These technical briefs focus on low cost approaches to accessing clean water and sanitation. This is vital to health and well being and low costs are particularly important to poorer communities in the developing world.
Technical briefs are documents produced by Practical Action which are freely available to people in the developing world. They provide detailed technical information on a variety of subjects ranging from how to make jams and pickles to how to build a flood-proof house or an aerial ropeway.
As excellent secondary sources of information students can use technical briefs for research and to analyse and evaluate raw data. They are therefore excellent support materials for the new science national curriculum.
