    China’s Ecological Agriculture: Progress and Perspectives
    LI Wenhua, LIU Moucheng, MIN Qingwen
    Journal of Resources and Ecology    2011, 2 (1): 1-7.   DOI: 10.3969/j.issn.1674-764x.2011.01.001

    Agriculture is the basis of national economy.Through science and technology and the intensive utilization of land,great achievements have been made in agriculture.However,some agro-ecological and environmental problems are rising.Because of this,people have begun to reflect on agricultural developmental policy,patterns and technologies,and put forward new thoughts for agricultural development.In the late 20th century,China’s ecologists and agronomists co-sponsored the concept of ecological agriculture with Chinese characteristics.Its essence includes a series of concepts such as integration,coordination,circulation and regeneration within agroecosystems or within systems of agriculture production,processing and marketing.After nearly 30 years of practice and development, ecological agriculture in China has achieved remarkable outcomes.However,current eco-agriculture development is unsatisfactory due to the following two factors:(i)A lack of research and accounting across a variety of agro-ecosystem service functions;(ii)It is difficult to obtain remarkable economic benefits because of the lack of market-oriented guidance,scale management,specialized production and brand popularization for the traditional autarkic peasant economy.In order to further promote the development of ecological agriculture it is necessary to engage in serious reflection on ecological agriculture in China and arrive at new understandings about circular economy,multifunctional agriculture,high-quality agriculture, industrial development,integration of the traditional essence and modern technology,and finally,the sustainable development of rural areas.

    Ecoagriculture in China:A Systems Approach
    LUO Shiming
    Journal of Resources and Ecology    2011, 2 (1): 8-14.   DOI: 10.3969/j.issn.1674-764x.2011.01.002
    Abstract198)      PDF (1499KB)(24)      
    Ecoagriculture in China began in the late 1970’s/early 1980’s.This system aims to bring about the most effective coordination of social,economic and ecological factors in agricultural practices.Key approaches include ecological planning at the landscape level,cycling system design at the ecosystem level,and the re-establishment of the importance of biodiversity.The social and economic environment favoured for ecoagriculture is important in order to enable its development.For the social environment, it is important to set up the necessary moral standards involved through educational,legislative and evaluation systems.For the economic environment,efficient government subsidy policies,an effective market system to deal with pollutant discharge,and efficient markets for the sale of ecologically-friendly products.

    Agricultural Heritage Research in China: Progresses and Perspectives
    MIN Qingwen, HE Lu, ZHANG Dan
    Journal of Resources and Ecology    2011, 2 (1): 15-21.   DOI: 10.3969/j.issn.1674-764x.2011.01.003
    Abstract148)      PDF (638KB)(25)      
    One of the legacies of the time honored agricultural development in China has been varied farming practices that adapt well to different natural conditions.These old but still functioning farming systems continue to inspire us to find solutions to various environmental problems caused by so-called modern agriculture.This paper reviewed the studies on agricultural heritage in China,including two categories: document-based researches and practice-oriented researches on dynamic conservation and adaptive management of these traditional agricultural heritages.Studies on the history and archaeological findings about the Chinese traditional agricultural heritage have laid a solid foundation for any further study. Dynamic conservation and adaptive management of agricultural heritage was promoted by the Globally Important Agricultural Heritage Systems(GIAHS)project initiated by FAO in 2002.Until now,researches on the conservation and adaptive management of agricultural heritages have touched on many aspects of the issue,including theoretical consideration of agricultural heritage,agrobiodiversity characteristics of agricultural heritage,multi-values of agricultural heritage dynamic conservation,substitutive industries, legislation and institutionalization for the conservation of agricultural heritage.We conclude the paper with an agenda for future studies on agricultural heritages,including the broadening of the research scope,innovative research methodologies and methods and the development of strategies that combine conservation and utilization of agricultural heritages.

    Conservation and Adaptive Management of Globally Important Agricultural Heritage Systems(GIAHS)
    Parviz KOOHAFKAN, Mary Jane dela CRUZ
    Journal of Resources and Ecology    2011, 2 (1): 22-28.   DOI: 10.3969/j.issn.1674-764x.2011.01.004
    Abstract196)      PDF (635KB)(89)      
    Worldwide specific agricultural systems and landscapes have been created,shaped and maintained by generations of farmers and herders based on diverse natural resources using locally adapted management practices.Building on local knowledge and experience these ingenious agricultural systems reflect the evolution of humankind,the diversity of its knowledge and its profound relationship with nature. These systems have resulted not only in outstanding landscapes maintenance and adaptation of globally significant agricultural biodiversity indigenous knowledge systems and resilient ecosystems,but above all, in the sustained provision of multiple goods and services,food and livelihood security and quality of life. However,many of these systems are facing severe threats from various sources including globalization. In 2002 FAO initiated an international partnership initiative:“conservation and adaptive management of Globally Important Agricultural Heritage Systems(GIAHS)”.The global GIAHS initiative aims to establish the basis for the international recognition,dynamic conservation and sustainable management of such systems,agricultural biodiversity and their associated biodiversity knowledge systems,food and livelihood security,landscapes and cultures.

