Taking into account that renewable sources of energy can help to overcome these challenges and diversify the energy matrix in the countries, this paper aims at analyzing the biogas potential in Brazil and the United States, especially in the livestock sector, and its benefits in the environmental, social and economic aspects. Both countries are among the top five countries globally in terms of water availability, energy consumption and food production. Until 2050, the world consumption of meat will have a significant increase： 206% of poultry meat, 56% of pork meat and 47% of beef meat, augmenting the need for sustainable management of waste and manure. This scenario can become a sustainable opportunity for biogas implementation, which provides multiple economic, environmental and social benefits for farmers, businesses and communities, including production of electrical, thermal and vehicular energy, production of high-quality biofertilizer, reduction of ground and surface water pollution and reduction of GHG emissions, and foments new income for the farmers, among others. A new concept is presented in this article to make biogas systems feasible, i.e., biogas condominiums, as small and medium-scale farms by themselves usually would not be able to afford the investments. This arrangement can bring benefits for the whole biogas supply chain that includes farmers, agroindustry, providers and local community.展开更多

However, this development relates to natural resources depletion and deterioration of quality of life in rural population, especially in smallholder farmers. Thailand has practiced the New Theory Agriculture （NTA）, one application aligned with sufficient economy. This theory not only remedies damaged natural resources but also helps smallholder farmers to improve quality of life; and it is analogous to local food supply chain theory, that is well-known in western countries. However, NTA has not been measured its sustainability. Following sustainable food criteria and sustainable agriculture criteria, this paper uses an Indicator of Sustainable Agricultural Practice （ISAP） to measure sustainability at farm level of small rural community＇s network called Inpaeng, a case study that has practiced NTA. The result of assessment in this case implies that NTA yields sustainability to local food supply chain more than monocrop system.展开更多
