The Canadian marine fisheries are presently in the midst of a grave crisis. On both the Atlantic and Pacific coasts, fish stocks have been depleted through overfishing. Fish habitats are being damaged or permanently destroyed through industrial development. Gross overcapacity exists in both the primary and secondary sectors of the fishing industry, which is primarily attributable to the common property status of the resource. Many fishermen and processors have been or are in states of near bankruptcy as increasing energy costs, high product inventories and market weakness have crippled operations. A lack of alternative employment opportunities for many participants coupled with a high regional and community dependence on depressed resource-based industries has confounded attempts by government to introduce measures leading to more rational fisheries management. The outcome has been a strategy characterized as ‘incremental ad hocery’. Major inquiries were conducted into both the Atlantic and Pacific fisheries in the early 1980s. Conflict between and among the federal and provincial governments, various sectors of the commercial fishery, Indian and recreational usergroups, fishery interests and other industries, as well as Canada and other nations, has made it difficult to implement needed reforms. Stock and habitat maintainence and improvement; user regulations, coupled with tenure rights for fishermen; and marketing research and promotion are accepted as key components of any long-run fishery management strategy. In the short-run, the need is to develop approaches that are implementable in the context of diverse conflicting and vested interests. 相似文献

Part-time farming has to be considered important in the Federal Republic of Germany. Only one half of the agricultural holdings are presently farmed as full-time farms, occupying 77 % of the farmed area. The importance of part-time farming is not associated with the production of agricultural commodities, but is connected with the combination of farming and non-farming activities.In the Federal States of Baden-Württemberg and Saarland there exists a traditional interrrelationship between industry and part-time farming. Other regions, predominantly peripheral middle-range mountain areas with small farms and less favored natural conditions, form other concentrations. As local job opportunities are often non-existant, it means that daily long distance travel to reach off-farm places of employment is necessary.The income situation of part-time farmers can be considered satisfactory. Only 14 % are unable to earn their living entirely from non-farm earnings and consequently depend upon agriculture. According to statements made by part-time farmers their motivation to remain in farming is influenced by the compensation of working in a more natural environment. In view of the present (unsatisfactory) income situation of many small full-time farms, part-time farming is likely to increase in the future and to form a stable element in the agricultural structure of the Federal Republic of Germany. 相似文献

Part-time farming in the developing world: A case of Hobson's choice or the privilege of half a loaf
D. Christodoulou Dr. 《GeoJournal》1982,6(4):373-380
Existing international literature on part-time farming derives mainly from developed country situtations. The vast and heterogeneous developing world awaits documentation, analysis and interpretation. New approaches will also be required due to different conditions, such as overwhelming dependence on agricultural employment, skewed patterns of access to land and high levels of landlessness. Heritage is also different as are future prospects.Colonial economic management introduced constrained part-time farming. For the native population, poll taxes induced migration to plantations. The Hacienda system in Latin America provides a built-in system of dependent part-time farming. Capitalist farming has been spreading rapidly, sometimes fueled by land reforms, and has boosted the use of the vast class of small farmers, usually part-timers, as a pool of low-cost and docile labour.Trends are not re-assuring. Entrepreneurial agriculture tends to displace small holders from the land and to throw them on to the labour market while at the same time it generally lowers the employment capacity of agriculture through modernization of production. Parttime farming seems as unstable as ever and operates against a secular threat to the employment and income of the vast rural labour force. Part-time farming in the developing world merits deep probing and imaginative assessment. 相似文献

Fishery resources of north Norwegian waters are abundant and fishing is traditionally the prime occupation and basis of coastal settlements in that part of the country. Any solutions for regulating fisheries that are perceived as unjust by the coastal population are impracticable, as there are few natural or technical barriers to partication. Many coastal people have boasts and fish can be caught with cheap gear. In addition to keeping the actual harvest within sustainable limits and avoiding zero-sum competition among fishermen, a regulation system must also keep the right to fish open for the whole coastal population. The article compares alternative regulating systems: dualism or the currently practised 35/65 percentage share between offshore trawlers and coastal fishing boats, boat quotas, group quotas, company quotas, individual quotas, tradable quotas and area regulations. The author supports the idea of quotas for individual fishermen and strongly argues against any system that may lead to tradable quotas, as this will lead to marginalization of the coastal population. 相似文献

