Maris: Scalable Online Scenario Development Tool For Rangeland Conservancy Managers Using High Spatial-Temporal Resolution Carrying Capacity Maps And Livestock Market Data, L. G. J. Boerboom, R. O. Ohuru, A. G. Toxopeus, W. Nieuwenhuis, C. A. J. M. De Bie, P. K. Mwangi, M. L. Schouwenburg, R. L. G. Lemmens

IGC Proceedings (1977-2023)

Although the management of livestock numbers within the bounds of carrying capacity of African rangelands is a way to manage risks, both scientists and practitioners, caution against a momentary and local use of carrying capacity as a management indicator. Carrying capacity should be seen in wider spatial and temporal/seasonal context as well as in a social and economic context. Given the large numbers of conservancies across Kenya, and its Maasai Mara region in particular, with many more landowner members, it is difficult for conservancies’ managers to contextualize phenomena such as carrying capacity and market price over space and time.

Silvopastoral Strategy And Sustainable Management Of Forests In Morocco, Mustapha Naggar, Said Lahssini, Said Moukrim, Anass Legdou

IGC Proceedings (1977-2023)

In Morocco, forests act as a grazing reserve all year long and in a normal year produce 1.5 billion feed units, i.e. 17 % of the national forage assessment. The pastoral question is one of the factors involved in the desertification of forested areas against a bioclimatic background where more than 93% of the national territory is arid. In 2016, the Water and Forestry Department in cooperation with its partners, devised a nation-wide sylvo-pastoral strategy. The approach adopted consists in sustainably managing sylvo-pastoral resources over the long term based on good governance of all goods and services offered by forested …

Effects Of Agroforestry Practices On Soil Properties In The Drylands Of Eastern Kenya, Nicholas Syano Mutuku, Moses M. Nyangito, Geoffrey Kironchi, Oliver Vivian Wasonga

IGC Proceedings (1977-2023)

Drylands, which are home to about 2 billion people face a myriad of problems among them low land productivity. Agroforestry is one of the land use practices that is perceived to be sustainable with beneficial effects on soil properties. However, the effects of agroforestry practices on soils especially in the drylands have rarely been quantified and studied in details. The study determined the effects of selected agroforestry practices on soil properties in Makueni County of Kenya where agroforestry has been promoted by various organizations. Four soil samples were collected at 0-15cm, 15-30cm, 30-45cm and 45-60cm depths in a zigzag pattern …

Adaptive, Multi-Paddock, Rotational Grazing Management: An Experimental, Ranch-Scale Assessment Of Effects On Multiple Ecosystem Services, D. J. Augustine, J. D. Derner, L. M. Porensky, H. Wilmer, María E. Fernández-Giménez, David D. Briske

IGC Proceedings (1977-2023)

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 …

Status, Management, And Governance Of The Communal Grasslands Of Ethiopia’S Highlands: A Disappearing Asset For Mixed Crop-Livestock Livelihood Systems, Bedasa Eba, Fiona Flintan, Tesfa Getachew, Jason Sircely

IGC Proceedings (1977-2023)

There is little documentation about the status, management, and governance of the communal grasslands of Ethiopia’s highlands. However, research being carried out by ILRI (International Livestock Research Institute) in northern Shewa, Amhara region, is highlighting their importance as a critical resource for those farmers engaged in mixed crop-livestock livelihood systems across the highland areas. These grassland areas range from 2 to 200 hectares and can be used by up to four different villages or ‘kebele’ and providing on average 10-20% of livestock feed for local farmers. However, this important resource is rapidly disappearing with encroachment of farming and tree-planting with …

Made To Graze: Using Cattle To Regenerate Soil Health, Debby Dulworth

Kentucky Grazing Conference

Beyond being a cattle farm in extreme western Kentucky, Dogwood Farm is part of an ecosystem dominated by the nearby Ohio and Mississippi Rivers. Northern Ballard County was still a wilderness of temperate rainforest in 1840, when settlers began clearing trees to convert it to farm land. Almost every year since, more land has been cleared, tilled and planted to crops.

