Contribute To A Definition Of Extensive Grazing (Mediterranean), J. Potes, J. P. F. Almeida, C. Matos, A. Teixeira
IGC Proceedings (1997-2023)
The subject of this paper is a definition of Extensive Grazing from Extensive Systems of Animal Production in Mediterranean environments. The edaphoclimatic characterization is essential to understand the low level of primary productivity as a consequence of irregular precipitation over the year and its absence during the long, dry and hot summer. The powerless of soils justify the limited contribution of plants and make clear the necessary recovery of the soil and storage of water naturally (soil) or artificially (irrigation). Considering the IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) definition of extensive grazing it has been used the …

Permanent grasslands are complex ecosystems which respond with a great variability - in terms of specific richness - to soil type and management strategies. Modelling is a valuable tool to explore these relationships. Our work consisted in adapting the Moorepark St Gilles grass growth model (MoSt GG) designed to model Lolium perenne plant functional type (PFT) pastures (PFT A) to a different PFT (Dactylis glomerata, PFT B) through literature-based parametrization. The model was evaluated under Walloon (Belgium) conditions using growth trials from 2014 to 2018 in two sites with contrasting pedo-climatic conditions. Three to five cuts were performed …
Grasslands, Rangelands, Pastoralists – What Do We Mean?, D. M. Kelly, Ann Waters-Bayer, K. L. Johnson, Maryam Niamir-Fuller, Chris Magero, Tungalag Ulambayer
Grasslands, Rangelands, Pastoralists – What Do We Mean?, D. M. Kelly, Ann Waters-Bayer, K. L. Johnson, Maryam Niamir-Fuller, Chris Magero, Tungalag Ulambayer
IGC Proceedings (1997-2023)
The terms grasslands and rangelands are often confused, but the terms used to describe the people who live and manage these areas are even more confusing. The myriad of words used about these people includes: pastoralists, farmers, ranchers, herders, transhumants, indigenous peoples, nomads, graziers, gauchos. The terms used vary across the world, and meanings vary across time and space. One definition of pastoralists is “livestock-keepers who specialise in taking advantage of variability, managing grazing itineraries at a variety of scales so that livestock feed better than without a herder” (Krätli 2019). The United Nations Decade of Family Farming defines farmers …
Challenges Of Grassland Policies Implementation In Kenya And The Sustainable Development Goals, N. Daari
Challenges Of Grassland Policies Implementation In Kenya And The Sustainable Development Goals, N. Daari
IGC Proceedings (1997-2023)
Since independence, Kenya has found herself at the crossroads caused by economic recession, criminality, corruption and ineptitude leadership that has led to persistent household extreme poverty. It is time now to search for solutions to address the challenges facing sustainable livelihood development in Kenya. This study, therefore examines the challenges of grasslands related policies and their implementation in Kenya and the Sustainable Development Goals (SDGs). A review study of the literature on grasslands and rangelands related policies and laws, SDGs frameworks, government and academic literature was carried out. The study results show that; Kenya has faced challenges of grasslands policies …
Strategic Integration Of Grasslands Within The Agricultural Landscape: Optimizing Benefits For The Producer And Society, A. J. Duff, J. G. Franco

We provide a case study assessment, centered in the Upper Midwest region of the United States, of the economic and environmental outcomes associated with the inclusion of grasslands within dairy production systems. This farmscape design approach can be applied at farm, watershed, and regional scales, and has the potential to significantly improve the resilience of our agricultural lands. Ruminant livestock are uniquely adapted to utilize perennial forages, and the strategic integration of grasslands within the agricultural landscape can improve producer return on investment while generating ecosystem services that benefit the production system and society.

Native perennial warm-season grasses (NWSGs) of the United States (U.S.) provide valuable summer forage. Studies have shown their potential within grazing systems as a complement to cool-season forages, as well as their benefits to soil biota, wildlife biodiversity, carbon sequestration and their resiliency to extreme drought and flood events. In this paper, we demonstrate that, in addition to these benefits, NWSGs provide important economic value to beef and dairy producers as a hedge against financial risks posed by overreliance on cool-season grasses.

Throughout the many decades of grassland and forage research, practitioners have used many different methods to assess botanical composition. While a few of these methods have proven to be accurate and efficient, there has been limited direct comparison between methods. The objective of this study was to determine an accurate and efficient method to determine botanical composition for researchers, practitioners, and students. Six farms with two pastures each were monitored across the state of Kentucky. Sampling started fall 2020 and continued through fall 2022 with measurements taken three times a year using the following measurement techniques: step point, visual estimation, …
New Insights For Benefit Of Legume Inclusion In Grazing Systems, David M. Jaramillo, José C. B. Dubeux Jr., L. M. D. Queiroz, L. Garcia
New Insights For Benefit Of Legume Inclusion In Grazing Systems, David M. Jaramillo, José C. B. Dubeux Jr., L. M. D. Queiroz, L. Garcia
IGC Proceedings (1997-2023)
The benefits and challenges of legume inclusion in grazing systems have been well documented over time and across different regions. Recent investigations have provided novel insights into the benefits of legume inclusion in grazing systems. Our objective is not to provide a wide overview of the benefits of legume inclusion but to explore novel insights of recent advancements made from studies evaluating legume inclusion in grazing systems. Efficiency of resource use through legume inclusion in grazing systems can reduce the water footprint associated with beef production through improvements in forage nutritive value and animal performance. These efficiencies also translate into …
