Four years ago, the world adopted an ambitious set of Sustainable Development Goals (SDGs) designed ‘to end poverty, protect the planet and ensure that all people enjoy peace and prosperity by 2030’. Despite rising life expectancy and the eradication of many endemic diseases, more than 400 million people in the member states of the Islamic Development Bank (IsDB) still live in absolute poverty, subsisting on less than US$1.90 per day. It is, perhaps, these countries that face the greatest challenges in fulfilling the SDGs. Traditional methods of development finance have struggled to alleviate the extreme poverty in some regions of the world, leaving the poorest populations without the basic building blocks needed to lead healthy lives and build dignified livelihoods. Many remain deprived of primary healthcare, protection against infectious diseases, a sufficient and nutritious food supply, potable water, clean power, and sanitation.
