Poverty, health and satellite-derived vegetation indices: their inter-spatial relationship in West Africa

International Health, Vol. 7, No. 2. (March 2015), pp. 99-106,


[Background] Previous analyses have shown the individual correlations between poverty, health and satellite-derived vegetation indices such as the normalized difference vegetation index (NDVI). However, generally these analyses did not explore the statistical interconnections between poverty, health outcomes and NDVI. [Methods] In this research aspatial methods (principal component analysis) and spatial models (variography, factorial kriging and cokriging) were applied to investigate the correlations and spatial relationships between intensity of poverty, health (expressed as child mortality and undernutrition), and NDVI for a large area of West ...


Climate twins - An attempt to quantify climatological similarities

IFIP Advances in Information and Communication Technology In Environmental Software Systems. Frameworks of eEnvironment, Vol. 359 (2011), pp. 428-436,


As climate change appears, strategies and actions will be necessary to cope with its effects on environment and society in the coming decades. Current climate conditions can be observed everywhere in the world but future climate conditions can only be estimated through climate simulations which produce huge amounts of quantitative data. This data leads to statements like “temperature increase is expected to exceed 2.6°C” or similar and remain fuzzy to non-experts in climate research. The Climate Twins application is designed to ...


Meteorological droughts in Europe: events and impacts - Past trends and future projections



[Excerpt: Executive Summary] Observational records from 1950 onwards and climate projections for the 21st century provide evidence that droughts are a recurrent climate feature in large parts of Europe, especially in the Mediterranean, but also in western, south-eastern and central Europe. Trends over the past 60 years show an increasing frequency, duration and intensity of droughts in these regions, while a negative trend has been observed in north-eastern Europe. With a changing climate, this tendency is likely to be reinforced during the 21st century, affecting a wide range of ...


Strengthening protected areas for biodiversity and ecosystem services in China

Proceedings of the National Academy of Sciences, Vol. 114, No. 7. (14 February 2017), pp. 1601-1606,


[Significance] Following severe environmental degradation from rapid economic development, China is now advancing policies to secure biodiversity and ecosystem services. We report the first nationwide assessment, showing that protected areas (PAs) are not well delineated to protect either biodiversity or key ecosystem services. This serious deficiency exists in many countries. We propose creating a national park system in China to help guide development along a path of green growth, improving the well-being of both people and nature. This involves establishing new, strictly ...


Terrestrial ecosystems, soil and forests

In Climate change, impacts and vulnerability in Europe 2016 - An indicator-based report, Vol. 1/2017 (January 2017), pp. 153-182,


[Excerpt: Key messages] [::] Observed climate change has had many impacts on terrestrial ecosystems, such as changes in soil conditions, advances in phenological stages, altitudinal and latitudinal migration of plant and animal species (generally northwards and upwards), and changes in species interactions and species composition in communities, including local extinctions. [::] The relative importance of climate change as a major driver of biodiversity and ecosystem change is projected to increase further in the future. In addition to climate change, human efforts to mitigate and adapt to ...

Meteorological aspects of forest fire danger rating

Journal of the South African Forestry Association, Vol. 29, No. 1. (1 January 1957), pp. 31-38,


The effect of past weather conditions on inflammability and the influence of weather on fire behaviour are discussed. Using a method of deriving inflammability from rainfall, temperature and humidity data the frequency of days of high inflammability in January, February and March in the Cape over eight years is derived and shows a maximum in mid-February. With the use of a burning index meter daily values of fire danger rating at the Cape for the same months in 1953–1955 are derived. ...

Travel time to major cities: a global map of accessibility



[Excerpt: Background] The world is shrinking. Cheap flights, large scale commercial shipping and expanding road networks all mean that we are better connected to everywhere else than ever before. But global travel and international trade and just two of the forces that have reshaped our world. A new map of Travel Time to Major Cities - developed by the European Commission and the World Bank - captures this connectivity and the concentration of economic activity and also highlights that there is little ...


