Anthropogenic pressure, contaminants and water resource in the Andean Altiplano (Bolivia): towards resilience strategies Water resources in the Andean Altiplano are being degraded in both quantity and quality by anthropogenic pressure and global change. Based on multidisciplinary projects co-constructed between scientists from Bolivia (UMSA) and from the IRD, the LMI ALTIPLANO will strengthen and develop research actions to understand the links between “Humans, Environment and Resources”. The research will focus on the study of anthropogenic (mining, agriculture and urban) practices and their impacts on access and quality of water resources and associated elemental contaminant issues. The development of surveillance and alert systems (remote and in situ sensing, biomonitoring), and mitigation or remediation strategies geoengineering, regulation, etc.) in association with local communities (participative science) will allow the development of resilience strategies for the sustainable management of Andean socio-ecosystems. The LMI will facilitate the involvement and training of early career Bolivian scientists on complex nexus subjects (Water resources, Mines, Environment, and health and socio-environment), respecting the objectives of parity.

Since 2018, The International Joint Laboratory BIO_INCA has gathered the expertise of dozens of colombian, Ecuadorian and French researchers to promote the emergence of an operational research and capacity building platform, specialized in integrative studies, from genomes to ecosystem services, of the natural and cultivated ecosystems of the Tropical Andes (see BIO_INCA report 2018-2022). Building on extensive interdisciplinary collaborations that have emerged over the last years, our team proposes to conduct a second phase of the LMI (2023-2027) during which our diverse array of research expertises, capacity building and transfer activities will converge on three model systems: the paramos (high altitude andean grasslands), forests (in particular palm socioecosystems and Yasuní), and crops (in particular the management of diseases, pests and pollinators and valuation of agrobiodiversity). To develop a scientific project in line with sustainability stakes of paramount importance in the three institutions the LMI will particularly support : 1) Problemcentered research projects that find their source in a confrontation with real-world issues (rather than in the dynamics of the scientific disciplines it mobilizes), and that allows a global understanding of the major development challenges. 2) Activities favoring interdisciplinarity (and inclusion of local communities), which is justified because the major issues of our society call for a both environmental and social viewpoints. 3) Activities favoring a multistakeholder co-construction, involving research actors and a wide range of actors in order to bring out issues related to the needs of society. Overall, the vision of the LMI BIO_INCA is to have built after 5 years, a research-based plateform on integrative sustainability research in socio-ecosystems of the tropical Andes, which supports a science that is the expression of both the creative independance of researchers and their responsibility with regard to societal issues.

Brazilian landscapes have undergone centuries of unwise use of biodiversity, water and other natural resources, causing severe environmental degradation and widespread social impacts across the country. Environmental degradation of most Brazilian landscapes has been aggravated by the ongoing expansion of agro-industry, livestock and mining with serious repercussions on the functioning of ecosystems. First, anthropogenic biodiversity loss due to the extinction of species and their ecological interactions threaten key ecosystem services, such as pollination, seed dispersal and nutrient cycling. Second soil degradation, including compaction, laterization, nutrient depletion and loss of organic matter imposes severe socioeconomic impacts on agriculture and inc and and reduction the availability and quality of water resources accentuated, for example, by the proliferation of hydroelectric dams, agricultural reservoirs, and the effects of deforestation on water security. Third, from a social standpoint, the anthropogenic degradation of landscapes and natural resources has a significant impact on indigenous peoples and small farmers whose ways of life are intimately linked to biologically diversified and functional ecosystems. This is particularly noticeable in the Nordeste region, which includes the most deprived semi-arid region of Brazil and highly threatened remains of the Atlantic Forest (the Pernambuco Endemism Center), where the development of the agricultural and energy sectors combined with climate change pose serious threats to biodiversity, water resources, and the wellbeing of populations. The impacts of climate changes and human activities on biodiversity, soils and water resources are numerous, complex, and distributed differently according to temporal and spatial scales. It remains very challenging to understand, assess and predict the interplay between eco-evolutionary and socioeconomic processes that shape the socio-ecological coviability of these territories, i.e., the multiple ways by which the functional and persistent interaction between humans and non-humans is viable (Barrière et al., 2019a). Understanding socio-ecological coviability from an interdisciplinary perspective and considering specific regulations and constraints is however crucial for the efficient governance of the territories with coviability strategies that effectively reconcile nature, societies, and economies.
