Depressing reports about how quickly the world’s tropical forests are being felled are commonplace. But depressing reports about the state of the trees that are still standing are much rarer. In fact, a new study from the International Tropical Timber Organisation(ITTO), an offshoot of the United Nations, claims to be the first exhaustive survey of tropical-forest management ever undertaken. Its findings, although grim, do contain a kernel of hope.
The ITTO examined "permanent forest estate" , meaning land that the governments of its 33 members have formally set aside for forests, and is therefore subject to some form of regulation or protection. The category includes both national parks and timber concessions, in both public and private hands. It covers 814m hectares, and accounts for roughly two-thirds of the world’s tropical forests.
The concept is important, explains Duncan Poore, one of the authors of the report, because it is not always possible, or desirable, to protect every last grove against encroaching farms or homes. Instead, governments should concentrate on maintaining the forests that are the most commercially and scientifically valuable. Yet the ITTO’s researchers found that only 15% of the permanent forest estate has a management plan, and less than 5% of it is sustainably managed. That still amounts to an area the size of Germany, the report notes, and represents a dramatic improvement since 1988, when an earlier and less extensive survey found that only one country in the tropics—Trinidad and Tobago—had any well-run forests at all. But relative to the area of forest that has disappeared over the same period, the well-managed area is negligible.
The crux is bad government. Poor countries do not always have good forestry laws. Even when they do, they rarely have the capacity to enforce them. It is no coincidence that Malaysia, the country with the highest proportion of prudently managed forest in the study, is also one of the richest. Countries with the worst run forests, meanwhile, are war-torn places such as Congo and Cambodia.
More surprising, perhaps, is the difference the report found between forests where logging is allowed, and those that have been earmarked for conservation. Some 7% of "production" forests, it turns out, are in good shape, compared with just 2.4% of "protection" forests. As Dr Poore points out, it is easy to undertake to preserve a forest, but difficult to do so in practice. Timber concessionaires at least have an incentive to look after their property, while ill-paid and ill-equipped forestry officials often have neither. Exploiting forests may prove the best way to preserve them.
It is hard to preserve a forest because
选项
A、forestry officials don’t consider it important.
B、forests are there to be cut and exploited.
C、it is not profitable for forestry officials.
D、governments don’t pay attention to it.
答案
C
解析
推断题。由题干中的preserve a forest定位至末段。该段倒数第二句解释了森林难以保护的原因,由此可以推断,这里是说保护林地对于林业官员而言无利可图,因此他们没有动力这样做,故[C]为答案。文中只提到了ill-paid and ill-equipped forestry officials,没有提及他们的认识,排除[A];[B]是针对末段末句设计的干扰项,但该句不是解释难以保护林地的原因,排除[B];末段没有提及政府问题,排除[D]。
