Hazards
potential source of harm
potential threats to humans and their welfare (ex: infrastructures, food supplies, economy)
ex: typhoon, flood, earthquake
Risk
likelihood that harm from a specific hazard will occur
probability of occurring and severity of an adverse effect to health, property, or the environment
risk = hazard * exposure
Exposure
the people, property, systems, or other elements present in hazard zones that are thereby subject to potential losses
hazard + exposure = risk
Vulnerability
the inability to resist hazard or respond effectively when a disaster occurs
The Risk Triangle
D. Crichton, 1999
if any of these sides increases, then the amount of risk also increased
Disaster
levels of disruption and lose beyond a community’s ability to cope by themselves (without external assistance)
ex: 2013 Typhoon Yolanda (6,200 deaths)
#NonNaturalDisaster
a hazard can only become a disaster once it impacts on society or community that is not adequately protected and whose population is vulnerable as a result of poverty p, social exclusion, or social disadvantages
hazards may be natural, disasters are not
Increased Occurrence of Disasters
serious environmental degradation
lack of planning and foresight
lack of consciousness
Environmental Management
orchestration of human activities towards the common goal of balancing
environmental, social, and economic objectives
Nature of Environmental Problems
environmental problems are complex and long term
environment is a system
effective environmental management has to be integrative and holistic
when two species share an ecological niche (they require the same resources), one will outcompete the other, potentially leading to decline or extinction
Competitive Exclusion Theory
two species competing for the exact same resources cannot stably coexist
effective environmental management aims to manage ecosystems to prevent competitive exclusion
Ecology
a key element in integrated environmental management
there has to be a minimum degree of environmental literacy or basic understanding of ecology
there is a need to understand, respect, and work with the laws of nature to which all human activities are subjected
everything is connected to everything else
an environmental principle
organisms and ecosystems are all linked in complex webs of interaction
human activities have direct and indirect consequences
short-term and long-term effects on the local fish populations → local economy → regional economy
short-term: loss of habitat, disruption of food supply, water quality degradation
long-term: decline in fish population, loss of biodiversity, disrupted ecosystem balance, reduced fishery yields
everything goes somewhere
an environmental principle
“linear thinking”
unlimited source of raw materials, highly consumptive lifestyle, easy waste disposal, wastes will just disappear
but… nature’s processes are cyclical
nothing is free
every action in an ecosystem has a cost, often with trade-offs that impact other species or the environment as a whole
we may choose to ignore these costs but sooner or later we’ll have to pay for them
Economics
a key element in integrated environmental management
student of production, distribution, and consumption of goods and services
Law of Scarcity
under economics
resources are scarce and therefore there is a need to manage them
Full-cost Pricing
under economics
pricing strategy that incorporates all direct and indirect costs associated with the production, distribution, and environmental impact of a product or service
aims to reflect the true cost of a product
when water is abundant or free, people tend to waste it
price of safe and potable water should reflect the cost of maintaining watersheds and protecting water bodies
typical price of gasoline
extraction, refining, and distribution costs
costs related to GHG emissions, air pollution, or health effects
full-cost pricing and additional costs would be reflected to encourage a shift toward cleaner energy sources
Economic Incentives and Disincentives
under economics
examples:
a. a paper company that has imported a water recycling technology from Germany may be exempted from import tax
b. selected industries surrounding the Laguna Lake are required to pay a fee for draining their wastewater into the lake
c. the greater the volume and the more polluted the wastewater drained = the higher the fee
Law and Policy
a key element in integrated environmental management
deals with the protection, conservation and management of natural resources
while laws are important in environmental management, these are not sufficient to address environmental problems
Forestry Law of 1863
enacted by the Spanish Colonial Government
aims to manage and protect the Philippines’ forest resources, which were abundant but increasingly at risk due to exploitation
Philippine Environmental Policy (Presidential Decree 1151)
signed in 1977; first comprehensive environmental policy in the country landmark legislation that laid the foundation for environmental protection, management and enhancement in the Philippines
purpose: to protect and improve air quality in the country through comprehensive pollution control measures
key provisions: sets emission standards for motor vehicles and industries, promotes alternative fuels, and enforces air quality monitoring systems
Philippine Clean Water Act of 2004 (Republic Act No. 9275)
purpose: to protect the country's water bodies from pollution and to ensure sustainable management of water resources
key provisions: Regulates wastewater discharge, establishes water quality standards, and mandates the development of local water quality management areas
Ecological Solid Waste Management Act of 2000 (Republic Act No. 9003)
purpose: to provide a comprehensive and ecological waste management program
key provisions: promotes waste segregation at the source, mandates recycling and composting programs, and enforces penalties for improper waste disposal
Wildlife Resources Conservation and Protection Act (Republic Act No. 9147)
purpose: to conserve and protect wildlife species and their habitats
key provisions: regulates hunting, collection, and trade of wildlife; mandates the creation of wildlife sanctuaries; and imposes penalties for violations
Renewable Energy Act of 2008 (Republic Act No. 9513)
purpose: to promote the development and use of renewable energy sources in the country
key provisions: offers incentives for renewable energy projects, establishes Renewable Portfolio Standards, and promotes net metering for small power generators
Climate Change Act of 2009 (Republic Act No. 9729)
purpose: to address climate change through a framework for adaptation and mitigation
key provisions: establishes the Climate Change Commission, promotes local climate adaptation plans, and integrates climate change considerations into national and local development plans
Science and Technology
a key element in integrated environmental management
science: systematic study of the natural world
technology: application of scientific knowledge to create tools, systems, and solutions that solve problems or improve processes
in the past, environmental problems were looked upon as mostly technological problems
air pollution industrial emissions → scrubbers, filters vehicular emissions → catalytic converters technological solutions are not enough
many environmental problems we have today have been brought about by technologies that make production fast and efficient
high resource extraction, high waste accumulation
Renewable Energy Development
under science and technology
science: scientific foundation on renewable energy sources
technology: technological advancements in solar panels, wind turbines, and battery storage allow for more efficient and widespread use of renewable energy
Climate Change Mitigation and Adaptation
science: climate science informs us about the causes and effects of climate change and potential adaptation strategies
technology: carbon capture and storage, renewable energy solutions, resilient infrastructure development
Ethics
a key element in integrated environmental management
discipline dealing with moral duty and obligation
science of the ideal human character
most of the problems we have today can actually be linked to how we view the world and our ethics
we need an environmental ethic that has roots in:
traditional cultures
value the environment
prescribe practices meant to preserve harmony with the environment
social responsibility
dictate that all people have the right to benefit equitably from the environment
includes intergenerational equity
religion
respect the environment as the creation of a supreme being
