Carbon sequestration is complicated but important at global scales.

People’s perceptions of their environment

in high mountain rangelands ultimately

affect the fragile ecosystems on which

they depend, and thus their welfare. This is

especially true in developing countries,

where the livelihoods of people living in such ecosystems depend on grazing

livestock. The present study, conducted in the central mountain region of Peru, used photographs and Q methodology to investigate the criteria and preferences that shepherds and local administrators apply in making

The study was conducted with the objectives of analyzing and developing Near Infrared Reflectance Spectroscopy (NIRS) equation for predicting nutritional value and mineral constituents of chickpea haulm, and to determine the relationship between fodder quality and agronomic traits of chickpea. The samples were collected from Akaki, Alem Tena, Chefe Donsa, Debre-zeit and Minjar field experimental sites of Debre zeit Agricultural Research Center and the laboratory work was conducted at Animal Nutrition laboratory of the International Livestock Research Institute (ILRI), Addis Ababa.

Presents results of studies on the utilization of agricultural by-products as livestock feeds in Africa. Discusses methods of estimating the nutritive value of fibre residues and feed legumes, feed intake and digestibility, prospects of utilizing urea-treated maize stover, agroindustrial by-products and the chemical analysis of feeds.

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 problems affecting the special vegetation index.
