Ecological Functions and Functionings: Towards a Senian Analysis of Ecosystem Services

Ecosystem services are part of a growing trend within environment and development to analyse environmental change within the context of socially valued outcomes. Yet, ecosystem services‐based policies and analyses are increasingly criticized for failing to connect with, or even for restricting, development outcomes. This article seeks to connect environmental analysis with development outcomes better by applying the capability approach of Amartya Sen and others. It demonstrates how scientific analysis of ecosystem services sometimes conflates pathways of ecosystem management with development outcomes, but that it can be reconfigured to include more diverse values and objectives. The article argues that ecosystem services should be identified more as ‘functionings’ (in the Senian sense of valued development outcomes) rather than ‘functions’ (in the sense of biophysical, apolitical ecosystem properties) in order to indicate that ‘services’ always reflect social values, and that values and scientific explanations of underlying biophysical properties evolve together. Environmental science for socially valued outcomes such as ecosystem services is therefore an important site of political inclusion and exclusion. The article illustrates this analysis with examples of ecosystem‐based adaptation to climate change from the World Bank and government of Bangladesh, and in contrast to differing approaches from the field of sustainability science.     

The importance of communal forests in carbon storage: Using and destabilizing carbon measurement in understanding Guatemala's payments for ecosystem services

Payments for ecosystem services (PES) are a conservation initiative that offer payments to people who own or manage lands that provide desired ecosystem services. Utilizing mixed methods, I examine how PES in the form of government-issued forestry incentives interact with land tenure to affect carbon storage in Guatemala's Western Highlands. Land tenure is a larger determining factor for carbon storage than payments, as communal forests managed by Indigenous Maya K'iche' communities have significantly higher carbon stocks than private landholdings in these same communities. No statistically significant differences were found in carbon stocks between incentivized and non-incentivized plots, and participants enrolled only a fraction of their land, likely prioritizing enrollment of degraded plots. These results indicate the importance of using both social and physical science methods to understand the physical outcomes and social context of forest management. I also reflect on why carbon storage is often prioritized, drawing on a critical physical geography framework to analyze carbon accounting methods. Measuring carbon storage gives us the tools to describe the success of communal forest management, yet I also caution relying on the quantification of ecosystem services as a method for landscape valuation and suggest avoiding prioritizing carbon storage and sequestration.     

Entrepreneurial Ecosystems and Regional Policy: A Sympathetic Critique

Regional policies for entrepreneurship are currently going through a transition from increasing the quantity of entrepreneurship to increasing the quality of entrepreneurship. The next step will be the transition from entrepreneurship policy towards policy for an entrepreneurial economy. The entrepreneurial ecosystem approach has been heralded as a new framework accommodating these transitions. This approach starts with the entrepreneurial actor, but emphasizes the context of productive entrepreneurship. Entrepreneurship is not only the output of the system, entrepreneurs are important players themselves in creating the ecosystem and keeping it healthy. This research briefing reviews the entrepreneurial ecosystem literature and its shortcomings, and provides a novel synthesis. The entrepreneurial ecosystem approach speaks directly to practitioners, but its causal depth and evidence base is rather limited. This article provides a novel synthesis including a causal scheme of how the framework and systemic conditions of the ecosystem lead to particular entrepreneurial activities as output of the ecosystem and new value creation as outcome of the ecosystem. In addition it provides a framework for analysing the interactions between the elements within the ecosystem. This offers a much more rigorous and relevant starting point for subsequent studies into entrepreneurial ecosystems and the regional policy implications of these.     

Gender and Environment: Some preliminary questions about women and water in the South Australian context

This paper speculates on three issues about the relationship between women and water, focusing on the context of South Australia, a particularly dry part of the world. First, it is suggested that gender affects our connections to environmental resources, in this instance to water. Second, it is noted that currently unexamined archival material exists for the South Australian situation and that the analysis of this material may shed light on the relationship between gender and environmental resources. Third, it is possible to argue that the conflation of nature and the feminine through such things as tropic devices in language results in both being constituted largely as corporeal, as bodies requiring management. Such a possibility suggests that a body politics exists in environmental studies and related disciplines that requires further theoretical work.     

