The role of extension in fisheries development among rural communities

It is a common knowledge that there exists a wide gap between domestic fish production and demand in Nigeria. Government recognizes this situation and has in recent years encouraged fish production through fishing inputs subsidies, DFRRI assisted fingerlings production among others. Despite these efforts, impact at the grassroots has been low. One of the major reasons for the failure could be attributable to inadequate involvement of rural communities in fish production. This missing link appears to be ignorance of local communities in harnessing this potential to stimulate fish production. There is therefore the need to educate the rural dwellers through effective extension services. Strategies to achieve the required awareness have been discussed

Linking public perceptions of socioeconmic change and marine resource management in rural Maine

Rural coastal regions across the United States are coping with dramatic social and environmental changes. Historically, these areas relied heavily on fishing and marine commerce and these economic activities defined the character of coastal communities. However, shifting ocean and climate conditions, together with inadequate management strategies, have led to sharp declines in harvestable marine resources. These trends, along with increasing competition from aquaculture and international sources of fish, have led to the steady decline of fishing as the central economic activity in many rural coastal communities.

Impact of Nigerian Agricultural Cooperative and Rural Development Bank (NACRDB) loan to artisanal fishermen in Lake Kainji

This study was conducted to assess the impact of Nigerian Agricultural, Co-operative and Rural Development Bank Loan on beneficiaries and non-beneficiaries fishermen in Lake Kainji. A total of fifty fishermen (25 beneficiaries and 25 non-beneficiaries) were randomly selected from five fishing villages along the lake basin. Data collected were scored and the percentages of the parameters were calculated appropriately. The types of loans disbursed to beneficiaries revealed that 52% was cash and 48% was in kind. The credit package ranged between N5, 000 to N150, 000 only. Only 48% of the loans granted were paid while the rest remained unpaid. The results obtained from the membership of fishermen Cooperative showed that 64% of beneficiaries were members while 36% were non-members. Also 36% of non-beneficiaries were members while 64% were not. The Common fishing gears used by the two categories of fishermen include gillnets longline, castnet and driftnets. Sixty percent of beneficiaries and 8% of non-beneficiaries fishermen were using canoe with outboard engines while the rest used canoes with paddles. Beneficiaries earned a higher income (N1, 000 to N9, 000) daily than non-beneficiaries (N1, 000 to N6, 000) daily from sales of fish caught. Major contrainsts to increased catch and income identified include inadequate capital, non- availability of fishing inputs, stealing of fishing gears, lack of access to credit facilities and menace of stump and water hyacinth in the lake. Lastly, recommendation were made for the bank management, government and other lending institutions on how to improve the livelihood of the Artisanal fishermen by increasing the loan usually granted

Characterization of rural livelihood of Lake Chad basin fishermen

The study examined the characterization of rural livelihood of the fishermen in the Nigeria portion of Lake Chad Basin are as part of European Commission (EC) founded project entitled "Sustainable development of continental fisheries; a regional study of policy options and policy formation mechanisms for the Lake Chad Basin" Wealth ranking exercise which was not based on real income but on production capacity of the fishermen was carried out in twenty (20) villages survey on the western part of the region using Rapid Rural Appraisal Technique with semi- structured interviews. The different activities carried out by the villagers for living were identified according to their socio-economic status. This was followed by an assessment of the socio-economic characterization within each wealth group. Series of comparative analysis of the ethnic composition, accessibility of fishing gear ownership by the population were done. The results show that the 3 wealth groups in the region include the rich (Group 1) the middle class (Group 2) and the poor (Group 3). It was identified that fishing is just one component of the socio-economic production system along side farming, livestock rearing and trading which are closely integrated. The diversified livelihood system being practiced in the Chad Basin region are not only less vulnerable but also more sustainable

Poverty alleviation and rural development in Nigeria: a gender perspective

The paper examines the concept of the feminization of poverty and reviews the limited evidence on the extent of poverty among women. It then examines the arguments that poor women can be highly effective change agents for the eradication of poverty. However, all the women may be considered as instruments for eliminating poverty, lack of understanding an appreciation of the impact of their sex roles and of gender roles and stereotypes continue to prevent the realization of this potential. Therefore, the paper moves on to summarize the differences between sex and gender and examines how both women's sexes roles and the imp gender roles and stereotypes lead to the feminization of poverty and exclude women from the participation in development and programmes to eliminate poverty. The paper reviews the major approaches: women in development or WID, gender and development or GAD and extension of GAD known as mainstreaming. Finally, it considers the issue of poverty, women and gender in Nigeria. It also advances a number of recommendations on women and gender poverty and rural development for the consideration of policy-makers in Nigeria

Occupational practices and problems of rural artisanal fisherfolks in Oyan Dam area of Ogun State

Artisanal Fish Societies constitutes one of the poorest societies in the developing world. Attempts to harness the potentials of the societies have often failed due to the enormity of the problem of poverty. This study was conducted in four major fishing villages namely; Abule titun, Apojola, Imama Odo and Ibaro in order to investigate the occupational practices and the problems of rural artisanal fisherfolks in Oyam's Dam, area of Ogun State. Eighty respondents were randomly selected among the artisanal fisher folks for interview using interview guide. The findings revealed that 43.8% of the fisherfolks are within active range of 31-40 years while 30% are within 21-30 years range. Also 31% had no formal education indicating a relatively high level of illiteracy among the fisherfolks while majority of the respondents practice fishing activities using paddle and canoe. It was similarly discovered from the study that the most pressing problems of the fisherfolks is the lack of basic social amenities like electricity, potable water, access roads, hospitals and markets. It is therefore recommended that basic social infrastructures be provided for the artisanal fishing communities in order to improve their social welfare, standard of living and the capacity to have a sustainable fishing occupation in the interest of food security and poverty alleviation

