Regelmäßige Landschaftsbrände sind ein wesentlicher Bestandteil vieler Ökosysteme wie Savannen oder Trockenwäldern. In vielen Regionen der Welt sind die Brände größer und häufiger geworden. Brände in den Wäldern der Gebiete mit gemäßigtem Klima wie Deutschland sind eigentlich nicht ökosystemtypisch. Aktuell nehmen allerdings die Häufigkeit und Anzahl sowie die Größe von Waldbränden zu, ohne dass Gesellschaft und Politik darauf angemessen vorbereitet sind.
As the risk of forest fires increases around the globe, the issues of how to control, suppress, and prevent them are the subjects of growing public and political attention. This study focuses on the political debate in Germany regarding forest fires and provides insights into the conceptualization of forest fires and forest fire management at the federal and state policymaking levels. By examining forest fire narratives through the policy lens, this case study takes an exemplary extreme weather event exacerbated by climate change as an opportunity to examine the policy response to this problem. In this way, we examine the role of policy narratives in civil and environmental protection and disaster management. The findings reveal that all politicians examined in this study agree that forest fire management is an urgent matter that needs to be supported. In the prevailing human-centered narrative, policymakers see active forest management and use as tools to improve forest resilience to fire and other calamities. Those who advocate a nature-based narrative assert that it is natural processes in protected forest areas that most effectively enhance resilience. The policy solutions derived from these views include financial support, recognition of the work of foresters, forest fire managers, and civil protection agencies as well as, depending on the type of narrative argument favored, either increased forest management or improved protection of forest ecologies. This suggests that narrative analysis may illuminate the rationales underlying previous policy decisions and the framework for future ones. This contribution throws light on how narratives shape policymaking and, by extension, disaster management. Future studies should therefore take into account the influence of prevailing narratives when it comes to evaluating the potential that policymaking can offer for disaster management in the future.
Scholars have argued that circular economy (CE) must be upscaled and globalized to address excessive resource extraction and waste generation. Many CE practitioners consider the first international CE agreement between China and the EU a milestone towards such an effort. This analysis shows why this expectation is premature. European and Chinese stakeholders’ optimistic and depoliticized CE narratives disable communication regarding development disparities, negative competition and distrust, which shape geopolitical rivalry. While skeptical narratives that address political barriers exist, they fall short of suggesting alternatives. Based on 72 stakeholder interviews, 40 documents and participant observation, these results highlight the critical importance of investigating narrative strategies to repoliticize environmental cooperation. Such narrative strategies would support contestation and negotiation on development disparities and open channels for joint conceptualization of implementation scales for environmental strategies, circular or otherwise. We therefore propose using constructivist perspectives of international relations to explore discursive barriers and enablers to global environmental action.
Dem Wald in Deutschland geht es schlecht. Seit 2018 machen außergewöhnliche Wärme und Trockenheit vielen Bäumen zu schaffen. Von einem »Waldsterben 2.0« ist die Rede. Die Interpretationen der Genese der aktuellen Waldkrise sowie die strategischen Ideen zu ihrer Bekämpfung gehen zwar weit auseinander - aber die Einschätzung, dass die aktuelle Verkettung von extremen Witterungen und die entsprechenden Konsequenzen in den Wäldern eine Zäsur darstellt, ist weitgehend Konsens. Die zentrale Frage ist, ob die Krise Anlass zu einer tiefgreifenden Reflektion über das vorherrschende Management der Waldökosysteme und eine entsprechende »Waldwende« gibt oder ob die aktuellen Reaktionen von Politik und Forstwirtschaft sogar zur Verschärfung der Situation beigetragen.
Intact forests contribute to the ecosystem functionality of landscapes by storing and sequestering carbon, buffering and cooling the microclimate, and providing a range of related ecosystem functions. Forest fragmentation not only poses a threat to many organisms but also reduces the resistance and resilience of the ecosystem, which is especially relevant to the ongoing climate crisis. The effects of recent extreme heat years on forests in Germany have not been studied in detail for the influence of fragmentation. We investigate the relation of forest fragmentation with temperature and vitality in Germany per ecoregion at the canopy level using satellite imagery at 1-km and 30-m resolution. We compiled and correlated forest maps for connectivity based on Thiessen polygons, canopy temperatures on the hottest days based on land surface temperature, and forest vitality based on the maximum normalized difference vegetation index per growing season. We differentiated between ecoregions and main forest types. In 2022, larger intact tree-covered areas that are less fragmented have relatively low temperatures on hot days and higher overall vitality. Nearly 98% of the almost 1.95 million forest fragments at 30-m resolution in Germany are smaller than 1 km2, which cover nearly 30% of the total forest area. To counteract the forest crisis, forest and landscape management should aim to reduce fragmentation and maintain tree biomass and forest cover in the landscape. Increasing the size of continuous forest fragments contributes to ecosystem-based adaptation to climate change.