ENVIRONMENTAL ISSUES IN SOVIET FOREST MANAGEMENT

Exploitation of forest resources in the USSR requires choices among a set of uses which are at times mutually exclusive. Trees have predominantly been used in industry, often harvested by methods which have caused environmental damage and have not allowed for optimum utilization of the resource. It appears that increasing recognition is given to other functions of forest stands, including food supply, social recreation, and non-consumptive uses such as ecosystem preservation and environmental amelioration.     

The platform business model and business ecosystem: quality management and revenue structures*

A platform is a two-sided market. It is an environment established to allow multiple groups such as suppliers and consumers to exchange their views for fair transactions. Platforms evolve through the connection and interaction of participants, and act as ecosystems of coexistence that can provide values and benefits to all participants. Care must be taken in building such a business ecosystem to successfully stabilize the platform model. This research indicates how a business ecosystem can be constructed by analysing quality management and revenue structures – core elements in any platform business model with a distinct group of users on either side. Through 12 case studies using 30 in-depth interviews and 2 focus group interviews, this research suggests the conceptual framework, ‘12 different types of quality management and revenue structure strategies’. These will serve as the conceptual framework from which to build platform business model ecosystems.     

The Internal Circulation of Matter in the Principal Types of Natural Ecosystems of the USSR

The internal biological circulation of matter in zonal ecosystems may be characterized in terms of the degree of self-containment, meaning the capacity of the ecosystem to make full use of organic matter without losing any to the outside or letting it accumulate uselessly within the system. The circulation may also be characterized in terms of the rate of circulation and the structure of circulation. These criteria are used to describe the main zonal ecosystems of the USSR (tundra, tayga, broadleaf forest, steppe, desert). Tundra and tayga are found to suffer from incomplete circulation with heavy loss of biogens; broadleaf forest and steppe are the most productive. The impact of human activity on each natural ecosystem is analyzed.     

The role of forests in global climate change: whence we come and where we go

Neither the United Nations Framework Convention on Climate Change (UNFCCC) nor the Kyoto Protocol include a satisfying mechanism for reducing the substantial emissions from deforestation which are responsible for about a quarter of global greenhouse gas emissions. It is acknowledged that planting forests, for example through afforestation and reforestation in the Clean Development Mechanism, clearly provides an opportunity to sequester carbon in vegetation and soils. However, it takes decades to restore carbon stocks that have been lost as a result of land-use changes. Reducing the rate of deforestation is the only effective way to reduce carbon losses from forest ecosystems. As negotiations on a post-Kyoto agreement have already started the authors argue that a complete and fair post-Kyoto regime will have to expand existing regulations by creating a framework to encompass all land-use and forest-related changes in carbon stocks. Developing countries administer the majority of the world's environmental resources and provide a vital global public good by maintaining environmental assets. However, with increasing pressure on development and the use of resources, developing countries can hardly be expected to provide these services free. Therefore, they will have to be integrated into a more comprehensive incentive framework which also rewards forestry conservation, sustainable forest management and afforestation. The authors discuss how an incentive system for the protection of forests can be included in a future climate regime. Different design choices are considered and two recent approaches to reward developing countries that avoid further deforestation are compared: the 'compensated reduction of deforestation' approach and the Carbon Stock Approach.     

Translating Water Fund Payments for Ecosystem Services in the Ecuadorian Andes

As a form of environmental governance, Payments for Ecosystem Services (PES) is imbued with ideological values that can conflict with those of participating rural communities. The discursive frame surrounding PES may be contentious, even if the conservation activities promoted by these initiatives are not. Moving PES into practice therefore requires a process of translation from urban-based practitioners to rural communities. Drawing upon an empirical case study of FONAG, a water fund from Ecuador that is often promoted as the ideal type, this article employs data from participant observation, key informant interviews and textual materials to examine this process of translation. The article focuses particularly on the efforts to negotiate the discourse of PES that move the projects into on-the-ground practice. While Ecuador's political context has softened the emphasis on economically valuing ecosystem services, FONAG uses neoliberal conservation narratives that identify rural poverty as the main cause of environmental degradation and target the reform of local people through economic incentives. To enrol communities, however, intermediaries are needed to translate water fund PES to appeal to local perspectives, values and institutions. The author argues that contrasting narratives of PES can exist simultaneously between the entities that are implementing PES and the targets of that implementation.     

