UK Manager of 4 year Migrant Pest Project for IRLCO-CSA that required continuous research inputs on control techniques (red locust, grasshopper, Quelea, armyworm) and financial management. Author of the winning NRI bid. Client: AfBD
Aquatic and terrestrial ecology (2w). Consultancy for the Gov.o Botswana on ecological methods for monitoring non-target populations of invertebrates and fish in the Okavango River and swamps in relation to the assessment of risks of pyrethroid use for tsetse control. Client: ODA
Ecotoxicology. (5m) Ecological impact of deltamethrin sprayed aerially for the control of tsetse fly on dynamics of lake plankton and riverine benthos in N E Zimbabwe.
Monitoring of aerosol spray drift on standing populations, activity and behaviour of aquatic and terrestrial invertebrates. Ecotoxicological studies on soil nitrification and N2-fixation activity of diazotrophes. Client: Wellcome Foundation
Ecotoxicology. (6m) Risk assessment of ground-sprayed DDT used to control tsetse in W Zimbabwe. Monitoring over three years the dissipation and degradation of DDT from vegetation and soils, and the effect of DDT and its metabolites on the breakdown and removal of leaf litter by surface fauna and soil micro- and macro-infauna. Training on pesticide application and safety. Client: ODA
Environmental monitoring (1m) of aquatic organisms and fish following aerial overspray of endosulfan (tsetse control) over small water bodies in Choma area. Invertebrate and fish monitoring to gauge standing crop and recovery following severe acute mortalities. Client: EC DGVIII
Environmental monitoring (1.5m) of key soil processes influencing soil fertility.
Impact of endosulfan used for tsetse control on soil nitrification and respiration in woodland soils. Portable monitoring technology developed and tested. Client: EC
Pesticide safety and ecotoxicology. (2m). Monitoring the safety of ground-spraying crews and the ecological impact of deltamethrin in rivers: spray drift of pyrethroid insecticides used to control tsetse fly in western Zimbabwe. Surface dwelling and benthic aquatic fauna were monitored (drift) or quantified (standing populaton) above and below source of contamination to establish the extent and degree of the impact. Research and training in operator safety from hydraulic pressure sprayers. Client: Veterinary Dept Zimbabwe & ODA
Ecological Impact Assessment (2m) Ecological impact of acridicides used for control of locust and grasshoppers. Pilot study to determine major effects of fenitrothion, chlorpyriphos and diflubenzuron on aquatic and terrestrial fauna and key soil microbial functions were compared. Client: ODA/FAO
Environmental monitoring (1m), to assess the impact of insecticide spraying (riverine tsetse control) on non-target invertebrates, fish and fishery of the Shabeelle River. Physico-chemical monitoring of water and analyses of endosulfan residues in water, sediments and animal tissues provided dispersion characteristics and toxicological data for ADIs. Client:ODA
