Water use in agriculture plays a critical role in any discussion of
water and food security, since farming activities account for around 70%
of water used in the world today. Inefficient agriculture contributes to
a great pollution of surface water and also to groundwater depletion
with its associated consequences. Also excessive use of nutrients and
pesticides are key sources of water pollution in many regions. On the
one hand, sustainable management of water in agriculture is critical not
only to increase agricultural production, but also to support continued
economic growth in other sectors. On the other hand, agriculture faces
increasing water challenges, ranging from climate change, increasing
water competition from other sectors, and gradual water quality
deteriorations. The objective of this book is to serve as a forum to
discuss advance solutions to improve the management of agricultural
water risks in developing countries.
