Answer. 1. Rio-Summit produced conventions dealing with climate change, biodiversity, forestry and recommended a list of development practices called Agenda 21.

  1. It gave the concept of sustainable development to be combined economic growth with ecological responsibility.
  2. Rio-Summit developed various contentious issues like Commons, Global Commons in global politics of environment.
  3. What is meant by Global Commons? How are they exploited and polluted?

 Answer. The areas or regions located outside the jurisdiction of any one state and region, common governance by international community are Global Commons i.e. Earth atmosphere, Antarctic Ocean floor and outer space. They are exploited and polluted due to

  1. Vague scientific evidences, their lack of consensus on common environmental issues.
  2. North-South inequalities and their exploitative activities and competition lack proper management area out space.
  3. Technological and Industrial development have also affected the earth's atmosphere and ocean floor.
  4. What is meant by 'Common but differentiated responsibilities'? How could we implement the idea?

Answer. Common but differentiated responsibili-ties mean that the state shall cooperate in the spirit of global partnership to conserve, protect and restore the health and integrity of the earth's ecosystem. As the states have common but differentiated responsibilities over various contributions of global environmental degradation. The developed countries acknowledge that the responsibility that they bear in the international pursuit of sustainable development in view of the pressures their societies place on the global environment and of the tech-nological and financial resources they command. We could implement the idea with the help of conventions and declarations:

  1. The Rio-Summit held in June 1992 produced conventions dealing with climate change, biodiversity, forestry and recommended a list of developed practices called Agenda 21.
  2. The 1992 United Nations Framework convention on climatic change (UNFCCC) also emphasised that the parties should act to protect the climate system on the basis of common but differentiated responsibilities;
  3. An international agreement known Kyoto Protocol set targets for industrialised countries to cut their greenhouse gas emissions which support for global warming .
  4. Why have issues related to global environmental protection become the priority concern of states since the 1990s?

 Answer. Issues related to global environmental protection became the priority concern of states since the 1990s because at global level, the environmental issues drew attentions of various states at the United Nations Conference on Environment and Development held in Rio-de-Janerio, Brazil in June 1992 through Agenda 21:

  1. Rio-Summit 1992 dealt with climatic change, bio-diversity and forestry.
  2. Agenda 21 combined economic growth with ecological responsibilities. 3. Kyoto Protocol set targets for greenhouse emissions. The above mentioned conferences and summits raised the environmental issues at the global level to take steps by various states to check environmental degradation in a co-operative manner.
  3. Compromise and accommodation are the two essential policies required by states to save Planet Earth. Substantiate the statement in the light of the ongoing negotiations between the North and South on environmental issues.

 Answer. Compromise and accommodation are the two essential policies to save Planet Earth by the states but the states from North and South have different notions towards environmental issues:

  1. The Northern States (Developed) are concerned with ozone depletion and global warming whereas southern states (Developing) want to address the relationship between economic development and environmental management.
  2. The developed countries of the North want to discuss the environmental issues which stand equally responsible for ecological conservation.
  3. The developing countries of the south feel that much of the ecological degradation in the world is create. by developed countries through their industrial projects.
  4. And if developed countries cause more environmental degradation they are supposed to take more responsibility onwards.
  5. The developing counties are under process of industrialization and they should be exempted from restrictions imposed on developed countries through various conventions like protocol etc.
  6. The special needs of developing countries must be taken into considerations in the process of development, application and interpretation of rules of International Environmental Law. All the above mentioned provisions were accepted in Earth Summit, 1992 while adopting common but differentiated responsibilities.
  7. The most serious challenge before the states is pursuing economic development without causing further damage to the global environment. How could we achieve this? Explain with a few examples.

Answer. The economic development can be achieved even without damaging global environment by following practices:

  1. In June 1992, Earth Summit provided some conservative measures for sustainable growth without damaging environment anymore.
  2. The Antarctic Treaty of 1959 covered Global Commons for mutual economic development.
  3. Kyoto protocol cut greenhouse emissions from industrialised countries to protect environment and to develop industries also.
  4. Resource Geopolitics allocates and ' distribute natural resources among the nation states of global arena for sustainable development of nations. Hence, the above mentioned practices protect the global environment and even though the states are developing we could achieve this challenge only if we follow the provisions and practices mentioned in all these conferences and summits.
