Modelling NDVI from decadal rainfall data in the North East Arid Zone of Nigeria

Article Abstract:

The decadal rainfall over the preceding seven months can help predict Normalized Difference Vegetation Index (NDVI) in the North East Zone of Nigeria through satellite imagery. The NDVI is a tool for monitoring vegetation growth and deciphering changes in vegetation consequent to decadal rainfall data in a particular region. The model for computing NDVI is independent of location and annual rainfall and can be extended to record NDVI data prior to the period of satellite imagery. The model also explains the inter-seasonal and intra-seasonal differentials in NDVI.

The stewardship of arid Australia: ecology and landscape management

Article Abstract:

Australia's past land use policies have failed to arrest degradation and species loss in the country's arid and semi-arid lands. Rising concerns over these environmental damages has spurred research on developing more effective land use and biodiversity management strategies. A new approach to land management, which takes into consideration the needs of cattle raisers and the collective need for regional conservation, has been developed. A discussion of the key components of this approach is presented.

Simulation of vegetation dynamics and management strategies on south Texas, semi-arid rangeland

Article Abstract:

A model designed to stimulate seasonal dynamics of warm and cool season grasses and forbs, and the dynamics of woody plant succession through five seral stages, in each of nine different plant communities on the Rob and Bessie Welder Wildlife Refuge (WWR) is described. The model is designed to investigate the effects of alternative livestock grazing programs and brush control practices, with particular emphasis on prescribed burning, the preferred treatment for brush on the WWR.
