The rapid growth of the global population, particularly in urban areas of developing countries, has led to an increase in energy consumption and environmental challenges, necessitating the search for sustainable energy solutions. Biomass energy, derived from organic materials such as agroforestry residues, presents a promising avenue for addressing these challenges by offering a renewable and potentially carbon-neutral energy source. This paper explores the potential of agroforestry residues as a sustainable biomass energy source, examining the availability, technological conversion processes, environmental impacts and socio-economic benefits. Agroforestry, a land use system integrating trees and crops, generates significant residues that can be transformed into energy, thereby contributing to rural development, energy security and climate change mitigation. The review highlights the challenges and opportunities associated with biomass energy production, including sustainability concerns, technological and logistical hurdles and the need for supportive policy frameworks. Successful case studies underscore the feasibility and benefits of converting agroforestry residues into bioenergy, emphasizing its role in a circular economy and its contribution towards achieving renewable energy targets and sustainability goals. The paper concludes that, with appropriate management and technological innovation, biomass energy from agroforestry residues can play a pivotal role in the global transition to renewable energy, enhancing environmental sustainability and socio-economic development.
