This research explores how a fragmented river management structure hinders comprehensive river revitalization and whether recent projects and new approaches applied in these regions (e.g. transdisciplinary approaches to river landscape conservation and the Sponge City program) can redefine people’s connection to rivers. Through the comprehensive analysis of several case studies, this research project aims to synthesize feasible approaches to improve Urban Human River Encounter Spaces (UHRES) in different urban settings and contribute to a co-management scheme. The UHRES approach, based on the principles of “River Culture”, conceptualizes social-ecological systems in human-river relations without promoting human domination.

In the global context of hydrosystem restoration, the available hydraulic and ecological engineering techniques are relatively well known. However, ‘social engineering’, i.e. finding ways to match the goals of citizens’ or NGO initiatives with government policies, remains a major bottleneck for restoration projects. This PhD research aims to identify a holistic eco-social approach to river restoration in the Global South. To this end, it explores the participatory initiative to regenerate 44 rivers and adjacent streams in the southern state of Kerala, India (part of the “Now let me flow” campaign) in cooperation with the local government. The thesis hypothesizes that the role dynamics between local governments and local communities can contribute to improved outcomes based on the principles of “River Culture”. The study will determine the roles played by these two actors and whether it has contributed to improving the human-river relationship. The results will be utilized to develop a guide for collaborative river management projects in the Global South.

Urban lakes can support high biodiversity and provide critical ecosystem services. This research focuses on urban lakes, which are classified as a type of ‘urban stagnant water’ (USWs), and their ecological and social aspects. It aims to identify the drivers of macroinvertebrate diversity in urban lakes and explore how the public perceives naturalness in such areas. The study of three urban lakes in Tours, France (Lakes Bretonnieres, Bergeonnerie, and Peupleraies), and one in Wuhan (Lake Donghu), China, provides evidence to contribute to the sustainable management of urban lakes that can simultaneously enhance aquatic biodiversity and improve the provision of ecosystem services. To that end, this research analyses how USWs can be strategically integrated into urban planning, designed, and maintained from an interdisciplinary vantage point in order to tackle the environmental and social challenges related to urban lakes. To support this study, an extensive review of the past and current status of USWs is undertaken to further our understanding of the ecological, social, and engineering aspects of USWs management.

PhD RESEARCH: Kinshasa, N’djili and Congo River, Congo

Kinshasa is the 3rd most populated city in Africa; it is located on the bank of the Congo River and has many urban rivers and a diversity of cultures linked to riverscapes. In the last 50 years, the city has witnessed exponential population growth and uncontrolled urban expansion. Due to the hydrography of the city, a large proportion of the population lives near an urban river, which has been affected by high levels of pollution from different sources and unplanned land occupation. For that matter, it is essential to study how the city has developed, in the past 50 years, environmental protection actions and its river culture. In order to understand how a fast-developed city like Kinshasa can regenerate its riverscape, this research analyses the current situation and investigates the applicability of the ‘River Culture’ concept in the local urban planning. Fundamental to this approach is to research how to learn from local cultural diversity and how this knowledge can contribute to mitigating the deterioration of the local riverscape.

MASTER’S RESEARCH: Magdalena River, Ciénaga de Zapatosa, Colombia

Ciénaga de Zapatosa is the largest continental marsh in Colombia. It derives from the Magdalena river basin and it’s largely supplied by the Magdalena and Cesar rivers. Located in a depression between two departments, Magdalena and Cesar, it accounts for 5 municipalities (Tamalameque, El Banco, Chiriguaná, Curumaní, and Chimichagua). In Chimichagua is located the two fieldwork sites involved in this research: Sempegua and La Mata. It has an average extension of 40.000 hectares, and it’s populated by fishing communities which amount to 150.000 inhabitants. Artisanal fishing, livestock raising, and game hunting are the main livelihood activities. Farming, instead, is limited to the dry season, when waters recede, and plots of land become available for cultivation.

Especially in the Magdalena catchment, wetlands are highly degraded by human activities, and so are the multitude of ecosystem services they deliver (Mitsch and Gosselink 2000; Ricuarte et a., 2017). Intensive cattle ranching, monocropping, mining, urban development, and construction of dikes led to wetland drainage, deforestation, extreme floods, land loss, drastic reduction of catches, and water contamination (Viloria J., 2008). This, in turn, had direct repercussions on the fishing communities living on the riverbanks of the Zapatosa, affecting their subsistence activities and resources. They suffer from food insecurity, poverty, and diseases due to poor sanitation and polluted water (Fundación ALMA, n.d.).

