    Rivers are ecosystems that are constituted as indicators of environmental quality thanks to the different types of environmental, and socioeconomic services they offer. Due to the constant expansion of cities, the pollution of rivers is becoming increasingly critical, especially in those rivers that cross or are close to urban centers. In developing countries, such as Bolivia, rivers are an accessible and invaluable source of water for use and consumption, so preserving their quality is essential. There are numerous studies of the water quality of the Rocha River carried out by various institutions that verified the increase in contamination in the body of water. However, the vulnerability for populations and ecosystems have not yet been identified for the entire basin. This research compiled and crossed the available information on anthropogenic activities, water quality, and population distribution to expose the impact on water quality and thus identify vulnerable populations in critical sectors of the Rocha River basin. This study is the base for formulating mitigation actions in the identified areas, to reduce the risk to public health and ecosystems.

    Critical Analysis of Stakeholders in the Municipality of Tarija, Bolivia, in Search of Strategies for Adequate Water Governance to Implement Reverse Osmosis as an Alternative for Generating Safe Water for Its Inhabitants
    (Universidad Católica Boliviana "'San Pablo". Programa VLIR - UOS., 2023-09-04) Villena-Martínez, Esteban Manuel; Alvizuri Tintaya, Paola Andrea; Lo-Iacono-Ferreira, Vanesa Gladys; Lora-García, Jaime; Torregrosa López, Juan Ignacio; Sánchez Barrero, Lorena; Fernández, Alejandra Leigue; D’Abzac, Paul
    The accelerated deterioration of water quality in the city of Tarija, Bolivia, has caused several water sources in the Municipality of Tarija to be discontinued due to the presence of toxic contaminants. The current water purification systems that are used in Tarija do not guarantee the elimination of heavy metals; in addition, political and social interest conflicts are a serious problem in the execution of projects and new public investment alternatives, with these being the main problems found in the sector. Reverse osmosis (RO) water purification technologies are one of the most effective contemporary alternatives for the elimination of contaminants in water, such as heavy metals; however, their application and implementation in countries with little or no experience in this type of technology require acceptance and knowledge on behalf of the interested parties. Political and social conflicts between interested parties generate scenarios that affect hydrological planning. Analysis of the actors in the urban and municipal sphere of the city of Tarija, Bolivia, provides a case study for adequate water governance and enabled us to come to a consensus for the implementation of RO. The results show 23 fundamental actors in water management in the Municipality of Tarija, with local actors being those with the greatest influence and power in decision-making. Our analysis of social networks showed an important polarization in the power of decision makers, with municipalities and legislative entities being those that decide on public investments. The interested parties showed considerable interest in the application of RO as a technology that can provide definitive, short-term solutions to the problems of water stress and the water crisis in the Municipality of Tarija and its application in small towns with a high level of social and environmental vulnerability.
