- Traditional impact models combine exposure in the form of scenarios and sensitivity in the form of parameters, providing potential impacts of global change as model outputs. However, adaptive capacity is rarely addressed in these models. This paper presents the first spatially explicit scenario-driven model of adaptive capacity, which can be combined with impact models to support quantitative vulnerability assessment. The adaptive capacity model is based on twelve socio-economic indicators, each of which is projected into the future using four global environmental change scenarios, and then aggregated into an adaptive capacity index in a stepwise approach using fuzzy set theory. The adaptive capacity model provides insight into broad patterns of adaptive capacity across Europe, the relative importance of the various determinants of adaptive capacity, and how adaptive capacity changes over time under different social and economic assumptions. As such it provides a context for the implementation of specific adaptation measures. This could improve integrated assessment models and could be extended to other regions. However, there is a clear need for a better theoretical understanding of the adaptive capacity concept, and its relationship to the actual implementation of adaptation measures. This requires more empirical research and coordinated meta-analyses across regions and economic sectors, and the development of bottom-up modelling techniques that can incorporate human decision making.

- A potential change in climate and temperature could strongly affect weather-related crop losses. Using wastelands to grow crops in controlled greenhouse environments could improve global food security and preserve ecosystems. However, the impact of climate change on additional energy and water requirements of greenhousehorticulture food production is still unknown. Using a greenhouse simulator for four locations (The Netherlands, Spain, Saudi Arabia and Namibia), we show that a rise in outdoor temperatures can be counterbalanced with a more intensive water-based cooling. Between 6.9% and 17.9%, more water is required in the worst-case scenario in the year 2100, while the yield quantity decreases by 3%-6% due to slightly deteriorating growth conditions within the greenhouse. Since cooling systems consume up to 90% of the total water use in desert greenhouses, saltwater cooling could play an essential role in increasing the efficiency and sustainability of greenhouse horticulture systems in arid regions. In this study, we investigate the economic and technical feasibility of such greenhouse systems on a larger scale and show the massive potential of these systems. The developed scenarios demonstrate considerable climate resilience, enabling the cultivation of fresh vegetables in arid and infertile regions both presently and in the future.

Tidskriftsartikel (refereegranskat)abstract
- In nearly all domains of Global Change Research (GCR), the role of humans is a key factor as a driving force, a subject of impacts, or an agent in mitigating impacts and adapting to change. While advances have been made in the conceptualisation and practice of interdisciplinary Global Change Research in fields such as climate change and sustainability, approaches have tended to frame interdisciplinarity as actor-led, rather than understanding that complex problems which cut across disciplines may require new epistemological frameworks and methodological practices that exceed any one discipline. GCR studies must involve from their outset the social, human, natural and technical sciences in creating the spaces of interdisciplinarity, its terms of reference and forms of articulation. We propose a framework for funding excellence in interdisciplinary studies, named the Radically Inter- and Trans-disciplinary Environments (RITE) framework. RITE includes the need for a realignment of funding strategies to ensure that national and international research bodies and programmes road-map their respective strengths and identified areas for radical interdisciplinary research; then ensure that these areas can and are appropriately funded and staffed by talented individuals who want to apply their creative scientific talents to broader issues than their own field in the long term, rather than on limited scope (5 year and less) research projects. While our references are mostly to Europe, recommendations may be applicable elsewhere. (C) 2012 Elsevier Ltd. All rights reserved.
