Air is the colourless, odourless, tasteless gaseous mixture that surrounds the Earth. It is composed of nitrogen (78%) and oxygen (21%) and a mixture of other gases. Air and water are both necessary for life on Earth. Pollution of air by other gases or from dispersion of solid particles can occur as a result of human activity such as urbanisation and industrialisation.

Land is that part of the Earth’s surface that is not covered with water. To manage land sustainably means to manage it without damaging ecological processes or reducing biological diversity in terms of the variety of species, populations, habitats and ecosystems. It also means maintaining stores of natural capital such as fresh water and clean air.

Like air, water is essential to life on earth. Although much of the earth’s surface is covered with water, very little of it is suitable for human consumption and more than 10% of the world’s population do not have access to clean water. Water is also necessary for industry and agriculture so water allocation planning is necessary for the management of our water resources.

Waste refers to material which is no longer of use to its generator and is not being safely recycled. Waste does not exist in nature and occurs solely through human activity. It has social, environmental and economic costs.

Resources on Global Water Challenges and Related Business Risks

The UN Global Compact's CEO Water Mandate

Water poses one of the greatest sustainability challenges of the 21st Century. Water scarcity and pollution, among many other issues, threaten our ability to grow strong and stable economies, meet basic human needs, and protect healthy ecosystems (and the services they provide), while also posing severe human health problems.

Business organizations are greatly affected by – and also often contribute to – these important issues. Because of this, they are increasingly seeking more information and trying to understand how to address these challenges.

Launched in July 2007 by the UN Secretary-General, the CEO Water Mandate is a unique public-private initiative designed to assist companies in the development, implementation, and disclosure of water sustainability policies and practices.

The web site provides easy access to CEO Water Mandate governance documents, Mandate research and guidance materials, as well as resources developed by other organizations, initiatives, and businesses that are relevant to corporate water stewardship and the Mandate’s work.

 

Global Change Institute (UQ) - Healthy Oceans

Our oceans and coasts are changing at a rate unprecedented in human history. Ocean warming, acidification, rising sea levels, unsustainable fishing, pollution and coastal development are threatening the future of our marine environments, and the services they have provided to us in the past.

The University of Queensland's Global Change Institute features the following projects and resources focussing on " healthy ocean" issues -
