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 …

Indigenous People, Development And Environmental Justice: Narratives Of The Dayak People Of Sarawak, Malaysia, Elizabeth Weinlein '17
EnviroLab Asia
Focusing on the indigenous people of Sarawak, this article explores the authors learned biases as well as the dispelling of myths through hands on experiences in Malaysia. Over the period of a couple days, it becomes apparent that the indigenous people in Sarawak are not victims of systems of oppression, but survivors who continue to fight for their land rights and livelihoods.

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? …

Transformation, Wallace M. Meyer Iii
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.

Institutional Responses To Pressures For Sustainable Palm Oil, Stephen Marks, Justin Lauw '18, Shivang Mehta '19, Fernando Salud '17
EnviroLab Asia
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 …

A New Approximation Scheme For Monte Carlo Applications, Bo Jones
A New Approximation Scheme For Monte Carlo Applications, Bo Jones
CMC Senior Theses
Approximation algorithms employing Monte Carlo methods, across application domains, often require as a subroutine the estimation of the mean of a random variable with support on [0,1]. One wishes to estimate this mean to within a user-specified error, using as few samples from the simulated distribution as possible. In the case that the mean being estimated is small, one is then interested in controlling the relative error of the estimate. We introduce a new (epsilon, delta) relative error approximation scheme for [0,1] random variables and provide a comparison of this algorithm's performance to that of an existing approximation scheme, both …

First Passage Statistics For The Capture Of A Brownian Particle By A Structured Spherical Target With Multiple Surface Traps, Alan E. Lindsay, Andrew Bernoff, Michael J. Ward
All HMC Faculty Publications and Research
We study the first passage time problem for a diffusing molecule in an enclosed region to hit a small spherical target whose surface contains many small absorbing traps. This study is motivated by two examples of cellular transport. The first is the intracellular process through which proteins transit from the cytosol to the interior of the nucleus through nuclear pore complexes that are distributed on the nuclear surface. The second is the problem of chemoreception, in which cells sense their surroundings through diffusive contact with receptors distributed on the cell exterior. Using a matched asymptotic analysis in terms of small …

Quantifying Carbonyl Sulfide And Other Sulfur-Containing Compounds Over The Santa Barbara Channel, Julia Black
Scripps Senior Theses
Carbonyl sulfide (OCS) is emitted to the atmosphere through the outgassing of ocean surface waters. OCS is also the primary source of sulfur-containing compounds in the stratosphere and contributes to the formation of the stratospheric sulfate layer, an essential controller of the radiative balance of the atmosphere. During the 2016 Student Airborne Research Program (SARP), 15 whole air samples were collected on the NASA DC-8 aircraft over the Santa Barbara Channel. Five additional surface samples were taken at various locations along the Santa Barbara Channel. The samples were analyzed using gas chromatography in the Rowland-Blake lab at UC Irvine, and …

Paving The Randomized Gauss-Seidel, Wei Wu
Scripps Senior Theses
The Randomized Gauss-Seidel Method (RGS) is an iterative algorithm that solves overdetermined systems of linear equations Ax = b. This paper studies an update on the RGS method, the Randomized Block Gauss-Seidel Method. At each step, the algorithm greedily minimizes the objective function L(x) = kAx bk2 with respect to a subset of coordinates. This paper describes a Randomized Block Gauss-Seidel Method (RBGS) which uses a randomized control method to choose a subset at each step. This algorithm is the first block RGS method with an expected linear convergence rate which can be described by the properties of the matrix …

Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles
Pomona Senior Theses
Groundwater has been very important to the economic development of Southern California, and will continue to be a crucial resource in the 21st century. However, Climate Change threatens to disrupt many of the physical and economic processes that control the flow of water in and out of aquifers. One groundwater manager, the Six Basins Watermaster in eastern Los Angeles and western San Bernardino Counties, has developed a long-term planning document called the Strategic Plan that mostly fails to address the implications of Climate Change, especially for local water supplies. This thesis presents an in-depth analysis of the Six Basin Watermaster’s …
