ABSTRACT
This chapter provides a better understanding of climate change and its impacts on rice yields in Southeast Asia, which can lead to the enhancement of food security by developing efficacious adaptation measures to climate change in the region. As crop production is heavily reliant on hydroclimatic variables, it is widely recognized that climate change presents a significant risk to agriculture globally. Climate change has been and will continue to be a critical factor affecting rice productivity on the Indochinese peninsula, with adverse impacts already increasing, necessitating urgent action. Global Climate Models reveal large-scale patterns of change, and outputs are relatively coarse, at approximately 150–300 km by 150–300 km. Global climate simulations indicate large-scale patterns of change associated with natural and anthropogenic climate forcing. The scope of the system analysis determines the spatial scales of crop models. Various crop models have been widely used to assess the impacts of climate change on crop yields.