Mapping and assessing the condition of Europe's ecosystems: progress and challenges - EEA contribution to the implementation of the EU Biodiversity Strategy to 2020

No. 3/2016. (2016),


[Excerpt: Executive summary] We depend on healthy and resilient ecosystems to continue to deliver a range of essential services, such as food, water, clean air and recreation, into the future. However, our natural capital is being lost to or degraded by pressures such as pollution, climate change, overexploitation and urban development. The EU Biodiversity Strategy to 2020 therefore sets a target to maintain and enhance ecosystems and their services by establishing green infrastructures and restoring at least 15 % of degraded ecosystems by 2020. Mapping ecosystems and their condition is essential for measuring ...

We use the directed networks between articles of 24 Wikipedia language editions for producing the Wikipedia Ranking of World Universities (WRWU) using PageRank, 2DRank and CheiRank algorithms. This approach allows to incorporate various cultural views on world universities using the mathematical statistical analysis independent of cultural preferences. The Wikipedia ranking of top 100 universities provides about 60 percent overlap with the Shanghai university ranking demonstrating the reliable features of this approach. At the same time WRWU incorporates all knowledge accumulated at 24 Wikipedia editions giving stronger highlights for historically ...


Multispecies indicators 2015

In Pan-European Common Bird Monitoring Scheme (PECBMS) (2015), 592


Supranational species indices are combined in multispecies indicators. These are produced for groups of species according to their main habitat types. To produce precise indicators with small standard errors, it is important to include as many bird species as possible. The rationale behind the construction of composite indicators is that each species is seen as a replicate that may respond in the same way to environmental drivers as the other species and repeats the same signal. [\n] After the supranational species indices ...


Wild bird indicators: using composite population trends of birds as measures of environmental health

Ornithological Science, Vol. 9, No. 1. (1 June 2010), pp. 3-22,


World leaders have set global and regional targets to reduce the rate of biodiversity loss by 2010, and their relative success, or failure, in meeting these aims will be measured against a set of indicators. For such indicators to be effective, they need to meet a range of practical and scientific criteria. Their development is often driven pragmatically by the information available, One such biodiversity indicator that has proven highly effective and influential in Europe is the wild bird indicator. This ...


Towards more predictable and consistent landscape metrics across spatial scales

Ecological Indicators, Vol. 57 (October 2015), pp. 11-21,


[Highlights] [::] Landscape metrics are used to quantify landscape composition and configuration. [::] These metrics are sensitive to spatial pattern and the scale of the spatial data. [::] Metrics that are less sensitive to scale and are less correlated are highlighted. [::] Complex interactions between scale and the spatial pattern of the landscape were found. [::]Investigation of these interactions is needed to accurately quantify spatial patterns. [Abstract] Habitat change and fragmentation are considered key drivers of environmental change and biodiversity loss. To understand and mitigate the effects of ...


Landscape fragmentation assessment using a single measure

Wildlife Society Bulletin, Vol. 28, No. 4. (2000), pp. 875-881


Measurement of fragmentation is crucial for determining its consequences and to develop policy for nature conservation. We propose a fragmentation measure |Φ| which combines, using a multidimensional Euclidean distance, 4 main characteristics of frag-mented landscapes: total habitat area, total habitat perimeter, number of patches, and patch isolation. Its properties can be summarized as: 1) |Φ| reflects the overall fragmen-tation status; 2) every component of |Φ| is accepted as a measure of fragmentation; 3) every component of |Φ| is a normalized variable; ...

Fractal dimension of a transportation network and its relationship with urban growth: a study of the Dallas - Fort Worth area

Environment and Planning B: Planning and Design, Vol. 31, No. 6. (2004), pp. 895-911,


A city and its transportation network are both complicated systems. Fractal geometry provides an effective way to describe the complex property of geographical features. This paper uses a modified box-counting method to describe the fractal property of urban transportation networks. Assuming that human settlements of different sizes are all operated by the same growth procedure, this paper investigates the relationship between the mass size of cities and the complexity of their road systems. The results confirm that, as cities grow from ...


Landscape indices as measures of the effects of fragmentation: can pattern reflect process?

Vol. 98 (2003)


This review examines landscape indices and their usefulness in reflecting the effects of ecosystem fragmentation. Rapid fragmentation of natural ecosystems by anthropogenic activity spurred the development of landscape indices, which occurred in three phases. In proliferation, indices were introduced to quantify aspects of fragmentation, including composition, shape, and configuration. In re-evaluation, several studies demonstrated that landscape indices vary with varying landscape attributes, correlate highly with one another, and relate differently to different processes. Finally, in re-direction, efforts shifted towards developing new or modified indices motivated by ecological theory or incorporating ...


