NbS Triple Win Toolkit: Biodiversity Indicators in Context 50 Table 2. SDG targets47 that the proposed indicators could provide information on. For some targets, proposed indicators are directly relevant for understanding progress towards at least one aspect of the target (Yes), and for others the proposed indicators could provide some information depending on the projects carried out and the ability to disaggregate data (Possible). Marine systems are currently not well represented inthe data from which the threatened species indicator is calculated but potentially could be applied in future as Red List coverage improves SDG Target Target Detail Hectares of ecological restoration Improvement in conservation statusof threatened species 6 6.6 By 2020, protect and restore water-related ecosystems, including mountains, forests,wetlands, rivers, aquifers and lakes Yes Possible 14 14.1 By 2025, prevent and significantly reduce marine pollution of all kinds, in particularfrom land-based activities, including marine debris and nutrient pollution Possible Possible 14 14.2 By 2020, sustainably manage and protect marine and coastal ecosystems to avoidsignificant adverse impacts, including by strengthening their resilience, and takeaction for their restoration in order to achieve healthy and productive oceans Yes Possible 14 14.4 By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics No Possible 15 15.1 By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements Yes Possible 15 15.2 By 2020, promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally Yes Possible 15 15.3 By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation neutral world Yes Possible 15 15.4 By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development Possible Yes 15 15.5 Take urgent and significant action to reduce the degradation of natural habitats, halt the lossof biodiversity and, by 2020, protect and prevent the extinction of threatened species Yes Yes 15 15.7 Take urgent action to end poaching and trafficking of protected species of flora and faunaand address both demand and supply of illegal wildlife products Possible Possible 15 15.8 By 2020, introduce measures to prevent the introduction and significantly reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species Possible Possible
