Land Use Policy. 68:264-276
Land use change, climate change, and the politics of accelerated agricultural growth shape contemporary land use in Russia. This factor combination urgently calls for exploring viable opportunities for sustainable land management in rural areas, whic

We studied an improved slope form system using a fuzzy logic method to assess and map soil fertility of a mountain region in northern Vietnam that has strong relief conditions. The lack of good soil mapping techniques in Vietnam has brought about ins

Field Crops Research. 156:91-102
Maize ( Zea mays ) cropping has greatly increased in Southeast Asia since the mid-1990s, mainly by expanding its production into steep forested uplands. This led to severe erosion, soil degradation, and strong environmental impacts. This study aimed

In Vietnam as much as half of the total land area is already degraded by soil erosion and nutrient depletion. In particular, degradation due to deforestation is increasingly affecting mountainous areas in north-western Vietnam. The necessity to safeg

Sustainable Land Use and Rural Development in Southeast Asia: Innovations and Policies for Mountainous Areas ISBN: 9783642333767
Agriculture carried out in the mountainous areas of Southeast Asia is intensifying rapidly, driven as it is by economic growth, policy changes, the introduction of new technologies and population growth. Rice, the dominant crop, is giving way to a gr

Sustainable Land Use and Rural Development in Southeast Asia: Innovations and Policies for Mountainous Areas ISBN: 9783642333767
The information available in relation to soils in Southeast Asia’s (SEA) mountainous regions is still limited, and so our research tried to rectify this situation in two key ways. The first approach was to gather soil information in order to help d

At two different experimental sites soil water and nutrient regime in grassland ecosystems was studied. The results show that by a site-adapted fertilization according to the grass uptake nutrient (N) losses can be reduced. The results will be used a

An Hand von 50 Beobachtungen wird gezeigt, das die Ausbildung der perikavernosen Atelektase weitgehend an die reizbare Konstitution gebunden ist. Von dieser Feststellung her ergeben sich wichtige Beziehungen zu den neueren Anschauungen uber das Wesen
