Climate change is likely to influence agriculture and water sectors and eventually food security and livelihoods of a large section of the rural population in developing countries. Extreme weather events such as droughts, floods, heat waves and changes in the monsoon rains are already affecting agricultural production in India and farmers are struggling to adapt and sustain their livelihoods due to these changes. The ClimaRice project is testing and validating selected technologies on farmer's fields in India, in close co-operation with farmers and local agencies. The project follows a multidisciplinary approach, integrating natural and social sciences and bringing science closer to policy makers to enable them to frame suitable policies to adapt to climate change and extreme weather events.

Goal and objectives

The main emphasis of the ClimaRice project is to develop local ownership through active participation of stakeholders in the design, implementation, and management of adaptation strategies to ensure the sustainability of rice production.

The overall project goal is to:

Reduce uncertainties in future monsoon projections, demonstrate the applicability of selected adaptation techniques and enhance stakeholder adaptive capacity to climate change on rice production and irrigation water management practices through field demonstration, institutional and capacity strengthening.

Main objectives:

  • To reduce uncertainties in climate models' projections, and demonstrate the applicability of selected adaptation measures
  • To standardize and mainstream climate change adaptation measures/ technologies / practises, and activities developed in the ongoing project into the regional adaption programs
  • To standardize methodologies that could be up scaled to other areas impacted by climate change.
  • To actively encourage stakeholder participation and build stakeholder capacity including those of farmers, agricultural and water managers to climate change adaptation and increase their awareness on the uncertainties involved and on the difference between natural climate variability and climate change

Study Areas

ClimaRice consists of two study areas located in the Cauvery River Basin, Tamil Nadu, and Krishna River Basin, Andhra Pradesh, in India.


Study area, Tamil Nadu 
The study area is located in the lower part of the Cauvery river basin, Tamil Nadu, India. The region experiences rainfall during both the summer southwest (June through September) and early winter northeast monsoons (October through December), with the peak rainfall during the north-east monsoon season.
Study area, Andhra Pradesh

The study area is located in the lower part of the Krishna river basin, Andhra Pradesh, India. It is the fourth largest river basin in India in terms of annual discharge and the fifth largest in terms of surface area. It broadly covers the states of Karnataka, Andhra Pradesh and Maharashtra.

Publications in the project

To document


ClimaRice II has explored the potential for climate adaptation and mitigation through online dissemination of pest risk forecasts to rice farmers. Weather-driven mathematical models incorporating scientific insights on the biological responses of plant pests to climate can be linked to automatic weather station networks to provide pest risk forecasting / forewarning / early warning to rice farmers


Gender analysis is an important component of the Climarice project in order to better understand the ways in which women and men are differently affected by climate change and how they are adapting. During the current year, a preliminary analysis has been carried out on gender issues. This will be followed by a detailed study in 2011 in selected areas in Andhra Pradesh and Tamil Nadu. The expected outputs will provide more detailed analysis on gender differences and a better understanding of men and women’s vulnerabilities to climate change and clarify the special needs of men and women to adapt. The overall goal is to contribute towards developing appropriate strategies and policy to address gender issues in climate change.
