Adoption of climate-smart microgardening practices for root and tuber crops in urban households: A case of Abia state, Nigeria

This study examined the adoption of climate-smart microgardening practices among urban households, with a focus on the cultivation of root and tuber crops, specifically yam, cocoyam, and cassava. The research highlights innovative approaches to urban farming that align with sustainable development goals in light of climate change. The study surveyed 33 households that practice microgardening in Umuahia and Umudike, Abia state, using a snowball sampling technique. Among the respondents, 57.6% grow yams, while 9% cultivate cocoyam and 3% cassava in mainly bags and tyres. Key findings indicate that microgardening reduces household food expenses (mean = 3.64), and promotes the adoption of climate-smart agricultural practices, such as zero use of inorganic fertilizer (mean = 3.15), organic pest and disease control (mean = 3.36) and the recycling of cultivation materials (mean = 3.15). Social and economic benefits include increased access to fresh and nutritious food (mean = 3.93), improved interaction with neighbors (mean = 3.42), and opportunities for skill development (mean = 3.67). However, challenges such as limited space, difficulty in watering during dry seasons, and the high cost of inputs persist. Regression analysis revealed that socioeconomic factors, like age (10%) and income (5%), positively influenced the adoption of climate-smart practices, while experience in microgardening (5%) has a negative impact on adoption. This study underscores the importance of leveraging climate-resilient technologies to enhance the sustainable management of root and tuber crops in urban environments, contributing to food security, poverty alleviation, and economic development.
