At the end of the 13 yr war in Afghanistan and over $100 billion in development efforts, Afghanistan is beginning anew with her first peaceful and democratic transfer of political power. This transition, unfortunately, is occurring in the most fragile state outside of sub-Saharan Africa and during diminishing stability and development gains due to Islamic jihadist rebel actions in Iraq. In order for Afghanistan’s transition to the world stage to maintain a positive trajectory and be lasting, aid needs to be reformed to better meet the long-term needs of the Afghan people. Keen planning by the U.S. Army provided such an outlet for military-development assistance, the Agriculture Development Teams (2008–2014). These special teams supported Afghanistan’s primary driver of survival, employment, and productivity: water/agriculture. Using only 0.04% of U.S. development funding, these teams provided an improved approach to development by using widespread, community-accepted, sustainable projects, which included educational and training components using an “Afghan first” focus on contracting, materials, and labor. Water projects developed and implemented with the Afghan people focused on infrastructure and educational needs, providing a step forward in the progression of Afghanistan from subsistence to economic agriculture. Although these professional, egalitarian military teams are now inoperative, their efforts are being analyzed and included into new warfare expectancies. U.S. military might has become holistic and is leveraging all expertise to make future endeavors successful for the affected state. Using this improved approach to military aid, future operations should provide better, more meaningful support, increasing the likelihood of development success.

Efforts to improve water quality and quantity, and sanitation in the world are impeded by a variety of technical and socioeconomic issues often unfamiliar to well-motivated individuals. Sustainable technological improvement can be thwarted by the lack of consideration of regional norms, customs, mores, and traditions, and by the absence of feasibility assessment and coordination with the community both before and during instatement of local improvements. Specifically, the absence of coordination means not fully allowing users to define their needs, resources, issues, and maintainable solutions, and not understanding local and regional power dynamics and the ability of the community to provide long-term project stewardship. Other mistakes can include: a lack of long-term planning; inadequate scientific and engineering design and construction; lack of anticipation of contingencies and complicating issues and lack of adaptive management to deal with these unforeseen events; use of inappropriate technology; absence of educational efforts (both for the community to understand and provide stewardship for the project, and for the education of those installing the facilities in the community); lack of follow-up; and lack of technical expertise and leadership. There is no single approach to water and sanitation development that fits all situations. However, avoiding common pitfalls can bring these important resources to villages worldwide, and in the process empower communities, reduce sickness and mortality, and improve the human condition.

Earth systems, when understood and respected, have the intrinsic capability to be instrumental for sustainable international development. If applied wisely without sophisticated technology, natural processes themselves can serve to sustain and prosper life in specific situations. Global initiatives to provide safe surface and groundwater are booming, but a parallel emphasis on sustainable sanitation is lagging, leaving 2.5 billion people without access to improved sanitation. Many technically sophisticated sanitation systems exist but are beyond the means of those same billions. The Water and Sewage Transformation Endeavor (W.A.S.T.E.) is a program at Wheaton College (Wheaton, Illinois) bringing together undergraduate students and faculty from various natural and social sciences to address the global need for improved sanitation. The goal of the program is to develop a low-tech wastewater treatment system for the Global South and beyond. A laboratory-scale waste stabilization pond system was constructed and studied to compare its effectiveness at reducing biological oxygen demand (BOD), as an indicator of pathogen disinfection, by varying light intensity, temperature, and detention time. The system with the highest light intensity and temperature and longest detention time performed the best, achieving 95% total BOD reduction. The project time line includes phase 1 indoor experimentation, phase 2 installation and operation of an outdoor pilot system, and the final phase 3 development of training programs for deployment of the technology into areas of need. The overall program has already proven to be an excellent educational opportunity for undergraduate students. It will ideally benefit many other student practitioners, and local trainees at candidate sites.
