The Amazon is located on the periphery of what is called a «global urbanization» process. However, the increase in the urban population and the adoption of an economic development model based on the extraction of natural resources are undeniable. These dynamics have made water become a scarce resource, despite of its physical availability. What role does water management play in the construction of territories nowadays? Concepts such as the hydro-social cycle, hydro-social network and water landscapes are applied in the city of Lamas (San Martin, Peru), allowing the understanding of existing hydro-social territories and the lack of sustainability linked to them. / La Amazonía está ubicada en la periferia de lo que muchos autores llaman un proceso de «urbanización mundial». Sin embargo, es innegable el aumento de la población que vive en ciudades y la adopción de un modelo de desarrollo económico basado en la extracción de recursos naturales. Estas dinámicas han convertido el agua en un recurso escaso, a pesar de pesar de que hay una gran disponibilidad física. ¿Qué rol cumple hoy la gestión del agua en la construcción de territorios? Conceptos como ciclo hidrosocial, red hidrosocial y paisajes del agua se aplican en la ciudad de Lamas (San Martín, Perú), permitiendo comprender los territorios hidrosociales existentes y la falta de sostenibilidad vinculada con estos.

Native to the world’s third-largest tropical rainforest, the indigenous people of West Papua, known as Papuan, have experienced substantial changes to their ecosystem over the last several decades, primarily to their water resources. As surface water has been a primary asset for drinking water consumption and their livelihoods for generations, the increase in pollution from expanding oil palm plantations impacts many lives. Receiving limited attention, disentangling this water injustice from power relations as a byproduct of the state-backed development, corporate-driven expansions, and consumer demand become pivotal to advocating for the indigenous community and their livelihoods. Therefore, this study explores integrating physical evidence of agricultural runoff from oil palm plantations and indigenous perceptions using hydro-social territories in a remote area in West Papua, Indonesia. Due to the lack of long-term investigations of the impact of water contamination in West Papua, a hydrological model will be used to assess the nature of the oil palm impact within the watershed. As deterioration in water quality is expected due to landscape changes, the indigenous perception of hydrological changes is crucial to determine how significant the impact is on local livelihoods. Semi-structured interviews will be used to study the perception of indigenous communities on water resources and threats of oil palm to their livelihood. The synthesis of those results will later be concluded using the hydro-social approach, involving a multi-scale analysis that includes Indonesian state and corporate actors through literature reviews from various sources (e.g., official documentation, corporate reports, and journals). This research will develop strategies to protect indigenous communities not yet impacted by large-scale changes in the watershed resulting from palm oil plantations.
