Investing in fertilizer–mining companies in times of food scarcity

The primary goal of the paper is to show the validity of investing capital in fertilizer–mining companies, both from a market return perspective for individual or institutional investors, or from a hedging standpoint for insurance companies and other economic actors exposed to inflation risk and high agricultural commodity prices. After providing some elements on the fertilizer market and describing the joint dynamics of corn, wheat and fertilizer prices over the last decade, we analyze an exhaustive sample of listed fertilizer producing companies over the years January 2004–December 2012. We show that their shares generated quite good returns over the whole period and extremely high ones during the years January 2004–December 2007, both in absolute terms and compared to their betas. We also exhibit that these returns display higher sensitivities to major agricultural indexes than to the World Bank Fertilizer Index, making the hedging argument quite compelling.     

Changes in Upland Wildlife Habitat on Farmland in Illinois 1920–1987

/ An index of upland wildlife habitat was developed to investigate patterns and changes in habitat over time, using four years (1920, 1940, 1964, 1987) and the state of Illinois as an example. The index was composed of two subdivisions that described, at the county level, the quantity of wildlife habitat and a third subdivision that described farming disturbances that impacted the quality of the habitat. Data came from the US Census of Agriculture. The first subdivision that reflected quantity of habitat was called the wildlife habitat subdivision and was the sum of percentage woodland on farms, percentage farmland in nonrow crops, and percentage farmland in set-aside programs. The second subdivision that reflected the quantity of habitat was termed the soil-related features subdivision and was the sum of the percentage of farmland that was not highly erodible, the percentage of farmland in soil-protecting crops, and the percentage of farmland in conservation tillage. The third subdivision, reflecting the quality of the habitat, was the farming disturbance subdivision and was the sum of the percentage of grazing and the percentage of land on which fertilizers, pesticides, and herbicides were applied. Overall, major decreases occurred between 1920 and 1987 in the subdivisions reflecting the quantity of wildlife habitat and a major increase occurred in the subdivision associated with farming disturbance, reflecting the intensification of agriculture in the state. However, there was variability throughout the state, with some counties being more favorable to wildlife (as measured by the subdivisions) than others. Most of the changes within the state for the subdivisions reflecting quantity of upland wildlife habitat occurred during 1940 while changes in the farming disturbance subdivision (reflecting habitat quality) occurred in 1964. By 1987, the western and southern parts of Illinois were the most favorable for wildlife as reflected in all three subdivisions. Upland wildlife harvest indices were related to the subdivisions in 1964 and 1987, when harvest indices were available. Cottontail and northern bobwhite harvests were higher in counties with higher amounts of the wildlife habitat subdivision in both years. Cottontail harvest was also higher in counties with lower levels of the farming disturbance subdivision in 1964 and higher levels of soil-related features subdivision in 1987. Indices at the county level have the potential to be used in a multiscale analysis to investigate the impact of policy changes on large-scale areas of the Midwest and to develop regional perspectives of the impacts of agriculture on upland wildlife and their habitats.KEY WORDS: Upland wildlife; Habitat; Agriculture; Illinois     

Justice in development? An analysis of water interventions in the rural South

This paper explores a fruitful convergence between the distributive and procedural dimensions of environmental justice theory and current debates in the field of development studies over capitals and capabilities, institutions, and discourse formation to shed new light on natural resource management projects in the developing world. Specifically, we document the planning and implementation of two types of water interventions in two contrasting regions: watershed development programmes in northeast India and small reservoirs in sub‐Saharan West Africa. We find that there is a contradiction between the inherently political nature of water interventions and the fact that such projects remain grounded in apolitical, technical and managerial narratives. In contrast to the new semantic of development, this depoliticization results in the near absence of attention paid to procedural (participation and empowerment) and distributive (equity) justice concerns and in local actors having to revert to covert ways to achieve their ends. A constructive dialogue between development studies and environmental justice scholars can offer a fresh look on the society‐environment nexus in the developing world.     