This research aims to investigate several aspects that could improve food security and economic stability in the fishing communities of Sempegua and La mata, in the Ciénaga de Zapatosa area of Colombia. Thereby it intends to contribute to both the need to diversify the diet of the local community and to introduce crops that can be processed and stored for the wet season, when the community relies solely on fishing.  Based on principles of agroecology, and an action research (AR) approach aimed at the co-creation of knowledge with the local community, this research will focus on studying ways to (1) introduce new endemic crops in the vegetable gardens; (2) identify and implement methods to preserve the local harvest; and (3) develop a tool to harvest uva de lata (corozo).

MASTER’S RESEARCH: Río Nagsiche, Ecuador

Following the National Water Law, both national and regional governments in Ecuador have set out to distribute water rights in a fixed liters/second allocation. Yet, in a country that is characterised by highly seasonal rainfall and flow patterns, this practice is increasingly seen to result in an overallocation of existing water resources. In the Nagsiche river basin, this overallocation presents periods of water scarcity, during which a myriad of actors scramble for access to water. While most of the water users have a formal right to extract water from the river, the opportunities to materialise these water rights are drying up. The institutionalised water scarcity along the Nagsiche river therefore results in tensions between the multitude of water right holders in the river’s territory and the existence of fictitious water rights, or agua de papel – water rights that exist on paper but do not result in actual water access in practice. The situation in the Nagsiche river basin reveals how power asymmetries between different water users open up a new realm of environmental injustices in Ecuador, where access to water has become a highly politicised subject.

This research aims to unravel the realities of water users that depend on the flow of the Nagsiche river in Ecuador. It aims to uncover the power dynamics that are encapsulated in the rules and regulations that determine water access along this river, and how both explicit and subtle rules of inclusion and exclusion influence the opportunities of various water users to materialise their water rights. Involving the water users along the Nagsiche river basin, the research aims to reproduce the stories of what it means for various actors to defend their water access and control in a waterscape that is filled with an increasingly wide variety of actors with highly divergent interests. The focus is specifically on the conflictive realities that are generated by the inconsistency in the opportunities for different actors to materialise their on-paper-rights, and how affected water users in the Nagsiche river basin would envision a more just waterscape.

MASTER’S RESEARCH: El Río Monjas, Quito, Ecuador

The belief that Nature should receive rights has been growing around the globe; being perceived to be a solution to Anthropos catastrophic activities, which are negatively affecting all other forms of life on the planet and beyond. However, research on the effects of such legal changes is lacking. In 2008, Ecuador has granted Rights to Nature. However, El Río San Pedro, one of the most important rivers running through the country’s capital, Quito, all the way to the Pacific, is one of the examples which experiences high levels of contamination. Thereby, negatively impacting all human and non-human life surrounding the river while increased urbanization is expected to further worsen the situation. Public concern over the river’s pollution have led to actions being taken for possible recovery processes of the river while contamination practices are ongoing. The roles of the various actors involved in these processes, such as neighbours of the rivers, the municipality, parish governments, citizen groups, peri-urban farmers and industries. There are several uses, and ways of valuing and relating to the river that are at stake and mediated by power relations that should begin to be explored.

Situated within the Rights of Nature framework, this research will focus on how power dynamics influence the lived experiences of citizens living next to the highly contaminated river, El Río San Pedro in Ecuador. This will be done through ethnographic research within the Anthropology of Water by combining the political ecology and political ontology lenses.

This study will investigate how the Rights of Nature are perceived and used by the different stakeholders involved, and what these rights do in practice; how El Río San Pedro is shaped and used as a subject. And what social, political, economic effects and conflicts arise from these rights. It will look at the different human-river relations by exploring the different cosmologies and ontologies of the actors involved; how, and as what the different actors relate to El Río San Pedro; besides, how social relations between the actors are shaped through the river. As the intensity of recovery processes varies per region, the last focus will be on the people living in the area which lacks protection and on a daily basis have to live in the ruins of environmental pollution. Therewith will be explored how this affects their thoughts, beliefs and actions which shape their hydrosocial lifeworlds.
