澳大利亚农业系统中非点源污染的控制   总被引:1,自引:0,他引:1  
C. GOURLEY  A. RIDLEY 《土壤圈》2005,15(6):768-777
The Australian farming sector is continuing to intensify, particularly within 300 km of the east and southern coastlines. In the future there will be fewer and larger farms, which will use more fertilizer, support more stock, grow more monoculture crops, and utilise more marginal soils. This is likely to increase the major environmental impacts of soil degradation, salt, nutrient and sediment contamination of waterways, and greenhouse gas emissions. Australian national water policy continues to focus on land, stream and groundwater salinity issues, although there is now a greater recognition of the importance of nitrogen and phosphorus losses from agriculture. The general philosophy of policy for dealing with nonpoint source pollution has been towards a voluntary rather than regulatory approach, with state and national governments supporting a range of programs to encourage sustainable agricultural practices. A catchment (watershed) based approach, through the use of integrated catchment management plans, is the primary way that non-point source pollution is addressed at the farm and local level. At an industry level, cotton, grains, meat, sugarcane and dairy amongst others, as well as the Australian fertilizer industry, have responded to non-point source issues by investing in research and development, and developing codes of practice aimed at abating these environmental impacts. Understanding the economic, social, political and cultural contexts of farming as well as the environmental impacts of agriculture are very important in determining the appropriateness of policy responses for Australian farming systems.  相似文献

Systematic reviews of agricultural safety and health interventions have shown little evidence of effectiveness. In this study, we used a self-documentation and collaborative interpretation method (cultural probes, n = 9) as well as farm interviews (n = 11) to identify factors affecting the adoption and implementation of safety information. The three main barrier groups found were (1) personal characteristics of the farmer, (2) limited resources to make safety improvements, and (3) the slow incremental evolution of the physical farm environment where old, hazardous environments remain along with new, safer improvements. The enabling factors included good examples or alarming (and thus activating) examples from peers, ease of implementation of the promoted safety measures, and enforcement of regulations. The findings suggest that a user-centered approach could facilitate the development of more effective safety and health interventions. A conceptual model of the safety intervention context created in this study can be used as a framework to examine specific barriers and enabling factors in planning and implementing safety and health interventions.  相似文献

"Agricultural at Risk: A Report to the Nation" is a proceedings document of a three-year (1987-1990) policy development process entitled "Agricultural Occupational and Environmental Health: Policy Strategies for the Future." That process culminated in the emergence of occupational health and safety in agriculture as a public health policy issue in the U.S. Several agricultural health and safety programs evolved as direct or indirect consequences of this process, including, but not limited to, the NIOSH agricultural occupational health programs, The Kellogg Foundation agricultural health grants programs, and the prospective chronic health studies of pesticides (EPA-NlH funded). The Agriculture at Risk report resulted in 86 specific recommendations. The authors of this article reviewed each of these recommendations and rated them on a subjective scale as to their degree of attainment. They found that 44% of the recommendations had received moderate to substantial action. Most of the positive action was in the areas of research and coalition building. A noticeable lack of action was in the areas of standards and regulation, occupational health service delivery, and education categories. This article concludes with an analysis of the limitations of the AAR report, changes in exposed populations over the past decade, and specific recommendations on future actions to address the issues.  相似文献

Efficient mechanisation is a major factor underlying the high productivity and low cost of most Australian crop production systems. Efficiency has generally been associated with greater work rates, achieved by using equipment of greater power and weight. This trend has continued until very recently, despite a reduction in tillage for weed control.

Scientists have warned of erosion and soil structural degradation caused by tillage and traffic, but tillage, rather than field traffic was seen as the major problem, and reduction of tillage as the solution. Reduced tillage has provided major benefits, but adoption has occurred slowly and sustained zero tillage is still rare, except in controlled traffic farming systems.

The first part of this paper presents research evidence of the direct cost, practical impact and long-term effects of wheel traffic on cropped soil. Direct cost is associated with the energy requirements of disturbing wheeled soil. Practical impact occurs as a result of the lost opportunities and additional operations associated with wheel ruts. Long-term productivity and environmental impact occur because wheel traffic reduces plant available water and increases runoff and erosion.

In controlled traffic all equipment wheels are restricted to compacted permanent traffic lanes, so that soil in the crop beds and traffic lanes can be managed respectively for optimum cropping and optimum trafficability. Controlled traffic farming recognizes the symbiosis between controlled traffic and zero tillage in providing opportunities for more productive and sustainable farming of soil uncompromised by wheel effects.

