Explore the soil factors driving soil microbial community and structure in Songnen alkaline salt degraded grassland

Frontiers in Plant Science, 2023
IntroductionSaline-alkali degradation in grassland significantly affects plant community composition and soil physical and chemical properties. However, it remains unclear whether different degradation gradients affect soil microbial community and the ...

Holistic management – a critical review of Allan Savory’s grazing method [PDF]

, 2016
Allan Savory is the man behind holistic grazing and the founder of the Savory Institute. Savory claims that holistic grazing can stop desertification and reduce atmo­spheric carbon dioxide levels to pre-industrial levels in a few decades. In this report,

Spatial variability of soil properties and soil erodibility in the Alqueva reservoir watershed [PDF]

, 2015
The aim of this work is to investigate how the spatial variability of soil properties and soil erodibility (K factor) were affected by the changes in land use allowed by irrigation with water from a reservoir in a semiarid area.

Beyond grassland degradation: Pathways to resilience for pastoralist households in alpine grassland ecosystems

Journal of Environmental Management
Sustaining the development of rural and pastoral communities' hinges on livelihood resilience. Pastoralist household resilience relies on resource availability and decision-making abilities. Despite extensive studies on pastoralist livelihoods, a significant knowledge gap remains in understanding the nuanced adaptive capacities of diverse households ...

Grassland Degradation Decrease the Diversity of Arbuscular Mycorrhizal Fungi Species in Tibet Plateau

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2014
Arbuscular mycorrhizal (AM) fungi play a vital role in restoration of an ecosystem. Grassland degradation in alpine steppe is severe, but the influence of grassland degradation on AM fungi composition in Tibetan Plateau is still not well understood. This

Predicting parameters of degradation succession processes of Tibetan Kobresia grasslands [PDF]

Solid Earth, 2015
Abstract. In the past two decades, increasing human activity (i.e., overgrazing) in the Tibetan Plateau has strongly influenced plant succession processes, resulting in the degradation of alpine grasslands. Therefore, it is necessary to diagnose the degree of degradation to enable implementation of appropriate management for sustainable exploitation ...

EVALUATING REMOTE SENSING TECHNIQUES FOR MONITORING GRASSLAND DEGRADATION

Caminhos de Geografia
Ecosystem degradation is one of the most significant environmental challenges worldwide. In particular, grassland degradation poses serious threat to agricultural productivity, species diversity, and soil stability. This study aimed to compare the applicability of two remote sensing techniques – the Linear Spectral Mixture Model (LSM) and the Grassland
