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

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.

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.

In vitro fermentation profile and methane production of Kikuyu grass harvested at different sward heights

Diciembre, 2020
Global

Highly digestible forages are associated with an in vitro low-methane (CH4) rumen fermentation profile and thus the possibility of reducing CH4 emissions from forage-based systems. We aimed to assess the in vitro ruminal fermentation profile, including CH4 production, of the top stratum of Kikuyu grass (Cenchrus clandestinus - Hochst. ex Chiov) harvested at different sward heights (10, 15, 20, 25, and 30 cm). Herbage samples (incubating substrate) were analyzed for their chemical composition, in vitro organic matter digestibility (IVOMD), and morphological components.

Indirect Effects of Grazing on Wind-Dispersed Elm Seeds in Sparse Woodlands of Northern China

Peer-reviewed publication
Diciembre, 2020
Global

Grazing leads to the reduction of biomass and plays a critical role in land degradation in arid and semiarid lands. However, the indirect effects of grazing on the ecosystem, e.g., the effect on seed dispersal, have not been well understood. In this study, we built an agent-based model (ABM) to simulate how grazing intensity affects the seed dispersal of elm trees, one of the native vegetation species of temperate woodlands in semiarid lands. The simulated results from the ABM and observed data from the real world were compared to assess the accuracy and validity of the ABM.

Changes in Livestock Grazing Efficiency Incorporating Grassland Productivity: The Case of Hulun Buir, China

Recently, improving technical efficiency is an effective way to enhance the quality of grass-based livestock husbandry production and promote an increase in the income of herdsmen, especially in the background of a continuing intensification of climate change processes.

The Effect of Grazing on the Temperature Regime of the Alas Soils of Central Yakutia

Peer-reviewed publication
Septiembre, 2020
Global

There are numerous studies on the effect of grazing on the physical and chemical parameters of soils. However, the impact of grazing on the temperature regime of the alas soils in Central Yakutia is still poorly understood. This paper presents the results of long-term observations of the state of the soil-and-plant cover of thermokarst basins—i.e., alases—located in the Lena-Amga interfluve and actively used as pastureland.

Carbon Storage Potential of Silvopastoral Systems of Colombia

Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands.

Pastoralists and peasants: perspectives on agrarian change

Agosto, 2020

Land in Cameroon is under growing pressure – powerful commercial interests;changing climate conditions and shifting demographic flows including mass migration and increasing population density. The rights of rural communities and indigenous people to access and use land for farming and grazing have been eroded,  primarily due to failure to recognise customary land tenure rights;land use conflicts and lack of effective local governance. The country’s land legislation is outdated and not compatible with customary law and local realities.

Sustainable Land Management, Wildfire Risk and the Role of Grazing in Mediterranean Urban-Rural Interfaces: A Regional Approach from Greece

Peer-reviewed publication

Europe

Mediterranean regions are likely to be the most vulnerable areas to wildfires in Europe. In this context, land-use change has promoted land abandonment and the consequent accumulation of biomass (fuel) in (progressively less managed) forests and (non-forest) natural land, causing higher fire density and severity, economic damage, and land degradation. The expansion of Wildland-Urban Interfaces (WUIs) further affects fire density by negatively impacting peri-urban farming and livestock density.

Do Certificates of Customary Ownership as currently issued and delivered translate into more secure land rights for women and men involved: a case study of Nwoya using data collected by the Ministry of Lands;Housing and Urban Development

The Gambos municipality is part of Angolamilk region. However milk;which is life sustaining in these communities;was found to be in short supply due to diminishing grazing pastures correlating with the introduction of commercial cattle ranches to the area. It is the impact of commercial ranches on pastoralists which has removed their buffer against droughts and thus dangerously threatened food security.

An Assessment of Multiple Drivers Determining Woody Species Composition and Structure: A Case Study from the Kalahari, Botswana

Peer-reviewed publication

Savannas are extremely important socio-economic landscapes, with pastoralist societies relying on these ecosystems to sustain their livelihoods and economy. Globally, there is an increase of woody vegetation in these ecosystems, degrading the potential of these multi-functional landscapes to sustain societies and wildlife. Several mechanisms have been invoked to explain the processes responsible for woody vegetation composition; however, these are often investigated separately at scales not best suited to land-managers, thereby impeding the evaluation of their relative importance.
