Grassland is the first land use in the agricultural areas (AA) of Europe, covering, with rangeland, 56 million ha (33% of AA in EU). Grasslands are characterized by multiple functions and values but one of the most important is forage production for ruminants. In the “grassland region” milk production is connected with grassland management and proper utilisation, whereas in other parts of Europ...

The desert locust remains a major threat to global food security. Control operations are crucial tool manage crisis; this research investigated the nature of control conducted between 2019–2021. Historical data on and were obtained from survey reports at FAO Locust Hub analysed with respect reports, land cover types, cropland/rangeland extent crop productivity data. We found that 16.1% grid cel...

Regardless the crop production, range and livestock management is unlikely to be possible. Considering the range production is essential for efficient and effective range management. This study aims to investigate the relationship between the rate of forage production and the effects of climate variables. For this purpose, forage yield of four range species including Artemisia sieberi, Scar...

recognition of rangeland species with the maximum efficiency and the minimum water usage is very important, since major parts of rangelands in iran are located in arid and semiarid climate. in addition, the rangeland improvement and management on the basis of transpiration rate of rangeland species in different climatic conditions has great importance. the goal of this research is comparison an...

Abstract. Over the past decades, range managers have devoted extensive efforts to conserve and restore rangelands and sustain their exploitation but these efforts are more focused on the classic sciences and the exploiters' knowledge and experience have been neglected in the process. Therefore, current study was done to deal with the prioritizing and comparing factors affecting rangeland exploi...

Abstract. Smallholder farming systems in southern Africa are characterized by low-input management and integrated livestock crop production. Low yields dry-season feed shortages common. To meet growing food demands, sustainable intensification (SI) of these is an important policy goal. While mixed crop–livestock may offer greater productivity, it implies trade-offs between supply, soil nutrient...

Selecting the appropriate rangeland improvement method is a challenging task for range managers because it requires consideration of  various criteria. This study was  aimed to evaluate various restoration and reclamation practices in the rangelands of Semirom-Isfahan using Multi-Criteria Decision Making (MCDM) methods. Grazing management, water point development, pit seeding, exclosure, water ...

The role of ungulate grazing in shaping rangeland ecosystems is well known relative to other important plant-animal interactions such as pollination, seed dispersal, granivory, and belowground herbivory. Successful rangeland revegetation may be enhanced by strategies that favor certain groups of animals and discourage others. Many perennial forbs and shrubs require animals for successful pollin...

The complexity of natural resource management is increasingly recognized and requires adaptive governance at multiple levels. It is particularly significant to explore the impacts of government interventions on the management practices of local communities and on target social-ecological systems. The Inner Mongolian rangeland was traditionally managed by indigenous people using their own instit...

Conservation policy often incentivizes managers of human-impacted areas to create landscape heterogeneity to maximize biodiversity. In rangeland, patchy disturbance regimes create landscape heterogeneity (patch contrast), but outcomes of heterogeneity-based management are rarely tested for a universal response. We analyzed four habitat variables – vegetation structure, plant functional group co...
