Decisions on how to move livestock in space and time are central to rangeland management. Despite decades of small-scale research, substantial uncertainty exists regarding the relative importance of cattle stocking rates per se, versus the movement of cattle in both space and time, in achieving desired vegetation and livestock outcomes at scales relevant to livestock producers. We report on a ranch-scale experiment comparing effects of collaborative, adaptive, multi-paddock, rotational management (CARM) versus more traditional, season-long, continuous rangeland management (TRM) on perennial grass density and production, cattle performance, and wildlife habitat, while holding the annual stocking rate the same in …
Challenges Of Pastoralism And Rangelands In Europe, P. Manzano
Challenges Of Pastoralism And Rangelands In Europe, P. Manzano
IGC Proceedings (1997-2023)
High Human Development achievements across Europe explain the situation of pastoralism in the region. While its economic importance has dwindled over the last century in terms of livelihood provision, pastoralism is nonetheless key for supporting rural population - especially in the areas of lower agricultural potential - and for delivering ecosystem services in vast areas. The mainstreaming of scientific research means that pastoralism is increasingly recognized as a sustainable livelihood by the European general public. In spite of this better press, the advanced average age of European pastoralists and the increased gender imbalances pose great sustainability risks in the short- …
Nutrient Return From Plant Litter And Cattle Excretion Grazing On N-Fertilized Grass Or Grass-Legume Pastures In North Florida, Liza Garcia, D. M. Jaramillo, José C. B. Dubeux Jr., Lynn E. Sollenberger, João M. B. Vendramini, N. Dilorenzo, E. R. S. Santos, M. Ruiz-Moreno, L. M. D. Queiroz

Nutrient recycling via plant litter and livestock excreta is an important ecosystem service provided by grasslands. This study determined nutrient return via these pathways in three grazing systems. The experiment was conducted from May to October (2016 and 2017) and treatments were: 1) Nitrogen fertilized bahiagrass (Paspalum notatum Flügge) pastures (112 kg N ha-1) during the warm-season, overseeded with a mixture (56 kg ha-1 of each) of ‘FL 401’ cereal rye (Secale cereale, L.) and ‘RAM’ oat (Avena sativa, L.) during the cool-season (BGN); 2) Ecoturf Rhizoma peanut (Arachis glabrata Benth.)/bahiagrass …
Modelling Grazing And Burning In Communal Rangelands To Help Understand Trade-Offs Between Production, Carbon, And Water, H. J. Hawkins, M. Moradzadeh, M. L. Vermeire, Farai Chikomba, L. Wu
Modelling Grazing And Burning In Communal Rangelands To Help Understand Trade-Offs Between Production, Carbon, And Water, H. J. Hawkins, M. Moradzadeh, M. L. Vermeire, Farai Chikomba, L. Wu

Rangelands cover more than 80% of South Africa’s land area, providing critical ecosystem services, livelihoods and cultural values related to livestock. Communally owned rangelands are often overgrazed and subject to runaway fires but lack of data limits our understanding of how these threats impact production. In this transdisciplinary project, we use models to test hypotheses and predict future scenarios as a planning tool for resource-poor communal farmers. We think that moderate grazing and fire regimes will increase overall production and carbon sequestration with uncertain trade-offs for water and nutrient cycling. To test this, we trained two process-based biogeochemical models (DAYCENT …
Tree Legumes As Sustainable Ecosystem Services In Livestock Systems, James P. Muir, C. E. Cooper, V. Corriher-Olson
Tree Legumes As Sustainable Ecosystem Services In Livestock Systems, James P. Muir, C. E. Cooper, V. Corriher-Olson
IGC Proceedings (1997-2023)
Arboreal legumes provide multiple uses in pastures and rangelands. Trees directly and indirectly feed, house, doctor, and warm humans at minimal environmental cost through forage (fodder), timber, biofuel, medicines, as well as edible leaves, pods, and seeds. Leguminous trees, because they foster biological nitrogen fixation (BNF) and acquire deep-soil nutrients and moisture, compete less with herbaceous plants for shallow-horizon soil moisture and nutrients. Their ecosystem services (ES) are generally less obvious and quantifiable. These include converting CO2 to sequestered C and released O2 in N-poor soils where trees without BNF do not thrive. Other ES include shade for …

The Pantanal wetland is a mosaic of landscapes that brings together rich biodiversity with the valuable activities of fishing, tourism and ranching. Human occupation and land use in the headwaters have intensified the rate of channel avulsions in the lower reaches of the largest megafan on the Taquari River. This study evaluates the long-term changes of landscapes in the active depositional lobe of the Taquari megafan from the perspective of local communities of pantaneiros. Maps derived from multiple decades of multispectral Landsat data have proven useful for studying land cover changes through the relationship between dry (terrestrial vegetation and …

Ecosystem services are benefits that the natural environment provides to support human well-being. A thorough understanding and assessment of these services are critical to maintain ecosystem services flow through sustainable land management to optimize bundles of ecosystem services provision. Maximizing one particular ecosystem service may lead to reduction in another. Therefore, identifying ecosystem services tradeoffs and synergies is key in addressing this challenge. However, the identification of multiple ecosystem services tradeoffs and synergies is still limited. A previous study failed to effectively capture the spatial interaction among ecosystem services as it was limited by “space-to-time” substitution method used because of …
