Climate changes in Cameroon have led to disruption of the agricultural calendar and declining productivity. In northern regions, droughts and flooding threaten food security by impacting agriculture. Higher temperatures and fluctuating rainfall, combined with population growth, pose a serious risk to food supplies by reducing crop yields and agricultural output over time. A study analyzed how climate uncertainty affects farmers' investment and production decisions, and found that income is highly responsive to changes in rainfall and temperature. It also took farmers significant time periods to fully adjust crop levels, capital, labor, and fertilizer use in response to uncertainty and market changes.

1. ►In Cameroon, in recent years, climate changes cause
instability in rainfall leading to disruption of the agricultural
calender and a substantial decline in agricultural
productivity
►In the north of the country in the sahel region, these
climate variabilities cause desiccation of rivers, west
drought surface water, and rising sea coast whith flooding
►High temperatures and current fluctuations in
precipitation, combined with population growth, are a real
and permanent threat to food security trought their impact
on agriculture in Cameroon
►Rising in temperature causes lower yields of desirable
crops and the proliferation of bad harvests in the short run
on the one hand, and a substantial decline in agricultural
production in long run in the other hand
►To understand and quantify the link between climate
and agriculture
►To analyze how the expectations of farmers on climate
change affect investment and production decisions and
the process of adjusting factors of production
►Ricardian Approach
►Stochastic dynamic duality approach
♦The income elasticity of farm income compared to the
change in precipitation and temperature are high.
♦The marginal effects of rainfall and temperature on farm
household incomes are high.
♦Under uncertainty and market price change,
Cameroonian agricultural farmers take about two and a half
years to fully adjust the desired level of their crops, about
24 years for capital, one and half year for labour and about
nine months for fertilizer to their optimal level.
