Climate Change Awareness and Impact in Ecological Zones of Tropical Rainforest and Guinea Savannah of South-Western Nigeria

2026Open accessOsun State University

In plain language

An assessment of climate change awareness and environmental impacts was conducted across the Tropical Rainforest and Guinea Savannah ecological zones of south-western Nigeria. Covering five states, namely Ekiti, Ogun, Ondo, Osun, and Oyo, the research gathered primary data from 371 survey and interview respondents alongside geographic information system analyses. The findings revealed a high awareness rate of 95.45 percent, which remained consistent across both ecological zones. Factors shaping this awareness include available information sources, educational attainment, and cultural background. Observed climate impacts span environmental degradation, economic difficulties, and adverse consequences for the physical and health conditions of local populations. To address these ongoing challenges, recommendations focus on expanding public awareness initiatives and incorporating climate change education across all educational levels.

Key takeaways

  • Climate change awareness reached 95.45 percent and was uniform across both the Tropical Rainforest and Guinea Savannah zones.
  • Levels of climate awareness are driven by information sources, educational attainment, and local culture.
  • Climate impacts in south-western Nigeria affect the environment, the economy, and the physical health of the population.
  • Recommended interventions include public awareness campaigns and the integration of climate change education at all levels.

Why it matters

Understanding regional climate awareness is vital for designing effective adaptation strategies in ecologically sensitive areas. Because climate change directly threatens biodiversity, economic security, and public health across tropical rainforests and savannahs, confirming high public awareness allows policymakers and civil society organisations to focus on targeted educational interventions and actionable resilience programmes rather than basic recognition alone.

Abstract

The impact of climate change on the Tropical Rainforest and Guinea Savannah vegetation zones is a global and regional concern due to their high biodiversity and role in regulating carbon, water, and nutrient cycles. Recent environmental changes are linked to rising atmospheric carbon levels caused by human activities like deforestation. Evidences of climate change have been seen across the atmosphere, oceans, cryosphere, and biosphere, indicating global warming. These changes include temperature extremes, heavy rain, floods, droughts, storms, and other climate extremes. This study assessed climate change awareness and impacts in the Rainforest and Guinea Savannah zones in southwestern Nigeria, using a mixed-method approach, to determine the level of awareness of climate change impact in the two ecological zones. Primary data were obtained through surveys and interviews of respondents A purposive sampling technique was used with Taro Yamane Formulae (TYF), to determine sample size and a sample of seventy-seven (77) respondents selected from each of the five study States: Ekiti, Ogun, Ondo, Osun, and Oyo. The sampling targeted participants who best represent the population with total of 371 respondents. Climate data were analyzed with GIS tools (ArcGIS Pro), and Fisher’s exact test examined hypotheses. The study revealed that awareness levels are similar across the ecological zones with 95.45%. The level of awareness is created by sources of information, education level, and culture. Climate impacts affect the environment, economy the physical, and health life of the populace. The study recommends public awareness campaigns and integrating climate change education at all levels.
