After 1994, new droughts and heat waves 'increased the lack of water because agriculture needs more and more water. Nonetheless this cultural method is compacting soil by the reduction of organtc matter and by !he heavy falls of rain No solution has been found yet, they have to find new resources of water or change agricultural irrigation methods 1o save water and build up a sustain.able development for this semiarid area. |
