Aeolian desertification in Otindag Sandy Land has expanded dramatically during the past 50 years. This research explored processes and causes of aeolian desertification in the study area. The results showed that aeolian desertification development in Zhenglan Qi of typical region located at the center in the study area can be divided into three stages including rapid occurrence before 1987, parts of rehabilitation and most of deterioration from 1987 to 2000 and little rapid rehabilitation occurrence from 2000 to 2005, according to remote sensing images and field investigations.
Is it possible to have cheaper drugs and preserve the incentive to innovate? The benefits of privatizing the drug approval process
In this paper, we argue that lower prices for pharmaceuticals can be achieved by fostering a new type of competition in the pharmaceutical industry. Lower drug development costs, and hence prices, can be brought about by abolishing national drug administrations and replacing them with private certification boards that compete on the basis of safety, efficiency and cost of their drug approval process. A major benefit of this type of privatization is that it would not necessitate limits on data exclusivity in order to achieve lower prices.
Influence of Agricultural Land Use and Management on the Contents of Polycyclic Aromatic Hydrocarbons in Selected Silty Soils
The aim of the present study was the influence of various methods of long-term soil utilisation on the content of polycyclic aromatic hydrocarbons (PAH) in selected silty soils. Four soils were selected for the present studies, i.e.: Eutric Fluvisol originating from silty formations, Haplic Phaeozem developed from loess, Haplic Luvisol (non-uniform) developed from silt, Haplic Luvisol developed from loess. Five study sites were chosen, i.e.: apple orchards, hop gardens, fields, grasslands and natural woodland ecosystems. Samples were collected from the depth of 0-10 cm.
Adaptive Ecosocial System Sustainability Enhancement in Sub-Saharan Africa
A conceptual framework is developed and used for improving the livelihood of Sub-Saharan communities faced with multiple stresses resulting from adverse environments, vector-transmitted diseases, and limited food. Ecosocial systems are the units for management. The accumulation of ecological, economic, and social capital is the objective of management, the reduction of maintenance costs is the key strategy, and technologies must satisfy ecological, economic, and social criteria.
Integrated Ecological and Regional Planning in a Rapid-Growth Setting
Toronto is among the fastest-growing urban regions in North America. Regional efforts to preserve rural landscapes and remnant habitat have had variable success. In the 1990s, significant conflict emerged over proposals to build large housing developments on portions of the Oak Ridges Moraine, a 160-km stretch of environmentally sensitive land along the city's northern edge. After years of planning conflict, Ontario's provincial government created the Oak Ridges Moraine Conservation Plan, an Act of the Ontario Legislature.
