Professor Steven Belmain completed his BA at the University of Vermont in 1990 before joining the Peace Corps and living in Mali, where his scientific interests became irreversibly entwined with overseas development. He then obtained an MSc and PhD at Birkbeck College, University of London.
Since joining NRI in 1998, Professor Belmain has become one of the leading international scientists researching the ecology of rodents as pests in agriculture and as disease vectors, with research activities across Asia and Africa aimed at helping rural and urban communities to overcome their pest problems. His research has been crucial in understanding the transmission risks of zoonoses as well as understanding the fundamental drivers of rodent population outbreaks. Professor Belmain also carries out research on the chemical ecology and behaviour of insects, and optimising the indigenous use of pesticidal plants.
As a principal investigator, Professor Belmain has travelled extensively across the world working on collaborative projects with counterparts in China, Vietnam, Bangladesh, India, Ghana, Mali, Sierra Leone, Tanzania, Mozambique, South Africa, Zimbabwe, Zambia, Namibia, Swaziland, Madagascar, Malawi, Belgium, Denmark, Netherlands, France and Australia. Professor Belmain has led many large multi-national and multi-disciplinary research projects with funding won from a wide range of donors including the UK's Department for International Development, the European Commission RTD Framework and EuropeAid EDF programmes, UNDP, WHO, and the McKnight Foundation. Dr Belmain's collaborations across entomology, small mammal ecology, and eco-epidemiology of zoonoses have led to a number of scientific publications, with an overall H-index of 16 and i-10 index of 23 (http://scholar.google.co.uk/citations?user=oG0Mo78AAAAJ).

Professor Belmain has given more than 30 presentations at scientific conferences, including several invited plenary and keynote addresses, and has led the organisation of several international conferences and workshops such as the International Conference on Rodent Biology and Management, the African Small Mammal Symposium, the International Conference on Pesticidal Plants, Impacts of Rodent Outbreaks on Food Security in Asia, and Rats and Human Health in Africa. Of particular note was the invitation to give the 22nd Annual MacCarthy Lecture in Pest Management at the University of British Columbia, Vancouver, Canada, on 12 March 2012.
Professor Belmain's research has attracted much media interest including articles on BBC Earth News, BBC News Magazine, Science Magazine and many radio and TV interviews, e.g. the Canadian Broadcasting Cooperation Quirks and Quarks programme and the BBC World Service's Science in Action and In The Field series. His efforts to raise awareness about rodents with the wider public are most notable in a 45-minute nature documentary commissioned for the Discovery Channel, Swarmchasers: Rats! The programme was first broadcast in the USA on 13 January 2011 and subsequently translated into 25 languages for broadcast to over 50 countries across Europe, Asia and Africa. Most recently he has appeared on ITV's Tonight news programme, The Rise of the Super Rats (http://www.itv.com/news/topic/tonight)
Professor Belmain's entomology interests are mainly focused on the chemical ecology and behaviour of insects, such as host orientation behaviour and optimising the use of plants with insecticidal properties. See projects.nri.org/options and projects.nri.org/adappt for details about a project in Africa that aims to improve the way farmers use local plants for pest control.
The use of plants for medicines and pest management has a long tradition and can be a cheap way for farmers to improve their yields. However, the production of bioactive chemicals in plants varies with climate and location and some popular wild plants can suffer from over-collection. His research aims to increase knowledge on the best ways of using pesticidal plants in order to help African farmers whilst ensuring the supply of high quality natural products.
More recently Professor Belmain has been involved in research on pollination biology and in a project that aims to improve the pollination of cocoa flowers to improve yields. See www.cocoapop.eu for more details about this project based in Jamaica and Trinidad & Tobago. If the project is successful in improving pod set and quality through better pollination, farmer incomes can rise without the need to expand cocoa plantations into virgin forest.
With rodents transmitting more than 60 diseases to people and domestic animals, damaging food production systems and exacerbating sanitation problems, few would argue that society's rat problems have been solved. But overcoming the challenges posed by rodents to our livelihoods is possible. A new paradigm of research, ecologically-based rodent management, is gaining momentum. Improving rodent management in the developing world could be one of the most important interventions of the 21st century to reduce poverty and improve people's livelihoods across the Tropics. See projects.nri.org/stoprats, projects.nri.org/ecorat , projects.nri.org/bandicoot and www.nri.org/ratzooman for examples of research projects that he has led about the agricultural and disease problems rodents cause.
Optimisation of Pesticidal-plants: Technology Innovation, Outreach & Networks: OPTIONs.
