Reference excerpt

The International Drinking Water Decade or International Decade of Water or International Drinking Water Supply and Sanitation Decade, now known as The First Water Decade was the ten-year period 1981 - 1990 designated by the United Nations to bring attention and support for clean water and sanitation worldwide.

History The 1977 United Nations 'Water Conference' at Mar del Plata set up an International Drinking Water Decade, 1981-1990. Its aim was to make access to clean drinking water available across the world. The decade focussed on safe water and sanitation for everybody by 1990. Among the obstacles were the following: whether developing countries will give water and sanitary disposal high enough priority to get results; if an effective organization can be created within countries to carry out a water and waste programme; how manpower training and financing can be accomplished; and whether or not appropriate technology will be used. This first water decade, brought water to over 1.2 billion people and sanitation to almost 770 million. However, growth and rapid urbanization, together with the low level of public awareness about health, has drastically reduced many countries' abilities to keep up with need; and today, there are still almost 1.1 billion people who have inadequate access to water and 2.4 billion without appropriate sanitation. Since the decade ended in 1990, hopes for improvement are centred on the World Water Assessment Programme, a joint effort of the UN system and its member states, which includes a biennial assessment of the state of global freshwater resources. The launch of the second International Water Decade during 2005-2015 will also provide much needed impetus for the assessment program.

Worked examples

Example 1 — a first encounter with International Drinking Water Decade, 1981–90

Start with the simplest possible case. Write down what International Drinking Water Decade, 1981–90 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to International Drinking Water Decade, 1981–90 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about International Drinking Water Decade, 1981–90 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of International Drinking Water Decade, 1981–90

In research: International Drinking Water Decade, 1981–90 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses International Drinking Water Decade, 1981–90 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: International Drinking Water Decade, 1981–90 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drinking water, United Nations observances, so understanding it makes those chapters shorter.
In everyday life: Look for International Drinking Water Decade, 1981–90 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
