His research interests center on the application of Remote Sensing & GIS in Environmental Monitoring, Mapping, Urban Environmental Governance, Global Change, Food Security, Disaster Risk Reduction and Management as well as Applied Climatology. He devotes copious attention to climate change adaptation by poor, marginalized groups and people living on land; also on forest dynamics and response to climate variation and change as well as building resilience by vulnerable groups in urban milieu. He is a Research Affiliate, Institute of Environmental Health and Justice, Federal University of Technology, Owerri, Nigeria. In 2009, he was Tour Guide, BBC World Service Trust during a project on climate change impacts in eastern Nigeria. He was invited to the 1st and 2nd African Food Security Conference in 2013 and 2015 (see www.afsac2.aaknet.org); and to the International Conference on Applied Geo-informatics for Society and Environment in 2011 in Nairobi, Kenya. In 2009, he represented the User Community at the Third African Leadership Conference on Space Science and Technology for Sustainable Development in Algiers, Algeria, among others. He is Rapporteur of the Nigeria National Branch (NNB) of the Ecosystem Based Adaptation for Food Security in Africa Assembly (EBAFOSA), secretariat@ebafosa.org, www.ebafosa.org. Journal Editor, Journal of the Nigerian Cartographic Association. He is a member of Association of Nigerian Geographers, Cartographic Association of Nigeria, Nigerian Environmental Society as well as the Nigerian Institute of Management.
