challenges. From the absence of data to trade tensions and COVID-19, these challenges represent a threat for the progress made. Links with other SDGs The success of the 2030 agenda requires inclusive partnerships to achieve the common goals adopted. These partnerships need to be set at the different constituencies (local, national, regional and global level) and consider the Sustainable Development Goals'principles, vision and values to place people and planet first now more than ever to recover from crisis and build back while achieving the SDGs. More often than not, the actualization of the SDGs, at the global level, depends on the effectiveness of the official development assistance. The Official development assistance needs to leverage on international collaboration for the public financing of the developing countries that remained unfulfilled by the donors. It is the responsibility of the official development assistance to ensure that, most developing countries are supported in areas of water and sanitation related activities and programs rather than making use of their domestic resources, tariffs and public finance obtain through taxation. Challenges Impacts and responses to Covid-19 pandemic The UN Secretary-General gave a development of strategy that spread out a dream for how the global network can show a powerful, organized reaction to the COVID-19 pandemic. The 2020 Financing for Economical Advancement Report traces measures to address the effect of the unpacked worldwide back down and financial crisis, particularly within the world's poorest nations. To support the poor communities they also started a UN Reaction and Trust Fund. Unfortunately, remittances to low income countries are expected to fall and global investment is expected to decline by 40% owing to the pandemic. World Health Organization (WHO), in collaboration with the UN Establishment advanced a first-of-its-kind Solidarity Reaction Support to permit enterprises and people to contribute to WHO's COVID-19 reaction. Partnerships with private finance There are concerns that Target 17.17 could undermine the rest of the SDGs. Indeed, according to a 2018 UN Report, "in terms of costs, private finance is more expensive than public finance, and public-private partnerships can also incur high design, management and transactional costs due to their complexity and the need for external advice". In addition, negotiations of these public-private partnerships can cause project delays of some years.
