Climate change and degradation of natural resources pose daunting challenges in arid and semi-arid rangelands of southern Mediterranean region. Overcoming these challenges requires considerable management actions efforts. In this context, the current...

The study investigated the e_ect of soil volume restriction on the below- and above-ground growth of Opuntia ficus-indica through understanding the limit imposed by root confinement via di_erent soil volumes on root and canopy architecture and growth...

Climate change poses a significant threat to agroecosystems, especially in the dry areas, characterized by abrupt precipitation pattern and frequent drought events. Ideal crops, tolerant to these events, such as cactus, can perform well under such...

Direct seeding techniques often result in unsatisfactory outcomes in rangeland rehabilitation, primarily because of low seedling emergence and poor establishment. Seed processing techniques aimed at improving seedling emergence have gained interest...

The objective of this study was to investigate farmers' adoption of sulla (Hedysarum coronarium L.) cultivation in northern Tunisia. Sulla adoption at farmer level and farmers‟ perception about the role of sulla were investigated through a survey of...

Livestock production in arid and semi-arid regions is facing the challenges of low and erratic rainfall, poor nutrient soils, and high temperatures, which all contribute to inadequate forage production to support livestock. Under these challenging...

Despite the importance of fodder shrubs to small ruminant diets and production in arid and semiarid ecosystems, they are often not considered when quantifying grazing land potential. This oversight is mainly due to the time consuming and costly...

The nutritive value of opuntia [(Opuntia ficus-indica (L.) Mill.] in combination with conventional fodders was assessed on 32 adult sheep, divided into 4 equal groups. The experimental diets consisted of chopped (5-8 cm) green opuntia cladodes (150 g...

Controlled grazing is considered a good management strategy to maintain or increase the live weight of livestock and to reduce vegetation degradation of rangelands. The present study investigated soil characteristics, aboveground vegetation biomass...

Seedlings of Artemisia herba-alba grown in glasshouse were watered with differing salinities (0, 150, 250 or 350 mM NaCI) and watering frequencies of 3, 7, 14 or 21 days for a period of 6 weeks. At the end of the study, plant survival, dry matter...

Proper soil preparation provides the basis for good seed
germination and establishment of steppe vegetation in
the arid and semi-arid areas of West Asia and North
Africa. Salsola vermiculata is a key shrub species of the
region and contributes to...

Digital elevation models (DEM) can be used to derive a wealth of information about land surface morphology. When analyzed using GIS information about stream channels and watersheds it can determine the flow of water over the Earth’s surface...
