Description

Rainwater Harvesting & Groundwater Recharge in Barmer, Rajasthan Barmer is the second largest district in the western of Rajasthan forming the Thar Desert. The variation in temperature in various seasons is quite high. Barmer falls under arid western agro-climatic zone with summer temperature ranging from 46 °C to 51 °C and winter temperature dropping to 0 °C. In past decade, every third year in Barmer was declared as a drought year. The livelihood of Barmer inhabitants is primarily based on rain-fed agriculture and dryland farming followed by livestock rearing. Dryland farming in the region is characterised by climatic risk, low cropping intensity and diversification in crop selection. To ensure sustainable livelihoods, livestock rearing is used as a supplement. The average rainfall in the district is 277 mm per year distributed over 10-15 days. TechnoServe is a non-profit economic development organization founded in 1968, that develops business solutions to poverty by linking people to information, capital and markets. In India they are operational in for seven years, with on-field footprint across Rajasthan, Maharashtra, Bihar, Uttar Pradesh, and the North-Eastern states. The agency helps bring proven expertise in agricultural value chain interventions including large scale farmer training programs, extensive capacity-building programs for farmer producer organizations and companies across India. TechnoServe and Cairn India are partnering to promote social and economic development in Barmer, Rajasthan under the Barmer Unnati project. In addition to capacitating rural entrepreneurs, skills and human resources, improving agricultural yields and incomes. TechnoServe is also improving management of natural resources like Soil & Water through construction and renovation of individual and community level structures. The project identified construction of Khains and run-off harvesting structures as most relevant interventions towards prevention of water run-off and soil erosion, harvesting rainwater in agricultural field for crop production and groundwater recharge in arid regions of Barmer. With the financial support from CAIRN CSR, TechnoServe constructed 157 small rainwater harvesting structures known as Khadin structures in the farmer’s field during 2014 and 2015 in Barmer & Baitu Block. In addition to this, 2 community Khadin structures and 2 Nadi (village water ponds) structures are renovated at group and community level to harvest the rainwater which contribute towards water security as well as recharging the ground water in Barmer region. During Kharif 2015, it is estimated that about 20,47,000 cum Rain water is being harvested in such structures, which are allowed to percolate into the soil profile and hence contributed towards ground water recharge.

Objective

1. Construction of Small Water Harvesting Structures (Khadins) A Khadin is an ingenious rainwater harvesting structure, designed to harvest surface runoff water for agriculture and ground water recharge. It is an earthen embankment built across the general slope which conserves the maximum possible rainwater runoff within the agricultural field. The Khadin system is based on the principle of harvesting rainwater on farmland and subsequent use of this water-saturated land for crop production. The above photographs shows the amount of Rainwater harvested in a single rain during June- July,2015. During the year 2014 and 2015, the project took an initiatives to construct such structures and able to complete 157 structures in Barmer & Baitu block in rainfed regions. It is estimated that about 9,42,000 cum of rain water is harvested in situ and contributed towards ground water recharge and enhance the soil moisture regime for kharif crop production. Enhance the Production & Productivity Khadin can make arid wasteland productive and enhance the production and productivity of the land. Depending upon the amount of rainfall and consequent runoff received during the monsoon, one or two crops are grown. There is 2-3 fold increase in agriculture production, in comparison with non-Khadin conditions. This system assures the farmers of at least one crop even in very dry times. During 2015 kharif, even in the irregular rainfall in Barmer, the farmers with Khadin were able to grow good crops in Khadin structure, while others farmers without Khadins failed. 2. Renovation of Nadi Structure Nadi, a traditional Water Harvesting Structure in the Western Rajasthan is excavated or embanked for harvesting meager precipitation, to mitigate the scarcity of drinking water in the lean period i.e. early summer & during summer. Rain water collected in the Naadi from the runoff are made available for periods starting four months to a year after rain, depending on the catchment characteristics, the amount of rainfall received and its intensity. This is an ancient practice and the Nadis are the most important water sources of the region used for drinking purposes by human beings as well as livestock. But in due course of time, these Nadis are silted and hence the water storage capacity is reduced to a large extend. Hence, these Nadis are dried up during summer. Again due to lack of proper management practice, lack of maintenance, the community suffered a lot to get the water for drinking. With due request from the community and Panchayats, the project taken up the renovation work of such two Nadis with active participation and contribution from community. The process adopted in developing a Nadi is in partnership with Community. After obtaining the No Objection Certificate from the Panchayat, the renovation work initiated with active participation, supervision and contribution with active community participation. During the year 2015, two such structures are renovated and completed before the rain during June, 2015 and allowed the rainwater entry and harvested in the structure. During July,2015, it is estimated that 1,90,000 cum of water is stored in the two Nadi structures over a storage area of 5 hectares and also contributing towards ground water recharge. 3. Construction of Community Khadin Structures Community Khadin structures are similar Rainwater Harvesting Structures with respect to the large catchment area (more than 100 hectares) in a larger area of storage. This is primarily a runoff harvesting structure, designed to harvest surface runoff water for agriculture and ground water recharge. It is an earthen embankment built across the general slope which conserves the maximum possible rainwater runoff within the agricultural field. The Khadin system is based on the principle of harvesting rainwater on farmland and subsequent use of this water-saturated land for crop production. Two large community Khadin structures for two group of farmers (74 Farmers) are constructed in the Bhadkha Gram Panchayat of Barmer Block. With active participation of the farmers, the structures are completed during June,2015 and are ready before rain for harvesting and storing of water during rainy season. Please find some of the photographs showing the amount of water stored during rain which contributed towards ground water recharge.
