The model applies ecological solutions, revolving solutions, and closures of energy flows along with utilizing the local environmental conditions available to help maintain livelihoods for the people. Typical models for Mr. Nguyen Van Hai households in Trung An hamlet, Le Tri commune, Tri Ton district, An Giang province. The results show that 3.18 m3 /day of livestock and domestic waste water is treated and reused for agriculture, 39,065.31 tons of CO2tđ/year is collected in the form of biogas for cooking, models help to maintain existing livelihoods, creating a number of new livelihoods to increase income of VND 64,400,000/year, ensuring environmental protection requirements, reducing existing livelihood dependence on external actors such as price, food, human resources, etc. This can be considered as the best model for cow farmers
can overcome the disadvantages of previous local livelihood models
Both in terms of long-term applicability, as well as the development of a large number of households, there is an increase in the ability to connect among households in order to create mutual support in the case of a residential area with the same main livelihood as livestock cow.
