Co$ting Nature V3 is a web based policy-support tool for natural capital accounting and analysis of the ecosystem services provided by natural environments. The focus is on costing nature (understanding the resource, e.g. the land area, and the opportunity cost of protecting nature to produce ecosystem services) as opposed to valuing nature (i.e. how much someone is willing to pay for it), though the tool does support economic valuation and has the necessary tools for this. The tool estimates the current provision of 18 ecosystem services including Timber (softwood, hardwood), Fuelwood (softwood, hardwood), Grazing/fodder, non-wood forest products, water provisioning (quantity, quality), fish catch, carbon, natural hazard mitigation (flood, drought, landslide, coastal inundation), culture-based tourism, nature-based tourism services, environmental and aesthetic quality services, wildlife services (pollination, pest control), wildlife dis-services (crop raiding, pests) and identifies the beneficiaries, then analyses current human pressures on the land, future threats and levels of biodiversity. It derives conservation priority from these factors. Users can then apply scenarios for land-use or land management change, and examine the impacts on ecosystem services and the implications for beneficiaries. The tool can be used to assess the impacts of human interventions for conservation prioritisation and planning. It also calculated Nature's contributions to the Sustainable Development Goals (SDGs).
