Developing Countries face an array of traditional and modern lakes water quality problems ranging from faecal contamination to toxic chemicals. Moreover, they do so in an economic environment that is severely restricted, an institutional environment which is often poorly structured, and for which the modern scientific knowledge base is frequently poorly understood and applied. Agencies in many developing countries recognize this as major impediment to sustainable development, especially as water quality has become one of the leading economic issues for the purposes of development and investment. Generally water quality programmes tend to suffer from traditional approaches, both of methodology and legal/administrative. The Consequence is that many programmes on lakes water quality are grossly inefficient; produce often unreliable data and which are not generally useful for making management or investment decisions, and face decreasing economic and political support. Programme modernization is essential to achieve the twin goals of greater efficiency and greater relevance in meeting data needs for contemporary lakes water quality management purposes. Modernization reduces costs, may reduce the amount of equipment and infrastructure required, and more closely matches the abilities of developing countries where, for example, knowledge of advanced environmental chemistry may be limited but where knowledge of biological systems is strong.