Dogwood Farm pastures offer examples of several different ways to affordably and profitably convert long‐farmed row‐crop land‐‐most of which had previously grown annual monocultures of corn, winter wheat and soybeans for many decades‐‐back to perennials that will keep the …

Flexible Fencing And Watering Systems For Rotational Grazing, Morgan Hayes

Kentucky Grazing Conference

Creating proper and watering systems is critical for managing livestock. Not only do farmers need fencing to contain their livestock on their property, but also to ensure the livestock eat down the forage intended rather than areas that are supposed to be rested. With temporary fencing there are many options for laying out flexible fencing which will be discussed below. In many rotational grazing setups access to water is the limiting factor. There are options and considerations that can make a watering system more flexible as well. When trying to develop or improve a rotational grazing strategy being able to …

Precision Ag Isn’T Just For The Row Crop Guys, Christopher D. Teutsch

Kentucky Grazing Conference

Guidance utilizing the global positioning system (GPS) has long been used for various operations in row crop agriculture. However, the high price of these systems has limited use in low input forage‐livestock operations. Reduced prices and the availability of used guidance systems has the potential to increase the use of precision agriculture in ruminant operations. Currently, entry level guidance systems can be purchased for $1,000 to 2,500.

Participatory Observatories To Connect Multifunctional Landscapes, Link Smallholder Farmers, And Collectively Diversify Income, I. Espejel Carvajal, G. Romero, O. Pérez, R. Yaguez, Elisabeth Huber-Sannwald, N. Martínez Tagueña, C. L. Lauterio Martínez, V. M. Reyes Gómez, S. Lucatello

IGC Proceedings (1977-2023)

Cattle ranching was introduced to Baja California, Mexico (semiarid and arid climates) by the Spaniards, who brought the animals and the techniques. One important activity was moving livestock from the mountains (forests and few kinds of grass) to the coast crossing poor shrublands known as chaparrals. Fire was a common practice to promote grass growth and pastoralists could move through the land freely. Pastoralism became a common practice when English workers built the Ensenada port and became ranching landowners. They followed the practice of livestock movement through the exorreic watersheds. Native Indians, as well as other Mexicans known as ejidatarios, …

Participatory Management Of Rangeland Hydrology – A New Socio-Ecological Technology To Effectively Adapt To And Mitigate Climate Change: Case From Morocco, Lhoussaine Bouchaou, El Hassane El Mahdad, El Hassan Beraaouz, Abdelfettah Sifeddine, Alessandro Rizzo, Mohamed Hssaisoune, Hanane Reddad, Abdelghani Chehbouni, Elisabeth Huber-Sannwald

IGC Proceedings (1977-2023)

Morocco’s drylands cover over 90% of the land area; low and irregular rainfall and high potential evaporation contribute to extremely high-water deficits. These phenomena have greatly impacted rangeland hydrology and nomadic and transhumant pastoralism. To adapt to this predominant water deficit, the inhabitants of these areas have developed two forms of lifestyles, which include household and livestock mobility: (i) a pendulum movement for seasonal transhumance between the mountains and their bordering plains; and (ii) random nomadic mobility regulated by the sporadic frequency of rains and thus water availability. In both cases, this mobility is controlled by the degree of development …

Bale Grazing: Feeding Hay The Rotational Grazing Way, Gregory S. Halich

Kentucky Grazing Conference

Imagine a hay feeding system where you did not have to use a tractor for months at a time and that allowed you to build up pasture fertility without applying commercial fertilizer. Would this be of interest to you? What if this same system also kept your cattle clean during the winter without coats caked in mud and manure, allowed you to creep graze fall‐born calves, and built up the organic matter levels in your pasture soils. Would you be even more interested? As far‐fetched as this may sound, all these benefits are possible with an innovative winter‐feeding technique called …

Right Rate, Timing, Source And Placement: More Bang For The Pasture Fertilizer Buck, John H. Grove, Christopher D. Teutsch

Kentucky Grazing Conference

As we write this paper for the conference, fall fertilizer prices continue to increase, albeit at a slower pace than earlier this fall for most materials. The latest DTN retail price survey https://www.dtnpf.com/agriculture/web/ag/crops/article/2021/10/06/fertilizer‐price‐gains-losing‐steam has urea (46‐0‐0) at $620/ton, DAP (18‐46‐0) at $722/ton and potash (0‐ 0‐60) at $647/ton. This gives $0.675/lb N, $0.52/lb P₂O₅ (after the N value in DAP price was accounted for), and $0.54/lb K₂O. Compared to this time last year, urea, DAP and muriate of potash are 71, 64 and 92% higher, respectively. Other important materials used in Kentucky are also higher: …

An Integrated Approach To Weed Management In Pastures, Jonathan D. Green

Kentucky Grazing Conference

Weeds reduce the quantity and the stand life of desirable forage plants in pastures and diminish the palatability and quality of the forages available for livestock grazing. In some situations, certain weed species are potentially poisonous to grazing animals. The aesthetic value of a pasture is also impacted by weeds. Therefore, it is often desirable to implement weed management strategies that reduce the impact of weeds on pasture productivity.

