Commercial and small-scale farmers in South Africa are exposed to many challenges. Interviews with 44 farmers in the upper Thukela basin, KwaZulu-Natal, were conducted to identify common and specific challenges for the two groups and adaptive strategies for dealing with the effects of climate and other stressors. This work was conducted as part of a larger participatory project with local stakeholders to develop a local adaptation plan for coping with climate variability and change. Although many challenges related to exposure to climate variability and change, weak agricultural policies, limited governmental support, and theft were common to both farming communities, their adaptive capacities were vastly different. Small-scale farmers were more vulnerable due to difficulties to finance the high input costs of improved seed varieties and implements, limited access to knowledge and agricultural techniques for water and soil conservation and limited customs of long-term planning. In addition to temperature and drought-related challenges, small-scale farmers were concerned about soil erosion, water logging and livestock diseases, challenges for which the commercial farmers already had efficient adaptation strategies in place. The major obstacle hindering commercial farmers with future planning was the lack of clear directives from the government, for example, with regard to issuing of water licences and land reform. Enabling agricultural communities to procure sustainable livelihoods requires implementation of strategies that address the common and specific challenges and strengthen the adaptive capacity of both commercial and small-scale farmers. Identified ways forward include knowledge transfer within and across farming communities, clear governmental directives and targeted locally adapted finance programmes.  相似文献

This article aims to address the challenges of sustainable earth system governance from a multi-scale level perspective. The local to regional system level reviews findings from a social–ecological system approach of a mangrove ecosystem in North Brazil. Seven challenges (Glaser et al. in Mangrove dynamics and management in North Brazil. Ecological studies series. Springer, Berlin, pp 307–388, 2010) that could provide relevant knowledge to society were identified. Their respective justification and recommendations are presented here. Further, these “challenges from the field” are linked and discussed with those challenges on earth system level elaborated by the International Council for Science in 2010. There it was stressed that sustainability problems are increasingly caused by drivers from multiple spatial and institutional levels in a single global human–nature system. The comparison between the global and local to regional challenges shows that most of these are reappearing disregarding the level of analysis, indicating that there is a universal core of global change problems. However, there are gaps visible which hamper the effective connections across the different spatial levels. These pertain to the subjects of knowledge generation and stakeholder inclusion. The final section elaborates on these recognized gaps and their science–policy dimensions. The article closes with the identification of a number of factors which currently impede global sustainability efforts: shortcomings in inter- and transdisciplinary research practice, lack of consistent structures for earth system governance and shortcomings in dealing with upscaling challenges whilst remaining locally relevant. A blueprint for a globally focused but regionally informed social–ecological analysis framework remains to be worked out.  相似文献

The purpose of the research is to identify the critical challenges that are impeding the adoption of e-mobility in India. It also aims to give a roadmap how to address these challenges while taking into considerations concerns of all the relevant stakeholders. Based on an in-depth literature review, an exploratory research design is employed to delve deep into various aspects of e-mobility. This is followed by a three-phase Delphi technique to identify and rate the e-mobility challenges in the Indian context. The study successfully identifies four different categories of challenges and proposes integrative framework for e-mobility. Further, the research goes on to lay out the future roadmap for mass adoption of electric vehicles (EVs) in India. The research is novel in terms of presenting a holistic viewpoint on e-mobility in India. Its originality lies in identifying the major inhibitors obstructing EVs adoption in India and then suggesting the roadmap how to overcome these impediments for mass adoption of e-mobility.  相似文献

Structuring sustainability science   总被引:2,自引:2,他引:0  
It is urgent in science and society to address climate change and other sustainability challenges such as biodiversity loss, deforestation, depletion of marine fish stocks, global ill-health, land degradation, land use change and water scarcity. Sustainability science (SS) is an attempt to bridge the natural and social sciences for seeking creative solutions to these complex challenges. In this article, we propose a research agenda that advances the methodological and theoretical understanding of what SS can be, how it can be pursued and what it can contribute. The key focus is on knowledge structuring. For that purpose, we designed a generic research platform organised as a three-dimensional matrix comprising three components: core themes (scientific understanding, sustainability goals, sustainability pathways); cross-cutting critical and problem-solving approaches; and any combination of the sustainability challenges above. As an example, we insert four sustainability challenges into the matrix (biodiversity loss, climate change, land use changes, water scarcity). Based on the matrix with the four challenges, we discuss three issues for advancing theory and methodology in SS: how new synergies across natural and social sciences can be created; how integrated theories for understanding and responding to complex sustainability issues can be developed; and how theories and concepts in economics, gender studies, geography, political science and sociology can be applied in SS. The generic research platform serves to structure and create new knowledge in SS and is a tool for exploring any set of sustainability challenges. The combined critical and problem-solving approach is essential.  相似文献

