Grassland/rangelands based livestock production systems: Options and trade-offs between productivity and GHG emissions reductions
The global warming is expected to further contribute to the process of rangeland degradation as a result of mis-management and may have significant adverse impacts on range species under high CO2 emissions scenarios. Already ...
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 ...
Managing rangelands: promoting sustainable legume species: Hedysarum coronarium L.: a biennial herbaceous legume used for forage in the Mediterranean basin
Sulla (Hedysarum coronarium L.) is deep rooted and drought resistant. This species native to the Mediterranean is effective in biological fixation of sloping land, and improving organo-mineral soil fertility and yields and ...
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 ...
Managing rangelands: promoting and establishing endangered species: Rhus tripartita (Ucria) Grande: a rare and endangered species with great ecological value
Rhus tripartita is distributed in isolated populations within areas that have an altitude of 10–500 m and receive 100–600 mm of rainfall each year. It is usually found on calcareous soils, but it can grow in a variety of ...
Managing rangelands: promoting native shrub species: Rhanterium suaveolens Desf: a keystone species critical to rangeland structure and functioning
Rhanterium suaveolens is a desert plant endemic to North Africa and is best developed in parts of the sandy plains of the northern Sahara characterized by deep sierozem soils. Due to their attractiveness for various human ...
Managing rangelands: promoting and establishing sand dune fixing species: Stipagrostis pungens (Desf.) De Winter: a xerophytic quicksand- and dune-fixing species adapted to sandy deserts
Stipagrostis pungens is a perennial grass species which belongs to the Poaceae family. It is usually found with several erect culms, grows up to 1.5 m in height, and forms substantial tufts. It is a tall stiff glabrous ...
Rangeland restoration and management in relation to land tenure and vegetation type: the revival of the resting “Gdel” technique in southern Tunisia
Even if preliminary results have shown that a protection period of 3 years is not sufficient for disappeared species to appear nor for succession to reach a next stage, mainly in the degraded Stipa tenacissima community, ...
