"The implications of irrigation as a planned adaptation measure on an economy wide context"
by Parrado, Ramiro and Anna Dellarole

Agricultural activities depend on specific climate conditions such as temperature, CO2 concentration, precipitation, water availability, as well as frequency and intensity of extreme weather events. It is thus expected that they will be particularly sensitive to future climate change leading to changes in agricultural productivity, level and regional distribution of food production. Therefore, there is a need to implement specific adaptation measures to cope with the negative effects of climate change. In this context, irrigation activities could play a key role, especially in developing countries. However, given that irrigation activities require specific resources, it is also necessary to include several economic aspects in the analysis. Among these aspects it is important to consider irrigation costs and the interaction of irrigation activities with the rest of the economy. Also important are the repercussions in domestic and international markets following expected productivity shocks, as well as the mitigation of impacts which could be provided by adaptation measures. These elements offer the basis to pose the following research question: Which are the economic implications of irrigation as a measure of planned adaptation for the agricultural sector, considering indirect economy wide effects as well as international trade?
To address this question we use a multi-country and multi-sector recursive dynamic Computable General Equilibrium (CGE) model which takes into account international trade flows. In addition, we extend it with specific features to include irrigation as a planned adaptation measure. This comprises enhancing the model, and its database with information on rainfed, irrigated land, and irrigation services. These modifications allow us not only to assess impacts of climate change with an improved model, but also assess the contribution of irrigation as a specific adaptation action.
