The present study is a part of the CNPQ project no. 521477/96-4, which is being carried in the semi-arid region (lower part of the higher Piranhas) of the state of Paraíba in northeastern Brazil. The ...
ESTIMATION OF FOREST STAND PARAMETERS IN DENSITY CLASSES IN ARID AND SEMI-ARID REGIONS USING LANDSAT ETM+ DATA.
Landsat ETM+ data from the National Park of Khabr in Kerman province, dating May 2000, were analyzed to investigate the possibility of forest type mapping in arid and semi-arid regions.Quality evalu...
Numerous tanks were constructed and used for irrigation purposes in southern India. With the advent of canal and ground water system of irrigation, they were neglected and found to be in non-usabl...
Vegetation indices that provide important key to predict amount vegetation in forest such as percentage vegetation cover, aboveground biomass, and leaf-area index. Arid and semi-arid areas are not exe...
This study proposes a new drought index based on several precipitation-based parameters to quantify drought hazard in semi arid region. In addition to the practice of using only rainfall volume for in...
In the study an attempt is made at deciding the best agricultural land use in a study area located in the western part of the Nile Delta in Egypt. The area covers approximately 14,194 hectares and co...
Precipitation is one of the most important factors which can determine the type and productivity of rangeland vegetation in arid and semi arid regions. In the present study, a widely used drought anal...
In this study, Zanjan from Iran has been chosen from among all the semi-arid regions of world, which has Synoptic station and statistical data since 1955. Spring and monthly precipitations are also pr...
Nitrogen is the major limiting nutrient in crop production and it is also one of the nutrients that is easily lost from the plant-soil system in various ways. Due to this, N supply, N management and N...
The interaction between vegetation and hydrologic processes is particularly tight in water-limited environments where a positive-feedback links soil moisture and vegetation. The vegetation of these sy...
