As part of Water in the landscape, consider the advantages and disadvantages of water to a locality in a less economically developed country (LEDC), eg management of the Nile drainage basin; see www.globaleye.org.uk go to "Index" and "Water" (PoS 6c).
Malaria could be the focus for a case study to develop an understanding of development issues (PoS 6 i). Map its distribution and relate this to levels of economic development; see Global Atlas of Infectious Diseases http:globalatlas.who.int Not all LEDCs are as badly affected as others - why? How does malaria affect their economies? The incidence of malaria in the more developed world suggests a number of questions for enquiry: why is malaria still found in these countries? Where did it come from? How did it get there? What can be done about it?
Malaria offers the opportunity to pull together physical, human and environmental themes. Draw a flow diagram to show the knock-on effects of the disease: impact on family income, productivity, care for the land.
Investigate case studies of eradication projects - see www.who.inten Compare the advantages and disadvantages of the possible ways of controlling malaria, with particular reference to the effects of DDT.
