Especially in Tajikistan, where the natural resource base is declining, the 2030 Agenda emphasizes its conservation, for which conscientious reporting frameworks (SDG 12.6) can help monitor progress. Economic productivity (SDG 8.2) depends on fresh water-use efficiency (SDG 6.4), which is enhanced by capacity-building support for water harvesting, desalination, recycling and waste-water treatments (SDG 6.a). Improving water-use efficiency (SDG 6.4) also feeds back into reduced water pollution and sustainable wastewater management (SDG 6.3).
