Land use is central to addressing sustainability issues, including biodiversity conservation, climate change, food security, poverty alleviation, and sustainable energy. In this paper, we synthesize knowledge accumulated in land system science, the integrated study of terrestrial social-ecological systems, into 10 hard truths that have strong, general, empirical support. These facts help to explain the challenges of achieving sustainability in land use and thus also point toward solutions. The 10 facts are as follows: 1) Meanings and values of land are socially constructed and contested; 2) land systems exhibit complex behaviors with abrupt, hard-to-predict changes; 3) irreversible changes and path dependence are common features of land systems; 4) some land uses have a small footprint but very large impacts; 5) drivers and impacts of land-use change are globally interconnected and spill over to distant locations; 6) humanity lives on a used planet where all land provides benefits to societies; 7) land-use change usually entails trade-offs between different benefits-"win-wins" are thus rare; 8) land tenure and land-use claims are often unclear, overlapping, and contested; 9) the benefits and burdens from land are unequally distributed; and 10) land users have multiple, sometimes conflicting, ideas of what social and environmental justice entails. The facts have implications for governance, but do not provide fixed answers. Instead they constitute a set of core principles which can guide scientists, policy makers, and practitioners toward meeting sustainability challenges in land use.

Increasing evidence-synthesized in this paper-shows that economic growth contributes to biodiversity loss via greater resource consumption and higher emissions. Nonetheless, a review of international biodiversity and sustainability policies shows that the majority advocate economic growth. Since improvements in resource use efficiency have so far not allowed for absolute global reductions in resource use and pollution, we question the support for economic growth in these policies, where inadequate attention is paid to the question of how growth can be decoupled from biodiversity loss. Drawing on the literature about alternatives to economic growth, we explore this contradiction and suggest ways forward to halt global biodiversity decline. These include policy proposals to move beyond the growth paradigm while enhancing overall prosperity, which can be implemented by combining top-down and bottom-up governance across scales. Finally, we call the attention of researchers and policy makers to two immediate steps: acknowledge the conflict between economic growth and biodiversity conservation in future policies; and explore socioeconomic trajectories beyond economic growth in the next generation of biodiversity scenarios.
From teleconnection to telecoupling: taking stock of an emerging framework in land system science
2015Journal of Land Use Science · 182 Zitationen · DOI
Land use change is influenced by a complexity of drivers that transcend spatial, institutional and temporal scales. The analytical framework of telecoupling has recently been proposed in land system science to address this complexity, particularly the increasing importance of distal connections, flows and feedbacks characterising change in land systems. This framework holds important potential for advancing the analysis of land system change. In this article, we review the state of the art of the telecoupling framework in the land system science literature. The article traces the development of the framework from teleconnection to telecoupling and presents two approaches to telecoupling analysis currently proposed in the literature. Subsequently, we discuss a number of analytical challenges related to categorisation of systems, system boundaries, hierarchy and scale. Finally, we propose approaches to address these challenges by looking beyond land system science to theoretical perspectives from economic geography, social metabolism studies, political ecology and cultural anthropology.
Cooperation and Conflict · 146 Zitationen · DOI
Environmental peacebuilding represents a paradigm shift from a nexus of environmental scarcity to one of environmental peace. It rests on the assumption that the biophysical environment’s inherent characteristics can act as incentives for cooperation and peace, rather than violence and competition. Based on this, environmental peacebuilding presents cooperation as a win-win solution and escape from the zero-sum logic of conflict. However, there is a lack of coherent environmental peacebuilding framework and evidence corroborating the existence of this environment-peace nexus. Building on a multidisciplinary literature review, this article examines the evolution of environmental peacebuilding into an emerging framework. It unpacks the concept and explains its main building blocks (conditions, mechanisms and outcomes) to develop our understanding of when, how and why environmental cooperation can serve as a peacebuilding tool. It assembles these building blocks into three generic trajectories (technical, restorative and sustainable environmental peacebuilding), each characterised according to their own causality, drivers and prerequisites, and illustrated with concrete examples. Finally, this article draws attention to the remaining theoretical gaps in the environmental peacebuilding literature, and lays the foundations for an environmental peacebuilding research agenda that clarifies if and how environmental cooperation can spill over across borders, sectors and scales towards sustainable peace.

