Historical Land Use Dynamics in the Highly Degraded Landscape of the Calhoun Critical Zone Observatory

Peer-reviewed publication
июня, 2017

Processes of land degradation and regeneration display fine scale heterogeneity often intimately linked with land use. Yet, examinations of the relationships between land use and land degradation often lack the resolution necessary to understand how local institutions differentially modulate feedback between individual farmers and the spatially heterogeneous effects of land use on soils. In this paper, we examine an historical example of a transition from agriculture to forest dominated land use (c. 1933–1941) in a highly degraded landscape on the Piedmont of South Carolina.

World Day to Combat Desertification - 2017

India

Since 1995, June 17th has been observed as the "World Day to Combat Desertification - 2017"  The main objective of commemorating WDCD has been to promote public awareness about international efforts to combat desertification and the effects of drought collectively.

This report provides commemoration of WDCD 2017 across india on awraness, workshops, nature camps, schemes and events launched.

This report highlights the activities pertaining to issues related to desertification, land degradation and drought, 

A comparative assessment of land management approaches in Bhutan

Peer-reviewed publication
июня, 2017
Bhutan

Arable land in Bhutan is under serious threats of land degradation. Proper land management approach is needed to control soil erosion problems. This study is an attempt to characterize and document the conventional and the community-based land management approaches, applied in Chukha and Dagana districts, respectively. The study tried to make a comparative assessment of their social, economic and environmental impacts on the participating farmers.

Restoring Degraded Rangelands in Jordan: Optimizing Mechanized Micro Water Harvesting using Rangeland Hydrology and Erosion Model (RHEM)

Jordan’s rangelands, the so called Badia, home of the Bedouins, are threatened through a combination of
over-exploitation of the ecosystem services and a changing climate towards drier seasons and highly
erratic rainfalls. In the recent decades, the once productive grazing lands transformed into sparsely
vegetated and crusted desert grounds not capable of retaining the sporadic rainwater within the landscape
- and consequentialsurface runoff inevitably acceleratessoil erosion and gullying. To counter-measure the

Managing rangelands: promoting sustainable practices: Reseeding: a practical and costeffective technique that enhances ecological sustainability while strengthening system resilience

Policy Papers & Briefs

Global

The problem of rangeland degradation can be reversed through revegetation, for example through inclusion of various locally adapted native species in the reseeding. Reseeding is the process by which rangelands are rehabilitated and it has two purposes; to ‘repair’ the degenerated rangeland system, and to increase the forage available for grazing animals. It involves sowing seeds directly into their final growing position, and is applied on rangelands with an advanced degree of degradation, low plant density or poor productivity levels.

Global Geo-informatics Options by Context (GeOC) Tool for Supporting Better Targeting and Scaling-out of Sustainable Land Management: Designing the System and Use Cases

Sustainable Land Management (SLM) are required to achieve Land Degradation Neutrality (LDN). SLM options are fitted to the social, economic and ecological contexts. The high contextual diversity of drylands in particular prevents the design and application of “uniform blanket” policies to promote SLM over large scales where significant impact is expected.
