Multifunctional intervention and market rationality in agricultural governance: a comparative study of England and South Australia

Critiques of the neoliberal governance of agricultural systems have led to a number of political responses which attempt to address the socio-environmental consequences of the dominant regime. In this paper two case study regions (South Australia and England) have been chosen to represent variations in agricultural policy and to highlight subsequent outcomes on the sustainability of agriculture. Interviewed governance stakeholders highlighted issues in regard to the agricultural governance of each area, from social and environmental consequences of minimal policy intervention in South Australia, to issues created by greater economic support in England. As such, the distinct variations in agricultural regimes will continue to demand scholarly attention, in order for the value of diversity within the sector to be more widely understood. The study concludes that it is likely agricultural support will continue to decline in both case study regions. Importantly, however, innovative policy mechanisms that aim to reduce local risks and value local agricultural priorities, without requiring significant financial support, might be the most promising way forward in regard to agricultural system sustainability.     

“This is a Montreal Issue”: Negotiating responsibility in global production and investment networks

While geographers have increasingly focused on how global commodity and production networks create new ‘geographies of responsibility’ there has been little empirical work considering how responsibility is worked into management systems and social activism in such networks. Drawing on literature from global production networks, geographies of responsibility and other literatures, this paper explores the dynamic and contested ways in which concepts of responsibility can play a role in network regulation. Both foreign direct investment and commodity networks (here referred to as ‘global production and investment networks’) are subject to complex negotiations and compromises involving corporate social responsibility and sustainability initiatives as well as shareholder activist, human rights, labor, and environmental activism. This is illustrated by reference to conflicts in Canada over Alcan, Inc.’s investments from 1993 to 2007 in the Utkal Alumina Project in Orissa, India. The project involved significant socio-environmental conflict. In Canada, Alcan’s investment was met by civil society campaigns that tested the company’s commitments to sustainability and corporate social responsibility. The case study suggests revising theories of geographies of responsibility. While foreign direct investment can create new relationships between distant others, these are fluid and contingent and not necessarily desirable. Rather than see networks as a source of responsibility we should work to ensure that the relationships that networks foster be structured to ensure our deeper values are respected.     

Late Holocene climatic history of northern Germany and Denmark: peat macrofossil investigations at Dosenmoor, Schleswig-Holstein, and Svanemose, Jutland

Plant macrofossil remains have been analysed from two raised peat bogs in northern Germany and Denmark. The quantified vegetation reconstructions of each profile were subjected to multivariate analyses to extract records of changing bog surface wetness (BSW), which are interpreted in these rain-fed bogs as being proxy climate signals. Age/depth models were constructed using radiocarbon dates and a number of drier and wetter phases were defined. The records both register cooler/wetter conditions around 2700, 1800 and 1400 cal. yr BP, and at the beginning of the Little Ice Age around AD 1250–1350. These rising bog water tables must have been reflected in poorer conditions for agriculture, and in particular near Dosenmoor where the profile records a catastrophic change to such conditions culminating at 2750–2600 cal. yr BP.     

Seismic interferometry and ambient noise tomography in the British Isles

Traditional methods of imaging the Earth's subsurface using seismic waves require an identifiable, impulsive source of seismic energy, for example an earthquake or explosive source. Naturally occurring, ambient seismic waves form an ever-present source of energy that is conventionally regarded as unusable since it is not impulsive. As such it is generally removed from seismic data and subsequent analysis. A new method known as seismic interferometry can be used to extract useful information about the Earth's subsurface from the ambient noise wavefield. Consequently, seismic interferometry is an important new tool for exploring areas which are otherwise seismically quiescent, such as the British Isles in which there are relatively few strong earthquakes. One of the possible applications of seismic interferometry is ambient noise tomography (ANT). ANT is a way of using interferometry to image subsurface seismic velocity variations using seismic (surface) waves extracted from the background ambient vibrations of the Earth. To date, ANT has been used successfully to image the Earth's crust and upper-mantle on regional and continental scales in many locations and has the power to resolve major geological features such as sedimentary basins and igneous and metamorphic cores. Here we provide a review of seismic interferometry and ANT, and show that the seismic interferometry method works well within the British Isles. We illustrate the usefulness of the method in seismically quiescent areas by presenting the first surface wave group velocity maps of the Scottish Highlands using only ambient seismic noise. These maps show low velocity anomalies in sedimentary basins such as the Moray Firth, and high velocity anomalies in igneous and metamorphic centres such as the Lewisian complex. They also suggest that the Moho shallows from south to north across Scotland which agrees with previous geophysical studies in the region.     