A national assessment of green infrastructure and change for the conterminous United States using morphological image processing

Landscape and Urban Planning, Vol. 94, No. 3-4. (15 March 2010), pp. 186-195,


Green infrastructure is a popular framework for conservation planning. The main elements of green infrastructure are hubs and links. Hubs tend to be large areas of ‘natural’ vegetation and links tend to be linear features (e.g., streams) that connect hubs. Within the United States, green infrastructure projects can be characterized as: (1) reliant on classical geographic information system (GIS) techniques (e.g., overlay, buffering) for mapping; (2), mainly implemented by states and local jurisdictions; and (3) static assessments that do not routinely ...


Mapping and analyzing landscape patterns

Landscape Ecology In Landscape Ecology, Vol. 9, No. 1. (1 March 1994), pp. 7-23,


Landscapes were mapped as clusters of 2 or 3 land cover types, based on their pattern within the clusters and tendency for a single type to dominate. These landscapes, called Landscape Pattern Types (LPTs), were combined with other earth surface feature data in a Geographic Information System (GIS) to test their utility as analysis units. Road segment density increased significantly as residential and urbanized land cover components increased from absent, to present as patch, to present as matrix (i.e., the dominant ...


mfSBA: Multifractal analysis of spatial patterns in ecological communities

F1000Research, Vol. 3 (7 April 2014), 14,


Multifractals have been applied to characterize complex communities in a spatial context. They were developed for nonlinear systems and are particularly suited to capture multiplicative processes observed in ecological systems. Multifractals characterize variability in a scale-independent way within an experimental range. I have developed an open-source software package to estimate multifractals using a box-counting algorithm (available from and permanently available at The software is specially designed for two dimensional (2D) images such as the ones obtained from remote ...


A new habitat availability index to integrate connectivity in landscape conservation planning: Comparison with existing indices and application to a case study

Landscape and Urban Planning, Vol. 83, No. 2-3. (19 November 2007), pp. 91-103,


Connectivity is a major concern for the maintenance of wildlife populations, ecological flows, and many other landscape functions. For these reasons many different connectivity indices have been used or proposed for landscape conservation planning; however, their properties and behaviour have not been sufficiently examined and may provide misleading or undesired results for these purposes. We here present a new index (probability of connectivity, PC) that is based on the habitat availability concept, dispersal probabilities between habitat patches and graph structures. We ...

Sensitivity of Landscape Pattern Metrics to Map Spatial Extent

Photogrammetric Engineering & Remote Sensing, Vol. 2001 (2001), pp. 1027-1036


Computation of landscape pattern metrics from spectrally classified digital images is becoming increasingly common, because the characterization of landscape spatial structure provides valuable information for many applications. However, the spatial extent (window size) from which pattern metrics are estimated has been shown to influence and produce biases in the results of these spatial analyses. In this study, the sensitivity of eight commonly used landscape configuration metrics to changes in map spatial extent is analyzed using simulated thematic landscape patterns generated by the modified random clusters method. This approach makes it possible to ...


Effects of remote sensor spatial resolution and data aggregation on selected fragmentation indices

Landscape Ecology In Landscape Ecology, Vol. 19, No. 2. (2004), pp. 197-209,


Analyzing the effect of scale on landscape pattern indices has been a key research topic in landscape ecology. The lack of comparability of fragmentation indices across spatial resolutions seriously limits their usefulness while multi-scale remotely sensed data are becoming increasingly available. In this paper, we examine the effect of spatial resolution on six common fragmentation indices that are being used within the Third Spanish National Forest Inventory. We analyse categorical data derived from simultaneously gathered Landsat-TM and IRS-WiFS satellite images, as ...


Mapping ecosystem service supply, demand and budgets

Ecological Indicators, Vol. 21 (October 2012), pp. 17-29,


[Abstract] Among the main effects of human activities on the environment are land use and resulting land cover changes. Such changes impact the capacity of ecosystems to provide goods and services to the human society. This supply of multiple goods and services by nature should match the demands of the society, if self-sustaining human–environmental systems and a sustainable utilization of natural capital are to be achieved. To describe respective states and dynamics, appropriate indicators and data for their quantification, including quantitative ...


