Publicación The CAP 2020: interpretating the Communication of the European Commission, COM (2010) 672 from 18.11.2010(2011-10-31) Massot Martí, Albert[EN] The purpose of this paper is to analyse the content of the European Commission’s Communication of 18th November 2010 on the future of the CAP. It discusses the key issues of interest that will be tackled during the CAP reform process and it also provides some suggestions in order to support the debate before the presentation of the legislative proposals from the Commission in 2011.Publicación The economics of agrobiodiversity conservation for food security under climate change(2011-10-31) Pascual, Unai; Narloch, Ulf; Nordhagen, Stella; Drucker, Adam G.[EN] Subsistence-based and natural resource-dependent societies are especially vulnerable to climate change. In such contexts, food security needs to be strengthened by investing in the adaptability of food systems. This paper looks into the role of agrobiodiversity conservation for food security in the face of climate change. It identifies agrobiodiversity as a key public good that delivers necessary services for human wellbeing. We argue that the public values provided by agrobiodiversity conservation need to be demonstrated and captured. We offer an economic perspective of this challenge and highlight ways of capturing at least a subset of the public values of agrobiodiversity to help adapt to and reduce the vulnerability of subsistence based economies to climate change.Publicación The economic assessment of changes in ecosystem services: an application of the CGE methodology(2011-10-31) Bosello, Francesco; Eboli, Fabio; Parrado, Ramiro; Nunes, Paolo A.L.D.; Ding, Helen; Rosa, Renato; European Investment Bank[EN] The present study integrates Computable General Equilibrium (CGE) modelling with biodiversity services, proposing a possible methodology for assessing climate-change impacts on ecosystems. The assessment focuses on climate change impacts on carbon sequestration services provided by European forest, cropland and grassland ecosystems and on provisioning services, but provided by forest and cropland ecosystems only. To do this via a CGE model it is necessary to identify first the role that these ecosystem services play in marketable transactions; then how climate change can impact these services; and finally how the economic system reacts to those changes by adjusting demand and supply across sectors, domestically and internationally.Publicación Contributions towards climate change vulnerability and resilience from institutional economics(2011-10-31) Díaz Simal, Pedro; Torres Ortega, Saúl[EN] This paper analyzes the various contributions made in the economic literature that in fluence climate change vulnerability. We try to create conceptual order and transparence in the contributions identifying the assumptions and constraints that each school has introduced into academic debate and practical application. We analyze the conceptual framework that articulates the debate, review the theoretical approaches developed in the literature identifying the object of analysis and the basics of each theory, so that the real model implications are established in each case study. From this scheme we derive a clarifying proposal for organizing theoretical discourse. We specifically focus on the theoretical assumptions underlying each model. We conclude with some criteria for choosing the right models in each case and a general guideline for future research.Publicación Contributions from economics of adaptation to decision making: An example for the Autonomous Community of the Basque Country(2011-10-31) Galarraga, Ibon; Osés, Nuria; Markandya, Anil; Chiabai, Aline; Khatun, Kaysara[EN] As a consequence of Climate Change sea level rise as well as a change in the intensity and propensity of rain are expected in the Basque Country. Valuing the costs and benefits of adapting to these changes becomes an important piece of information for the planning process. This paper develops two methodological frameworks. The first one devoted to estimating the economic impacts to urban areas of an increase in the risk of flooding. The values estimated for the Nervión river in the city of Amurrio (Álava) indicate that the average expected damage will increase in 15 per cent as a consequence of CC (from €56,097 to €64,451). For an extreme episode the total loss could increase to €20 million. The second framework is oriented towards the valuation of the damages as a consequence of sea level rise for 2100. The values in this case range from €87 to €231 million, that is, between €0.87 and €2.3 million per hectare.Publicación Adaptation approaches to climate change in China: an operational framework(2011-10-31) Jiahua, Pan; Yan, Zheng; Markandya, Anil[EN] Climate change poses great risks for China, which makes adaptation an essential response. However, adaptation planning and implementation are still at a preliminary stage with respect to the theoretical framework and methodology. This article focuses on the status, problems and basic needs as regards adaptation to climate change, and outlines the operational framework that the government is seeking to pursue for China’s adapting to climate change. The conclusion is that, to satisfy the basic needs of development, it is necessary to clarify development-oriented and incremental adaptation. Furthermore measures to enhance adaptive capacity can be classified as infrastructure-based, technology-based and institutional. Lastly the authors stress the importance of appraising adaptation actions and measures from an economic perspective.Publicación Scientific instruments for climate change adaptation: estimating and optimizing the efficiency of ecosystem service provision(2011-10-31) Villa, Ferdinando; Bagstad, Ken; Johnson, Gary; Voigt, Brian; National Science Foundation, EEUU; UN Environment Programme World Conservation Monitoring Centre[EN] Adaptation to the consequences of climate change can depend on efficient use of ecosys tem services (ES), i.e. a better use of natural services through management of the way in which they are delivered to society. While much discussion focuses on reducing consumption and increasing production of services, a lack of scientific instruments has so far prevented other mechanisms to improve ecosystem services efficiency from being addressed systematically as an adaptation strategy. This paper describes new methodologies for assessing ecosystem services and quantifying their values to humans, highlighting the role of ecosystem service flow analysis in optimizing the efficiency of ES provision.Publicación Impacts and adaptive capacity as drivers for prioritising agricultural adaptation to climate change in Europe(2011-10-31) Schlickenrieder, Jeremy; Quiroga, Sonia; Diz, Agustín; Iglesias, Ana; European Commission[EN] In the face of likely climate change impacts policy makers at different spatial scales need access to assessment tools that enable informed policy instruments to be designed. Recent scientific advances have facilitated the development of improved climate projections, but it remains to be seen whether these are translated into effective adaptation strategies. This paper uses existing databases on climate impacts on European agriculture and combines them with an assessment of adaptive capacity to develop an interdisciplinary approach for prioritising policies. It proposes a method for identifying relevant policies for different EU countries that are representative of various agroclimatic zones. Our analysis presents a framework for integrating current knowledge of future climate impacts with an understanding of the underlying socio-economic, agricultural and environmental traits that determine a region’s capacity for adapting to climate change.Publicación Climate change and food security to 2030: a global economy-wide perspective(2011-10-31) Valenzuela, Ernesto; Anderson, Kym[EN] The effects of climate change on agriculture raise major food security concerns. We use a global economy-wide model to assess the effects on farm product prices of expected yield changes. Also modelled is an expected adverse effect of higher temperatures and humidity in the tropics on the productivity of unskilled workers in developing countries. Given the degrees of uncertainty about plausible effects of climate change, our modelling accounts for a range of yield productivity and labor shocks. The results entail consequences for international agricultural prices, national food consumption, self sufficiency, net farm income and economic welfare.Publicación Costs of adaptation to climate change impacts on fresh-water systems: existing estimates and research gaps(2011-10-31) Martín-Ortega, Julia[EN] Information on the cost of adaptation in freshwater systems is necessary to better design strategies to face climate change and water management. We look at the existing estimates with the aim of identifying research gaps. Our analysis shows that case study-specific literature is scarce, fragmented, and not always methodologically transparent. At the same time, most existing global assessments are likely to represent underestimates and rely heavily on each other. We conclude that a clear conceptual framework is still missing. Remaining research gaps include addressing inter-sector linkages and estimations of other than only direct costs, in addition to addressing the issues of ‘adaptation deficit’ and ‘residual damage’.