A Conceptual Framework for Enhancing the Utility of Rainfall Hazard Forecasts for Agriculture in Marginal Environments

Semi-arid and dry sub-humid areas (especially in the tropics) are characterized by high inter-annual and intra-seasonal rainfall variability. Agriculture, which employs the bulk of the rapidly increasing populations, is largely rain-fed, low-input based and highly resource dependent. Recent spates of drought have, therefore, exacerbated the now-too-familiar specter of famine and starvation in these areas with glaring examples being the recurring episodes in sub-Saharan Africa since the great Sahel drought of 1969–1973. A great need for accurate and timely hazard forecast products in aid of agriculture thus exists.Several schemes are currently employed by various agencies around the globe in this direction. There does remain, however, a gap between product provision and user expectations. This paper examines this gap suggesting a five-point framework within which it can be addressed as an action agenda for the climate science community. The paper posits that changes are possible to existing methodologies (related to three of these points), which, within the context of current science, can greatly enhance the utility of forecast products for agriculture in marginal areas. The remaining two points have, however, been identified as requiring additional applied research and necessary pointers for addressing these issues are provided. First is the need for appropriate impact-related indicators for intra-seasonal and interannual rainfall variability that are easy to compute, amenable to forecasting and follow closely the experiences of farmers in marginal areas. The second is a consideration of appropriate forecast information formatting and communication medium that guarantee effective feedback between forecast producers and users. Specific examples of the status quo and of work currently underway are cited from southern Africa – a region currently attracting international attention as a result of recent droughts and the threat of famine.     

Farming the urban fringes of Barcelona: Competing visions of nature and the contestation of a partial sustainability fix

While the concept of urban agriculture investigates the way in which disused land within the consolidated city is returned to its citizens through a variety of farming practices, many pockets of rural land in peri-urban areas continue to be contested by institutions and communities – including informal farmers, formal farmers, municipal planners, metropolitan agencies, and investors – with contrasting interests. To date however, little scholarly attention has been paid to informal practices within the degraded areas of urban fringes and, more specifically, to the link between the expansion of peri-urban agriculture and the civic appropriation and negotiation of space in neglected peripheral areas. In this paper, we ask how a metropolitan sustainability fix is produced and contested both materially and discursively. We also explore how local residents involved in peri-urban agriculture claim the use of land for agricultural practices and in turn attempt to influence the urban agenda of the neoliberal city. Inquiring how competing visions of nature act as obstacles in this negotiation process, our analysis of the peri-urban Baix Llobregat Agricultural Park in Barcelona reveals that the imposition of official visions about how needs for food and agriculture should be fulfilled, which landscapes are esthetically acceptable, what nature is, and how land should be controlled and developed indicate why apparently “marginal” and informal urban agriculture in the periphery has come to be subordinated to the planning of the neoliberal city and of a metropolitan sustainability fix – a partial sustainability fix that is however progressively being questioned and renegotiated.     

