In the past few editions I have been addressing the recognition of the global water crisis, its relationship to the effects of climate change, and its implications for the future provision of this most valuable commodity and for worldwide health and security. I have suggested water as an alternative to coal, oil, and gas as a standard around which we calculate value and organize our communities, economies, and international relationships. It may seem a drastic idea, but if you take some time to think it through, you may discover a compelling logic, a recalculation of value, a strategy for action, even a plan that might enable necessary change away from a destructive status quo toward a realizable future using existing technology and reallocated financial assets.
How would it work? Let me give you an example of a planning initiative that speaks to the why and how. The Nile River Basin comprises 3 million square kilometers along a 6,695 kilometer course starting at the head water in Rwanda and Burundi, supports millions of people in ten riparian nations along the watershed, and descending to Egypt and the Mediterranean Sea. The basin accounts for 10% of Africa's land mass, but includes 25% of its burgeoning population. The river's erratic flow, and the associated activities supported by that flow, has been severely impacted by climate change factors-temperature rise, persistent drought, extreme weather, flooding, and the inevitable socio-economic consequence in terms of energy and food production, health and sanitation, employment, poverty, and regional security.
To understand the gravity of the problem and to begin defining its solution, the UN Environment Programme (UNEP), in cooperation with the Nile Basis Initiative, with support by the Swedish International Development Agency, retained the Danish Hydraulic Institute (DHI), one of the world's largest and most accomplished hydraulic engineering and design organizations, to gather all available data regarding all activities and needs throughout the watershed, to generate from that data a complex hydraulic model through which to model climate change projected effects, growing demand, and multiple requirements for water resources throughout the entire basin over time.
The DHI, a non-profit consulting firm chartered by the Danish Government, has developed proprietary software capacity that can assimilate massive amounts of data, process and visualize it, and make it adaptable for testing impacts of projected future conditions and scenarios. It is an astonishing planning tool. The Nile model includes rainfall, runoff, lakes, reservoirs, dams, wetlands, and irrigation water demands. The projections applied cover two 30-year periods: from 2020 to 2049 and from 2079 to 2099. Comparing the changing capacity with population growth, rural and urban shifts, and agricultural and manufacturing needs revealed not just what amount of water might be available, but also how what is available can be efficiently and effectively managed. From this information, very specifically located in a place, a region, a settlement, or a nation, decision-makers were provided with informed conditions on which they could evaluate and place water dependent uses, target limited financial resources, and understand the management practices and professions for which to train personnel to operate the system in the future.
Please take a moment to think about the implications of this, not only for the Nile River, but also for all the other interstate and transnational watersheds around the world that could benefit from a similar understanding of the hydraulic reality on which their future viability will depend. For such a system to work requires local knowledge, communication, cooperation, consensus agreement, implementation, evaluation, and further planning and action, all bringing together managers from nations sometimes antagonistic over other issues, but understanding that without such agreement and collaborative action, the absence of adequate water supply at any point along the line will lead to deprivation, dissatisfaction, and unrest.
Apply this methodology to any waterway you know and you immediately see how decisions made upstream or down, indifferent to conditions downstream or up, are the instigators of competition and conflict that most often does not serve anyone well.
The Nile Basin Initiative is just one amazing example of planning with water. Take your thinking one step further: if nations can find consensus and compromise around water as an egalitarian human right, what else might they find possible through this first success? What other agreement might be found through the understanding and experience derived from one system that unites us all?
