Article
In order to estimate some equations of daily milk production from linear body measurements of 85 local lacting goats were used in the present study. The morphostructural parameters included body length, withers height, heart girth and hip height, the body weight and the daily milk were recorded weekly from from the 7th postpartum day up to the end...

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 is to suggest efficient strategic choices and more profitable land allocation of lowlands in dry areas. To analyze the vegetatio...

The e-workshop consists of a keynote plenary session and four thematic sessions that address the connections between pastoralism and sustainable development: (1) environment, ecology and ecosystem services; (2) society and culture; (3) economy and finance; and (4) policy, institutions and governance. The keynote speeches addressed trends and challe...

The degradation of arid rangelands is mainly caused by overgrazing. Fencing is considered as a key management aspect to restore these ecosystems leading to changes in vegetation and soil structure. However, it depends on intensity and duration of protection. The aim of this study was to evaluate the impact of long-term fencing (more than 25 years)...

Sustainability 2021, 13, 7124. https:// Abstract: Resting or grazing exclusion is an effective practice widely adopted to restore degraded, arid rangelands. To understand its eff...
Article
Long-term protection of arid ecosystems changes the vegetation and soil structures. The quantification of aboveground biomass and carbon content are among the principal indicators to evaluate these changes. Most methods used to quantify these parameters are costly, time consuming and destructive. In this paper, two non-destructive methods were comp...

Purpose 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 have suffered many decades of severe degradation due to profound socioeconomic changes and the emergence of an agro-pasto...
Article
Full-text available
In recent decades, pre-Saharian Tunisian consequences of desertification have gradually become a major environmental problem. We are witnessing the continuous degradation of natural vegetation, due to various human activities. These activities often lead to overgrazing, due to the decline in the size of the course (after cultivation) and increased...
Article
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 aims to determine rapid, accurate and non-destructive ecological measurements of the aboveground biomass of selected plant speci...

Actual physiognomy of natural vegetation communities in southern Tunisia results from long dynamic during many decades. Besides the influence of climatic instability, human pressure greatly amplified the degradation process of the vegetation cover. This study aims to show the evolution of the natural vegetation in the governorate of Medenine betwee...

The restoration technique importance resides on the assessment of its impact on biodiversity. This assessment is possible by the use of some environmental indicators extracted from a diachronic study of land cover changes in protected areas. Our study is carried out with the evaluation of some indicators inside Sidi Toui national park. These indica...

La zone présaharienne de la Tunisie est caractérisée par des conditions climatiques très contraignantes à la survie des végétaux (pluviométrie très faible et très irrégulière, températures élevées, évapotranspiration très intense…). Cependant certaines zones bio-géomorphologiques gardent encore des conditions plus ou moins favorables à l'existence...
Article
Water points provide excellent sites for studying overgrazing effects on plant communities in dry areas. Distance from water can be considered like a surrogate of grazing pressure being high near the water and low away from it. The main aim of this study is to investigate overgrazing effects on acceptability of fodder plants along a grazing gradien...
Article
In Tunisia, Artemisia herba-alba Asso. is a very common steppe species of the natural rangelands. It is also well known as an aromatic and medicinal species. In spite of its adaptation to the difficult ecological conditions (xeric soils, aridity⋯), the natural habitats of Artemisia in Tunisia have obviously regressed these last years due to its ove...
Conference Paper
Full-text available
Grazing of the first year reseeded rangelands by palatable species is often proscribed. However, total protection may often lead to persistent weed problems and is hard to accept by land users keen to graze reseeded land as soon as possible. The present study aims at testing the case of reseeding arid Mediterranean cereal fallows with native palata...

The present study deals with the assessment of the effects of drought on the natural plant cover of two natural regions of Southern Tunisia. Several parameters and indicators have been used to describe the evolution of plant communities and their fate under the different constraints and disturbances effect. The main achieved results show that relat...
