Conference Paper

According to the statistical data of the National Scheme of Soil Conservation and Combating Desertification, the area affected by desertification in Algeria is estimated at 20 million hectares of stepperangelands. These steppes play a fundamental role in theagro-pastoral economy of the country. Unfortunately,these spaces are currently very threaten...
Conference Paper
Full-text available
The last four decades have been marked by the fight against desertification and the development of steppic ecosystems, which has become a national priority. In this context, several management techniques have been tested to cope with the advance of the desert. The purpose of this study is to highlight the effect of two management techniques (fencin...
Conference Paper
Full-text available
The rangelands of the Algerian high steppe plains cover a large area, about 20 million hectares, or 8.4% of the total area of the country. These steppes play a fundamental role in the agro-pastoral economy. Unfortunately, they are, currently, very threatened. For some decades, these ecosystems have been experiencing profound changes that are manife...

Cadmium (Cd) is one of the most notable heavy metals because of its high mobility and toxicity towards plants. In the present study, we aimed to evaluate the effect of cadmium on growth, physiological parameters, anatomical changes and phenolic compounds content in Phaseolus vulgaris L plant. Seedlings were exposed to cadmium at 0.25; 0.5 and 1 g.l...

Palatable exotic shrubs plantation in heav- ily degraded rangeland has been massively managed in arid and semi-arid Algeria. An associated effect observed to these managements is an increase of plant richness in these plantations due to positive interac- tions involving nurse species that ameliorate stressful environmental conditions. Our objective...

Fencing and planting: two restoration strategies for the improvement of vegetation, soil fertility and soil surface properties in Algerian arid rangelands. Description of the subject. The struggle against desertification and the implementation of consecutive steppic ecosystem protection plans have become a priority in Algeria over the last four dec...

Article
Description du sujet. Ces quatre dernières décennies ont été marquées par la lutte contre la désertification et la protection des écosystèmes steppiques, devenues des priorités en Algérie. Plusieurs modalités de restauration ont été retenues pour gérer, voire restaurer les parcours steppiques sensibles. Objectifs. L’étude menée vise à quantifier l’...
Conference Paper
Full-text available
The growing demographic pressure and motorization of stocks transport led to an increasing use efficiency of forage patches and thus faster overgrazing of these fragile systems. The degradation of steppes led the government to set up measures to protect the fertility of threatened ecosystems. One of solutions used was forage plantation of Atriplex...
Conference Paper
Full-text available
Steppes of arid Mediterranean zones are deeply threatened by desertification. To stop or alleviate ecological and economic problems associated with this desertification, management actions have been implemented since the last three decades. The struggle against desertification has become a national priority in many countries. In Algeria, several ma...

Les steppes d’alfa occupent une grande partie des zones arides du bassin méditerranéen occidental. Ces communautés végétales ont été utilisées par l’homme depuis des milliers d’années, aussi bien pour la collecte de l’alfa et l’utilisation de sa précieuse fibre, que pour le pâturage et beaucoup d’autres usages. Ainsi, ces écosystèmes ont constitué...
Conference Paper
Full-text available
This work is based on 335 phytosociological samples taken in alfa formations (Stipa tenacissima) of Algeria. The study was undertaken with two ecological levels: soils are considered through their type or their physicochemical characters. Our research aimed to detect edaphic variables and the ecological parameters that influence vegetation diversit...
Conference Paper
Full-text available
In the Algerian steppes overgrazing combined with dryness leads to degradation and loss of vegetation cover. To meet the growing needs of livestock, the government launched an operation to plant 1 million ha of Atriplex canescens. To determine the impact on floristic diversity of the plantation of this species a methodology was adopted based on the...
Article
Full-text available
The current state of the steppe rangelands came as a result of precarious environment constraints (climatic and edaphic aridity) and of an old and increasingly intense anthropic exploitation. To assess the pastoral production of the alfa steppes, a matrix of 183 groups and 499 species collected in all the Stipa tenacissima (alfa) formations of Alge...

Impact of grazing on biodiversity and soil surface state in five sites of the alfa steppe of Southern Algeria". In the context of biological diversity preservation, the biodiversity of some formations of Stipa tenacissima L., was studied at the floristic, botanic, biologic, phytochoric and utilitarian levels. The effect of grazing on floristic dive...
