Pentingnya Analisis Lingkungan

Environment: A complex system with physical, biological, geological, ecological, and geopolitical aspects. (space, rocks, plants, buildings, laws)

Requires multidisciplinary research: chemistry, biology, physics, meteorology-climate, economics, ethics, law, Time, etc.

Environmental crisis: Population, environmental hazards, resource limitations and contaminations, environment ownership (both space and time)

Who really owns the earth???

ENVIRONMENTAL

Copy from George Stephenson MS, CPG in Environmetal Geology

KONSEP DASAR

• Five fundamental concepts Population growth – very critical – not

enough space and resources Sustainability – Don’t use it all up!!!

Systems and change – Work with the natural systems – not against them!

Hazardous Earth processes – inevitable

Scientific knowledge and values –observe and interpret - both impartially and correctly. In other words – the Scientific Method

HUMAN POPULATION GROWTH

• Population “time bomb”: Exponential growth

• Earth’s carrying capacity (how many can it hold without causing negative impacts) is limited: The more resources used, the more waste generated, the more land space needed

• Exponential growth Growth rate (G): measured as a percentage Doubling time (D): D = 70/G Currently 50 years - do the math!! Yikes! We now

have about 7 billion, in 50 years, 11 - 14 billion, in 100 years – 22-28 billion, 150 years 44-56 billion!

#1 Environmental problem (good test question)

SUSTAINABILITY

Sustainability – living so that our offspring will have equal access to our planet’s resources! The Earth will live on regardless, the main concern is the quality of the Human Environment (while we and ours are here on the Earth!!)

• An evolving concept – produce but conserve• Expectation and reality, be reasonable • Long-term implications, think it out carefully• Requiring careful resources allocation, development of

new technology and substitutions for resource use, recycling, reduction of products and waste, reusing – or designing reusable products!

Measuring sustainability – scientifically and ethically

• Use and consumption of resources• Replenishment and renewable rates• Development and improvement of human

environment vs. viable environment

• Essentially Responsible Development

Simple concept of sustainability, cut all the trees down, then you have no trees. Question, do we need trees – answer YES. Solution, cut and use only the amount of

trees that will be replaced by re-growth within the same time of resource usage!!

Hazardous Earth processes and risk statistics for the past two decades

• Annual loss of life: About 150,000• Financial loss: > $20 billion• More life loss from a major natural disaster in a

developing country (2003 Iran quake, ~300,000 people) (2004 Earthquake/Tsunami ~ 270,000)

• More property damage occurs in a more developed country (New Orleans)

Hazardous Earth Processes

Several Million people have died in the past 25 years alone!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

• Hazard identification

• Risk assessment (types, probability, and consequences of impact) Critical facility mapping and analysis Economic impact analysis Societal impact analysis Total environmental impact analysis

Risk AssessmentRisk management and mitigation

Why? Because when you have more people, it is likely that more of them live on harms way!!!!!

• Public attitude toward risks NIMBY (Not In My BackYard)

• Public acceptance for risks Threshold for living with dangers Planning decisions, e.g., floodplain

development, waste disposal site selection, using the scientific process

• Public awareness and collective actions Anticipatory measures Mitigation planning

Risk Perception- Education – Knowledge - Attitude

• Earth: A dynamic system of interdependence

• Four interconnected subsystems: Lithosphere (land and rock), atmosphere (air) hydrosphere (water), and biosphere (life )

• Earth systems science – study it all – and see how each relies on the other

• Four subsystems mutually adjust when one changes

• So – before you pollute the air, think what it might do to the land, water, or life!! ie. If you drive, you pollute rivers, therefore you kill fish!!

Earth’s Systems and Changes

• Goal is to Prolong Earth’s sustainable healthy life Environment monitoring Environment problems—mapping and

analysis Environment problem prevention and

protection – using a “systems” approach

• Science: is Accumulated knowledge

• Knowledge: is the Basis for decision making

• Scientific methods: a method to Formulate possible solutions to environmental problems

• Scientific design: Structures more suitable for certain environmental settings to achieve Sustainability

• Scientific Information: Public awareness and environmental regulations

Science and Solutions

• Methods to solve environmental problems have to be decided on by people, it is dependent on their (your) priorities.

• What are their priorities? What are yours?

• NOW - the ME attitude -- or

• Future - the care for your offspring attitude

Kesimpulan :Analisis Lingkungan berfungsi untuk mengukur sejauhmana kondisi lingkungan dengan adanya masalah populasi manusia dan bagaimana upaya mengelola lingkungan untuk dapat mendukung perikehidupan manusia (sustainability) pada generasi mendatang