Analysis of urban dynamics is a pivotal step towards understanding landscape changes and developing scientifically sound urban management strategies. Delineating the patterns and processes shaping the evolution of urban regions is an essential part of this step. Utilizing remote-sensing techniques and Geographic Information System (GIS) tools, we performed an integrated analysis on urban expansion in Srinagar city and surrounding areas from 1999 to 2017 at multiple scales in order to assist urban planning initiatives. To capture various spatial indicators of expansion, we analysed (i) land use/land cover (LULC) changes, (ii) rate and intensity of changes to built-up areas, (iii) spatial differentiation in landscape metrics (at 500, 1000 and 2000 m cell-size), and (iv) growth type of the urban expansion. Global Moran’s I statistics and local indicators of spatial association (LISA) were also employed to identify hotspots of change in landscape structure. Our methodology utilizes a range of geovisualization tools which are capable of appropriately addressing various elements required for strategic planning in growing cities. The results highlight aggregation and homogenization of the urban core as well as irregularity and fragmentation in its periphery. A combination of spatial metrics and growth type analysis supports the supposition that there is a continuum in the diffusion-coalescence process. This allows us to extend our understanding of urban growth theory and to report deviations from accepted stages of growth. As our results show, each dominating growth phase of the city—both diffusion (1999) and coalescence (2009 and 2017)—is interspersed with features from the other type. An improved understanding of spatial differentiation and the identification of hotspots can serve to make urban planning more tailored to such local conditions. An important insight derived from the results is the applicability of remote-sensing data in urban planning measures and the usefulness of freely available medium resolution data in gaining a comprehensive understanding of the evolution of cities.
This text offers a critique of a certain development in political discourses on progress, namely the “decoupling” of notions of moral from notions of technological progress. This decoupling yields fatal social, economic and ecologic consequences in practice that ultimately amount to a virtual perversion of progress. The second part of the paper reflects upon the psychosocial drivers of this dynamic. I venture that the only motive that may explain why we reproduce this dynamic even as we increasingly suffer from its consequences is a compulsive avoidance of limitation, i.e. non-satisfaction of needs. Finally, I offer some tentative suggestions as to what a mature approach towards limitation would entail.
Based on a case study in northern Pakistan, this paper investigates the complex processes of change that have reshaped local farming systems there in recent decades. In Pakistan, agricultural policies emphasize intensification and productivity growth as overarching, nationwide goals. In an empirical investigation of changing farming practices in the mountain district of Nagar, guided by an assemblage-theory perspective on agricultural change, the paper questions this lopsided view. The case study reveals a significant shift from subsistence- to market-oriented crop production in recent decades, but also an emerging tendency among farmers to invest less time and effort in sophisticated and productivity-enhancing practices — in other words, a certain de-intensification of the latter. These processes may seem contradictory, but make sense for local households who adapt their farming strategies to a changing social, political, and economic context. Following political reforms and major road improvements, new livelihood opportunities, lifestyles, and ideals have emerged in the community and contributed to a significant shift away from farming aspirations, despite a general process of agricultural commercialization. The paper concludes that processes of agricultural development cannot be adequately addressed by the narrowly defined productivity goals of related policies in Pakistan, as for smallholder farmers the maximization of production is not necessarily a priority. Instead, more holistic approaches are needed that focus on safeguarding the agricultural resource base while also supporting the aspiration of local farming households to diversify their livelihoods.
Calls for a “sustainable bioeconomy” have recently begun to proliferate in academic and political circles as an answer to global challenges such as the rapidly increasing world population and changing environmental conditions due to climate change. To build economies that rely on various sources of biomass rather than on fossil-based resources, bioeconomy policies highlight a need to explore ways in which productivity in agriculture can be increased. While the focus on productivity growth has largely been inspired by technology optimism and modernisation thinking, the local knowledge of farmers and other rural stakeholders – as a means of contributing to socially and ecologically more sustainable bioeconomy pathways – has frequently been sidelined. This perspective article proposes and discusses a participatory approach to strategy formulation and evaluation in agricultural transformation and bioeconomy development that is based on the methodological toolbox MARISCO (Adaptive MAnagement of vulnerability and RISk at COnservation sites). By offering a means of developing a comprehensive knowledge map, bringing together both insights and perspectives from diverse local stakeholders, this approach enables a systemic evaluation of the social and ecological effects of intervention strategies on the ground. The article outlines the benefits – and challenges – of such a systemic and participatory approach and briefly sketches how the results can be utilised in more sustainable governance processes in the development of bioeconomy strategies. We conclude that our adapted MARISCO methodology offers a viable tool to make more visible the perspectives and knowledge of biomass producers for policymakers and to contribute to a much-needed discursive shift in bioeconomy debates towards more holistic and inclusive perspectives.
