Methodologies and Tools to Evaluate Climate Change Impacts and Adaptation
Compendium on methods and tools to evaluate impacts of, vulnerability and adaptation to climate change. Final draft
4 Sector-Specific Tools
4.1 Agriculture
The agricultural sector tools described in this compendium, listed in Table 4.1, range from sector-wide economic analyses to farm-level crop models. The crop process models address the impact of various management and climate change scenarios on single crops (e.g., WOFOST, ICASA, ALFALFA, ORYZA), multiple crops (e.g., APSIM), and entire ecosystems (e.g., CENTURY). Other tools can be used to examine particular ecological factors or processes (e.g., ACRU) or support bigger picture strategic adaptation decisions (e.g., MAACV, RRI). The economic models (e.g., Ricardian analysis and input-output accounting) assist the user in evaluating the economic impacts of changing land values, supply and demand, and commodity production resulting from climate change. There are substantially more agricultural sector tools than there are tools in other sectors. This is because many agricultural models are crop specific or are applicable only to particular regions, whereas models in other sectors tend to be more generally applicable.