Identification of thermally-tagged coherent structures in the zero pressure gradient turbulent boundary layer

A zero pressure gradient boundary layer over a flat plate is subjected to step changes in thermal condition at the wall, causing the formation of internal, heated layers. The resulting temperature fluctuations and their corresponding density variations are associated with turbulent coherent structures. Aero-optical distortion occurs when light passes through the boundary layer, encountering the changing index of refraction resulting from the density variations. Instantaneous measurements of streamwise velocity, temperature and the optical deflection angle experienced by a laser traversing the boundary layer are made using hot and cold wires and a Malley probe, respectively. Correlations of the deflection angle with the temperature and velocity records suggest that the dominant contribution to the deflection angle comes from thermally-tagged structures in the outer boundary layer with a convective velocity of approximately 0.8U∞. An examination of instantaneous temperature and velocity and their temporal gradients conditionally averaged around significant optical deflections shows behavior consistent with the passage of a heated vortex. Strong deflections are associated with strong negative temperature gradients, and strong positive velocity gradients where the sign of the streamwise velocity fluctuation changes. The power density spectrum of the optical deflections reveals associated structure size to be on the order of the boundary layer thickness. A comparison to the temperature and velocity spectra suggests that the responsible structures are smaller vortices in the outer boundary layer as opposed to larger scale motions. Notable differences between the power density spectra of the optical deflections and the temperature remain unresolved due to the low frequency response of the cold wire.

Bienestar subjetivo en el ámbito rural

El presente estudio se centra en el concepto de bienestar psicológico subjetivo, componente cualitativo de la calidad de vida y, por lo tanto, de especial relevancia en la intervención socioeducativa. El objetivo principal ha sido la valoración del bienestar subjetivo de la población en el medio rural. Se ha desarrollado en Matallana de Torio, un municipio de León de 1397 habitantes, participando en el mismo 318 personas adultas entre 18 y 86 años. Se analizó la literatura existente para valorar, por un lado, la importancia del concepto de bienestar subjetivo en relación con el de felicidad y con el de calidad de vida. Por otro lado, se exponen las concepciones sobre el medio rural para aproximarnos a una idea común acerca de este concepto tan cercano pero tan poco analizado desde este enfoque. Para llevar a cabo este análisis, se ha optado por una metodología cuantitativa, cuya naturaleza descriptiva, permite obtener resultados generalizables. Se han utilizado las escalas de Ryff, por constituir un instrumento de análisis del bienestar subjetivo contrastado y fiable. Los principales resultados derivados del análisis de datos indican niveles por debajo de la media en las dimensiones analizadas como: autoaceptación, relaciones positivas, autonomía, dominio del entorno, crecimiento personal y propósito en la vida. Este resultado puede estar relacionado con la variable cultural y las limitaciones derivadas de la escasez de servicios socioeducativos que se encuentran las personas en el ámbito rural.

Filamentation control in the temperature gradient argon gas

A novel technique of controlling the evolution of the filamentation was experimentally demonstrated in an argon gas-filled tube. The entrance of the filament was heated by a furnace and the other end was cooled with air, which resulted in the temperature gradient distribution along the tube. The experimental results show that multiple filaments are merged into a single filament and then no filament by only increasing the temperature at the entrance of the filament. Also, the filament can appear and disappear after increasing the local temperature and input pulse energy in turn. This technique offers another degree of freedom to control the filamentation and opens a new way for multi-mJ level monocycle pulse generation through filamentation in the noble gas.

Propriedade rural, posse e meio ambiente: uma ponderação harmoniosa

A presente tese tem por objetivo defender, sob a visão do direito civil-constitucional e da função promocional do direito, a inter-relação entre os direitos de posse, propriedade e do meio ambiente e a possibilidade de uma ponderação harmoniosa em caso de desequilíbrio entre esses direitos. Utiliza-se para tanto a dimensão analítica, empírica e normativa. A dimensão analítica tem por objetivo investigar os conceitos jurídicos envolvidos na pesquisa, especialmente em relação à propriedade e à sua função socioambiental. A relação entre tais conceitos sobressai através da análise da função socioambiental da propriedade, da posse enfatizando-se os aspectos da legislação ambiental. O direito fundamental ao meio ambiente é estudado como direito e dever de todos conforme disposto no art. 225 da Constituição de 1988, e, nesse ponto, diretamente eficaz nas relações interprivadas. Aborda-se, na dimensão empírica e normativa essencialmente aspectos práticos, com foco na jurisprudência, especialmente do Supremo Tribunal Federal (STF) e do Superior Tribunal de Justiça (STJ). A ponderação harmoniosa entre a propriedade, a posse e o meio ambiente, busca o equilíbrio na efetivação desses direitos, inclusive mediante a aplicação dos princípios do direito econômico. Por meio da ponderação, é possível alcançar, de forma mais eficiente do que o modelo tradicional de subsunção, uma resposta adequada e fundamentada para os casos difíceis, especialmente na efetivação e na restauração do equilíbrio entre a posse, a propriedade e o meio ambiente quando esses princípios, no caso concreto, colidem uns com os outros. Sobretudo, pretende-se concretizar os direitos fundamentais segundo exigências do pós-positivismo, por meio da aproximação entre o Direito e a Ética, com o fim de se alcançar a Justiça para o caso concreto.
