This paper provides an overview of what we call ‘agroecological revolution’ in Latin America. As the expansion of agroexports and biofuels continues unfolding in Latin America and warming the planet, the concepts of food sovereignty and agroecology-based agricultural production gain increasing attention. New approaches and technologies involving the application of blended agroecological science and indigenous knowledge systems are being spearheaded by a significant number of peasants, NGOs and some government and academic institutions, and they are proving to enhance food security while conserving natural resources, and empowering local, regional and national peasant organizations and movements. An assessment of various grassroots initiatives in Latin America reveals that the application of the agroecological paradigm can bring significant environmental, economic and political benefits to small farmers and rural communities as well as urban populations in the region. The trajectory of the agroecological movements in Brazil, the Andean region, Mexico, Central America and Cuba and their potential to promote broad-based and sustainable agrarian and social change is briefly presented and examined. We argue that an emerging threefold ‘agroecological revolution’, namely, epistemological, technical and social, is creating new and unexpected changes directed at restoring local self-reliance, conserving and regenerating natural resource agrobiodiversity, producing healthy foods with low inputs, and empowering peasant organizations. These changes directly challenge neoliberal modernization policies based on agribusiness and agroexports while opening new political roads for Latin American agrarian societies.  相似文献

Worldwide investments in agricultural land have gained much attention in recent years, resulting in renewed awareness of land as being a scarce and finite resource. This paper investigates a case of South-to-North land deals, namely investments from the Arab Gulf targeting agricultural land in Australia. For the Arab Gulf States that highly depend on external food supplies, investment abroad is one strategy to guarantee future food security. At the same time, leading Australian political and economic representatives have been eager to attract investments from the Gulf. Increasing foreign investment in Australian land has, however, provoked a vivid public debate in Australia. Concepts of foreign direct investment and its role are currently renegotiated on the federal level with regard to Australia's own food security, the ‘national interest’ and the redefinition of ‘Australian agricultural land’. While these concerns also play out on the local level, investments have to be seen within the wider context of Australian ruralities. The paper reveals how food security and commercial and financial interests intersect and become blurred within current transformations of the global agri-food system.  相似文献

This essay examines the competing readings of food refusal that emerged from a student hunger strike held at Columbia University in fall 2007. The invisibility of the act of food refusal forces hunger strikers to adopt performance strategies that make their (non)action visible as protest. To make the politics of their food refusal legible, advocates for the hunger strike promoted their actions as part of a 40 year tradition of student protest. However, that same invisibility allowed the protest's detractors to deride the hunger strikers as anorexic. At the center of the protest and the commentary about it was a wasting female body that confused for spectators the line between the political and the pathological. Attention to this body raises questions of how community is created and disciplined through performative acts, how easily female protest is evacuated of political meaning and the uneasy role of whiteness in popular attention to anorexia.  相似文献

This article illuminates how performances of gender, race, and sexuality are integrated with representations of food and food performance in contemporary American cooking television. Interrogating the intersections of food, gender, race, sexuality, and performance, this essay explores how the cable-television show, Down Home with the Neelys, depicts a nouveau gastro-porn anchored in the perceived pornographic level of blackness itself. The author reveals the ways that food and performances of food become a medium of gendering and racialization employed by American popular media. Through the lens of reality television, shows like Down Home (re)produce a certain type of black heterosexuality and gendered enactments of domesticity and space, while challenging dominant televisual reflections of black love and labor. The author argues that the Neelys self-consciously employ a vernacular aesthetic performative of “down home” (a uniquely classed, temporally–spatially situated, and sexualized blackness) to exploit the phenomenon of gastro-porn in a highly lucrative performance that signals the entangled artifice of gender, race, and sexuality. More than offering culinary expertise and education, such cooking instruction reveals the pedagogy of gender, race, and sexuality as visual lessons of a complex and contradictory authenticity. This essay reveals television cooking shows as critical sites for considering the domestic laboring of gendered and racialized sexualities. In particular, shows like Down Home evince the ways that race continues to be rendered in visual terms and the enduring edibility of blackness.  相似文献

粮食是人类生存和发展的基本物质条件,是关系国家安全、政治稳定与社会和谐的重要战略性资源。粮食安全化与政治化是国际政治研究的热点问题之一。鉴于此,重新发现中国春秋战国时期已形成的粮食安全思想,从粮食对国家安全、国家权力以及国家道义层次考察彼时粮食安全思想,具有重要的现实意义。“不生粟之国亡”,粮食安全是国家安全的基础;“富国以粟”,粮食是国家富强的保证;粮食关乎人心向背和国家道义。齐桓公为建立霸业实施了粮食外交与粮食战略,开创了现代粮食战争的先河。“不生粟之国亡”是中国春秋战国时期粮食安全思想的核心和根本,也是对中国古代粮食安全思想再发现的落脚点。基于此,当代中国粮食安全战略应立足于坚持独立自主原则,保障国内粮食生产,积极开展粮食外交,实行粮食“走出去”战略,在全球化背景下确保实现国家粮食安全。这不仅是保障国家安全的重中之重,也是中华民族实现“中国梦”最重要的物质基石。  相似文献
