Environmental monitoring is critical to develop appropriate policies for environmental sustainability. The quality of drinking and agricultural water is affected by bad environmental management strategies. In addition, natural water sources have been reduced due to climate changes and the lack of police and compliance with regulations for water resources management. In the Andes region of Ecuador, these problems have increased in recent decades. The lack of water affects not only human well-being, but also causes soil degradation. Therefore, finding alternative water sources has become the underlying requirement to provide human well-being and mitigate soil degradation in these regions. This article presents a fog collection system based on water condensation towers and Internet of Things (IoT) technology with real-time monitoring. Our system allows monitoring of environmental parameters while providing alternative sources of water from the environmental fog. Therefore, by collecting information related to the process of fog collection and climatic measurements of the environment, we seek to determine the state and trends of environmental conditions with respect to the performance of fog collection. In addition, our system allows the storage of historical environmental data, which can be used to develop environmental management policies. We have deployed our system on the slopes of the Ilalo volcano, Pichincha province, being part of the Ecuadorian Andes, where the soil deterioration has increased in recent years and has the largest soil degradation rate in Ecuador

Abstract.: Fog catchers have been successfully applied in several countries around the world. In Ecuador, the Galte communities in the Andean region suffer from water deficits because they are located at an altitude higher than 3500 m above sea level. Rainfall in the area is relatively low, about 600 mm per year, with high evapotranspiration of approximately 615.74 mm per year. This study aimed to install fog catchers in Galte in 2014 and 2015 to help meet the communities’ water needs. The fog catcher system was designed to satisfy the irrigation water demand for local agricultural production, mainly maize, based on estimates using the Blaney-Criddle method. Every day throughout the year, each fog catcher collected 5 to 20 L of water per m² of catcher area. The results indicate that the fog catcher system can meet about 5% of the local water demand for agricultural production. Keywords: Ecuador, Evaporation, Evapotranspiration, Precipitation, Water deficit.

The lack of water is a fundamental issue for survival of peasant communities located at heights above 3200 masl in the Andean highlands, such as in the case of the Galte-Yaguachi community in central Ecuador. The social balance, agricultural development as well as animal subsistence and finally the economic income is pending on the availability of hydric resources. Therefore, a three-dimensional fog collector system was constructed with Urku Yaku material in order to provide water for the close-by community. Simultaneously, we determined the quality of the collected water per square meter of the mesh, during the period of the highest annual precipitations. The installed nets yielded a gain of at least 2.63 L/m² and a minimum of 0.65 L/m² per day. The analyzed water quality reflected the suitability for human consumption. As water collection has been successful, an expansion of the proposed system may provide this fundamental good also to other communities with similar characteristics. Fog catcher towers will produce 26,577.84 m³/year of water, fulfilling crops’ needs, and the economic analysis proves it is worth the investment, as demonstrated by a benefit cost ratio of 1.90.

Bio-fermentation has been routed as a viable alternative for the treatment of organic waste, which can provide renewable energy and can return nutrients to the soil with its byproducts. In this context, the objectives of the research were to analyze the benefits that a plastic plug-flow bio-digester can provide for treatment of bovine manure; and through bio-fermentation to control the E. coli number present in the bio-digester effluents.