The beneficial effects of controlled traffic have been demonstrated in widely different soils and mechanisation systems (e.g. Australia and China), and it has been vigorously advocated in both the USA and Europe, but large-scale adoption has been rare. The second part of this paper discusses cropping system response to controlled traffic farming, and the program which led to large-scale adoption in Australia. This happened first in extensive grain production, but adoption has since occurred in many Australian farming systems, supported by the availability of high-precision field guidance systems and a greater range of compatible equipment.

Controlled traffic farming reduces soil degradation and the energy requirements of cropping. It is also more productive, and its practicality and economic viability have been clearly demonstrated in enthusiastic farmer adoption, and the formation of an Australian Controlled Traffic Farming Association.  相似文献

ABSTRACT

Most of the materials on hearing loss due to noise in the agricultural industry are training and research-oriented materials in the form of brochures, manuals, and journal articles, published by academic presses, government associations, and professional organizations, respectively. Few books are entirely devoted to the topic of hearing loss in agricultural settings. Recently, many occupational and safety Web sites have been adding information and links to publications dealing with hearing loss in the agricultural industry. This Webliography represents the author's best efforts to briefly describe some authoritative Web sites with information targeted to individuals interested in farm occupational hearing loss.  相似文献

Many Australian cotton farmers are interested in using organic waste products such as composted cotton gin trash as soil amendments because of perceived benefits to soil health and the environment. However, detailed information on the relative benefits and costs involved is not readily available to cotton growers who farm on clayey Vertisols. The objective of this study was to quantify soil changes in a farmer-established trial to evaluate the potential benefits of applying composted cotton gin trash and/or lime to a Vertisol. Selected soil properties were measured in an experiment located on a commercial cotton farm near Goondiwindi in southern Queensland, Australia. Cotton gin trash compost improved potassium availability and soil microbial biomass in soil, whereas lime improved only the latter.  相似文献

Tillage systems and soil properties in North America   总被引:6,自引:0,他引:6  
This paper reviews current knowledge on the range and extent of various tillage systems used in North America with special reference to the effects on soil properties, the erosion hazard and water quality. The increasing adoption of conservation-tillage systems since their introduction in the early 1960s follows an enhanced awareness of the increasing risks of soil erosion and non-point source pollution and the high cost of fuel with conventional tillage. Most “conventional tillage” systems encompass complete inversion tillage along with several secondary and tertiary tillage methods. In contrast, conservation-tillage systems involve streamlining various farm operations, thereby reducing the frequency and intensity of the soil manipulative operations. Reduction in tillage intensity has been accompanied by the development of rotations and cropping systems, methods of surface and internal drainage, fertilizer technology and pest management alternatives.

The status of antecedent soil physical properties is an important factor affecting the choice of tillage systems. Important soil physical properties governing the choice of tillage systems include soil wetness and anaerobiosis, soil temperature and soil structure including its susceptibility to compaction, crusting or erosion. Tillage systems affect soil physical, chemical and biological properties. Among drastic tillage-induced changes in soil properties are bulk density, infiltration rate, aggregation and aggregate size distribution, soil organic carbon and nutrient profile, microbial activity and species diversity, and the population of earthworms. Macropores and biochannels are usually more prevalent in conservation-tillage than conventional-tillage systems. Conservation tillage induces stratification of soil organic matter and related nutrients, enhances the activity of soil fauna and leads to acidification. The magnitude of these changes depends on the soil type, the cropping systems and the type of conservation tillage adopted. Soil organic carbon and nutrient stratification are generally more pronounced in coarse-textures than in clayey soils. Conservation tillage is also associated with greater biomass pool size. The latter affects the nutrient response curves of the soil. Nitrification and denitrification are other important processes affected by tillage systems.

The widespread adaption of conservation-tillage systems, although beneficial in controlling off-site sedimentation, has raised concerns about the potential for increased leaching of nutrients and pesticides to groundwater. Important pollutants associated with conservation tillage are nitrate and pesticides. Some studies have shown little effect of tillage on losses of pesticides. Conservation tillage may suppress crop yields, especially on heavy textured soil with poor internal drainage and in those prone to soil compaction caused by vehicular traffic.  相似文献

Discussions with groups of North Carolina farmers identified farm vehicle public road safety as their primary occupational health and safety concern. Findings of a mail survey of North Carolina growers participating in a North Carolina Department of Labor migrant housing inspection program indicated that over 97% of them felt less safe on North Carolina public roads now (1999) than five years prior (1995), and over 79% currently (1999) felt unsafe transporting farm vehicles on North Carolina public roads. Using both primary and secondary data, we explore the context of farm vehicle public road crashes, identify contributing individual and environmental risk factors, and estimate the public health cost. Recommendations and suggestions for future farm vehicle public road safety research and interventions are proposed.  相似文献

