An analysis of terracettes in a region of Giant's Castle Game Reserve, KwaZulu-Natal Drakensberg, South Africa.
(1998)Terracettes are a widely occurring form of micro-relief found throughout regions displaying various climatic and environmental conditions. Much speculation surrounds the processes responsible for their formation and ... -
Designing and implementing a GIS-based cadastral database for land administration in the city of Asmara, Eritrea.
(2004)The knowledge and application of land information and GIS in Eritrea are very limited and as a result there is a shortage of sufficient, reliable, up-to-date and modem land information for decision-making. This study ... -
Estimating foliar and wood lignin concentrations, and leaf area index (LAI) of Eucalyptus clones in Zululand using hyperspectral imagery.
(2006)To produce high quality paper, lignin should be removed from the pulp. Quantification of lignin concentrations using standard wet chemistry is accurate but time consuming and costly, thus not appropriate for a large number ... -
Estimating leaf area index (LAI) of black wattle (Acacia mearnsii) using Landsat ETM+ satellite imagery.
(2003)Leaf area index (LAI) is an important variable in models that attempt to simulate carbon, nutrient, water and energy fluxes for forest ecosystems. LAI can be measured either directly (destructive sampling) or by using ... -
An investigation into estimating productivity, above ground biomass and leaf area index of Eucalyptus grandis using remotely sensed data and a process-based model.
(2007)South Africa depends largely on afforestation programs for its timber supplies due to the great demands for fiber and wood products. This has brought discomfort to other water users who have advocated that the effects of ... -
An investigation into land capability classification in Eritrea : the case study of Asmara city environs.
(2004)The problems of land resources degradation as a result of misuse of arable land for non agricultural development and lack of appropriate methods and guidelines for land resources assessment are currently evident in Eritrea. ... -
A land suitability evaluation for improved subsistence agriculture using GIS : the case study of Nkwezela, KwaZulu-Natal, South Africa.
(2007)Rural farmers in the Nkwezela Area, with an average family size of 10 people, face a number of problems. The crops that are predominantly cultivated in the area, for subsistence (maize, dry beans, sorghum, potatoes, ... -
Land suitability evaluation for rainfed agriculture using GIS : the case study of Weenen Nature Reserve, KwaZulu-Natal, South Africa.
(2003)Weenen Nature Reserve (WNR) has a long history of unwise land use that resulted in severe overgrazing and soil degradation. Since 1948 several soil conservation and reclamation programs have been undertaken to halt the ... -
Mapping potential soil erosion using rusle, remote sensing, and GIS : the case study of Weenen Game Reserve, KwaZulu-Natal.
(2004)Accelerated soil erosion is drawing a growing attention with the recognition that the rate of soil loss is too great to be met by soil formation rate. Weenen Game Reserve (WGR) is an area with an unfortunate history of ...
