Urban Agriculture and Environmental Quality in A Fast-Growing Tropical City of Uyo, Nigeria
Main Article Content
Abstract
This study aimed at identifying effect of urban agricultural practices on environment of the study area. Sample size consisted of 192 farmers selected through multi-stage sampling technique from the farmers in the study area. Survey was carried out using participatory approach on farmers with the use of questionnaire. Results were analysed to identify impact of practices on soil quality using farmers’ perspectives. Conventionally, impact was identified using conventional agricultural assessment framework. The relationship between farming practices and soil quality was established by correlation analysis. Crop production practices identified by farmers were the
use of hormones, pesticides and fertilizer usage, clearing and stubble burning, tillage practices, irrigation and reduced fallow period. From conventional soil analysis, low organic matter content and high acidity are indicators of low fertility. Farmers’ perception of impact of farming practices on soil quality correlates well with soil quality analysis. The study recommended the need for farmers’ participation in formulation of agricultural policies in order to articulate their opinion. Also, conservation tillage that is adapted to soil type and topography as well as farming policies that include financial reward to farmers that comply with environmental standards is recommended. Framework for assessing ecological status of water resource should inculcate incentives and institutional capacities. Overall, extension service for awareness creation through demonstration should be inculcated.
