The publication of the Stern Review on the Economics of Climate Change and the Fourth Assessment Report by the Intergovernmental Panel on Climate Change in 2007 have pushed the scientific and public debate on climate change a decisive step forward. It is now beyond doubt that anthropogenic greenhouse gas emissions are the main cause of the recently observed climate change. The agricultural sector is directly affected by changes in temperature, precipitation, and carbon dioxide concentrations in the atmosphere. If global temperature increases beyond 2°C world food security could be threatened, given a continuous increase in world population to unprecedented levels above 9 billion this century.
This article covers issues related to both crops and climatic conditions. Climate stress on crops and solutions to counteract these stresses are discussed. Some of the solutions reported are the development of drought and temperature resistant species, crossing food crops with their wild relatives and other genetic engineering solutions. Seed banks and their maintenance are also discussed. The development of energy crops is a strategy to produce alternating energy without impacting food security and impact on the environment and is a possibility. the need for research on crop improvement is presented as are some examples of studies made.
