Download The Livestock-Water Nexus Under Mixed Crop-Livestock Production System Book in PDF, Epub and Kindle
Livestock production is growing and shall continue to grow to match the demand for an ever increasing human population for livestock products and services. Water is one of the limited resources and crucial input for livestock production. Literally the actual need of livestock for water is not well accounted for more than their drinking requirements, which is much less than the actual requirement. On the other hand there is competitive use of water across different users. Under mixed farming systems, integrating livestock production into water resource development has delivered synergistic benefit. Water-efficient agricultural practices are becoming mandatory owing the growing water scarcity. In this regard management of livestock-water interaction in mixed crop livestock systems will contribute to increased water use efficiency for food production and ecosystem services. It would, therefore, be necessary to understand and evaluate the existing livestock and water nexus. This material tried to explore the water productivity determination models. It will be useful particularly for agriculture, natural resource, environmental and livestock science professionals and policy makers.

Download Livestock and water interactions in mixed crop-livestock farming systems of Sub-Saharan Africa: interventions for improved productivity Book in PDF, Epub and Kindle
Focusing on mixed crop-livestock farming systems of sub-Saharan Africa, this review brings together the available knowledge in the various components of the livestock and water sectors. Through an analysis of livestock-water interactions, promising strategies and interventions to improve Livestock Water Productivity are proposed. In the biophysical domain, the numerous interventions relate to feed, water and animal management. These are interlinked with interventions in the socio-political-economic domain. The paper identifies critical research and development gaps in terms of methodologies for quantifying water productivity and integrating different scales, and also in terms of institutions and policies.

Download Accounting for livestock water productivity: How and why? Book in PDF, Epub and Kindle
The assessment of water productivity in livestock supply chains has a critical role to play in developing productive and sustainable food production systems worldwide. In particular, the evaluation of water productivity improvement options is key to addressing growing food demand and the projected impacts of climate change under conditions where the availability of land and water resources is increasingly limited. In this report, we review current applications of water productivity analysis in livestock supply chains. To do so, we analysed 50 livestock water productivity studies carried out in various regions of the world from 1993 to the present time. We reviewed the assessment goals, system boundaries, methodological approaches, water flows, modelling tools, databases, livestock species and the main findings in each of the studies. We found that there was no consistency in the methods and approaches used to assess water productivity in livestock production chains. The studies varied widely in terms of their assessment goals, methodology, and the sources of water used for the analysis. The main methodological differences were the inclusion or exclusion of background processes, such as water input and the treatment of precipitation in accounting for water use in livestock production processes. Another key issue was the missing uncertainty assessment, which can be classified as input data uncertainty or model uncertainty, as well as choice uncertainties. The review recommends the further development of guidelines that ensure a consistent and coordinated application of water productivity analysis of livestock production systems world-wide.

Download Water use in livestock production systems and supply chains. Guidelines for assessment Book in PDF, Epub and Kindle
The Technical Advisory Group (TAG) for Water Use Assessment, composed by 30 international experts, has developed guidelines on water footprinting for livestock supply chains. The mandate of the Water TAG was to provide recommendations to monitor the environmental performance of feed and livestock supply chains over time so that progress towards improvement targets can be measured; apply the guidelines for feed and water demand of small ruminants, poultry, large ruminants and pig supply chains; build on and go beyond the existing FAO LEAP guidelines; and pursue alignment with relevant International Organization for Standardization (ISO) standards, specifically ISO 14040, ISO 14044 (ISO, 2006b and 2006a) and ISO 14046 (ISO, 2014). The guidelines on water use assessment include the impact assessment: the assessment of the environmental performance related to water use of a livestock-related system by assessing potential environmental impacts of blue water consumption following the water scarcity footprint according to the framework provided by ISO 14046 (ISO, 2014); and the assessment of the system’s productivity of green and blue water. The guidelines are thus intended to support the optimization of use of water resources and the identification of opportunities to decrease the potential impacts of water use in livestock production. The Water TAG guidance is relevant for livestock production systems, including feed production from croplands and grasslands, and production and processing of livestock products (cradle-to-gate). It addresses all livestock production systems and livestock species considered in existing LEAP animal guidelines: poultry, pig, small ruminant and large ruminant supply chains.

Download Livestock Production and Climate Change Book in PDF, Epub and Kindle
In a changing climate, livestock production is expected to exhibit dual roles of mitigation and adaptation in order to meet the challenge of food security. This book approaches the issues of livestock production and climate change through three sections: I. Livestock production, II. Climate change and, III. Enteric methane amelioration. Section I addresses issues of feed quality and availability, abiotic stress (heat and nutritional) and strategies for alleviation, livestock generated nitrogen and phosphorus pollution, and approaches for harnessing the complex gut microbial diversity. Section II discusses the effects of climate change on livestock diversity, farm animal reproduction, impact of meat production on climate change, and emphasising the role of indigenous livestock in climatic change to sustain production. Section III deals with the most recent approaches to amelioration of livestock methane such as breeding for low methane emissions, reductive acetogenesis, immunization/vaccine-based concepts and archaea phage therapy.

Download Livestock Farming at the Expense of Water Resources?$nThe Water–Energy–Food Nexus in Regions with Intensive Livestock Farming Book in PDF, Epub and Kindle
Policymaking in the water–energy–food nexus is characterized by complex ecological, social, and economic interdependencies. Nexus research assumes these interactions to be overseen in the respective resource governance resulting in sectoral perspectives contributing to unsustainable outcomes. In Germany, the political priority given to the formation of an internationally competitive livestock sector by means of intensification, specialization and regional concentration has exerted sustained pressure on water and soil resources. The expansion of bioenergy plants promoted by the renewable energy act has exacerbated the situation. Despite the persistency of the ecological challenges, German policymakers only reacted when the European Commission referred Germany to the European Court of Justice. Current policy eorts to tackle the ecological problems are now provoking disruptions in the agrarian sector in regions with high nitrate concentrations in water resources. By combining the social-ecological systems framework with hypotheses derived from nexus research, we explore the interactions between food, water and energy systems and aim at understanding the unsustainable outcomes. We argue that the non-consideration of the complex interdependencies between the agricultural, the water and the energy system in policymaking and the divergence of policy goals constitute a major cause of unsustainable governance.