Clove as antioxidant additive in diesel–biodiesel fuel blends in diesel engines

Increased NOx emission from usage of biodiesel is a burning issue to be dealt with. Many techniques have been adopted to reduce NOx emissions from diesel engines. The present experimental study deals with the analysis of performance and emission characteristics of Cotton Seed oil biodiesel with the addition of natural antioxidant extract of clove. FTIR analysis characterized the antioxidant by the presence of hydroxyl groups denoted by the corresponding wave number. The oxidation stability of the test samples was determined in terms of induction period by means of Rancimat test. The induction periods of the test fuel samples B100, B20, B20+CL1000, and B20+CL2000 were found to be 2.20 h, 2.73 h, 10.19 h, and 11.12 h, respectively. Thus, the addition of Clove antioxidant increased the oxidation stability of the biodiesel. Results show that the addition of antioxidant to biodiesel blend has increased the Brake Thermal Efficiency to a maximum of 4.71% and decreased the Brake Specific Fuel Consumption to a maximum of 6.25% at full-load conditions compared to Cotton Seed biodiesel blend. The addition of Clove extract antioxidant at a concentration of 1000 ppm and 2000 ppm decreases the NOx emission by 23.03% and 26.7%, respectively, at full-load conditions. However, CO emissions increased by 1.12% and 4.49% with the addition of CL1000 and CL2000 to B20, respectively. Similarly, HC emissions increased by 4.19% and 7.35% by the addition of CL1000 and CL2000 to B20, respectively. The increases in smoke with the addition of CL1000 and CL2000 to B20 were 42.48% and 47.71%, respectively.     

Private–public partnership: An exceptional solution in nature conservation in Norway

Abstract

In Norway, traditional nature conservation by government declaration is still the dominant way of protecting nature areas of national and international interest. This article presents some results from a case study of one exceptional case of private–public partnership in nature conservation. Strong opposition among local actors resulted in conservation by legal contracts between public and private actors. Discussing some possible explanations, the authors argue that a rather special network among the local community and central government and a rather creative combination of environmental and agricultural policy instruments were essential for this particular outcome.     

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.     

Who’s in Charge: Role Clarity in a Midwestern Watershed Group

Studies of collaborative watershed groups show that effective leadership is an important factor for success. This research uses data from in-depth interviews and meeting observation to qualitatively examine leadership in a Midwestern collaborative watershed group operating with government funding. One major finding was a lack of role definition for volunteer steering-committee members. Lack of role clarity and decision-making processes led to confusion regarding project management authority among the group, paid project staff members, and agency personnel. Given the important role of government grants for funding projects to protect water quality, this study offers insight into leadership issues that groups with Clean Water Act Section 319 (h) funds may face and suggestions on how to resolve them.     

Citizens’ perceptions of trust relationships in the environmental management process in North Lebanon

This research investigates how trust plays a role in environmental management in North Lebanon, which has suffered repeated episodes of armed conflict in recent times. Previous studies have shown that environmental problems have increased and that the government has been unable to address these, even during periods of relative peace. We examined trust as a factor that contributes to, or hampers, environmental management. Our analysis drew on a survey in 2011 involving 499 citizens. The results demonstrated that, according to citizens, the lack of trust between citizens, and between citizens and the public sector, is a key factor obstructing effective environmental management. The results indicate the level of correlation between how trusting people are; how citizens participate; and how people perceive government legitimacy.     

“Community in Bloom”: local participation of community gardens in urban Singapore

Community gardens offer a space that allows facilitation of leisure activities, encourages interaction within different factions in a community and helps forge a sense of belonging towards the overall community. Using the case study of “Community in Bloom” (CIB) programme initiated by the National Parks Board of Singapore, this article highlights how such community gardens are also viewed by some as exclusionary spaces due to their close links with government apparatus. More broadly, it argues that a constrained civic activism not only affects the extent to which these gardens can forge communal bonds, but they also challenge their integral spirit. Despite promising signs of politically opening up in the early 2000s, the soft authoritarianism of the Singaporean state continues to be wary of non-governmental sanctioned community projects and civic activism. This attitude may prove to be resilient in the foreseeable future, thereby preventing the “CIB” programme from truly blossoming.     