The Green Economy Research Centre – positioning geographical research in Aberdeen to address the challenges of green economy transitions

ABSTRACT

The necessity to address climate change has resulted in a widespread debate about the need for a transition to a ‘greener’ economy. How such an economy emerges, by what drivers and at what scale is a significant source of speculation amongst the geographical research community. In the context of longstanding contributions to environmental geography from scholars working at Aberdeen University, this paper outlines a novel research agenda for the Green Economy Research Centre (GERC). The contours of the green economy are examined in the context of economic sectors of food production, tourism, energy and the blue economy. Cross-cutting themes of green transitions, governance, people and place and ecosystem services inform our academic contribution to this evolving and controversial societal issue.     

The new killer drones: understanding the strategic implications of next‐generation unmanned combat aerial vehicles

The expansive use of armed unmanned combat aerial vehicles (UCAV), or ‘drones’, by the United States over the past decade has occurred within a particular strategic context characterized by irregular warfare operations in permissive environments. Ongoing strategic, ethical and moral debates regarding specific uses of drones may well be overtaken by a new generation of armed combat drones able to survive and operate in contested airspace with design elements such as stealth and greater levels of machine autonomy. These design parameters, and the likely strategic context within which second generation UCAVs will be deployed, suggest a fundamentally different set of missions from those performed by the current generation of drones. The most beneficial characteristic of current unmanned systems has been the ability to combine persistent surveillance with the delivery of small precision‐guided munitions. With a shift to more contested environments, this type of armed surveillance mission may become less practical and second generation UCAVs will instead focus on high intensity warfare operations. These new systems may have significant implications for deterrence, force doctrine and the conduct of warfare.     

Aquatic resources in human diet in the Late Mesolithic in Northern France and Luxembourg: insights from carbon,nitrogen and sulphur isotope ratios

We investigated the contribution of freshwater resources to the diet of seven Late Mesolithic hunter-gatherers (ca. 5300–7000 BC) from Northern France and Luxembourg using stable isotope ratios. In addition to the carbon and nitrogen stable isotope ratios (δ¹³C, δ¹⁵N), we explored the potential of the sulphur isotopic ratios (δ³⁴S) to detect and quantify the proportion of protein derived from aquatic foodstuff. In only two sites, animal remains from an associated settlement were available and subsequently examined to decipher the isotopic differential between terrestrial and freshwater resources. The quantification of their relative contribution was simulated using a Bayesian mixing model. The measurements revealed a significant overlap in δ¹³C values between freshwater and terrestrial resources and a large range of δ¹⁵N values for each food category. The δ³⁴S values of the aquatic and terrestrial animals were clearly distinct at the settlement in the Seine valley, while the results on fish from Belgium demonstrated a possible overlap in δ³⁴S values between freshwater and terrestrial resources. Local freshwater ecosystem likely contributed to ca. 30–40 % of the protein in the diet of the individuals found in the Seine settlement. Out of this context, the isotopic signature and thus contribution of the available aquatic foods was difficult to assess. Another potential source of dietary protein is wild boar. Depending on the local context, collagen δ³⁴S values may contribute to better assessment of the relative contribution of freshwater and terrestrial resources.     

Protecting aquatic ecosystems in heavily allocated river systems: the case of the Oldman River Basin,Alberta

Initiatives aimed at protecting aquatic ecosystems often prove difficult to implement—particularly in water‐stressed, semi‐arid regions where the demand for water for human consumption is high. This article reports on an investigation of the factors that shaped the development and implementation of policies for aquatic ecosystem protection in the Oldman River Basin (ORB), a crucial watershed in semi‐arid southern Alberta. The analysis reveals critical cultural and historical considerations that confront those attempting to protect and restore aquatic ecosystems in the ORB and highlights specific factors that influence implementation of measures to protect it. In addition to the most basic consideration—demand for water exceeds supplies—eight specific factors that influenced aquatic ecosystem protection in this region are identified and evaluated. These include (1) clarity of actors’ roles/ jurisdictional responsibilities; (2) communication; (3) definition of key terms; (4) funding and organizational capacity; (5) leadership; (6) legal standing; (7) data and monitoring; and (8) public education. We argue that while these factors are important, critical cultural and historical considerations that influence water policy in the province also must be addressed in any efforts to protect aquatic ecosystems in southern Alberta.     

