Food production in the city: (re)negotiating land,food and property

This paper addresses issues of access to land for food production in Toronto by offering fresh perspectives on urban agriculture in the neo-liberal city of the global north. It examines attempts to scale up urban agriculture that emphasise changing the relationships between land access, property and new collaborative relationships among different stakeholders. These initiatives involve renegotiating access to land for growing food between private property owners and landless growers, concomitant shifts in control over valued resources and commercialisation. These shifts are often based on relations of trust within a sharing economy rather than public battles over political decisions to develop urban agriculture lands. Growing food on private lands in the city is political in challenging taken-for-granted ideas and practices of property and urban agriculture. New approaches offer options for training and income, as well as expanding the land base for urban agriculture. Small-scale farming projects are affirmative political manoeuvres. They challenge urban residents to consider land for food production across the categories of public and private property. We document three approaches that challenge current property relations: temporary use of a development site through “soft” squatting; redesignating suburban backyards for farmer training and community-based and private food production; and garden sharing of private home backyards for urban food production and commercial growing. Such initiatives articulate alternative visions of sustainability and food security that rely on principles of collaboration and a sharing economy that challenge prevailing notions of property ownership and food security.     

Sri Lankan livelihoods after the tsunami: searching for entrepreneurs,unveiling relations of power

This paper analyses the performance of aid‐funded livelihoods recovery efforts in Sri Lanka following the Indian Ocean tsunami of 26 December 2004, with special attention paid to the effects on the rural poor. It argues that successful livelihoods recovery was hampered by an excessive focus by aid agencies on entrepreneurs and entrepreneurship, and by the lack of a politically informed understanding of the economy. Based on ethnographic and survey‐based research, the study demonstrates that the category of ‘entrepreneur’ is misleading for large parts of the economy. Indeed, the desire to build an entrepreneurial economy actually hampered successful livelihoods recovery in Sri Lanka and, in some cases, reinforced inequitable relations of power. The paper concludes that for livelihoods recovery programmes to be effective, they must be founded on an understanding of the relations of power that constitute the economy; these relations operate across scales, and are historically and geographically specific.

African voters indicate lack of support for climate change policies

Will African voters support climate change policies? By 2020, the United Nations’ Green Climate Fund intends to provide tens of billions of dollars per year to African nations to support climate adaptation and mitigation policies. It is widely assumed that African citizens will support implementation of these climate policies. We observe the opposite result. In this article – across two experimental studies – we find evidence that Sub-Saharan African politicians who commit to climate change policies may lose electoral support. Electorally important swing voters with weak party affiliations are least likely to support party statements about climate change. Interviews with standing elected officials from Malawi and South Africa corroborate our experimental findings. The combined results suggest voter preferences may hinder the successful implementation of climate change policy in Sub-Saharan African democracies.     

Contesting neoliberal knowledge politics in restoration governance: the restorationist’s dilemma

ABSTRACT

The success of ecological restoration efforts is tightly coupled with the effectiveness of many U.S. environmental policies. Yet scholars have raised questions about the ability of restoration to produce intended results. We use a case study of tidal wetland restoration planning in Oregon to examine how neoliberal environmental governance exercises influence through a set of knowledge politics that produces subpar outcomes. We present three main findings: (1) restoration policies produce a restoration economy based on a conception of wetland as commodity (2) practitioners in this restoration economy exhibit competitive behavior resulting in a piecemeal rather than a landscape approach to restoration; and (3) limited monitoring prevents changes to existing policies. Practitioners offer insight into the challenge of treating wetlands as a commodity and call for more monitoring to challenge the assumptions of hegemonic knowledge practices that reinforce a neoliberal environmental governance regime. The divergent ideas of reflexive practitioners, though not yet manifest as action, show where changes to restoration governance might be possible.     

WATER RESOURCE POLITICS AND INTEREST GROUP TACTICS1

ABSTRACT: The traditional strong role of interest groups in water resources policy making has been modified recently by the introduction of many environmental groups. The new groups differ from traditional groups in their relatively modest resources and their relative lack of access to traditional decision points. This paper examines the extent to which the new groups differ in their perceptions of the effectiveness of tactics and in their use of tactics, taking into account group resources and group access to decision makers.     

国际环境制度对能源安全战略的重大影响

能源安全一直是国际政治和经济领域的重大问题。在追求可持续发展和全球化不断推进的2l世纪,国际环境制度的逐步形成为能源安全赋予了新的涵义,生态安全已经成为能源安全的重要组成部分。以保障能源供应为主要出发点的传统能源安全观逐渐向着涵盖能源供应、经济竞争力和环境质量三大要素的“综合能源安全观”的方向发展。

Proliferating Principles; Or How to Sup with the Devil without Getting Eaten

The international humanitarian system is seen by many to be in crisis. The reasons for this are complex but include the perception held by many that there is an increasing ambivalence on the part of powerful states to invest military, political and financial resources in upholding humanitarian principles, and a growing feeling that much humanitarian action both ignores human rights issues and can prolong conflict. As a result, much attention has focused on the notion of 'humanitarian principles' and there has been a proliferation of statements and initiatives on this topic in recent years.     

Establishing the link between ammonia emission control and measurements of reduced nitrogen concentrations and deposition

In the context of international efforts to reduce the impactsof atmospheric NH₃ and NH₄ ⁺ (collectively, NH_x), it is important to establish the link between NH₃emissions and monitoring of NH_x concentrations and deposition. This is equally relevant to situations where NH₃emissions changes are certain (e.g. due to changed source sectoractivity), as to cases where NH₃ abatement technologies havebeen implemented. Correct interpretation of adequate atmosphericmeasurements is essential, since monitoring data provide the onlymeans to evaluate trends in regional NH₃ emissions.These issues have been reviewed using available measurements and modelling from nine countries. In addition to historic datasets,the analysis here considers countries where NH₃ source sector activity changed (both increases and decreases) and countries where NH₃ abatement policies have been implemented.In The Netherlands an `ammonia gap' was identified between the expected reduction and results of monitoring, and was attributedinitially to ineffectiveness of the abatement measures. The analysis here for a range of countries shows that atmospheric interactions complicate the expected changes, particularly sinceSO₂ emissions have decreased at the same time, while at manysites the few years of available data show substantial inter-annual variation. It is concluded that networks need to beestablished that speciate between NH₃ and aerosol NH₄ ⁺, in addition to providing wet deposition, and sample at sufficient sites for robust regional estimates to be established. Such measurements will be essential to monitor compliance of the international agreements on NH₃ emission abatement.