Transportation energy in global cities: sustainable transportation comes in from the cold?

The energy, environmental and social benefits of sustainable transportation, i.e. public transit, biking and walking, have long been recognized but are now mainstream in global and local transportation policy debates. However, the economic value of sustainable transportation has always been seen as secondary, unless many external costs were included. The results of a new global study show that cities with significant sustainable transportation systems have reduced costs on road construction and maintenance; better operating cost recovery and fuel-efficiency; fewer road accidents and less air pollution. In overall terms, the percentage of city funds going to transportation is reduced. The data show that cities with the most roads have the highest transportation costs and the most rail-oriented cities have the lowest. Further, the most sprawling cities have the highest direct and indirect costs for transportation. Thus, strategies to contain sprawl, to reurbanize, to build new rail systems into car-dependent suburbs with focussed sub-centers, and to facilitate biking and walking, not only will improve energy efficiency but will reduce costs to the economy of a city. Strategies that build freeways and add to sprawl will do the opposite. Trends indicate that moves toward sustainable urban patterns are beginning. The need to operationalize sustainable transportation strategies in planning and engineering practice and in the politics of infrastructure funding remains a major challenge. Some cities are showing how this can be done.     

Who participates in conservation initiatives? Case studies in six rural communities of Mexico

Previous studies attempting to explain the factors that determine local participation in conservation initiatives have concluded that socio-political exclusion is the main barrier to being involved in such initiatives. Such studies have not differentiated between different types of conservation initiatives. In this paper, we contribute to the literature analyzing the socio-cultural correlates of participation, by differentiating between participation in three types of conservation schemes: protected areas, payment for environmental services, and community conservation. We use data obtained from six rural communities in Mexico, where different combinations of conservation schemes are found. Through linear regression analysis, we explore the relationship between participation and (1) the community of residence; (2) demographics; and (3) socioeconomic characteristics of individuals. Our results suggest that local participation in conservation strategies depends, to a large extent, on the socio-political context in which they are embedded and that the exclusion of women and young adults is clearly consistent.     

Feedbacks in Human–Landscape Systems

This article identifies key questions and challenges for geomorphologists in investigating coupled feedbacks in human–landscape systems. While feedbacks occur in the absence of human influences, they are also altered by human activity. Feedbacks are a key element to understanding human-influenced geomorphic systems in ways that extend our traditional approach of considering humans as unidirectional drivers of change. Feedbacks have been increasingly identified in Earth-environmental systems, with studies of coupled human–natural systems emphasizing ecological phenomena in producing emerging concepts for social–ecological systems. Enormous gaps or uncertainties in knowledge remain with respect to understanding impact-feedback loops within geomorphic systems with significant human alterations, where the impacted geomorphic systems in turn affect humans. Geomorphology should play an important role in public policy by identifying the many diffuse and subtle feedbacks of both local- and global-scale processes. This role is urgent, while time may still be available to mitigate the impacts that limit the sustainability of human societies. Challenges for geomorphology include identification of the often weak feedbacks that occur over varied time and space scales ranging from geologic time to single isolated events and very short time periods, the lack of available data linking impact with response, the identification of multiple thresholds that trigger feedback mechanisms, the varied tools and metrics needed to represent both physical and human processes, and the need to collaborate with social scientists with expertise in the human causes of geomorphic change, as well as the human responses to such change.     

