“…The International Food Policy Research Institute (IFPRI) uses consumptive use, rather than withdrawals in estimating livestock water demand. Return flows to the surface water and groundwater system are not calculated (Msangi et al, 2014). In PCR-GLOBWB and WaterGAP, livestock water withdrawal (= consumption, no return flow) is estimated by multiplying livestock numbers with water consumptive use per unit of livestock, including beef, chicken, eggs, milk, pork, poultry, sheep and goats.…”

Modeling global water use for the 21st century: the Water Futures and Solutions (WFaS) initiative and its approaches

Abstract. To sustain growing food demand and increasing standard of living, global water use increased by nearly 6 times during the last 100 years, and continues to grow. As water demands get closer and closer to the water availability in many regions, each drop of water becomes increasingly valuable and water must be managed more efficiently and intensively. However, soaring water use worsens water scarcity conditions already prevalent in semi-arid and arid regions, increasing uncertainty for sustainable food production and economic development. Planning for future development and investments requires that we prepare water projections for the future. However, estimations are complicated because the future of the world's waters will be influenced by a combination of environmental, social, economic, and political factors, and there is only limited knowledge and data available about freshwater resources and how they are being used. The Water Futures and Solutions (WFaS) initiative coordinates its work with other ongoing scenario efforts for the sake of establishing a consistent set of new global water scenarios based on the shared socio-economic pathways (SSPs) and the representative concentration pathways (RCPs). The WFaS "fasttrack" assessment uses three global water models, namely H08, PCR-GLOBWB, and WaterGAP. This study assesses the state of the art for estimating and projecting water use regionally and globally in a consistent manner. It provides an overview of different approaches, the uncertainty, strengths and weaknesses of the various estimation methods, types of management and policy decisions for which the current estimation methods are useful. We also discuss additional information most needed to be able to improve water use estimates and be able to assess a greater range of management options across the water-energy-climate nexus.

“…As vital links in the food chain, feed manufacturers and producers are having to give due consideration to changing social and economic climates (Chadd, 2008). Income growth in developing countries is driving strong growth in per capita and total meat consumption, leading to increases in feed consumption of cereals, particularly maize (Msangi et al, 2014). The South African broiler industry is a major consumer of maize, as it is the primary energy source used in broiler diets.…”

“…The mission of this network is to integrate research, education and extension, and land-grant universities have been especially critical of agricultural R&D by creating an effective avenue of communicating the most pressing concerns from farmers to researchers, and communicating solutions from researchers to farmers through the extension network (Nesheim et al, 2015). However, the database on livestock in developing countries, particularly in sub-Saharan Africa, has historically been fragmented and inaccessible, somewhat limiting potential livestock quantification (Msangi et al, 2014). A similar scenario is found in South Africa, where the database for small-scale and emerging poultry farmers does not provide conclusive evidence on the scale of production, product produced and markets.…”

Poultry meat and eggs are the largest source of animal protein in the human diet worldwide. These are the benefits of decades of poultry research investments that were aimed at developing fast-growing strains, a better understanding of nutrient metabolism and utilization, and the effects of those nutrients on gene expression. The South African poultry industry has advanced alongside global trends in most developed countries. The industry is dominated by a few fully integrated large commercial producers, and a high volume of small-scale producers, either as contract growers or individual producers supplying solely the informal market. Currently, the poultry industry is battling to remain competitive, owing to tons of imported dark chicken meat being dumped in this market by other countries at prices below the cost of production locally. This has had negative consequences on producers, big and small, and on the employment rate. Disease outbreaks, welfare regulations, food safety, house environment and a number of issues relating to nutrition and feeding are among current and future challenges to the poultry industry, particularly the smallscale segment. With urbanization escalating, land availability and accessibility for intensive poultry rearing, and crop production for feed will be a challenge. Simultaneously, although poultry has the lowest carbon and water footprint, global warming is likely to affect feed quality and quantity, increasing feed and energy costs, thereby influencing food security. In future, maize and soybean meal on a worldwide basis will remain the major ingredients in poultry diets, although research on feedstuffs for partial replacement of these two will still be relevant, more so for home mixers. Focus on poultry science education and training, research and extension partnerships between poultry scientists and veterinarians also needs serious attention. Lack of collaboration between the private and public sectors, and lack of innovative ways to articulate concerns from producers and consumers to policy makers remain barriers to technological adoption. This review adopts poultry in sole reference to chickens.

“…However, in Eastern Asian countries, animal production, which largely depends on imported concentrates, is easily affected by the variable and increasing tendency in imported price of feeds due to adverse climatic conditions in producing areas such as the corn belt in the United States, competition from bio fuel feedstuffs, a variable exchange rate and a fluctuating price of petroleum used in the operation of farm machinery (Msangi et al, 2014). One solution is to strengthen the production of selfsufficiency herbages by increasing yield or by increasing times of cultivation (multi-crop production).…”
