“…While the impact of drought was out of this project's scope, this declaration brings forth the ubiquitous challenges posed by climate change. Drought may decrease the water quality at the source [43,44]; in this vein, further research is needed to study the adaptiveness or resilience of the relationships we found against this effect.…”

While access to drinking water has expanded worldwide, safely managed provision is still a challenge, and rural areas are specially underserved. To provide safe drinking water for these areas, water scholars and international organizations have advocated for community-based organizations or coproduction schemes. The literature often mentions that institutions and people play a key role in the provision of drinking water although the specific mechanisms through which they may affect the process of maintaining good quality water have not been reported yet. The article aims to fill this gap by providing a complex, local view on this process. In Chile, from 1960 onwards, the State has implemented cooperatives to provide for drinking water in rural and small-town areas under a coproduction scheme. In this scheme, the State provides the infrastructure, and the community is responsible for service provision. We analysed the water quality of six of these cooperatives and conducted interviews with water managers and leaders. Our research suggests that formal and informal relationships provide the links and motivation needed for the organizations continuous work. These results highlight how relevant it is to keep in mind the context and the public role of delivering safe drinking water.

“…Para muitos animais essa faixa é ideal, por exemplo, para a maioria das espécies de peixes o pH deve se situar numa faixa de 6,5 a 8,5, já que fora desta há um comprometimento no seu grau de atividade e no apetite. Os resultados de pH observados estão de acordo com Guerrero et al (2020), que identificaram valores de pH mais altos em períodos de secas. Ainda segundo os autores, em anos secos, todo o ciclo da água é afetado pela redução da recarga dos reservatórios.…”

O presente artigo buscou identificar e analisar os impactos sociais, econômicos e ambientais da seca de 2012-2014 no município de Taperoá-PB e o papel das ações de convivência nesse contexto. A identificação dos impactos foi realizada utilizando-se o método de listagem descritiva check-list, dados bibliográficos e documentais. Para analisar as variáveis socioeconômicas e as ações de convivência foram utilizados os mesmos materiais dos impactos, exceto o check-list. Os impactos continuaram porque faltou recursos financeiros para implantar programas e as políticas públicas de convivência não foram efetivas, só aparecendo com maior intensidade quando a região estava prejudicada pela seca. Para redução dos impactos é necessário aumentar o número de cisternas, principalmente a calçadão. É necessário também perfurar poços e construir açudes, além de fazer manutenção nos que estejam com capacidade reduzida ou desativados; construir barragens subterrâneas e tanques naturais; terminar e colocar em funcionamento a Transposição do Rio São Francisco; incentivar a gestão dos recursos hídricos, criar programas que visem o fortalecimento da agricultura familiar, incentivando a fenação, silagem, meliponicultura, apicultura, criação de animais e plantas adaptados à região, dentre muitos outros. The drought of 2012-2014 in the municipality of Taperoá-PB and the role of the coexistence actions in this context A B S T R A C TThe present article sought to identify and analyze the social, economic and environmental impacts of the drought of 2012-2014 in the municipality of Taperoá-PB and the role of the coexistence actions in this context. The identification of impacts was performed using the method of descriptive listing check-list, bibliographic and documentary data. To analyze the socioeconomic variables and of actions of living together were used same materials of the impacts, except the check-list. The impacts continued because they lack financial resources to implement programs and public coexistence policies were not effective, only appearing with greater intensity when the region was hampered by drought. To reduce the impacts is to increase the number of cisterns, especially the boardwalk. You also need to drill wells and build dams, in addition to maintenance on that are with reduced or deactivated capacity; building underground dams and natural ponds; finished and put into operation the Transposition of the São Francisco River; encourage the management of water resources, create programs aimed at strengthening family farming, encouraging haymaking, silage, meliponiculture, beekeeping and the husbandry of animals and plants adapted to the region.Keywords: impact; family farming; livestock.

“…For the near future, climate change, also, will play an important role in the hydrological components, causing an increase of evapotranspiration and a decrease of precipitation, percolation, surface flow, and groundwater recharge [49]. Therefore, climate change impacts agricultural production, influencing the quality and quantity of water available for irrigation [50].…”

Reclamation of treated wastewater is considered a viable option for reducing the agricultural and national water deficit, especially in Mediterranean-type and arid climatic conditions. Given that Chile is a country around 40% of whose territory is classified as semi-arid and desert and 20% as Mediterranean, with serious water scarcity problems, and which uses a great deal of the resource in agricultural irrigation, the present paper offers perspectives on the current state of treated wastewater reuse and considers challenges to improving the development of water reclamation for irrigation in Chile as a case study. The methods followed included a systematic literature review to answer two important questions: (a) What is the state of reclamation of treated wastewater for irrigation in Chile? and (b) What criteria/parameters determine the feasibility of reclaiming treated wastewater for irrigation in Chile? The results showed that Chile has been affected by climate change in a short time: a megadrought has occurred over the last ten years, increasing the necessity for the country to secure alternative water sources for irrigation. The country has advanced greatly in wastewater treatment coverage, achieving almost 100% in urban areas, with technologies that can produce quality water as a new water source for irrigation. However, the lack of regulations and limited frameworks could explain the low direct reuse at present—below 1% of total flow. Regarding challenges, the necessity of updates to Chile’s institutional and legal frameworks, besides the inclusion of rural communities and the study of emerging contaminants, will be discussed. By these means, it will be possible to more efficiently utilize recycled wastewater as a new source for irrigation in this country.
