发展中国家的公路当局认识到，必须使用基于当地资源的办法来维护农村地区的未铺设道路，而不是试图达到国际标准。作者开发了一种新的道路维护技术，我们称之为“Do-Nou”。自2006年以来，我们已经在亚洲、太平洋、非洲和拉丁美洲展示了这项技术。DO-NOU可以被归类为一种土工织物，只使用在发展中国家广泛可用的塑料农作物袋和当地非熟练工人来增强土壤的抗剪强度。经过一些修改后，这项技术也被应用于粘性地基上未铺设道路的维护，以及在洪水易发地区修建路堤挡土墙。事实证明，社区在农村地区采用DO-NOU技术维护未铺设的道路是可行的，从而增强了社区的复原力。肯尼亚政府在其道路战略计划中承认了Do-Nou技术，并投资培训其青年学习这项技术，以促进就业。
Road authorities in developing countries recognize the need to maintain unpaved roads in rural areas using local resource based approaches rather than by attempting to meet international standards. The authors have developed a novel road maintenance technique, that we call “Do-nou”. Since 2006, we have demonstrated this technique in Asia, the Pacific, Africa and Latin America. Do-nou can be classified as a geotextile used to reinforce the shear strength of soil using only plastic crop bags, which are widely available in developing countries, and unskilled local labor. After some modification, the technique was also applied to the maintenance of unpaved roads on the clayey ground and to the construction of retaining walls for road embankment in flood-prone areas. It was demonstrated that it was practical for the communities to maintain unpaved roads in rural areas when equipped with the Do-nou technique, thereby enhancing community resilience. The Kenyan Government has recognized the Do-nou technique in its road strategy plan and has invested in training its youth on this technique for employment promotion.
