In this dissertation I evaluate the potential effects of climate change on agriculture by deploying state-of-the-art econometric techniques to the contexts of Mexico and California. In the first chapter, I investigate the effects of climate change on Maize productivity in Mexico using a panel approach. Maize is Mexico's most important crop and any effects that climate change may have on its productivity might also have food security implications for the country and for rural families that rely on Maize mainly as a source of food rather than as a source of income. The findings of chapter one confirm the sensitivity of rainfed Maize to climate change and highlight the role that irrigation could play as an adaptive measure. In the second chapter, I deploy a version of the Ricardian (or cross-sectional) approach that relies on a shadow measure of land productivity rather than on market land values. Markets in developing economies are often non-competitive or incomplete and in such settings the welfare implications of climate change derived using market land values could be misleading. A shadow value of land reflects more properly the market setting in which farmers take decisions. This novel version of the Ricardian approach is applied to the Mexican context and the findings indicate that market land values underestimate the negative effects of climate change on agricultural productivity . Finally, chapter 3 evaluates how access to a relatively new form of water storage, groundwater banking, has shaped the long-term investment decisions of farmers in California's Kern County. The empirical strategy of this chapter relies on a long-difference approach applied to panel data of individual cropping decisions. Results indicate that access to groundwater banking has decreased the risk associated to water curtailments in dry years and incentivized a switch from annual to perennial crops. As climate change modifies hydrologic flows in California, storing water as groundwater will likely be an important tool to managing drought risks.
