农业发展问题是一个影响中国工业化、城市化和现代化建设的根本性问题。农以土为本，农地资源及其利用状况对于区域发展影响重大。文章以湖北省为例，从农地资源的自然属性、人口技术属性和经济属性等方面对瑚北省农地资源时综合质量进行评价。得出湖北省农地资源质量居中的基本结论；以农地利用分区为基础。对湖北省各分区农地资源的组合状况和综合质量进行了评价排名；最后又对湘北省农地资源利用状况进行评价，并根据各评价结论提出了湖北省合理利用农地资源。发展农业经济的基本策略。     

Public Investment and Environmental Sustainability of Agricultural Production in China

The excessive application of fertilizer and pesticides in grain production in China has posed a threat to the environmental sustainability of agricultural production. One of the major reasons of the increasing usage of chemical inputs by farmers is their trying to reach higher yields, especially in absence of adequate public inputs, such as development and extension of appropriate technology and necessary production infrastructure, etc. Based on the crop specific data of the past 20 years, this paper examines how the public investments in agricultural researches could impact on the reduction of farmers' private material inputs of major grain crops in China. It manifests that the increased investments in public sector, especially in agricultural researches, is a favorable and effective way to reduce farmers' private material inputs and should be given a priority consideration in the policy emendation to increase yields and improve production sustainability.     

Economic assessment of producing a fluting paper using agricultural residues – a case study: Iran,Mazandaran Province

Given limited forest resources and increased paper consumption and imports, establishing fluting paper mills using non-wood raw materials seems more essential than ever. This paper aims to investigate, technically and economically, the possibility of establishing a fluting paper mill (with a capacity of 10,000 tons a year) from agricultural residues in Iran's Mazandaran province. The average annual agricultural residues output (including wheat, barley, rice, corn, oil seeds and cotton) in the province was about 1.3 million tons from 2000 to 2010, showing the potential of the province as an appropriate source for providing raw material from agricultural residues. For economic evaluation of the project, economic indices such as rate of return, pay-back period and production break-even point were measured. The results indicated that establishing a fluting paper mill based on agricultural residues is feasible.     

畜禽粪肥还田四环素类抗生素(TCs)在土壤-蔬菜系统的分布特征及风险评估

畜禽粪肥还田引起的土壤抗生素污染对蔬菜安全和土壤生态风险的影响应得到足够的重视.四环素类抗生素(TCs)在畜禽粪肥和蔬菜基地土壤中被普遍检出且含量较高.然而,目前针对土壤TCs污染对蔬菜安全和土壤生态风险的研究主要采用盆栽试验和田间调查的研究方法,较少开展田间试验.结合盆栽试验和田间试验的研究方法,调查畜禽粪肥还田引起的TCs在土壤-蔬菜系统中的分布特征,采用日允许摄入量-危害商值法(ADI-HQ法)和物种敏感性分布-风险商值法(SSD-RQ法)分别对蔬菜可食部分TCs污染的人体健康风险和土壤TCs污染的生态风险进行评估.结果表明,盆栽试验和田间试验菜心地上部和地下部TCs含量均以OTC为主;盆栽试验和田间试验菜心地上部(以干重计)ω(OTC)分别高达29.25μg·kg^-1和45.03μg·kg^-1,地下部含量(以干重计)ω(OTC)分别高达87.32μg·kg^-1和135.44μg·kg^-1;且田间试验菜心地上部和地下部3种TCs含量均显著高于盆栽试验.土壤TCs的残留以OTC为主,盆栽试验和田...

The value content of agricultural technologies and their effect on rural regions and farmers

The premise of this article is that technologies are not neutral in terms of their design objectives, their scale, and the fact that they reflect the physical and social environments in which they have developed. Specific agricultural technologies, the midwestern plow, the California tomato harvester, and various biotechnologies, are evaluated in these terms and shown to have generally predictable impacts upon rural regions and farmers. Finally, the article examines a series of major threats such as climate change that require the rethinking and restructuring of agriculture along more sustainable lines, something the can be accomplished only with a conscious recognition of the non-neutrality of technologies.This article was prepared for the conference Ethical Choice in an Age of Pervasive Technology, University of Guelph, October 25–29, 1989.     

On Sustainable Development of Social Forestry in Bangladesh: Experiences from Sal (<Emphasis Type="Italic">Shorea Robusta</Emphasis>) Forests

Sustainability in forestry is a complex amalgam of trade-offs among its various dimensions and there is no easy route to achieve sustainable development. It is important that policy process and implementation strategy of these policies should be based on sound information about these trade-offs. There is a growing consensus amongst key forest decision-makers in Bangladesh that traditional forestry is needed to make the transition to more sustainable forestry, which is likely to involve local people in forest management. As a result, the government has initiated a social forestry program from 1981 with the assistance of the Asian Development Bank (ADB) loan and the United Nations Development Program (UNDP) grant and operated mainly in Sal forest areas. The most important objective of this program is to protect, manage, and develop forests in a sustainable way by involving local communities. Although several studies have focused on the management issues of social forestry, none of these studies has evaluated the indicators of sustainable social forestry. The purpose of this study is to evaluate the criteria of sustainable development of social forestry in Bangladesh. The study is based on primary cross-sectional data collected using the multistage stratified sampling technique. In total, 581 social forestry farmers were selected randomly and interviewed using a pre-tested questionnaire. The study evaluated some important components of sustainable development and identified the following conditions of social forestry in Bangladesh:(i) almost all the components of sustainable development of social forestry, although not at the aspiration level, were at good condition;(ii) participants were interested and committed to work with Forest Department in developing social forestry;(iii) they had been utilizing both hard and soft technology in practicing social forestry, although there exists ample scope of development;(iv) income of participants after involving in social forestry had increased, although not at satisfactory level; and(v) process of producing social and material goods had been under progress.However, there exist plenty of scopes for sustainable social forestry development through improving the sustainable development components more carefully.Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.
