Bangladesh – Cyclone Mora has battered Bangladesh, killing at least three people and wreaking havoc in camps housing Rohingya refugees. The tropical storm has forced almost 500,000 people to flee coastal villages. Packing heavy rain and winds, the storm made landfall between Cox’s Bazar and the port city of Chittagong early on Tuesday morning.

Brazil – Heavy rains and flooding have driven tens of thousands of Brazilians from their homes in the country’s northeast and caused at least six deaths, authorities said Monday. The state of Pernambuco has declared a state of emergency in 14 cities affected by heavy rains in recent days. More than 40,000 people have fled their homes, some of which have been destroyed, as flood waters rose waist-high in some places. Two people have died, state officials said. In the neighboring state of Alagoas, more than 2,000 families have been forced from their homes and four people have died, authorities said.

Great Barrier Reef can no longer be saved

The Great Barrier Reef can no longer be saved in its present form partly because of the “extraordinary rapidity” of climate change, experts have conceded.

Like coral across the world, the reef has been severely damaged by the warming of the oceans with up to 95 per cent of areas surveyed in 2016 found to have been bleached.

Bleaching is not always fatal but a study last year found the “largest die-off of corals ever recorded” with about 67 per cent of shallow water coral found dead in a survey of a 700km stretch.

Now experts on a committee set up by the Australian government to improve the health of the reef have revealed that they believe the lesser target of maintaining its “ecological function” is more realistic.

The concept of ‘maintaining ecological function’ refers to the balance of ecological processes necessary for the reef ecosystem as a whole to persist, but perhaps in a different form, noting the composition and structure may differ from what is currently seen today.

Disease

Guinea worm disease

There were 3.5 million Guinea worm disease cases in 21 countries in Africa and Asia in 1986. According to the Carter Center, 25 human cases of Guinea worm disease in three countries were reported in 2016.

The first three months of 2017, only three cases have been reported, all from Chad.

However, according to a World Health Organization (WHO) Weekly Outbreak Bulletin today, it is reported that there were 21 suspected cases of Guinea worm reported from Tonj East County, in Warrap State in northwest South Sudan.
