Current practices and user expectations

IAISE Policy Brief No. 1 on "Impact Assessment Systems and Tools in Europe: Current Practices and User Expectations" has just been published. This policy brief presents the key findings on the most comprehensive survey yet conducted of user needs and expectations with regard to Impact Assessment (IA) systems and tools in 17 European countries. The survey was carried out by researchers from the LIAISE Network of Excellence, who collected data through documentary analysis and interviews with 130 people who steer IA at a strategic level, i.e. those people who champion, oversee, guide, audit or write guidance for IA processes. A more detailed description of the survey’s results can be found in the LIAISE Innovation Report No. 2 (January 2011)

Agricultural biomass as provisioning ecosystem service: quantification of energy flows

Agro-ecosystems supply provisioning, regulating and cultural services to human society. This study focuses on the agro-ecosystem provisioning services regarding the production of agricultural biomass. These services strongly respond to the socio-economic demands of human beings, and are characterised by an injection of energy in the ecosystems production cycle which is often exceeding the ecological capacity of the ecosystem, i.e. the overall ability of the ecosystem to produce goods and services linked to its bio-physical structure and processes that take place during the agricultural production. Agricultural production is identified as ecosystem service in widely recognised ecosystem service frameworks, but currently there is no clear agreement within the scientific and policy communities on how the ecological-socio-economic flow linked to this provisioning service should be assessed, beyond a mere accounting of yields. This study attempts to provide a new insight to this issue by proposing an approach based on the energy budget, which takes into consideration the energy needed by the ecosystem to supply the service. The approach is based on the concepts of Energy Return on Investment (EROI) and Net Energy Balance (NEB), and considers different bio-physical structures and processes of agro-ecosystems. The work is structured in three parts: the first aims at estimating inputs (machinery, seeds, fertilizers, irrigation, labour) in energy terms; the second at estimating biomass output in energy terms; the third to compare actual agricultural production with three reference scenarios encompassing a range of human input (no input – low input – high input scenarios). Results show that in general terms cereal and grassland systems have the largest energy gains (both in terms of EROI and NEB). Such systems are characterised by a lower economic value of their output compared to other producing systems such as fruits, which have lower energy gains but a higher embodied energy, which is recognized in the market as valuable. Comparison of actual production systems with the high input scenario confirms that current production in Europe is already highly intensive, and that increasing the energy input would not improve the efficiency of the conversion of such additional energy into biomass. Overall, the proposed approach seems a useful tool to identify which are the factors in the agricultural production process that could be modified to improve the energy efficiency in agricultural systems and the sustainability of their production. This study can be considered as a first step in the assessment of the total energy balance of the agro-ecosystem. In fact it deals with the quantification of energy regarding human inputs and the corresponding output and further analysis should address crucial issues such as the quality of the energy and the embodied energy in the plant production, which will help to understand the full complexity of the agro-ecosystemJRC.H.4-Monitoring Agricultural Resource