“Coal is in our food,coal is in our blood”: everyday environmental injustices of rural community gardening in Central Appalachia

ABSTRACT

Central Appalachia's historical dependence on natural resource extraction industries has contributed to a long history of under- and uneven development, including trends of persistent poverty, cycles of unemployment, weakened local governance, environmental degradation, and severe social inequalities relative to the rest of the nation. Though these trends have been well documented at structural and community-levels, scholarship is more limited in assessing how the conditions of natural resource dependency may shape the everyday experiences of those who live in such regions and how those everyday experiences may illuminate challenges for future development. Employing an embedded case study design, this study examines how everyday environmental injustices may be experienced via community gardening activities, a sustainable development-oriented activity celebrated in urban locations but largely unexplored in rural environments. Drawing upon in-depth interviews with 43 gardening programme coordinators and participants, the findings demonstrate that everyday environmental injustices are experienced across four distinct, yet overlapping and mutually reinforcing, dimensions: natural, built, human health, and socioeconomic environments. These factors in turn constrain programme participation and beneficial programme outcomes, particularly for more disadvantaged households that are affected by chronic illness, geographic isolation, and environmental hazards. Although the interviewees viewed many of these challenges as further justification for pursuing grassroots initiatives like community gardening programmes, these constraints also interacted in a way that limited the success of these locally-oriented sustainable development efforts, particularly for individuals who are the most socially, economically, and environmentally marginalised.     

Networks and spatial segregation in the production of urban poverty in São Paulo

This article discusses the importance of social networks as survival strategies, testing the impact of segregation on the structure and organisation of personal networks of low-income individuals. It presents preliminary results of an ongoing study on personal networks of individuals living in situations of poverty in São Paulo. We analyse the characteristics of 89 personal networks of poor individuals living in three urban locations, characterised by different social contents and different contexts of segregation. The results indicate a considerable heterogeneity of networks (in terms of size, diversity of sociability spheres, among other dimensions) and a strong localism, which is commonly found in the three different urban contexts. At the same time, the analysis suggests a low impact of segregation and a more complex relationship between networks and space than previously described by the international literature.     

Political Modernization in China's Forest Governance? Payment Schemes for Forest Ecological Services in Liaoning

Payment for environmental services (PES) schemes are increasingly being introduced in developed and developing countries for the ecological conservation of forests also. Such payment schemes resemble a new mode of forest governance labelled political modernization, in which centralized and state-based command-and-control policies make room for market dynamics, non-state actors, and decentralization. In entering the new Millennium, China has massively started using payment schemes to conserve its forests. An analysis of the implementation of the Forest Ecological Benefit Compensation Fund Programme in Liaoning Province is used to investigate whether China's PES schemes resemble notions of political modernization. It is concluded that Liaoning Province introduced market dynamics and farmer participation in the implementation of its PES scheme, but in a way different from that theorized by political modernization scholars. Hence, it should rather be seen as a ‘Chinese style’ political modernization process.     

Empowering communities – the role of intermediary organisations in community renewable energy projects in Indonesia

Community Renewable Energy (CRE) has been defying conventional energy systems for decades, though only recently it started to feature in academic and institutional discourses. Despite its new appeal, the literature on the impacts and factors influencing CRE projects is still scarce and builds mostly on studies in Europe and North America. In developing countries, where electricity access is low and energy poverty is prevalent, CRE can offer interesting opportunities for rural electrification and added benefits. The objective of this study is to assess the impacts of community-owned renewable energy projects and identify the internal and external drivers and barriers to their success. An exploratory case-study approach was used for collecting data, through interviews and observations, in two community micro-hydro projects in Indonesia. The results showed positive socio-economic impacts that exceed electrification benefits, and the reported success of community energy projects can be traced back to a combination of community-level as well as external factors. Yet, particularly important is the role of the intermediary organisation (Ibeka) in building communities’ ownership, enhancing (technical, entrepreneurial and managerial) capacities, transferring knowledge and technology, establishing innovative financing models and shaping policy. Such organisations are critical in bridging external and internal factors and thus represent a key element in integrating the proposed analytical frameworks.     