This paper seeks to root the analysis of part-time farming in the political-economic structure of agriculture and the larger economy. While part-time farming is not a new phenomenon, the growing prevalence of part-time farming in the US and other advanced industrial societies bears a strong relationship with the emergence of dualistic agrarian structures. Part-time farming has also been connected with the deconcentration of industry and employment. The political implications of the trend toward part-time farming are explored, with a conclusion that multiple jobholding, while nominally a proletarianization process, may in fact reinforce political conservatism in the countryside. The paper concludes by suggesting that future research on the political economy of part-time farming should place particular emphasis on the political implications of and sexual division of labour on multiple jobholding. 相似文献

Discusses the tragedy of the commons with regard to fish resources in the North Atlantic, and points to the fact that the Atlantic cod has now been so heavily exploited that a strong regulation of fisheries is needed to preserve an exploitable stock. The author argues for exclusive economic zones dividing up the remaining loopholes among coastal nations and individually transferable quotas. 相似文献

Lavas from the South Shetland Islands volcanic arc (northern Antarctic Peninsula) have been investigated in order to determine the age, petrogenesis and compositional evolution of a long-lived volcanic arc constructed on 32-km-thick crust, a thickness comparable with average continental crust. New 40Ar–39Ar ages for the volcanism range between 135 and 47 Ma and, together with published younger ages, confirm a broad geographical trend of decreasing ages for the volcanism from southwest to northeast. The migration pattern breaks down in Palaeogene time, with Eocene magmatism present on both Livingston and King George islands, which may be due to a change in both subduction direction and velocity after c. 60 Ma. The lavas range from tholeiitic to calc-alkaline, but there is no systematic change with age or geographic location. The compositions of lavas from the north-eastern islands indicate magma generation in a depleted mantle wedge with relatively low Sr and high Nd isotopic compositions and low U/Nb, Th/Nd and Ba/Nb ratios that was metasomatized by hydrous fluids from subducted basaltic oceanic crust. Lavas from the south-western islands show an additional sedimentary influence most likely due to fluid release from subducted sediments into the mantle wedge. Although magmatic activity in the South Shetland arc extended over c. 100 m.y., there is no evolution towards more enriched or evolved magmas with time. Few South Shetland arc lavas are sufficiently enriched with incompatible elements to provide a potential protolith for the generation of average continental crust. We conclude that even long-established subduction zones with magmatic systems founded on relatively thick crust do not necessarily form continental crustal building blocks. They probably represent only the juvenile stages of continental crust formation, and additional re-working, for example during subsequent arc-continental margin collision, is required before they can evolve into average continental crust. 相似文献

Hydroelectric development, forest exploitation, agricultural land use and related human population numbers have increased rapidly during the last 40 years, in the basin of the Nechako River, a major tributary system of the Fraser River. The Kemano project of the Aluminum Company of Canada Ltd. begun in 1950, was the largest industrial scheme in the area. A key feature of the first stage of it was a dam which diverted about 40% of flow of the south branch of the Nechako River, through a tunnel in the mountains, to the Pacific Ocean. In 1987 an agreement for the Kemano Completion Project (KCP), which would have diverted 87% of the flow, was signed. This final phase of the project would have put important fisheries resources of the upper Fraser River at high risk. Mitigation for fisheries protection were inadequate or untested in the system at the time. Potential cumulative impacts of water abstraction, elevated pollution levels, increased water temperature and natural sediment were not addressed. In January 1995 KCP was cancelled but there remain at present no adequate measures to protect the fish and the river ecosystem. These measures are to be negotiated in the future. Future management of the whole Kemano development must provide biologically realistic flow and temperature regimes in the Nechako River, and must deal with cumulative impacts of population and industrial growth. To achieve sustainability of fisheries in the Nechako River and upper Fraser watershed the present approach to the Kemano development must be changed fundamentally. The future of the Kemano development must be set in the context of the whole future of the upper Fraser system. Continued growth and development, as has occurred in the upper Fraser and total basin, can not go on without inimical changes to ecosystem conditions and loss of fisheries resources. 相似文献

