Water quality and peri-urban irrigation: an assessment of surface water quality for irrigation and its implications for human health in the peri-urban zone of Kumasi, Ghana

This technical note presents the findings of a study into wastewater quality and its use for informal irrigation in Kumasi, Ghana. It forms part of a wider study into the productivity and hazards of peri-urban irrigation taking place in Kumasi and Nairobi, Kenya

Reducing landslide risk in communities: Evidence from the Eastern Caribbean

Landslide risk reduction measures have been undertaken in a number of vulnerable unplanned communities in the Eastern Caribbean. The communities are located on hillsides which are known to be susceptible to landslides. Physically-based modelling demonstrates that the construction of simple retaining walls, a common practice at the individual household level, is unlikely to be an effective method of landslide risk reduction. A more appropriate approach is shown to be the comprehensive management of all forms of surface water through the construction of a network of drains to capture surface runoff, household roof-water and grey water. With reference to three major rainfall events, evidence is given of landslide risk reduction having been achieved though the implementation of such hillslope drainage measures. This study provides important, rare evidence of the impact of an ‘on-the-ground’, community-based, approach to landslide risk reduction. From a policy point of view, it suggests that a community-based approach to landslide risk reduction may well be applicable to vulnerable communities in the developing world, and indicates how such an approach maybe initiate

Studies of intermediate vector boson production and decay in U(A)(1) at the CERN proton - anti-proton collider

An extensive study of production and decay properties of charged and neutral Intermediate Vector Bosons (IVB) at the CERN proton-antiproton collider is presented. Intermediate Vector Bosons were detected in the electron, muon, and tau decay modes at centre-of-mass energies of 0.546 and 0.630 TeV. This paper is a summary, based on all the available data from the UA1 experiment from the running periods 1982-1985. Results are presented and compared with expectations of the Standard Eletroweak Model and QCD-improved Drell-Yan annihilation processes. The general conclusion is that there is an excellent agreement between the predictions of the Standard Model and our measurements. © 1989 Springer-Verlag
