Critical Natural Assets
Dataset contains 8 of the 14 nature's contributions to people (NCP) critical natural asset layers. Critical natural assets are defined as the natural and semi-natural ecosystems that provide 90% of the total current magnitude of 14 types of nature''s contributions to people (NCP).Global locations of these critical natural assets were mapped at 2km resolution. The layers included in this dataset are: Coastal Protection expressed as a unitless index of the coastal risk reduced by habitat multiplied by the number of people within the protective distance of the habitat; Marine Fish Harvest expressed as metric tonnes of fish caught per sq km (of ocean) per year; Nature Access for Urban and Rural Populations expressed as the count of rural people within 10 km of natural and semi-natural habitat, or within 6 hours; Nitrogen Retention for Water Quality Regulation expressed as nitrogen retention on natural and semi-natural pixels multiplied by the number of people downstream of those pixels; Pollinator Habitat Sufficiency for Pollination-Dependent Crops expressed in terms of the average equivalent number of people fed by pollination-dependent crops; Sediment Retention for Water Quality Regulation expressed as sediment retention on natural and seminatural pixels multiplied by the number of people downstream of those pixels; Global Moisture Recycling expressed as a fraction of evapotranspiration from vegetation that is providing precipitation to rainfed productive lands; Vulnerable C expressed as Tonnes of carbon/ha (for terrestrial ecosystems and mangroves). The layers available here are the layers that can be redistributed. Layers that cannot be redistributed, but can be visualized in the paper, are: fodder production for livestock, timberwood production, fuelwood production, flood regulation, riverine fish catch, and coral reef tourism.
