Appropriate and sustainable rural technologies are very rare as most of the global attention, driven by economical interests, is focused on urbanization. Such technologies are very poorly needed because of several reasons. They are, also, imperative for promoting successful long-term and large-scale sustainable urbanization. This is, even, essential in agricultural regions where rural communities are major parts of the national socio-economic structure, which is the case in many developing countries in particular Africa. This is at least necessary in the transition periods prior to large-scale and long-term transformation to urbanized societies where gradual, appropriate and sustainable integration of rural regions is necessary.
Urbanization has caused an accelerating drain of un-favored groups to mega and large cities (http://www.academia.edu/847075/Mexico_City._The_marginal_communities_social_and_ethnic_segregation_of_the_native_population). The random and rapid expansion of urbanized regions has promoted an ever accelerating pile-up of slum-communities in many regions around the world (http://www.schooljotter.com/showpage.php?id=158173) which indeed is not sustainable both from the economic and environmental perspective.
Some parts of the problem are associated with the negative impacts from global education, research and technology driven-policies around the world by being supported by national and international institutes and organizations including the United Nations and World Bank. Management of research, education and development programs fails to involve people from the developing countries to contribute in solving problems and difficulties in their native countries or at least to find partners from the developed countries willing to participate in solving the enormous problems and difficulties in this respect.
Fortunately, the global community started to recognize such problems and to take steps and efforts, though limited in extent, for achieving successful socio-economic development that is very much related to reducing poverty and the associated impacts of environment and climatic threats. An innovative example “Ecological System Designs for the Indigenous Community of Maruata, Michoacan, Mexico” is given here where researchers from the developing countries are demonstrating how to bring about successful ecological designs for living better, cheaper and ecologically sustainable.
