In this U.S. Geological Survey study of forest land cover across the conterminous U.S. (CONUS), specific proportions and rates of forest conversion to developed (urban) land were assessed on an ecoregional basis. The study period was divided into six time intervals between 1973 and 2011. Forest land cover was the source of 40% or more of the new urban land in 35 of the 84 ecoregions located wit...
S tatewide, values of average Indiana cropland increased by 14.2% in the year ending in June 1996, nearly double the 7.4% increase a year ago.

Increases of around 35% were registered in both the first and last third of this 9 year period. There was a lull in the upward trend during ...
Planning for land use development, protection of good quality agricultural land, land degradation management and many other resource management issues requires reliable land resource information. Enhanced Resource Assessment (ERA) techniques were employed to rapidly assess and predict soil and landscape attributes throughout Cooloola Shire in South East Queensland.

The Land Cover Map of Great Britain, in 1990 was a relatively simple pixel-based classification while the Land cover Map 2000 adopted an object-based approach. The objects, land p...
This paper examines the impact of a land reform in Viet Nam which gave households the power to exchange, transfer, lease, inherit and mortgage their land-use rights. We expect this change to increase the incentives as well as the ability to undertake long-term investments on the part of households. Our difference-in-differences estimation strategy takes advantage of the variation across provinc...
Land suitability analysis is a prerequisite to achieving optimum utilization of the available land resources. Lack of knowledge on best combination of factors that suit production of rice has contributed to the low production. The aim of this study was to develop a suitability map for rice crop based on physical and climatic factors of production using a Multi-Criteria Evaluation (MCE) & GIS ap...

This study uses panel data from 1,142 Kenya smallholder households over four survey periods to examine the determinants of participation in land rental markets and to quantify the impact of renting land on households’ crop income and total income. We find that land rental markets in Kenya enhance productivity and are equitable. The results are consistent across different estimation methods and ...