Development of a composite index of urban compactness for land use modelling applications

Landscape and Urban Planning, Vol. 103, No. 3-4. (December 2011), pp. 303-317,


This paper introduces a composite index to characterise urban expansion patterns based on four associated indices that describe the degree of compactness of urban land: nuclearity, ribbon development, leapfrogging and branching processes. Subsequently, principal component and cluster analysis are applied to build the composite index. Two baseline scenarios and three hypothetical policy alternatives, run from 2000 to 2030 using the pan-European EU-ClueScanner 1 km resolution land use model are then used to test the sensitivity and robustness of the composite index ...


Effects of different matrix representations and connectivity measures on habitat network assessments

Landscape Ecology (2014), pp. 1-20,


Assessing landscape connectivity is important to understand the ecology of landscapes and to evaluate alternative conservation strategies. The question is though, how to quantify connectivity appropriately, especially when the information available about the suitability of the matrix surrounding habitat is limited. Our goal here was to investigate the effects of matrix representation on assessments of the connectivity among habitat patches and of the relative importance of individual patches for the connectivity within a habitat network. We evaluated a set of 50 × 50 km2 ...


Supplementary materials for: a proposal for an integrated modelling framework to characterise habitat pattern



In Estreguil et al. (Environ Modell Softw 52, 176-191, 2014), an integrated modelling framework is proposed to characterise habitat pattern. The modelling approach is there exemplified by deriving a set of twelve indices aggregated into four categories: general landscape composition, habitat morphology, edge interface and connectivity. The easy and reproducible computability is ensured with the integrated use of publicly available software (GUIDOS free-download software, Conefor free software) and of newly programmed tools. A statistical analysis is then conducted using classical linear ...


Climate change, connectivity and conservation decision making: back to basics

Journal of Applied Ecology, Vol. 46, No. 5. (October 2009), pp. 964-969,


The challenge of climate change forces us to re-examine the assumptions underlying conservation planning. [\n] Increasing ‘connectivity’ has emerged as the most favoured option for conservation in the face of climate change. [\n] We argue that the importance of connectivity is being overemphasized: quantifying the benefits of connectivity per se is plagued with uncertainty, and connectivity can be co-incidentally improved by targeting more concrete metrics: habitat area and habitat quality. [::Synthesis and applications] Before investing in connectivity projects, conservation practitioners should ...


Profiling core-periphery network structure by random walkers

Scientific Reports, Vol. 3 (19 March 2013),


Disclosing the main features of the structure of a network is crucial to understand a number of static and dynamic properties, such as robustness to failures, spreading dynamics, or collective behaviours. Among the possible characterizations, the core-periphery paradigm models the network as the union of a dense core with a sparsely connected periphery, highlighting the role of each node on the basis of its topological position. Here we show that the core-periphery structure can effectively be profiled by elaborating the behaviour ...

A Preliminary Assessment of Montréal Process Indicators of Forest Fragmentation for the United States

Environmental Monitoring and Assessment In Environmental Monitoring and Assessment, Vol. 91, No. 1-3. (2004), pp. 257-276,


As part of the U.S. 2003 National Report on Sustainable Forests, four metrics of forest fragmentation – patch size, edge amount, inter-patch distance, and patch contrast – were measured within 137 744 non-overlapping 5625 ha analysis units on land-cover maps derived from satellite imagery for the 48 conterminous States. The perimeter of a typical forest patch is about 100 m from the perimeter of its nearest neighbor, except when there is not much forest, in which case that distance is 200 ...

Vegetation diversity and vertical structure as indicators of forest disturbance

Forest Ecology and Management, Vol. 195, No. 3. (July 2004), pp. 341-354,


Plant species composition and vertical structure of oak-mixed Atlantic woodlands differing on disturbance regime were studied in the Basque Country, northern Spain. Four different disturbance groups were considered depending on the time since last thinning and the presence/absence of grazers. Plant species cover varied among disturbance groups for 17 out of the total 47 species present in the study area. In general, disturbance by clear-cutting favoured the cover of Betula alba, Castanea sativa and Quercus robur. The shrub species most affected ...

