Facing water shortages and escalating fertilizer costs, farmers in developing countries are using raw sewage(下水道污水)to irrigate and fertilize nearly 49 million acres of cropland, according to a new report-and it may not be a bed thing.
While the practice carries serious health risks for many, those dangers are outweighed by the social and economic gains for poor urban farmers and consumers who need affordable food.
"There is a large potential for wastewater agriculture to both help and hurt great numbers of urban consumers," said Liqa Raschid-Sally, who led the study.
The report focused on poor urban areas, where farms in or near cities supply relatively inexpensive food. Most of these operations draw irrigation water from local rivers or lakes. Unlike developed cities, however, these areas lack advanced water-treatment facilities, and rivers effectively become sewers.(下水道)
When this water is used for agricultural irrigation, farmers risk absorbing disease-causing XX, as do consumers who eat the produce raw and unwashed. Nearly 2.2 million people die a year because of diarrhea-related(与腹泻相关的)diseases, according to WHO statistics. XXX than 80% of those cases can be attributed to contant with contaminated water and a lack of XXX anitation. But Pay Drechsel, an environmental scientist, argues that the social and economic benefits of using untreated human waste to grow food outweigh the health risks.
Those dangers can be addressed with farmer and consumer education, he said, while the free water and nutrients from human waste can help urban farmers in developing countries to escape poverty.
Agriculture is a water-intensive business, accounting for nearly 70% of global fresh water consumption.
In poor, dry regions, untreated wastewater is the only viable irrigation source to keep farmers in business. In some cases, water is so scarce that farmers break open sewage pipes transporting waste to local rivers.
Irrigation is the primary agricultural use of human waste in the developing world. But frequently untreated human waste is used on grain crops, which are eventually cooked, minimizing the risk of transmitting water-borne diseases. With fertilizer prices jumping nearly 50% per metric ton over the last year in some places, human waste is an attractive, and often necessary, alternative.
In cases where sewage mud is used, expensive chemical fertilizer us can be avoided. The mud contains the same critical nutrients.
"Overly strict standards often fail," James Bartram, a WHO water-health expert, said. "We need to accept that fact across much of the planet, so waste with little or no treatment will be used in agriculture for good reason."

D.He deems it indispensable for combating global poverty.
Turning once again to the question of invasion, I would observe that there has never been a period in all these long centuries of which we boast when an absolute guarantee against invasion, still less against serious raids, could have been given to our people. In the days of Napoleon the same wind which would have carried his transports across the Channel might have driven away the blockading (封锁) fleet. There was always the chance, and it is that chance which has excited and befooled (愚弄) the imaginations of many continental tyrants. Many are the tales that are told. We are assured that novel methods will be adopted, and when we see the originality of malice (怨恨), the ingenuity of aggression, which our enemy displays, we may certainly prepare ourselves for every kind of novel stratagem (战略) and every kind of brutal and treacherous (奸诈)maneuver (花招). I think that no idea is so outlandish (古怪的) that it should not be considered and viewed with a searching, but at the same time, I hope, with a steady eye.
We must never forget the solid assurances of sea power and those which belong to air power if it can be locally exercised. I have, myself, full confidence that if all do their duty, if nothing is neglected, and if the best arrangements are made, as they are being made, we shall prove ourselves once again able to defend our island home, to ride out the storm of war, and to outlive the menace (威胁) of tyranny, if necessary for years, if necessary alone. At any rate, that is what we are going to try to do. This is the resolve of His Majesty's government - every man of them. This is the will of parliament and the nation. The British Empire and the French republic, linked together in their cause and in their need, will defend to the death their native soil, aiding each other like good comrades to the utmost of their strength. Even though large tracts of Europe and many old and famous states have fallen or may fall into the grip of the Gestapo and all the odious (可憎的) apparatus of Nazi rule, we shall not flag (变弱) or fail.
We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost might be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills, we shall never surrender, and even if, which I do not for a moment believe, this island or a large part of it were subjugated (征服) and starving, then our empire beyond the seas, armed and guarded by the British fleet, would carry on the struggle, until, in God's good time, the new world, with its power and might, steps forth to the rescue and the liberation of the old.
