The Cleaned Approach For Flagging And Addressing Environmental Issues, A. Notenbaert, B. Paul, R. Van Der Hoek, J. Mukiri

IGC Proceedings (1977-2023)

While livestock presents an important livelihood strategy for many smallholders, it is also held responsible for important environmental impacts. In this paper, we used an online survey to identify the perceptions of global livestock experts on environmental impacts of livestock and how these might be tackled. We then explored how the CLEANED environmental ex-ante assessment tool (Comprehensive Livestock Environmental Assessment for improved Nutrition, a secured Environment and sustainable Development = CLEANED) responds to this and how it can be used to influence decision making towards more environmentally-friendly livestock production.

According to the survey, there was general agreement between researchers, development …

Free ranging cattle were randomly selected from participating households and were fitted with neck GPS collars, which recorded geographic position every five-minute interval during wet and dry season. The study identified three production domains where cattle were reported to be spending most of their time grazing, separated by bound polygons on google earth Pro to further extract MODIS EVI???. The recorded GPS points were loaded into google earth Pro to analyse the distribution of cattle grazing in …

Bioeconomic Model For Decision-Making On Fattening Beef-Cattle, G. Ferreira, O. Cardozo, J. M. Soares De Lima

IGC Proceedings (1977-2023)

Profitability and competitiveness of agricultural systems it is closely related with the technology used. Economic and financial appraisal of investments on pasture improvements, facilities, feed and management plans, etc. are often required in order to make decisions. A bio-economic simulation model was developed in order to support decision making on beef-cattle grazing fattening. The aim of the model is to show the relationship between the technological alternative analysed in physical terms as well as financial and economic. By this way it is possible to asset and relate the bio-economic impact of the different animal and pasture management alternative technologies. Results …

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 …

IGC Proceedings (1977-2023)

Climate change threatens the ability of global rangelands to provide food, support livelihoods and deliver important ecosystems services. The extent and magnitude of potential impacts are however poorly understood. In this study, we review the risk of climate impacts along the rangeland systems food supply chain. We also present results from biophysical modelling simulations and spatial data analyses to identify where and to what extent rangelands may be at climatic risk. Although a quantification of the net impacts of climate change on rangeland production systems is beyond the reach of our current understanding, there is strong evidence that there will …

Food Security In Crop, Livestock And Mixed Farming Systems In Mali, C. Reiber, A. Carbajal, S. Traoré, R. Birner, M. Chagunda

IGC Proceedings (1977-2023)

This study evaluates the food security status, its determinants and the coping strategies in crop, livestock and mixed crop-livestock systems in southern Mali. Interviews were conducted with 258 households that were categorized into the three farming systems based on the revenue from livestock and crop production. A linear mixed model was used to analyse the effects of household characteristics on food security using the food consumption score (FCS), household dietary diversity score (HDDS), a modified household food insecurity access scale (mHFIAS) and coping strategies as indicators. Food consumption score was significantly influenced by the farming system with highest FCS for …

IGC Proceedings (1977-2023)

The development of markets and agricultural productivity need participative research approaches that involve farmers, stakeholders and actors in the value chains of agricultural products and inputs. This study illustrates the use of multi-stakeholder platforms to address critical issues that often curtail effective implementation of development strategies and achievement of objectives. The process used to facilitate stakeholder participation and achieve enhanced understanding of collective actions to achieve objectives is illustrated by case studies in Niger and Burkina Faso. The process that determines the causal relationships among the various problems is also presented; results from the process can be used to determine …

What Are The Main Limits To Smallholder Livestock Production In The Tropics – According To Farmers?, A. J. Duncan

IGC Proceedings (1977-2023)

Livestock production is central to the livelihoods of a billion poor people. Transforming livestock production would have transformative effects on local economies in Sub-Saharan Africa and South Asia. Development efforts in the livestock sector have tended to be top-down without enough feedback loops to understand farmer realities and aspirations. This, despite the Farmer First movement that began in the 1990s. The Feed Assessment Tool (FEAST) was developed as a reaction to top down livestock feed development approaches. FEAST facilitates a structured conversation with farming communities about their livestock production system and how it connects with the overall farming system. FEAST …

A Systematic Review Of Ecological And Production Outcomes Under Rest-Grazing Systems, S. E. Mcdonald, R. Lawrence, R. Rader

IGC Proceedings (1977-2023)

With increasing pressure on grazing lands throughout the world, there is a growing need to balance sustainable management of livestock to meet food production and environmental impacts. Grazing management practices that incorporate periods of planned rest between grazing events (RG) may achieve both ecological and production goals simultaneously. We conducted a systematic review of global literature that compared ecological and production outcomes of RG systems with either continuously grazed (CG) or ungrazed (UG) areas. In addition, we evaluated the extent to which ecological and livestock production outcomes have been assessed simultaneously in these studies and identified future research needs. A …

Rejuvenation Of Rangelands – Role Of Diversity And Improvement Strategies Of Range Grasses, A. K. Roy, D. R. Malaviya, P. Kaushal

IGC Proceedings (1977-2023)

In India, a major part of the rural economy is dependent on the grazing-based livestock husbandry which is unique integration of agriculture and livestock coupled with rich traditional knowledge. Ecosystems of common property resources had been a mainstay in rural economy and livelihood. The traditional grazing forage resources in arid and semi-arid regions have deteriorated a lot due to various factors including heavy grazing pressure, climate change and dominance of invasive species, thus, needs rejuvenation. Additionally, these are causing serious economic and ecological problems such as poor productivity, soil and water erosion and reduced carbon sequestration.

Exploring Drivers Of Invasiveness Of The Plant Species Senna Obtusifolia In Rangelands To Secure Forage Production In West Africa, O. Ouédraogo, A. Zaré, C. Bougma, S. Kambou, A. Linstädter

IGC Proceedings (1977-2023)

Rangelands in Sahelian countries are continuously over-grazed decreasing forage resources and causing rapid environmental changes. Senna obtusifolia is a less palatable plant species that becomes increasingly invasive. This research explored drivers of its invasiveness in the perspective to propose solutions to secure forage production in the pastoral reserves. Species composition and herbaceous aboveground biomass were assessed in rangelands with different levels of invasion of Senna obtusifolia along a climatic and land-use pressure gradient. A greenhouse experiment was conducted to test the competitiveness of this species. The development of Senna obtusifolia in rangelands affected significantly forage quantity. Indeed the biomass of …