This paper describes the development of a Livelihood Vulnerability Index (LVI) that estimates the relative ability of California commercial sea urchin fishermen to cope with the change associated with proposed marine protected areas. A key goal in establishing marine protected areas is to maximize conservation benefits while minimizing the potential negative impacts to local fishing communities. However, current impact analyses largely assume a linear relationship between percent of fishing area or revenue lost with the magnitude of impact to fishermen. The LVI described in this paper aims to provide an additional dimension to impact analyses in which the adaptive capacity of individual fishermen is examined to estimate the differential abilities of fishermen to cope with the loss of fishing areas or revenue. This paper advances vulnerability assessments as it develops a novel framework for identifying and measuring drivers of vulnerability for understudied fishing populations whose livelihoods depend upon marine resources. This vulnerability assessment is intended to inform the design of marine protected areas by enabling researchers to incorporate the adaptive capacity of fishermen into socioeconomic impact analyses. The LVI was developed for the California commercial sea urchin fishery in the context of proposed marine protected area networks develop through the California Marine Life Protected Act planning process. As climate change advances there is an increasing need to identify vulnerable and resilient populations and ways to bolster adaptive capacity given the environmental and economic changes ahead. 相似文献

Aquaculture currently provides half of all fish for human consumption, and this proportion is expected to increase to meet the growing global demand for protein. As aquaculture, including oyster farming, expands, it is increasingly important to understand effects on coastal ecosystems. The broad-scale ecological effects of oyster aquaculture are well documented; however, less is known regarding the influence of oyster aquaculture on sediment bacterial communities. To better understand this relationship, we compared three different oyster farming practices that varied in oyster biomass and proximity of oysters to the sediment. We used high-throughput sequencing and quantitative polymerase chain reaction to examine the effect of oyster farming on sediment bacterial communities. We examined the entire bacterial community and looked specifically at bacteria that support essential estuarine ecosystem services (denitrifiers), as well as bacteria that can be detrimental to human health (members of the Vibrio genus). We found that oyster biomass increased Vibrio richness and sediment carbon content, which influenced bacterial community composition. When compared to reference sites, the overall abundance of bacteria was increased by the bottom planting method, but the associated increases in denitrifiers and Vibrio were not significant. We were unable to detect V. parahaemolyticus, V. vulnificus, or V. cholera, the three most common Vibrio pathogens, in any sample, suggesting that oyster farming did not enhance these potential human pathogens in sediments at the time of sampling. These results highlight how differences in oyster farming practice can affect sediment bacterial communities, and the ecosystem services they provide. 相似文献

The ppaer re-examines three suggestions previously made concerning the colonization of the Krakatau islands since the extirpating 1883 eruption that involve the more recently emergent volcanic island Anak Krakatau, which itself suffered a devastating eruption in 1952. The suggestions re-addressed in the light of recent comments by other workers are:

| (2) | Anak Krakatau (with the Sertung spit) may have acted as an ecological refuge for open country species whose habitat on the three older islands declined as a result of vegetation succession. |
| (3) | Mainland open country species that did not colonize the archipelago when the appropriate vegetational successional stage occurred on the three older islands may now do so through a reopened early-successional window — Anak Krakatau (and the Sertung spit). |

Minitope coral islands represent one third of the islands located in the tropical Indo-Pacific. Subsistence farming and extensive agriculture dominate the traditional structure of income. As the lack of natural resources, infrastructure and capital restrict the developmental changes, the islands' natural environment has been utilized as economic potential. Planning and realization of land use systems introduced have, however, often been based on an insufficient data basis and have often inadequately considered the consequences of human impacts on the natural environment and its controlling factors. The result was environmental degradation and ecological destruction, affecting also the population's socioeconomic situation and in some cases rendering alternative land use impossible. Therefore, the long-term utilization of coral islands and, hence, the economic development of those countries require a specific development strategy. Based on the environmental and socioeconomic consequences of touristic utilization of coral islands in the Maldivian Archipelago, the model for a sustainable development strategy and its aims are derived, and the objectives, the conceptual structure, and the way of establishing them organizationally and administratively are presented. 相似文献

