Journal Article 1988

Autor: Hiernaux, Pierre H.Y.

Evaluates relationship between NDVI (nomalized difference vegetation index) and above-ground biomass, between maximum NDVI and end-of-growing season biomass; and between the integral of the NDVI curve or NDVI increments overtime and actual biomass. Describes atmospheric interference and technical...

Journal Article 2004

Autor: Powell, J.M. Pearson, R.A. Hiernaux, Pierre H.Y.

Many semiarid regions of Sub-Saharan Africa (SSA) are experiencing vast increases in human population pressure and urbanization. These augment the demand for agricultural products and have led to the expansion, intensification, and often closer integration of crop and livestock production systems...

Report 2005

Autor: Fernández Rivera, S. Hiernaux, Pierre H.Y. Williams, Timothy O. Turner, M. Schlecht, E. Salla, A. Ayantunde, Augustine A. Sangare, M.

Growing pearl millet and cowpea in combination with raising ruminant livestock is widely practiced in the Sahel. In this farming system, livestock feeding depends mostly on rangeland, fallows and cropland grazing. Nutritional constraints to grazing ruminants stem primarily from feed scarcity and ...
