Is long-term protection useful for the regeneration of disturbed plant communities in dry areas?
In dry areas, natural plant communities are mainly affected by climatic stress and human disturbances – overgrazing, ploughing and biomass harvesting – that accelerate their degradation. Management techniques, including ...
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 ...
Rangeland Monitoring & Assessment Training Workshop
The aim of the training course is building capacity of the Engineers and technical staff involved in rangeland management and development from Office of Livestock and Pastures (OEP), Commissariat Régional au Développement ...
Silvopastoral Systems and Climate Change Mitigation in Central Tunisia
The work is presented in North American Agroforestry conference: Agroforestry for sustainable Production and Resilience Landscape. 16th AFTA Biennial Conference on June 24-27, 2019 at Oregon State University in Corvallis, ...
Effect of protection on plant community dynamics in the Mediterranean arid zone of southern Tunisia: a case study from Bou Hedma national park
Ecosystems protected from heavy grazing impacts, such as national parks and refuges, are generally considered to sustain higher plant species diversity and better ecosystem composition and structure compared to heavily ...
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 ...
Silvopastoral Systems and Climate Change Mitigation in Central Tunisia
Livestock farming is part of rural community’s culture and is crucial for human well-being and livelihood. However, absence of desirable forages, lack of diversification and reduced livestock mobility have led to reduced ...
The vulnerability of native rangeland plant species to global climate change in the West Asia and North African regions
This study aimed to evaluate the impact of climate change on the geographical
distribution of selected native species from two areas from West Asia and North Africa.
Three species representing two genera were selected for ...
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 ...
Challenges and opportunities for promoting use of native species for the rehabilitation of degraded silvopastoral systems in Tunisia
On September 18, 2023, the One CGIAR initiative on Livestock and Climate, in collaboration with the Direction General des Forets (DGF) and the International Center for Agricultural Research in the Dry Areas (ICARDA), hosted ...