The Broad Spectrum Revolution at 40: Resource diversity,intensification, and an alternative to optimal foraging explanations

More than 40 years ago Kent Flannery coined the term Broad Spectrum Revolution (BSR) in reference to a broadening of the subsistence base of Late Pleistocene hunter–gatherers in the Near East that preceded and helped pave the way for the domestication and plants and animals and the emergence of agriculture. Set within a demographic density model that projected differential rates of population growth and emigration in different resource zones of the Near East, Flannery’s BSR quickly became a global construct linking resource diversification and intensification to imbalances between population and environmental carrying capacity. In recent years the BSR has proven especially attractive to researchers working within an optimal foraging theory (OFT) framework in which diversification and intensification of subsistence only occurs within the context of resource depression, caused by either demographic pressure or environmental deterioration. This OFT perspective, that situates human societies in a one-way adaptive framework as they are forced to adapt to declining availability of optimal resources, however, is increasingly being called into question. Numerous examples of diversification and intensification are being documented in contexts of resource abundance shaped, in part, by deliberate human efforts at ecosystem engineering intended to promote resource productivity. An alternative approach, framed within a newer paradigm from evolutionary biology, niche construction theory (NCT), provides a more powerful explanatory framework for the BSR wherever it occurred.

Rewilding – A New Paradigm for Nature Conservation in Scotland?

Abstract

Rewilding is a strategy for the conservation of complete, self-sustaining ecosystems, primarily involving the protection and, where necessary, reintroduction, of populations of keystone species in large, connected reserve networks. A potential method of preserving ecosystem functions and biodiversity, it is now receiving a great deal of practical and political attention, particularly in North America. In Scotland, where many native species have been extirpated in the relatively recent past, rewilding has clear relevance and may provide an overarching set of objectives for current programmes of native woodland restoration and species reintroductions. Nevertheless, rewilding is not widely used as a term or strategy in Scottish conservation. This review considers the development of the concept and its possible application in Scotland, and identifies substantial scope for rewilding, in terms of the restoration and protection of large areas of wild land, and of the reintroduction of native species which have been driven to extinction by human activity. As the environmental, social and economic benefits which are likely to result from a programme of rewilding in Scotland outweigh the potential drawbacks, the adoption of rewilding is recommended as one aim of environmental policy.     

A political economy approach to the allocation of health care resources: the case of remote areas of Queensland

This article describes and accounts for the existing distribution of medical services in remote areas. In contrast to traditional geographical approaches which have sought to explain problems associated with service provision in remote areas in terms of high costs of overcoming vast distances and low population thresholds, it is argued that such geographical and economic factors alone are an insufficient basis for explanation. Rather, it is necessary to view this issue in the broader context of existing ideology that underpins the procedures relating to the allocation of society's scarce resources, and the role of political and bureaucratic processes that are responsible for health care inequities. The adoption of apolitical economy framework recognises the problem of resource allocation as essentially a political matter requiring an analysis of power relations.     

Incidental heritage: difficult intangible heritages as collateral damage

Within the context of ‘negative’ and ‘intangible heritage,’ this paper explores Burström and Gelderblom’s proposition of ‘difficult heritage,’ with respect to Bückeberg, the site of the Third Reich Harvest Festival, as a site where collective moments of cultural shame occur. The paper then considers homelessness within this theoretical framework to ask whether those aspects of our inherited and contemporary culture, which are difficult and culturally shameful, are able to be accommodated within the framework of intangible heritage. It proposes homelessness as difficult intangible heritage which is produced as ‘collateral damage,’ an indirect byproduct of other pro-active cultural processes and community values.
