The world community must take action to both investigate on Population, Economy and Ecosystem services (I.v. Gerasimchuk) 94 the problem and try to solve it. In recent years fundamental international (IPCC, 2007) and Russian (Assessment Report, 2008) works have been published, with detailed analyses of the reasons for and 6.1. social and Economic Choice of Climate Change adaptation Measures in the russian Context 94 scale of human impact on climate system as well as currently-observed effects and future forecasts.

Maintaining natural habitats for biodiversity 125 and this report should be considered as a step in that direction in the ASE. Many studies have already been conducted in the ecoregion about the problems of climate change. Despite the large quantity of 6.4. opportunities and Measures for Climate Change adaptation in the altai-sayan Ecoregion 128 fundamental research on climate change and its impact on the region, there are relatively few action- 6.4.1. The nexus between the ASE economic development plans and the required oriented studies focused on specially protected nature areas in the context of climate change. Among them climate change adaptation measures 128 we note the participation of the Katunsky Biosphere Reserve in the UNESCO/MAB – GLOCHAMOST 6.4.2.
