Aim of study: The aim is to find a way increasing gain yield and lessen area of farmland, and then increasing vegetation cover, improving environment and alleviating soil erosion.Area of study: The Hilly-Gully region at the loess plateau of China.Material and methods: In this study, an adjusted and optimized land use pattern was developed in Luoyugou watershed in the Yellow River valley based on the gradient distribution of land use types, and its effect on water and sediment transport was simulated using the SWAT model and GIS, with remote sensing images, land use maps and hydrologic data.Main results: The results indicate: average simulated runoff and sediment for the period 1986-2000 under conditions of the three land use pattern (2011, 2008 and optimized land use) reduced by 0.002-0.013 m3/s (2.7-17.6%) and 0.66 million tons, respectively. The runoff and sediment data obtained were compared with observed data from 2008, which showed that runoff and sediment production would be reduced by 467625 m3 and 22754 tons, respectively.Research highlights: The adjustment of the land use pattern in comprehensive consideration of vegetation and geography have a positive effect on water and sediment transport which will be important for decision making and water resources management, and provides a reference for future environmental management and ecological construction in the loess plateau Hilly-Gully region.

Land-use cover is undergoing intense change under global climate change and rapid urbanization, especially in the Loess Plateau, where ecological restoration policies like Green for Grain Project (GFGP) have been vigorously implemented since the 1980s. The main objective of this study was to distinguish the difference of spatio-temporal variation of land-use change in the two study periods of 1980–2000 and 2000–2020 at the county scales. Geographically and temporally weighted regression (GTWR) was employed to handle both the spatial and temporal heterogeneity of the driving forces for land use change. The results showed that the quantity of construction land, woodland and grassland experienced continuous growth, but arable land declined substantially. The results of GTWR model showed that the dominant influencing factors of land-use change had temporal and spatial differences in the Loess Plateau. Specifically, the implementation of GFGP and precipitation accelerated the changes in arable land, grassland and woodland. For construction land, its growth was mainly promoted by gross domestic product (GDP) and population, both of which had more obvious positive effects in the last 20 years. The findings provide a scientific basis to put forward countermeasures emphasizing sustainable land use in the Loess Plateau.

Due to alterations in physiographic and social-economic conditions, climatic changes, adaptation and population growth, the land use pattern of Bangladesh is changing very rapidly. Bangladesh is a small country but it bears a huge population, resulting in a very high density of population and very high intensity of land and resource use. Per capita land is estimated to be only about 0.0526 ha. Two significantly prominent phenomena driving country’s overall scenario of economic development and environment imbalance include: (a) the high growth rate of population engulfing precious land for settlement and (b) scarcity of land for ever increasing demand of food. As a result, the land use pattern of the country is changing at a great momentum. Every year the country is losing 1% arable land due to the population growth and its infrastructure development. This study was conducted on Rajshahi District where the major focus was to see the land use pattern of the area, trend in the change of land uses, and in particular, challenges for the agricultural land. For analyses remotely sensed data (Landsat MSS-1977, TM-1990 and TM- 2010) and GIS techniques were used and secondary data were collected from SPARRSO, published and unpublished data regarding crop, population and other ambient information from mostly government sources. Results show that the land use pattern of Rajshahi District is changing, especially the agricultural land is decreasing in an alarming rate and now it is become more and more vulnerable. The agricultural land of the study area is losing 0.46% per year and the area under infrastructure use is increasing 5.86% per year. If this rate continues, the agricultural land will be totally eliminated within the next 217 years. DOI: http://dx.doi.org/10.3329/jles.v6i0.9724 JLES 2011 6: 69-74
