In the heart of Pakistan, a pressing issue flows beneath the surface, one that could reshape the country’s economic landscape and energy sector dynamics. A recent study, led by Saqib Munir from the Department of Economics at the NUST Institute of Peace and Conflict Studies (NIPCONS) in Islamabad, has shed new light on the complex interplay of factors driving water stress in Pakistan. Published in the journal ‘Cleaner Water’ (translated as ‘更清洁的水’), the research offers a nuanced understanding of how economic openness, institutional quality, and sectoral dynamics influence water stress, with significant implications for policy makers and industries alike.
The study, which analyzed data from 1999 to 2023, employed a sophisticated Autoregressive Distributed Lagged (ADL) model and other advanced econometric techniques to dissect the drivers of water stress. The findings reveal a intricate web of influences, with agricultural output and population density emerging as significant contributors to increased water stress. “We found that agricultural output has a substantial positive effect on water stress levels,” Munir explains. “This is a critical insight, given that agriculture accounts for a significant portion of Pakistan’s water usage.”
Surprisingly, the stringency of environmental policy was also found to have an unexpectedly positive effect on water stress levels. This counterintuitive result suggests that the implementation and enforcement of environmental policies may be lacking, leading to adverse outcomes. “Our findings highlight the importance of not just having strong environmental policies, but also ensuring their effective implementation,” Munir notes. “This is a key area where policy makers can make a significant impact.”
The study also examined the role of foreign direct investment (FDI) and trade openness in influencing water stress. While FDI was found to have a lagged positive effect on water stress, trade openness did not significantly influence water stress levels. This suggests that the benefits of trade openness in mitigating water stress may be outweighed by other factors, such as agricultural demands and urban agglomeration.
For the energy sector, these findings are particularly relevant. Water is a critical input for many energy production processes, and water stress can lead to increased costs and operational challenges. Moreover, the energy sector is not immune to the impacts of environmental policies and their enforcement. As such, the study’s insights can help energy companies better understand and navigate the water stress landscape in Pakistan.
Looking ahead, the research underscores the need for policy reforms in irrigation efficiency, infrastructure, and urban planning. It also highlights the importance of improving the enforcement of environmental policies to achieve desirable outcomes. “Our study provides a roadmap for policy makers to leverage governance and practices in water use,” Munir says. “By addressing these issues, we can make significant strides towards achieving the Sustainable Development Goal 6, which aims to ensure availability and sustainable management of water and sanitation for all.”
In the broader context, this research represents a significant advancement in empirically evaluating dynamic relationships in water stress. It also contributes to Institutional Theory by reinforcing how policy implementation deficiencies can lead to adverse outcomes. As such, it offers valuable insights for policy makers, industries, and researchers alike.
However, the study is not without its limitations. The use of provincial data bases restricts the usefulness of the findings beyond the provincial level. Future studies could explore sub-national modes of policy variations to provide more granular insights. “Without this level of detail, national level policy strategies may be misaligned due to imprecise interpretation of local micro-based regional water stress coordinating dynamics,” Munir cautions.
In conclusion, this research offers a compelling narrative of the complex dynamics driving water stress in Pakistan. By shedding light on the role of economic openness, institutional quality, and sectoral dynamics, it provides a valuable resource for policy makers and industries seeking to navigate this critical issue. As the world grapples with the challenges of water scarcity, studies like this one offer hope for a more sustainable and water-secure future.
