Modeling grassland productivity through remote sensing products
Mixed grasslands in south Canada serve a variety of economic, environmental and ecological purposes. Numerical modeling has become a major method used to identify potential grassland ecosystem responses to environment changes and human activities. In recent years, the focus has been on process …

An analysis of long-term effects of climate change and socioeconomic activities on grassland productivity of inner Mongolia
… the long-term causal relationships between the grassland productivity, climate change, and socioeconomic development of Inner Mongolia Autonomous Region (IMAR) of China. Our attempt began with acquiring remotely sensed satellite imagery, climatic variations, and aggregated annual reports of the …

A grassland forage supply assessment in Southeast British Columbia with comparisons to current Rocky Mountain elk (Cervus canadensis nelsoni) and range cattle (Bos taurus) grazing pressure and analysis of productivity distinctions
Open grassland productivity was measured within adjacent East Kootenay range units to evaluate forage availability and calculate elk (Cervus canadensis nelsoni) and cattle (Bos taurus) sustainable carrying capacity targets. This research extends rangeland monitoring with an analysis of site …

Roles of grasslands in sustainable improvement of land productivity in Bukoba District, Tanzania
… soil fertility are predominant thus limiting the productivity of the land. In this farming system, grasslands form an integral part in land productivity. However, changes in land tenure systems particularly for grasslands in recent years have undermined the functionality of the agro-ecological …

Optimising carbon storage by land-management
… with the greatest control on SOC identified as grassland landmanagement. Other controls on SOC were: land-use, soil series, altitude, soil pH and landuse history, indicating that these should be used in all estimates of SOC distribution and stock. A possible link between phosphate fertilisation …

Development of mechanistic energy balance models for grassland
Grasslands are responsible for a significant percentage of the world's food supplies and, due to their large geographical extent, have an important influence on global climate. Major determinants of grassland productivity include near-surface soil and air temperatures and plant water use. Therefore …

Productivity, physiology, community dynamics, and ecological impacts of a grassland agro-ecosystem: integrating field studies and ecosystem modeling
Grasslands are among the largest ecosystems in the world and provide numerous ecosystem services. These services include the ecosystem benefits important in an agricultural context such as biomass production and benefits from an ecological perspective such as mitigation of greenhouse gas emissions. …
