In the old cultivated land of the Sierra and Selva region, this natural vegetation is only present in relics far away from the roads. There it has been replaced by deforested cultural landscape areas and hillside terraces with occasional uniform eucalyptus plantings. The vegetation, especially in the lowlands, undergoes drastic changes every few years during the rainy season. They are caused by unusually heavy rainfall as a result of the El Niño. During such years, the otherwise parched Costa region is briefly covered by a carpet of green vegetation.
IRRIGATED AGRICULTURE TODAY
The irrigation industry in the region faced two challenges:
1. to increase the water supply overall in order to be able to expand the irrigation areas, and
2. to adjust its natural fluctuations in the course of the year to the water requirements for cultivation.
These tasks were solved as part of a development aid project through transfers from the Montana / Selva and through storage structures for water regulation (Tinajones reservoir).
In addition to the water management issues, a number of other aspects had to be taken into account when expanding the irrigation system. Since drainage in irrigation systems was often not given enough attention in the past, the high evaporation resulted in soil salinization, which led to considerable reductions in yield. That is why the expansion of irrigation and drainage on an equal footing is of great importance at the present time.