Fish diets play a critical role in our understanding of aquatic trophic dynamics and are an important component in developing ecosystem-based approaches to fisheries management. Although large nektonic fishes exert top-down predator effects on the food web and typically support viable commercial and recreational fisheries, little is known about the diet of this guild. We evaluated the diets (6327 stomachs) of four nektonic predatory fishes (Pomatomus saltatrix [78–395 mm], Cynoscion regalis [91–520 mm], Morone americana [156–361 mm], and Morone saxatilis [82–785 mm]) in Delaware Bay and in the adjacent ocean. To assess ontogenetic, geographic, and interspecific variation in diets, observations from individual fish stomachs were clustered into species-size class groups, and dietary overlap was estimated using multivariate analyses. A shift in diet composition, as well as diversity, occurred along the estuarine gradient and into the adjacent ocean. Some prey were shared by most predators, including some crustaceans (dominated by Callinectes sapidus, mysids, and Palaemonetes spp.), fundulids (dominated by Fundulus heteroclitus), engraulids (dominated by Anchoa mitchilli), and clupeids (dominated by Brevoortia tyrannus). However, inter- and intra-specific variation in diet was observed as well. In particular, M. americana consumed fewer engraulids and clupeids, and many more and diverse types of invertebrates, while P. saltatrix consumed more clupeids and less invertebrates. The lack of overlap in diet between the four predators evaluated, and between size groups for each predator, supports previous evidence that these groups feed in trophic guilds defined by species and by size within a species. The highly variable diets for these predators suggest high resolution spatial data are necessary in order to quantify their most important prey and their role in coastal ecosystems. 相似文献

The Petrology of Plutonic Blocks and Inclusions from the Lesser Antilles Island Arc 总被引：20，自引：12，他引：20
Three main groups of plutonic nodules are present in the LesserAntilles arc and are interpreted as (a) phenocryst clusters,(b) metamorphosed wallrock xenoliths and (c) cumulate texturedxenoliths. Large cumulate blocks display felsic-mafic layering,slump structures and auto-intrusive features. The majority ofspecimens are ad- and heteradcumulates with fewer ortho- andcrescumulates. Interstitial scoria and glass are present ina variety of samples. Plagioclase, amphibole, cino- and orthopyroxene,olivine, magnetite, biotite, ilmenite, quartz and apatite arepresent in various proportions in individual blocks. Plagioclaseand amphibole are modally predominant. Significant variationalong the arc is displayed in the rarity of orthopyroxene andabundance of amphibole in the southern islands compared withthe common presence of two pyroxenes in the northern islands. Plagioclase varies from An100–36 with very low orthoclasecomponent, and usually precedes amphibole in a given crystallizationsequence. Only on Grenada are plagioclase-free blocks present.Olivine is restricted to assemblages where coexisting plagioclaseis more calcic than An89 and its composition range is Fo90–59.Clinopyroxene is predominantly calcic augite and cinopyroxene,olivine and plagioclase all coexist stably with amphibole. Ageneral trend of decreasing Ca content in clinopyroxene fromsouth to north in the arc is present. Orthopyroxene ranges from En73–49 and is most common inassemblages where the coexisting plagioclase is more sodic thanAn83 Coexisting pyroxenes define temperatures in the range 800–1050?C. Amphibole compositions include pargasite, magnesiohastingsite,magnesio-hornblende and tschermakitic hornblende. The K contentof the amphiboles increases from north to south in the samesense as the general tholeiitic-calcalkalic-alkalic variationof parental magmas. Magnetite is the dominant spinel phase but ferrian chromiteand chromian magnetite are present in some Grenada cumulatesand pleonaste is found in rare St. Kitts samples. Ilmenite ispresent in blocks from several islands; coexisting Fe-Ti oxidesdefine a temperature range of 710?-950 ?C at of 15.5 to 10.0 bars. Biotite, quartz and apatiteare restricted to evolve cumulate types. Some modification of interstitial scoria/glass compositionsfrom equilibrium melts has occurred in the majority of samples,but general similarity with erupted lava types is importantevidence for the cognate relationship of the cumulate assemblages.The role of H2O is crucial in determining the calcic natureof island arc plutonic plagioclase when compared with relativelydry, layered tholeiitic plutons. Some modal and chemical featuresof cumulate-lava comparisons suggest plagioclase flotation maybe significant. A variety of thermodynamic calculations indicate temperaturesand pressures of crystallization in the range 850–1050?C, 4–10 kb. No evidence exists for systematic along-arcvariations in these parameters. Standard amphibole crystallinesolution models give unsatisfactory results for calculations. Some distinctive contrasts between cumulate and phenocryst modesare present. The abundance of amphibole in equilibrium withbasaltic melts in the plutonic situation compared with its rarityin lavas is striking. Plagioclase coexisting with a given meltis more anorthitic in the plutonic than the phenocryst mode. Least squares fractionation tests demonstrate the possibilityof relating basalt-andesite-dacite suites by fractional crystallizationof the cumulus phases. Trace element systematics of cumulate-lavasuites for individual islands also generally support this hypothesis.The suggestion of sole amphibole fractionation for the generationof andesite from basalt is discarded.

