Watershed Location Map
SEVAI Founder, K.Govindaraju, started his mission with villagers’ interaction in interior villages, Lead a team of gradates and undertook a research study on Rural Cumulative Poverty in 412 villages in Tamilnadu in 1975 and a report was brought out on findings. A monograph had been brought out under the technical support of the Administrative Staff College; Hyderabad for assessing the cumulative poverty hit villages and selected poorest of the poor villages and initiated development intervention based on the study.

The objectives of SEVAI are employment, environment, and enlightenment. The SEVAI believes that the village as a human settlement, a socio-economic entity, with an identity and history of its own, which has grown as a result of interaction with a particular eco system, should not only survive in modern society, but also should grow in strength. ‘Watershed development has been conceived basically as a strategy for protecting the livelihoods of the people inhabiting the fragile ecosystems experiencing soil erosion and moisture stress”. Man and his environment are interdependent.

The changes in the environment directly affect the lives of the people depending on it. A degraded environment means a degraded quality of life of the people. Environmental degradation can be tackled effectively through the holistic development of the watershed. A watershed provides a natural geo- hydrological unit for planning any developmental initiative.

Watershed development and management implies an integration of technologies within the natural boundary of a drainage area for optimum development of land, water and plant resources, to meet the people's basic needs in a sustained manner.
This watershed is an area from which runoff resulting from precipitation flows past a single point into a large stream, river, lake/ pond. Each watershed is an independent hydrological unit. It has become an acceptable unit of planning for optimum use and conservation of soil and water resources.

The concept of integrated watershed development refers to the development and management of the resources in the watershed to achieve higher sustainable production without deterioration in the resource base and any ecological imbalances.
This concept requires the formulation and implementation of a package of programmes with activities for optimum resource use in the watershed without adversely affecting the soil and water base or life supporting system.

The concept assumes more importance in the context of planning for sustained development.
Watershed development aims at preventing watershed degradation resulting from the interaction of physiographic features. It eliminates unscientific land use, inappropriate cropping patterns and soil erosion, thereby improving and sustaining productivity of resources leading to higher income and living standards for the inhabitants in the watershed area.

It therefore involves restoration of the ecosystem, protecting and utilizing the locally available resources within a watershed to achieve sustainable development.

Rainfall failure occurs once every 3 to 5 years and is usually below 50% of the average annual rainfall of the region. During periods of rainfall failure, the groundwater level lowers since fluctuations in the water table levels depend on the rainfall when both surface and groundwater availability becomes critical.

Drought begins to prevail and there is difficult to cope up with the water demand during this period. Similarly, in some locations or areas water shortage is observed just before the rainy season commences. These two situations can be managed if suitable soil and moisture conservation measures are systematically implemented on a small watershed basis. • There are always strong links between soil conservation and water conservation measures. Many actions are directed primarily to one or the other, but most contain an element of both. Reduction of surface runoff can be achieved by constructing suitable structures or by changes in land management.
Further, this reduction of surface runoff will increase infiltration and help in water conservation. Water/soil conservation process.

Watershed is defined as a geohydrological unit draining to a common point by a system of drains. All lands on earth are part of one watershed or other. Watershed is thus the land and water area, which contributes runoff to a common point. Water is essential for all life and is used in many different ways - for food production, drinking and domestic uses. It is also part of the larger ecosystem on which bio diversity depends.

  • Precipitation, converted to soil and groundwater and thus accessible to vegetation and people, is the dominant pre-condition for biomass production and social development in dry lands.

  • The amount of available water is equivalent to the water moving through the landscape. It also fluctuates between the wet and dry periods.

  • Irrigation potential which exists in Tamilnadu is much more than the presently irrigated area for food security.

  • A variety of essential soil moisture and water conservation technologies adopted to reduce the cost of irrigation, extend it throughout and promote sustainable small-scale irrigation on a watershed basis in the PVF supported watersheds will be documented.

  • Watershed technologies are essential especially in drought-prone areas. Even though drought is a purely natural calamity caused by the failure of (monsoon) rain, it can be minimized by careful planning and operation.

  • During good rainy years, excess rainwater should be stored in the soil and also underground using suitable soil moisture conservation measures and water harvesting structures on a watershed basis. This stored water can subsequently be used for irrigation.

  • The word watershed refers to a “contiguous area draining into a single water body or a water course” or “it is a topographical area having a common drainage”. This means that the rainwater falling on an area coming within a ridgeline can be harvested and will flow out of this area thorough single point. The term watershed development encompasses additional dimensions like equity, sustainability, gender and peoples participation. It has become a trusted tool for the overall development of the village and people living within a watershed area.
    Objectives of watershed management implemented in SEVAI in
    Dasilnaickanoor/Thottiyapatty/Kakayampatty cluster.
    The different objectives of watershed management programmes achieved are:

    1.To control damaging runoff and degradation and thereby conservation of soil and water.

    2.To manage and utilize the runoff water for useful purpose.

    3.To protect, conserve and improve the land of watershed for more efficient and sustained production.

    4.To protect and enhance the water resource originating in the watershed.

    5.To check soil erosion and to reduce the effect of sediment yield on the watershed.

    6.To rehabilitate the deteriorating lands.

    7.To moderate the floods peaks at down stream areas.

    8.To increase infiltration of rainwater.

    9.To improve and increase the production of timbers, fodder and wild life resource.

    10.To enhance the ground water recharge, wherever applicable

    Actualize the vast untapped growth potential of Indian agriculture

  • Strengthened rural infrastructure to support faster agricultural development

  • Promoted value addition, accelerate the growth of agro enterprises among self help groups

  • Created employment in rural areas

  • Secured a fair standard of living for all agriculturalists and SHGs

  • Discouraged migration to urban areas and face the challenges arising out of economic liberalization and globalisation.

  • Resource mobilisation for sustainablity such as soil, farm equipment, loans and packages of practice of different crops.

  • Improvement of the Quality soil is one of the most important farming inputs.

  • High yields and good produce can be achieved only when the right type of soil is used for a certain crop.

  • Agriculturalists / individual entrepreneurs -setting up of small dairy farms for milk production.

  • Popularization of new technologies/tools/techniques for commercialization/ adoption.

  • Introduction of new concepts to improve farming systems.

  • Upgradation of skills by exchange of technical know-how.

  • Development of agriculture and allied sectors by better farming practices and cropping patterns, judicious use of water by introducing drip irrigation system, yield enhancement etc. as a result the village where nearly three- fourth population was below poverty line, has become self sufficient and is surplus in food grains, today.

  • Development of managerial skills and capability among people with low level of education, exposure and training.

  • Enough scope for women for self development.

  • An appreciable change in the attitude of the people with high degree of moral standards and ethics.

  • Over all improvement in the quality of life of the people, and conservation and use of the natural resources in a very sustainable manner.
