Integrated farming system producing zero emissions and sustainable livelihood for small-scale cattle farms: Case study in the Mekong Delta, Vietnam

Long An province, located in the Mekong Delta, has a large area of acid sulfate soils, of which tremendously high acidic soil of Thanh Hoa ward. Due to the toxic factors in the high acid sulfate soil, the area suffers the harsh natural conditions that leading to livelihoods limitation in terms of freshwater supply, drainage, agricultural cultivation, and environmental sanitation as well. The study approach is to build an integrated farming system based on the close loop of material and energy flows for a typical small-scale farm in acidic areas in Long An province for sustainable agriculture. Therefore, the potential systems meet the objectives of recycling waste by the energy efficiency analysis based on energy conversion and by the economic analysis. The results show that pig production and cultivated orchard obtain high profits. Energy efficiency from raising pigs accounts for a high proportion (50%) whereas the ratio of fish production and orchard has not reached 10%. Energy efficiency analysis implies the potential options with optimal efficiencies tend to biogas treatment and composting. In addition, the three-year lifetime system is more efficient than the one-year system. However, the household financial capacity plays the most important role in selecting for the suitable farming system as well as installation of treatment systems.

Important Cash Crop

Potatoes are an important cash crop for small-scale producers worldwide. The move away from subsistence to commercialized farming, combined with the rapid growth in demand for processed agricultural products in developing countries, implies that small-scale farmers and researchers alike must begin to respond to these market changes and consider post-harvest treatment as a critical aspect of the potato farming system. This paper presents and assesses a low cost potato-grading machine that was designed explicitly to enable small-scale potato growers to sort tubers by size for supply to commercial processors. The results of ten experiments reveal that the machine achieves an accuracy of sort similar to commercially available graders. The machine, which uses parallel conical rollers, has the capacity to grade different tuber shapes and to adjust sorting classes, making it suitable for locations with high potato diversity. Its relatively low cost suggests that an improved and adapted version of this machine might enhance market integration of small-scale potato producers not only in Peru, but in other developing countries as well.

ABSTRACT ANALYSIS OF INTEGRATED FARMING SYSTEM BETWEEN BEEF CATTLE AND RICE PADDY IN FARMERS GROUP OF KEONG MAS AT SANGKUB DISTRICT, NORTHBOLAANG MONGONDOW REGENCY (CASE STUDY). Integrated farming system of beef cattle and rice paddy is a combination of beef cattle fattening and rice paddy managed by “Keong Mas” Farmers Group. Feces and urine of beef cattle were materials to produce an organic fertilizer and paddy rice straw can be used as feed for beef cattle. The combination of fattening beef cattle and rice paddy straw has a purpose to create minimum cost and using of potential local resources. This research purpose was to evaluate the business profit and cost efficiency of “Keong Mas” integrated farming system. Research method used was study of case and observation as the information for collecting data. The result showed that profit of un-integrated fattening beef cattle were Rp. 9,780,000,- per 8 cattle per year. Un-integrated rice paddy gave Rp. 12,745,000,- profit per ha per year. The profit of integrated fattening beef cattle was Rp. 83,457,108 per 12 cattle per year and rice paddy was Rp. 90,517,250. Cost efficiency of un-integrated farming system was only 1.16 while integrated farming system gave cost efficiency of 1.49. Therefore, it can be concluded that the integrated farming system of fattening beef cattle and rice paddy in “Keong Mas” Farmers Group was profitable and efficient.
