Ethiopia: use of dew water in greenhouses
Roots Up, an Ethiopian social organization that supports small farmers, may have found the solution to combat food shortages in Ethiopia, by creating a greenhouse that turns dew water into a suitable resource for irrigation.
According to a recent study published by the University of Aalto, Finland, Ethiopia does not have a sufficient or safe food supply. The extreme drought of the country is one of the main causes that cause that Ethiopia can not guarantee the feeding of all its population.
This information, originally published on the web portal Ecoinventos, points out that dew water can help farmers grow fresh vegetables, even during times of drought. The greenhouse has a dew collector that helps collect water that would otherwise be lost in the atmosphere. Thus, farmers can produce drinking water for both irrigation and consumption.
According to the information published by the portal specialized in agricultural technology, the greenhouse causes the water to evaporate and rise, when the temperatures of the midday increase. At night, when the collected drops are exposed to cold air, they cool and condense, dropping the water into a storage cistern. This can be repeated each day, allowing the plants to grow, while excess moisture is captured and stored for future use. The collected water can be used both for irrigation and for human consumption.
Comment:
The Institute of Agricultural Research (Inia) is developing a project on the use of covers under plastic for avocados. The investigation began in July of 2016, in the Petorca Valley, Valparaíso Region, an increasingly arid area. The project is financed by the Foundation for Agrarian Innovation (FIA), Exportadora Cabilfrut and the Ministry of Agriculture.
According to Raúl Ferreyra, co-director of the project, this initiative arises from two phenomena that are occurring in the production of avocados. First, there is a need among farmers to find new areas to plant avocados. And secondly, it is a subtropical crop that is being cultivated almost as deciduous, with a winter that does not belong to its place of origin.
It should be noted that there are no other countries that are working under plastic covers. Only South Africa is doing something similar at the research level, but with raschel meshes.
