Farming as a livelihood source for the urban poor of Nakuru, Kenya

Farming among urban dwellers in Sub-Saharan Africa is a common phenomenon. The present study, carried out in a medium-sized town in Kenya, not only confirmed this but also showed that farming by urban dwellers in the rural areas was even more important for these households’ livelihoods than farming in town. However, those who could benefit most from farming, i.e. the urban poor, appeared to be underrepresented among urban farming households and those urban poor who did farm, either in urban or in rural areas, performed worse than the farming non-poor. The importance of farming as a livelihood source is illustrated by the fact that in years with very little or no harvest due to drought, many of the poor farming households faced food shortages.     

Positive aspects of part-time farming in the development of a professional agriculture: Remarks on the Italian situation

Part-time agriculture is a large, well-developed and persistent phenomenon in Italy. But this is not well known. This paper takes into consideration the Italian literature on part-time farming (PTF) to find a satisfactory definition. The author deals with general problems of rural development, looking at PTF (especially in farm-based households) as a structural phenomenon. The article suggests the farm family instead of the individual farm operator be the unit of analysis and provides new data and estimates based on official statistical sources from 1961 through 1975. There are different typologies of PTF situations according to the internal and external conditions of the family's holdings: transitional PTF, which involves rural and poor families working for domestic production. This type is a form of subsistence farming which attracts State subsidies and public income transfers; accessorial PTF is a form of autoconsumption concerning different families' members. It is generally used to increase family income (sometimes farming is a secondary activity for people employed outside agriculture); professional PTF, based on the family holding's central role, which is a rational way of farming. This last kind of PTF is sometimes more productive, modern (ready of the introduction of innovations) and more competitive than full-time farming: this element could have important implications for the rural development policy in the industrialized countries.     

Part-time Farmig in Hungary

Part-time Farming in Hungary plays an important role in agricultural output. It provides 1/3 of gross production, half of the pork production and the majority of such intensive products as wine, fruits and berries, honey, etc. Part-time Farming has two basic forms: the household plots of collective farm members and employees and the small private farms of non-agricultural population. Half of the Hungarian families have such a farm activity, which is largely encouraged by the government. The flexible intregration of large scale (collective) farming and the private part-time farming was one of the keys in the recent agricultural successes of Hungary.     

Part-time farming: The Cyprus case

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.     

A behavioural analysis of hop farming in Hereford and Worcestershire

Behavioural studies in agricultural geography are comparatively rare, and this paper demonstrates the importance of the satisficer concept of economic behaviour when examining patterns of hop production in the West Midlands. The main farm and farmer characteristics of the hop growers are outlined before attention is focused on the relative importance of physical, economic and socio-personal factors in the decision-making process. Whilst economic factors dominate the ranking, socio-personal factors have a significant effect on the hop growers' decision-behaviour. Opportunity cost and social inertia are forwarded as important concepts in accounting for patterns of hop farming and a multivariate analysis emphasized the complexity and individuality surrounding farmers' decision-making behaviour. Differences in attitudes and behaviour are shown to be related to variations in the hop farmers' personality and rationality and to differences in their age, education, experience and traditions.     

Environmental Constraints and Part-time Farming in Southeastern Nigeria

In southeastern Nigeria where population pressure is a problem of accelerating importance the agricultural land is in short supply thereby necessitating off-farm jobs to supplement farm income. There is therefore, a high incidence of part-time farming in the region. Analysis of the operational characteristics of thirty-six villages confirms that the intensity of part-time farming varies spatially according to the severity of environmental degradation resulting from population pressure. In addition, villages around urban/industrial centres participate actively in part-time farming since opportunities for off-farm employment are relatively higher. The situation in southeastern Nigeria is used to illustrate the prospects and problems of part-time farming in a developing economy. The implications of part-time farming on the agricultural economy and on rural development generally are examined. Policy measures are suggested that will direct the co-existence of part-time farming with work in the off-farm sector in order to achieve a beneficial and integrated rural development.     

