This booklet synthesizes findings from analysis of agricultural policy and performance in three African countries: Cameroon, Ghana and Mali. Case studies of each of these countries were undertaken as part of the Support for African Agriculture Project (SAAP), a project largely financed by the...

The purpose of this test is to measure the time course of biodegradation of a test substance at low concentration in aerobic natural water and to quantify the observations in the form of kinetic rate expressions. The test is performed in batch by “pelagic test” or “suspended sediment...

This Test Guideline describes two simulations tests used in the aerobic sewage treatment. Activated Sludge Units are designed to determine the elimination and the primary and/or ultimate biodegradation of water-soluble organic compounds by aerobic micro-organisms in a continuously operated test...
