About 3ieThe International Initiative for Impact Evaluation (3ie) is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding, producing and synthesising high-quality evidence of what works, for whom, why and at what cost. We believe that high-quality, policy-relevant evidence will help make development more effective and improve people's lives. 3ie in-house systematic reviews 3ie in-house systematic reviews appraise and synthesise the available high-quality evidence on the effectiveness of social and economic development interventions in low-and middle-income countries. 3ie's specialists follow scientifically recognised methods in conducting these reviews. They are quality assured according to internationally accepted standards. They are peer reviewed by members of an expert advisory group and three anonymous external reviewers. 3ie is providing leadership in demonstrating rigorous and innovative review methodologies, such as using theory-based approaches suited to informing policy and programming in the dynamic and challenging contexts of low-and middle-income countries.About this systematic review summary report 3ie systematic review summary reports distil key analyses and present the findings and recommendations of a full systematic review for policymakers and programme managers. The impact of education programmes on learning and school participation in low-and middle-income countries is based on a full review, Interventions for improving learning outcomes and access to education in low-and middle-income countries: a systematic review, which is available on the 3ie website. The summary report was peer-reviewed internally and by members of the expert advisory group convened for the full review.

Information technology plays an important role in facilitating disaster management and allowing planners for a more efficient disaster handling. Climate change can reasonably be expected to increase countries' vulnerability to natural hazards in future. We are already witnesses of extreme meteorological phenomena, such as expanded fires and floods. This paper gives Mobile Ad-Hoc Network (MANET) along with Dynamic Source Routing protocol (DSR). Simulation results for performance measurement of DSR algorithm for normal condition are given first. Same parameters are measured after applying disaster condition on nodes is presented in next section. In last section simulation results of disaster prevention condition are given. It is observed that performance of the network after application of prevention condition is nearly same as the normal performance. The performance is evaluated in terms of Network Throughput, Packet Delivery Ratio, and Average end to end delay Keywords-MANET, DSR Algorithm, throughout, PDR, end to end delay
