2-1. NBS（Nature Based Solution）

Nature-based Solutions (NBS) are defined by the International Union for Conservation of Nature (IUCN) as "actions to protect, sustainably manage, and restore natural and modified ecosystems that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits."[1].

The scope of societal challenges addressed by NBS includes climate change (adaptation and mitigation), disaster risk reduction, ecosystem degradation, biodiversity loss, food security, human health, economic development, and water security. While NBS can have a singular or multiple societal challenges as entry points, its evolution within that scope can potentially identify and address other specific issues.

NBS's impact has various estimated values, but it is said to provide about one-third of the cost-effective climate mitigation measures needed to achieve net-zero greenhouse gas emissions by 2050[2].

At SINRA, among the many solutions related to climate change, we will focus on the maintenance and regeneration of the natural environment, which has a significant impact and offers numerous accompanying benefits.
