Catching up with the Geospatial Revolution

Dr Catherine V Nnamani and Sylvia Ankamah at the GIS and RS Training Course

The Induction Workshop in Kenya for CIRCLE Cohort 2 Fellows made us understand the importance of integrating and taking advantage of training programs at our Host Institutions. The experience gained from the reports presented by Cohort 1 Fellows spurred us on to attend a two week training course on Geographic Information System (GIS) and Remote Sensing (RS). The training was an eye opener on what a researcher can do, enjoy and achieve with GIS. It was amazing, enriching and has built our capacity.

The training was organized by Space Applications and the Environmental Science Laboratory at the African Centre of Excellence in Obafemi Awolowo University, Nigeria. It is a World Bank Program/Flagship for collaborative research and development, and an innovation platform aimed at addressing Africa’s challenges relating to agriculture, environment, health, security, welfare, housing, disaster, transportation and industry using Satellite Spatial Data.

Knowing where and why things are located on the surface of the earth, their distributions and the patterns they create, as well as their dynamics are vital for sustainability and conservation. GIS is pertinent to almost all human activity regarding space. In today’s globalized world, where climate variability and change is increasing, and where people seek to make everything easier, we need GIS to simplify spatial and temporal analysis. About 90% of our daily decisions hinge on the question ‘where’. GIS brings the world to our palms, enabling us to make informed decisions about spatial issues. It makes evident patterns in life, distributions and activities, thus helping in the location of phenomena and giving insight into the dynamics of such phenomena. It aids in understanding the relationship between the physical and human environment, making easier the expressions of such relationships in maps and visual forms using satellite spatial data. GIS could be applied in many different aspects of Human and Environmental issues (Fig. 1).

The major aim of the training was to make environmental research easier, faster and timely by engaging individuals and companies whose activities have impacted, or have the potential to impact, the environment. The training was specifically focused on the basic concept of Geographic Information System, GIS Software’s, Primitive Spatial Analysis, Spatial Data Models and Map Design. Through the training our skills and capacity were enhanced in the following areas: 

  • How to manage and process environmental data from varied sources using raster/vector features, scripting, geoprocessing tools, cartography and projections.
  • We can now handle spatial analysis answering queries of accessibility, proximity and conservation using attribute features in AcrGIS
  • We can produce distributional maps of our study areas for our CIRCLE research.
  • Most importantly we want to share the good news that we were able to launch our first DRONE that captured spatial data on OAU, our Host Institution.

Our Joy knows no bound for participating in this training

CIRCLE Institutional Case Study: MOUAU

By Prof. Phillippa Ojimelukwe, Michael Okpara University of Agriculture Umudike (MOUAU)

When I saw the advertisement for the CIRCLE programme, I had little confidence that we would succeed in becoming a Home institution. I was uncertain we would be able to compete favourably with other well-established institutions; I also thought that the funders would be sceptical of lesser known institutions. Thankfully my fears were unfounded and the CIRCLE programme has been a revolutionary experience for Michael Okpara University of Agriculture, Umudike, Nigeria. We have benefitted both from the fellowship programme (with four fellows selected from MOUA) and the Institutional Strengthening Programme (ISP).  

The ISP has been transformative for our institution. We started with a detailed analysis of our institutional gaps and weaknesses. We aligned this with our university’s mandate - to lead the frontiers of research in agriculture for national development in a sustainable manner and to train high…

Research Uptake Discourse on Women, Entrepreneurship Development and Climate Change

By Dr Catherine Akinbami, Obafemi Awolowo University, Nigeria

In order to have a holistic approach, the economic, social and environmental issues which are interdependent aspects of a society must be considered within a unified framework so as to promote human welfare, especially in the rural areas. The consideration of the social dimension of climate change is important in order to ensure that human rights are not compromised as climate change impacts the fundamental security, lives, health and livelihoods of people, especially the most vulnerable. Also, greater consideration of the social dimension can enhance the effectiveness of mitigation and adaptation as well as the policies needed to drive them. 

On the 20th of April, stakeholders gathered at the Centre for Sustainable Development, University of Ibadan, Nigeria for a Policy Discourse on women, entrepreneurship development and climate change. The stakeholders comprised of policy makers from ministries (such as Women Affairs, Envi…

Kenyan Policy Makers Dialogue on Gender and Social Inclusion in the Climate-Smart Agriculture Strategy: Linking International and National Policy

By Catherine Mungai and Caroline Bosire
Kenya has made great headway in developing policies and strategies to respond to climate change across different sectors; most notably in agriculture. The agricultural sector is the driving force of Kenya’s economy and is also one of the sectors most sensitive to the impacts of climate change. The agricultural sector has been identified as a major source of greenhouse gas emissions, therefore necessitating the identification of measures through which the sector can mitigate climate change. Introduced by the Food and Agriculture Organization of the United Nations, climate-smart agriculture (CSA) is one such approach which aims to sustainably improve agricultural productivity, increase farmers’ resilience, reduce and/or remove greenhouse gas emissions, and support the achievement of food-security and development goals. To this end, through the Ministry of Agriculture, Livestock and Fisheries, Kenya has developed a CSA Strategy which will guide the …
