Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba
Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba
International Journal of Speleology
Endemic and rare species as bioindicators of habitat vulnerability were used to develop protection and management plans for biotope prioritization (mainly islands habitats, lava tubes or groundwaters). Due to their narrow distribution, the endemic species (species confined to a restricted geographic area) are more susceptible to ecological disequilibrium and habitat loss than the widespread ones. Consequently, endemics become endangered in the context of ecological disturbance caused by anthropogenic pressure, making them suitable candidates to assess environmental preservation needs. Taking into consideration that most of the stygobitic and troglobitic species are endemic and confined to specific karst areas, based on their …

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
This study aims to examine the relationship between temperature and precipitation as climatic factors and the vegetation characteristics in Forêt Classée de la Mondah (Gabon). A pixel based spatial analysis procedure with QGIS was used to extract vegetation characteristics from MODIS on Terra, NDVI band, data from February 2000 to December 2015, while temperature and precipitation were monitored from January 1980 to December 2015 to highlight climate fluctuations in the study area. Two regression analyses were conducted : one between temperature and NDVI and the other one between precipitation and NDVI. Results showed that temperature and precipitation did not vary …
Towards Food Service Sustainability In Suburban Environments By Optimally Locating Shared Anaerobic Digester Units, Rebecca Loraamm, Joni Downs, Robert Alonso Bair, Daniel Yeh
Towards Food Service Sustainability In Suburban Environments By Optimally Locating Shared Anaerobic Digester Units, Rebecca Loraamm, Joni Downs, Robert Alonso Bair, Daniel Yeh
Suburban Sustainability
Anaerobic digestion is an effective method for reducing food waste at the consumer level. Drawbacks associated with this strategy include high construction costs for multiple digester units and limited public awareness of the method’s commercial potential. Given the large scale problem of food waste, an approach establishing community partnerships between local businesses and primary schools is offered to combat the problem of food waste. Optimizing the placement of shared digester units enabling utilization by multiple stakeholders is the suggested mitigation method. This research explores application of the p-median problem to determine the set of optimal sites for shared anaerobic digester …
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
DePaul Discoveries
While we have a comprehensive understanding of air pollutants, and their spatiotemporal characteristics across global, and even regional, scales, we are quite limited in our capacity to monitor neighborhood-scale emissions. The mobile monitoring of air pollution is a growing field, prospectively filling in these gaps while personalizing air quality-based tools and risk assessment. In the present study, we developed wearable sensors for particulate matter (PM); and through a citizen science approach, students of partnering Chicago schools monitored PM concentrations throughout their commutes over a five-day period. While their recorded findings would be used to explore the relationship between PM concentrations …
Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets
Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets
Journal of Ocean and Coastal Economics
Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …
The Market Transfer Effect In The Hawaiian Longline Fishery: Why Correlation Does Not Imply Causation, Jason D. Scorse, Shaun Richards, Philip King
The Market Transfer Effect In The Hawaiian Longline Fishery: Why Correlation Does Not Imply Causation, Jason D. Scorse, Shaun Richards, Philip King
Journal of Ocean and Coastal Economics
A lot of discussion and controversy has surrounded whether the “market transfer” effect in the Hawaii longline swordfish fishery occurred during the swordfish closure of 2001-2004, because of its potential impacts on sea turtle mortality. The primary academic work in support of the market transfer effect during the closure is a paper by Rausser et al. (2009): “Unintended Consequences: The Spillover Effects of Common Property Regulations.” In this paper, the authors claim to find evidence in support of the market transfer hypothesis.To our knowledge, no analysis has yet been undertaken to assess whether this analysis is sound, and yet it …
Considerations Of Socio-Economic Input, Related Challenges And Recommendations For Ecosystem-Based Maritime Spatial Planning: A Review, Mavra Stithou
Considerations Of Socio-Economic Input, Related Challenges And Recommendations For Ecosystem-Based Maritime Spatial Planning: A Review, Mavra Stithou
Journal of Ocean and Coastal Economics
Socio-economics in an ecosystem-based Marine Spatial Planning (MSP) process cover a wide range from specifying socio-economic objectives, respective indicators, organising stakeholder engagement, to data, methods and tools (e.g., environmental valuation and cost-benefit analysis) for example to identify issues, assess ecosystem services, provide an insight on human behaviour and compare alternative marine plans with potentially competing goals. In addition, social principles such as that of social equity have an important role to play in achieving sustainability in marine management. However, the use of socio-economics in making the ecosystem-based MSP framework operational, poses certain challenges to researchers, regulators and policy-makers. The purpose …

