A combined method for assessing ecological intensification in aquaculture systems
International audience To meet the challenges of producing more while lowering impacts on ecosystems, new farming systems have to be designed. To define development strategies, a multi-scale assessment method that estimates the tradeoff between human demand and natural services, as well generates co...

International audience To meet the challenges of producing more while lowering impacts on ecosystems, new farming systems have to be designed.
