Abstract:

Nature-based Solutions (NbS), put forward in recent ten years but well aware more recently, is a cost-effective approach to address environmental and social-economic challenges human being is facing. With respective to climate change, NbS is a set of approaches for conservation, restoration and sustainable management of ecosystems to mitigate climate change, and to address impacts and challenges induced by climate changes on human beings and wildlife through services provided by ecosystems. These ecosystems include forest, cropland, grassland and wetland (coastal ecosystems), either natural or man-made. NbS is able to contribute 30 percent of mitigation targets set by Paris Agreement, and provide substantial environmental and social-economic co-benefits. However, NbS is not well paid attention in previous policies and actions including the Intended National Determinated Contribution (INDC) and funding flow into NbS for climate change is limited. To maximize the NbS potential, it is recommended to conduct researches on China’s NbS mitigation potential and its co-benefits, identify cost-effective priority NbS pathways, summarize domestic and oversea successful NbS cases, develop incentive policies for mainstreaming NbS, and to push for collaborative governance of multiple sectors.
