Climate Change Debates: whose report will you believe? A field report from southwestern Nigeria

There are several scientific debates on climate change and its impacts on man and the physical environment. The evidence used in these debates has shown that climate change is a global issue and that one small attempt may not significantly curb its extreme events and their impacts. The majority of the evidence used is, therefore, based on projections from climate change models. However, climate change models and scenarios for West Africa have some challenges. For example, while some models of precipitation suggest increases, some predict decreases and other studies, such as a recent report from IPCC, reveal uncertainty about future rainfall patterns. Another set of debates on climate change are those around adaptation amongst rural people, especially smallholder farmers in Africa. Key issues around climate variability/change impacts, awareness and adaptations are not only restricted to climate scientists, but also a big threat facing rural farmers. Some scientists, however, notice that local farmers’ knowledge of climate change is insufficient for rigorous evaluation of planned adaptation.

Based on this assumption, my CIRCLE-funded research set out with the main objective of testing whether farmers’ perceptions of climate change/variability are consistent with scientific analysis. Using ethnographic and meteorological analysis, the study aims to compare the climate change perceptions of both crop and livestock farmers with historical meteorological analysis. The field work is centered on three research questions: (1) has rainfall and temperature varied/changed in the study area over the past three decades?; (2) to what extent do rural farmers in Southwestern Nigeria perceive changes in climate?; and (3) how do rural farmers’ perceptions of climate change compare with the trends from historical climatic data? The field work was conducted in Akeredolu, Alaguntan, Faforiji, Igboho,  Igbope,  Ilora, Iseyin, Odemuyiwa Kisi and Shaki.

What is obvious from observations in the field is the close link between climate and farming activates in the region of study. This is because the majority of farming practices are rain-fed. During in-depth interviews and focus group discussions the majority of farmers claimed that they “observe that rain falls for a short time and the duration is limited compared to the past 30 years”. The majority of the farmers had experienced prolonged dry spells and the recurrence of drought.  Nearly all the farmers perceived that the onset of rainfall is much later recently than over the last 30 years. They had also noticed that rainfall now ceases half way into the end of the normal wet season months. Most of the farmers claimed that the overall impacts of climate change on both crop and livestock are estimated to be highly negative, much more on maize, yam, and rice and unexpectedly high on cattle, chickens, pigs, sheep and goats.

As yet, we have little idea of how farmers’ perception of climate change closely mirrors the climatic trend from the scientific meteorological analysis. The major objective of the next stage is to test whether farmer’s perceptions of climate change/variability are consistent with climatic trend analysis. The rural farmers awareness of climate change, its impacts and their speciļ¬c adaptation measures, will be seen as science-driven assessments for appraising the trend of rainfall and temperature during rainy and dry season;  patterns of onset; and length of rainy season with their seasonal variability.


  1. Congratulations Dr. Ayansina Ayanlade

  2. Congratulations Sina, excellent read.

  3. Good job Sir. Congrats to Dr Ayanlade. Extension research methodology can really help us to understand issues regarding CC from farmers perspective.Please where can we get the full publication. I need it as a case study for my Credit Seminar for my PhD (Agricultural Extension) here at Indian Agricultural Research Institute, New Delhi, India. I am working on Ethnography studies for Extension Research

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 …
