Property rights on genetic resources: economic issues

Biodiversity loss is one of the major international environmental problems. This paper analyses the question of how the use of genetic and biochemical resources in biotechnological industries might affect biodiversity conservation. It is argued that the answer will significantly depend on the concrete regimes of property rights on genetic resources and related biotechnological knowledge. One of the main conclusions derivable from this analysis is that a tightening of intellectual property rights may either aggravate biodiversity loss or strengthen biodiversity conservation, depending on various conditions. This result has interesting parallels to the results of second best theory. Furthermore it sheds new light on the debate regarding the relationship between the WTO Agreement on trade-related aspects of intellectual property rights (TRIPs) and biodiversity loss.     

Optimization of interpolation parameters when deriving DEM from contour lines

Digital elevation models (DEMs) are still an important and current source of information for digital soil mapping and the modeling of soil processes. The grid DEM is often interpolated from contour lines. The contour sampling step becomes an additional interpolation parameter which can play an important role. The objective of this paper is to optimize the interpolation parameters of the Regularized spline with tension (RST) method, in order to prepare a DEM suitable as an input for erosion modeling. Two contrasting cases, with and without a reference DEM, were investigated. If a reference DEM was available, good results of interpolation were reached both by small and larger sampling steps. In the second case, it was found that small sampling steps should be avoided. The influence of the sampling was demonstrated by topographic potential for erosion and deposition.

ОБЪЕКТИВНЫЙ ПРОГНОЗ АНОМАЛЬНЫХ УСЛОВИЙ ПОГОДЫ НА ТЕРИТОРИИ ЧСР С ИСПОЛЬЗОВАНИЕМ ЧИСЛЕННЫХ ПРОГНОЗОВ ПОЛЕЙ ДАВЛЕНИЯ И ТЕМПЕРАТУРЫ

Summary There is presented a method of classification of synoptic situations, which are characterized by heights of surfaces1000, 850 and500 mbar, temperatures at the surface850 mbar (eventually by moisture at the surface850 mbar) in 90 points of the square grid. Typical synoptic situations are defined with the respect to above-normal and sub-normal temperatures, above-normal number of fog and thunderstorms (summer and winter) on the territory of Czechoslovakia. The method of exploatation of typical synoptic situations for automated middle range forecast is described.
