Garbage is an endemic problem in developing cities due to the continual inux of migrants from rural areas coupled with deficient municipal capacity planning. In cities like Dhaka, open waste dumps contribute to the prevalence of disease, environmental contamination, catastrophic ooding, and deadly fires. Recent interest in the garbage problem has prompted cursory proposals to introduce technology solutions for mapping and fundraising. Yet, the role of technology and its potential benefits are unexplored in this large-scale problem. In this paper, we contribute to the understanding of the waste ecology in Dhaka and how the various actors acquire, perform, negotiate, and coordinate their roles. Within this context, we explore design opportunities for using computing technologies to support collaboration between waste pickers and residents of these communities. We find opportunities in the presence of technology and the absence of mechanisms to facilitate coordination of community funding and crowd work.
