The study looked at how climate change affects sweet potato farming in Goroka, PNG, by examining changes in rainfall and temperature, collecting farmers' views on climate impacts, and comparing these findings to understand if climate change really harms their crop production.
This study aimed to investigate the specific physiological and yield responses of sweet potato or kaukau (ipomea batatas) species cultivated in Goroka, PNG, to simulated or observed climatic variations associated with climate change, including altered rainfall patterns and temperature extremes. To achieve this, we also collected qualitative data through farmer interviews to integrate local knowledge on perceived climate impacts and traditional coping mechanisms.
Hypothesis/Research Question
Null hypothesis (H0):
"Climate change does not affect kaukau production in Goroka, PNG as farmers attribute changes to other factors like land degradation."
Alternative hypothesis (H1):
"Climate change (specifically changes in rainfall patterns) has a significant negative impact on kaukau production in Goroka, PNG, as reported by farmers in the qualitative questionnaire data."
