Overview

Randomized trial assesses the impact of climate parameters on food production in Togo, suggesting adaptation strategies are needed.

Key Points

  • This study aims to analyze how seasonal changes in climate affect food crop yields in the western Plateau region of Togo.
  • Analyzed climatic data from 1991 to 2020 at six weather stations using RStudio 4.4.0.
  • Employed ordinary least squares regression to assess the relationship between climate and food production.
  • Integrated daily rainfall data and available soil water to evaluate rainy season characteristics.
  • Transition from bimodal to monomodal rainfall regime with 4–5 month dry and 7–8 month rainy seasons.
  • Maximum temperature positively influences cowpea yields (p = 0.0079), but negatively affects cassava (p = 0.00013) and rice (p = 0.050).
  • Significant spatial variability in precipitation was noted during the long rainy season.