This project is funded by the European Development Fund ACP S&T programme. This EU programme aims to improve the capacity of science, technology and innovation across the Africa, Caribbean and Pacific Region. The OPTIONs project is led by the Natural Resources Institute, with Dr Belmain as co-principal investigator, and involves partners from the UK, Kenya, Tanzania, Malawi and Zimbabwe, namely: the Royal Botanic Gardens Kew; the World Agroforestry Centre; the University of Zimbabwe; Mzuzu University; Sokoine University of Agriculture; Sustainable Global Gardens; and the National Museums of Kenya.
With a budget of EUR1,175,000 from 2013–16, this multidisciplinary team aims to promote and facilitate the uptake of innovative technologies for improved food security based on pesticidal plants that can be effectively deployed within the context of local needs and resources. The project directly follows on from another European-funded project, the African Dryland Alliance for Pesticidal Plant Technologies: ADAPPT. More about this project can found at projects.nri.org/adappt
Sustainable Technology to Overcome Pest Rodents in Africa Through Science: StopRats.
This project is funded by the European Development Fund ACP S&T programme. This EU programme aims to improve the capacity of science, technology and innovation across the Africa, Caribbean and Pacific Region. The StopRats project is led by the Natural Resources Institute, with Professor Belmain as principal investigator, and involves partners from the UK, Namibia, South Africa, Swaziland, Tanzania, Sierra Leone and Madagascar, namely the University of Namibia; the University of Swaziland; the University of Venda; Sokoine University of Agriculture; the Plant Protection Research Institute – Agricultural Research Council; Concern Worldwide; and the Association Vahatra.
With a budget of EUR1,168,000 from 2013–16, this multidisciplinary team aims to strengthen science, technology and innovation about rodent biology and management and contribute to African sustainable development by enabling institutions to address key indicators of poverty through the impacts of rodents on agricultural production systems and food security. This project expands upon previous European funding in the EcoRat project, more about this project can be found at projects.nri.org/ecorat
Safe and effective pesticidal plants for agro-ecological intensification of legumes
This project is funded by the McKnight Foundation, an independent private philanthropic charity established by the McKnight family in the United States to improve the quality of life for present and future generations. See: www.mcknight.org
The project involves partners at the Nelson Mandela African Institute of Science and Technology in Tanzania, the Lilongwe University of Agriculture and Natural Resources in Malawi, the Pyrethrum Growers Association of Kenya, McLaughlin Gormley King, a company in the USA, and the Royal Botanic Gardens, Kew, UK with Professor Belmain from the Natural Resources Institute acting as lead principal investigator. This four-year project (2013–17) builds on a previous four years of funding provided by McKnight, providing the continuity to address complex issues related to improving access to high quality ecosystem services for pest management in legume production.
Legumes (cowpea, beans, pigeon pea) are the most nutritionally important staple commodity in Africa because they are rich in protein and micronutrients such as iron and zinc, with many essential vitamins found in the leaves and fresh pods. Because animal sources of protein are relatively expensive, beans are especially important for poor households and have an important role in childhood nutrition and development, and household food security. The project ultimately aims to ensure safe pesticidal plant products that can help develop value chains for local pest management resources.
Cocoa Pollination for Optimised Production: CocoaPOP
This project is funded by the European Union's Caribbean and Pacific Research Programme for Sustainable Development (2012–15). Involving partners in Jamaica and Trinidad & Tobago, the project aims to investigate ways to improve the pollination of cocoa.
As global demand for chocolate increases, farmers try to meet this by expanding their cocoa plantations, often converting natural forest. Despite the commercial nature of cocoa production, very little is actually known about its pollination and the pollinating insects found in different regions. Unlike most crops, cocoa is not pollinated by bees, and instead relies on small flies, called midges.
Rodent outbreak management to improve livelihoods of African farmers
This project is funded by the Agricultural Technology Transfer programme, AgriTT, with funding from the UK Department for International Development. The project is led by Professor Belmain and involves partners at the Institute of Zoology, Chinese Academy of Sciences, China and the Pest Management Centre, Sokoine University of Agriculture, Tanzania. The main aim of the project is to evaluate the prospect of Chinese fertility control technology to control rodent populations using fertility control hormones within an African context. Population outbreaks occur both in China and Africa, but the rodent species are different as are the general ecological, social and economic conditions. Chinese researchers have shown their fertility control baits work against a number of species in Chinese grassland habitats prone to population outbreaks; hence, there is good reason to hypothesize that the main grassland savannah rodent species found in Africa should be similarly susceptible. However, susceptibilities vary and efficacy in an African context must be evaluated, not only to ensure it works, but that it is safe for the environment, cost-effective, socially accepted and able to improve livelihoods by preventing severe agricultural losses.
