In this week in which the United Nations (UN), celebrates the World Water Day, we remind you that the access to water and sanitation have been internationally recognized as a human right.
In Arid Brazilian, one of the most populous arid areas in the world, about of 26 millions of people, of which 10 millions live in rural areas, coexist with the Shortage of this liquid so precious. In addition to the hot and dry climate, the low availability of water in this region is related to several factors: unpredictability of rains; little depth of soils; high temperatures and high evaporation rates.
With the aim of fostering the development of Sustainable in the Northeast, Adel understands that it is possible to balance the social development, economic and environmental sustainability. This means that strategies need to promote coexistence with the semi-arid, not just in the fight against drought. To do this, investments in traditional knowledge combined with modern technical-scientific knowledge are needed, to ensure greater scalability and replicability to these strategies.
The use of socio-environmental technologies low-cost, low-cost, family farming it is strategic for living with the semi-arid and to cause changes in the scenario of water scarcity for human consumption and food production. The social technologies of water safety implemented by Adel through its programs and projects are alternatives that help transform the reality of the semi-arid in relation to access to water, contributing to improving the quality of life of families.
Among the technologies worked, we highlight the construction of Tanks "telhadão" for the storage of rainwater, drilling of deep wells, recovery of artesian wells, desalination of wells through photovoltaic solar energy e Workshops with families about sustainable production and water management and use, developed in three states in the Northeast: Ceará, Rio Grande do Norte and Pernambuco.
Second Wagner Gomes, Director of business at Adel, initiatives focused on water security, seek to develop with families and community leaders a self-management of the waters. "Through courses and workshops in operation and management of social and environmental technologies for access to water for human consumption and food production we have contributed to advance in these models. But, it is necessary that the management of rural water supply services be institutionalized and regulated in the country", highlights.
Water Security Social Technologies implemented in the Semi-arid Northeast
The impact of social technologies of access to water on the lives of rural communities is immense. Their implementation provides not only access to drinking water for human consumption, but it also boosts the food and nutrition security of families. Throughout its trajectory, Adel have implemented together with the families of the Semi-arid Nordestino, appropriate technologies to overcome local difficulties in accessing water resources in order to build a coexistence with the semi-arid increasingly sustainable and effective.
We list below some of the technologies implemented:
Roofing Cistern – The tanker "telhadão" is a technology of capturing rainwater through a roof of 100 m ², in the form of shed. The roof captures rainwater and by a system of gutters and pipes leads her to a cistern with a capacity of 52,000 litres of water. The area covered has many utilities. Farmers(the) use to store food in the form of hay or silage, keep the tools, creation of small animals, among other uses.
Deep Well – The deep well is an opening made in the soil for the purpose of capturing groundwater. Well drilling sites are defined from a geophysical prospecting study that identifies the areas with the highest water potential. To start activities, Adel permits all wells with the agencies responsible for. In addition to seeking environmental authorization, which is essential for access to water resources to occur in a sustainable way. After drilling the deep wells, the next step is the implementation of water supply systems to ensure access to water resources for human consumption, food production and social and productive inclusion.
Artesian Well – An artesian well is a tubular well made in the soil for water extraction purposes, in which comes out of it gushing naturally, so why, it's also called a well gushing. The most frequent causes for the recovery of artesian wells are the lack of cleaning and periodic maintenance, well coating column break, change in constructive characteristics, prolonged operation on an inadequate regime, exhaust of the underground reserve and fall or imprisonment of objects. This action meets the longings of the residents of these localities, benefiting directly from families who need the artesian well daily.
Solar Desalination – Solar desalinator is a social technology that has provided numerous socioeconomic and environmental benefits, which enables water security through the supply of drinking water, promotes social transformation in the face of the management of local water resources and uses solar energy. The water that comes out of many wells in the interior of the Northeast has enough salts, making water bad for human consumption. The way out is to use a desalinator, the equipment removes excess salts from the water through a physical-chemical process, making it sweet and fit for consumption. Each farmer is entitled to a certain amount of litres per day. So residents who once depended on other water sources, now have access to drinking water near home.
