In 2011, the Grassland Ecological Conservation Subsidy and Reward Policy (GECSRP) was implemented in China. The purpose of implementing policy to protect grassland ecosystems, secure supply livestock products, increase income herders. Through quantitative research data collection methods, based on analysis comparison effects GECSRP before after its implementation 2011 ecology, production, herde...

Land use and land cover change (LULCC) is the result of both natural socio-economic determinants. The aim this study was to model determinant factors changes in Raya Valley, Southern Tigray, Ethiopia. Multistage sampling used collect data from 246 households sampled lowlands (47), midlands (104), highlands (93), sub-alpine (2) agro-climatological zone. Descriptive statistics logit regression we...

The Maghreb’s Mediterranean coastal edge is home to many peatlands with boreal floristic affinities and high conservation value. This work aims at investigating the Holocene developmental history of these wetlands in Northern Morocco, based on pollen record, loss-on-ignition radiocarbon dating. First, comparison between modern spectra present-day hydrophytic vegetation makes it possible identif...

A better understanding of the evolution vegetation cover is a major concern for countries where mountain ecosystems are undergoing severe degradation. Mediterranean woodland in general and those Algeria particular, suffering from numerous types degradation, be they climatic or anthropogenic. For this reason, to have issue how deal with it, we decided carry out study Aures Mountains (eastern Alg...

Watershed management is the study of relevant characteristics a watershed aimed at use and sustainable forests, land, water. Watersheds can be threatened by deforestation, uncontrolled logging, changes in farming systems, overgrazing, road track construction, pollution, invasion exotic plants. This article describes procedure to automatically monitor river basins Galicia, Spain, using five-band...

Individual traits such as body mass can serve early warning signals of changes in the fitness prospects animal populations facing environmental impacts. Here, taking advantage a 19-yr monitoring, we assessed how individual, population, and factors modulate long-term Canarian Egyptian vultures. vulture increased when primary productivity was highly variable, but decreased years with high abundan...

This paper investigates the hydrological interactions in the atmosphere-evegetation-soil system by using the bucket model and several new simplified intermediately complex models. The results of mathematical analysis and numerical simulations show that these models, despite their simplicity, can very clearly reveal the essential features of the rather complex hydrological system of atmosphere-e...

Although protected areas can lead to recovery of overharvested species, it is much less clear whether the return of certain predator species or a diversity of predator species can lead to re-establishment of important top-down forces that regulate whole ecosystems. Here we report that the algal recovery in a Mediterranean Marine Protected Area did not derive from the increase in the traditional...

Overgrazing has been the primary cause of grassland degradation in the semi-arid grasslands of the agro-pastoral transition zone in northern China. However, there has been little evidence regarding grazing intensity impacts on vegetation change and soil C and N dynamics in this region. This paper reports the effects of four grazing intensities namely un-grazed (UG), lightly grazed (LG), moderat...
