Climate change, food security, and future scenarios for potato production in India to 2030

摘要

Much of the literature on future food supply in Asia focuses almost exclusively on the cereal crops overlooking the growing importance of other food commodities and their potential to help sustain Asian food systems and food security in the decades ahead. This study utilizes a multi-period, agricultural partial equilibrium economic model, linked with a set of crop, climate and water models to estimate potato supply in India for the period 2010 to 2030 according to three scenarios: high, moderate, and slow growth. According to the high growth scenario, potato supply could increase over 37 million metric tonnes while the more pessimistic scenario estimates increases in production of nearly 24 million metric tonnes. The findings point to opportunities for agribusiness initiatives in input markets and technical services for potato cultivation. They also call attention to the benefits to be derived from policy initiatives in support of future activities on and off the farm intended to optimize the potato sector's contribution to food production, income, employment, and food security in India in the years ahead.
