Integrating Agroecology and One Health: A Path to Sustainable Food Systems and Improved Health por Tebourbi, Ons, Frija, Aymen, Alary, Veronique, Idoudi, Zied, Mannai, Amal, Rekik, Mourad

“…Agroecology is increasingly gaining importance around the world, including in Tunisia: It is defined as a holistic approach to redesign food systems in the purpose of concurrently achieving ecological, economic, and social sustainability. In this paper, we argue that principles behind the agroecological transition of food systems can be fully aligned with the holistic approach of One Health, and we provide an early conceptualization for that. …”

Climate change impacts on hydrology, upstream water dependencies and crop production in the Asian Mega-Deltas por Biemans, Hester, de Miguel Garcia, Angel, Gülpen, Marijn, Islam, Feroz, van Scheltinga, Catharien Terwisscha, Nelson, Katherine, Mondal, Manoranjan, Urfels, Anton

“…Both basins have sufficient water availability to meet full irrigation demands, excluding other sectoral and ecological needs now and in the future. However, during the dry season, the simulated agricultural water withdrawal in the deltas suppose an important part of the water inflows, making clear that deltas’ inflows during the dry season in both basins are highly sensitive to upstream irrigation abstractions, which are already substantial and projected to remain so by 2050. …”
