The results show that cultivating new professional farmers can fundamentally relieve "three rural issues" existing for a long time and is of great significance to rural economic development. For instance, it can integrate rural human capital and release modern productivity, increase farmers' income and improve rural economy, increase land utilization and output per unit area, and break through the bottlenecks during agricultural development to realize agricultural modernization. According to the case study of Town S, during the process of cultivating new professional farmers, governments at all levels ought to adopt many effective measures and strengthen support to realize cultivation targets planed early.展开更多

This line produced a hypersensitive reaction to CYR34 and conferred resistance to 13 other pathotypes. Resistance to CYR34 in line 041133 was controlled by a single dominant gene. Bulked segregant RNA sequencing(BSR-Seq) was performed on a pair of RNA bulks generated by pooling resistant and susceptible recombinant inbred lines. Yr041133 was mapped to a 1.7 c M genetic interval on the chromosome arm 7 BL that corresponded to a 0.8 Mb physical interval(608.9–609.7 Mb) in the Chinese Spring reference genome. Based on its unique physical location Yr041133 differred from the other Yr genes on this chromosome arm.展开更多

We therefore need to explore and innovate a variety of ways of alleviating poverty among poor small-farm households. A project for 'poverty alleviation through nested market small-farm production' has been running for eight years in the villages of Taihang Mountains, Hebei Province. It started from the livelihood resources already possessed by small-farm households, then converted farm production of healthy agricultural products and local specialties into an 'industry' that took ordinary urban consumers’ demand for healthy foods as the corresponding exit point and nested markets as the organizational form of transaction and interaction. The trial shows that mutual trust and participation between the rural poor and the urban population has successfully transformed poor households’ livelihood resources and social capital into income, achieving accurate, stable and sustainable poverty alleviation and highlighting the concepts of innovation, coordination, and green and shared development.展开更多

Based on Sekaran sampling technique 306 respondents were selected and were personally interviewed through well prepared and pre-tested interview schedule. To find out the actual performance of yield improvement by Model Farm Services Center along with other repressors, step by step analysis was performed. The results of Wilcoxon Sign Rank Test showed significant improvement in yield of sugarcane, wheat, maize, rice and tomato by Model Farm Services Center. Pearson’s correlation coefficient showed highly significant positive relation of sugarcane and wheat yield difference before and after Model Farm Services Center registration with MFSC. Ordinary Least Square Multiple-Regression Model indicates that MFSC registration duration and landholding significantly define the variation in dependent variables at 1% and 5% level of significance respectively for sugarcane yield. Whereas solely Model Farm Services Center registration duration profoundly highly significantly (P ≤ 0.01) explains the variation in dependent variables in wheat yield.展开更多

The findings indicate that households with lower initial income level, higher share of wage income, higher educational level of household members, larger number of non-agricultural employed household members and younger heads are more mobile. Moreover, besides initial income, change in the share of wage income, change in the share of non-agricultural employed household members, and change in average year of education of household members are the most important factors that account for income mobility. These findings necessitate more emphasis on policies that promote non-agricultural employment and education to enhance household income mobility in rural China.展开更多

Flooding history shows that educational establishments have been disproportionately hard-hit by flooding events. In Pakistan, school safety and preparedness is still a choice, rather than a mandatory requirement for all schools. But schools in Pakistan do have a responsibility to keep safe the students in their care,especially during and after the catastrophic events. This implies the need to maintain the environment in and around school property, so as to minimize the impacts of floods and to have the mechanisms in place to maximize a school's resilience. This study examined the emergency preparedness activities of 20 schools in four districts of Khyber Pakhtunkhwa Province that had recently been severely affected by floods. Through face to face interviews and a structured questionnaire(n = 100) we collected data on the four pillars of emergency preparedness:emergency planning, preparation measures, safe school facilities, and hazard education and training. The study revealed that the majority of the sample schools hadexperienced more than one natural hazard-induced disaster,predominantly flooding, yet despite this had not undertaken adequate emergency preparedness activities. There are particular gaps with regard to plans for students with disabilities, the continuity of school operations after a disaster,the presence of maps to identify evacuation routes, the availability of emergency equipment and resources, disaster preparedness guidelines, and psychological first aid and crisis counseling. The strengths, weaknesses, opportunities,and threats analysis that our researchers carried out indicates that, although schools in the survey have taken many steps towards flood preparedness, many weaknesses still exist and there remain significant opportunities to strengthen the preparedness level of many schools. The goal of this study is to inform policy decisions that improve school safety in Pakistan and to suggest the priority areas for future school disaster preparedness and management efforts.展开更多