GMOs and their contexts: A comparison of potential and actual performance of GM crops in a local agricultural setting

In this paper, I argue that genetically modified organisms (GMOs) have inherent potential to contribute to socially and environmentally sustainable agriculture by virtue of their ‘biological embeddedness’. Their actual ‘performance’ and how this contributes to sustainability depends on the ‘mutual shaping’ of technology and context. While much attention has been given to the design context of GMOs, this paper considers the influence of the application context and of users. A case study investigating the use of insect-resistant and herbicide-tolerant GM cotton in the cotton-growing region of New South Wales in Australia is presented. The study was based on focus groups with farmers and other stakeholders in a cotton-growing community. It demonstrated a range of direct and indirect effects of GM cotton use, both positive and negative for sustainability, and the ways in which these effects were influenced by the local social context. The influences of the biotechnology industry context, in limiting the contributions that gene technologies can make to sustainability, were also considered, and remedies suggested. I argue that the polarity of the GM debate is hindering progress on these issues, and that a more balanced approach to our analysis of GMOs is necessary in order to fully understand, and to influence, their role in the future of rural spaces.     

The ‘leisuring’ of rural landscapes in Barbados: New spatialities and the implications for sustainability in small island states

The transformation of rural areas into up-scale leisure amenity landscapes has become a global phenomenon. Small islands, especially in tropical and subtropical regions, are particularly attractive magnets for this kind of development. Yet it involves land use changes that challenge the sustainability of small island development as set out in the United Nations program for Sustainable Development of Small Island Developing States (SDIDS). Through a case study of Barbados this paper critically examines the ‘leisuring’ of rural landscapes on small islands. It ties together Lefebvrian concepts of the production of space with the perspective of political ecology to argue that the agendas of global capital impose new spatialities involving social constructions of space and socio-environmental transformations by an offshore elite who are insensitive to local interests as well as the smallness of small islands. This creates conflict between space and place - between the spaces produced by the global leisure economy and the places that have purpose and meaning for local people. It challenges the possibility of local, community-based development solutions and imposes serious constraints on the implementation of the SDIDS agenda. More research into the nature of the new leisure spaces and how they are perceived and experienced by local populations is needed.     

Traditional prediction of drought under weather and climate uncertainty: analyzing the challenges and opportunities for small-scale farmers in Gaza province,southern region of Mozambique

This paper explores the traditional indicators that small-scale farmers in Gaza province in southern Mozambique use to predict drought events on their rain-fed farms. It analyzes the contextual situation regarding the accuracy and reliability of the traditional prediction methods under the current weather and conditions of climate uncertainty and variability, and the opportunities that their prediction methods can bring to reduce their current and future exposure and vulnerabilities to drought. Farmers use a total of 11 traditional environmental indicators to predict drought, either individually or combined, as required to increase their prediction certainty. However, the farmers perceive that current unpredictability, variability, and changes in weather and climate have negatively affected the interpretation, accuracy, and reliability of most of their prediction indicators, and thus their farming activities and their ability to predict and respond to drought. This, associated with the reduced number of elders in the community, is causing a decline in the diversity, and complexity of interpretation of indicators. Nonetheless, these difficulties have not impeded farmers from continuing to use their preferred prediction methods, as on some occasions they continue to be useful for their farming-related decisions and are also the main, or sometimes only, source of forecast. Considering the role these methods play in farmers’ activities, and the limited access to meteorological forecasts in most rural areas of Mozambique, and the fact that the weather and climate is expected to continually change, this paper concludes that it is important to enhance the use of traditional prediction methods. However, the increase of the accuracy and reliability, and continued existence of the methods depends on the farmers’ own abilities to enhance, preserve, and validate them by tailoring the traditional methods used to work with the new environmental, weather, and climatic conditions, or through the development of new methods.

