In a global context marked by profound environmental, climatic, and socio-economic disruptions, the preservation of aquatic and terrestrial ecosystems, along with the safeguarding of public health and food security, has become a major and interconnected challenge.

Natural ecosystems—whether marine, freshwater, or terrestrial—play a fundamental role in maintaining biodiversity, regulating the climate, producing food resources, and supporting human health. However, these ecosystems are increasingly threatened by overexploitation, pollution, expanding urbanization, and climate change.

Faced with these challenges, this congress aims to bring together researchers, decision-makers, professionals, development actors, farmers, fishers, and citizens to share knowledge, experiences, and innovations. The goal is to better understand the interactions between natural environments and food systems, identify sustainable solutions, and promote integrated governance that takes into account ecological balance, health imperatives, and the nutritional needs of populations.
