Challenges and opportunities of water quality monitoring and multi-stakeholder management in small islands: the case of Santa Cruz, Galápagos (Ecuador)

Abstract

Sustainable water resources management roots in monitoring data reliability and a full engagement of all institutions involved in the water sector. When competences and interests are overlapping, however, coordination may be difficult, thus hampering cooperative actions. This is the case of Santa Cruz Island (Galápagos, Ecuador). A comprehensive assessment on water quality data (physico-chemical parameters, major elements, trace elements and coliforms) collected since 1985 revealed the need of optimizing monitoring efforts to fill knowledge gaps and to better target decision-making processes. A Water Committee (Comité de la gestión del Agua) was established to foster the coordinated action among stakeholders and to pave the way for joint monitoring in the island that can optimize the efforts for water quality assessment and protection. Shared procedures for data collection, sample analysis, evaluation and data assessment by an open-access geodatabase were proposed and implemented for the first time as a prototype in order to improve accountability and outreach towards civil society and water users. The overall results reveal the high potential of a well-structured and effective joint monitoring approach within a complex, multi-stakeholder framework.

The impact of urbanization and domestic waste on a small watercourse in the eastern Amazon basin

“…Likewise, monitoring these parameters and, consequently, water quality is an important tool for understanding the impacts of urbanization on the environment (Re et al 2022). Indicating that the monitoring of water quality in urban rivers is considerable for the creation of pollution control measures, aiming at improving environmental quality and consequently the well-being of human populations (Silva et al 2022).…”

Water Quality from Natural Sources for Sustainable Agricultural Development Strategies: Galapagos, Ecuador

“…One of the main problems affecting the archipelago is the contamination of local freshwater resources, making them unsuitable for consumption and domestic use (mainly due to the presence of Escherichia Coli (E. coli) and Entamoeba histolica) [42,43]. On Santa Cruz Island, several researchers have been evaluating the water quality since 2007 [41,44,45], finding untreated wastewater discharges (increased amount of coliforms) as the leading causes of pollution, overexploitation of underground sources (causing saline pollution), and agricultural runoff (enrichment of water with nutrients and coliforms).…”

Sustainable environment: Road to educopolis and green city in the post covid-19 in Indonesia

“…Rizzi's study discusses sustainable water resource management through a case study on Santa Cruz Island (Galápagos, Ecuador). The results of this study describe that efforts to monitor the quality of clean water on an ongoing basis with accountable procedures and accurate data will help the public and water users to determine the quality of the water used [4]. The United Nations (UN) defines sustainability simply as "meeting the needs of the present without compromising the ability of future generations to meet their own needs" [5].…”
