Résumé partiel
In view of the optimum effect for a farmer household to be a micro-economic individual, with the theoretical analysis of economics, sociology, and the quantitative analysis, this paper evaluates the determinants of farmers’decisions to adopt " Rainwater harvesting and supplementary irrigation technology (RHSIT) "、" Pasture-crop rotation (PCR)"、" Shed-feeding"、"Grain-for-Green project" and its elasticity of adoption in the rain-fed farming systems in the semiarid areas of Loess Plateau.The paper selects decisive variables in order to provide micro-theoretical evidence for sustainable development in the semiarid areas. Some concludes and suggestions are as follows:Fanners are full rational, their adoption decision for technologies and polices is the results of their livelihood within specific conditions and social economic structures in the semiarid areas.The results indicate that 12 variables are significant in explaining farmers’ adoption of RHSIT. Farmers’ educational background,active labor force size, contact with extension, participation in the Grain-for-Green project,and positive attitudes towards RHSIT、the diversity of irrigated crops are some of the variables that have significantly positive effects on adoption of RHSIT, while farmer’s age and distance from water storage tanks to farmers’ dwellings have significantly negative correlation with adoption. The probability of adoption also increases with increased targeting of institutional variables : credit obtained, assistance obtained, and technical training received. Farmers in villagesthat have more erosion problems are more likely to adopt RHSIT. Variables such as family size, off-farm activity, level of family income, risk preference, and land tenure do not significantly influence adoption. This information will help prioritize the factors that affect adoption decisions and provide insight on pathways to increase the adoption of RHSIT.Using a logistic regression model, this paper evaluated the determinants of adoption of PCR among smallholder farmers in rain-fed farming systems in the Loess hilly area of the Loess Plateau. Results indicated that socio-economic characteristics of the farmers, and farm related factors and institutional factors, significantly affect their decision regarding adoption of PCR. Firstly, the age of the farmers, the size of their family, the number of ruminants owned, and the fanners’ attitudes towards PCR have significant positive effects on the adoption of PCR, where the level of the family income is negative. Secondly, the slope of the field, and fallow practice variables also play a critical role in the adoption of PCR, suggesting the importance of targeting the promotion of PCR to farmers in areas with problems of soil erosion. The analysis also showed that farmers’ perception of the problem of soil erosion is positively correlated, having the most significant impact with the highest estimated elasticity. Thirdly, the institutional variables, which are represented by contacts with extension workshops, a participatory approach, the credit and training facilities obtained, and participation in the Grain-for-Green project (PGFG) all have significant positive effects on the adoption of PCR. On the other hand, participation in the rainwater-harvesting project and in the supplementary irrigation project did not show any correlation to the adoption of PCR by farmers.With the Logistic regression, this paper evaluates some social economic factors for farmers to adopt shed-feeding technology, the conclusions are : the higher the farmers’ educational level and the more the farmers’ numbers of work power, the easier for farmers to adopt shed-feeding technology ; there are more arable lands, there are preferable conditions for Grain-for-Pasture. Whether or not farmers are satisfied with the shed-feeding technology, it depends on the effective results of application with the shed-feeding technology ; the economic effects are fundamental reasons and drivers for farmers to adopt technologies. The principles for preferable economic benefits and basic ecologic effects should be followed and it is quite material for farmer to promote their management, technologies. Both the low-income and shortage of funds result in the failure for farmer to adopt the shed-feeding, there are obvious effects in fuel variables on farmers. So factors such as fuels, forages are preferable conditions for the development of shed-feeding, or the utilization of technology will meet the reaction of livelihood reality. In respect of results, without the application of improved breeding sheep, fanners would have no interesting
