- Resumen es exacto "Throughout history, water and agriculture have been closely linked. Most of the world's food arise from rainfed agriculture, which depends on soil moisture almost exclusively due to precipitation. In the coming decades, agricultural production will take place in the context of a changing climate, awaiting major changes in the frequency and severity of floods and droughts. Rainfed agriculture will continue to be particularly vulnerable to excesses and deficits in rainfall. This makes it essential to develop sound strategies to limit environmental and economic losses associated with extreme events and regional climate changes. Understanding the links between agroecosystems, water, and food production is important to think about productive strategies by agricultural producers in current and future conditions. For this, it is necessary to continue deepening the knowledge on the functioning of agroecosystems and their interrelation with the availability of water. Producing information relevant to producers decision-making requires a comprehensive and inclusive understanding, not only of the physical and biological links between crops and water, but also of the economic and social contexts in which they take decisions. This thesis aims to advance in the characterization of the links between hydrology, climate, land use, and agronomic decision-making in a sub-basin of the South Salado River in the Pampas plain, one of the main cereal and oilseed productive regions of the world, using numerical modeling as the main tool for analysis."
