Rainfall Variability and Its Impact on Normalized Difference Vegetation Index in Arid and Semi-Arid Lands of Kenya
Semi-Arid NDVI Time Series Southeast Kenya
2013/3/6
Agriculture in arid and semi-arid lands of Kenya is depends on seasonal characteristics of rainfall. This study seeks to distinguish components of regional climate variability, especially El Niño...
Influences of Leaf Area Index estimations on water balance modeling in a Mediterranean semi-arid basin
Leaf Area Index estimations water balance modeling Mediterranean semi-arid basin
2009/12/8
In the present work, the role played by vegetation parameters, necessary to the hydrological distributed modeling, is investigated focusing on the correct use of remote sensing products for the evalua...
Biogeochemical factors contributing to enhanced carbon storage following afforestation of a semi-arid shrubland
Biogeochemical factors carbon storage following afforestation semi-arid shrubland
2010/1/14
Ecosystems in dry regions are generally low in productivity and carbon (C) storage. We report, however, large increases in C sequestration following afforestation of a semi-arid shrubland with Pinus h...
Interaction of water components in the semi-arid Huasco and Limarí river basins, North Central Chile
water components semi-arid Huasco Limarí river basins
2010/1/28
For sustainable water resource management in semi-arid regions, sound information is required about interactions between the different components of the water system: rain/snow precipitation, surface/...
Drivers of inter-annual variability in Net Ecosystem Exchange in a semi-arid savanna ecosystem,South Africa
inter-annual variability Net Ecosystem Exchange semi-arid savanna ecosystem
2010/1/19
Inter-annual variability in primary production and ecosystem respiration was explored using eddy-covariance data at a semi-arid savanna site in the Kruger Park, South Africa. New methods of extrapolat...
Soil biogenic emissions of nitric oxide from a semi-arid savanna in South Africa
Soil biogenic emissions nitric oxide semi-arid savanna South Africa
2010/1/18
Soils of arid and semi-arid ecosystems are important biogenic sources of atmospheric nitric oxide (NO), however, there is still a shortage of measurements from these systems. Here we present the resul...
A global comparison of four potential evapotranspiration equations and their relevance to stream flow modelling in semi-arid environments
global comparison potential evapotranspiration equations stream flow modelling
2010/1/28
This study compares four different potential evapotranspiration equations according to Priestley Taylor, Kimberly Penman, Penman Monteith (FAO-56) and Hargreaves on a global basis to demonstrate their...
Evaluation of evapotranspiration methods for model validation in a semi-arid watershed in northern China
evapotranspiration methods model validation a semi-arid watershed northern China
2010/1/27
This study evaluates the performance of four evapotranspiration methods (Priestley-Taylor, Penman-Monteith, Hargreaves and Makkink) of differing complexity in a semi-arid environment in north China. T...
What happens after the catchment caught the storm? Hydrological processes at the small, semi-arid Weatherley catchment, South-Africa
Hydrological processes the small, semi-arid Weatherley catchment
2010/1/22
The knowledge of water flow pathways and residence times in a catchment are essential for predicting the hydrological response to a rain storm event. Different experimental techniques are available to...
