For many years, scientists have been predicting the impact of climate change. In Latin America and the Caribbean, predictions range from water shortages to an increase in the frequency of extreme weather events. The effects of climate change could significantly reduce the ability of ecosystems to operate properly, threatening development projects throughout the region.A report from
the Working Group on Climate Change and Development in the UK describes the
effects of climate change and environmental degradation in Latin
America and the Caribbean.

This conference paper explores food market vulnerability and security as related to rainfall shocks across Sub-Saharan Africa by applying econometric methods across a wide range of developed and developing countries. The paper is focused on methods of improving access to affordable food supplies for developing countries during times of dire need.

MarkSimGCM is a stochastic weather generating tool, which uses the well-known MarkSim application, a tool that generates simulated daily weather data specifically designed for use in the tropics, including rainfall, maximum and minimum temperatures and solar radiation. It provides files of daily weather data that are completely compatible with the DSSAT (Decision Support System for Agrotechnology Transfer) crop modeling system