The misleading of public participation in environmental assessment – exploring four infrastructure cases in Denmark

The article analyses the recent development of public participation in environmental assessment and indicates some unfortunate and unintended results. A number of Danish cases show how the tools involved are employed for a kind of ‘acceptance planning’, instead of actual environmental protection, and that the legitimacy which public inclusion was supposed to bring to environmental assessment has instead been replaced by considerations of legality, which frees entrepreneurs and authorities from including real environmental considerations in their planning. Thus, the undesirable handling of public participation that the article analyses is not only due to the actual difficulties of practising inclusion and the indisputable complexity of the environmental issues but also to a very large extent due to considerations of economic efficiency and an unwillingness among investors – public as well as private – to take account of environmental consequences as a long-term issue. The article ends with a range of recommendations for securing public inclusion in matters of environmental assessment through independent public initiatives or institutions that do not answer to authorities and entrepreneurs.     

Perceived landscape values and public participation in a road-planning process – a case study in Sweden

The European Landscape Convention indicates that assessment of different dimensions that exist in landscapes should be taken into account in planning. In this study, we first investigated ecological, cultural and social values as perceived by the local people in a highway-planning process in Sweden. Next, we explored which factors influenced the local people's participation in the road-planning process. We used questionnaires, planning documents and the Theory of Planned Behavior to investigate the relations between different factors and local people's participation in the planning process. The results showed that people presumed the ecological values in the landscape to be adversely affected by the new road, while the social values would remain the same. Landowners had heard of the participatory-process, but few participated. Those who lived within 300 m of the road were more active in the planning process than people living further away. The findings suggest that people living within a few hundred metres of the road should be treated as key stakeholders in the planning process. The involvement of other stakeholders, and when in the public participation process stakeholders should be involved, is also discussed.     

What is in a name? Language,framing and environmental justice activism in California's Central Valley

According to the environmental justice (EJ) literature, one important factor in the movement's success is the development of a frame linking inequality to the disproportionate presence of environmental toxins in low-income communities of colour. This article highlights the resonance of this frame among grassroots activists and professional advocates in California's Central Valley. However, through interviews and focus groups with activists and advocates in six Central Valley communities, we found that only the latter identified their work as EJ. Grassroots activists instead identified their work as about health, community development and environmentalism. Moreover, some were unfamiliar with EJ as a concept while others denied its applicability to their work. Theoretically, our findings suggest that frame resonance needs to be delinked conceptually from movement identification; it is possible for a movement's analysis of social problems and solutions to resonate among those who do not identify with the movement itself. Pragmatically speaking, this can prevent some grassroots activists who are directly affected by environmental racism from accessing the resources and networks that the EJ movement has painstakingly built, and suggests that movement leaders may need to increase their outreach to community groups.     

Policy Interactions in Human–Landscape Systems

Given the heightened pace and extent of human interactions with landscapes, there is increasing recognition of the interdependence of hydrogeomorphological, ecological, and human systems in understanding human–landscape interactions. There is also widespread agreement for greater integration across disciplinary boundaries to generate new knowledge urgently needed for theory building to understand, predict, and respond to rapidly changing human–landscape systems. The development of new conceptual frameworks, methods, tools, and collaborations linking across the natural and social sciences are key elements to such integration. In an effort to contribute to a broader conceptual framework for human–landscape systems, this paper describes how environmental policy research has contributed to four integrative themes—thresholds and tipping points; spatial scales and boundaries; feedback loops; and time scales and lags—developed by participants in an NSF-sponsored interdisciplinary workshop. As a broad and heterogeneous body of literature, environmental policy research reflects a diversity of methodological and theoretical approaches around institutions, actors, processes, and ideas. We integrate across multiple subfields and research programs to help identify complementarities in research that may support future interdisciplinary collaborative work. We conclude with a discussion of future research questions to help advance greater interdisciplinary research around human–landscape systems.
