The world must assess what progress has been made in creating a sustainable future, President Jacob Zuma said in Brazil on Thursday.

"Have the financial, technical and capacity constraints of developing countries been enhanced to such an extent that they can achieve poverty eradication and sustainable development?" Zuma said in a speech prepared for delivery at the Rio+20 United Nations Conference on Sustainable Development.

Zuma said for decisions made at the event to be effectively implemented, it was crucial that the required financial systems were available.

"These would be aimed at ensuring sustained finance for sustainable development and poverty reduction, environmental sustainability and social cohesion."

New financial resources would help developing countries pursue outcomes arising from the conference.

"By the same token we recognise the need for countries to explore more innovative finance mechanisms to upscale implementation in this regard."

Zuma cited the creation of the Green Fund and the role public-private partnerships played in implementing sustainable development programs within South Africa.

Public-private partnerships would also help nurture small and medium-sized enterprises to boost the green economy, green policies, job creation, and reduce poverty levels.

However, while much had been achieved, more needed to be done, Zuma said.

"Our key objective is to ensure that sustainable development imperatives remain central in our planning and execution at local, national and global levels."
