"Rio Summit: Little Progress, 20 Years On"
"On the final day of the UN sustainable development summit in Rio, UN chief Ban Ki-moon has urged governments to eliminate hunger from the world."
"The secretary-general said in a world of plenty, no-one should go hungry.
The final phase of the summit has seen pledges from countries and companies on issues such as clean energy.
But a number of veteran politicians have joined environment groups in saying the summit declaration was 'a failure of leadership'.
And UK Deputy Prime Minister Nick Clegg described the outcome as 'insipid'."
