Criteria D assessment
Scientists are researching the best methods to reduce water scarcity and improve living conditions of people lacking sufficient water supply.
Your task is to research 2 methods to ensure a sustainable and sufficient water supply for a community of 100 people living on an island in the tropics.
The island has a warm climate with a short rainy season and a long dry season.
All food is grown on the island, only materials can be imported from the mainland.
Electricity is made using renewable energy resources.
The biggest problem the community is facing is the upcoming shortage of clean drinking water.
For this assessment you need to:
Explain how two methods can be used to solve the problem of providing drinking water on your island (one from each column of the table below).
Compare the two methods and decide on which you think is the best method. You need to explain why it is the best method too.
You need to evaluate the implications (positives and negatives) of your two methods in solving the problem. When doing this you should refer to at least one of the following factors: social, economic, political, environmental, cultural and ethical.
Present your work using a range of clearly described scientific terms and ideas.
Present information in a clear and logical way. Include pictures/graphics/diagrams to enhance your work.

Explanation:
Virtually every industry in the world anticipates sweeping systemic transformation over the next decade in their strategic planning, production practices, and business models, according to the Sustainability Survey Poll on Water. The global opinion poll, which released a survey of more than 1,200 sustainability experts in March, concludes that water shortages will shift public perception of the value of water, prompting governments and companies to view clean water not as a commodity to exploit but as a precious resource.
Conducted by GlobeScan, an international public and stakeholder opinion research firm, and SustainAbility, a think tank and business strategy consultancy, the poll asked, “What are the technologies or changes in behavior which show the most promise for addressing water shortages over the next 10 years?” The experts’ responses generated 19 consensus solutions.
Jeff Erikson, senior vice president at SustainAbility, told Circle of Blue that the decisions executives make to respond to freshwater scarcity will penetrate almost every aspect of their business operations. The varied solutions revealed the complexity of coping with water scarcity. Population growth, urban development, farm production and climate change are increasing competition for fresh water and producing shortages.
