Overview

Ethno-ecological survey reveals distinct cultivation practices and climate change impacts across tiger nut producers, highlighting needs for climate-resilient crop breeding.

Key Points

  • Document and compare indigenous knowledge on tiger nut (Cyperus esculentus) uses, cultivation systems, and farmer perceptions of climate change impacts across two contrasting climatic zones in Togo.
  • Surveyed 206 tiger nut producers from six ethnic groups across 26 villages in the Savanes (Sudanian climate) and Plateaux (Guinean climate) regions from July to September 2023 using snowball sampling and participatory rural appraisal methods.
  • Evaluated associations between regional sociodemographic variables, cultivation practices, and climate change perceptions using descriptive statistics, Fisher's Exact Test, chi-square tests, and multinomial logistic regression.
  • Producer demographics and land allocation diverged significantly: Savanes producers were 75% male with farm sizes ≤0.25 ha, whereas Plateaux producers were 84% female, with 58% cultivating >0.25 ha.
  • Producers identified seven distinct uses—with traditional beverage preparation, soil fertilization, and livestock feeding reported exclusively in Savanes—while primary cultivation barriers were pest attacks in Savanes and harvesting difficulty in Plateaux.
  • Farmer perceptions of climatic shifts and production impacts differed significantly between climatic zones (P < 0.001), with producers linking erratic rainfall and droughts to seedling desiccation, reduced yields, and smaller tubers.