Mapping and assessment of ecosystems and their services. Urban ecosystems

Action 5 of the EU Biodiversity Strategy to 2020 requires member states to Map and Assess the state of Ecosystems and their Services (MAES). This report provides guidance for mapping and assessment of urban ecosystems. The MAES urban pilot is a collaboration between the European Commission, the European Environment Agency, volunteering Member States and cities, and stakeholders. Its ultimate goal is to deliver a knowledge base for policy and management of urban ecosystems by analysing urban green infrastructure, condition of urban ecosystems and ecosystem services. This report presents guidance for mapping urban ecosystems and includes an indicator framework to assess the condition of urban ecosystems and urban ecosystem services. The scientific framework of mapping and assessment is designed to support in particular urban planning policy and policy on green infrastructure at urban, metropolitan and regional scales. The results are based on the following different sources of information: a literature survey of 54 scientific articles, an online-survey (on urban ecosystems, related policies and planning instruments and with participation of 42 cities), ten case studies (Portugal: Cascais, Oeiras, Lisbon; Italy: Padua, Trento, Rome; The Netherlands: Utrecht; Poland: Poznań; Spain: Barcelona; Norway: Oslo), and a two-day expert workshop. The case studies constituted the core of the MAES urban pilot. They provided real examples and applications of how mapping and assessment can be organized to support policy; on top, they provided the necessary expertise to select a set of final indicators for condition and ecosystem services. Urban ecosystems or cities are defined here as socio-ecological systems which are composed of green infrastructure and built infrastructure. Urban green infrastructure (GI) is understood in this report as the multi-functional network of urban green spaces situated within the boundary of the urban ecosystem. Urban green spaces are the structural components of urban GI. This study has shown that there is a large scope for urban ecosystem assessments. Firstly, urban policies increasingly use urban green infrastructure and nature-based solutions in their planning process. Secondly, an increasing amount of data at multiple spatial scales is becoming available to support these policies, to provide a baseline, and to compare or benchmark cities with respect to the extent and management of the urban ecosystem. Concrete examples are given on how to delineate urban ecosystems, how to choose an appropriate spatial scale, and how to map urban ecosystems based on a combination of national or European datasets (including Urban Atlas) and locally collected information (e.g., location of trees). Also examples of typologies for urban green spaces are presented. This report presents an indicator framework which is composed of indicators to assess for urban ecosystem condition and for urban ecosystem services. These are the result of a rigorous selection process and ensure consistent mapping and assessment across Europe. The MAES urban pilot will continue with work on the interface between research and policy. The framework presented in this report needs to be tested and validated across Europe, e.g. on its applicability at city scale, on how far the methodology for measuring ecosystem condition and ecosystem service delivery in urban areas can be used to assess urban green infrastructure and nature-based solutions

An aggregation framework to link indicators associated with multifunctional land use to the stakeholder evaluation of policy options

In the last decade efforts have been carried out by the scientific community aimed at building integrated frameworks to support the decision-making process when sustainability issues are addressed. This paper proposes a further advancement in integrated assessment procedures by setting up an operational multi-scale and transparent framework, which comprises the assessment of European regions in terms of sustainability, and the identification of the impact that policy options might have on the sustainability of these regions. The framework is designed for use in ex ante sustainability impact assessment of policy scenarios on multifunctionality of land use and integrates economic, environmental and social issues across a variety of sectors (agriculture, forestry, transport, tourism and energy). The proposed method provides a conceptual framework applicable at different scales (European, regional), and takes into account the great variability of European regions. The described methodology is based on linear additive models to weight and aggregate selected indicators to a set of land use functions identified to describe the goods and services provided by the different land uses that summarise the most relevant economic, environmental and social issues of a region. The framework is designed to allow the evaluation of impacts at an international scale (e.g. the European Union), or on selected regions. The aggregation framework can be used to evaluate the impact that policy options have on the sustainability of multifunctional land use systems with competing demands. A conceptual envelope, called the “trade-off evaluation space”, delineates all possible developments in the functions of the land. The sustainability limits identify the subset of ‘acceptable’ policy options within the trade-off evaluation space, so that the distance of each land use function from sustainability limits can be estimated and trade-offs between the different functions of the multifunctional land use system can be identified. The proposed methodology is adaptable to different contexts: if the assumption is taken that all land use functions are equally weighted the framework can be used to analyse policy cases and take decisions on policy options at the European or regional level. However, at the local-scale the framework can also be applied through a participatory approach and the distribution of weights can be rediscussed with local stakeholders. In both cases the proposed system can be used as a tool for discussion among all interested parties

Semi-natural vegetation in agricultural land: European map and links to ecosystem service supply

Patches of semi-natural vegetation, encompassing both woody vegetation and grassland, located within larger areas of agricultural land, are acknowledged to play an important role in biodiversity conservation and ecosystem service supply. In spite of its relevance, semi-natural vegetation in agricultural land (SENAGRI) has never been mapped at the EU spatial extent. To recover from this information lack, the original contribution of this paper is twofold. First, it delivers the first 1 km resolution continuous map of abundance of SENAGRI features at the EU scale. Second, it provides an EU region-based assessment of the correlation between the SENAGRI map and existing maps of ecosystem service supplies. The proposed mapping system adopts a convergence-of-evidence approach, whose inputs are multi-resolution geospatial information/data sources, like the 25 m resolution satellite Image 2000/Image 2006 mosaics, to be mapped by the fully automatic Spectral Rule-based preliminary Classifier (SRC), and several ancillary classification maps, like the 1 ha-resolution CORINE Land Cover (CLC) 2006 map and the 25 m resolution European Forest 2006 map. Validation of the SENAGRI output map with the Land Use and land Cover Area frame Sampling (LUCAS) 2006 reference data set reveals that the SENAGRI map accuracy is superior to those of the individual classification maps adopted as input. A region-specific analysis at the EU scale shows that: (i) correlation between SENAGRI abundance and regulating ecosystem services is significant (R2 = 0.67) and (ii) almost no correlation is found between SENAGRI abundance and provisioning ecosystem services. Finally, agricultural land in EU regions is parameterized by SENAGRI abundance, provisioning and regulating ecosystem services supply data. These EU region-specific values reveal that, within the Common Agricultural Policy (CAP), a portfolio of agro-environmental schemes is recommended to ensure agro-ecosystem sustainability, in compliance with the EU Strategy for Biodiversity to 2020 and the targets of the CAP post-2013.JRC.H.4-Monitoring Agricultural Resource

