However, information on the extent of the problem, its future projections, and the contribution of fanners to water challenges likely vary significantly from India to China and the United States. Large companies operating in the United States may also be more proactive than in the two other countries due to their capacity to provide flexible responses. Just like companies harvesting lettuce in California are able to change location three times a year to respond to climatic conditions, they may also be able to adapt to changing water supply and climatic conditions. In particular, governments should address exogenous risks by increasing the probability of response by farmers (0). This can be done, for instance, by providing more and better information on the cost of inaction and supporting effective response, but it may also involve regulatory instruments that will ensure that fanners take actions.
