Prof. Cecilia Moraa Onyango is a board member of OCA and a Senior Lecturer at the Department of Plant Science and Crop Protection, University of Nairobi. Prof. Onyango earned her PhD from Wageningen University, the Netherlands; and both her MSc. in Horticulture and BSc. in Agriculture from the University of Nairobi.

She has over 15 years of experience in a broad range of  agricultural practice and related sustainable development  areas which include; crop production and postharvest handling with a focus on production environment and food safety; conservation of biodiversity; eco-efficient bio-resource management; stress physiology and temperature-based modulation of plant growth and development; grading and standards; and participatory farmer and end-user technology evaluation, selection and adoption.

Her expertise and experience continues to impact various levels of value chain stakeholder interests including; policy, strategy, implementation, monitoring and evaluation and related skills transfer. Additionally, she has consultancy knowledge, skills and expertise on systems intensification and market led sustainable socio-economic development.

Prof. Onyango has proven leadership and management skills and experience: She has provided leadership in executing various projects to provide information on crop production practices and food quality which include; agroecological intensification techniques for climate change adaptation and mitigation; and consumption trends and the safety of foods sold and consumed in Kenya and the Eastern Africa Region.

Prof. Onyango is a firm believer in an engendered development approach to ecosystem health and sustainability; she believes that there is a strong linkage between soil health, crop production environment and practices, and the quality and safety of the harvested product, which product is ultimately consumed for nourishment to achieve food and nutrition security and ultimately a sustainably improved quality of health and life.

Ms. Mairura is the OCA Associate for Governance and Policy. Her experience which spans over 10 years includes knowledge and experience in Leadership and Governance. Her educational and academic background includes qualifications in Sociology from York University, in Canada and Masters in Public Administration from the University of Liverpool, UK. She brings on board experience in public sector management, public finance, policy analysis, governance and related capacity building.

Ms. Mairura’s experience spans East Africa, North America and UK, with rich country experiences in Kenya and Canada, in particular. Her over 10 years experience includes technical assistance and support to the Federal Government of Canada and Government of Kenya, at national and sub-national levels, on legislation, governance oversight and accountability frameworks for ‘Good Governance’ and policy; this has included alignment of existing legislation, following Kenya's transition to a devolved system of governance, to the County governments systems.

She has been involved in Health Systems Strengthening applied research and implementation projects which support public sector organizations and non-governmental organizations to adopt tools and best practices geared to; improving quality, increasing access to, and expanding demand for health services across all levels of the agro-health development value chains, within the context of a systems thinking framework.

Towards that end, she advocates for increased investment in “One Health” governance and related evidence to inform policy advocacy in mainstreaming the “One Health” approach; The “One Health Concept” is the unity of multiple practices that work together locally, nationally and internationally to help achieve optimal health for people, animals and the environment – the triad embraces environmental health, animal health and human health policies, all anchored on policies that promote soil health and soil regeneration: A paradigm shift from the current industrial-chemical agricultural model to an agro-ecological food production and consumption system, which includes organic foods, is the way forward.

Ms. Mairura advocates for and champions collaborative governance approaches and evidence based leadership: These approaches motivate, inspire and promote relationships and partnerships towards attainment of optimal conditions for: “People, Planet and Profits”.

Statement of purpose

Prof Wahome is the founding chairman of OCA and a professor of Livestock Production systems at the University of Nairobi where he has been teaching for the last thirty years. He has veterinary background having been trained at the University of Nairobi, Alberta and Guelph Universities in Canada. His research has focused on healthy commercially viable agricultural systems. Currently he is the Kenyan ProGrOV project manager. ProGrOV seeks to improve productivity along organic value chains through participatory field and on station research that yields specialized knowledge and skills needed to produce, promote and avail healthy food products to organic consumers.  The project builds capacity for research and teaching while seeking solutions for challenges of developing organic value chains in Eastern Africa Region.

He believes on the importance of nature and cultural experiences with the abilities to give rise to sustainable systems that support enterprise and produce innovation based on indigenous and traditional knowledge and practices. Nevertheless, he is convinced of the need for continued learning: within production, processing and distribution networks; local and global - hence his commitment to teamwork.  His approach to activities is founded on the principle that quality is an attitude built on character, with endeavour to continuously consult with people to ensure fulfilment of their desires.   

The greatest enjoyment that people can have is derived from food. When food is scarce, almost anything will do: and it is received with gratitude and a feeling of satisfaction.  However, not just any food will provide necessary health for enhanced enjoyment of life. The body’s physiological mechanisms soon demand better and more balanced food to continue functioning. There are levels of functioning that are possible with ordinary low quality foods. However, human wellbeing demands that good quality and safe foods be made available and that people have healthy lifestyles in healthy environments.  Prof Wahome relates need for good policy, strategies and implementation knowledge, skills and practices for pertinent health and safety issues, within the broader context of an eco-friendly and sustainable development agenda.

Prof Wahome insists that eating of good quality, safe and organic foods makes sense to anyone with a caring spirit – whatever the concern. For those who worry about making money, there are numerous opportunities ranging from input manufacturing and distribution to product processing and consumption. Those who care about people realize fulfilment from the fairness principle of organic production. Environmental responsibility is addressed through ecologically balanced production practices that emphasize nutrient recycling, waste reduction and reuse. Organic production and consumption also brings people who care together; providing forums for discussion on what we can do to make our lives more meaningful and healthier.

He says “live right, eat well, care and discuss… and you will have a fulfilled life’.