     

An unsustainable state: Contrasting food practices and state policies in the Czech Republic

This paper brings together consideration of food policies and practices and of post-socialist transition to raise neglected questions about means of nurturing more sustainable food systems in the developed world. The last three decades have been marked by the growing salience of food as a political and scholarly concern. While market-based alternative food systems have been heralded for their potential to promote environmental sustainability, the benefits of non-market practices such as household food self-provisioning and barter have been assumed rather than being the focus of research. In the western context, both types of food consumption have positive connotations. Although food self-provisioning in European post-socialist societies is a more wide-spread practice than in western societies, it has been on the periphery of research. The existing literature has conceptualised them as ‘coping strategies’ or as a legacy of irregular supply of goods in the state socialist era. Drawing on empirical research in the Czech Republic, we are proposing a novel approach to the phenomenon of household food production in post-socialist societies as a practice compliant with principles of sustainability. First, we highlight the large extent and social inclusivity of food self-provisioning in Czech society to demonstrate how post-socialist societies are a repository of a rich set of sustainability-promoting consumption practices in relation to food systems. Second, we show that international and domestic policy actors in these societies have ignored these alternative, socially inclusive and environmentally effective practices in favour of far less effective market-based sustainability oriented food policy initiatives. The paper promotes a more integrated view of non-market and market approaches in the pursuit of more sustainable food systems.     

Place and the implications of ‘the local’ for sustainability: an investigation of the Ugu District Municipality in South Africa

Sustainable development is accepted worldwide as a programme for the improvement of human-environment relations. It has been argued that the local level is the optimum level at which to implement sustainability. However, variability of local characteristics problematises this process as engagements with the principles and practices of sustainable development in unique places are likely to result in varying interpretations of the internationally accepted discourses of sustainable development. In order to assess local level interpretations of sustainability [Sharp, L., 1999. Local policy for the global environment: in search of a new perspective. Environmental Politics 8 (4), 137-159] calls for a more contextual analysis of the relationship between sustainability and the local level.This paper evaluates the interpretations of sustainability that were evident in a capacity building workshop in the Ugu District Municipality on the south coast of KwaZulu-Natal in South Africa through consideration of the context in which they emerged. The notion of place as a construction of social and spatial interrelations, the social relations of power within places and the environmental discourses through which debates over sustainability often occur have been used in this study to consider how unequal power relations and the process of political and social transition taking place within the Ugu District Municipality drive the social construction of sustainability agendas. Consequently, the case study draws attention to the need to consider the ways in which local contexts set the terms for interpretations of sustainability as these conceptualizations can direct actions for sustainability and may interrelate to assist or hinder the implementation of local level sustainability plans.     

The ecological and social context of mammal hunting in the coastal savanna of Ghana

This article argues that insufficient attention has been paid in the recent literature to the social and environmental factors which regulate hunting in Ghanaian savannas, and to how this may influence the sustainability of their livelihoods. Despite the vital significance of this issue, the emphasis in the literature and media has been on the destructive impacts of hunting and the bushmeat trade on wildlife. Taking a case study from the coastal savanna of Ghana, a region commonly regarded as a degraded relict of former deciduous forest with a richer wildlife past, it investigates the hypothesis that structure/actor dualities, manifested by socio-cultural change, local environmental knowledge and livelihood activity options, are the primary regulators of hunting intensity and possible sustainability. Such an evaluation is effective if done from a structuration perspective. The integrated methodology incorporates social surveys, GIS based time series image analysis, ecological field methods and statistical analysis. The results provide evidence that the direct and indirect regulatory functions of the socioenvironmental context provide a core feature of the sustainability of hunting. It is concluded that local strategies of resource management may provide an effective complement to conservation policy.     

Mineralogy,petrology and chemistry of lithic fragments from Luna 20 fines: origin of the cumulate ANT suite and its relationship to high-alumina and mare basalts

