Abstract
ABSTRACT: The co-success of Sustainable Development Goals highlights more attention on farmland within PAs, which is a typical manifestation of the conflicts between biodiversity conservation and food security. Here we developed a trade-off framework concerning farmland sustainability and efficiency, and conducted farmland decisions under different scenarios. We estimated 1.26Mha farmland for de-farming and 0.55Mha for reservation under the strictest habitat protection scenario; 0.81 Mha farmland for de-farming and 0.80Mha for reservation under the laxest habitat protection scenario. Such trade-off decisions were anticipated to cost 0.92~2.32 million tons of crop production while increasing 19.22~24.38 billion CNY of ecological benefits for habitats. We also found more than a tenth of farmland units(0.33Mha) within PAs in terrible agricultural conditions and argued them firstly de-farming regardless of benefits. This framework integrating crop production and habitat protection could provide a propagable approach for farmland trade-offs in global PAs and valuable decision support for the win-win of different SDGs.
