“…Rain-dependent environments occupy the largest area. The capture and management of rainwater have been a popular technique developed by different peoples in different parts of the world, and there are thousands of people, especially in arid and semiarid regions [70]. The population throughout the history of coexistence with drought was developing different strategies to deal with human, animal, and primary food, fiber, and energy production [71].…”

Anthropogenic activities have altered the atmospheric composition since the industrial era, especially with the increasing greenhouse gas emission due to fossil fuel combustion, cement production, and land-use change. The Brazilian semiarid, covering approximately 969.589 km 2 with 21 million people, region has 1.6 million agricultural establishments and 95% are classified as family farms. The typical agricultural systems are characterized by high grazing density, slash and burn practices, and fruits and legumes by irrigated monocultures. Consequently, soil degradation occurs due unsustainable soil management, decreasing soil carbon stock, and the biodiversity. The soil carbon depletion is also associated with saline, water, and thermal stresses. Saline, water, and thermal stresses in dryland, the impact of the land-use change associated with climate change, and few technological resources available for use in agricultural systems are the main reasons responsible for low productivity in the Brazilian semiarid region. Low-cost agricultural practices can contribute to build healthy and sustainable agroecosystems: among these, the selection of plant species tolerant to saline, water, and thermal stresses, the use of rhizobial inoculants, adoption of no-tillage, sowing green manure, and adoption of technologies to stock water to improve its efficiency and productivity.

Avaliação comparativa da qualidade de água de chuva e oriunda de açudes armazenadas em cisternas no semiárido do estado da Paraíba

As cisternas construídas para o armazenamento de água de chuva podem ser abastecidas com águas oriundas de açudes ou de rios, por meio de carros pipa. Isso ocorre pois as águas de chuva muitas vezes não são suficientes para suprir as necessidades das famílias em períodos de seca no semiárido brasileiro. Assim, o objetivo desse trabalho foi comparar 15 parâmetros de qualidade da água desses dois tipos, armazenadas em cisternas. Também foram feitas análises da variabilidade dos parâmetros e verificações de conformidade com base na Portaria do Ministério da Saúde no 05/2017. Foram realizadas análises físicas, químicas e microbiológicas no ano de 2017 em amostras de água de 12 cisternas, sendo 6 com águas de chuva e 6 com águas oriundas de açudes. Dos 15 parâmetros de qualidade da água analisados, 5 deles não apresentaram diferenças significativas entre as suas médias nas águas dos dois grupos de cisternas. Ademais, a água de chuva apresentou melhor qualidade do que a oriunda dos açudes.
