Background: Oil exploration operations decreased the cultivable lands of rural people in the study area, leading to the establishment of the Green River Project (GRP). This study assessed the effectiveness and constraints of private sector extension services of GRP in Imo and Rivers States, Nigeria. Objectives: To analyse the roles and effectiveness of, as well as constraints to, the GRP in the area. Method: A multistage sampling technique was used to select 120 respondents. Descriptive statistics, factor analysis, chi square and t-test were used to analyse the data. Results: Roles of GRP in farming technologies dissemination included training of farmers on fish pond construction technique and maintenance of good pH levels. There was significant improvement in standard of living (X2 = 15.7; p ≤ 0.05) and size of production (t = 6.398; p ≤ 0.05) of the respondents after participation. In terms of the effectiveness of private sector deliveries on public policies, the programme had effect on beneficiaries’ access to credit, education of wards and poverty reduction. But it is worthy to note that the observed changes may not have been solely caused by the GRP, given that there could be many other factors affecting fish farming, either positively or negatively. Serious implementation constraints to effective performance of GRP included organisational, input and sustainability constraints. Conclusion: It was recommended that there should be timely provision of sufficient inputs to farmers and measures to improve organisation of private sector extension services in the area in order to enhance development.

Climate change affects agriculture in many ways, one of which is its direct impact on food production. This is particularly significant in developing countries, where agriculture is mainly rain-fed, providing employment and income for the majority of the population. This paper, based on data from 400 randomly selected farmers in Enugu and Imo states in South East Nigeria, assesses some effects of climate change and the cost implications of farmers' adaptation practices. Virtually all respondents reported unusual rises in extreme events such as thunderstorms, heavy winds and intense heatwaves; uncertainties at the start of the farming season such as unusual early rains, erratic rainfall and delay in the onset of rain; the incidence of pests, diseases and weeds; and signs of land degradation such as declining soil fertility and the drying up of streams or rivers. The overall impact (on farm yield and income) was significantly higher for Enugu than for Imo, possibly because Enugu has drier weather. The greatest perceived effects of climate change were reduced yield and income, drying up of streams and rivers, reduced storage quality of crops, loss of pastureland and/or vegetation and the destruction of wildlife ecosystems. Coping strategies with a relatively high profitability index were multiple cropping/intercropping, agro-forestry/afforestation, mulching, purchase/ harvesting of water for irrigation and the use of resistant varieties. Extension services need to promote appropriate adaptation practices among farmers.

This study described the structure, conduct and performance of banana market in Anambra State of Nigeria. The specific objectives are to describe the structure of the banana market; analyze the conduct of the banana market; determine banana market performance; and examine the major problems of banana marketing in the area. One hundred and twenty respondents spread in six major urban centers in the State and their concomitant major markets were randomly selected for interview. Descriptive statistics, Gini coefficient measure and the price spread analysis were used to analyse data. The study revealed that the activities of the banana market structure is almost optimum with a good conduct and performance as farmer's share of the consumer spending is 56%. The study also shows that lack of storage facilities and capital were the most pressing problems of the middlemen while the farmers were constrained from increased production by lack of capital, high yielding and disease resistant banana varieties. Policy recommendation to this effect was suggested.

Women constitute great apostles in agricultural production, processing, utilization and marketing as well as national economic growth. Given the increasing demands for basic crop products such as garri and milled rice in the diets of most households in Enugu south area, Nigeria, the marketing situation seems to be low relative to distribution. In this regard, this study investigated women marketers' perceived constraints on marketing of milled rice and garri in Enugu south area and highlighted challenges of extension training for women groups in Enugu State, Nigeria. One hundred and sixty randomly selected women marketers in Enugu South area constituted the sample size for the study. Structured interview schedule was employed in data collection.Frequency counts, percentage and factor analysis technique were the analytical tools adopted. The findings revealed that majority (63.8%) of the women were within the ages of 31-50 years, while majority (75.5%) have 6-20 years of marketing experience and 69.4 % of them have equity capital of N5,001.00-N45,000.00. The major constraints perceived by the women included inadequate processing skill, produce deterioration and lack of storage facilities. The study highlighted challenges for extension training in women groups on improved government budgetary allocation to ADP, organizational overhaul and re-orientation in the ADP and women group mobilization with focus on groups for extension training and contact. In conclusion, success in agricultural produce marketing in Enugu South area and associated marketing extension training for women groups in Enugu State, Nigeria depend on the extent constraint issues raised and challenges thereof highlighted can be addressed.