Increasing attention is being paid to the role of social networks in climate change research and new studies show that they form an essential source of resilience. However, the role of social networks remains underexplored as there is only limited empirical evidence of their benefits, particularly for research on adaptation to climate change in developing countries. This paper provides a contribution to this field of research by examining how social networks foster livelihood diversification and resilience in a small rural community in northern Ghana. The study combines semi-structured interviews, focus group discussions and a survey with a range of other participatory methods. The findings show that, people in the studied community have experienced a range of climatic changes with negative impacts on agriculture in the last three decades. These climatic changes have forced community members to diversify their livelihood activities away from crop production and into off-farm and non-farm activities. Our results highlight how the process of diversification is dependent on household participation in various group activities and formal and informal social networks. Further, the households participating in several group activities and social networks had more diverse livelihood strategies and were found to be more resilient to perceived climate changes because they had access to the critical resources (material and non-material) essential for diversification through their networks. Importantly, this study shows how group activities and social networks can also create adverse effects by enforcing exclusion and marginalization among certain groups in the community. In addition, it shows how some diversification strategies are in conflict with others and thus may potentially undermine future adaptive capacity and the resilience of the community as a whole.

The scholarly debate around ‘global land grabbing’ is advancing theoretically, methodologically and empirically. This study contributes to these ongoing efforts by investigating a set of ‘small-scale land acquisitions’ in the context of a recent boom in banana plantation investments in Luang Namtha Province, Laos. In relation to the actors, scales and processes involved, the banana acquisitions differ from the state-granted large-scale land acquisitions dominating the literature on ‘land grabbing’ in Laos. Starting from the experience of a rural village in Laos, where two Chinese banana investors leased land on six-year contracts in 2010, we trace the strategies employed by the investors to gain access to the land, the experience of the villagers in the process and the outcome of the acquisitions in terms of land use change. The findings reveal how the investors established networks of local middlemen who facilitate negotiations over land directly at the village level, thus enabling them to circumvent any formal involvement of government authorities. The informal acquisition process also ensured a rapid and successful implementation of the plantations with consequent land use change, including the destruction of field structures, plot borders and irrigation systems, as well as erosion and heavy chemical input. Drawing upon the literature on ‘powers of exclusion’ and ‘control grabbing’, the paper argues that despite the apparent small-scale and short-term nature of these leases, the forceful acquisition strategies pursued by the investors coupled with the rapid land use conversion and associated cultivation practices results in strong and longer-term alienation of land from the local communities involved. This implies the need to take these more informal forms of land acquisitions into account when designing policies to address the negative implications of land grabbing in Laos and elsewhere.

Abstract Rural development in the Sudano‐Sahelian region during the past 20 years and future scenarios of change were studied using meta‐analysis of case studies, household interviews and scenario assessment. Households have generally increased their wealth, especially when they diversify out of agriculture. Rain‐fed crop cultivation is more sensitive to climate factors than livestock, but generally climate factors play a limited direct role for local land use and livelihood strategies. The agricultural sector needs strong support to remain important in the region and off‐farm work and migration are likely to continue to increase, which may decrease vulnerability.

Rapid urban expansion is a significant contributor to land cover change and poses a challenge to environmental sustainability, particularly in less developed countries. Insufficient data about urban expansion hinders effective land use planning. Therefore, a high need to collect, process, and disseminate land cover data exists. This study focuses on urban land cover change detection using Geographic Information Systems and remote sensing methods to produce baseline information in support for land use planning. We applied a supervised classification of land cover of LANDSAT data from 1987, 2002, and 2017. We mapped land cover transitions from 1987 to 2017 and computed the net land cover change during this time. Finally, we analyzed the mismatches between the past and current urban land cover and land use plans and quantified the non-urban development area lost to urban/built-up. Our results indicated an increase in urban/built-up and bare land cover types, while vegetation land cover decreased. We observed mismatches between past/current land cover and the existing land use plan. By providing detailed insights into mismatches between the regional land use plan and unregulated urban expansion, this study provides important information for a critical debate on the role and effectiveness of land use planning for environmental sustainability and sustainable urban development, particularly in less developed countries.
Allergy · 72 Zitationen · DOI
In a retrospective study, all cases of anaphylactic shock (AS) occurring in a hospital catchment area during a 13-year period were analysed. Twenty cases were found, giving an incidence of 3.2 cases per 100,000 inhabitants per year, and one patient died. The precipitating agents were penicillin (7 cases), aspirin (3), food (2), and bee or wasp sting (8). The drugs had all been given orally. Penicillin-related AS was much commoner than its incidence reported by the Danish national health authorities. In three cases, previous anaphylactic reactions had occurred to the agent in question. We concluded that AS rarely occurs outside hospital, but that oral penicillin is a more important cause than was previously thought. Many recurring episodes of AS should be preventable, since hypersensitivity tests for both penicillin and hymenoptera venoms are available, and hyposensitization with respect to the latter is feasible.

