Sustainable Development

Blockchain is mainstreaming, but the number of blockchain for development use-cases with proven success beyond the pilot stage remain relatively few. This paper outlines key blockchain concepts and implications in order to help policymakers reach realistic conclusions when considering its use. The paper surveys the broad landscape of blockchain for development to identify where the technology can optimise development impact and minimise harm. It subsequently critically examines four successful applications, including the World Food Programme’s Building Blocks, Oxfam’s UnBlocked Cash project, KfW’s TruBudget and Seso Global. As part of the on-going work co-ordinated by the OECD’s Blockchain Policy Centre, this paper asserts that post-COVID-19, Development Assistance Committee (DAC) donors and their development partners have a unique opportunity to shape blockchain’s implementation.

In 2018, the city of Cape Town, South Africa, was close to the 'Day Zero', requiring all taps to be shut off and citizens to fetch a daily 25 litre per person. Though the day-zero was avoided, it is estimated that, at the current rate, South Africa will experience a 17% water deficit by 2030 if no action is taken to respond to existing trends. Lessons learned during that drought crisis have been valuable for the city to manage the short-term COVID-19 implications and design long-term solutions towards greater water resilience. As a result of a multi-stakeholder policy dialogue involving 100+ stakeholders from the city of Cape Town and South Africa, this report assesses key water risks and governance challenges in Cape Town, and provides policy recommendations towards more effective, efficient and inclusive water management building on the OECD Principles on Water Governance. In particular, the report calls for strengthening integrated basin governance, transparency, integrity, stakeholder engagement, capacities at all levels of government, financial sustainability and for advancing the water allocation reform to better manage trade-offs across multiple users.

This report is the first OECD review of South Africa’s environmental performance. It has been carried out as part of the OECD dialogue with South Africa as Key Partner. The report evaluates South Africa's progress towards sustainable development and green growth, with a focus on policies that provide incentives to protect South Africa's exceptionally rich biodiversity and promote more effective and efficient environmental management across different levels of public administration.
