additional one billion people are likely to live with extreme water stress by 2050. By 2050 the entire population in the Middle-East and North Africa will be living with acute water scarcity. This not only affects people and industries but also poses a major problem for political stability. Take the case of Iran, where poor water management and inefficient use of water for agriculture have worsened the situation to the extent that people took to the streets to protest.

While Africa is the fastest growing economic region in the world today, according to the Global Commission on Adaptation, inefficient water use and poor water management can reduce the region’s GDP by up to 6 percent. India, China and Central Asia could lose 7 to 12 percent of GDP by 2050 due to lack of water management.

As for India, between 2017 and 2021 we lost 8.2 terawatt-hours of energy due to water shortages needed to cool thermal power plants. This electricity could have powered 15 lakh Indian households for five years.

Increasing water scarcity is a threat to the economic development of any country. It also affects food production. Global food security is already under threat. Research shows that 60 percent of the world’s irrigated agriculture is currently struggling with water scarcity, including sugarcane, wheat, rice and corn. By 2050, the world will need 56 percent more food than in 2010 to feed an estimated 10 billion people, which we have to do amid growing water scarcity and climate-driven disasters such as droughts and floods.

Water is essential for agriculture and animal husbandry, generating electricity, maintaining public health, ensuring social security, and mitigating global climate change. Proper water management becomes very important when water scarcity is becoming more and more acute due to factors like rampant population growth, economic development and climate change.

As we discuss the world’s water supply and demand situation, we must also understand that water scarcity does not necessarily lead to a water crisis. Water scarcity can be prevented if some necessary measures are taken in a planned manner. Singapore and Las Vegas have been able to thrive even in the most water-scarce conditions. Local authorities there have implemented good water conservation practices through desalination and other technologies such as wastewater recycling and reuse.

Different methods can be adopted according to the needs of each region. Along with conservation of natural resources, many steps can be taken in agriculture such as efficient use of water through methods like drip irrigation, growing crops using less water, increasing use of solar and wind energy. Apart from the government, industries, society and individuals also need to contribute to this. However, doing all this requires strong political will.

India’s water crisis: The seen and unseen

As many as 256 of 700 districts reported critical or over-exploited groundwater levels as of 2017.

Fetching water in India has been perceived as a woman’s job for centuries, especially in rural areas. As groundwater resources come under increasing pressure due to over-reliance and unsustainable consumption, wells, ponds and tanks dry up. This has escalated the water crisis and placed an even greater burden on accessing water on women.

Several girls are denied education purely because they are entrusted with it.

India constitutes 16 per cent of the world’s population, but the country has only four per cent of the world’s freshwater resources. With the changing weather patterns and recurring droughts, India is water-stressed.

As many as 256 of 700 districts have reported ‘critical’ or ‘over-exploited’ groundwater levels, according to the latest data from the Central Ground Water Board (2017). This means that fetching water in these districts has become harder as the water table has fallen.

A rural woman in Rajasthan walks over 2.5 kilometres to reach a water source, according to a report by the National Commission for Women. This is probably an underestimation, but the bottom line is that our women and girls spend a significant proportion of their time fetching water.

India has been consistently working towards improving access to water. The Jal Jeevan Mission (JJM) guidelines released in 2019 provide provision of tap water connections to households, which holds promise for the women in the country.

If implemented to the last mile, women and girls will not have to go through the arduous job of fetching water. JJM stresses the need to involve women in leading the scheme’s activities, especially at the village level.

Women are required to constitute 50 per cent of the village water and sanitation committees in villages. The ‘Swajal’ programme under JJM comprises a women’s development initiative, designed to upskill them, improve their income-earning capabilities, and connect them to the market with help from support organisations.

However, habitations with less than 25 per cent of its population with access to safe drinking water were granted lower priority in coverage. This indicates that water-stressed regions continue to suffer, and so do women and girls.

