Application of Drone and WorldView-4 Satellite Data in Mapping and Monitoring Grazing Land Cover and Pasture Quality: Pre- and Post-Flooding

Peer-reviewed publication
Marzo, 2021
Global

Frequent flooding worldwide, especially in grazing environments, requires mapping and monitoring grazing land cover and pasture quality to support land management. Although drones, satellite, and machine learning technologies can be used to map land cover and pasture quality, there have been limited applications in grazing land environments, especially monitoring land cover change and pasture quality pre- and post-flood events. The use of high spatial resolution drone and satellite data such as WorldView-4 can provide effective mapping and monitoring in grazing land environments.

Botanical Composition and Species Diversity of Arid and Desert Rangelands in Tataouine, Tunisia

Peer-reviewed publication
Marzo, 2021
Tunisia

Natural rangelands occupy about 5.5 million hectares of Tunisia’s landmass, and 38% of this area is in Tataouine governorate. Although efforts towards natural restoration are increasing rapidly as a result of restoration projects, the area of degraded rangelands has continued to expand and the severity of desertification has continued to intensify. Any damage caused by disturbances, such as grazing and recurrent drought, may be masked by a return of favorable rainfall conditions.

Governing drylands as global environmental commons

Journal Articles & Books
Febrero, 2021
Global

Meeting the Sustainable Development Goals requires drylands sustainability. Treating drylands as global environmental commons enables better tailored governance responses. Key nested governance elements for drylands involve setting goals, monitoring and delivering sanctions across scales. The present global governance system for drylands only partially delivers these elements. Drylands require a particular focus on linking local and global governance.

Expériences du quota et de l'accès collectif dans le delta de la vallée du fleuve Sénégal

Reports & Research

Sénégal

Le phénomène d’ATGE gagne l’ensemble du Sénégal, privant les communautés de leurs droits fonciers, des principaux moyens d’existance. L’IPAR, en partenariat avec le CNCR et aGter, a bénéficié d’un appui financier du CRDI pour exécuter ce projet de recherche- action participative et collaborative.

Ce projet évalue des initiatives mises en œuvre et analyse du contexte global de trois communes, situées dans trois zones agro-écologiques : bassin arachidier, Niayes et vallée du fleuve Sénégal, afin de :

 

Mediterranean Landscape Re-Greening at the Expense of South American Agricultural Expansion

The stabling of livestock farming implies changes in both local ecosystems (regeneration of forest stands via reduced grazing) and those located thousands of kilometers away (deforestation to produce grain for feeding livestock). Despite their importance, these externalities are poorly known. Here we evaluated how the intensification and confinement of livestock in Spain has affected forest surface changes there and in South America, the largest provider of soybeans for animal feed to the European Union.

The Production of Pastoral Space: Modeling Spatial Occupation of Grazing Land for Environmental Impact Assessment Using Structural Equation Modeling

Peer-reviewed publication
Febrero, 2021
Mongolia

Environmental impact assessment (EIA) is a key tool for both environmental and land management. It identifies potential adverse and unintended consequences of the projects on land use and the environment and derives possible mitigation measures to address these impacts. Calculating the volume and severity of impacts is complex and often relies on selections and simplifications. Moreover, calculating impacts associated with nomadic-pastoral (dynamic) land use is still an unresolved methodological problem.

Changes in Vegetation of Flooded Savannas Subject to Cattle Grazing and Fire in Plains of Colombia

Peer-reviewed publication

United States of America

Cattle grazing and fire are common types of management on natural ecosystems, generating several threats to the conservation of native vegetation (e.g., changes in species richness, cover, and abundance, mainly of bovine-palatable species). In this work, we analysed the response of the structure and composition of vegetation managed with different cattle stocking rates and fire in the savanna ecosystems of Colombia. The study was located in the eastern area of the Llanos region, where savannas were subjected to grazing and burning.

Emerging from Below? Understanding the Livelihood Trajectories of Smallholder Livestock Farmers in Eastern Cape Province, South Africa

In the context of current agrarian reform efforts in South Africa, this paper analyses the livelihood trajectories of ‘emergent’ farmers in Eastern Cape Province. We apply a rural livelihoods framework to 60 emergent cattle farmers to understand the different capitals they have drawn upon in transitioning to their current class positions and associated vulnerability. The analysis shows that, for the majority of farmers, no real ‘transition’ from subsistence farming has occurred.

Increased climate variability and sedentarization in Tanzania: Health and nutrition implications on pastoral communities of Mvomero and Handeni districts, Tanzania

Journal Articles & Books

Tanzania

African pastoralists are undergoing significant changes in livelihood strategies, from predominantly mobile pastoralism to agro-pastoralism in which both livestock raising and cultivation of crops are practiced, to agro-pastoralism combined with wage labor and petty trade. These changes often result in fixed settlements or a process known as sedentarization.

Are livestock always bad for the planet?

Reports & Research
Enero, 2021
Global

Urgent climate challenges have triggered calls for radical, widespread changes in what we eat, pushing for the drastic reduction if not elimination of animal-source foods from our diets. But high-profile debates, based on patchy evidence, are failing to differentiate between varied landscapes, environments and production methods. Relatively lowimpact, extensive livestock production, such as pastoralism, is being lumped in with industrial systems in the conversation about the future of food.

Assessing Interactions between Agriculture, Livestock Grazing and Wildlife Conservation Land Uses: A Historical Example from East Africa

Eastern Africa

Despite mobile livestock grazing being widely recognized as one of the most viable and sustainable land uses for semi-arid savanna, which can deliver clear wildlife conservation benefits, the levels of pastoral sedentarization and transitions to agricultural livelihoods continue to rise in many pastoral communities across the world. Using questionnaire interviews with community elders, our study assessed changing trends in livestock grazing, wildlife conservation, and sedentarization levels from the 1960s to the present day across three savannas in southern Kenya.
