    Yield gap analysis of field crops. Methods and case studies 2015
    Also available in:

    The publication “Yield gap analysis of field crops: Methods and case studies” reviews methods for yield gap analysis, clarifying definitions and techniques to measure and model actual, attainable and potential yield at different scales in space and time and using case studies to illustrate different approaches. The publication is a contribution to advance global water and food security through improvements in water and land productivity. It discusses methods to measure yield gaps, and ways to diagnose the root causes of yield and water productivity gaps and the actions that will be needed to close yield gaps in both small and large scale cropping systems, including management options and policies to provide incentives for the adoption of gap-closing technologies.

    Study on residents’ willingness to accept based on double-bounded dichotomous CVM: a case study of Qianjiangyuan National Park pilot, China

    This study, by taking Qianjiangyuan National Park Pilot as an example, was to analyze community residents' willingness to accept(WTA) for ecological benefits, and the influencing factors, so as to provide some reference for the future policy. Questionnaire survey was conducted on the spot. Guided by the double-bounded dichotomous contingent valuation method (CVM), this study calculated WTA and analyzed its influencing factors. The estimated WTA is 155.37 yuan RMB per mu per year, which is much higher than the current compensation implemented in this area. Respondents' family characteristics (including the number of household labor force, agroforestry income proportion, location, etc.) are more important and significant in their WTA decision-making. The respondents' cognition towards the National Park also affected their choice of WTA. Most of the respondents agreed that the priority goal of the National Park is "ecological protection", and the preferred WTA of the respondents who have this recognition will also be reduced. However, there are still some community residents who do not know the National Park clearly. Therefore, it is necessary to further strengthen the publicity and education work of the National Park to enhance residents' awareness. Keywords: community residents; WTA; double-bounded dichotomy; logistic multiple regression; Qianjiangyuan National Park ID: 3486150

    Empirical study on the effects of technology training on the forest-related income of rural poverty-stricken house-holds—based on the PSM method

    The implementation of technology training is essential to promote the commercialization of research achievements, and plays a crucial role in poverty alleviation in China. Based on the microcosmic survey data of farmers in four poverty-stricken counties officially assisted by National Forestry and Grassland Administration,the effects of technology training on forest-related income of rural poverty-stricken households is analyzed by using Propensity Score Matching (PSM) method. The study found that after eliminating the deviation from the self-selection and the endogenous issues, the forestry technology training has increased the total forest- related family income and forestry production and operation income by 3.09 times and 2.82 times, respectively. The effect of technology training on income increase is remarkable. Besides, the behavior of poor farmers participating in forestry technology training is significantly affected by the following factors, such as gender, age, family size, managed forestland area, whether they held forest tenure/equity certificate, whether they joined forestry professional cooperatives, and whether they cooperated with forestry enterprises. In order to further improve the effect of technology in poverty alleviation, the following policy recommendations are proposed, including: (1) to encourage poverty-stricken households to actively participate in forestry technology training; (2) to establish a diversified system of forestry technology training; and (3) to ensure the training content is based on the actual needs of the poor. Keywords: rural poverty-stricken household; technology training; forest-related income; PSM method ID: 3487078
