Climate Warming Effects on the Olea Europaea–Bactrocera Oleae System in Mediterranean Islands: Sardinia as an Example

Global Change Biology, April 2009, 15:2874–2884

Luigi Ponti , Q. Antonio Cossu, and Andrew Paul Gutierrez

“Global warming will affect all species but in largely unknown ways, with certain regions such as the Mediterranean Basin and its major islands including Sardinia being particularly vulnerable to desertification. Olive (Olea europaea) is of eco-social importance in the Mediterranean where it was domesticated. This drought-resistant crop and its major pest, the olive fly (Bactrocera oleae), have tight biological links that make them a suitable model system for climate change studies in the Mediterranean. Here a physiologically based weather-driven demographic model of olive and olive fly is used to analyze in detail this plant–pest system in Sardinia under observed weather (10 years of daily data from 48 locations), three climate warming scenarios (increases of 1, 2 and 3 °C in average daily temperature), and a 105-year climate model scenario for the Alghero location (e.g. 1951–2055). GRASS GIS is used to map model predictions of olive bloom dates and yield, total season-long olive fly pupae, and percent fruit attacked by the fly. Island wide simulation data are summarized using multivariate regression. Model calibration with field bloom date data were performed to increase simulation accuracy of olive flowering predictions under climate change. As climate warms, the range of olive is predicted to expand to higher altitudes and consolidate elsewhere, especially in coastal areas. The range of olive fly will extend into previously unfavorable cold areas, but will contract in warm inland lowlands where temperatures approach its upper thermal limits. Consequently, many areas of current high risk are predicted to have decreased risk of fly damage with climate warming. Simulation using a 105-year climate model scenario for Alghero, Sardinia predicts changes in the olive–olive fly system expected to occur if climate continued to warm at the low rate observed during in the past half century.”

Workshop on Workflows for Earth Observation Systems, University of Nottingham, on 21-22 June 2010

“International initiatives such as the Global Earth Observation System of Systems (GEOSS) and the Global Monitoring for Environment and Security (GMES) are making significant progress towards providing resources for the access, discovery, processing and publishing of earth observation data. It is necessary for organisations to develop capabilities within their workflows for applying earth observation data from satellite-based, airborne and in situ sensors.

“A workflow can be defined as a collection of tasks, carried out by software systems, humans, or a combination of both, and organized to accomplish some business process.[]. Within Earth Observation Systems and Geographic Information Systems (GIS), workflows are enacted through the orchestration or chaining of services.”

“This workshop will bring together researchers from various projects to exchange knowledge on strategies for earth observation workflows and to identify areas for future collaboration and development. The workshop will be hosted by the Open Source GIS UK conference, to be held at the University of Nottingham on 21st-22nd June 2010. Visit the website here.”

Environmental Modeling: Using Space Syntax in Spatial Cognition Research

Workshop & Tutorial at Spatial Cognition 2010
15 August 2010, Mt. Hood, Oregon

“Spatial cognition researchers have exacting methods for studying how people navigate, learn, and remember buildings, cities, and other large environments. Architects and planners have similarly careful computational methods for modeling the physical form of these environments. With this combination tutorial and workshop, we hope to further the pairing of behavioral methods and environmental models in spatial cognition research. The morning tutorial session will include a hands-on lesson in using environmental modeling techniques known as space syntax. No prior experience is necessary for the tutorial.

“For the afternoon workshop session, researchers and practitioners are invited to submit papers (short or long format) and posters (with an abstract) for presentation. Those who wish to attend without presenting are invited to submit a position paper. Topics to be considered include:

  • Using environmental models (axial maps, segment maps, isovists, visibility graph analysis, agents, etc.) to address theoretical questions concerning spatial knowledge, spatial learning, locomotion, wayfinding, and other topics in spatial cognition.
  • Methodological issues of pairing environmental models and behavioral research methods.
  • Constructing environmental models that capture psychologically relevant features.
  • Relating environmental properties, such as visibility, accessibility, and intelligibility, to cognitive processes and behavior.”

Friday, February 26, 2010, 4:00 p.m. to -5:30 p.m.

Location: University of Redlands, Gregory 161

“3D visualizations and other analysis tools assist local and regional planners in conveying ideas to the public to better inform citizens during the decision making phase of the local planning process.  A variety of tools and services have come about in the last few years that have greatly changed the process, from a monetary and process standpoint, to be one that is much more accessible in every way.

“The Metropolitan Area Planning Council is the planning agency for the 100 cities and towns surrounding Boston, and uses GIS to assist municipalities with zoning reform, site visualization, and community participation in the planning process.  This presentation will cover three projects undertaken by the agency from a GIS perspective.  The projects include a site visualization for Weymouth Landing, MA, a build-out analysis done for Malden, MA, and a 3d model of Boston’s Chinatown created for use in a planning video game for use at a planning meeting.”

