Improving security of tenure over agricultural land has recently been the focus of a number of large land certification programs. While the main justification for these efforts was to increase productive investments and facilitate land rental transactions, we show that if access rights were tied to actual land use in the previous regime, these programs can also lead to increased outmigration fr...

This paper optimises projected land-use structure in 2020 with the goal of increasing terrestrial ecosystem carbon storage and simulates its spatial distribution using the CLUE-S model. We found the following: The total carbon densities of different land use types were woodland > water area > cultivated land > built-up land > grassland > shallows. Under the optimised land-use structure projecte...

The objective of this investigation was assessment of physical and chemical parameters ofsoil and sediment in loess lands under different land uses, in the north of Iran. A yearly soilsampling was carried out randomly in three land uses (cultivated, forest and pasture) inQarnave and Yelcheshme watersheds. Sediment samples were taken monthly in thewatersheds at the hydrometrical station of Tamer...

the present study aims to simulate the spatial pattern of land use change in lisar protected area,iran. land cover maps for 1989, 2000, and 2007 were depicted using tm, etm+, and irs liss-iii images ofthe area at stake. images were classified using a merge of unsupervised and supervised classification. camarkov model was used to predict land cover maps as a top-down approach in investigating la...

land use change of forest ecosystems in northern iran changes the soil quality of paresar (gilan province) and gorgan (gorgan province) regions. in order to study changes in some biological soil quality indices due to land use change from forest to cultivated lands, composite soil samples from two depths (0-20 and 20-40 cm) were taken from paresar and gorgan regions and urease, alkaline and aci...

As highland regions of Africa historically have been considered free of malaria, recent epidemics in these areas have raised concerns that high elevation malaria transmission may be increasing. Hypotheses about the reasons for this include changes in climate, land use and demographic patterns. We investigated the effect of land use change on malaria transmission in the south-western highlands o...

Topographic factors are essential to the spatial distribution of ridge orientation, yet literature shows limited exploration mechanisms underlying effects terrain on cultivated-land orientation in a black soil region. To better understand this subject, interpretation, statistical analyses and field verification were carried out Songnen Plain, typical Mollisol area. The results revealed that inc...

The transport characteristics of phosphorus in soil and the assessment of its environmental risk have become hot topics in the environmental and agricultural fields. The Sanjiang Plain is an important grain production base in China, and it is characterised by serious land use change caused by large-scale agricultural exploitation. Agricultural inputs and tillage management have destroyed the so...
