Changes in the vegetation composition of hay meadows between 1993 and 2009 in the Picos de Europa and implications for nature conservation

The Picos de Europa are a range of predominantly Carboniferous Limestone and Sandstone mountains mainly in the Cantabrian region of northern Spain. The highest peaks are precipitous and reach 2600 m. There are complex gradients between Lusitanian, Alpine and Mediterranean environmental zones, as well as variable soil types. In combination with the long history of traditional agricultural management, a wide range of diverse habitats and species is present. The herb-rich hay meadows have long been recognised as having a high nature conservation value but, as elsewhere in European mountains, such grasslands are threatened by changing agricultural practices. Accordingly, in 1993, 92 quadrats were recorded using a restricted list of indicator species from stratified random samples. The authors repeated the sample in 2009. Changed land use had only occurred in approximately 3% of meadows, however, farmyard manure was no longer used, probably because of shortage of labour. Statistical analysis of the vegetation data showed a range of significant changes consistent with the increased use of slurry, as well as re-seeding of some fields. The grass swards had not only become denser, with fewer species present, but there was also a loss of sensitive indicators especially of calcareous conditions and open vegetation. By contrast, competitors had increased and the vegetation had become simpler, with the balance of vegetation types shifting to more nutrient rich conditions. These changes have mainly occurred in the more fertile meadows used for silage. The core of about 35% of herb-rich meadows, mainly cut for hay, has remained relatively stable but the results show that they are at risk if the current trend continues. If management practices that form the core of traditional agriculture are not maintained, one of the most important resources of herb-rich meadows in Europe will be lost

Thirty years of connectivity conservation planning : An assessment of factors influencing plan implementation

Connectivity conservation is an emergent approach to counteracting landscape fragmentation and enhancing resilience to climate change at local, national, and global scales. While policy that promotes connectivity is advancing, there has been no systematic, evidence-based study that assesses whether connectivity conservation plans (CCPs) resulted in conservation outcomes, and identifies specific plan attributes that may favor successful implementation. To fill this gap, we gathered 263 terrestrial CCPs from around the world, characterized attributes of 109 plans by surveying plan authors, and conducted semi-structured interviews with authors and implementers of 77 CCPs. The production of CCPs started around 1990 and has increased markedly in all parts of the world, most notably in the United States (led by NGOs and a few states, with little federal involvement), Europe (led by the EU and national policies and implemented at local levels), and the Republic of South Africa (where national legislation mandates each municipality to map corridors and zone all land by 2020). All of the 109 plans that we examined in detail were followed by implementation actions such as crossing structures, ecological restoration, land purchases or easements, recognition of corridors through zoning or government designation, and public engagement. Interviewees emphasized the importance of initial buy-in from key government stakeholders, stakeholder involvement beyond initial buy-in, minimizing staff turnover, and transparent and repeatable procedures. Our quantitative and qualitative analyses similarly suggested that implementation of a CCP was enhanced by enduring partnerships among stakeholders, continuity of leadership, specific recommendations in the CCP using tools appropriately selected from a large toolbox, the existence of enabling legislation and policy, a transparent and repeatable scientific approach, adequate funding, and public outreach.</p

Competitiveness as an Indicator of Sustainable Development of Tourism: Applying Destination Competitiveness Indicators to Ethiopia

Competitiveness can be applied to predict the economic sustainability of tourism in destinations which has been measured in terms of leakages and linkage related to employment and income generation opportunities to the destinations. This article examines destination competitiveness of Ethiopia based on the analyses of administrative records, academic journals, face-to-face discussion with the key industry players and email communication. The main objective of this study is to assess sustainability of economic benefits of tourism for Ethiopia by applying destination competitiveness indicators. The result shows that potential destination competitiveness is significant for the growth of tourism and its economy especially to employment and income generation in Ethiopia. As the competitiveness of Ethiopia is being improved, it will result in the increase of tourist arrivals that will sustain economic benefits of tourism

A framework for habitat monitoring and climate change modelling: construction and validation of the Environmental Stratification of Estonia

Environmental stratifications provide the framework for efficient surveillance and monitoring of biodiversity and ecological resources, as well as modelling exercises. An obstacle for agricultural landscape monitoring in Estonia has been the lack of a framework for the objective selection of monitoring sites. This paper describes the construction and testing of the Environmental Stratification of Estonia (ESE). Principal components analysis was used to select the variables that capture the most amount of variation. Seven climate variables and topography were selected and subsequently subjected to the ISODATA clustering routine in order to produce relatively homogeneous environmental strata. The ESE contains eight strata, which have been described in terms of soil, land cover and climatic parameters. In order to assess the reliability of the stratification procedure for the selection of monitoring sites, the ESE was compared with the previous map of Landscape Regions of Estonia and correlated with five environmental data sets. All correlations were significant. The stratification has therefore already been used to extend the current series of samples in agricultural landscapes into a more statistically robust series of monitoring sites. The potential for applying climate change scenarios to assess the shifts in the strata and associated ecological impacts is also examined.</p

Betriebliche Bewirtschaftungsindikatoren für Biodiversität im Ökologischen Landbau und in extensiven Anbausystemen in Europa

Farming practices are the key to maintaining and restoring farmland biodiversity. Selected farm management indicators, regarded as scientifically sound, practicable and attractive to stakeholders, were tested against species indicators in various farm types in 12 case studies across Europe. A set of eight farm management indicators is recommended, reflecting the pressure on biodiversity by farm management via energy and nutrient input, mechanical operations, pesticide use and livestock

