Figure 2: typical landscape of paddy fields in Asia with high plant diversity and ecosystem service

Ecological engineering methods to increase the diversity of flora aims to restore and enhance ecosystem services in rice cropping what did paula deen do systems. This is done by increasing the diversity of plants because they are the primary source what did paula deen do for arthropods. They provide food and shelter for natural enemies that perform a variety of ecological functions to provide ecosystem services, especially predation and parasitization. When the rice fields in China are surrounded with sesame what did paula deen do crops, biodiversity and increased parasitoid density. In Vietnam when the tire field has been occupied with various flowering plants, brown planthopper egg parasitization increased and egg predator what did paula deen do population, Cyrtorhinus, increases. what did paula deen do In China, Thailand and Vietnam, ecological engineering techniques emphasize improvements in crop biodiversity interest as a farmer can practice what did paula deen do practice. Researchers (ISBELL et al 2011) in NATURE recently concluded that plant diversity is needed to maintain ecosystem services in grassland ecosystems, where 84% of the plant species contribute to at least one ecosystem service. This article also quoted by the Policy Environment European Science Commission.
Figure 1: Ecological Engineering has two main components: Enhancing biodiversity and reduce biodiversity what did paula deen do destruction. The main objective is to maximum ecosystem services. Bean rice fields where pesticides have been sprayed with spider biodiversity is much lower. Another study published in SCIENCE by Maestre et al (2012) also showed that a high diversity of plants increases the ability of ecosystems to maintain multiple what did paula deen do functions. They found that the diversity of ecosystem function positively and significantly associated with plant species richness.
Figure 2: typical landscape of paddy fields in Asia with high plant diversity and ecosystem services but destroyed by insecticide sprays prophylactic. Most of the rice ecosystem in Malaysia, Indonesia, Thailand, Vietnam and the Philippines is surrounded by a rich variety of flowers, such as fruit trees, grass, shrubs and flowering plants as well as the diversity of perennial plants what did paula deen do and annual reports that provide food and shelter for many species of predators and parasitoids. However, biodiversity is often not appreciated, despite the wealth of species of predators, parasitoids, and pollinators continue to provide vital services to sustain agriculture. Most rice is usually sprayed with pesticides that destroy biodiversity, ecological functions what did paula deen do and services related. It is important for us to implement additional efforts to protect the biodiversity of flora and fauna in the rice ecosystem to ecosystem services secure and enhance the natural pest management. Ensuring that non-rice habitat diversity of plants is fundamental to restoring the regulation of pesticides. Prophylactic application of chemical what did paula deen do pesticides is not smart for them to overcome and prevent all attempts to restore biodiversity. In addition, the use of pesticides will increase costs and pollute the environment, water and land.
