UN member states have committed to a decade of action to deliver the Sustainable Development Goals （SDGs） by 2030. There is no time for delay.
According to UN estimates in the World Economic Situation and Prospects 2020 report， the global economy sank to a recent low in 2019. World GDP growth slipped to 2.3 percent， while world trade growth slowed to 0.3 percent， the worst performance in the last 10 years.
Mounting challenges
The global economy continues to face a host of risks and uncertainties， including continued trade tensions， escalating geopolitical confl icts， elevated debt levels， as well as catastrophic climate shocks. Provided these factors can be contained， a modest uptick in global growth to 2.5 percent is projected for 2020. However， the risks of a further deterioration in the economic situation remain high. Prolonged weakness in global economic activity may cause signifi cant setbacks for sustainable development， including the goals to eradicate poverty and create decent jobs for all.
The share of the world population living in extreme poverty has declined steadily and signifi cantly over the past few decades， largely due to successful experiences in China and India. Although progress has been made in global terms， in the last few years the number of people living in extreme poverty has been rising in several sub-Saharan countries and in parts of Latin America and West Asia. At the same time， pervasive inequalities and the deepening climate crisis have fueled growing discontent in many parts of the world.
Economic growth around the world remains very uneven. Despite significant headwinds from global trade tensions， East Asia remains the worlds fastest growing region and the largest contributor to worldwide growth， but globally， one in f ive countries will see per-capita income stagnate or decline in 2020. Many of these are commodity exporters， which are still ailing from the effects of the commodity price downturn of 2014-16. In one third of commodity-dependent developing countries—home to 870 million people—average real incomes are lower today than they were in 2014. This includes several larger economies， such as Angola， Argentina， Brazil， Nigeria， South Africa and Saudi Arabia. In addition， Africa has experienced a decade of near stagnation in percapita GDP， notwithstanding some bright spots such as Ethiopia， Rwanda and Cote dIvoire. Meanwhile， average per-capita incomes in Latin America and the Caribbean are about 4 percent lower today than in 2014.
With the deteriorating economic outlook， central banks around the world have once again become the main line of defense. A total of 64 central banks reduced interest rates in 2019， marking the broadest shift in monetary policy since the 2008 global fi nancial crisis. However， it has become clear that overreliance on monetary policy is not just insufficient to revive economic growth， but also entails signifi cant costs， including an increase in fi nancial stability risks in the future.
Meanwhile， investors continue to under- estimate climate risks， encouraging shortsighted decisions that expand investment in carbon-intensive assets. This leaves many governments and investors exposed to sudden losses， while posing substantial setbacks to sustainable environmental targets. The only way to decisively sever the link between greenhouse gas emissions and economic activity is to change the energy mix and move away from burning fossil fuels. Energy transition is expected to have substantial social consequences， which will fall unevenly within and among countries. Measures to compensate those who are disproportionately impacted are essential to protect vulnerable populations and safeguard the political viability of diffi cult but urgently needed policy actions.
Policy options
As we enter this decade of action， it is time for a reset in economic policy-thinking. A more balanced policy mix is called for to stimulate healthy economic growth while moving toward greater social inclusion， gender equality and environmentally sustainable production. More effective and accountable mechanisms are needed to shift the focus of policymaking from short-term targets toward longer-term planning for inclusive economic development.
Countries should make use of available fi scal space to advance development goals. Even where fiscal space is tight， there is ample scope to improve the efficiency and design of fiscal， industrial and labor market policies so that they are well-coordinated and optimized to deliver the SDGs.
Policy uncertainty is the number one factor holding back much-needed investment from reaching development targets. To ease these uncertainties， more efforts are needed for multilateral solutions to trade issues. It is also imperative to clarify and commit to policies that will combat climate change and deliver energy transition， and to develop transparent international finance arrangements and effective debt resolution mechanisms.
The biggest challenges of this age cannot be addressed by national policies alone. Strong global leadership and a commitment to change will be crucial in reaching our common aims of achieving sustainable economic growth and improving the wellbeing of all of humanity.
