Evaluating the effects of climate change on crop yields and farming methods worldwide

Climate change may have a substantial impact on agricultural productivity around the world, yet the effects of climate change are conditionally heterogeneous. The impact that climate change will have on crop yields is a major source of concern. Natural resources and the distribution of calories consumed are key factors in food security. All three will be less distributed as a result of climate change. The strategy will be to solely consider total natural resources, which could be a decent estimate of regional food security. On the other hand, a worldwide analysis of food security is inappropriate. Two billion people would still lack access to adequate calories in calorie-neutral food systems, and rising temperatures will drive up the cost of food in comparison to other products. The impact of climate change on food production systems is another major source of concern.
