摘要：The underperformance of the communal sector, coupled with reduced government subsidies driven by macro-economic
instabilities in Southern Africa, has led to persistent food insecurity among communal households. The main objective of this
study was, therefore, to assess the potential of wetland maize production in improving food security in communal areas of
Zimbabwe. A survey approach was employed. Structured questionnaires, semi structured interviews, and focus group
discussions were used for data collection. Multiple regression analysis was used to determine the impact of wetlands on
maize yields and gross margin analysis to compare the returns to maize production for wetland farmers and formal irrigators.
Wetlands were found to have a significant (P<0.05) impact on maize yields. Gross margins for wetland farmers were
significantly (P<0.05) higher than for irrigators. State and non-state actors can collaboratively intervene in the provision of
technical knowledge on sustainable utilization of wetlands to improve household food security.
