In the last two paragraphs of your introduction, the objectives of the study are presented alongside the research gaps and the significance or justification of the work. However, when it comes to articulating research gaps, many students fall into a familiar but weak pattern of writing statements such as “limited studies have examined this”, “there is no literature on this topic”, or “there is currently no knowledge in this area”. In reality, these claims are often inaccurate. Research is ongoing across the world, day and night.
During my time in China and Taiwan, I witnessed firsthand how intensive and continuous research can be. At the National Radiation Research Center in Taipei, part of the National Institute of Radiation Research, laboratory work ran nonstop, 24 hours a day. Scientists from all over the world converged there, working and finding solutions to various problems confronting mankind. Laboratories were filled with prepared protocols, displayed processes, and validated results. This experience reinforces a simple truth: people are working, and knowledge is constantly being produced.
Therefore, identifying a research gap does not mean claiming that nothing has been done. Rather, it requires a careful and honest engagement with existing literature to understand what has been done and what has not. There is nothing entirely new under the sun. What you are investigating may already exist in some form, but novelty lies in how you carve your study to suit a specific context, question, or methodological approach.
The strategy begins with a thorough reading of the literature. Particular attention should be paid to the objectives, methodologies, findings, and conclusions of previous studies. These sections provide the most fertile ground for identifying gaps. This is what I was taught at Kenyatta University in Nairobi. I do this, and I teach my students this style. It can be adapted to suit your style too, if you so wish.
One practical approach is to organise the literature into a structured table. For example, the table may contain columns for study number, study title, objectives, methodology, key findings and conclusions, and gaps identified.
As each study is reviewed, it is entered systematically into the table. The gaps can emerge from various aspects of the study, including the objectives pursued, the methods applied, the conclusions drawn, or even the limitations acknowledged by the authors. After reviewing several studies in this structured manner, the identified gaps can then be synthesised and rewritten in a coherent narrative form. An example is given below from my research area:
"In the context of mine land remediation, many studies have examined land tenure systems. However, a critical gap may lie in understanding how land tenure systems influence climate change policies and outcomes. For example, Lisa et al. (2022) examined factors contributing to the failure of land reclamation efforts, highlighting the neglect of land tenure issues. While their arguments are compelling, a closer look at their methodology reveals a strong reliance on qualitative interviews with farmers and landowners. Although such an approach provides valuable insights, it may not be sufficient on its own. Addressing such a complex issue may require a quantitative or mixed-methods approach that integrates spatial analysis, policy modelling, and socioeconomic data. Similarly, another author may have explored the same thematic area and offered useful solutions, yet failed to capture additional dimensions such as temporal variability, institutional dynamics, or ecological feedback mechanisms."
This strategy should be repeated across several studies until the remaining gaps are clearly defined.
At this point, your own study naturally enters the discussion. Your objectives respond directly to the identified gaps. Your methodology addresses the methodological limitations observed in previous studies. Your hypotheses emerge from unanswered questions in the literature. You then articulate how your approach tackles the problem in a more holistic and integrated manner.
Finally, you provide a clear justification for why your approach is novel and ideal, followed by one or two concise statements explaining the significance of the study to the field, sector, or policy domain under investigation.
In doing so, you establish research gaps rigorously, expand the scope of inquiry, and present a study that is both intellectually grounded and genuinely novel, rather than one that merely repeats generic claims about limited literature.
