LAND USE AND LAND DEGRADATION ISSUES IN THE CONTEXT OF THE UNESCO “MAN & BIOSPHERE” PROGRAMME
A brief historical overview of approaches to study the problem of land use and land degradation in the MAB UNESCO program is provided. Over the past 50 years these issues remain important although the general strategic approach to their research and solving has changed from a multilateral study of land management and land degradation in different geographic and socio-economic conditions with an emphasis on natural diversity, to practices and approaches of sustainable land management in biosphere reserves, as reflected in MAB Strategy (2015-2025) and Lima Action Plan (2016-2025). Many of the MAB initiatives in the field of sustainable land management and combating land degradation have been further reflected and revised in different international programs and conventions. The development of these approaches and the integration of the MAB program with other modern activities can significantly increase the effectiveness of the results of Strategic Direction “A” of the Lima Action Plan on the use of UNESCO Biosphere Reserves as models for sustainable development. Five objectives are proposed for closer cooperation of the MAB program and its network of biosphere reserves with other international and national measures for promoting sustainable land management practices and combating land degradation: 1) using biosphere reserves as priority sites and observatories for comparative assessments of indicators of land degradation neutrality (LDN) for protected areas and adjacent territories in similar bioclimatic conditions; 2) use of data obtained through the series of observations in the territory of protected areas as the most important additional or alternative indicators and measures for the LDN interpretation; 3) biosphere reserves as models for selecting effective solutions reflecting the triad of adaptive actions to avoid degradation, reduce the rate of degradation and restore previously degraded lands; 4) achieving LDN on the territory of biosphere reserves through the implementation of the Aichi biodiversity targets; 5) the use of LDN as a criterion for evaluating the effectiveness of the activities of biosphere reserves. Preliminary results of the LDN assessment for Central Chernozem State Natural Biosphere Reserve and Middle Volga Integrated Biosphere Reserve and their adjacent territories provided to demonstrate the possibility of performing some of the objectives listed.
