The value of regeneration

People and Nature, EarlyView.
Abstract Millions of hectares of rangelands have been subject to degeneration through overgrazing, agricultural expansion, urbanisation and afforestation. Countering this, regeneration is a natural process whereby rangeland ecosystems revive themselves.

Evaluation of rangeland conditions through field survey and NDVI in semi-arid area of Dubluk district Southern Ethiopia

Discover Environment
Rangelands play a crucial role in Ethiopia’s rural economy, ecological biodiversity, and food security. However, their condition at the local level remains inadequately documented, limiting timely responses to degradation.

Short-Term Monitoring of Rangeland Forage Conditions with AVHRR Imagery [PDF]

Journal of Range Management, 2002
A study was conducted to determine the potential of using Advanced Very High Resolution Radiometer (AVHRR) imagery to monitor short-term changes in rangeland forage conditions on a regional scale. Forage biomass and nitrogen concentration were estimated at 6 study sites throughout a typical grazing season (April to October). Study sites were located in

Plant species are more important to bacterial community composition than seeding ratio in a pea‐canola intercropping system

PLANTS, PEOPLE, PLANET, EarlyView.
Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

The relative productivity index: Mapping human impacts on rangeland vegetation productivity with quantile regression forests

Ecological Indicators
Rangeland degradation is a persistent decline in the productivity of vegetation that supports wild or domestic herbivores. However, rangelands often exhibit highly variable climates and dynamic, resilient vegetation, making it difficult to discriminate ...

Ecological Insights from Spatial Pattern Analysis: Halocnemum strobilaceum and Climacoptera turcomanica in Golestan's Saline and Alkaline Rangelands [PDF]

Desert
Halophytes and other salt-tolerant plants in rangeland ecosystems play an important role in environmental protection and food security. The spatial point pattern analyses of these plants in arid and semi-arid areas provide valuable information about how ...

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Pathways for Value Chains to Strengthen Sustainable Development in Mountain Regions: A European Cross‐Case Analysis Based on Stakeholders' Perceptions

Sustainable Development, EarlyView.
ABSTRACT Mountain areas are hotspots of high natural and cultural value, but they face sustainability challenges. This research offers a quantitative cross‐case analysis of 21 case studies from mountain regions across 14 European countries, examining how local stakeholders perceive the contribution of mountain value chains to sustainable development ...

Evaporative Fraction as an Indicator of Moisture Condition and Water Stress Status in Semi-Arid Rangeland Ecosystems

Remote Sensing, 2014
Rangeland monitoring services require the capability to investigate vegetation condition and to assess biomass production, especially in areas where local livelihood depends on rangeland status.

Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

Sustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing
