Factors affecting biogas technology adoption behavior of pig-raising households: A case study in Hunan province, China

This paper discusses the factors affecting livestock farmers´ adoption of the biogas technology, using the Tobit model based on the pig-raising household survey in Hunan province. The results show that, biogas technology adoption behavior is negatively correlated with variables as householder´s gender and livestock price in the same year, showing that female householders are more interested in biogas technology, and a higher pig price will drive the adopters to expand farm scale but save biodigester costs; while the adoption behavior is positively correlated with variables as accesses to information, availability of off-farm income, householder´s attitude toward risks, farm scale in the same year, householders´ knowledge about animal waste and animal health, reception of governmental subsidy, aquaculture area, and actual amount of payment received.
