Firstly, the study is based on observational data, making it difficult to establish causality between water availability and Robusta coffee bean yield.
Secondly, the study only focuses on water availability, ignoring other factors that may affect yield, such as soil quality, pest and disease infestation, and climate variability. Therefore, future research may consider conducting experimental studies to establish causality between water availability and Robusta coffee bean yield while controlling for other confounding factors. Additionally, research may consider investigating the impact of water management practices on the coffee value chain’s sustainability and resilience to climate change.
Comparison with Previous Studies
The current study investigated the relationship between water availability and Robusta coffee bean yield. The overall findings indicate that when water availability is increased, there is a corresponding increase in coffee bean yield. This finding contrasts with some previous studies, which have suggested the relationship between water availability and coffee bean yield is more complex. Specifically, some studies have found that excessive water can actually lead to decreased yields, while other studies have suggested that moderate water stress can result in higher yields.
Despite these differences in findings, the current study provides some important contributions to the existing literature. For example, the study used a more nuanced measure of water availability than many previous studies, which relied solely on precipitation data. In contrast, the current study used a combination of precipitation data and soil moisture data to create a more accurate picture of water availability. Additionally, the current study used a large sample size that spanned multiple years, which strengthens the reliability of the results.
Overall, while the current study provides valuable insights into the relationship between water availability and coffee bean yield, there are still some limitations to the findings. For example, the study was conducted in a single region, and the findings may not be generalizable to other regions. Additionally, the study did not examine the interactions between water availability and other factors such as temperature and soil quality, which may also play a role in coffee bean yield. Further research is needed to better understand these complex relationships and to help coffee farmers optimize their practices to maximize yield.
