A/RES/65/1 to address those vulnerabilities through the full and effective implementation of the Mauritius Strategy for the Further Implementation of the Programme of Action for the Sustainable Development of Small Island Developing States. 11 We also recognize that the adverse effects of climate change and sea-level rise present significant risks to the sustainable development of small island developing States. We note the uneven progress of small island developing States in achieving the Millennium Development Goals and express concern that progress in some areas has been lagging. In this regard, we welcome the five-year high-level review of the Mauritius Strategy to be conducted on 24 and 25 September 2010 to assess progress made in addressing the vulnerabilities of small island developing States. 10F 33. We recognize that more attention should be given to Africa, especially those countries most off track to achieve the Millennium Development Goals by 2015. Progress has been made in some African countries, but the situation in others remains a grave concern, not least because the continent is among the hardest hit by the financial and economic crisis. We note that aid to Africa has increased in recent years; however, it still lags behind the commitments that have been made. We therefore strongly call for the delivery of those commitments. 34. We recognize also the specific development challenges of middle-income countries. These countries face unique challenges in their efforts to achieve their national development goals, including the Millennium Development Goals. We also reiterate that their efforts in that regard should be based on national development plans that integrate the Millennium Development Goals and should be adequately supported by the international community, through various forms, taking into account the needs and the capacity to mobilize domestic resources of these countries. 35. We acknowledge that disaster risk reduction and increasing resilience to all types of natural hazards, including geological and hydro-meteorological hazards, in developing countries, in line with the Hyogo Framework for Action 2005-2015: Building the Resilience of Nations and Communities to Disasters, 12 can have multiplier effects and accelerate achievement of the Millennium Development Goals. Reducing vulnerabilities to these hazards is therefore a high priority for developing countries. We recognize that small island developing States continue to grapple with natural disasters, some of increased intensity, including as a result of the effects of climate change, impeding progress towards sustainable development. 1F The way forward: an action agenda for achieving the Millennium Development Goals by 2015 36. We resolve to promote and strengthen national ownership and leadership of development as a key determinant of progress in achieving the Millennium Development Goals, with each country taking the primary responsibility for its own development. We encourage all countries to continue to design, implement and monitor development strategies tailored to their specific situations, including through broad consultations and participation of all relevant stakeholders, as appropriate for each national context. We call on the United Nations system and _______________ 11 Report of the International Meeting to Review the Implementation of the Programme of Action for the Sustainable Development of Small Island Developing States, Port Louis, Mauritius, 10–14 January 2005 (United Nations publication, Sales No. E.05.II.A.4 and corrigendum), chap.