Science should provide solutions for societal transformations towards sustainability in the face of global environmental change. Land system science, as a systemic science focused on complex socioecological interactions around land use and associated trade-offs and synergies, is well placed to contribute to this agenda. This goal requires a stronger engagement with the normative implications of scientific practice, research topics, questions and results. We identify concerns as well as three concrete steps for land system science to more deeply contribute in normative issues. In particular, we encourage land system scientists to discuss explicitly the normative questions, values, perspectives and assumptions already present in our research, as well as to identify key normative research questions to contribute to societal transformations.

Land-based production provides societies with indispensable goods such as food, feed, fibre, and energy. Yet, with economic globalisation and global population growth, the environmental and social trade-offs of their production are ever more complex. This is particularly so since land use changes are increasingly embedded in networks of long-distance flows of, e.g., material, energy, and information. The resulting scientific and governance challenge is captured in the emerging telecoupling framework addressing socioeconomic and environmental interactions and feedbacks between distal human-environment systems. Understanding telecouplings, however, entails a number of fundamental analytical problems. When dealing with global connectivity, a central question is how and where to draw system boundaries between coupled systems. In this article, we explore the analytical implications of setting system boundaries in the study of a recent telecoupled land use change: the expansion of Chinese banana plantation investments in Luang Namtha Province, Laos. Based on empirical material from fieldwork in Laos in 2014 and 2015, and drawing on key concepts from the ‘systems thinking’ literature, we illustrate how treating the system and its boundaries as epistemological constructs enable us to capture the differentiated involvement of actors, as well as the socio-economic and environmental effects of this land use change. In discussing our results, the need for more explicit attention to the trade-offs and implications of scale and boundary choices when defining systems is emphasised.

The over-all uncorrected prevalence rates of bilharziasis determined in this survey were-Control Division, 59.5%; Rural and Reclamation Divisions, 35.9%; Urban Division, 21.0%. There are significant differences in rates of infection between sections within a division, between adjacent villages and even between different parts of one village. Prevalence increases rapidly with age up to about the age of 14 years, declines somewhat up to the age of 40 years and then remains fairly constant at a rate of about 30%; the age-group 0-8 years should provide the most sensitive group for the assessment of control measures. S. mansoni infection is acquired more slowly than S. haematobium infection during childhood and is more persistent among adults.Except for the youngest age-group, bilharziasis rates are higher in males than in females, but more detailed analysis shows that this is true only for farmers and farm labourers and for those who swim. In respect of occupational categories, farmers and farm labourers, with prevalence rates of 50.6% and 41.6%, respectivelx, bear the brunt of the infection, since they constitute 48% of the population, although fishermen (60.4%) and boatmen (52.0%) have higher infection rates.Differences in bilharziasis rates can also be related to differences in religion, educational attainment and domestic habits (swimming, washing clothes, utensils and cattle) according to the opportunity provided for contact with polluted water. Swimming, because of the thorough exposure to possible schistosome infection that it provides, is one of the most important activities involved in the transmission of bilharziasis.

Participatory planning networks made of government agencies, stakeholders, citizens and scientists are receiving attention as a potential pathway to build resilient landscapes in the face of increased wildfire impacts due to suppression policies and land-use and climate changes. A key challenge for these networks lies in incorporating local knowledge and social values about landscape into operational wildfire management strategies. As large wildfires overcome the suppression capacity of the fire departments, such strategies entail difficult decisions about intervention priorities among different regions, values and socioeconomic interests. Therefore there is increasing interest in developing tools that facilitate decision-making during emergencies. In this paper we present a method to democratize wildfire strategies by incorporating social values about landscape in both suppression and prevention planning. We do so by reporting and critically reflecting on the experience from a pilot participatory process conducted in a region of Catalonia (Spain). There, we built a network of researchers, practitioners and citizens across spatial and governance scales. We combined knowledge on expected wildfires, landscape co-valuation by relevant actors, and citizen participation sessions to design a wildfire strategy that minimized the loss of social values. Drawing on insights from political ecology and transformation science, we discuss what the attempt to democratize wildfire strategies entails in terms of power relationships and potential for social-ecological transformation. Based on our experience, we suggest a trade-off between current wildfire risk levels and democratic management in the fire-prone regions of many western countries. In turn, the political negotiation about the landscape effects of wildfire expert knowledge is shown as a potential transformation pathway towards lower risk landscapes that can re-define agency over landscape and foster community re-learning on fire. We conclude that democratizing wildfire strategies ultimately entails co-shaping the landscapes and societies of the future.
