Modernized Development of Urban Farming Industry: A Case Study of Kunming City

Modern urban farm is an essential part of urban agriculture and is inevitable trend of social economic development of modern cities.Based on empirical study of Kunming City,this paper analyzed current situations and difficulties of urban farming industry,explored development idea of urban farming industry,and came up with recommendations from institutional innovation,overall planning,property right reform,infrastructure construction,and talent team cultivation.

The Innovation System Dynamics of the Shrimp Farming Industry in Northeastern Brazil

The present article is an analysis of the innovation system dynamics of the shrimp farming industry in Northeastern Brazil along with the forms of interaction and exchange of information and know-how and the generation and diffusion of innovation characterizing its development. Brazil is the world＇s tenth-largest shrimp producer, with farms strongly concentrated in the Northeastern part of the country. Our findings show that the shrimp production/innovation system in Northeastern Brazil is highly institutionalized and is regulated, controlled and inspected by government agencies. In addition, the sector is now strongly networked with public universities, training and research institutions and other entities with varying degrees of autonomy and different forms of cooperation and integration. Parts of the technological innovations adopted by large companies in the sector are a spin-off of activities at universities and research centers. However, the close cooperation between public research/teaching institutions and large-scale producers is rarely extended to small and midsize businesses, whose interrelations become very fragile. The lack of communication between small producers and public research/teaching institutions makes it more difficult for farmers to assimilate new processes and to generate and incorporate innovations, compromising the dynamics of the production/innovation system of the shrimp farming industry in Northeastern Brazil.

The Development and Communicative Strategy of Recreational Farm Industry （RFI）： A Case Analysis of Taiwan

Farm tourism with recreational farm industry （RFI） is often considered as an economic alternative for farmers who are facing decreasing profits and might require another form of revenue. Compared with other industries, the most obvious advantage and benefit of RFI are not only economic incentives but environmental sustainability. Due to the increase in governmental income and global economic recession, RFI became an important way to broaden profit base for many governments. Recently, the successful RFI development in Taiwan is well-known. This research discussed the situation and main advantages of RFI, and mainly reviews RFI development/communicative strategies in Taiwan as a case study. This research finds the key success factors are： building the single window service scheme, development of creative value, build up the marketing routes of leisure industries scheme, improve the quality and service of recreational farming products scheme, and putting into series advertisement.

Influence of industrial organizational structure on farming performance of large yellow croaker farmers

This paper determines the cost-benefit levels of yellow croaker farming households by comparing and analysing responses to questionnaires distributed to 405 households located in nine breeding regions of three counties(cities)in the Chinese provinces of Fujian and Zhejiang.A transcendental logarithmic stochastic frontier production function model is used to perform a quantitative analysis on the large yellow croaker production technique efficiency of different forms of industry organisation,with the farming household as the basic production unit.The findings indicate that the average production technology efficiency of the farming households is 84.33% and room for improvement remains;and there are significant differences between the production technique efficiency of farming households from different regions and under different forms of organisation.An analysis of the factors that affect farming household production technique efficiency found that capital input has a greater effect than labour input.Family participation and the number of individuals involved in the rearing of large yellow croakers,participation in technical training,and joining a closely-knit industry organisation all have a significant positive effect on increasing the production technique efficiency.These empirical results provide a basis and practical reference for optimising the development of the large yellow croaker farming industry,enhancing the degree of closeness of the organisations in the industry,and improving aquaculture performance.

NUTRIENT USE EFFICIENCY AND LOSSES OF INDUSTRIAL FARMS AND MIXED SMALLHOLDINGS:LESSONS FROM THE NORTH CHINA PLAIN

The proportion of industrial livestock in China has increased over the past 30 years,which increases animal performance but causes the decoupling of crop and livestock production.Here,we aimed to quantify nutrient flows,nutrient use efficiency,and nutrient losses in different livestock systems in the North China Plain based on the NUFER-farm model.Activity data were collected by face-to-face surveys on pig and dairy(41 livestock farms)during 2016-2018.The two systems included industrial farms and mixed smallholdings.In mixed smallholdings,4.0%and 9.6%of pig and dairy feed dry matter(DM)were derived from household farmland,but 4.8%and 9.3%of manure DM recycled to household farmland.Nutrient use efficiency in industrial farms was higher than in mixed smallholdings at animal level,herd level,and system level.To produce 1 kg N and P in animal products,nutrient losses in industrial pig farms(2.0 kg N and 1.3 kg P)were lower than in mixed pig smallholdings,nutrient losses in industrial dairy farms(2.7 kg N and 2.2 kg P)were slightly higher than in mixed dairy smallholdings.Liquid manure discharge in industrial farms was the main losses pathway in contrast to mixed smallholdings.This study suggests that feed localization can reduce nutrient surpluses at the district level.It is necessary to improve manure management and increase the degree of integrated crop-livestock in smallholdings.In industrial farms,it is desirable to increase the liquid manure recycling ratio through cooperating livestock and crop production at the district level.
