Processing Conservation Indicators With Open Source Tools: Lessons Learned From The Digital Observatory For Protected Areas, Lucy Bastin, Andrea Mandrici, Luca Battistella, Grégoire Dubois

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

The European Commission has a commitment to open data and the support of open source software and standards. We present lessons learnt while populating and supporting the web and map services that underly the Joint Research Centre's Digital Observatory for Protected Areas. Challenges include: large datasets with highly complex geometries; topological inconsistencies, compounded by reprojection for equal-area calculations; multiple different representations of the same geographical entities, for example coastlines; licensing requirement to continuously update indicators to respond to monthly changes in the authoritative data. In order to compute and publish an array of indicators, we used a range of open …

Assessing Mammal And Bird Biodiversity And Habitat Occupancy Of Tiger Prey In The Hukaung Valley Of Northern Myanmar, Hla Naing

Masters Theses

I used results from camera traps set for tigers (Panthera tigris) during 2001-2011 in the Hukaung Valley Wildlife Sanctuary of northern Myanmar to assess overall biodiversity of large mammal and bird species, and to identify differences in photo rates inside and outside of the most protected core area of the Sanctuary. A total of 403 camera stations were deployed during October-July in the dry seasons of 2001-2011, 260 inside the Core area and 143 Outside. From 10,750 trap-nights I obtained 2,077 independent photos of wildlife species and 699 of domestic animals and humans, including 35 species of wild …

Climate Change: Helping Nature Survive The Human Response, Will R. Turner, Bethany A. Bradley, Lyndon D. Estes, David G. Hole, Michael Oppenheimer, David S. Wilcove

Environmental Conservation Faculty Publication Series

Climate change poses profound, direct, and well-documented threats to biodiversity. A significant fraction of Earth’s species is at risk of extinction due to changing precipitation and temperature regimes, rising and acidifying oceans, and other factors. There is also growing awareness of the diversity and magnitude of responses, both proactive and reactive, that people will undertake as lives and livelihoods are affected by climate change. Yet to date few studies have examined the relationship between these two powerful forces. The natural systems upon which people depend, already under direct assault from climate change, are further threatened by how we respond to …

Greenways As Vehicles For Social Expression, Center For Economic Development

Center for Economic Development Technical Reports

Traditionally, the recognized functions of greenways include water resource protection and pollution abatement, riparian habitat enhancement and biodiversity, flood hazard reduction, recreation, environmental education, noise attenuation, microclimate enhancement (cooling and pollution abatement), and the reduction of bank erosion and downstream sedimentation (Platt, 1992). Phil Lewis simply prefers to think of greenways as environmental corridors, which he dubs "E-ways," for the four main purposes of environment, ecology, education, and exercise (1990). In this paper a fifth "e" purpose of expression will be suggested.

As a beginning four different ways of promoting expression will be illustrated with examples. These means will include …