Use and misuse of landscape indices

Landscape Ecology, Vol. 19, No. 4. (1 May 2004), pp. 389-399,


Landscape ecology has generated much excitement in the past two decades. One reason was that it brought spatial analysis and modeling to the forefront of ecological research. However, high expectations for landscape analysis to improve our understanding and prediction of ecological processes have largely been unfulfilled. We identified three kinds of critical issues: conceptual flaws in landscape pattern analysis, inherent limitations of landscape indices, and improper use of pattern indices. For example, many landscape analyses treat quantitative description of spatial pattern ...


An a posteriori measure of network modularity



Measuring modularity is important to understand the structure of networks, and has an important number of real-world implications. However, several measures exists to assess the modularity, and give both different modularity values and different modules composition. In this article, I propose an a posteriori measure of modularity, which represents the ratio of interactions between members of the same modules vs. members of different modules. I apply this measure to a large dataset of 290 ecological networks, to show that it gives ...


Description of the indices implemented in EUDIC software for the European meteorological forest fire risk mapping

(May 2000)


EUDIC is a software developed in the frame of a collaboration between the Department AGROSELVITER of the University of Turin and the Space Application Institute of the Joint Research Centre. The software is aimed to compute daily a number of meteorological fire danger indices in Europe, using as input either measured meteorological data from the MARS database or forecasted weather data from MeteoFrance. The output are raster maps of the European Mediterranean basin or other portions of the European territory, ...


Ranking European regions as providers of structural riparian corridors for conservation and management purposes

International Journal of Applied Earth Observation and Geoinformation, Vol. 21 (April 2013), pp. 477-483,


Riparian zones are of utmost importance in providing a wide range of ecological and societal services. Among these, their role in maintaining landscape connectivity through ecological corridors for animals and plants is of major interest from a conservation and management perspective. This paper describes a methodology to identify European regions as providers of structural riparian corridors, and to rank them with reference to conservation priority. Physical riparian connectors among core habitat patches are identified through a recent segmentation technique, the Morphological ...


Global biodiversity: indicators of recent declines

Science, Vol. 328, No. 5982. (28 May 2010), pp. 1164-1168,


In 2002, world leaders committed, through the Convention on Biological Diversity, to achieve a significant reduction in the rate of biodiversity loss by 2010. We compiled 31 indicators to report on progress toward this target. Most indicators of the state of biodiversity (covering species’ population trends, extinction risk, habitat extent and condition, and community composition) showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity (including resource consumption, invasive alien species, nitrogen pollution, overexploitation, and climate ...


Domains of scale in forest-landscape metrics: Implications for species-habitat modeling

Acta Oecologica, Vol. 36, No. 2. (18 March 2010), pp. 259-267,


Observational scale defines the field-of-view used to quantify any set of data, and thus has profound implications on the development and interpretation of species-habitat models. However, most multi-scale studies choose observational scales using criteria unrelated to how metrics quantify along the scale continuum; scale choice is either arbitrary or via orders of resource selection irrespective of potential among-scale differences in mean or variation. Here, I use GIS to examine these issues for 9 forest-landscape metrics across 15 observational extents (while holding ...


Network analysis to assess landscape connectivity trends: application to European forests (1990–2000)

Ecological Indicators, Vol. 11, No. 2. (19 March 2011), pp. 407-416,


Landscape networks and ecosystems worldwide are undergoing changes that may impact in different ways relevant ecological processes such as gene flow, pollination, or wildlife dispersal. A myriad of indices have been developed to characterize landscape patterns, but not all of them are equally suited to evaluate temporal changes in landscape connectivity as is increasingly needed for biodiversity monitoring and operational indicator delivery. Relevant advancements in this direction have been recently proposed based on graph theoretical methods to analyze landscape network connectivity ...


Reporting on European forest fragmentation: standardized indices and web map services

IEEE Earthzine, Vol. 5, No. 2. (2012), 384031


This paper responds to the need for improved reporting and methodology reproducibility on forest fragmentation as underlined in the biodiversity policy context. The fragmentation of a focal ecosystem is conceptualized from a landscape pattern characterization based on three publicly available landscape models (Morphological Spatial Pattern application of the GUIDOS free download software, Landscape Mosaic Pattern, Conefor Sensinode free open source software) that were partly combined. A set of indices were derived and organized into five main families: two indices on general landscape ...
