Having an integrated SP information system would allow policymakers to better monitor inputs, outputs and outcomes  . Based on evidence from the assessments of three countries , the political and institutional arrangements  is as important as the technical fixes  in the success of using information and communication technology for delivering SP programmes . By 2050, climate-induced migration will likely be a major policy aspect of the rural-urban nexus as slow-onset impacts of climate change in sub-Saharan Africa, South Asia and Latin America will likely force over 143 million people to migrate within their national borders . This will have major implications for SP systems, and therefore national SP strategies should be designed to anticipate and address climate-induced internal mobility . For instance, it does not offer a solution for maintaining Indigenous cultures which are often strongly affected by, or even disrupted by, climate change . Hence, an effective approach needs to combine different policy instruments to support protection, adaptation and migration .
