Cross-Chapter Box 12.2 in WGI AR6, 'Climate information for climate services', shows that users are widely distributed across civil society. Relevant users of climate services include humanitarian organisations , government offices , international agencies  and the private sector . Climate services currently exist at local, national, regional and international scales, at time scales which range from sub- seasonal to decadal and longer  and in a range of different sectors . Agriculture is the sector with the largest number of examples ; others include health , forestry , fisheries , disaster risk reduction  and water resources management . Evaluations of the extent to which climate services are accessed, used and deliver benefits to decision makers remain in an initial stage , though studies suggest that these contributions vary widely depending on context. A review of evaluation of weather and climate agricultural services in Africa, for instance, found that most farmers use climate services when they are available , but that on-farm outcomes varied, with some farmers experiencing yield losses and others gains upward of 60% . Other studies express concern that large climate service projects have run for decades at significant expense, without adequate evaluation .