The Earth Observation Data for Habitat Monitoring (EODHaM) system

To support decisions relating to the use and conservation of protected areas and surrounds, the EU-funded BIOdiversity multi-SOurce monitoring System: from Space TO Species (BIO_SOS) project has developed the Earth Observation Data for HAbitat Monitoring (EODHaM) system for consistent mapping and monitoring of biodiversity. The EODHaM approach has adopted the Food and Agriculture Organization Land Cover Classification System (LCCS) taxonomy and translates mapped classes to General Habitat Categories (GHCs) from which Annex I habitats (EU Habitats Directive) can be defined. The EODHaM system uses a combination of pixel and object-based procedures. The 1st and 2nd stages use earth observation (EO) data alone with expert knowledge to generate classes according to the LCCS taxonomy (Levels 1 to 3 and beyond). The 3rd stage translates the final LCCS classes into GHCs from which Annex I habitat type maps are derived. An additional module quantifies changes in the LCCS classes and their components, indices derived from earth observation, object sizes and dimensions and the translated habitat maps (i.e., GHCs or Annex I). Examples are provided of the application of EODHaM system elements to protected sites and their surrounds in Italy, Wales (UK), the Netherlands, Greece, Portugal and India

The Network of Knowledge approach: improving the science and society dialogue on biodiversity and ecosystem services in Europe

The absence of a good interface between scientific and other knowledge holders and decision-makers in the area of biodiversity and ecosystem services has been recognised for a long time. Despite recent advancements, e.g. with the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), challenges remain, particularly concerning the timely provision of consolidated views from different knowledge domains. To address this challenge, a strong and flexible networking approach is needed across knowledge domains and institutions. Here, we report on a broad consultation process across Europe to develop a Network of Knowledge on biodiversity and ecosystem services (NoK), an approach aiming at (1) organising institutions and knowledge holders in an adaptable and responsive framework and (2) informing decision-makers with timely and accurate biodiversity knowledge. The consultation provided a critical analysis of the needs that should be addressed by a NoK and how it could complement existing European initiatives and institutions at the interface between policy and science. Among other functions, the NoK provides consolidated scientific views on contested topics, identification of research gaps to support relevant policies, and horizon scanning activities to anticipate emerging issues. The NoK includes a capacity building component on interfacing activities and contains mechanisms to ensure its credibility, relevance and legitimacy. Such a network would need to ensure credibility, relevance and legitimacy of its work by maximizing transparency and flexibility of processes, quality of outputs, the link to data and knowledge provision, the motivation of experts for getting involved and sound communication and capacity building

Indikatoren zur Erfassung genetischer Vielfalt in biologischen und nicht-biologischen Landwirtschaftssystemen

Genetic variability is the fundament of life. Large genetic variability within species is the basis for adaptation to changing environmental conditions. Farmers and breeders have developed a multitude of crop cultivars and animal breeds to stabilize and increase quality and productivity. This study evaluated genetic diversity within different organic and non-organic farming systems using crop-cultivar and livestock-breed information as simple indicators. Data was collected using on-farm surveys in 15 case study regions in Europe and beyond. Selected indicators revealed strong differences of cultivar diversity between different countries and farming systems across Europe. No or only small differences were detectable between organic and non-organic farming systems. Landraces, as on-farm genetic resources, were under-represented in European case study regions

BIOBIO – Indikatoren für Biodiversität in ökologischen und ex-tensiven Anbausystemen

Organic and low-input farming systems provide habitats for wildlife on farmland. The EU FP7 project BIOBIO has identified a core set of 23 indicators relating to the diversity of habitats, of species, of crops and of livestock. Management indicators capturing the pressure on biodiversity are also proposed. The indicators were identified in an iterative process between scientists and stake-holders to make sure that they are not only scientifically sound but also practicable and attractive. They were tested in 12 case study regions on four major farm types. Allocating 0.25 % of the CAP budget to a farm scale biodiversity monitoring would allow to measure and analyse the indicators on 50,000 farms across Europe

Indicateurs de biodiversité dans les exploitations agricoles biologiques et conventionnelles des Vallées et Coteaux de Gascogne, cas d’étude français du projet européen BIOBIO

Dans le cadre du projet européen BIOBIO, nous avons comparé entre pays les richesses en habitats et richesses spécifiques cumulées de quatre groupes taxonomiques (plantes, abeilles sauvages, araignées, vers de terre), de 169 exploitations biologiques ou conventionnelles appartenant à 10 pays. Pour le cas d’étude français, Vallées et Coteaux de Gascogne, les corrélations entre indicateurs directs (richesses spécifiques des taxons et habitats) et indirects (pratiques agricoles) de biodiversité, relevés dans 8 exploitations conventionnelles et 8 biologiques, ont été recherchées. Les résultats montrent que le nombre d’habitats cultivés et surtout semi-naturels par exploitation est le principal facteur déterminant le niveau de biodiversité à cette échelle, pour le cas d’étude français comme pour les autres cas d’étude. Ce facteur explique en partie le plus haut niveau de biodiversité observé pour le cas d’étude français. Néanmoins, les pratiques, spécifiques ou non des modes de production biologique et conventionnelle, gouvernent généralement les paramètres de biodiversité à l’échelle de l’habitat. In fine, le projet propose la méthode BIOBIO de suivi de la biodiversité dans les exploitations agricoles
