In this episode you will learn how temperature and precipitation changes will impact agriculture and food production in the developing world and how these impacts vary per region and how they differ under different levels of warming (4 C warming vs. 2 degree warming). For instance, temperature and precipitation changes will result in lower crop yields at lower latitudes and drought-affected areas worldwide may triple by the end of the century. In addition you will learn how the impacts of climate change on agriculture depend on three interrelated factors: temperature-induced effects, precipitation-induced effect, and the CO2 fertilization effect. Further stress is put on agricultural needs as the world’s population is expected to reach about 9 billion by 2050 and the demand for food is expected to grow by 70-100%, according to some studies.
