RESUMO

Climate change and biodiversity loss trigger policies targeting and impacting local communities worldwide. However, research and policy implementation often fail to sufficiently consider community responses and to involve them. We present the results of a collective self-assessment exercise for eight case studies of communications with regard to climate change or biodiversity loss between project teams and local communities. We develop eight indicators of good stakeholder communication, reflecting the scope of Verran's (2002) concept of postcolonial moments as a communicative utopia. We demonstrate that applying our indicators can enhance communication and enable community responses. However, we discover a divergence between timing, complexity and (introspective) effort. Three cases qualify for postcolonial moments, but scrutinising power relations and genuine knowledge co-production remain rare. While we verify the potency of various instruments for deconstructing science, their sophistication cannot substitute trust building and epistemic/transdisciplinary awareness. Lastly, we consider that reforming inadequate funding policies helps improving the work in and with local communities.

RESUMO

Management of protected areas must adapt to climate impacts, and prepare for ongoing ecological transformation. Future-Proofing Conservation is a dialogue-based, multi-stakeholder learning process that supports conservation managers to consider the implications of climate change for governance and management. It takes participants through a series of conceptual transitions to identify new management options that are robust to a range of possible biophysical futures, and steps that they can take now to prepare for ecological transformation. We outline the Future-Proofing Conservation process, and demonstrate its application in a pilot programme in Colombia. This process can be applied and adapted to a wide range of climate adaptation contexts, to support practitioners in developing positive ways forward for management and decision-making. By acknowledging scientific uncertainty, considering social values, and rethinking the rules that shape conservation governance, participants can identify new strategies towards "future-oriented conservation" over the long term.

RESUMO

We examine issues to consider when reframing conservation science and practice in the context of global change. New framings of the links between ecosystems and society are emerging that are changing peoples' values and expectations of nature, resulting in plural perspectives on conservation. Reframing conservation for global change can thus be regarded as a stage in the evolving relationship between people and nature rather than some recent trend. New models of how conservation links with transformative adaptation include how decision contexts for conservation can be reframed and integrated with an adaptation pathways approach to create new options for global-change-ready conservation. New relationships for conservation science and governance include coproduction of knowledge that supports social learning. New processes for implementing adaptation for conservation outcomes include deliberate practices used to develop new strategies, shift world views, work with conflict, address power and intergenerational equity in decisions, and build consciousness and creativity that empower agents to act. We argue that reframing conservation for global change requires scientists and practitioners to implement approaches unconstrained by discipline and sectoral boundaries, geopolitical polarities, or technical problematization. We consider a stronger focus on inclusive creation of knowledge and the interaction of this knowledge with societal values and rules is likely to result in conservation science and practice that meets the challenges of a postnormal world.

RESUMO

Adaptation services are the ecosystem processes and services that benefit people by increasing their ability to adapt to change. Benefits may accrue from existing but newly used services where ecosystems persist or from novel services supplied following ecosystem transformation. Ecosystem properties that enable persistence or transformation are important adaptation services because they support future options. The adaptation services approach can be applied to decisions on trade-offs between currently valued services and benefits from maintaining future options. For example, ecosystem functions and services of floodplains depend on river flows. In those regions of the world where climate change projections are for hotter, drier conditions, floods will be less frequent and floodplains will either persist, though with modified structure and function, or transform to terrestrial (flood-independent) ecosystems. Many currently valued ecosystem services will reduce in supply or become unavailable, but new options are provided by adaptation services. We present a case study from the Murray-Darling Basin, Australia, for operationalizing the adaptation services concept for floodplains and wetlands. We found large changes in flow and flood regimes are likely under a scenario of +1.6°C by 2030, even with additional water restored to rivers under the proposed Murray-Darling Basin Plan. We predict major changes to floodplain ecosystems, including contraction of riparian forests and woodlands and expansion of terrestrial, drought-tolerant vegetation communities. Examples of adaptation services under this scenario include substitution of irrigated agriculture with dryland cropping and floodplain grazing; mitigation of damage from rarer, extreme floods; and increased tourism, recreational, and cultural values derived from fewer, smaller wetlands that can be maintained with environmental flows. Management for adaptation services will require decisions on where intervention can enable ecosystem persistence and where transformation is inevitable. New ways of managing water that include consideration of the increasing importance of adaptation services requires major changes to decision-making that better account for landscape heterogeneity and large-scale change rather than attempting to maintain ecosystems in fixed states.

RESUMO

Ecosystem services are typically valued for their immediate material or cultural benefits to human wellbeing, supported by regulating and supporting services. Under climate change, with more frequent stresses and novel shocks, 'climate adaptation services', are defined as the benefits to people from increased social ability to respond to change, provided by the capability of ecosystems to moderate and adapt to climate change and variability. They broaden the ecosystem services framework to assist decision makers in planning for an uncertain future with new choices and options. We present a generic framework for operationalising the adaptation services concept. Four steps guide the identification of intrinsic ecological mechanisms that facilitate the maintenance and emergence of ecosystem services during periods of change, and so materialise as adaptation services. We applied this framework for four contrasted Australian ecosystems. Comparative analyses enabled by the operational framework suggest that adaptation services that emerge during trajectories of ecological change are supported by common mechanisms: vegetation structural diversity, the role of keystone species or functional groups, response diversity and landscape connectivity, which underpin the persistence of function and the reassembly of ecological communities under severe climate change and variability. Such understanding should guide ecosystem management towards adaptation planning.