Part-time farming is a feature and a consequence of economic change which involves labour movement out of agriculture. It helps to sustain the rural sector by reducing the rate of outmigration. This paper reports on a pilot survey of part-time farmers in the S, Government-controlled part of Cyprus. The economy is growing rapidly with agriculture declining in relative importance although still contributing nearly half the value of exports. Over 50 % of farmers are part-time, meaning in this case they have another occupation. In general, farming is a minor activity and time spent in off-farm work is often increasing to maintain income levels. However the majority of the sample are keen to maintain their farming activity.In the Cyprus study part-time farmers appear slightly younger and operate smaller units than average; they rent in less land and irrigate a smaller area. Considerable differences are found between the four main agricultural zones; mountain, vines, dryland and coastal. At one extreme, exemplified by the coastal zone, commercial part-time farming provides a high standard of living on farms which are somewhat smaller than average. Off-farm work is available locally and complements farm work. Farmers' confidence in long-term prospects is reflected in their willingness (and ability) to invest on the farm and in their low levels of family, migration. At the other extreme, found in the depressed areas of the mountain zone, overt government policies may be required to ensure the continued existence of farming. The combined income of on and off farm work may be inadequate and farmers often have to borrow to meet basic household needs. These farmers travel long distances to find work and may have more than one off-farm occupation. Much of the burden of farm work falls on other family members. Although farmers would prefer to spend more time in agriculture they have limited confidence in its future prospects and recognize the possible necessity of outmigration. 相似文献

Agriculture has ceased to be the major employer in the rural areas of East Germany. Far-reaching structural change has resulted
in a sharp decrease in employment and the mono-structural character of villages has been lost. Unemployment is now a major
problem and women are worst affected. New jobs have been created in construction and elsewhere in the tertiary sector but
most people who have found new jobs have to commute to the towns or migrate permanently to the urban areas. A north-south
contrast has developed because the more developed network of towns in the latter, combined with a relatively good infrastructure,
has enabled many villages to survive as viable communities. An example is Fuchshain near Leipzig where employment with the
farming company (the former cooperative with 4200 ha of land) has declined but the population has grown through new housing
built for commuters. In the north there has been much depopulation and many houses are used as second homes. Either way there
is more conflict occurring now within rural communities because of tensions between the employed and the unemployed and between
old and new residents. It is therefore important that land use planning should take into account the changed economic and
social profiles and measures should be adopted to ensure that the countryside remains visually attractive and socially cohesive.

Sr-, Nd-isotopic and trace element data are reported for a suite of Marquesan volcanic rocks. These data complement earlier work on the island of Ua Pou and reveal that the marked shifts in source composition between shield-building and post-shield eruptives noted there are common to most islands in the archipelago. In addition, there appears to be a relationship between the magnitude of these shifts and the repose period between shield-building and post-shield activity such that, the longer the period of volcanic inactivity, the larger the isotopic and trace element differences between the two phases of volcanism. This, coupled with the compositional uniformity of the shield-building phase, and its close geochemical similarity to depleted mantle reservoirs, implies a strong lithosperic control on magmatic evolution: models invoking entrainment of asthenospheric material during plume ascent are not readily compatible with the observed time-compositional paths. Comparisons with other oceanic islands reveal two end member styles of temporal evolution, herein termed Marquesan and Hawaiian, and attributed to the interaction between the oceanic lithosphere and respectively weak and strong plumes, terms used to denote penetrative capacity and not necessarily size or buoyancy flux. Many other plumes may display characteristics intermediate between these extremes. The state of stress and temperature within the oceanic lithosphere in the region of an ascending diapir is also likely to exert a strong control on the geochemical evolution of OIB suites. 相似文献

