An Egyptian government program to pay traders to buy rice straw from farmers at the end of harvest has helped to combat one of Cairo’s ugliest features — a huge black cloud that hangs over the Egypt capital during the burning season.
Cairo is the world’s second most polluted megacity, the World Health Organization says, and the government is pursuing several initiatives to cut back greenhouse gas emissions.
One of the biggest contributors to the thick layer of smog has been the annual burning of rice straw by farmers who have no other means to dispose of it.
To tackle the problem, the government offered an incentive to traders to buy the straw from farmers amounting to 50 Egyptian pounds ($3) per ton, said Mohamed Salah, head of the Egyptian Environmental Affairs Agency (EEAA). They can then sell it as animal feed or for other uses.
The program appears to be bearing results.
“Today, the dark cloud season is over and all citizens in Egypt are saying that they have not sensed any significant problem relating to this, unlike what had happened in previous years,” Salah said.
An industrial boom in Egypt has also contributed to pollution, Salah said.’
“We have some small industries that are deregulated and are not in line with environmental standards. We have worked hard on these,” he said.
Reductions in Air Pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, a new study suggests.
The study, published in the journal Annals of the American Thoracic Society, reviewed interventions that have reduced air pollution at its source. It looked for outcomes and time to achieve those outcomes in several settings, finding that the improvements in health were striking.
Starting at week one of a ban on smoking in Ireland, for example, there was a 13 per cent drop in all-cause mortality, a 26 per cent reduction in ischemic heart disease, a 32 per cent reduction in stroke, and a 38 per cent reduction in chronic obstructive pulmonary disease (COPD). Interestingly, the greatest benefits in that case occurred among non-smokers.
“We knew there were benefits from pollution control, but the magnitude and relatively short time duration to accomplish them were impressive,” said lead author Dean Schraufnagel from the American Thoracic Society in the US.
“Our findings indicate almost immediate and substantial effects on health outcomes followed reduced exposure to air pollution. It’s critical that governments adopt and enforce WHO guidelines for air pollution immediately,” Schraufnagel added.
According to the researchers, In the US a 13-month closure of a steel mill in Utah resulted in reducing hospitalisations for pneumonia, pleurisy, bronchitis and asthma by half.
School absenteeism decreased by 40 per cent, and daily mortality fell by 16 per cent for every 100 µg/m3 PM10 (a pollutant) decrease.
Women who were pregnant during the mill closing were less likely to have premature births.
A 17-day ‘transportation strategy,’ in Atlanta, Georgia during the 1996 Olympic Games involved closing parts of the city to help athletes make it to their events on time, but also greatly decreased air pollution.
In the following four weeks, children’s visits for asthma to clinics dropped by more than 40 per cent and trips to emergency departments by 11 per cent. Hospitalizations for asthma decreased by 19 per cent.
Similarly, when China imposed factory and travel restrictions for the Beijing Olympics, lung function improved within two months, with fewer asthma-related physician visits and less cardiovascular mortality.
“Fortunately, reducing air pollution can result in prompt and substantial health gains. Sweeping policies affecting a whole country can reduce all-cause mortality within weeks,” Schraufnagel said.