目前我国土壤和农作物中有毒物质的残留问题日趋突出。有机氯农药虽已禁用近20年,但通过某些食物链富集仍可对人体健康产生威胁。此外,残留农药的种类和数量逐年增加,其中有机磷农药问题尤为突出。重金属残留超标主要集中在大中城市郊区、污灌区和矿区农产品,尤其是城郊蔬菜中重金属污染问题比较突出。硝酸盐积累主要在农业集约化地区,尤其是塑料大棚等保护地问题比较普遍。农产品中的有机氯残留、重金属残留以及硝酸盐积累均与土壤污染有密切的关系,土壤是影响农产品质量安全的源头因素。因此,为了保证农产品质量安全,应尽快开展全国土壤环境质量调查与评价,建立长期性的土壤环境质量监测网络,并加强土壤中环境激素类的研究和监测,修订土壤环境质量与农产品质量标准,建立基于污染物生物有效性的环境质量标准体系与评价方法。同时制订土壤质量修复和保护规划,并完善有关立法,实现土地资源由数量管理向数量与质量管理并重的战略转变。  相似文献

Precision Agriculture (PA) has been advocated as a promising technology and management philosophy that provides multidimensional benefits for producers and consumers while being environmentally friendly. In Europe, private stakeholders (farm advisors, farm equipment producers, decision support providers, farmers) and research institutions have been trying to develop, test and demonstrate adoption of precision agriculture solutions with governments financing big projects in these areas. Despite these efforts, adoption is still lagging behind expectations.

Whether farmers adopt PA or not is likely to be influenced by several factors. This study intends to identify the main socio-economic determinants of adoption of precision agriculture in Denmark and Germany employing a binary logit model on a cross-section survey data. The results show that farm size, farmer age and demonstration and networking events like attending workshops and exhibitions significantly influence farmers’ adoption decision.  相似文献

In 1999, project leaders from seven states (i.e., Iowa, Kansas, Minnesota, Nebraska, North Dakota, South Dakota, and Wisconsin) began to share ideas and resources for providing behavioral health assistance (i.e., mental health counseling and addictions services) to stressed farmers, ranchers, farm workers, and their families. The seven states are among those most impacted by the farm crisis of the 1980s and again by low commodity prices and disasters such as droughts and floods in the 1990s. Project leaders conferred in monthly telephone conference calls and by 2001 began meeting in semi-annual face-to-face meetings to formally agree on a mission, program components, and management structure. Administrative functions were transferred from the Wisconsin Office of Rural Health and Wisconsin Primary Healthcare Association, to AgriWellness, Inc., a regional nonprofit corporation founded to provide technical assistance, grant writing, training of service providers, and other administrative supports. The Sowing the Seeds of Hope program has become a model for the provision of behavioral health supports for the agricultural population, including development of farm stress telephone hotlines, provision of confidential and affordable outpatient mental health and substance abuse counseling, training of professional providers in agricultural behavioral health, training of indigenous farm and rural residents as outreach workers who can respond to disasters of all types, and weekend educational retreats for farm residents. The program has achieved economy of scale by sharing expertise across state boundaries and the formation of a regional administrative structure. Yet, many challenges exist, the greatest of which is obtaining ongoing permanent support for the increasing numbers of uninsured and underinsured people involved in agriculture.  相似文献

Hired farm workers provide the majority of the workforce for California's labor-intensive agricultural sector Agriculture is one of the most hazardous occupations, but there has been little research into the etiology of poor health outcomes that occur disproportionately in hired farm worker populations. MICASA is a cohort investigation of occupational and environmental health risks in hired farm worker households in Mendota, California, that employed a two-stage sampling process, including random selection of census blocks and door-to-door enumeration. The aim of this analysis was to evaluate the success of the sampling process and compare demographics of the enumerated population to other regional samples of Latino populations. In the enumeration, 1257 addresses were mapped and 729 hired farm worker households were enumerated. Findings showed no significant differences between the enumerated population and the resulting MICASA study sample; however, the MICASA population was more likely to be male, from Central America, work in agriculture, and have fewer years residency in the U.S. than California Health Interview Survey (CHIS) respondents. Additionally, 9.4% of the enumerated dwellings were back houses or unofficial dwellings and may have been missed by the U.S. Census 2000. Demographic comparisons between the enumerated population, census data, and CHIS data highlight the differences in these sampling methods and suggest possible demographic changes in hired farm workers in California. While difficulties in accessing hired farm workers often account for the lack of population-based research, the MICASA cohort provides an opportunity to examine occupational health patterns relevant to other farm worker populations.  相似文献

