Lycium depressum L. is the only native tree-like life-form species inhabited in saline and alkaline regions of Turkmen Sahra located at Golestan province in Northern Iran. During past years, efforts have been made to increase vegetation cover of the area by cultivation of L. depressum L. to reduce water and wind erosions and dust storm […]
One of the fundamental difficulties in Iranian rangelands is the existence of wide area of poor condition rangelands that their grazing capability is low due to continuous livestock grazing pressure. Astragalus flexilipes is one of the palatable plant species of rangelands in Iran, while its distribution is being decreased due to improper grazing. The aim […]
Bush encroachment leads to land degradation in semiarid to arid regions. Over 45 million hectares of agricultural land in Namibia are affected. This is worrisome as nearly 70% of the Namibian population depends on agricultural activities and the beef industry is the mainstay of the farming communities. This study employed secondary data sources to provide […]
Nigeria is one of the most malnourished and hunger ridden in the league of developing countries; according to reports of Food and Agricultural Organization (FAO) of United Nations estimated daily animal protein intake for developing countries averaged at 4.5 g/head/day at the beginning of this century which has hardly risen to 10 g/head/day into the […]
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 […]
This study was conducted to evaluate the effect of copper extraction on the structure and function of rangelands ecosystem around the mine area in Dareh Zereshk, Yazd province, Iran. Three study sites were considered at the specified intervals of the mine (0-200, 200-500 and 500-1000m). This research was conducted from 2012 to 2013. In each […]
Salsola turcomanica (Litv) is a widespread wild plant species in Middle Eastern arid and semi-arid areas and is a relatively palatable halophyte species that has low establishment rate in the field. In winter 2017, in order to optimize the germination indices, its seeds were treated by scarification, stratification, scarification after stratification, gibberellic acid, potassium nitrate […]
This research aims to analysis the biophysical characteristics of watershed of Deli River to know potential flooding in Medan. The research is conducted at Deli River, which is located in 3 locations in North Sumatera namely Karo Regency, Deli Serdang and Medan City. Indonesia. This research used field survey method, survey activity in the form […]
Quantitative study of species diversity across different land use units and districts is important to document status of local plant biodiversity, to evaluate impact of management and for planning future management. This study aimed at determining impacts of land use units on species diversity and spatial distribution of species in two districts of Borana zone, […]
Hedysarum flexuosum L. is an important forage legume with high nutritive value. The determination of forage production in natural habitats is the most important factor for grazing management. Studies on its habitat characteristics and distribution are scarce. This research was conducted in order to evaluate the extent of pheno-morphological diversity in natural populations of Hedysarum […]
Food security covers aspects at all spatial levels from local to global and from an interdisciplinary and systemic food systems perspective. This book aims to better understand environmental, nutritional, agricultural, demographic, socioeconomic, political, technological, and institutional drivers, costs, and outcomes of current and future food security. Interactions with contextual factors include climate change, urbanization, greening […]
