Impacts and adaptive capacity as drivers for prioritizing agricultural adaptation to climate change in Europe

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.

An economic modelling approach for vulnerability assesment in irrigation farms in Spain

In the last years, vulnerability assessment has emerged as a need for policy making instead of being a pure academic exercise (Hinkel, 2010). In the current context of changing climate, increasing water scarcity threatens economic activities in many arid or semi-arid regions of the World. Climate change (CC) science and policy debates have traditionally focused on CC mitigation and impact assessment (Krysanova et al., 2010). However, even if mitigation policies are successfully enforced some climate change is still expected. Then, adaptation is strongly necessary and, for that, improved knowledge on vulnerability and adaptive capacity is required.

Assessing forest response-type diversity to natural disturbances in Peninsular Spain and the Balearic Islands = Evaluación de la diversidad de tipos de respuesta a perturbaciones naturales en la España peninsular e Islas Baleares

Disturbances shape forest ecosystems by influencing their composition, structure, and processes. In the Mediterranean Basin, changes in the disturbance regimes have been predicted to occur in the next future with a higher occurrence of extreme events of drought, wildfire, and – to a lesser extent – windstorm. Woody species are the main elements defining the structure and functioning of forest ecosystems. Recently, response-type diversity has been pointed out as an appropriate indicator of ecosystems resilience. For this, we have elaborated a complete response-trait database for the tree and shrubby species considered in the Third Spanish National Forest Inventory (3SNFI). In the database, the presence or absence of nine response traits associated to drought, fire, and wind were assigned to each species. The database reflected the lack of information about some important traits (in particular for shrubby species) and allowed to determine those traits most widely distributed. The information contained in the database was then used to assess a relative index of forest resilience to these disturbances calculated from the abundance of response traits and the species redundancy for each plot of the 3SNFI; considering both tree and shrubby species. In general, few plots showed high values of the resilience index, probably because some traits were scarcely presented in the species and also because most plots presented very few species. The cartographic representation of the index showed low values for the stands located in mountainous ranges, which are mostly composed by species typical from central Europe. In the other side, Eucalyptus plantations in Galicia appeared as one thee the most resilient ecosystems, due to its higher adaptive capacity to persist after the occurrence of drought, fire, and windstorm events. We conclude that the response traits database can constitute a useful tool for forest management and planning and for future research to enhance the forest resilience.

Viticultura y Cambio Climático en España: Vulnerabilidad en las distintas regiones y estrategias de adaptación frente al desarrollo de nuevas políticas

El presente trabajo realiza un análisis de la vulnerabilidad de la viticultura en España ante el Cambio Climático que contribuya a la mejora de la capacidad de respuesta del sector vitivinícola a la hora de afrontar los retos de la globalización. Para ello se analiza el impacto que puede tener el Cambio Climático en primer lugar sobre determinados riesgos ocasionados por eventos climáticos adversos relacionados con extremos climáticos y en segundo lugar, sobre los principales índices agro-climáticos definidos en el Sistema de Clasificación Climática Multicriterio Geoviticultura (MCGG), que permiten clasificar las zonas desde un punto de vista de su potencial climático. Para el estudio de las condiciones climáticas se han utilizado los escenarios de Cambio Climático regionalizados del proyecto ESCENA, desarrollados dentro del Plan Nacional de Adaptación al Cambio Climático (PNACC) con el fin de promover iniciativas de anticipación y respuesta al Cambio Climático hasta el año 2050. Como parte clave del estudio de la vulnerabilidad, en segundo lugar se miden las necesidades de adaptación para 56 Denominaciones de Origen Protegidas, definidas por los impactos y de acuerdo con un análisis de sensibilidad desarrollado en este trabajo. De este análisis se desprende que los esfuerzos de adaptación se deberían centrar en el mantenimiento de la calidad sobre todo para mejorar las condiciones en la época de maduración en los viñedos de la mitad norte, mientras que en las zonas de la mitad sur y del arco mediterráneo, además deberían buscar mantener la productividad en la viticultura. Los esfuerzos deberían ser más intensos en esta zona sur y también estarían sujetos a más limitaciones, ya que por ejemplo el riego, que podría llegar a ser casi obligatorio para mantener el cultivo, se enfrentaría a un contexto de mayor competencia y escasez de recursos hídricos. La capacidad de afrontar estas necesidades de adaptación determinará la vulnerabilidad del viñedo en cada zona en el futuro. Esta capacidad está definida por las propias necesidades y una serie de condicionantes sociales y de limitaciones legales, como las impuestas por las propias Denominaciones de Origen, o medioambientales, como la limitación del uso de agua. El desarrollo de estrategias que aseguren una utilización sostenible de los recursos hídricos, así como el apoyo de las Administraciones dentro de la nueva Política Agraria Común (PAC) pueden mejorar esta capacidad de adaptación y con ello disminuir la vulnerabilidad. ABSTRACT This paper analyzes the vulnerability of viticulture in Spain on Climate Change in order to improve the adaptive capacity of the wine sector to meet the diverse challenges of globalization. The risks to quality and quantity are explored by considering bioclimatic indices with specific emphasis on the Protected Designation of Origin areas that produce the premium winegrapes. The Indices selected represents risks caused by adverse climatic events related to climate extremes, and requirements of varieties and vintage quality in the case of those used in the Multicriteria Climatic Classification System. (MCCS). To study the climatic conditions, an ensemble of Regional Climate Models (RCMs) of ESCENA project, developed in the framework of the Spanish Plan for Regional Climate Change Scenarios (PNACC-2012) have been used As a key part of the study of vulnerability risks and opportunities are linked to adaptation needs across the Spanish territory. Adaptation efforts are calculated as proportional to the magnitude of change and according to a sensitivity analysis for 56 protected designations of origin. This analysis shows that adaptation efforts should focus on improving conditions in the ripening period to maintain quality in the vineyards of the northern half of Iberian Peninsula, while in areas of the southern half and in the Mediterranean basin, also should seek to maintain productivity of viticulture. Therefore, efforts should be more intense in the Southern and Eastern part, and may also be subject to other limitations, such as irrigation, which could become almost mandatory to keep growing, would face a context of increased competition and lack of resources water. The ability to meet these needs will determine the vulnerability of the vineyard in each region in the future. This capability is defined also by a number of social factors and legal limitations such as environmental regulations, limited water resources or those imposed by their own Designation of Origin. The development of strategies to ensure sustainable use of water resources and the support schemes in the new Common Agricultural Policy (CAP) can improve the resilience and thus reduce vulnerability.
