我国可持续发展中的绿色技术体系

本文在剖析绿色技术的概念内涵与特征的基础上,构建了由清洁生产技术、资源化技术、末端治理技术、生态农业技术、绿色食品技术、清洁消费技术与生态恢复技术等为主要内容的我国绿色技术体系,并从行政、经济、法律、教育及科研等五个方面阐述了促进我国可持续发展的绿色技术实施策略。     

生态农业建设中的政府行为探讨

建设生态农业是农业进一步发展的必然选择。生态农业生产中的系统性、协调性以及可持续性等特征，决定了发展生态农业离不开政府的调控与支持。此外，解决外部性问题以及提供建设所需的公共品，也是政府的主要职责。然而，当前政府在扶持生态农业建设中还存在着制度体系建设不完善、资金扶持力度不足等状况，限制了生态农业的持续快速发展。为此，应当通过培养生态农业意识、完善制度体系、推进生态农业产业化以及开发相应的科学技术等途径，来推进生态农业的建设步伐。

通过对生态农业内涵与模式的认识，指出中国生态农业的研究侧重于对生态脆弱区与具体模式的提炼，而对经济发达区、城郊区缺乏研究，对社会经济条件关注较少。针对芜湖市自然条件、社会经济条件和生态环境现状等地域基础的分析，分别从产品、产业、地域三个方面进行了生态农业系统设计，从而力图把握生态农业的系统本质，将生态建设、经济建设以及各种支撑体系建设进行综合考虑，充分发挥生态农业思想在区域发展中的作用。     

Embarking on the Second Green Revolution for Sustainable Agriculture in India: A Judicious Mix of Traditional Wisdom and Modern Knowledge in Ecological Farming

The Green Revolution in India which was heralded in the 1960‘s was a mixed blessing. Ambitious use of agro-chemicals boosted food production but also destroyed the agricultural ecosystem. Of late Indian farmers and agricultural scientists have realized this and are anxious to find alternatives – perhaps a non-chemical agriculture – and have even revived their age-old traditional techniques of natural farming. Scientists are working to find economically cheaper and ecologically safer alternatives to agro-chemicals. Blue-Green Algae Biofertilizers, Earthworm Vermicomposts (Vermiculture), biological control of pests and herbal biopesticides are showing promise. Saline agriculture and sewage farming are also being promoted in India to augment food production in the face of water scarcity. There is a move to search for alternative foods, which are more nutritious, cheaper and have shorter harvest cycles. Farm and food policy in India has to change its outlook before there can be a second green revolution. This revised version was published online in August 2006 with corrections to the Cover Date.     

Gathering “wild” food in the city: rethinking the role of foraging in urban ecosystem planning and management

Recent “green” planning initiatives envision food production, including urban agriculture and livestock production, as desirable elements of sustainable cities. We use an integrated urban political ecology and human–plant geographies framework to explore how foraging for “wild” foods in cities, a subversive practice that challenges prevailing views about the roles of humans in urban green spaces, has potential to also support sustainability goals. Drawing on research from Baltimore, New York City, Philadelphia, and Seattle, we show that foraging is a vibrant and ongoing practice among diverse urban residents in the USA. At the same time, as reflected in regulations, planning practices, and attitudes of conservation practitioners, it is conceptualised as out of place in urban landscapes and an activity to be discouraged. We discuss how paying attention to urban foraging spaces and practices can strengthen green space planning and summarise opportunities for and challenges associated with including foragers and their concerns.

Facilitating (?) urban agriculture in Philadelphia: sustainability narratives in the inequitable city

In 2008, the city of Philadelphia made increasing healthy food access a priority for sustainable development. Recognising that almost 25% of the population are considered food insecure, government agencies, non-governmental organisations and community leaders sought to increase food access through increasing food production and access to land in the city. Urban agriculture has gradually been incorporated in sustainability narratives in the past decade, both providing a platform for advocates to inform on policymaking, and potentially stripping away the political and activist origins of gaining access to food, land and green spaces in the city. In this paper, we argue that the depoliticising of urban agriculture advocacy through its incorporation in sustainability planning may serve to increase existing inequities in the city. Focusing on the policy-making scale, we examine measures enacted under the Philadelphia Greenworks Sustainability Plan to facilitate urban agriculture in the city. Our preliminary findings suggest that the processes by which urban agriculture gains acceptance demonstrate a disconnect in urban agriculture advocacy and policymaking and further work is needed to understand the impacts of the formalising of urban agriculture in Philadelphia.

Seeking Indigenous food sovereignty: origins of and responses to the food crisis in northern Manitoba,Canada

A food crisis confronts many Indigenous communities in northwestern Canada, as reflected by wide-scale food insecurity and diet-related disease. South-generated responses to this crisis generally disregard principles of Indigenous food sovereignty and are disengaged from concerns related to environmental and food justice. This study seeks to explore the needs and priorities of a First Nation (Misipawistik Cree Nation) and an associated Métis community (Grand Rapids) regarding existing and potential responses to the food crisis in northern Manitoba. Substantial changes to the traditional food system were initiated during the establishment of the reserve system in the 1800s and now extend to damage associated with hydro development. Responses to these changes were categorised according to themes and include the revival of country food traditions, individual and community gardens, agriculture in the North, and better quality imported foods. Regardless of response, decision-making needs to be community-driven, culturally appropriate, to reflect local priorities in order to effectively address the northern food crisis, and, ultimately, needs to work towards Indigenous food sovereignty to be effective.