Climate change is one of the risks that society faces today. Among other things, it has the potential to interfere with the water environment, and thus it can be a relevant factor in current work with river basin management plans (RBMPs) in Denmark. At the same time, climate change in theory has characteristics that can pose challenges, if included in such a planning process. In this article, it is investigated what the attitudes towards climate change are among actors in the planning process, and what the main drivers, barriers and challenges related to including climate change in the RBMPs are, compared to the theoretical challenges. The investigation consists of a document study of hearing responses, interviews, and a survey among Danish municipalities. The overall results are that there are many attitudes towards the inclusion of climate change as a factor in RBMPs and that this diversity theoretically can be a challenge in the planning process. The main theoretical and practical barriers and challenges in connection with inclusion of climate change in RBMPs relate to lacking knowledge and uncertainty.  相似文献

While methodological choices are critical for solution-oriented adaptation research, the current debate on these is underdeveloped and characterized by simple dichotomies such as bottom-up and top-down as well as vaguely defined concepts such as vulnerability. Adaptation challenges and approaches for addressing them are more diverse than these labels suggest. This paper addresses this deficit by developing a diagnostic framework that helps to identify approaches suitable for addressing a given adaptation challenge. The framework was developed out of the necessity to discuss diverse approaches from natural science, social science and practice in a set of adaptation case studies conducted within the European funded MEDIATION project. Based on these case studies complemented by the literature, we iteratively abstracted typical adaptation challenges researched, typical approaches taken, and empirical, theoretical and normative criteria applied for choosing a particular approach. Our results refine the methodological debate by distinguishing between the three general adaptation challenges of identifying adaptation needs, identifying adaptation measures and appraising adaptation options. Adaptation challenges are further classified according to private and public interest involved, individual or various types of collective action involved, data/model availability, decision-making time horizon, etc. For each type of challenge and approach, we give examples and discuss salient issues. Our results point to the opportunity to apply institutional and behavioural research to support the identification of measures and possibly avoiding barriers in practice. The diagnostic framework also serves as the basis for the forthcoming guidance for assessing vulnerability, impacts and adaptation to be published by the UNEP programme of research on climate change vulnerability, impacts and adaptation.  相似文献

This paper contributes to our understanding of the challenges faced when seeking to apply systemic, integration concepts in ‘arenas of practice’. It takes a critical look at the application of the systems-based SPICOSA Project in the region of the Oder (Szczecin) Lagoon, which forms the border between Germany and Poland. The paper highlights a range of place-based and temporal-based factors, which need careful consideration when adopting systems-based approaches to Integrated Coastal Zone Management and makes a series of recommendations for how such approaches might be approved. The experience within the study site was that challenges relating to scale, in one of its many facets, strongly influenced abilities to integrate within the systemic approach. Our view is that cross-scale issues and multi-level challenges can be thought of as one of the dominant factors controlling the successfulness of system approaches to managing complex environments.  相似文献

Sustainability science represents a fundamental shift in the nature of research on environmental problems, calling for specialists to expand beyond their disciplinary perspectives in order to cooperate together to understand and address systemic problems. This shift demands a corresponding shift in education in order to equip students with the skills, theories, and methods they need to address contemporary challenges. We argue that case studies are a productive pedagogical approach to teaching about sustainability and teaching for sustainability. Case-based approaches equip students to encounter complexity, manage uncertainty, and generate innovative strategies. In laying out of the pedagogical challenges inherent in sustainability education, we highlight opportunities and demands for environmental communication scholars to contribute to the emerging discipline of sustainability science.  相似文献
