Late 20th century drying and model projections of more arid conditions in the middle to late 21st century have and may further altered the way of life for many in West Africa.  Understanding the processes related to these changes require analysis of regional and global models.  It also requires a better understanding of limited observations for determining emerging trends in West Africa.   Climate variability and change will increase the challenges of decision-makers in West Africa who are addressing issues of urbanization, poverty alleviation, water resources, public health and food security.
