After five years of studies, Cuba presented two work tools for adaptation to climate change in the agricultural sector, as part of a project focused on food sustainability, sponsored by UNDP. The Basal project, food bases for local food sustainability, led by the Cuban Environment Agency showed the preliminary results of a model that allows water management taking into account climatic scenarios and agricultural variables. The WEAP (Water evaluation and planning), as it is called one of these tools, also favors the evaluation of the impacts of the different climatic scenarios in the agricultural sector. This model was applied in the locality Los Palacios, of the western province of Pinar del Rio, where there are three superficial hydrographic basins and of great significance in the production of rice. It allows, according to its developers of the Institute of Tropical Geography, to estimate the water demand of the users of the area by type of crop and delivered supply. It also allows, explained the authors, project the possible rules of operation of reservoirs, to anticipate situations of water stress and decide more precisely the beginning of planting any crop waiting for favorable situations. Another of the tools, Bioma (Biophysical models applications), by its acronym in English, allows to evaluate the future behavior of agricultural yields in different regions and diverse climatic scenarios. It is, the authors of the Cuban Institute of Meteorology, stress the duration of different crops, agricultural management in terms of optimal dates and water management among others. Considered a project of great significance for the socioeconomic and environmental development of the island by supporting the tasks of adaptation to climate change in the Greater Antillean Islands, Basal is implemented by the UNDP with the participation of the European Union's Research Research Center.
