  • 3. Strategy for implementation the UNCCD in Belarus CHAPTER 3. Main Goals and Framework of the Strategy • unconditional implementation of the paid land use principle, improve the regulative function of and tax and rent, promote efficient and environmentally sound land use, improve the system of efficient goal-oriented use of payments for land with the aim of protecting and improving the land, develop a system of compensatory payments, etc.

  • 9. Capacity for renaturalization of degraded peatlandsNear 300,000 ha – natural mire with disruption of hydrological regime Drained peatlands emit about 3,751,700 Natural peatlands sink tons CO2 annually about 1,388,600 CO2 tons (exept fires) annually
  • 10. Estimation of the general economic value of lands (on case of study of peatlands of Belarus)The general economic value of peatlands included market cost of those resources which theyhave and also cost of the non-material benefits presented by them and services which society canuse. Such approach is the most perspective, and calculation is conducted on the followingformula : TEV= UV+ NUV,where TEV – quantity of total economic value; UV - the cost, equal to the value: DUV + IUV +OV - use value; DUV - direct use value (size of direct cost of use of resources of nature object);IUV - indirect use value (the indirect cost of the use of assimilation (reducing) functions of thenature object); OV – option value (the cost of the postponed alternative as the possible use ofresources and assimilation functions of nature object in the future); NUV - nоn-use value isdetermined by the total quantity, equal EV + BV (existence value + bequest value). The size of costof non-use of natural object (NUV), as a rule, is defined by cost of existence (EV), i.e. recreationalability of nature object, or the cost of heritage (BV) reflecting first of all social aspects of theimportance of natural object for society as a whole.
  • 11. Estimation of the general economic value of lands (on case of study of peatlands of Belarus)Cost of the indirect use of peatlands, which characterizes obtaining possible income from the CO2sequestration.If to take into consideration that on 1 hectare of the area of peat lands as a result ofphotosynthesis of bog vegetation the mass of the connected carbon, according to expertestimates, annually makes 3.6 tons, the lump of fixed carbon from the area of 312,600 hectareswill make 1,125,360 tons. In the conversion to СO2 the given quantity will be 4,079,430(1,125,360 • 3,625) tons. According to available data the price of 1 t of carbon dioxide in theEuropean market makes 13.2 US $. Therefore, the total cost of annually connected carbon canmake 53,848,000 US $, and taking into account time factor (the norm of discount equal to 10 %)in 33,087,000 US $. The cost of water-regulated and other functions of the peatlands isestimated approximately, proceeding from their total area (312,600 ha) and the price of filteringability of 1 hectare equal to 265 US $.It comprises: on the net income 82,839,000 US $ and to the net discounted income 50,900,000US $. Thus, cost of direct and indirect use of peatlands of Belarus of nature protection will make:on the net income 142,399,000 US $ and to the clean discounted income 87,497,000 US $ per 1year.
  • 12. Policy oriented recommendationsThe cost assessment of lands provides the successful solution ofimportant problems:• an assessment of level and rates of exhaustion or reproduction of soil resources;• the determination of the influence of the processes of land resources use on the pattern of utilization of other nature and anthropogenic resources;• effectively regulation nature-conservation policy for purposes of sustainable development of separate territories and to decrease economic damage from the degradation of lands;• analyze of the motion of the flow of money in the interrelation of land resources and economic development.
