Understanding the historical change of agricultural landscape patterns is the basis for promoting the sustainable development of cultivated land, as well as appropriate decision-making. In order to analyze spatio-temporal changes of cultivated land in Sanjiang Plain, from 1985–2015, Landsat Thematic Mapper (TM) and Operational Land Imager (OLI) were used to reconstruct satellite data of land us...

This paper summarises the general pattern of urban land-cover change in the Northeastern Illinois between 1972 and 1997 using Landsat acquired remotely sensed images. The region, centred by the city of Chicago, experienced dramatic land cover change in the past decades. Accompanying the redistribution of population and decentralisation of metropolitan functions are the tremendous growth and dev...

The Mid-eastern Inner Mongolia of China, a typical agro-pastoral transitional zone, has undergone rapid agricultural land use changes including land reclamation and cropland abandonment in past decades due to growing population and food demand, climatic variability, and land use policy such as the "Grain for Green" Project (GFG Project). It is significant to the regional ecology and sustainabil...

1. Ecosystem services to agriculture, such as pollination, rely on natural areas adjacent to farmland to support organisms that provide services. Native insect pollinators depend on natural or semi-natural land surrounding farms for nesting and alternative foraging resources. Despite interest in conserving pollinators through habitat restoration, the scale at which land use affects pollinators ...

The paper reviews agricultural development in Nigeria, in the context of the emerging technologies of Geoinformatics, specifically Remote Sensing, Geographic Information System (GIS) and Global Positioning System (GPS). It expounded on the principles of Geoinformatics and their relevance in agricultural development. A critical analysis of the prevailing situation in Nigeria reveals the shortcom...

Changing patterns and reduction in agricultural land are among the fundamental problems that impacts food security in developing regions like India. Rapid economic growth coupled with increasing populations and changes in climatic patterns are among the main factors impacting availability of agricultural land. On a macroscopic scale, due to the lack of good quality data, governments do not have...

This study spatially assesses, quantifies, and visualizes the agricultural expansion and land use intensification in the northwestern foothills of Mount Kenya over the last 30 years: processes triggered by population growth, and, more recently, by large-scale commercial investments. We made use of Google Earth Engine to access the USGS Landsat data archive and to generate cloud-free seasonal co...

Although the Netherlands is one of the most densely populated countries, two thirds of the land area are still under agricultural use. Major socio-economic changes are however expected for the agricultural sector. The increasing globalisation of economic relations in agriculture and the possible reduction of European price support to farmers are examples of such developments that may affect agr...

Agriculture began in the eastern Mediterranean Levantine Corridor about 11000 years ago toward the end of the Younger Dryas when aridity had diminished wild food resources. During the subsequent Climatic Optimum, agricultural villages spread rapidly but subsequent climatic changes on centennial to millennial scales resulted in striking oscillations in settlement, especially in marginal areas. N...
