cost-benefit analysis that refers to the value people get from a natural resource compared to not having it
TEV= UV (usevalue) + NUV (non-usevalue)
Use value
• value derived from the actual direct or indirect use of the resource or service
Option value - value that people place on having the option to enjoy something in the future, although they may not currently use it.
Non-use / Passive use values
Existence values - non-use value that people place on simply knowing that the resource exists, even if they will never see it or use it
Bequest value - value that people place on knowing that future generations will have the option to enjoy something.
Why would drivers of change impact biodiversity and ecosystem services?
Disruptions in living systems can impact the material world, while changes in the physical environment affect living organisms.
Humans rely on ecosystems for food, resources, and clean water, but their ability to manipulate the environment has caused significant disturbances, posing threats to both the biosphere & human survival
Aquaculture
habitat simplification and pollution, leading to deadzones in water bodies.
decline in marine biodiversity
caused by overfishing, global warming, etc
Syntheticinputs (fertilizers and antibiotics)
worsen issues of biodiversity loss and disruption of natural cycles since they cause imbalances in soil and water nutrient distribution
Philippines
considered as a biodiversityhotspot, with urgent conservation efforts needed in many areas