United Nations University and ESRI to Collaborate on GIS Research and Training

GIS Technology Expanded to All 15 UNU Campuses

ESRI and United Nations University (UNU) recently approved a memorandum of understanding (MOU) at the university’s headquarters in Tokyo, Japan. They will collaborate on research, create Centers of Excellence, promote the exchange of graduate students, and provide geographic information system (GIS) training opportunities within and by UNU.

“This agreement will promote enhanced spatial information use in UNU’s research and education initiatives,” said UNU rector and under-secretary-general of the United Nations professor Konrad Osterwalder. “It will also support the increased presence of young researchers at UNU campuses and complement existing and planned research and education programs.”

Adds Michael Gould, ESRI director of education solutions, “The MOU will help connect promising graduate students to real-world problems, such as climate change, water resource management, food security, natural hazards, and sustainable development, and critical issues being researched at UNU institutes using GIS. ESRI is pleased to be able to support their efforts.”

UNU has used ArcGIS software since 2006. Projects include the Wildlife Enforcement Monitoring System, which documents and analyzes transboundary wildlife trade for monitoring purposes and compliance with the Convention on International Trade in Endangered Species of Wild Fauna and Flora. The university has also used GIS to assess flood risk and analyze climate and land-use change impacts on water resources in the Asia Pacific region.

A Predictive GIS Model for Potential Mapping of Copper, Lead, and Zinc in Langping Area, China

Geo-Spatial Information Science, Volume 12, Number 4 / December, 2009

Tarik. B. Benomar, Guangdao Hu, and Fuling Bian

“Mineral resource potential mapping is a complex analytical process, which requires the consideration and the integration of a number of spatial evidences like geological, geomorphological, and wall rock alteration. The aim of this paper is to establish mineral exploration model for copper, lead, and zinc in Lanping basin area using the capability of analytical tools of Geographic Information System (GIS) and remote sensing data to generate maps showing favorable mineralized area. The geo-exploration dataset used for the research includes copper, lead, and zinc deposits, geological maps, topographic maps, structural maps, and ETM+ imagery. Geological features indicative of potential copper, lead, and zinc were extracted from the datasets input in the predictive model. The method of weights of evidence modeling is a probability-based technique for generating mineral potential maps using the spatial distribution of indicative features with respect to the known mineral occurrences. The method of weights of evidence probabilistic modeling provides a quantitative method for delineating areas with potential of copper, lead, and zinc mineral deposits in the Lanping Basin area. weights (W+, W−) and contrast (C=(W+)-(W−)) calculations guide the data-driven modeling. The four most important spatial features for exploration guide for copper, lead, and zinc mineralization hosted in the Lanping Basin area are alteration zones, faults, host rocks, and lineaments. The host rocks and deep faults have the strongest spatial association with the known copper, lead, and zinc deposits. The hydrothermal alteration zones have the moderate spatial association with the copper, lead, and zinc deposits. The predicted high-favorability zones do not show the strong affinity with lineaments. The distribution of 22 (copper, lead, and zinc) occurrences in the Lanping Basin was examined in terms of spatial association with various geological phenomena. The analysis of these relationships using GIS and weights of evidence modeling has predicted areas of high and moderate mineral potential, where a little or no mining activities exist.”

MosquitoMap and the Mal-area Calculator: New Web Tools to Relate Mosquito Species Distribution with Vector Borne Disease

International Journal of Health Geographics 2010, 9:11

Desmond Foley, Richard Wilkerson, Ian Birney, Stanley Harrison, Jamie Christensen, and Leopoldo Rueda

“Mosquitoes are important vectors of diseases but, in spite of various mosquito faunistic surveys globally, there is a need for a spatial online database of mosquito collection data and distribution summaries. Such a resource could provide entomologists with the results of previous mosquito surveys, and vector disease control workers, preventative medicine practitioners, and health planners with information relating mosquito distribution to vector-borne disease risk.

“Results: A web application called MosquitoMap was constructed comprising mosquito collection point data stored in an ArcGIS 9.3 Server / SQL geodatabase that includes administrative area and vector species x country lookup tables. In addition to the layer containing mosquito collection points, other map layers were made available including environmental, and vector and pathogen/disease distribution layers. An application within MosquitoMap called the Mal-area calculator (MAC) was constructed to quantify the area of overlap, for any area of interest, of vector, human, and disease distribution models. Data standards for mosquito records were developed for MosquitoMap.

“Conclusion: MosquitoMap is a public domain web resource that maps and compares georeferenced mosquito collection points to other spatial information, in a geographical information system setting. The MAC quantifies the Mal-area, i.e. the area where it is theoretically possible for vector-borne disease transmission to occur, thus providing a useful decision tool where other disease information is limited. The Mal-area approach emphasizes the independent but cumulative contribution to disease risk of the vector species predicted present. MosquitoMap adds value to, and makes accessible, the results of past collecting efforts, as well as providing a template for other arthropod spatial databases.”