This paper introduces the updated US-ModSoilParms-TEMPLE, which covers the entire United States and is organized as a framework of 22 nested and hydrologically-ordered regional geographic databases with internal spatial segmentation drainage-defined at a conveniently manageable tile (Watershed Boundary Dataset’s, WBD, 8-digit Subbasin) level. Spatial features are stored in multiple formats (raster and vector) and resolutions (10-meter and 30-meter), while being in direct relationship with the table of attributes …
Development And Environmental Injustice In Malaysia: A Story Of Indigenous Resistance In Sarawak, May Tay '17
Development And Environmental Injustice In Malaysia: A Story Of Indigenous Resistance In Sarawak, May Tay '17
EnviroLab Asia
In 2008, the Federal Government of Malaysian announced an initiative to build 20,000 megawatts of mega dams along a 320km corridor in Sarawak. Named the Sarawak Corridor of Renewable Energy (SCORE), the scheme would create one of five regional development corridors throughout Malaysia, and was part of the government’s strategy to make the state of Sarawak ‘developed’ by 2020 through industrialization and renewable energy development (Recoda). Of the mega dams planned for construction by 2020, three have been completed, with construction for the others underway and the construction process frequently delayed by resistance from local indigenous communities. Indigenous tribe members …
Considerations Of Development In Malaysian Borneo, Zayn Kassam
Considerations Of Development In Malaysian Borneo, Zayn Kassam
EnviroLab Asia
Given Malaysia’s vast natural resources, the country has embarked on an ambitious set of development projects capitalizing on the opportunities afforded by extractive industrialization. Global and national demand for oil palm products, timber, and hydropower resources coupled with a governmental development agenda guided by neoliberal market principles has led to both economic growth and social and environmental injustice. This chapter argues for an alternative development model along the lines suggested by Escobar in addressing Malaysia’s path to development and fiscal well-being in a manner that safeguards its cultural and natural resources.

This reflection touches on the writer’s experiences during the EnviroLab Asia Clinic trip in early 2016 to Borneo, Malaysia and Singapore. The reflection involves two events: a visit to a blockade protesting the construction of a hydroelectric dam and a meeting with the sustainability department of Wilmar, one of the world’s leading palm oil producers. The first event comments on the tension between the need for renewable energy and the destruction of the natural environment and communities due to the particular energy generation technology chosen. This event highlighted the importance of understanding the societal constraints a technology is being installed …

Resisting Dams And Plantations: Indigenous Identity In Sarawak, Wan Ping Chua '17
Resisting Dams And Plantations: Indigenous Identity In Sarawak, Wan Ping Chua '17
EnviroLab Asia
The market and community are always intertwined, and sustained through economic power, social obligations and ideologies. In Sarawak, Malaysia, the expansion of land use for the development of cash crops and energy infrastructure has faced resistance from indigenous communities who depend upon land for subsistence lifestyles. In this encounter, values and cultures are reworked, and the ways in which the community and market rely upon each other in the community changes. The examination of the rice and wild foods sustenance lifestyle of the indigenous Kenyah in Sarawak, Malaysia, and resistance against land development projects, suggest that in the conflicts over …

What Does “Sustainable Development” Mean?, Grace Stewart '17
What Does “Sustainable Development” Mean?, Grace Stewart '17
EnviroLab Asia
A recurring theme throughout the EnviroLab Asia clinic trip to Singapore and Malaysian Borneo was the concept of "sustainable development." In this essay, I explore my own thoughts and concerns regarding this phrase, such as the tension that exists between "sustainability" (the maintenance of resources) and the conventional concept of "development" (which consumes resources and can often wreak environmental destruction). I reflect on this tension within the context of environmental issues faced by the Dayak people in Sarawak--the building of the Baram Dam, and the prevalence of oil palm plantations.

In this reflection, Johann shares how the people he met on the trip (faculty, student fellows, activists and the indigenous people we lived with) furnished him with a lot of knowledge about his home country and the surrounding region and in the process shattered some misconceptions. He also contemplates how the experience prompted him to reevaluate his role as a consumer, activist, and future educator.