Though water, sanitation and hygiene (WASH) policies are gender-sensitive in their design and planning, they fail to measure the gendered impact of the policy. Most evidence available is anecdotal, and there is no quantitative data or monitoring to substantiate how the policy stands to bridge the gender gap.

Policies must employ gender analysis tools to develop a framework for such measurement and integrate it with the management information system or mobile apps to track progress on gendered outcomes. To create an ecosystem for gender transformation, it is crucial for WASH policies to go beyond gender sensitivity and address gender inequality.

Even with all of the challenges, several communities are currently implementing more equitable and inclusive community-led total sanitation (CLTS) and WASH programmes through the Gram Panchayat Water Sanitation Committees, designed to provide adequate, accessible and sustainable solutions for those in need.

Involving women in designing, planning and implementing WASH programmes will socially include them and ensure gender equality, which will help them in decision-making: To deal with school dropouts, and improve literacy and health outcomes.

Our world is packed with knowledge, innovation and capacity, and our journey to achieve goal six of the United Nations-mandated Sustainable Development Goals could just become easier if we remain engaged, influential, and productive to ensure the availability and sustainable management of water and sanitation for all by 2030.

Water crisis in India: Threats and Opportunities for India Inc

India faces daunting water security challenges. The demands of a rapidly industrializing economy and urbanizing society come at a time when the potential for augmenting supply is limited and water issues have increasingly come to the fore. While India hosts approximately 17 percent of the world’s population, it holds only about four percent of its required annual water resources.

India faces daunting water security challenges. The demands of a rapidly industrializing economy and urbanizing society come at a time when the potential for augmenting supply is limited and water issues have increasingly come to the fore. While India hosts approximately 17 percent of the world’s population, it holds only about four percent of its required annual water resources.

In India, more than 600 million people are facing an acute water shortage. About three-quarter households do not have a drinking water facility. Currently, India ranks 120th among 122 countries in the water quality index. By 2030, India’s water demand is expected to be double to that of supply that implies not only water scarcity for numerous people but also a loss of around 6 percent to GDP. This underscores the need for strategic interventions to promote water use efficiency, both at the micro and macro level.

India Inc is an important stakeholder in India’s sustainability story. It also accounts for substantial water use. Various sectors of the industry are competing to use limited water resources that put pressure on the available supply of water and groundwater resources. The UN’s World Water Assessment Program warns of the stark implications, such as lack of freshwater resources on economic prosperity and security.

WATER TREATMENT/OPPORTUNITIES AND REUSE

India Inc has taken cognizance of the magnitude of the water crisis and the role they can play to mitigate it. The corporate should see it as the shared responsibility of companies across sectors to join hands with communities and governments to work on programs for water conservation, recharge and wastewater treatment. On the lines of minimizing the carbon footprint, corporate should also incorporate water management not only as its CSR goals but as a component of its business goals and sustainability plan.

Experts should converge and deliberate on establishing a sustainable water management strategy that will serve as the guideline for the entire industry. They should focus on optimization of water usage for industrial purposes, omitting outdated processes and technology and adoption of suitable recycling practices.

Water forms an intrinsic component of manufacturing cycles of the industry. Corporate has to be mindful of achieving sustainable water consumption while ensuring profitability and fulfilling their business goals.

The role of technology and research and development in encouraging the best water conservation techniques cannot be underestimated. New-age technologies such as smart irrigation systems with ICT and remote sensing are potent tools to encourage water conservation. The onus should be on corporate to foster innovation come up with out of the box solutions as they possess the necessary resources and expertise.

The corporate can also play an instrumental role in devising mass awareness campaigns and information dissemination educating farmers and common populace on the need to use water judiciously.

Equally important is the role of information sharing and collaboration among companies that will encourage the mapping of goals against achieved targets and improvise water management practices. Sharing of technological innovations offer a useful path to greater, mutually beneficial cooperation.

The comprehensive assessment of water requirement and usage by the corporate is essential to facilitate informed policy-making by the government and plugging the loopholes in the policy framework on water.