Large-scale farming as a cultural dilemma in U.S. rural development— The role of capital

Although agressive economic traditions have benefited U.S. agricultural fortunes enormously in the past, expanding farming scale now also seriously threatens equally-prized rural traditions extolling the values of family farming. To see in detail how strongly and in what ways large-scale farming is exerting its influence across the nation, a multivariate model was applied to county census data. Emphasized were forces of capital accumulation rather than traditional single criteria like farm size or incorporation. Results uniformly dispute the argument for continued vigor of the family farm. Smaller operators are not only disadvantaged in all production factors, but also are no longer protected by such traditional recourses as labor intensification and production efficiency. Far more farmers are also subjected to large-scale farming pressures well beyond the “factory farm” areas, and in several places to pressures as intense. One of these centers is the Western Corn Belt, a bastion of both technology and rural tradition, and thus quite possibly the place where the foremost dilemma in American agriculture is finally resolved.     

Trends and characteristics of part-time farming in post-war Japan

Part-time farming is a wide-spread phenomenon in contemporary rural Japan. Characterized by an extremely small-scale rice farming and by a unimodal equitable rural development, most Japanese farm households have combined farming with off-farm employment. In this article, after an examination of the definition of part-time farming (farm household as the unit), the trend of and factors for part-time farming are described and analyzed. Growth and expansion of off-farm employment opportunities, continued small-sized farming, rapid increase in farmland prices and development and diffusion of labor-saving technology are among the major forces which encouraged part-time farming in Japan. Although the overall performance of part-time farms appears less efficient in the use of non-labor resources (e.g., land and machinery), part-time farms still occupy a significant share in the aggregate agricultural production and in the total farmland cropped. Various on-farm and off-farm adjustments are pointed out which have enabled dual employment patterns to be adopted by these people. In essence, due to the limited opportunities for farm-size expansion, part-time farming is considered a necessity, rather than a choise, for most Japanese farm families. But this has also caused some serious agricultural problems, especially with respect to its impact on farmsize structure and inefficient land use. At least for the purpose of maintaining a high income level and for equitable access to opportunities, part-time farming has seemingly contributed beneficially to the farming population of Japan.     

Fair Trade and organic initiatives confronted with Bt cotton in Andhra Pradesh,India: A paradox

This paper explores a confluence of Fair Trade and organic initiatives under the prevalence of Bt cotton in India, using as an interpretative framework Guthman’s conventionalization thesis for organic farming in the Northern context. In a case study conducted in Andhra Pradesh, the confluence of the two initiatives, contrary to their ethical standards, contributed to the spread of genetically modified (GM) seed. The Fair Trade initiative, lacking a scheme for compensating for the decrease in income that producers have to endure during the conversion period, tends to take a more relaxed attitude toward GM crops in order to assist small farmers. Fair Trade’s dilemma between helping poor farmers and promoting organic farming may have indirectly allowed Fair Trade producers to tend towards conventional farming with Bt seeds. As a result, the confluence of the two initiatives has not intensified the organic concept as “an alternative accumulation strategy for agrarian capitalism,” but neither has it released disadvantaged Southern farmers from agrarian capitalism. Rather, it has led farmers into another form of agrarian capitalism.     

Part-time farming in Spain — a review

This paper is a review of statistical data and existing research on the part-time farming in Spain. The available data show an important level of development of the phenomenon: in 1965, 37.7 % of the earnings obtained by farm families are from jobs off the farm; in 1972, 48 % of the agrarian operators had main jobs off the farm. Most of the part-time farms are of small size although the phenomenon is also important on groups of farms of the largest size. The regional studies show a greater development of part-time farming in the Cantabrian coast, where the part-time farmer working in industry prevails, and in the E and S regions, where the jobs off the farm but within the agrarian sector (wage labour) are very important. Some studies on the stability of part-time farming show that this stability depends on the type of farming, the market of agricultural land in the area and the conditions of the jobs off the farm. In the present economic crisis the interest in part-time farming has been increased.Translated by Isabel Carbonell.