As economies continue to expand in Southeast Asia, urban and rural landscapes are undergoing industrial-scale change at a staggering pace. A number of growing industries are responsible for these changes, from soil and biodiversity loss caused by palm-oil deforestation to rainforest flooded in the interest of “climate neutral” hydropower. To best understand the wide-reaching effects of these transformations, a radically interdisciplinary approach is needed to unravel the intersection between environmental degradation, economics and culture. Is the quest for biofuels and carbon-neutral energy to support burgeoning largely urban populations, sometimes in other nations, effectively shifting the environmental costs to rural communities? …

EnviroLab Asia
Prior to leaving for Claremont Colleges’ Envriolab Asia trip to Malaysia and Singapore, I was conflicted by the question: Do we have the moral authority to interfere with resource extraction and oil-palm development in SE Asia? At that time, the trip seemed imperialistic. Why should people from Malaysia, Indonesia or any developing SE Asia country listen to a group of liberal arts college faculty from a city where widespread habitat modifications have led to significant loss of native habitats, declines in biodiversity, and changes in how these ecosystems function? Many observations transformed my opinion and have inspired me to advocate …

Academic knowledge of some of the inequities and injustices embedded in economic development was given greater depth and significance after the EnviroLab Asia clinic trip to Southeast Asia; the same was true result occurred after the group’s meeting with Dyack activists.
Re-Envisioning Sustainable Oil-Palm In Se Asia, Wallace M. Meyer Iii
Re-Envisioning Sustainable Oil-Palm In Se Asia, Wallace M. Meyer Iii
EnviroLab Asia
In Southeast Asia, expansion of oil-palm agriculture, in combination with other industries (logging, fiber, and mega-dams), is transforming significant portions of the landscape threatening biodiversity, key ecosystem services, and human cultural diversity. While transformative answers to these multifaceted environmental issues seem daunting, the conservation biology literature provides a road map for effective techniques to mitigate environmental degradation while allowing for thoughtful, well-planned economic growth. I suggest that the lack of strict operational definitions and a holistic approach to sustainability are the two most critical factors hindering development of sustainable oil-palm agriculture. The task for environmental practitioners is to succinctly define …
The Impacts Of Logging And Palm Oil On Aquatic Ecosystems And Freshwater Sources In Southeast Asia, Isabelle Ng '17
The Impacts Of Logging And Palm Oil On Aquatic Ecosystems And Freshwater Sources In Southeast Asia, Isabelle Ng '17
EnviroLab Asia
The process of deforestation has large environmental implications on terrestrial as well as aquatic habitats. Palm oil plantations lead to sedimentation and agricultural runoff into streams and rivers. Such high nutrient inputs could lead to eutrophication, bioaccumulation, and toxic blooms, which could lead to changes in aquatic ecosystems as well as drinking water quality for surrounding communities. Pollutants from streams and rivers are furthermore, channeled down into estuarine and coastal marine ecosystems, thus negatively impacting those areas as well. One possible way to reduce the amount of runoff is by treating the waste produced by palm oil mills as well …

Narratives About Energy, Megaprojects, And The Ecology Of Tropical Rivers: The Baram River Dam Project, Marc Los Huertos
EnviroLab Asia
The conflict between development goals to build dams for hydroelectricity and indigenous peoples in Sarawak was set in motion in the 1970s. In spite of the potential ecological damage, hydroelectric development has been justified by developed and developing countries for decades. These impacts include changes in river geomorphology, water quality, and habitat value and access. Moreover, in the Bakun and Baram river watersheds, the Dayak people of Sarawak have poignantly demonstrated the socio-ecological disruption. For the time being, the construction of the Baram Dam has been halted.

As the two leading palm oil producing countries, Indonesia and Malaysia have come under external pressures to limit deforestation and greenhouse gas emissions related to land use conversion for oil palm cultivation. We examine various institutional frameworks that have emerged to mediate these pressures. These frameworks can be distinguished by their geographic scope—domestic, region, and global—as well as by the nature of control—private, non-profit, and governmental. The frameworks have taken the form of sustainability certification systems from non-profit organizations or governments, corporate sustainability policies, or the setting through global or bilateral negotiations of voluntary national targets for limiting deforestation or …