RESUMO

BACKGROUND: Education of health professionals is a key element of the wider strategy to increase society's physical activity levels. To date, no study has directly assessed UK medical students' knowledge of physical activity guidelines or their ability/willingness to prescribe exercise. METHODS: A questionnaire survey of final year medical students in Scottish Universities was conducted prior to a presentation on the current UK guidelines. RESULTS: Completed questionnaires (n=177) represented 37% of the final year cohorts. Physical inactivity was incorrectly perceived to be the least important risk factor to global mortality. 40% stated they were aware of current guidelines, but in a forced choice, 68% were able to correctly identify them for adults. In comparison, 97% correctly identified the UK's alcohol guidelines. 52% stated they felt adequately trained to give physical activity advice to the general public. CONCLUSIONS: The medical students in this study underestimated the risk of physical inactivity, and did not know the physical activity guidelines as well as other health promotion guidelines. A large proportion remained unconfident about giving physical activity advice. Improved education of this group is required.

RESUMO

OBJECTIVES: Foundation Year Ones (FY1s) are the most junior doctors in the UK who are often required to prescribe intravenous fluid to patients not under their regular care, during on-call or out-of-hours ward cover. This study aimed to investigate FY1s' practice and decision-making process of intravenous fluid prescribing to these patients. DESIGN: Questionnaire survey. SETTING: Survey on Practices during on-calls and out-of-hours ward covers. PARTICIPANTS: FY1s of five National Health Service (NHS) hospitals in England and Scotland. RESULTS: All 149 FY1s responded to survey. Eighty-six percent have been taught intravenous fluid prescribing during medical school, compared with only 48% in FY1 induction. More than half always/often checked the patient's urea and electrolytes (U&Es) (72%), read the fluid balance (58%) and observation charts (80%), discussed the case with nursing staff (75%), enquired about oral status (82%), identified the main diagnosis/operation (75%) and indication for intravenous fluid (72%) of the patient when prescribing intravenous fluid. However, less than half often/always read the medical notes (43%) or performed clinical examinations on patients (16%). Most FY1s (94%) always/often checked patient's U&Es when prescribing potassium. CONCLUSIONS: The questionnaire study demonstrated variations among FY1s in the practice and decision-making process of intravenous fluid prescribing to patients unknown to them, during on-calls or out-of-hours ward covers. Such variations in practice should be addressed especially by medical and foundation schools, and NHS hospitals to improve patient care.

RESUMO

The strong trends in climate change already evident, the likelihood of further changes occurring, and the increasing scale of potential climate impacts give urgency to addressing agricultural adaptation more coherently. There are many potential adaptation options available for marginal change of existing agricultural systems, often variations of existing climate risk management. We show that implementation of these options is likely to have substantial benefits under moderate climate change for some cropping systems. However, there are limits to their effectiveness under more severe climate changes. Hence, more systemic changes in resource allocation need to be considered, such as targeted diversification of production systems and livelihoods. We argue that achieving increased adaptation action will necessitate integration of climate change-related issues with other risk factors, such as climate variability and market risk, and with other policy domains, such as sustainable development. Dealing with the many barriers to effective adaptation will require a comprehensive and dynamic policy approach covering a range of scales and issues, for example, from the understanding by farmers of change in risk profiles to the establishment of efficient markets that facilitate response strategies. Science, too, has to adapt. Multidisciplinary problems require multidisciplinary solutions, i.e., a focus on integrated rather than disciplinary science and a strengthening of the interface with decision makers. A crucial component of this approach is the implementation of adaptation assessment frameworks that are relevant, robust, and easily operated by all stakeholders, practitioners, policymakers, and scientists.

RESUMO

Australia is faced with large-scale dryland salinization problems, largely as a consequence of the clearing of native vegetation for cropland and grassland. We estimate the change in continental water vapour flow (evapotranspiration) of Australia during the past 200 years. During this period there has been a substantial decrease in woody vegetation and a corresponding increase in croplands and grasslands. The shift in land use has caused a ca. 10% decrease in water vapour flows from the continent. This reduction corresponds to an annual freshwater flow of almost 340 km(3). The society-induced alteration of freshwater flows is estimated at more than 15 times the volume of run-off freshwater that is diverted and actively managed in the Australian society. These substantial water vapour flow alterations were previously not addressed in water management but are now causing serious impacts on the Australian society and local economies. Global and continental freshwater assessments and policy often neglects the interplay between freshwater flows and landscape dynamics. Freshwater issues on both regional and global levels must be rethought and the interplay between terrestrial ecosystems and freshwater better incorporated in freshwater and ecosystem management.