This paper attempts to overcome the dichotomy between the broadly different and largely separate fisheries science and management (FSM) and ecosystem science and management (ESM) knowledge systems that characterise the international literature and are found in fisheries management practice in different countries. The paper argues that the construction of a heuristic we term the fisheries problematic, around issues and contexts, reveals the breadth of international fisheries management concerns and the variety of contexts in which these concerns are being faced. Adopting a political economy informed nature-society approach the paper considers ecological and socio-economic processes in their institutional settings in an attempt to shift from the either/or arguments around fish or ecosystems found in the FSM or ESM literatures to investigation that is grounded in understandings of the historically and geographically specific trajectories of fisheries related interactions and understandings of how knowledge about the trajectories and their interactions is fashioned. Drawing on recent conceptual innovations in the field, the paper develops a matrix-centred approach to explore ecological, industry, community and policy domains in New Zealand’s Quota Management System (QMS) and Individual Transferable Quota (ITQ) fisheries management regime. The extended framework prioritises scrutiny of the interaction amongst the four domains, as a strategy to help develop institutional frameworks that facilitate behaviours that are societally inclusive. The paper offers three conclusions. First, the landscape of New Zealand fisheries issues is very much a product of the contingent interaction of the QMS, a management regime designed around the principles of a FSM approach and laid down in a neo-liberal political environment and Maori aspirations encompassing the fisheries sector. Second, the conceptual mapping of FSM and ESM perspectives over New Zealand’s fisheries management experience highlights that a number of management issues have been down played by the commitment to FSM, a situation that has led to on-going tensions between commercial, recreational and customary stakeholders regarding fisheries management. Put another way, there is more to running a sustainable fishery (as defined in the Fisheries Act 1996) than QMS and other tools and dialogue about the development of these should be a priority. Third and more generally, improved dialogue on fisheries questions is likely to be most expeditiously advanced by studies that explicitly conceptualise and contextualise ecological and socio-economic processes and their institutional arrangements. 相似文献

Although agricultural work is declining in Hungary, farming remains an important source of employment. However, the agrarian
population should not be regarded as homogenous because many small farms are worked only for subsistence and family income
supplement. This is because of prolonged economic crisis which makes for a shortage of job opportunities in other sectors
of the economy. Until economic growth accelerates there is a need for transitional solutions to the problem of unemployment.
It is argued that the present farming system could be diversified through labour-intensive programmes to provide piped water
and drainage in small towns and villages and simultaneously engage many of the long-term unemployed who are no longer entitled
to benefit and lack the qualifications for jobs that require special skills. The environment could also be protected by the
afforestation of 300–400 000 ha of arable land or its conversion to grassland. Light industry could also generate employment
while stimulating the growth of local farm production and the improvement of the infrastructure. Training for unemployed young
people should also be a priority if the erosion of rural labour resources is not to become irreversible. A much more proactive
approach is needed from government to safeguard rural labour resources and achieve greater integration between forestry, farming
and processing.

This study assesses the condition of the fishing industry in Pakistan. It briefly reviews the ecological environment of Pakistan's
fisheries and describes recent developments in technology and their impact on the catch. The factors contributing to growth
include government efforts, fleet expansion and development of export markets. This study also points out the difficulties
in arriving at a satisfactory management policy for the regulation of the industry. Development strategies seek rational,
efficient exploitation of marine resources for the broad goals of national development. Consequently, policy makers' fisheries
management concepts and techniques are generally less effective in addressing the need of the coastal communities. The conclusion
is that fisheries development effort need balanced resource management, serving as an instrument for regional development
while taking into account the traditional resource use rights of small-scale fishermen. 相似文献
