Abstract
Land use change has transformed a vast part of the natural landscapes of the developing world for the last 50 years. Land is a fundamental factor of production and through much of the course of human history; it has been tightly coupled with economic growth. Bare soil has recently increased and it is one of the most important land degradation processes in the Mediterranean basins. The land use has changed rapidly within and near Neka River which is a fast growing agricultural river Basin. The land use changes in this region were analyzed based on Landsat data from 1977 to 2001. Supervised/unsupervised classi?cation approach coupled with GIS analyses was employed to generate the change over land use/cover maps. In order to analyze landscape fragmentation, land-use change has been calculated using NDVI. Based on the results of the analysis, the range of NDVI has changed from 0.9597/-0.2876 in 1977 to 0.6420/-0.187 in 2001 which shows that bare land has increased, while woodland areas decreased.
Highlights
In developing countries where a large proportion of human population depends almost entirely on natural resources for their livelihoods, resulting in land-use and cover changes
The objectives of this study are to provide a recent perspective for land cover types and land cover changes that have taken place in the last 24 years; to integrate visual interpretation with supervised and unsupervised classification using Remote sensing; to examine the capabilities of integrating remote sensing and GIS in studying the spatial distribution of different lands and to assess the land affected by soil erosion and the barren land
The result of normalized difference vegetation index (NDVI) has ranged from +0.9597 to 0.2876 and +0.6420 to 0.187 in 1977 and 2001 respectively
Summary
In developing countries where a large proportion of human population depends almost entirely on natural resources for their livelihoods, resulting in land-use and cover changes. The exports of timber to Romania had taken a leap forward and there was a need for the application of quick and speedy production and exploitation of natural resources. It was at this time that the introduction of tractors and the use of machines in cutting trees were introduced in Iran. The rate of percolation has diminished, leading to the gushing of water into the Neka valley causing floods It is in this context that the present study will aim to analyze the change in the forest area for a period of 25 years
