Cassava farming, a cornerstone of agriculture in Nigeria, is facing unprecedented challenges due to climate change. These changes threaten the cassava harvest, impacting food security and livelihoods. As the effects of climate change advance, understanding its impact on cassava production becomes crucial for farmers aiming to sustain and improve their yields amidst these adversities.
This article delves into strategies for adapting cassava farming to climate change, including the embrace of technological innovations and the support of community and governmental efforts. Highlighting successful case studies, it offers a roadmap for resilient cassava plantations in Nigeria, ensuring the sustainability of this vital crop in the face of changing global climate patterns.
Understanding Climate Change Impact on Cassava Production
Climate change significantly affects cassava farming in Nigeria, impacting various factors crucial for the crop’s growth and yield. Here’s a closer look at how these changes influence cassava production:
- Arable Land and Rainfall: The availability and quality of arable land, along with changes in rainfall patterns, play a significant role in cassava yield. Increased rainfall variability and temperature fluctuations have been linked to a decrease in income and daily calorie intake among farmers, underscoring the importance of understanding and adapting to these changes.
- Greenhouse Gases Impact: Greenhouse gases, including C2O, nitrous oxide, and methane, have a long-term significant impact on cassava yield. Methane, in particular, causes the most damage, highlighting the need for strategies to mitigate these effects.
- Dual Impact of Climate Variables: Temperature, rainfall, humidity, number of rainy days, and sunshine hours are key climate variables that affect cassava production. These variables have dual impacts, influencing cassava yield both positively and negatively. For example, cassava thrives in warm temperatures between 77°F and 86°F but can be damaged by extreme temperatures, especially frost. Similarly, adequate and well-distributed rainfall supports optimum growth, yet changes in rainfall patterns, such as prolonged droughts or excessive rainfall, can negatively impact production.
Understanding these impacts is crucial for developing effective adaptation strategies to secure cassava yield and food security in Nigeria amidst climate change challenges.

These technological strides not only improve cassava yield and quality but also offer solutions to longstanding challenges like genetic resource management and post-harvest losses, marking a significant leap forward in cassava farming practices.
Community and Governmental Support in Adaptation Efforts
In Abia State, Nigeria, cassava farmers encounter several barriers to adapting to climate change, including:
- Limited Resources: Access to farmland and farm inputs is scarce, alongside a notable lack of credit facilities.
- Knowledge Gap: There’s a widespread lack of awareness about coping mechanisms and resilience strategies against climate change impacts.
- Infrastructure and Support: The non-availability of weather forecasts, government’s slow response to climate change effects, and the high cost and limited access to labor further exacerbate the challenges.
To combat these issues, the following measures are recommended:
- Enhanced Training and Awareness: Conduct regular training sessions on climate change and its variability. This includes making meteorological data readily accessible to farmers.
- Improved Cassava Varieties: Ensure the steady availability of improved cassava varieties that are more resilient to climate change.
- Policy and Land Use Review: A revision of the Land Use Act of 1990 could facilitate increased access to land for farming activities.
In Kenya, government and community efforts have shown significant positive impacts on cassava farming through:
- Research and Development: Investment in research for developing pest- and disease-resistant cassava varieties.
- Capacity Building: Implementing training programs and workshops on modern farming techniques and value addition.
