“…In Vietnam, parts of both liquid and solid manure produced by pig farms are applied to fish ponds and used to feed fish for local consumption (Vu et al, 2012). Modern technology, such as manure separation, anaerobic digestion, aeration, use of additives and inhibitors (Petersen et al, 2012;Zaman & Nguyen, 2012;Gebrezgabher et al, 2015;Kinyua et al, 2016), to treat manure and slurry from ruminates and nonruminants, may not represent a feasible option to reduce GHG emissions in developing countries. The main reasons are high costs, low accessibility, high technology required, lack of knowledge, and insufficient legislation.…”

Methane (CH 4 ) and nitrous oxide (N 2 O) are two important greenhouse gases (GHGs) that are emitted into the atmosphere by livestock during the process of enteric fermentation and manure management. Developing countries produce a large quantity of those emissions, caused mainly by inefficient animal rearing systems, feed production and manure management. This paper outlines the CH 4 and N 2 O emitted from livestock in developing countries and the mitigation actions that could be put in place to reduce atmospheric emissions and increase animal productivity. Emission intensity expresses emission (CO 2 equivalents) per unit of product and describes it in relation to the capacity of local animals to produce from local resources. Developing countries are characterized by low production per animal and, consequently, high emission intensity. The emission intensity of dairy cattle in developing countries ranges from 2 to 9 kg CO 2 -eq/kg fat and protein corrected milk (FPCM) and in only a few cases is below 2 kg CO 2 -eq/kg FPCM. In sub-Saharan Africa, the average emission intensity is 7.5 kg CO 2 -eq/kg FPCM for dairy cattle, 71 kg CO 2 -eq/kg of carcass weight for beef cattle, 6.9 kg CO 2 -eq/kg FPCM for sheep and goats, and 5 kg CO 2 -eq/kg eggs for chickens. Taking into account the limited economic and technical resources in most developing countries, the application of appropriate mitigation tools is recommended to reduce the emissions of CH 4 and N 2 O gases in the atmosphere. Increasing livestock productivity through selection and feeding is the most effective tool to reduce emission intensity. ______________________________________________________________________________________

“…On a global level, only few studies have specifically considered manure and the use of organic fertilizers by farmers and professional consultants (Gebrezgabher et al, 2015). Although South America accounts for 54% of the livestock and 5% of the dairy cows in the world (FAOSTATS, 2016), there are no published studies on these issues.…”

Milk production is important in South American countries being based mainly on grazing systems. Dairy slurry management has become an important issue in these production systems because of the large volumes produced and the environmental effects. Thus, manure management regulations are emerging in the region. This research aims to identify priorities for management strategies and technology transfer by assessing perceptions, needs and barriers toward dairy manure management by stakeholders in South American countries. A questionnaire was prepared and distributed in Spanish and Portuguese in different formats: on paper and online (PDF format and SurveyMonkey TM platform) between March 2015-November 2017. It was divided into two sections, the first addressed issues related to water quality and pollution, odor generation, fertilizer value, pathogens impact and biogas production. Responses were measured across a standard 5-point Likert type scales. Section two addressed needs and hindrances concerning about manure application. A total of 593 surveys were completed: Argentina (n = 308, 52%), Brazil (n = 217, 37%) and Chile (n = 68, 11%). The majority of respondents were dairy farmers (31%), professional advisors and consultants (29%) and representatives of public institutions and researchers (31%). Some differences appear according the country. Overall, a large majority perceive that manure is a good fertilizer (91%), also they believe that it contributes to pathogen's transmission and groundwater and shallow aquifers 'contamination. Stakeholders (60%) perceived biogas production as a good option for manure treatment. Most of respondents (79%) would use manure to replace mineral fertilizers, with little differences between countries (Argentina 79%, Brazil 80% and Chile 68%). The most selected needs were: a management handbook, increased investment in equipment and technologies and better access to laboratory analysis. The most chosen barriers were: cumbersome management, lack of knowledge and of specific laws, with differences between countries and respondents. The survey showed interest in dairy manure management as a source of nutrients for grassland and crops, especially among farmers and advisors whom requested Herrero et al.South American Dairy Manure Management Perceptions guidelines for responsible management. Policymakers and stakeholders should focus on promoting manure reuse on dairy farms through incentives, technologies and/or appropriate strategies, in order to improve nutrient use and reduce pollution to the wider environment.

“…A number of variables can affect net cash flows, including farm size, farm location and extension services. Regarding farm size, larger farms have more potential to achieve economies of scale (Pannell et al 2006;Gebrezgabher et al 2015). As a result, larger farms tend to achieve a lower long run average cost than smaller farms.…”
