“…In Asia, manure is considered a valuable resource, and is used as organic fertilizer, in biogas production, and as biofuel. In Latin America, recycling of manure is not diffuse owing to availability of cheap industrial fertilizer, deforestation and subsequent expansion of agriculture on fertile land, and a rotation system with the possibility of letting the soil regenerate for a few years (Thien Thu et al, 2012;Herrero et al, 2013). Large differences in manure management can be seen between countries in the same continent.…”

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. ______________________________________________________________________________________

“…Besides that, it turned out that in households having biogas digesters some surplus of biogas was generated which exceeded the families demand, according to a survey of Thien Thu et al (2012). Thus, in order to reduce investment costs and avoid surplus methane emissions, the necessary amount of feed loaded into the biogas tank is calculated.…”

“…Among the barriers, the most important ones are investment and operation costs of waste treatment facilities (T. H. Le, 2015) -for instance, investment cost for 1m 3 seafood processing wastewater is approximately 1,000 US$ -thus, an appropriate model which overcomes those barriers is highly required. For the small scale livestock farms (30 -50 pigs), lack of biogas plants can be explained by the lack of household budgets (Thien Thu et al, 2012), and most of the households in the craft villages therefore do not apply any waste treatment measures (K. C. Dang, 2005;T. H. Le, 2015).…”

“…However, the direct discharge into the environment is also common in Vietnam and other developing countries (Thien Thu et al, 2012). According to the regulations in some countries, the wastewater from livestock farms must be treated as done with the national technical regulation on industrial wastewater.…”

“…Moreover, for the larger livestock farms (i.e. over 100 pigs), quantity of biogas produced is exceeding the needs for cooking and lighting in the family, which leads to methane emission into the environment (Thien Thu et al, 2012), wasting the renewable energy and increasing green house gases emission.…”

This critical review examines the potential of household biogas technology in Africa, focusing on biogas production and techno‐economic feasibility studies. The review highlights the benefits of biogas technology, including renewable energy generation, waste management, and improved public health. A significant portion of Africa's rural population, approximately 60%, grapples with limited access to reliable power sources. The study analyzes various biogas production systems, including anaerobic digesters and biomass gasifiers, and evaluates their economic viability in different African contexts. The review identifies key factors influencing the adoption of household biogas technology, including policy and regulatory frameworks, financing mechanisms, and public awareness. Biogas production stands out as one of the promising renewable energy sources. However, it also discusses the challenges and limitations of implementing this technology on a continental scale. The study analyzes various biogas production systems, including anaerobic digesters and biomass gasifiers, and evaluates their economic viability in different African contexts. The review identifies key factors influencing the adoption of household biogas technology, including policy and regulatory frameworks, financing mechanisms, and public awareness. The study concludes by recommending strategies for scaling up biogas technology in Africa, including capacity building, technology transfer, and innovative financing models. The review aims to provide a comprehensive resource for researchers, policymakers, and practitioners working towards sustainable energy solutions in Africa.
