Oxford Long-Term Ecology Lab

Long-Term Ecology, Biodiversity Conservation, and Environmental Stewardship Technologies

Herizo completed his Forest Engineer degree in 2000 and his DEA (MSc) on ecology and development in 2009 both with distinction at the Department of Forestry University of Antananarivo Madagascar. He also completed with distinction his Postgraduate diploma in international wildlife conservation practice at the Wildlife Conservation Research Unit, Department of Zoology University of Oxford in 2009.

Herizo is a conservation practitioner with interests in ecological monitoring and GIS. He devotes most of his time to designing methods of participatory ecological monitoring and identifying the best ways to achieve conservation success in developing countries such as Madagascar. He has worked for Durrell Wildlife Conservation Trust Madagascar Programme as the coordinator of ecological monitoring and protected areas during the last 12 years. He is particularly involved in studying the role that can be played by local communities and stakeholders in conservation and monitoring towards better management of natural resources. His main concern is how to develop cost effective conservation programmes by integrating the community in efficient decision making. He is also interested in exploring the contribution that local community members can make in protecting ecosystem services in order to sustain social enterprises which could reduce poverty.

Current research

Under the supervision of Prof Kathy Willis, Dr Peter Long and Dr Richard Young, Herizo’s DPhil is looking at the effectiveness of community based conservation projects in conserving biodiversity, protecting ecosystem services and improving human wellbeing in Madagascar. Using Remote sensing techniques with satellite data from 1984 to 2012; village questionnaires, and household surveys with 6,540 households within 214 villages in 5 key conservation sites, Herizo is investigating whether the community based conservation projects implemented by Durrell Wildlife Conservation Trust Madagascar programme have improved the conservation of biodiversity and protection of provisioning ecosystem services, and enhanced people’s wellbeing. He is measuring important response variables such as Multidimensional Poverty Index, government records on school attendance, school attainment, health records, and DMSP OLS light at night to understand impacts of community based conservation projects on human wellbeing. He has used more than 2,000 Landsat images to understand forest loss, land cover change, suitable habitat for key species, habitat fragmentation and invasive plants. He also used AVHRR and MODIS data to measure rate of change of active fires and quantity of AGB, NPP forest, NPP croplands etc in each village. Additionally, Herizo is examining the cost effectiveness of the community based conservation approach by using Durrell financial records since 1997.
