Bulk tank milk from 28 dairy farms was sampled every second month for 2 yr to assess the effects of grassland management, production system and season on milk fatty acid (FA) composition, concentrations of fat-soluble vitamins, Se, and milk sensory quality. Grassland management varied in terms of time since establishment. Short-term grassland management (SG) was defined as establishment or rese...

Grassland fire is one of the most important disturbance factors of the natural ecosystem. Climate factors influence the occurrence and development of grassland fire. An analysis of the climate conditions of fire occurrence can form the basis for a study of the temporal and spatial variability of grassland fire. The purpose of this paper is to study the effects of monthly time scale climate fact...

Grassland plays a key role for the food security of China because of the large number of livestock raised in those areas. Thus, grassland degradation due to climate change and overgrazing is considered as one of the most severe environmental and economic threat for the future sustainable development of China. Photovoltaic water pumping systems for irrigation can play a fundamental role for the ...

About 25% of European livestock intake is based on permanent and sown grasslands. To fulfill rising demand for animal products, an intensification of livestock production may lead to an increased consumption of crop and compound feeds. In order to preserve an economically and environmentally sustainable agriculture, a more forage based livestock alimentation may be an advantage. However, beside...

Grassland is an important ecosystem; the spatiotemporal evolution trend of grassland and its impacts on climatic factors play irreplaceable role in maintaining regional sustainable development ecological balance. In this paper, based remote sensing images 1990, 2000, 2010, 2020, 3S technology, we use methods dynamic rate transfer matrix to analyze northern Songnen Plain (China). The method grey...

[1] In semi-arid areas, multiple equilibrium states of an ecosystem (e.g., grassland and desert) are found to coexist, and the transition from grassland to desert is often abrupt at the boundary. A simple ecosystem model is developed to provide the biophysical explanation of this phenomenon. The model has three variables: living biomass, wilted biomass, and soil wetness. The moisture index, whi...

Sub-Saharan Africa consists of 43 countries south of the Sahara (Figure 1). This area spans latitudes 13°N to 33°S with an average annual daytime temperature of 21 °C. The UV Index is often higher than 10 (extreme) and rarely drops below 7, except at high altitudes and towards the tip of South Africa in the winter months (June, July and August). The land varies from equatorial rainforest to dry...
