Agronomists anticipate that climate change will generally have an adverse effect on agricultural productivity, particularly in tropical countries and in some temperate countries where the growing season is in the hottest part of the year. This adverse effect will potentially increase malnutrition through multiple channels. First, for the poor subsistence farmer, and productivity losses directly reduces household food consumption. Second, global productivity reduction leads to higher prices, making even poor urban consumers less food secure.
CSA endeavors to enhance agricultural productivity under climate change while at the same time reducing greenhouse gas emissions per unit of production. CSA endeavors to create win-win scenarios by not asking farmers to reduce emissions unless the strategy also results in higher productivity or more profitable farming. (Individual farmers, apart from government policy, do not have any direct incentive to reduce their own missions, since they bear the cost of their own mitigation efforts without being able to capture the benefits from the mitigation. Apart from international incentives, the same is true for including mitigation activities in any national plan.)