Bulk analyses of 157 lithic fragments of igneous origin and analyses of their constituent minerals (plagioclase, pyroxene, olivine, Mg-Al spinel, chromite, ilmenite, armalcolite, baddeleyite, zirkelite, K-feldspar, interstitial glass high in SiO₂ and K₂O) have been used to characterize the lunar highland rock suites at the Luna 20 site. The predominant suite is composed of ANT (anorthositic-noritic-troctolitic) rocks, as found at previous Apollo and Luna sites. This suite consists of an early cumulate member, spinel troctolite, and later cumulate rocks which are gradational from anorthosite to noritic and troctolitic anorthosite to anorthositic norite and troctolite; anorthositic norite is the most abundant rock type and its composition is close to the average composition for the highland rocks at this site. Spinel troctolite is a distinctive member of this suite and is characterized by the presence of Mg-Al spinel, magnesian olivine (average, Fo₈₃), and plagioclase. High-alumina basalt with low alkali content is another important rock type and melt of this composition may be parental to the cumulate ANT suite. Alkalic high-alumina basalt (KREEP) was not found in our sample, but may be genetically related to the ANT suite in that it may have formed by partial melting of rocks similar to those of the ANT suite. Fractional crystallization of low alkali, high-alumina basalt probably cannot produce alkalic high-alumina basalt because the enrichment in KREEP component is many times greater than the simultaneous change in major element components. Formation of alkalic high-alumina basalt by mechanical mixing of ANT rocks with very KREEP-rich components is not likely because the high-alumina basalt suite falls on a cotectic in the anorthiteolivine-silica system. Mare basalts may also be genetically related in that they may have been derived by remelting of rocks formed from residual liquids of fractional crystallization of parental low-alkali, high-alumina basalt, plus mafic cumulate crystals; the resultant melt would have a negative Eu anomaly and high $\text{Fe}\text{Mg}$ and $\text{pyroxene}\text{plagioclase}$ ratios.     

The rise of territorial eco-certifications: New politics of transnational sustainability governance in the fishery sector

Eco-certifications have become an important site of power struggles in commodity sectors such as forestry, fisheries, aquaculture, palm oil, and soy. In each, multiple eco-certification initiatives have been developed and resisted through interactions among non-governmental organizations, governments, and commercial actors. This paper contributes to understanding how power is embodied in certifications by exploring how territoriality manifests in the international struggle over defining what products are ‘sustainable’ and which producers will have access to markets that require ‘sustainable’ products. Focusing on the wild capture fisheries sector in which the non-governmental Marine Stewardship Council (MSC) administers the preeminent eco-certification initiative, we explore the emergence of new fisheries eco-certification initiatives in Japan, Iceland, Alaska, Canada, and the US that insist there is no transnational monopoly on judgments over fisheries sustainability. We argue that these new eco-certifications attempt to defend and embed territorial social and regulatory relations of production within the contested domain of transnational sustainability governance. The initiatives accommodate both the territorially embedded material interests, institutions, and discursive strategies of producers (and their state supporting agencies) and transnationally embedded governance norms for assessing and communicating sustainability. They also counter the globally applicable institutions of the MSC in favor of making space for state and non-state actors to contend with demands for sustainability in the global seafood market by combining place-specific attributes with transnational governance norms.

The impact of severe natural disasters on the livelihoods of farmers in mountainous areas: a case study of Qingping Township,Mianzhu City

The ‘5.12’ earthquake in 2008 and the ‘8.13’ debris flow in 2010 brought huge losses of life and property to Qingping Township. Farmers’ livelihoods assets were also seriously affected and damaged. These led to a change in farmers’ livelihood styles and reduction in their income. A study of the impact of natural disasters on farmers’ livelihoods in mountainous areas would have significant importance for policy making. Based on field survey data from sample households, this study comparatively analyzed the assets, livelihood styles and income of farmers over three periods—2007, 2009 after the ‘5.12’ earthquake, and 2 months after ‘8.13’ debris flows. It presents the following findings: (1) livelihood assets suffered heavy losses; (2) livelihood styles were significantly changed; and (3) the sustainability of farmer income was adversely influenced. These results suggest that, during the process of post-disaster reconstruction work, affected farmers’ security, the carrying capacity of livelihood assets, and the enhancement of employment and livelihood choice are worthy of much attention from policy makers.
