Abstract

Over 60% of agriculture in India is rainfed; this provides employment opportunities to a large percentage of the population while also contributing substantially to the country's GDP. In recent years rainfed agriculture is becoming unviable because of unpredictable rainfall. As a temporary solution, farmers engaged in agriculture, overcame this shortcoming by using groundwater through tube wells. The policy governing groundwater use in the country is ambiguous to say the least and its implementation is arbitrary. Therefore, groundwater use in many parts of the country has increased exponentially and have led to several adverse effects. The impacts are particularly dire on the poor. Proposed innovations in the efficient use of groundwater to supplement rainfed agriculture are limited to small geographical areas. Experiences of using the System Dynamic (SD) methods in different parts of the world and adopting technology to promote sustainable use of groundwater are well documented. Participatory GIS experiences in order to achieve equity and increase community participation have led to positive impacts for the poor. This paper reviews recent publications in 5 areas connected to rainfed agriculture: rainfed agriculture, climate change, groundwater, system dynamics(SD) and participatory GIS. While focusing on issues of rainfed agriculture and its protection in the Indian context It particularly emphasises the integration of technology and participatory methods in agriculture and groundwater-related issues. The paper concludes with recommendations for scaling up the innovation of integrating socio-technological aspects such as system dynamics and participatory GIS.

An Exploratory Research to Maximize Irrigation Potential for Rainfed Crops through Participatory GIS Mapping, Design and Layout of Pipeline Network for Collectivising and Sharing of Tubewells

Over 60% of agriculture in India is rainfed; this provides employment opportunities to a large percentage of the population while also contributing substantially to the country's GDP. In recent years rainfed agriculture is becoming unviable because of unpredictable rainfall. As a temporary solution, farmers engaged in agriculture, overcame this shortcoming by using groundwater through tube wells. The policy governing groundwater use in the country is ambiguous to say the least and its implementation is arbitrary. Therefore, groundwater use in many parts of the country has increased exponentially and have led to several adverse effects. The impacts are particularly dire on the poor.

Participatory GIS experiences in order to achieve equity and increase community participation have led to positive impacts for the poor.
