Rangeland utilization in Mediterranean farming systems

Animal, 2010
In the countries surrounding the Mediterranean basin, most of the semi-natural grazing lands are covered by rangelands. Rangelands can be defined as highly heterogeneous natural vegetation communities with high conservation value, growing in harsh ...

Botanical diversity as a reservoir of resilience: The emergence of new uses of wild plants under acute food shortages in Karamoja, Uganda

People and Nature, EarlyView.
Abstract Agro‐pastoralist communities in Karamoja, Uganda, face food insecurity driven by climate variability, declining livestock numbers and crop failures. In this context, local ethnobotanical knowledge systems play a central role in subsistence and adaptation.

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 ...

Complex causes and consequences of rangeland greening in South America – multiple interacting natural and anthropogenic drivers and simultaneous ecosystem degradation and recovery trends

, 2020
Land-surface greening has been reported globally over the past decades. While often seen to represent ecosystem recovery, the impacts on biodiversity and society can also be negative.

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.

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

Soil Properties and Plant Biomass Production in Natural Rangeland Management Systems

Revista Brasileira de Ciência do Solo
Improper management of rangelands can cause land degradation and reduce the economic efficiency of livestock activity. The aim of this study was to evaluate soil properties and quantify plant biomass production in four natural rangeland management ...

Influence of different grazing intensity on above-ground biomass in Mongolian rangeland

Proceedings of the Mongolian Academy of Sciences, 2019
In the last two decades, the quality of Mongolian rangeland has degraded primarily owing to overgrazing and climate change. This has government challenged to improve land usage and gather information about the tolerance of the rangeland.

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
