Abstract The United Nations Convention to Combat Desertification and its sister conventions, the Framework on Climate Change Biological Diversity, all aim halt or mitigate deterioration of ecological processes which life depends. Sustainable land management (SLM) is fundamental achieving goals three Conventions. Changes in undertaken address dryland degradation desertification can simultaneously reduce net greenhouse gas emissions contribute conservation biodiversity. Management protect...

Abstract Although sustainable land management (SLM) is widely promoted to prevent and mitigate degradation desertification, its monitoring assessment (M&A) has received much less attention. This paper compiles methodological approaches which date have been little reported in the literature. It draws lessons from these experiences identifies common elements future pathways as a basis for global approach. The starts with local level methods where World Overview of Conservation Approaches...

Savannah ecosystems face significant threats from land degradation, including woody vegetation encroachment. This study introduces a high-resolution method for mapping the fraction of savannah cover by integrating optical (Sentinel-2, S2), radar (Sentinel-1, S1), and auxiliary data. First, comprehensive training dataset fractional (FWC) samples was developed very imagery thousands manually annotated points. Shallow deep learning algorithms were utilised to generate classification masks, with...

Land management evaluation can be made more relevant and holistic by incorporating local knowledge perspectives. We examined whether photo elicitation photovoice could enhance semi-structured interviews in capturing livestock farmers' perspectives a participatory Mier Molopo, South Africa. The participants discussed themes including veld condition, land management, criteria. Photo provided details (62% of instances analyzed [Mier]; 58% [Molopo]) new information (75% 65% beyond those...

The United Nations Convention to Combat Desertification (UNCCD) has lacked an efficient mechanism access scientific knowledge since entering into force in 1996. In 2011 it decided convene Ad Hoc Working Group on Scientific Advice (AGSA) and gave a unique challenge: design new for science-policy communication based the best available evidence. This paper outlines innovative 'modular mechanism' which AGSA proposed UNCCD September 2013, how was designed. Framed by boundary organization model,...

Abstract In semi‐arid regions, the effects of grazing or sparing management on natural communities long‐lived plants generally take decades to become evident. Event‐driven dynamic behaviour, unpredictable and low rainfall, complicated interactions between species make it difficult gather sufficient understanding vegetation dynamics be able develop guidelines for sustainable management. Simulation models that consider essential processes determine offer scope quantitatively exploring...

Background: One of the main causes land degradation in South Africa is bush thickening (BT) mainly Senegalia or Vachellia species. Restoration methods are required to control BT, and improve grass biomass production soil conditions Africa.Objectives: The objectives this study were determine effect brush packing (BP) as a restoration method increase production, assess moisture after BP on different types, document perceptions local communities towards BP.Method: Methods included cutting stems...

The Grassland biome is the most transformed in South Africa, with cultivation and other human impacts having largest effect on pristine grasslands. Conversion of natural grassland to cropland agriculture destroys vegetation seed banks. When croplands African Highveld are abandoned, secondary succession often leads low diversity Hyparrhenia hirta dominated plant communities. To investigate reseeding botanical diversity, various treatments restoration were established a recently abandoned at...
