Addressing the complexities in the relation between water and food production: avoiding too simplistic views, and future prospects
Fereres Castiel, Elías
Trabajo presentado en la Final EURO-AGRIWAT Conference (Water Footprint of agricultural products: progress, challenges and solutions), celebrado en Wageningen del 7 al 9 de marzo de 2016.
Crops consume large amounts of water as determ
ined largely by the en
vironments in which
they are grown. The introduction
of the water footprint concept should have conveyed this
reality to the general public; nevertheless, urba
nites are often surprised by the magnitude of
crop consumptive use, as exemplified by the barrage of media articles criticizing the
excessive consumption of almonds in the rece
nt California drought. Pressures from other
sectors of society and water scarcity due to periodic droughts will force farmers to optimize
the use of water in crop production.
All optimization approaches must be based on
knowledge on the yield response to water
and, in turn, on the physiological and agro
nomic factors determining such response. The
ultimate goal is to be able to accurately
assess the economic returns of using different
amounts of irrigation water and to evaluate th
e risks/rewards of seekin
g/acquiring additional
supplies in the event of a drought. The presentation will review the state of the art in
predicting crop yield response to water using empirical and mechanistic approaches, and will
analyze the role of key physiological and agronomic processes in improving the efficiency of
water use in crop prod
uction in the future.
