Sustainability assessment of organic and conventional agricultural farming systems in Kenya: The cases for Machakos, Murang’a and Kirinyaga Counties

Thesis abstract

Sustainable production systems offer Africa vast opportunities in terms of improving food and nutrition security, snowballing local access to food, bringing degraded land back into production, building the resilience of farms to climate change, especially to water stress, and protecting biodiversity and ecosystem services through their sustainable use. Agricultural activities have been the driving force in sub-Saharan economies for many years. Appropriate spatial level factual information, which can guide policy-makers in their decisions while reflecting tradeoffs between the ecological, economic and social dimensions of sustainability to aid in evidence based research strengthens the farming system. In the case of sustainable agriculture, a suite of knowledge, skills, practices, technologies and organizational arrangements exists to enable farmers to practice sustainable intensification. In Kenya, there is limited information on economic benefits of organic production that can be used to legislate on policy, decision makers and other regulatory agencies on how to promote the growing sector and organic practices. The study, therefore, was set to contribute to the knowledge gaps in aid of better decision making in policy sector and at farm level in Kenya on profitability, economic resilience and environmental sustainability of organic versus conventional farming systems. The study will cover 864 households with about 270 having different degrees of variation of organic farming and targeting 401 female respondents. The dynamic nature of sustainability requires not just one set of approaches or tools but a variety of options to verify the multiple degrees of farms and decisions farmers make in the farm. Econometric modelling and statistical analysis in R and SPSS will be used to carry out Cluster analysis, testing differences, Data envelopment analysis (DEA), stochastic frontier analysis and regression models and farm optimization models. Data interpretation on the performance of organic vs. conventional agricultural systems that is profitability and economic resilience, and tradeoff and synergies between environmental sustainability and economic resilience at farm level in Kenya will be documented for policy users as well as the farmers.


Key words: sustainability assessment, profitability, economic resilience, environmental sustainability and organic and conventional farming systems
