Venezuela is a very diverse country, with a high topographic and climatic changeability that allows the formation of diverse ecosystems. Due to its tropical location, the altitude changes promote drastic changes in the structure and function of the vegetation.


Desertification status

Venezuela is covered by a significant surface of dry arid, semiarid and sub-humid grounds, covering approximately 45% of the territory, which are highly susceptible to the desertification process. According to the Ministry of the Environment, 43% of the territory is been threatened at the moment. The most affected areas include the states: Falcon, Lara, Zulia and Sucre. In Falcon more than 70% of the surface is severely affected. The main causes of the desertification are the intensive deforestation for the establishment of monocultures and cattle, over grazing, the illegal wood extraction for construction and the wrong town planning. The desertification processes have turned out to be accelerated by the climate changes; the maximum temperatures have exceeded 45°C and, consequently, the evapo-transpiration has increased severely; especially in the soils deprived of vegetation there have been registered temperatures of 60°C. Also, an intrusion of saline waters has been observed in the aquifers of the north-coastal areas, determining the loss of arable soils due to salinization.

Water management strategies

In the analysis it was stated that one of the best practices for the tropical arid areas is the diversification of the production systems, which allow the producer to obtain diverse products in a smaller space and which use the native vegetation as a source of food for the goat cattle. The combination of native leguminous trees with Aloe Vera and with cocuy (Agave cocui) are high priced on the market, do not need irrigation for being succulent and grow very well with organic fertilization. The producer can commercialize multiple products.

 

As for the water management, during the analysis the team realized about the big water shortcomings for the agriculture in the arid zones. The proposed management, which could be more successful, is the organization of a water source to be distributed equitably between the settlers of the enclosure. Another interesting practice is the "Torobas", which are barriers that are constructed by wood and earth in order to retain the moisture.
