The EU vision of sustainable agriculture, land use, forestry and management of natural resources contributes to the balanced exploitation of the environment, taking into account rural development strategy. Whilst the EU directs activities through legislative tools, national systems of public administration are responsible for the implementation of the respective laws. Despite there not being acquis communautaire in public administration, non-formal cooperation has nevertheless emerged and systems of national public administration have to meet EU criteria and ensure the effective implementation of legislation. The paper presents an analysis of how Slovak state administration has converged with EU requirements in the field of sustainable agriculture, land use, forestry and natural resources. Administrative convergence is considered through the internal convergence represented by capacities without legal subjectivity, and through external convergence represented by legal and administrative subjectivity. Both approaches are observed at the central level within specialized public authorities. Local state administration is characterized by the creation of internal administrative capacities with the challenging delimitation of which competences are affected by the process of administrative convergence.  相似文献

Healthy, fertile soil is the material of life itself. It is chemically, biologically and physically structured to support the growth of healthy, environmentally sustainable foods. Recent years have seen a resurgent focus on soil science in Australia. Yet, the influence of soil in the politics of food systems has received comparatively little attention, despite long awareness in farming communities of how the natural world shapes farmers’ choices and possible actions. Drawing on work with SoilCare, a Landcare group with a focus on soil processes in the Northern Rivers of New South Wales, this paper explores the usefulness of approaching soil as an actor in food systems. Taking a participatory approach, and drawing on recent work on new materialisms, we argue that soil can be understood as an important ally in the struggle to shape a just and sustainable food system. While this work is intended to test this idea through a modest local case study, it may point to important new avenues for investigation in food politics.  相似文献

A key characteristic of global organic agriculture governance through standards is the coexistence of regulatory fragmentation and regional integration. To reduce barriers to organic trade, especially for market participants from developing countries, international and transnational entrepreneurs increasingly promote the setting of organic agriculture standards (OAS) in different world regions, for example, in East Africa, the Pacific, or Asia. Although scholars from different disciplines have done a lot of research on the role of standards in global governance, we still know little about why and how regional standard-setting processes evolve. Applying findings from regime analysis, entrepreneurship, and political authority, the article introduces the concept of authority pooling. It argues that legal, moral, and technical authority sources interact in a blurred functional division of labour between the public and the private sector in standard-setting. The article presents results from a within-case study of the development of the East African Organic Products Standard using the process-tracing method. It detects the underlying causal mechanism by which international and transnational entrepreneurs pooled different authority sources and, thus, significantly influenced political actors in East Africa to set the first regional OAS in the developing world.  相似文献

Throughout the low-income world, agricultural producers have a motivation to slash-and-burn rainforests as they cannot afford inorganic fertilizers. Farmers in the Democratic Republic of the Congo (DRC), who are predominantly women, are often forced to walk long distances to cultivate more productive lands, when fertility near their villages is reduced. On their way and while working away from home, women become targets for rape. Adopting conservation agriculture (CA) could help mitigate deforestation and potentially create a safer environment for women. Limited knowledge about the benefits of CA across countries in Sub-Saharan Africa (SSA) has hindered its adoption. Taking these impediments into account, we estimate if consumers in the DRC are willing to pay (WTP) a premium for CA, using maize flour as the medium. By means of a double-bounded dichotomous choice valuation method, 600 consumers in Bukavu, DRC, were surveyed about their willingness-to-pay for CA-produced maize. Our study finds that only those consumers who identify themselves as farmers are WTP a premium. This study indicates that if CA adoption is to spread in the DRC, it will likely need to happen via increased yields or reduced costs before the farm gate and not premiums after the farm gate.  相似文献

Addressing the global challenges of climate change (CC), food security and poverty alleviation requires enhancing the adaptive capacity and mitigation potential of land use systems. To this end, Climate Smart Agriculture (CSA) aims to identify land use practices that sustainably increase productivity, enhance climate change (CC) adaptation and contribute to CC mitigation. A transition towards CSA requires technical, but also socio-institutional changes, for improved smallholder agricultural systems. Such changes may be triggered by stakeholder participation processes that stimulate social learning and collective action. This article evaluates whether a role-playing game (RPG) is an effective participatory tool to encourage social learning and collective action among local stakeholders towards adoption of CSA strategies. We designed and implemented an RPG with three groups of farmers in Apuí (Southern Amazonas), evaluating the game’s impact on social learning by interviewing each farmer before and after the RPG. Our findings show that the RPG induced not only technical learning, but also socio-institutional learning and engagement for collective action, though outcomes varied between different RPG sessions and among farmer participants.  相似文献

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.  相似文献

Food sovereignty movements (FSMs) globally have sought to rearrange relations between land, power, state actions and societal forces outside the state, towards a new ideal of democratised, egalitarian and ecological food systems. The question of how best to reach this ideal has vexed movements and scholars alike, with many anti-capitalist theorists proposing that because of the historical dedication of states to maintaining unequal and unsustainable capitalist relations, change must be pursued outside and against the state rather than through it (i.e. through “autonomism”). Yet, analysis of FSMs globally shows that autonomism is relative, partial and best seen as an aspirational ideal rather than a fixed dogma. This paper deepens this insight by analysing a case within the United States where a local direct action group promoted food sovereignty by illegally occupying public land. The case shows how even apparently autonomist movements can through influence on state and societal actors contribute to state-based “policy currents” that flow in the direction of food sovereignty. This mutual codetermination by actors in and out of state institutions of the possibility and shape of “policy currents” renders state–society relations as important, even to those interested in (relative) autonomism. This paper thus leaves behind dichotomous interpretations of (and recommendations for) FSMs vis-à-vis autonomism, in order to unpack the influence (in thought) and impact (in action) of autonomist tendencies in food sovereignty construction.  相似文献

The Seymour aquifer consists of unconfined outcrops of sand and gravel in a semiarid, agricultural region of north‐central Texas in the United States of America. Most water samples collected from the aquifer in 2015 had nitrate concentrations above the drinking water standard of 44.3 milligrams per liter (mg/L). Generally, areas with high nitrate concentration in 2010 remained high in 2015, although the median dropped by 3.9 mg/L. The largest decreases in nitrate concentration—up to 97 mg/L (60%)—were observed in wells with depths less than the median of 13.1 meters (m). However, other wells, including depths above and below the median, showed increases in nitrate concentration of up to 40 mg/L (42%). In 2015, chloride concentrations in six wells exceeded the secondary contaminant level of 250 mg/L, and one well had a chloride concentration of 1,810 mg/L. Past and ongoing agricultural practices, including cultivation of native grassland, application of fertilizer, and irrigation with nitrate‐contaminated groundwater, help sustain overall high nitrate concentrations within the aquifer. Local conditions governing nitrogen inputs and dilution result in significant improvement or worsening of the nitrate problem over relatively short timeframes. The pumping of groundwater from the aquifer may facilitate mixing with groundwater of increased salinity that has been affected by the dissolution of evaporites in underlying Permian bedrock.  相似文献