India Inc must gear to adopt water management on a priority that would enable the entire country to benefit from it through genuine and open collaboration.

Traditional water systems hold the key to India’s water crisis

There is a need to learn from our past, revive traditional water harvesting systems, and enable and empower communities to take back the management of water as a communal resource

Traditional water harvesting system is a diverse range of structures that help harvest rainwater when and where it falls and store it—even replenishing and recharging the groundwater along the way.

The recent pandemic has averted our attention from the alarming water crisis India is facing, however the distressing problem remains. Thanks to short attention spans, many have forgotten that 21 Indian cities ran out of water in 2019, and that unless something radical is done, we will be forced to face a grim reality in the future.

But what if the answer was not ‘something radical’?  What if it was staring us in the face and has been for thousands of years?  What if we have simply ‘forgotten’ the solution?

Water experts across the country have been espousing the benefits of the revival of traditional water harvesting systems—ancient wisdom that saw our ancestors survive many a drought even in the harshest of landscapes.

Indians have had a rich history of managing water. Our forefathers harnessed water that fell during the rainy season and stored it to meet the needs of the community during the dry months. To do this, they used ‘traditional water harvesting systems’—a diverse range of structures that help harvest rainwater when and where it falls, and store it—even replenishing and recharging the groundwater along the way.

Every region in the country has its own unique traditional water harvesting systems depending on the geography and culture of the area. Bamboo pipes and Apatani systems (wet rice cultivation cum fish farming system) are used in the eastern Himalayas while the Gul (traditional irrigation canals) is used in the western HimalayasKund (circular underground well), Khadin (structure designed to harvest surface runoff), Talabs (ponds), Johad (percolation pond), and Baoli (man-made step well) are harnessed in the Thar desert, Rajasthan and in Gujarat; while in Bihar they use ahar-pynes (traditional floodwater harvesting system) – the list goes on.

Back in the day, the belief was that water was a communal resource to be managed by the community for the well-being of all. However, during the colonization, the British replaced this dispersed, decentralized system to manage water, with a centralized one where the Public Works Department took control of the precious resource. As a result, people gave up the responsibility of managing and caring for water, and instead saw it as a resource that was ‘doled out by the powers that be’.

But these incredible structures still exist and many simply lie in disuse, in need of restoration and repair. However, with work, they can be revived to their former glory. Communities dotted across the country are already taking charge of their water future, by reviving these structures, organizing themselves into ‘water management’ groups, and taking responsibility for the water that their lives and livelihoods rely so heavily upon.

Communities in Rabriyawas in Rajasthan, which was once almost uninhabitable due to the lack of water, is today a thriving agricultural hub after the restoration and rejuvenation of ancient nadis (village streams) which have helped sustain life in the desert region for millennia. A village pond or stream is one of the most ancient structures for rainwater harvesting in the state of Rajasthan.

Once the water harvesting structures are operational, there is then a need to promote a more decentralized, integrated approach to managing water—one where grassroots communities act as stewards of their own water and govern it locally, with the active participation of all – women, in particular.

With over 467 ponds rejuvenated in Rajasthan, a variety of Village Development Committees (VDC) are taking care of the operation and maintenance of these water bodies. They monitor water collection and keep a lookout for illegal activities (such as open defecation or flow of sewage water into the catchment areas) at the water bodies. Villages clean the catchment area before monsoon each year so that the ponds are not contaminated. Today, the duration of water availability from each pond can sustain a community for almost an entire year.

But it takes work. People must be mobilized, organized, and empowered with the knowledge that their ancestors once knew how to manage these structures and the water they collect, equitably, to ensure water sustainability for all. This is where there is a role for NGOs and civil society, to enable people to take control back of their water.

Estimates suggest that demand for water will outstrip supply by two by 2030 if we continue with a ‘business-as-usual’ approach. If India is to effectively turn the current water crisis around, there is a need to learn from our past, revive traditional water harvesting systems, and enable and empower communities to take back the management of water as a communal resource. It can be done. It must be done.
