Measurement of the aboveground biomass of some rangeland species using a digital nondestructive technique
Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of
canopy cover can now be easily and precisely made through image processing of high-resolution
digital photography. This study ...
The Relevance of Rest Periods in Rangeland Management for Plant Cover and Species Composition in Tataouine, Tunisia, Spring
In southern Tunisia, rangelands are overexploited because the animal needs highly exceed plant production. For most of the skeletal desert soil, the overall vegetation covering oscillates between 1 and 10%; the perennial ...
The Relevance of Rest Periods in Rangeland Management for Biomass Rehabilitation in Tataouine, Tunisia, Spring 2017
Field visits were carried out during March 2017 and allowed to identify and classify the sites subjected to rest according to the land tenure system and age of the implementation of the technique. During these visits, the ...
Revival of traditional best practices for rangeland restoration under climate change in the dry areas: A case study from Southern Tunisia
The purpose of this paper is to illustrate the benefits of reintroducing traditional grazing systems practices for improving arid rangelands. Grazing is the most extensive land use in southern Tunisia, but the rangelands ...
Response of arid rangelands to deferred grazing in Southern Tunisia
Rangelands in north Africa and the near east in general provide numerous goods and services that have great economic, social, cultural, and biological values. For centuries, inhabitants of rangelands have engineered pastoral ...
Enhancing sustainability and fodder production of lowland pastures through fencing and conservation agriculture in arid agro-pastoral ecosystems
The short-term fencing effects on vegetation in dryland landscape depressions are analyzed and the economic performance of grazing-only and integrated grazing with cropping in regard to land capital are compared. The goal ...
Modelling the Impact of Human and Climate Change on Stipa Tenacissima Distribution in the Arid and Semi-Arid Rangelands of North Africa
Rangelands in the Southern part of Tunisia are characterized by the extent of the impact of human
induced activities in particular overgrazing and encroachment of cultivation into best rangeland sites
(Ouled Belgacem et ...
Community based rangeland management in Tataouine, south east of Tunisia: Taking successes in land restoration (Gdel) to scale
ICARDA involvement under flagship 4 of CRP Livestock (on livestock and environment) is related to study of ecological practices and socioeconomic conditions that help for rangeland restoration under different land tenure ...
The Relevance of Rest Periods in Rangeland Management for Plant Density in Tataouine, Tunisia, Spring 2017
In southern Tunisia, rangelands are overexploited because the animal needs highly exceed plant production. For most of the skeletal desert soil, the overall vegetation covering oscillates between 1 and 10%; the perennial ...
Rangeland Biodiversity and Climate Variability: Supporting the Need for Flexible Grazing Management
Resting or grazing exclusion is an effective practice widely adopted to restore degraded, arid rangelands. To understand its effect on plant diversity, we studied Hill’s diversity indices during two growing seasons ...
