Recent international recognition of indigenous peoples, their rights and contributions to solving current challenges has directed academic attention to the way research is conducted in relation to them, what topics are studied, by whom, and using which methodologies. The Mapuche are the most numerous indigenous peoples in South America and have ancestrally inhabited a territory denominated Wallmapu. This study undertook a comprehensive revision and meta-analysis of the scientific literature related to the Mapuche and Wallmapu. Through quantification and visualization of the scientific landscape, the goal was to enhance the understanding of the themes and patterns that have guided research in this field of study. We found 1611 documents in Web of Science and SciELO collections published between 1975 and 2020. Using CiteSpace software, we analyzed the main conceptual hotspots, identified central authors and pivotal works, among other aspects of the scientific knowledge domain. The main research themes found revolve around political and historical aspects of the relationship between Mapuche and the State; ethnobotanical research including plant properties and cultural knowledge transmission; and the indisputable connection between indigenous resistance and environmental depredation. We argue that valuing cultural diversity paves the road for reclaiming indigenous knowledge as a contribution to our understanding of the world.

Climate change scenarios predict alarming levels of water scarcity and damaging flood events worldwide. Considering hydric systems in integrated spatial planning will be crucial in mitigating, adapting, and reversing climate change’s catastrophic effects. This paper focuses on fluvial restoration as part of urban and territorial regulatory frameworks in the Andalién River and the city of Concepción in Chile. We consider three work scales: (i) basin, (ii) river reaches which focus on the city–river interplay, and (iii) site-specific, deepening the discussion around the last two. The objective is to elaborate an interdisciplinary dialogue between urban design, fluvial dynamics, and the Chilean regulatory framework where property rights play a predominant role in the management of natural resources (water and land). In this regard, the ‘New Latin American Constitutionalism’ offers concrete possibilities to operationalize an emerging paradigm that recognizes legal personhood for Nature. The incorporation of an ecological function to property rights emerges as a new way in which the principles of resilient urban development can be applied in order to combine river dynamics and urban growth.

Chile is currently facing a mega-drought, which is expected to lead to a significant increase in the water stress level. Social conflicts related to water use are linked to the effects of climate change and a governance system marked by the privatization of the natural resources of public interest. This study aims to analyze whether the current Chilean water governance scheme can adapt to the effects of climate change through a critical observation of the role of the River Vigilance Committees (RVCs; private user organizations exercising the public function of water management), from the perspective of Ostrom’s design principles for long-enduring Common-pool Resource (CPR) institutions. We analyze legal approaches, management mechanisms, and decision-making processes under the socio-climatic conditions that the country is currently facing. The results indicate that, with a few exceptions, the Chilean governance system does not allow RVCs to effectively incorporate the design principles—and, therefore, to achieve adaptation—due to dispersed functions, the exclusion of water users, and a lack of planning at different levels. We propose that water governance should consider the creation of River Basin Boards with broader planning powers, as well as the incorporation of different relevant stakeholders.

We describe how the water commons agenda has been mobilized by different social groups of Chilean society, including water social movements and indigenous people, and the way it was included in the constitutional debate (2021–2022). Although the draft for the new Constitution was rejected in September 2022, we argue that the water commons agenda is still being mobilized as a socioenvironmental project for the 21st century. Simply put, the water commons agenda does not disappear with the defeat of the proposed new Constitution. It continues to challenge the neoliberalization of nature and water imposed during the Pinochet dictatorship, proposing to create new ways to sustain the territories of life.

This paper reviews international and domestic normative and jurisprudential sources of the last twenty years on the Human Right to Water (HRW), focusing the study on Latin American countries that do not have this right expressly enshrined in their constitutional texts, especially Colombia, Argentina, Brazil, and Chile. It analyzes the arguments used in its recognition, the elements of its structure, and the ways of addressing the problem of entitlement and enforceable duties. The conclusion shows a stage of jurisprudential progress in the first two countries (Colombia and Argentina), with a recognition of various contents of the DHA in accordance with international standards, while in the case of Brazil and Chile there is evidence, with nuances, of a limited recognition. In this regard, the internal normative structures differ in terms of the role of the State and individuals in water management, and the judicial tools for the protection of fundamental rights as a way of processing conflicts over access to water.
