Promoting Ecosystem Conservation and Food Security through Sustainable Harvesting of Edible Caterpillars in Kanchibiya District, Zambia

Abstract

Insects play a vital role in enhancing food security and improving the livelihoods of rural communities. This study focused on the identification of caterpillar harvesting practices in Zambia, particularly in Chief Kopa’s village, Kanchibiya District, Muchinga Province, where the caterpillars of Gynisa maja and Gonimbrasia belina play a crucial role in food security. A mixed-methods approach was employed, utilizing face-to-face interviews and self-administered questionnaires to capture both qualitative and quantitative insights. Quantitative data, including caterpillar harvesting amounts and correlations with tree destruction, underwent statistical analyses, including ANOVA and post-hoc Tukey's HSD tests. The Chi-square test explored gender distribution across research sites. Qualitative data from open-ended questions during interviews underwent thematic analysis. The study sampled 100 respondents from six areas, and the results revealed significant differences in caterpillar harvesting amounts among villages. Post-hoc tests identified specific pairwise differences. The findings indicated that traditional harvesting methods persisted, with limited adherence to rules. A significant positive correlation was observed between caterpillar harvesting practices and evolving trends such as increased harvesting intensity, changes in harvesting methods, and environmental impact and tree destruction (p=0.001, r=0.917). The study contributed valuable insights into past caterpillar harvesting practices, proposing conservation strategies for enhanced food security and sustainability. The study proposes a multifaceted approach to balance ecosystem conservation with food security in Kanhaiya District, emphasizing the importance of sustainable caterpillar harvesting. Recommendations include developing community-based sustainable harvesting guidelines, such as rotational zones and harvest limits, alongside education programs to raise ecological awareness. It advocates for diversifying livelihoods and food sources to lessen dependence on caterpillars, ensuring gender-inclusive participation in these initiatives. Monitoring and further research are essential to adapt strategies effectively. These measures aim to preserve the ecosystem, ensuring the caterpillar's role in food security and offering socioeconomic benefits by fostering community resilience and reducing food insecurity vulnerabilities