Introduction To Pasture Ecology, Ed Rayburn

Kentucky Grazing Conference

Pasture‐based livestock production is an integrated process. Plants intercept solar energy, take up soil water and minerals, making carbohydrates and proteins to feed themselves. Animals graze the pasture. Microbes in the animal’s rumen digest the forage and are then digested by the animal to provide energy, protein, and minerals for animal maintenance, growth, and milk production. Dead plant tops and roots along with manure and urine provide energy and protein to soil organisms. The soil organisms maintain soil pore space and structure, provide water infiltration and soil water holding capacity, and cycle nutrients into forms that can be taken up …

Mongolian Herders’ Evaluation Of Rangeland Ecosystems Services, Values, And Changes Over The Past Decade, T. Ulambayar, B. Yunden, N. Davaasuren, S. Balt, D. Davaajav, B. Zambuu

IGC Proceedings (1977-2023)

Mongolia's rangeland is one of the largest remaining contiguous ecosystems encompassing 2.6% of the global grasslands, and almost three-fourths of the country's territory provides essential ecosystem services (ESS) for over 3 million Mongolians and 71 million livestock. The well-being of 171,605 pastoral households directly depends on the rangelands receiving provisional services in the forms of nutrition, material use and energy, regulatory services, and cultural services. This study explored herders' perceptions of these ESS, their evaluation for ESS values, and observations of ESS change for the last decade. The study found that Mongolian herders have more benefits from provisional ESS (on …

Conceptualizing Pastoral Development Based On Carbon Sequestration: The Case Of Yabelo District In The Southern Ethiopian Rangelands, D. L. Coppock

IGC Proceedings (1977-2023)

Major challenges for rangeland stewardship in the developing world include how to mitigate the spread of pastoral poverty and environmental degradation. Arresting such trends requires a scale of investment, policy incentives, and institutional commitments not previously observed in pastoral development. Indeed, such a rangeland revolution requires several global events to set the stage, namely: (1) Creation of markets for diverse ecosystem services; (2) recognition that improved rangeland stewardship is vital to mitigate climate change; and (3) distribution of green climate funds in support of local projects. New approaches for pastoral development projects are also needed. Previous projects have largely focused …

Wildlife Conservation And The Role Of The Indigenous Communities Living Around Conservation Areas, N. Parmisa, K. A. Galvin

IGC Proceedings (1977-2023)

The Indigenous Kenyan Maasai community has coexisted with the wildlife surrounding it for decades from Nairobi National Park, Maasai Mara and Amboseli. These parks border Maasai lands. Although the northern, eastern, and western perimeters of the Nairobi National Park are fenced, the southern part is not. It is at this point that the Maasai community’s land meets the park. This area also acts as a wildlife dispersal area where wildlife can freely migrate to other parks, including Maasai Mara and Amboseli. The park is only 117sq kms and its vitality depends on the plains to the south where the Maasai …

The Impacts Of The Eco-Environmental Policy On Grassland Degradation And Livestock Production: An Empirical Analysis Based On The Simultaneous Equation Model, M. Liu, J. J. Tang, S. Min, J. K. Huang

IGC Proceedings (1977-2023)

Grassland degradation has been deteriorating while the demands for meat products have been surging in China over the past few decades, leading to multiple policy initiatives to balance the grassland ecosystem and livestock production of the pastoral areas. This paper investigates the impacts of a prevailing eco-environmental program, i.e. Subsidy and Incentive System for Grassland Conservation (SISGC), in the pastoral areas of Inner Mongolia, on grassland condition and livestock production. The Normalized Difference Vegetation Index (NDVI), measured with remote sensing technology, is used to quantify grassland condition. Our empirical analysis was based on the data of 52 counties across a …

The Role Of Women In Rural Livestock: Which Women? Which Livestock?, Gabriela Litre, Daniela Nogueira, Alessandra Matte, Virginia Courdin

