| Transgenic plants producing insecticidal protein derived from Bacillus thuringiensis (Bt) have been widely adopted since their commercial introduction in 1996. The widespread adoption of such plants has reduced use of conventional insecticides while attaining yield gains, thus providing economic, environmental and human health benefits. However, the benefits from Bt crops will be reduced or even eliminated if pests develop resistance to these toxins so that Bt crops are less or no longer effective. Although field resistance to Bt crops has not yet been found in the continental U.S., resistance to Bt sprays has been found in diamondback moth and greenhouse populations of cabbage looper. Hence, considerable attention has been devoted to developing management... |

| The dependency of small island economies on natural resources coupled with the pubic nature of these resources means that sustainability is a topical issue especially when development projects offer opportunities for "better living" for communities. For a mangrove dependent community of Pangaimotu in Vavau in Tonga tourism development offers better income from employment opportunities. Yet reclaiming mangrove areas for tourism development is likely to impact on fisheries resources that have traditionally been the main form of livelihood for the community. It is argued that for small island communities, whenever development activities ignore the critical role of mangroves on fisheries resources, the wider implications to the community are also overlooked.... |

| Forages are essential for the successful operation of animal production systems. This is more relevant to ruminants which are heavily dependant upon forages for their health and production in a cost-effective and sustainable manner. While forages are an economical source of nutrients for animal production, they also help conserve the soil integrity, water supply and air quality. Although the role of these forages for animal production could vary depending upon the regional preferences for the animal and forage species, climate and resources, their importance in the success of ruminant production is acknowledged. However with the increasing global human population and urbanisation, the sustainability of forage based animal production systems is sometimes... |

| ABSTRACT: Charcoal is an important product widely used in food preparation in many parts of the world, both in developing and developed countries. However, most of the time, the main qualitative characteristics for consumers and the environment are not considered during production. Developing energy-efficient products for food preparation has been a constant pursuit of the charcoal supply chain and the aim of this study was to interact with charcoal consumers to become conversant with and classify the characteristics suitable for barbecue use. To achieve our objectives, we used the quality function deployment (QFD) method. The qualitative needs were deployed together with a multidisciplinary team assembled through interviews with several charcoal... |

| The nature of agricultural production system in Indonesia is very diverse from shifting cultivation to intensive crop farming, from rain-fed to intensive-irrigated paddy field, from vegetables mix farming to monoculture industrial plantations, from subsistence small-scale farming to large-scale commercial plantation. As the fourth most populous country in the world that is inhabited by 250 million people, agriculture plays a substantial role in Indonesian economy which generates close to half of total employment and accounts for about a fifth of GDP, as well as the very important contributor of export. Notwithstanding the great potential resources and market demand, the sustainability of agriculture in the country remains challenging. The challenge is... |
