This book asks serious questions about how to improve the process of effective urban poverty action, with particular emphasis on how to bridge the gap between those taking action and those making policy decisions. However, the observations, lessons-learned and guidelines identified are also of great use to practitioners and policy makers in all poverty alleviation work. As increased developmental analysis and research has been directed at improving delivery of urban poverty alleviation one important problem has been identified: the serious communication gap between those at the top who formulate policy and those at mezo- and micro-levels who implement policy. As a result development institutions are more conscious of the need to improve micro-level practitioners' capacity to influence policy level decision making and budgeting. The first part of the book addresses the wider issues of networking and partnerships as a mean to influence policy by evidence derived from action. It examines the institutionalized mechanisms built into these new partnerships between northern and southern development institutions to ensure that the northern institutions have clear and comprehensive information about the realities on the ground from their southern partners, and explores some of the implications of these mechanisms for the future. The second part consists of eight country-based case studies which discuss how practitioners in both southern and northern NGOs have faced the problem of communication between workers at different levels of a development institution, and how the lessons learned from implementation can be transmitted to middle level service providers, and from them to policy makers. In conclusion the authors draw guidelines from the case studies, giving pointers on how to capitalize on past successful linkages and to deal successfully with constraints and gaps.
