About Mrs Jacinta NYAIKA
I am a trained specialist in agri-food systems, food safety, and marketing, with practical experience in production and post-harvest handling, processing, and value addition of Horticultural crops, seed systems, value chain analysis, adaptation to climate change, and Monitoring and Evaluation of Gender and Agricultural projects. I have over ten years of experience in conducting consultancy work, particularly in: • Estimation of postharvest losses in fruits and vegetables • Conducting situation analysis in the post-harvest supply chain of fruits and vegetables • Conducting needs assessment for production and postharvest handling of horticultural crops among farmers • Designing and implementing research projects to reduce postharvest losses in fruits and vegetables. • Planning and delivery of training in production and postharvest handling, seed systems of horticultural crops and climate change-related topics. • Development of production manuals/modules for field extension workers, smallholder farmers and students. • Monitoring and Evaluation of Agricultural and Gender Studies Other skills include proficiency in Microsoft Office (Word, Excel, PowerPoint), SPSS, Genstat, R-Studio, and Quantitative and Qualitative Evaluation approaches, with a focus on DAC criteria, principles, and standards.
Research Interest for: Mrs Jacinta NYAIKA
Postharvest physiology and handling of horticultural crops
My research focuses on the postharvest physiology and handling of horticultural crops, with particular emphasis on reducing losses, enhancing quality, and ensuring food safety across the value chain. I am interested in: • Physiological responses of fresh produce to environmental stress during storage, transport, and marketing. • Innovative handling and packaging systems that extend shelf life while maintaining nutritional and sensory quality. • Climate-smart and resource-efficient postharvest technologies, tailored to smallholder and emerging markets. • Food safety and quality assurance frameworks, including cyanide safety in cassava and standards for fresh produce. • Market economics of postharvest systems, linking scientific innovation with practical adoption and policy impact. My work integrates applied physiology, sustainable technologies, and market-driven approaches to strengthen horticultural value chains and contribute to resilient, eco-friendly food systems.
Toxicology of fruits and vegetables from contaminants
I am deeply engaged in the toxicology of fruits and vegetables, with a focus on understanding how contaminants influence both plant systems and the human food chain. My interests include: • Residual pesticide toxicology, examining how chemical residues accumulate in produce and their implications for human health and food safety. • Environmental contaminants in horticulture, studying how toxins absorbed from waste, industrial effluents, and mining activities affect plant physiology, growth, and development. • Nutritional quality under stress, investigating how exposure to pollutants alters the nutritional composition and safety of fruits and vegetables. • Risk assessment and mitigation strategies, developing science-based approaches to reduce toxicological risks in horticultural value chains. • Policy and standards for food safety, linking toxicological research to regulatory frameworks and sustainable agricultural practices. My work bridges plant physiology, environmental toxicology, and food safety, aiming to safeguard consumer health while promoting resilient and sustainable horticultural production systems.
Cultural traditions in shaping local food systems
I am building a research portfolio in cultural traditions within food systems, exploring how heritage, identity, and local practices shape agricultural production, consumption, and sustainability. My interests include: • Indigenous food knowledge and practices, examining how traditional methods of cultivation, preservation, and preparation contribute to resilience and biodiversity. • Cultural dimensions of food safety and nutrition, understanding how beliefs, rituals, and community norms influence dietary choices and health outcomes. • Integration of cultural heritage into modern food systems, identifying ways to harmonize traditional wisdom with contemporary science and technology. • Socioeconomic and policy perspectives, analyzing how cultural traditions affect market dynamics, value chains, and food governance. • Sustainability and identity, investigating how food traditions reinforce cultural identity while promoting environmentally responsible practices. This portfolio seeks to bridge science and culture, highlighting the role of traditions in shaping sustainable, inclusive, and resilient food systems.
