According to the Food Agriculture Organisation (FAO), world food production must increase by 50% within the next 20 years, while 80% of that increase must come from the intensification of agricultural production. The global livestock sector is growing faster than any other agricultural sub-sector. While livestock production forms one of the pillars of the EU food industry it faces many societal challenges, not least from the rising demand for meat protein, increasingly stringent environmental regulations, coupled with the falling numbers of young farmers entering the industry. Modern farm animal production is increasingly regarded as a source of solid, liquid and gaseous and dusts emissions which can be both a nuisance and environmentally harmful. The main objective of LivAGE Action is to enhance international discipline cooperation for exchanging ideas and knowledge, sharing good practices, assess technologies that could result in reducing the emissions of GHGs and ammonia from livestock buildings and thus to lead to a more environmental friendly and sustainable livestock production. The role of nutrition and productivity will be also taken under consideration. The results will be made readily available in order to significantly enhance awareness in the livestock sector of the current hazard level and the perspectives related to the future. Some secondary objectives are the estimation of emission factors, the impact of the applied diets, prevailing microclimate and ventilation schemes on emissions, the assessment of integrated monitoring systems, the improvement of CFD applications, the assessment of mitigation techniques and the environmental analysis of the proposed techniques and solution.