The purpose of this study was to evaluate the effectiveness of two regional multi-disciplinary farm health fairs, pairing cardiovascular and agricultural health and safety risk factor assessments and education, in agricultural regions in southern Minnesota in 1999 and 2001. This study explores the rationales and motives cited as having an influence on: (1) work practice and lifestyle adaptations, (2) resistance to such changes, and (3) compliance with health fair recommendations. Evaluation took the form of standardized telephone surveys and callbacks with an open-ended component administered by a parish nurse interviewer and conducted six months following each of the fairs. Participants had received individualized work practice and lifestyle recommendations based upon their medical results and questionnaire responses. Of the 378 total attendees at the two farm health fairs, 272 (72%) participated by filling out on-site questionnaires, and 284 (75%) completed a post-fair interview. Participants who were actively farming totaled 237 (63%) of all participants. A majority of those interviewed on callback (78%) reported either work safety or lifestyle changes, while 47% of those actively farming claimed varying work safety changes as a result of the fair. The conclusions drawn from the follow-up interviews include: (1) the two farm health fairs resulted in a substantial number of participants positively modifying lifestyle and work practices, (2) the stand-alone farm health fairs were effective in attracting farmers, and (3) low-level stressors identified in the participants could be effectively addressed by knowledgeable rural health care resources such as parish nursing.  相似文献

There is an increasingly well‐founded understanding of the chief drivers and constraints to widespread adoption by Australian landholders to practices to manage dryland salinity. However, each specific situation depends on a range of biophysical, social and economic factors. Such is the case in this study that examines farmers' salinity management in the Wallatin‐O'Brien catchments in the low‐medium rainfall zone of the Western Australian wheatbelt. The study involved interviews with landholders and economic modelling of representative farms and salinity management options to gain an understanding of the farmers' adoption behaviour regarding salinity management. Most landholders interviewed saw dryland salinity as a second order farm management issue, due first to the relatively slow rate of expansion of saline land within the catchments and second, because the changes in land use required to prevent further loss of land to salinity were viewed as being uneconomic. The exception to this was the minority (<15 per cent) of farmers in the catchment that have most of the saline land and have experienced most of the recent increase, and for these farmers (primarily located in the valley floor) salinity is a pressing issue. The scale and pattern of isolated outbreaks on adjacent slopes means that salinity is merely a nuisance problem for farmers who only have this type of salinity. For all farmers, a disincentive to invest in salinity management was the landholders' lack of knowledge about the proper placement, needed scale of adoption and economic viability of salinity management options. Saltland pastures, surface water management and lucerne were viewed positively, with several desirable characteristics such as ease of trialling and complementarity to existing farm practices. By contrast, engineering options such as deep drainage, where considerable investment is involved and disposal of groundwater is problematic, were rated less favourably. Bioeconomic modelling of these salinity management options generated results that largely confirmed the merits of what landholders in the catchments currently do. The findings showed that there was little economic merit in wide‐scale adoption of these salinity management options in these catchments. However, the findings did highlight the need to match salinity management options to a farm's particular circumstance, if best use of the options is to be made by the different farms in the catchments.

This study analyses the influences of sociodemographic factors, business orientation of farmers, and farm characteristics on adoption of ICT-based information through primary data collected from 461 farmers in eight districts of Uttar Pradesh, India. A personal interview survey was conducted using a pre-tested structured questionnaire. The Poisson Count Regression Model was used to analyze the factors influencing use of the information derived through ICT-based systems on various agricultural practices. The findings indicate that education, income, and social category of farmers are important sociodemographic factors affecting the adoption of ICT-based information systems. Similarly, farmers who consider farming as a business venture, practice a diversified cropping system, and have small farms are more likely to use ICT-based information.  相似文献

Farm-related fatalities are a significant problem in Australian agriculture. Over the period 2001-2004, there were 404 fatalities that occurred as a direct consequence of visiting, residing, or working on a farm. This study employed a human capital approach to establish the economic costs of farm-related fatalities to the Australian economy. Modeling of direct and indirect costs associated with farm-related fatalities estimated that the 404 traumatic deaths over the period 2001-2004 cost the Australian economy $650.6 million in 2008 Australian dollars (AUD). This equates to 2.7% of the 2008 farm gross domestic product (GDP) due to potentially preventable farm accidents and injuries. Farm-related deaths are a significant economic cost to the Australian economy. Greater resources need to be directed to farm health and safety interventions to increase their effectiveness at reducing the risk exposure of those visiting, residing, and working on Australian farms.  相似文献
