advancing sustainable agriculture: renewable energy integration and policy implications for irrigation in nigeria – a systematic review

This research review explores the application of renewable energy sources, such as solar, wind, and biomass, in irrigation practices throughout nigeria. following the prisma (preferred reporting items for systematic reviews and meta-analyses) standard, we identified 295 articles published between 2010 and 2023, with 65 articles reviewed specifically for insights into energy transitions in nigerian irrigation, the impact of sensor design and technology on irrigation automation, and the influence of government policy on renewable energy adoption in irrigation. synthesizing findings from diverse studies, we discuss the benefits, limitations, and performance assessments of these renewable energy systems. while recognizing their potential to reduce environmental impact and operational costs while promoting sustainability, the review highlights discrepancies in study outcomes, particularly concerning the effectiveness and scalability of automated irrigation systems. additionally, we examine the pivotal role of government policies in shaping the development and uptake of renewable energy technologies in agriculture. the review underscores the necessity of standardized evaluations and supportive policies to facilitate the widespread adoption of renewable energy for irrigation in nigeria.
