An inventory of NGOs working in the region was established, and 11 out of 25 were found to be active in agricultural development. These 11 NGOs were visited and interviewed. They employ 39 trained extension officers, are able to reach 196 farmer groups or 5320 farmers. They typically work with farmer groups and use participatory methods, but also work in\u0000other fields, in particular health, water, and micro-enterprise development. The NGO staff is well motivated and enjoys good working conditions and operational budgets. However, they have little technical training, their number is small compared to the 572 extension officers of the MoARD, and they reach only a fraction of the estimated 370,000 rural households. Therefore, NGOs cannot be expected to take over any of the\u0000major tasks of the conventional agricultural extension services, but should be included in a larger collaboration between agricultural research, the extension services of the MoARD, and non-traditional partners. To this collaboration NGOs would bring their enthusiasm, proficiency in participatory methods, and close contact with the population; agricultural extension services would bring their technical knowledge and experience; and agricultural research would bring the new technologies to be adapted and tested.

Poor urban households spend 90% of their meager monthly income on food. Urban agriculture being an individual household micro level strategy directly influences the financial empowerment of urban poor positively. However, the benefit of urban farming is hinged on availability of productive land and water resources for this economic group. In Lagos, the land ownership system makes it rather cumbersome for poor urban farmers to access land. This paper examines potential land and water resources that could accommodate\u0000urban agriculture in the metropolis. The study identified 1,197 and 28,890 hectares of potential land resources under the jurisdiction of Federal, State and private ownership respectively. The use of such land resources requires the comprehension of long term primary land use goals and objectives. Such aims will influence the choice of crops and ideal number of farmers for land and economic resources sustainability.

This paper quantifies the contribution of fuel wood as a non-timber forest product (NTFP) to income and food security of the households surrounding the Dzalanyama Forest Reserve. A sample of 150 migrant exotic fuel wood collectors, migrant indigenous wood collectors and\u0000charcoal burners within 25 km radius of Dzalanyama Forest Reserve, were randomly selected using twostage cluster sampling method and probability proportion to size (PPS). The results showed that most women sold head-loads as collected and none traveled to town to sell fuel wood. It is clear from the results that the collectors who sold wood to town earned more revenue than collectors who sold wood within the village. The results further show that mode of transport affected the amount of revenue earned from fuel\u0000wood sales, with bicycle being more remunerative than head loads. Women used head load and rarely accessed urban markets, which explain their lower earnings than men. Consequently, men's earnings contributed 12% to food security compared with only 5% for women. Thus, although minimal, the incomes realized assisted communities surrounding Dzalanyama Forest Reserve to reduce the impact of shocks and stress of low yields and crop failure. To ensure economic and ecological sustainability of the Forest\u0000Reserve, there is a need for participatory management planning, involving all stakeholders.

This study focused on transaction costs that cotton farmers incur. The study therefore aimed at determining transaction costs that cotton farmers incur in production and other factors that effect farmers' demand for seed and pesticides, and estimating the proportion of total variable costs of cotton production accounted for by transaction costs. A survey of\u0000cotton farmers was conducted in Kumi and Pallisa districts, well known for cotton production in eastern Uganda The econometric models used in this study stem from the theory of log linear or constant elasticity form of single demand equations. Linear regression analysis of data was executed using SPSS in order to facilitate the estimation of the demand functions for cotton seed and pesticides. Results indicate that the percentage share of transaction costs of total variable costs of production was remarkable (34 %). A break down of total transaction costs revealed that lost revenue formed the greatest percentage (85%),\u0000followed by imputed transport costs (11%) and opportunity cost of travel and waiting time (4%), respectively. However, the statistically significant determinants of farmers' demand for cotton seed and pesticides were farmers' income and size of the cotton field. To enable the smallholder farmers who usually plant small areas to cotton, and the low-income farmers who are the majority in the rural areas, policy amendments inclined towards reduction of the transaction costs can improve the profitability of the cotton enterprise by\u0000increasing the demand for inputs. Stakeholders in the cotton sub sector responsible for seed distribution should also delivery the seed in time.

This paper examines the influence of farmers' socioeconomic characteristics and land management practices on the profitability of rice-based production systems in Osun State of Nigeria. A two stage sampling technique was employed to collect data from two hundred and fifty farmers using a structured questionnaire with the assistance of village extension agents. Primary data on demographic,\u0000socioeconomic characteristics, as well as constraints to rice production were collected while secondary data were obtained from the publications of CBN, FOS, Ministry of Agriculture and the Local Government Area secretariats. Data were analysed with descriptive statistics, budgetary and multiple regression techniques. Results showed that rice farming is on a small scale with a mean of 1.39 hectares in the study area. Land management practices such as inorganic fertilizer, bush fallow, shifting cultivation, crop rotation and crop rotation/inorganic fertilizer mix were identified. Inorganic fertilizer was most predominant\u0000as claimed by 73% of the respondents. Crop rotation/inorganic fertilizer recorded the highest net returns of N61,272.86 per hectare over variable costs while labour constituted a major cost component on rice farms. Age, level of education, labour and farm size significantly influenced the net returns to rice farmers. Rice-based production systems will contribute to food security and poverty reduction if more effective extension services are employed to train farmers on appropriate use of land management and other\u0000information from research findings.

The market structure was found to be oligopsonistic in nature with aspects of collusion amongst the urban middlemen and local market traders thus barring further entry by other potential actors. There was little market integration between urban markets and producing markets, and very low or no integration between the remote producing markets. Market information flow between\u0000production and consumption markets influence integration. Highly integrated horticultural markets are likely to increase market efficiency through efficient resource allocation and price transmission which would result in lower transaction costs and increased incomes and profits to market actors. Improved marketing efficiency for fresh pineapple calls for improving integration process of the markets. We recommend deliberate efforts to promote market integration as a strategy for improving rural incomes since more incomes and profits would encourage more market actors to enter the marketing agribusiness system.

MFIs have developed ways of reducing these transaction costs and risks through group lending and solidarity guarantee, among others. Those that will become licensed by the central bank will take deposits and on-lend if need be under the MDI ACT 2003. This is an important step towards financial savings mobilization that has been neglected in the past. However, this calls for better governance and efficiency in running the MFIs if they are to be self-sustainable and improve on their outreach. As more MFIs get registered and regulated by the central bank, they will invariably in the long-run have to shift to higher degrees of financial self-sufficiency and outreach. \u0000The objectives of this study was to determine the level of self-sustainability using Subsidy Dependence Index /Ratio and depth of outreach for a representative microfinance institution in Uganda, Teso Rural Development Trust Ltd (TERUDET). The study was conducted in districts of Soroti, Katakwi and Kaberamaido. Primary data were collected from 180 randomly selected active clients of TERUDET and secondary data were obtained from audited and un-audited financial statements of TERUDET for the period 1998-2003. The results show that TERUDET was heavily dependent on external funds. It was not profitable and self-sustainable through its own income in the period 1998-2003. Its depth of outreach was also low in that it covered more of the non-poor people than the poor. Key words: financial self-sustainability, microfinance institutions, outreach performance.
