Abstract The increased tempo of developments in biopesticides is closely related to the growing awareness and emphasis on integrated pest management (IPM) and sustainable agriculture. Several economic forecasting sources predict a growth rate for the biopesticide industry at 10 to 15% per annum over the next 10 years in contrast to a 1 to 2% growth rate for synthetic chemical pesticides. The greatest opportunity for biopesticides is in the insect pest management arena. This paper discusses several types of bioinsecticides that may have significant economic impact in the coming years. 相似文献

While mineral exploitation can provide significant income and employment, it may negatively impact the environment, being ultimately detrimental to livelihoods in the long term. The consequences of mining are of concern in high value forest ecosystems such as the Sangha Tri‐National (TNS) landscape covering Cameroon, the Central African Republic and Republic of the Congo. This paper captures the socio‐economic and environmental impacts of small‐scale mining in the TNS. Using structured questionnaires, consultations and observation, diamonds and gold were found to contribute directly to the livelihoods of at least 5% of the landscape's population. Although up to eight income‐generating strategies are used, mining contributes on average to 65% of total income and is used mainly to meet basic needs. A gold miner's average income is US$ 3.10 a day, and a diamond miner earns US$ 3.08, making them slightly wealthier than an average Cameroonian and three times wealthier than an average non‐miner in the TNS. Environmental impacts were temporary, low impact and of limited scale. However, with mining likely to increase in the near future, an increasing population and miners' low environmental awareness, measures are needed to ensure and reinforce the positive impact of artisanal mining on livelihoods and maintain its low environmental footprint in the TNS landscape. 相似文献

Lack of technology and efficient management of solid waste coupled with poverty have motivated most developing countries to
sort for cheap waste disposal methods with negative consequences on the environment. Open burning at waste dumps causes serious
toxicological impacts. Most organic solid waste excluding plastics when burned cause considerably little environmental pollution.
However, non-stoichiometric combustion of waste plastics produces significant amounts of various aliphatic and aromatic compounds,
acidic gases, dust and smoke. These products pollute the air, water and soil generating significant health problems with related
socioeconomic impacts on human, animals and plants. Some of these pollutants are toxic and/or carcinogenic, form acid-rain
and influence climate change. Critical discourse and research on environmental toxicology resulting from air pollution with
related health risk and impacts have been catalysed by the enactment of major environmental regulations and increased awareness.
The new clean air act amendment of 1990 is estimated to require about $25billion annually for its implementation in the United
States, indicating the gravity of the pollution problem. Understanding, controlling and mitigating the impacts of chemical
pollution from multiple sources related to open burning of plastics is complex. This paper uses content analysis of relevant
literature and field observations to analyse, evaluate and identify characteristic pollutants including their transmission
potentials, sources and impacts on human health with the assessment, prevention and management of related risk. An affordable
technology-based approach applied within a bottom-up management strategy to prevent and control pollution offers a sustainable
solution underpinned by resource and energy recovery from waste. 相似文献
