Research on the land use of the coastal zone in the sea–land direction will not only reveal its land use distribution, but may also indicate the interactions between inland land use and the ocean through associations between inland land use and seaward land use indirectly. However, in the existing research, few have paid attention to the land use in sea–land direction, let alone the sequential ...
The rehabilitation of sandy desertified land in various dryland ecosystems by different management practices has a great potential to increase aggregate stability and improve soil quality. However, plants in general may have a different ability to sustain soil. The objective was to determine the effects of reclamation practices including Haloxylon ammodendron and Atriplex canescens plantation o...
Irrigated croplands in Central Asia are highly prone to land degradation due to their environmentally fragile physical settings and intensive agricultural practices. This study: (i) assesses the state of croplands in irrigated areas in northern Uzbekistan, based on the time series of MODIS-NDVI imagery; (ii) analyzes relationships between the identified trend of cropland degradation and soil qu...
The damaged environment is a global problem. It is more serious in China because of the cultivable land destroyed. So the agroecosystem reconstruction is the primary object in China. A case of reclamation planning in LiaoNing Province was studied in this paper. A large number of abandoned land sites have become an urgent task for the local government since farmland is so short in this area. The...
Large areas of land are needed to dispose of wastes produced by mining activities worldwide which poses a myriad of environmental hazards with regards to soil, water and air contamination. This is a problem, especially for a mining country like South Africa, where more than 1500 mines are registered which affects 0.2 million ha of land. Legislation in this country do, however, stipulate that di...
High landscape diversity is assumed to increase the number and level of ecosystem services. However, the interactions between ecosystem service provision, disturbance and landscape composition are poorly understood. Here we present a novel approach to include uncertainty in the optimization of land allocation for improving the provision of multiple ecosystem services. We refer to the rehabilita...
BACKGROUND Reflex excitability is increased in hemiplegic patients compared to healthy controls. One challenge of stroke rehabilitation is to decrease the effects of hyperreflexia, which may be possible with water immersion. Methods/Aims: The present study examined the effects of acute water immersion on electrically-evoked Hmax:Mmax ratios (a measure of reflex excitability) in 7 hyperreflexive...
Arresting land degradation in impoverished rural environments is a global priority. Restoration ecology provides a promising framework, but it will need to be modified when applied to a rural development setting. There is a need for increased understanding of social dynamics in land restoration, however few systematic studies exist. This paper explores the social factors influencing restoration...