    The Categories and Benefit-sharing of Traditional Knowledge Associated with Biodiversity
    XUE Dayuan
    Journal of Resources and Ecology    2011, 2 (1): 29-33.   DOI: 10.3969/j.issn.1674-764x.2011.01.005
    Abstract407)      PDF (642KB)(67)      
    A milestone in the Year of Biodiversity is that the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity(CBD)was adopted in the 10th Conference of Parties(COP 10)held in Nagoya,Japan,Oct 18- 29,2010.Traditional knowledge(TK)is a key issue in the Protocol’s text and its negotiating period.This paper aimed to protect TK by defining its concepts and categories and promoting benefit-sharing with TK’s holders.Based on the analysis for the TK concepts of relevant international organizations and conventions, in particularly on the author’s current years’research work on TK in the ethnic areas of China,this paper proposes the categories and the classification system for the TK associated with biological resources,i.e. (i)the knowledge for traditional use of agricultural bio-species and genetic resources;(ii)the knowledge for traditional use of medicinal bio-species;(iii)traditional technical innovations for bio-resource use and traditional practices for farming and living styles;(iv)traditional cultures such as customary laws and community protocols that are related to conservation and sustainable use of bio-resources;and(v) traditional geographically biological indicators.Furthermore,this paper introduced the provisions for access and benefit-sharing of TK and proposed to share fairly and equitably the benefits produced from use of TK with indigenous people,local communities and other kinds of holders such as a country for the ancient documented TK.In addition,aimed to the existing problems for traditional knowledge protection,the national strategy for TK protection was introduced and measures for TK inheritance,development,utilization and protection measures were put forward,which are significant for TK’s popularization and beneficial to local communities of the ethnic groups in China.

    The Value of the Miao People’s Traditional Ecological Knowledgef or a Solution to Rocky Desertification in Mashan
    LUO Kanglong, SHAO Kan
    Journal of Resources and Ecology    2011, 2 (1): 34-45.   DOI: 10.3969/j.issn.1674-764x.2011.01.006
    Abstract199)      PDF (776KB)(80)      
    There are many branches of the Miao people in China,one of which is the Mashan Miao,who have been living in karst mountainous areas in southwest Guizhou Province.The Mashan Miao have adopted various measures for the conservation and effective utilization of the local ecological system and have made great achievements in this area.From the 1950s,their social environment has changed a lot due to political and economic movements.The rocky desertification in the Mashan area has gradually expanded. After the 1990s,relief work was carried out to address the desertification problem,but it was not very effective.We have been doing fieldwork in this area for more than 20 years and from our fieldwork records,we have found that the local Miao people have traditional ecological knowledge and skills that are of irreplaceable valuable for finding a solution for rocky desertification.Using the Miao knowledge we think a feasible way to control this disaster can be found.

    The Emergy-based Ecological Footprint(EEF)of Traditional Agricultural Areas in China:A Case Study of Congjiang County, Guizhou Province
    JIAO Wenjun, MIN Qingwen, CHENG Shengkui, ZHANG Dan, SUN Yehong
    Journal of Resources and Ecology    2011, 2 (1): 56-65.   DOI: 10.3969/j.issn.1674-764x.2011.01.009
    Abstract324)      PDF (775KB)(117)      
    Traditional agricultural systems are under severe threat from modernization,technological and economic changes,while substitution of traditional agriculture with so-called modern agriculture has caused serious non-point source pollution.Ecological footprint,though an approach to measure ecological sustainability,fails to reveal the true environmental condition of the traditional agricultural areas.This paper attempted to establish an enhanced emergy-based ecological footprint(EEF)which could include all the flows of ecosystem services that the local inhabitants had consumed,thus making EEF a better indicator of the regional sustainability.This new approach was then applied to evaluate the sustainability of Congjiang County in Guizhou Province,a typically traditional agricultural area in China.Results showed that the local biocapacity could only meet 64%of the total consumption needed by the local inhabitants,leaving an ecological deficit of 5.2327 gha per capita.This analysis was contrary to earlier findings obtained through the conventional method that Congjiang County was characterized by a small ecological reserve. Disaggregated analysis revealed that the consumption of waste treatment and erosion control services occupied a considerable proportion of the local ecological footprint,indicating that regional sustainability was under serious threat from waste discharge and soil erosion.
