How many regions are involved in the international study? [br]
Does organic farming foster biodiversity? The answer is yes, however, the number of habitats on the land plays an important role alongside the type and intensity of farming practices. These are the findings of an international study that looked at ten regions in Europe and two in Africa. The results has been published in Nature Communications. The study shows that even organic farms have to actively support biodiversity by, for example, conserving different habitats on their holdings.
An international team, including scientists from TUM, investigated the contribution of organic farming to supporting farmland biodiversity in the last two years. Researchers wanted to explore whether organic farms are home to more species than their conventional neighbors. The team used uniform methods across Europe to capture data and analyze it to establish the impact of farming methods and intensity and of landscape features on biodiversity.
"Organic farming is beneficial to the richness of plant and bee species. However, observed benefits concentrate on arable fields," says a TUM’s professor. His Chair for Organic Agriculture and Agronomy analyzed 16 Bavarian dairy farms.
The study investigated farms in twelve regions with different production systems. In each region, farms were selected randomly, half of them certified organic for at least five years. In Switzerland, grassland-based cattle farms were studied and in Austria the study looked at arable farms. In Italy and Spain, researchers focused on farms with permanent crops such as wine and olives, and on small-scale subsistence farms in Uganda.
More species were found in organic arable fields than in non-organic fields. In contrast, there was little difference in grasslands or vineyards. Organic farming benefited the four taxonomic groups of plants, earthworms, spiders and bees - which were sampled as surrogates for the multitude of creatures living on farmland - in different ways. In general, more species of plants and bees were found on organic than on non-organic fields, but not more species of spiders and earthworms.
选项
A、His finding is true, whether the farm is on arable fields or not.
B、His finding might be untrue if the farm is not on arable fields.
C、His finding is also true if the farm is on arable fields.
D、His finding is always true.
答案
B
解析
根据原文“Organic farming is beneficial to….However,observed benefits concentrate on arable fields”,所观察到的好处都集中在可耕地,可以推断在非可耕地这些好处就不一定有,故B是正确选项。