Mainstreaming ecosystem services into EU policy

This paper presents a synthesis of the PRESS initiative (PEER7 Research on Ecosystem Services). In support of the EU Biodiversity Strategy to 2020, this initiative demonstrated a multi-scale mapping and assessment approach of ecosystem services using three case studies. The water purification case studied the impacts of agricultural and water policy scenarios on the capacity of ecosystems to purify water. The conclusion was that greening the subsidies to farmers in Europe would improve water quality and increase the benefits to society as measured via monetary valuation. Yet, scenario based nitrogen reduction levels differed among the different scales (EU and basin scale) suggesting that the assessment of policy measures is scale-dependent, which, in turn, justifies a multi-scale mapping and assessment approach. The recreation case presented evidence that millions of people visited forests several times per year and they expressed their willingness to pay to continue doing so. The visitor statistics that were used in this study suggested that the Recreation Opportunity Spectrum approach is a useful method to identify areas in terms of their accessibility and potential to provide recreation services. Finally, we demonstrated that the coverage and resolution of current datasets are already sufficient to map the potential of ecosystems to provide pollination services. Further research should contribute to better ecological observations of key pollinator species to include important drivers of pollinator abundance in modelling and mapping approaches

GEOSPECS - European perspectives on Specific Types of Territories

Regions with specific territorial features have received increasing attention in recent years, most notably in article 174 of the Treaty on the Functioning of the European Union (TFEU) and the Green Paper on Territorial Cohesion. These key policy documents identify certain territories – cross-border, island, mountain, Outermost and sparsely populated regions – in two ways: as having particular challenges, and as having particular assets, many of benefit to Europe as a whole. Two other types of such ‘geographic specificities' have also been recognised: coastal areas and inner peripheries. While there have been a number of studies of groups of these areas, or individual types of territories (e.g., coasts, mountains) at the European scale, GEOSPECS is the first comprehensive study of all of these particular types of territories

Operationalising ecosystem services: advancing knowledge on natural and cultural capital

contact with nature induces many different feelings, both positive and negative. on the negative side, people can suffer from allergies from flowering plants, many insect species can cause physical harm or spread disease (lyytimäki and sipilä, 2009) and some parks in cities can hide social dangers (Bixler and Floyd, 1997). alternatively, when people are asked to close their eyes and think of something positive, they often see meadows and oceans, trees and dolphins. connections between forests and timber production, as well as fish populations and food security, are widely understood. However, few people know, for example, that having close contact with the natural environment raises your immunological tolerance against inflammatory diseases such as allergies and cancer (Hanski et al., 2012). in wider society, the links between the structures and processes of nature, and between natural capital and the ecosystem services essential for human well-being, are often poorly understood. the structures and processes linked with natural capital can be explained in many ways. in our work, ecosystem services and their operationalisation are the bridge from natural capital to human well-being. We base our conclusions on research carried out in the Eu-funded opennEss project (1), and suggest a five-step path for better understanding of how natural capital and the ecosystem services that flow from it are important to human well-being. Finally, we emphasise the role of natural capital in finding innovative solutions to environmental problems and societal challenges in the form of nature-based solutions (nBs), which build on, and contribute to, the transition towards a bio- and circular economy. understanding natural capital and ecosystem services provides the basis for thriving cultural capital in its broad meaning, by strengthening society’s ability to make wise decisions concerning our relationship with natural capital.publishedVersio
