Biodiversity and nature management

Biodiversity and  nature management - variation is the planet's life insurance

Around 50% to 80% of the earth's species I’ve in tropical rainforests. Here the biological diversity is big. Biological diversity is a collective term for all of the variations in nature. The most important reasons why biodiversity is lost is the destruction of habitats, pollution, overexploitation, alien species and climate change. A biodiversity ensures access to different genes and works therefore as the planet's life insurance.

Nature management - how should we use nature?

Nature management is about making rules on how to use nature so that we get the most out of it. This could for example be the preservation of coral reefs and tropical forests. The decision of when we can hunt or not is also nature management.

Nature management in developing countries - several conflicts of interest

In many developing countries, the question regarding nature management can be a difficult question - especially between the goal of sustainable development and the wish of the locals. When the tropical forest in Brazil is cut down, it can be a question of living or not living for those people who need the fields for livestock or to make money by selling lumber. In this case, it is hard to choose sustainable development.

Sustainable fishery - quotas to take care of the stock

Today we have an effective way to fish. Without nature management regarding fishery, would the stock quickly become too big or too small. With knowledge about the ecology and population growth of fish, we can fish without ruining the stock. This makes sure we have a sustainable fishery.

Predators - when diversity costs

Norway has committed itself to securing the viable stock of wolves through an international agreement called the Bernkonvensjonen. The agreement is about taking care of biological diversity. We have for example committed to make the wolf can establish themselves in the country.
