“…Then, with an artisanal and technical method and some trial and error, the knowledge of past generations was revived [68]. The implementation of tapes allowed desalination of disabled wells, recharging of the aquifer, and increasing volume to an adequate supply of water for the community [69].…”

Resilience has several meanings, among them the ability to overcome difficulty and return to the state of providing service, even if the initial conditions change. Assessing resilience in an ecosystem, or any system, requires a concise methodology with standard variables and parameters. The current challenge presented by coastal areas is focused on overcoming problems related to the water supply through correct management. This paper aims to evaluate the communal coastal aquifer system with a matrix for assessing water resilience based on indicators in the Sustainable Development Goals (SDGs) in a socio-hydrological framework and the four axes of development (political, social, environmental, and cultural), to promote the development of new strategies for water sustainability. The method is based on (i) political, economic, social, environmental, and even cultural aspects involved in sustainable water management and (ii) the groundwater resilience assessment method (GRAM) design. The GRAM is used for a quasi-quantitative assessment of the resilience in a communal coastal aquifer system. This method was applied to the Manglaralto community; the results show a highly resilient groundwater system (62.33/100 points). Representatives of the community have achieved appropriate use, management, and conservation of the water resource by applying water harvesting and other technical criteria. Hence, they have avoided aquifer overexploitation and provided water to the community.

“…Another danger is the contamination of sewage from the fishing industry, as well as the waste thrown into river tributaries, marsh areas and estuaries by the shrimp industry in the Playa Bruja sector, the tributaries and leachates of the EMBASUR company-Embase Sudamericano SA canning fish are thrown directly into the sea causing negative impacts to the coastal marine ecosystem [16].…”

In the north of the province of the Santa Elena province (Ecuador), the important rivers in the area are seasonal, that is, the surface water is intermittent without supplying the population throughout the year. Consequently, the coastal aquifers are managed and exploited by the communes of the sector through the Water Boards. The "Regional Board of the Olón Drinking Water System" (JRAPO, acronym in Spanish), through 7 wells that pump 15 hours a day, supplies water suitable for human consumption to the communities of Olón, Curia, San José, La Núñez and La Entrada. However, when it is beach season, the demand for water increases and at the same time the flow in the wells decreases, generating problems in the water supply to the community members. The objective of this work is to analyze community water management through the social organization of the JRAPO, the technical measures in the water wells and the management of the river with its intermittences for the supply of water to the population. The work methodology includes i) processing of general and specific information on the Olón river-aquifer system, the organization of the JRAPO with its legal framework, ii) geographical territorial scheme of the situation of the Olón basin, iii) analysis of data from the aquifer such as: number of wells, pumping, demand, production and recharge, iv) the interpretation of data and management guidelines that obtain the current supply covering the demand. The results presented allow us to know the average flow of the wells that is around 20 lt/s and the production based on the pumping of said wells. The water from the wells complies with the requirements of the "Ecuadorian Technical Standard" (NTE) for human consumption in the sector. In conclusion, the analysis of the water management carried out by the community representatives through JRAPO is successful and considers several sections: good community organization, technical component that includes the evolution of the water levels of wells, measurement of the physical parameters. chemicals, well pumping regimes and environmental measures in pursuit of sustainability.

The rescue of water sowing and harvesting, an ancestral technique, is becoming increasingly popular at the dawn of the 21st century, due to its practicality and efficiency, but above all due to the sustainability principles. Water management is the challenge of the century, given the population growth and the consequent increased demand for water and the anthropic actions that pollute it, with groundwater being an alternative to the problem, and water sowing and harvesting is presented as a solution in different areas of the regional geography. The present work aims to analyze the systems of Water Sowing and Harvesting (SyCA, by its acronym in Spanish) through the study of the different cases in Iberoamerica that configure a mechanism of cooperation and transfer of the rescue of these ancestral techniques. The methodology includes i) matrix of comparative analysis of SyCA techniques and their characteristics, ii) SWOT analysis of the SyCA rescue process through the participation of five international experts, iii) strategies for the sustainability of SyCA processes in Iberoamerican countries. Currently, there are many cases of SyCA in Iberoamerica presenting novel cases, worked by rural communities that have a sustainability approach.
