Introduction Choosing machinery and land investments are two of the most difficult decisions faced by farm managers. Since both machinery and land are typically the most valuable assets to the farm, the ability of the farm manager to properly select equipment and plan for land expansion is imperative for financial success of the business. When selecting machinery, land area is an important fact...

Along with its economic reform, China has experienced a rapid urbanization. This study mapped urban land expansion in China using high-resolution Landsat Thematic Mapper and Enhanced Thematic Mapper data of 1989/1990, 1995/1996 and 1999/2000 and analyzed its expansion modes and the driving forces underlying this process during 1990-2000. Our results show that China's urban land increased by 817...

This paper is a theoretical and empirical investigation into the impact of the structural adjustment program (SAP) on forest loss in Ghana between the period 1965–95, An optimal control model is used to derive estimable reduced form equations for forest loss, cocoa land, maize land and timber production, which are in turn functions of mainly input and output prices. Piecewise linear and switchi...

Urbanization can cause changes in carbon fluxes, which, in turn, impacts atmospheric carbon dioxide (CO2) concentrations and possibly global surface temperatures. Using the Atlanta, Georgia, region as a case study, this paper explores the impact of urban expansion from 1973 to 2002 on land–atmosphere carbon exchange. The major objectives were to estimate net ecosystem production (NEP) values fo...

The world is witnessing a dramatic shift of settlement pattern from rural to urban population, particularly in developing countries. The rapid Addis Ababa urbanization reflects this global phenomenon and the subsequent socio-economic and environmental impacts, are causing massive public uproar and political instability. The objective of this study was to use remotely sensed Landsat data to iden...
