Nature-based marine tourism in the Gulf of California and Baja California Peninsula: Economic benefits and key species

Ecotourism can incentivize social and environmental benefits through marine conservation, in parallel with efforts to better manage fisheries, coastal development, and other human pressures. In Mexico's Gulf of California and Baja California Peninsula (GCBP), marine ecosystems support tourism activities in many communities, but to date there have been no region-wide studies to estimate their benefits or identify key species. Based on data collected in this study, each year nature-based marine tourism in the GCBP results in 896,000 visits, US$518 million in expenditures and at least 3,575 direct jobs from formal operations. In interviews with operators, over 40 species groups were named as important; sea lions, whale sharks, whales, and marlin were the highest ranked, highlighting the importance of ecosystem-wide health for nature-based tourism sustainability. Local employment and the ability to make economic and conservation goals compatible were noted by operators as significant opportunities provided by nature-based marine tourism; challenges included pollution and declines in ecosystem health, a lack of infrastructure, poor resource management policies, and high operating costs. As nature-based marine tourism expands, a wider transition to true ecotourism, a focus on equitable benefits and collaboration between stakeholders and a cross-scale and ecosystem approach to management will be vital for achieving potential sustainable social, ecological and economic benefits.     

煤炭产业物质流核算的指标体系构建研究

循环经济落实到实处,不仅需要从技术端不断推进新技术在生产活动各领域的应用,更需要一个整体的资源和能源管理体系.物质流核算即是通过对国家、地区或产业的实物流的核算,理清资源和能源使用过程.通过针对循环经济发展较为成熟的煤炭产业进行物质流核算的指标体系构建,找到一些建立物质流核算体系的思路,并提出具体政策建议.

Modelling the economic consequences of the EU Water Framework Directive for Dutch agriculture

The EU Water Framework Directive (WFD) requires member states to take measures to ensure that bodies of water will be in good chemical and ecological condition by 2015. Important measures to achieve this goal include reducing emissions of nitrogen (N) and phosphate (P₂O₅) from manure and mineral fertilizers into the environment. In regions with a high livestock density, this measure is expected to affect agricultural production and income. To quantify these effects, an environmental economic model is required that can assess alternatives capable of reducing N and P₂O₅ potential emissions to water. In this paper, we develop a model that is capable of analysing changes in potential emissions to water of N and P₂O₅ and apply it to the Netherlands, a country with large nutrient emissions. Compared to a 2015 reference scenario based on current efforts to reduce nutrient emissions, we found that the WFD measures will increase regional transport and export of manure and reduce the number of animals in the Netherlands. Fodder adjustments (defined as lower N and P₂O₅ input in purchased fodder) to decrease nutrient excretion in manure were a less attractive option than amongst others export, transportation of manure to another region, land use changes or reduction of the number of livestock. Compared to the reference scenario in 2015, total agricultural income will decrease by about €81.5 million per year (about €49/ha per year), although the effects will differ among parts of the Netherlands and agricultural sectors. The average predicted decrease in N emissions from agricultural sites, vulnerable to leaching into bodies of water will be almost 20% or approximately 14.7 kg N/ha per year. The reduction in N emissions to air from animal sheds, manure storage systems, application of animal manure and mineral fertilisers to the crops and grazing animals equals 6.5% or 5 kg ammonia (NH₃) per hectare.     

The LIFE certification methodology as a diagnostic tool of the environmental management system of the automotive industry

We conducted a diagnosis of the environmental management system of the Brazilian auto parts industry, using the LIFE certification methodology (lasting initiative for earth) as a diagnostic tool. This certification recognizes enterprises that develop conservation actions for biodiversity for the purpose of minimizing and/or mitigating their own negative impact on the environment. Through this method, it was possible to quantify and qualify the environmental impact and investigate the existence of conservation actions, as well as evaluate them quantitatively and qualitatively. Therefore, we used this methodology to demonstrate its potential as an economic instrument of environmental management through its application within an EMS certified to the ISO 14001 series. It was shown that there are many benefits of using sustainable environmental resources (possibility to return to ISE-Corporate Sustainability Index-Bovespa) and for the final disposal of waste from production. The main results indicated that the LIFE methodology allows companies to incorporate actions to biodiversity conservation transversally into their EMSs, which can increase the efficiency of enterprise management. We believe that the use of this management model by other companies will enable the intensification of conservation actions in protected areas in their regions.     

绿色消费模式与循环经济相关性的探讨

绿色消费是循环经济在消费领域的具体形式,它要求人们的消费活动必须有利于环境保护、资源利用和人的整体素质的提高。绿色消费模式是人类发展模式的一次历史性转变,是一种人与自然相互协调的消费观,既强调消费的重要作用,又强调消费和再生产其他环节与环境的动态平衡,有利于取得人类社会和自然的协调发展。     

Environmental protection, the economy, and jobs: national and regional analyses

The relationship between environmental protection (EP), the economy, and jobs has been an issue of harsh contention for decades. Does EP harm the economy and destroy jobs or facilitate economic growth and create jobs? We address this issue by summarizing the results of the Jobs and the Environment Initiative, research funded by nonprofit foundations to quantify the relationship between EP, the economy, and jobs. We estimate the size of the US environmental industry and the numbers of environment-related jobs at the national level and in the states of Florida, Michigan, Minnesota, North Carolina, Ohio, and Wisconsin. This is the first time that such comprehensive, detailed estimates have been developed.     

Impacts of arsenic contamination in groundwater: case study of some villages in Bangladesh

The contamination of groundwater in Bangladesh by arsenic is a widespread and serious environmental problem, affecting mainly the rural population who rely extensively on groundwater for drinking and cooking. The study conducted survey work in a few affected villages of the Northwest region in Bangladesh. The household survey gathered information on the respondents (affected by arsenic) water usage and sources, knowledge of the arsenic problem, changes in the source of water for drinking and cooking, arsenic mitigation technologies and socio-economic information on the households. The survey work shows that percentage of male patient is higher than female patient among the same level of household income in each study villages. Prevalence of arsenicosis is more among poorer sections and it is directly related to the poverty situation of the community. People know more about the health problems caused by arsenicosis but lack knowledge about mitigation aspects. In one of the study areas, every year an extra 4% tubewell is getting contaminated by arsenic. Arsenic contamination in groundwater also affects the environment and the ecology negatively. The NGOs have been found contributing to a knowledge creation process in the village community as the villagers are showing marked behavioral changes in water-use practice.