Actor and frontier types in the Brazilian Amazon: Assessing interactions and outcomes associated with frontier expansion

This paper analyzes frontier expansion in the Brazilian Amazon as a process that depends on multiple exogenous and endogenous factors operating at diverse scales, but whose trajectory depends on the dominant actor type (smallholders or medium- or large-scale landholders) occupying the frontier landscape. Despite the broad growing trend of pasture expansion for adoption of cattle ranching as the main land use associated with frontier expansion, some differences persist across actor types. In relative terms, medium- and large-scale landholders place most of their cleared forestland under pasture, and in absolute terms, largeholders have deforested more than smallholders because they hold larger tracts of land. Recently, however, deforestation activity has been increasing in frontiers occupied by smallholders who tend to convert a greater proportion of the forestland in their landholdings to agricultural land uses than larger-scale landholders, mainly to expand cattle ranching operations. Furthermore, smallholders tend to maintain higher cattle stocking rates than medium- and large-scale landholders, which tend to adopt extensive systems of cattle production. Both economic and human development indices in each frontier type vary according to actor type. While in absolute terms, higher per capita agricultural income levels are found in frontiers where largeholders predominate, the corresponding incomes are higher in smallholder frontiers when prorated by unit of land under crops and pasture. In addition, the Human Development Index is higher in frontiers with greater presence of large-scale landholdings.     

Are migrants exceptional resource degraders? A study of agricultural households in Ghana

Although some scholars describe migrant farmers as ‘exceptional resource degraders’ others do not. This paper uses evidence from the transitional agro-ecological zone of Ghana, to examine whether there are substantial differences between households of migrants and the host population regarding agricultural land use. The aim is to determine whether migrants are more destructive of the land (and hence the environment) than the host population. This will be examined using a standard model of the determinants of agricultural land use, to which we add variables representing demographic impacts, including in-migration. The data used are from a household survey undertaken in 2002 among 110 migrant and 142 host population farming households in central Ghana. Results are mixed. We find no support for the hypothesis that households with migrants are less likely to consider the long-term effects of land use by increasing the land area in cultivation, but at the same time there is evidence of use of more land-intensive agricultural practices which tend to degrade farm land over time.     

褶皱的地震波反射响应及其大陆地壳构造地质意义

褶皱是挤压造山带中最普遍的地质构造,但是为什么在地震反射剖面上却极少呈现褶皱呢?本文从一个构造地质学者的角度出发,数值模拟了几种常见褶皱构造的地震波反射响应。结果表明,传统的反射地震技术并不能正确成像闭合褶皱、斜歪或倒转褶皱及二级以上的多级复合褶皱。褶皱陡倾翼的反射消失,而褶皱转折端的反射形成一系列断断续续分布的假水平层理,这些假水平层理在下地壳中极易被错误地解释成由地壳拉张形成的水平构造层理或由底侵作用形成的水平基性岩席。笔者认为,老、中、新褶皱造山带的下地壳中大多数不连续水平反射可能是由褶皱造成的。     

Potential impact of ash eruptions on dairy farms from a study of the effects on a farm in eastern Bay of Plenty,New Zealand; implications for hazard mitigation

This paper investigates the impact ash fall would have on dairy farming, based on a study of ‘Tulachard’, a dairy farming operation at Rerewhakaaitu, North Island, New Zealand. It includes analysis of the potential effects on the dairy shed and milking machine, electrical supply and distribution, water supply and distribution, tractors and other farm vehicles, farm buildings (haysheds, pump sheds, implement sheds, etc.), milk-tanker access to the farm and critical needs of dairy cows and farm to keep milking. One of the most vulnerable areas identified in the study was the cooling of milk at the milking shed, pending dairy tanker pick-up. The cooling system’s condenser is exposed to the atmosphere and falling ash would make it highly vulnerable. Laboratory testing with wet and dry ash was conducted to determine its resilience to ash ingestion. It was found to perform satisfactorily during dry testing, but during wet testing significant clogging/blocking of the condenser’s radiator occurred, dramatically reducing airflow through the condenser. Specific mitigation recommendations have been developed that include cleaning with compressed air and adapting farm management techniques to lessen usage of the condenser during an ash-fall event. Specific recommendations for management of dairy farm operation are given to mitigate the effects of an ash-fall event.

The Hungarian diversification strategy: Constraints and opportunities

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.