IGC Proceedings (1977-2023)

We explore the conceptual and empirical limitations of the question about “the role of women in rural livestock production” as well as the widespread assumption that women in livestock are subsistence or smallholder farmers. While this is correct in many situations, “essentialist” development discourses often disregard new demographic trends and the heterogeneity of live-stock production systems. Our research, which focuses on the livelihoods of women involved with livestock production in the Pampas’ grasslands of Brazil, proposes: 1) to critically analyse some of the most widely spread assumptions about women involved in beef livestock production, including the belief that women are …

Shift In Management Strategy Of Yak Herding In The South Of Mustang District, Nepal, Himalaya, H. Anzai, M. K. Shah, Hajime Kumagai

IGC Proceedings (1977-2023)

In the Himalayan regions of Nepal, people herd yaks (Bos grunniens) under transhumant pastoralism, seasonal migrations of herds between summer highlands and winter lowlands. For several decades, the number of yaks has decreased, and the management strategy of yak herding has been altered due to the influence of substantial changes in both the social environment and their livelihoods. We conducted field surveys on yak herding in the south of Mustang District from 2012 to 2016 to examine the recent shift in management strategy and practice. The surveys were focused on fifteen yak owners and their herdsmen who lived …

Valuing The Expertise Of Mobile Herders In Arid South Africa--A Photographic Essay, C. F. Cupido, W. Ellis, M. I. Samuels

IGC Proceedings (1977-2023)

Pastoralism has been practiced for millennia in numerous ecosystems across the world. Throughout history, pastoral systems and in particular herding have been replaced by the commercialization of livestock production, which essentially made herders redundant in many sub-Sahara countries resulting in job losses. Herding is however still practiced in many countries, but the essential role of the herder is in many instances snubbed upon and disregarded as trivial work, hence their low social standing within the community. Literature however indicates that herding does offer many benefits over commercial paddock systems e.g. improving rural livelihoods, reviving customary practice, reducing stock theft, reducing …

Exploring Institutional Complementarity And Social Thresholds Of Mobility In Pastoral Social-Ecological Systems In Mongolia, Ulan Kasymov, Irene Ring

IGC Proceedings (1977-2023)

Biodiversity continues to decline worldwide, affecting dryland ecosystems that are of significant importance for global biodiversity conservation. Accelerated by climate change, undergoing transformations have been pushing the entire social-ecological system across ecological and social thresholds. Particularly, the decline of pastoral mobility in Mongolia is of great concern, as flexible responses to the dynamic environment are crucial for the sustainability of drylands’ ecosystems. Responding to this concern, Mongolian policymakers design new pasture use and conservation policies. However, the policies might be ineffective in preventing systems from crossing the thresholds, unless policy implementation succeeds in systematically shaping the perceptions of a critical …

Transdisciplinary Research In Practice: Lessons From Participatory, Folklore And Community-Supported Approaches In The Greater American West, H. Wilmer, L. Carr Childers, L. M. Porensky

IGC Proceedings (1977-2023)

Rapid social and ecological changes on global rangelands amplify the challenges to achieving biodiversity conservation, rural economic viability and social well-being, and rangeland sustainability. These dynamics create a need for transdisciplinary science that is inclusive of ecological, sociological, and participatory approaches in order to rebuild meaningful working relationships between scientists, ranchers and managers, and other rangeland stakeholders. In real application, however, transdisciplinary science faces numerous social, ethical, and logistical challenges, including the question of how the work might benefit rangeland stakeholders. Our objective is to advance rangeland researchers’ toolbox for meaningful engaged research by describing three lessons from transdisciplinary projects …

Action Plan For The International Year Of Rangelands And Pastoralists (Iyrp): The Case For The United States, Canada, And Mexico, Barry Irving, Larry Howery, Jürgen Hoth, Jess Peterson

IGC Proceedings (1977-2023)

The GAP analysis (A Case of Benign Neglect: Knowledge gaps about sustainability in rangelands and pastoralism) points to several gaps that are relevant to the US, Canada and Mexico. North American rangelands span the ecological continuum of polar to hot deserts and arid to humid climates that exhibit highly variable ecological and forage production potential across time and space. Although there is a great deal of rangeland research, extension, and inventory capacity in all three countries, a weak link is the dissemination of information to North American pastoralists (conventionally referred to as ranchers or producers). Although the extension system in …
