To help overcome these problems, a global disaster emergency and relief agency should be established. As a move to this end, the UN can establish a global disaster emergency center in charge of policy and coordination among world members to alleviate the threats of major natural disasters.

Another option is that the world's current disaster relief resources be merged to realize information sharing among all countries so that the negative effects of any natural disasters can be reduced to a minimum.

The establishment of a global disaster surveillance and warning system is the key to improving the capability of individual nations in disaster prevention and risk control. Compared with developing countries, the developed countries enjoy more mature and advanced management expertise in this regard.

The establishment of such a global surveillance and warning system would help realize the sharing of resources and information worldwide and boost the disaster warning capability of developing nations.

For example, the responsibilities of countries, regions and international organizations should be explicitly defined in case of natural disasters so as to improve the efficiency of disaster mitigation efforts.

A joint relief mechanism should also be set up under the framework of the UN, and all member states should sign an accord that will bind them to offer specific assistance in the event of a natural disaster. International emergency drills should also be regularly organized to improve the disaster-relief capabilities of individual nations and international organizations.

Education on disaster prevention and relief should also be popularized among high-risk countries and regions to improve local people's awareness of what to do in the event of a natural disaster.

An international relief foundation should also be established to ease the world's current funding shortage. Currently, international funds for such purposes mainly depend on government and non-government donations on a voluntary basis, which often means limited funds that fail to meet the demands of worldwide relief work.

In view of this, a long-term and effective funding mechanism, such as the establishment of a global natural disaster insurance system, is desperately needed to resolve the funding shortage in global relief work.