Land use and land rights in the West African savannah: The Senufo in northern C^ote d'Ivoire

The change in property rights in the West African savannah has been analysed in particular from the perspective of development policy, i.e. from the perspective of state regulation. This contribution, however, attempts to trace property rights from the perspective of the farming population in the savannah in the northern part of Côte d'Ivoire. For peasants, the change of law is part of a long-term process which had already started before the colonialisation at the end of the 19th century and is still continuing today. The changing law is not analysed per se but is rather analysed with reference to people's actions, out of which the sphere of life of the local population is constituted. The changing forms of farm work and of land usage play an important role in this respect. The change of property rights is inscribed in the conflicts with the state and state power on the one hand, and the changes of social forms of organisation on the other.     

Urban influences on farming in Essex

The urban fringe is usually portrayed as a location of unrelieved adversity for farmers. It is rare for the costs of the urban fringe to be counterbalanced by an assessment of the opportunities that are also found there. This paper presents the results of a large scale farm survey in Essex which sought to examine the effects of urban proximity on farm management practices.The paper examines the nature and spatial extent of the following: conversion of farm land to urban uses (with special emphasis on the role of compulsory purchase orders); changes in farm labour; part time farming and the location of part time farmers jobs; vandalism and trespass damage and farmers response to this hazard; farm-based recreation and the sale of produce direct to the public. In general it is shown that the disadvantages of farming in the urban fringe have been overrated while the advantages have been underrated.     

Assessment of airborne bacteria and fungi in an indoor and outdoor environment

Airborne indoor and outdoor bacteria and fungi were assessed during the spring season using conventional methods to investigate the enumeration and identification of airborne micro-organisms. This was determined through air quality sampling using the ‘open plate technique’. The air samples were collected during the spring season (March-May) from four different locations. Conventional enumeration of airborne micro-organisms relies on culture-based or microscopic methods. Although a culture-based analysis is most widely used for bio-aerosol, four public places located in urban residential areas were selected for indoor/outdoor air bio-pollutant measurement. The public places included kitchens, classrooms, recreational areas, laboratories. Public parks are an important facility associated with the environmental exposure of children. Cultivation and total microscopic enumeration methods were employed for the sample analysis. 26 groups of bacteria and fungi, either of human or environmental origin were detected. Environmental agents generally predominated while significantly higher counts were detected as the level of hygiene or standard of housing dropped. Seven genera of fungi, mainly members of the genus Aspergillum, were isolated from all residents. Bacteria shows higher growth numbers as opposed to the slow growing fungi. Sample collection and pretreatment, determination techniques and performance results are summarized and discussed.     

任意角度水平向荷载下现浇X形桩力学特性研究（I）：惯性矩

现浇X形桩是为了提高单位混凝土承载力性能而开发的一种新型桩,异形横截面在确保桩周周长的前提下,能有效地减少混凝土用量;但目前针对异形横截面对水平向承载力特性影响方面的研究相对较少。基于X形横截面的3个控制参数：外包圆直径、开弧间距和开弧弧度,建立任意方向轴惯性矩控制方程,并分析X形横截面3个控制参数对截面轴惯性矩的影响规律。最后,提出控制截面面积或周长情况下X形截面惯性矩的最优化设计方案。研究结果表明,X形截面惯性矩随着开弧角度、开弧间距的减小而增大,随着外包圆直径的增大而增大。因此,在等混凝土材料用量或者控制桩周长情况下,适当增大外包圆直径、减小开弧角度和开弧间距有利于提高X形截面轴惯性矩,从而提高X形桩整体水平向承载力。     

Relationship between primary iron sulphide species,sulphur source,depth of formation and age of submarine exhalative sulphide deposits

Older and deeper-water submarine exhalative ore deposits tend to be pyrrhotite-bearing whereas pyrite is favoured in recent and shallow-water deposits. It is proposed that increases in sea water sulphur concentrations and Eh through geologic time and at shallower sea water depths, and also the tendency for solutions exhaled at greater water depths to be hotter may account for this observed relationship. Available sulphur isotope data for submarine exhalative deposits are compatible with this hypothesis. Many exceptions are noted to the commonly held view that pyrite breaks down to pyrrhotite at higher grades of metamorphism. Pyrrhotite bearing deposits tend to be older and formed in deep water tectonically active zones and are therefore more often metamorphosed. A loose correlation between metamorphism and pyrrhotite occurrence has thus resulted.
