India

2000-2002. Team leader for a collaborative project, with the Indian Grain Storage and Management Research Institute and a local NGO – Centre for Environmental Concerns. The project will test and validate approaches that link village-level institutional development to the choice and development of grain management systems appropriate to institutional needs. The target group consists of women’s groups formed from landless households. The main output of the project will be a set of policy guidelines on decentralised, community-based approaches to the provision of village-level food security.

Ghana, Zimbabwe and Tanzania

November 1999 – 2002. Team leader of a research project on IPM methods for Larger Grain Borer (Prostephanus truncatus), working with the Postharvest Management Division (Ghana), Plant Protection Research Institute (Zimbabwe) and Plant Protection Division (Tanzania). Risk assessment methods will be validated for LGB, a method of limiting the amount of pesticides that farmers need to apply on stored grain is being developed and extended and the potential for improving biological control of LGB using the predator Teretrius nigrescens is being examined.

Ghana

1996-1999. Team leader of a research project, with the Post Harvest Development Unit, to develop a risk assessment system for the Larger Grain Borer (Prostephanus truncatus). The project is funded as part of DFID’s Renewable Natural Resources Research Strategy (RNRRS). The objective of the project was to enable extension services to predict when and where LGB infestation is likely to be severe and hence target their resources rationally.

Ghana

1999 (1 week). Consultant on behalf of the Cocoa Association of London to audit the pest management activities of the Ghana Cocoa Board and to advise on best practice to reduce the need for fumigation in destination countries.

India

1999 (1 week). Project reviewer on behalf of the Australian Centre for International Agricultural Research for their project on ‘Phosphine Resistance in Insect pests of Stored Grain’.

India

1996-1997 (8 weeks). Technical advisor to a collaborative research project with ICRISAT and NARS to investigate the post-harvest constraints to sorghum in southern India. The project used a combination of participatory rural appraisal and technical sampling to investigate the socio-economic and technical constraints affecting sorghum storage and utilisation in selected areas of Maharashtra, Karnataka and Andra Pradesh. The project was supported by funding from DFID as part of its RNRRS.

Kenya

1994-1996 (2 months). Team leader of a research project, based at Nakuru, to investigate the use of carbon dioxide from local volcanic sources, to replace methyl bromide as a means of fumigating maize stocks held in concrete silos. The project was a joint collaboration between the Kenya Agricultural Research Institute, Carbacid CO₂ Ltd (a commercial producer of CO₂) and NRI, with funding from DFID bilateral funds for Kenya. The project resulted in a viable CO₂ fumigation technique with cost comparisons with other stock protection options.

Kenya

1995 (3 weeks). Technical director for a video production on ‘Good Practice for Phosphine Fumigation’. The video was made in collaboration with the National Cereals and Produce Board and the Kenya Agricultural Research Institute, with funding from DFID. The video has been distributed widely in developing countries and is available from NRI.

Indonesia

1994-1995 (4 months). Team leader of a multi-disciplinary project (involving bimetricians, computer programmers and storage technologists) to develop a computerised decision support system, based around an insect trapping methodology developed earlier, to optimise pest management in milled rice storage systems. The project was undertaken in collaboration with the National Logistics Agency (BULOG) and funded by DFID. The developed methodology has been selected by the Australian Centre for International Agricultural Research for incorporation into its larger expert system for the management of milled rice stores.

West Africa

1994 (6 weeks). Team leader of multidisciplinary survey (storage technologists/socio economists) to assess the threat of the Larger Grain Borer in West Africa and develop recommendations for a sub-regional project to limit the effects of this pest. Visits made to 11 countries over a period of six months. The final report detailed the situation in West Africa and indicated how an appropriate project could be implemented. The survey was undertaken on behalf of Directorate General VIII of the European Union.

Tanzania

1993 (3 weeks). Technical director for a video production on the Larger Grain Borer. The video was designed to create awareness among the extensions services and plant protection agencies through out East Africa of the threat posed by this pest and the action that could be taken against it. Funding was from the FAO/EU Larger Grain Borer Phytosanitary project. The video was prepared in three languages and is widely available throughout Africa. Copies can be obtained from NRI.

Eritrea

1993 (10 days). Technical consultant to establish whether a consignment of food aid wheat was fit for human consumption. Arbitration was required between the recipients (the Ethiopian Red Cross), the shippers, the World Food Programme and local EU representatives on appropriate disposal and to instruct on necessary phytosanitary measures. An agreement was reached that was acceptable to all parties. The consultancy was undertaken on behalf of the EU.

Mexico/Togo/Kenya

1991-1994. Manager of the Integrated Pest Management Initiative on the Larger Grain Borer. This project had three field bases and management responsibility was to co-ordinate the work programme between the bases, to assess and steer the on-going programme by regular visits to the bases and provide quality control for outputs. The project was funded by UK Regional Funds to Africa (DFID). The project outputs gave rise to improved understanding of the biology of the pest and resulted in the implementation of a biological control programme in East Africa.

Ghana

1991 (6 weeks). Team leader of a study with the Ghana Food Distribution Corporation to investigate the efficacy of insecticide sprays to limit insect pest populations in warehouses. Project funded by DFID. The final report was published as part of a broader paper on insecticide usage which clearly indicates that little is gained from many types of insecticide application and urges improvement in practice.

Indonesia

1987-1991. Pest and Quality Control Advisor on full-time appointment to the National Logistics Agency (BULOG), undertaking evaluations of stock preservation strategies, research into improved commodity management and the provision of training in post-harvest technology. Funded as part of the UK Technical Co-operation Programme (DFID). Besides technology transfer two important outcomes of the project were improved methodologies for sealed bag stack storage and a clear demonstration that routine insecticide application on bag stack surfaces is not a cost-effective means of pest management. The results form the basis to the latest recommendations on pest management in stores published by FAO.

Mali

1985-1987. Pest and Quality Control Advisor on full-time appointment to the Agricultural Marketing Board (OPAM) on stock protection and quality control for routine stocks and national food security reserves. Funded as part of the UK Technical Co-operation Programme (DFID). The project provided technical and managerial support to the Stock Protection Service and, by collaboration with the GTZ-funded National Food Security Service, maintained food security throughout Mali. Responsibility was also held for representing the UK on the Project for Restructuring the Cereal Market (PERM).

Indonesia

1983-1984 (4 months). Team leader of a collaborative study with the Indonesian National Logistics Agency (BULOG), to investigate a means of monitoring insect pest populations in milled rice stores. The project was funded by DFID and resulted in the identification of a means of making reasonably accurate estimates of insect population on which it would be possible to base pest control decisions.

Brazil

1982 (6 weeks). Team leader for a research project with the cocoa research centre (CEPLAC) to demonstrate how synthetic pheromones can be used to limit reproduction of moths in cocoa stores. This involved determining the minimum concentration of airborne pheromone and maximum moth population densities for successful control by confusion. Follow-up studies to this have demonstrated how the pheromone should be dispensed for efficient pest management. Recently, Brazilian authorities have been working with the FDA (USA) to gain clearance for the use of this method in freight containers carrying cocoa to the USA. The work was funded by DFID.

Tanzania

1981-1983 (8 weeks). Technical advisor for DFID-funded survey and research work on the Larger Grain Borer (Prostephanus truncatus). This work was undertaken in collaboration with the Department of Plant Protection and provided the first account of this exotic pest in Africa and formed the basis to future projects to contain and control it.
