This literature review surveys three key academic sources to explore water sustainability and delivery challenges in the developing world, with a focus on informing research into Caribbean water systems. The review examines the role of remote sensing and GIS technology in groundwater management, the real-world implementation failures of Integrated Water Resources Management (IWRM) in South Africa, and a broader philosophical critique of IWRM's conceptual vagueness. Collectively, the sources demonstrate that effective water delivery is as much a political and organizational problem as a technical one, underscoring the need for political will, trained personnel, and practically grounded policy frameworks.
Water sustainability has been of increasing concern in academia as both a political and an environmental problem. This dissertation will specifically focus on water sustainability in the Caribbean and how to improve methods of delivery. Water is a finite, not an infinite, resource and must be treated as such. Additional research is needed to determine how best to improve current water quality and availability in the region. One useful method of doing so is reviewing how governments have tried — and in some cases failed — to improve water sustainability in other areas of the developing world.
Technology provides many potential benefits for improving water quality, according to Jha et al. (2007). In the article "Groundwater Management and Development by Integrated Remote Sensing and Geographic Information Systems: Prospects and Constraints," the authors examine how the pollution and exploitation of groundwater is creating a critical problem for the environment in India. Remote sensing (RS) and geographic information systems (GIS) can help circumvent some of these issues, although the technology is still in its nascent stages. The uses for RS and GIS include the assessment of current resources and damages; selecting artificial recharge sites; flow and pollution modeling; hazard assessment and protection; estimating natural recharge of groundwater; and other forms of data analysis and process monitoring (Jha 2007: 427). Groundwater is a critical natural resource because of its relatively low vulnerability even when the rest of a region faces drought, making its maintenance vital to future survival.
Unfortunately, several logistical barriers exist to the use of RS and GIS technology in nations where the need for it is deepest and most critical, such as India. A literature review reveals that current studies proving the utility of technology in improving groundwater in the region are limited and not scientifically rigorous. While the developed world is currently monitoring its groundwater using cutting-edge technology, developing-world governments often impose security restrictions that prevent the free dissemination of information, and there is a lack of funding for facilities. The authors conclude with recommendations for improvement, including offering more affordable technology, facilitating greater data-sharing about groundwater, and providing training on how to use the technology. Improvements in infrastructure are also identified as critical (Jha 2007: 461).
The Jha et al. (2007) article highlights how simply having high-quality technology is not enough — it must be used effectively. Moreover, government intransigence can result in failure of proper training and delivery, as can financial constraints. According to Jonker (2007), in his article "Integrated Water Resources Management: The Theory–Praxis–Nexus, a South African Perspective," the use of Integrated Water Resources Management (IWRM) in South Africa has been a struggle despite the fact that the program appeared well-designed and was widely praised when initially implemented. South Africa was lauded for being a leader in the use of IWRM in Africa, but implementation has met a number of logistical barriers, including insufficient numbers of trained personnel, inadequate funding, and a lack of genuine follow-through by political leaders (Jonker 2007: 1257).
There was also a lack of what Jonker calls "conceptual clarity" in the use of techniques by the South African government agencies charged with IWRM enforcement. Ideally, IWRM is supposed to promote the coordinated development and management of resources to improve economic and social welfare, but problems arose regarding the human element. The article highlights that no system, no matter how well-supported by prior evidence, can be more powerful than the human actors responsible for implementing it (Jonker 2007: 1262). A lack of integration among agencies resulted in an unsuccessful outcome because those in charge appeared to fail to understand the full scope of the program and where their specific functions fit within its larger aims. Coordinating resources among affected parties is challenging from an organizational perspective and can thwart even a well-structured program's implementation.
"Biswas critiques IWRM's conceptual vagueness globally"
All three of these articles highlight the need to view sustainable water delivery as a political problem. Although environmental issues must be studied to determine the best way to provide safe and reliable clean water to residents, without political will and logistical planning, technical solutions will mean little. Equally, a program cannot be excessively theoretical or conceptual in nature if it is to succeed in practice.
