Info

Although the irrigated land surface constitutes only 13% of regional arable land area, this activity generates 40% of the regional agrarian income (JCCM, 2000). This elucidates the role of irrigation as a catalyst to development, and provides an idea of the limited economic profit value of rainfed in the zone. It should not be forgotten that the average precipitation in agricultural areas of CLM is around 500 mm/year, while the reference values of evapotranspiration surpass 1,100 mm, characterizing the agricultural area as semi-arid (Fig. 11).
