Farmers risk management behaviour determines the extent to which they overcome risk types. Information on crop farmers’ risk management behaviour in Nigeria is however scanty. Therefore determinants of agricultural risk management behaviour of crop farmers in Nigeria were investigated. Multistage sampling technique was used. Of the agro-ecological zones, Coastal, Rainforest and Guinea savannah were randomly selected. Thereafter, 10% of the states in the zones (Lagos, Osun and Niger) and 10% of the Local Governments Areas (LGAs) in the states were selected. Two communities were selected from each of the LGAs and 15% of crop farmers were chosen in the selected communities to give 323 crop farmers. Interview schedule was used to collect data on respondents’ risks types, risk exposure levels and risk management strategies. Indices were used to categorise farmers on their risk types (production, marketing, financial and social) and risk behaviour (superior, active, di-function, mono-function and part-time risk managers). Data were analysed using descriptive statistics, chi-square, Pearson Product Moment Correlation, ANOVA and multinomial logistic regression at p= 0.05. Most (90.0%) respondents were males, married (89.7%), and had at least primary school education (62.3%) with farm sizes of less than 5 hectares (72.3%). Age and years of farming experience were 53.2±10.5 and 28.3±12.1 years respectively. Majority (94.2%) identified inadequate cash-flow, pests and diseases (91.3%), ill-health of farmer/farm employee (89.0%) and volatility in output price (85.5%) as types of agricultural risks. Respondents were more vulnerable to production (9.85) and financial (9.84) risks. Majority (81.3%) were moderately or highly exposed to agricultural risks. Risk management strategies highly utilised were reducing leverage (2.94), maintaining good relations with contracting partners (2.73), use of fertilizers (2.65) and use of improved seedlings (2.57), while 73.9% of the farmers that had crop insurance coverage affirmed that it was effective in managing risks. Use of risk management strategies was low for 47.1%, with marketing strategies being the least (1.17) utilised. Superior agricultural risk managers accounted for 14.2%; active (26.8%); di-function (33.2%); mono-function (21.9%) and part-timers (3.9%), with the coastal zone having the highest percentage of superior (19.0%) and active (43.1%) risk managers. There were significant relationships between level of risk management and each of sex, marital status, educational level and farm size. While the Guinea savannah zone had the highest level (259.58) of agricultural risk exposure, the coastal zone had the highest level (75.89) of agricultural risk management. Significant predictors of agricultural risk management behaviour were farm size, organization membership and risk exposure level for mono-function and active managers. Di-function and superior managers were significantly predicted by farm size and risk exposure level respectively. Crop farmers in the zones encountered more of production and financial risks and lacked adequate risk management strategies. Their low level of insurance coverage indicated that factors other than awareness determined participation in insurance. Crop farmers should utilise more risk management strategies in order to reduce their risk exposure levels.

A.; Tijani, M. N.; Adekoya, A. E.; Tijani, S.A.; Adagbasa, E. G.; Aladejana, J. A. Abstract: The changing pattern of land cover is increasingly becoming of global concern in the sustainable management of environmental resources. Different facets of the natural ecosystem continue witnessing devastation orchestrated by rapid population growth and urban expansion in the face of climate change. This study examined the contribution of human’s to the global environmental change by assessing the dynamics of land cover between 1984 and 2017 while predicting the future extent of land cover pattern for 2047 at the Epe and Igbokoda areas on the coast of southwestern Nigeria. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM + ), and Operational Land Imager (OLI) imageries of 1984, 2002, and 2017 respectively were acquired from the USGS to analyse the land cover changes. Supervised classification was done using the maximum likelihood classifier of Terrset version 18.31. The Change Demand Modelling of Land Change Modeller (LCM) in Terrset integrates the Markov chain for future predictions for 2047. The Epe area which typifies a rapidly urbanizing coastal environment recorded an 84.6% increase in built-up area extent between 1984 and 2017, while the built-up area of the Igbokoda area increased by 103.8% for the same period. This increment corresponds to a decrease in the spatial extent of the forested wetlands with an increase in water bodies. Expansion of water body extents indicates the interaction between the elements of climate change such as incessant flooding and anthropogenic activities like deforestation, urban expansion through sand mining and dredging. Future prediction into 2047 connotes further worsening of the situation. Therefore, solution-based sustainable coastal management practices are recommended to salvage the impoverishing coastal ecosystems from further impairment.

M.; Tijani, S. A.; Oguntade, M. I. Abstract: The study assessed determinants of farmers’ utilisation of University of Ibadan (UI) Agricultural Research Outputs (AROs) in Oyo and Osun States, Nigeria. A multi-stage sampling procedure was used to select 176 beneficiaries of AROs in the study area. Focus Group Discussion and interview schedule were used for data collection on respondents’ socio-economic characteristics, knowledge, utilisation level and determinants of utilisation of UI AROs. Data was analysed using descriptive and inferential statistics like Chi square, PPMC, and multiple regression. AROs considered for the study were use of neem (Azadirachta indica) extract for pest management, rice-fish-poultry integrated farming system, processing of moringa oleifera powder and ruminant feed block meal pattern. Results reveal that respondents’ mean age household size were 40.05±35.48 years of 4.04±1.25 persons respectively. Respondents had mean farming experience of 7.92±5.26 years. The most utilised source of labour was family (63.0%) with mean farm size of 1.56±0.93 acres. Respondents’ knowledge (67.0%), and utilisation (55.7%) of UI AROs were high for innovations disseminated. Respondents’ marital status (χ2=5.99), sex (χ2=3.92), level of education (χ2=30.69); age (r=0.23) and income (r=0.79) were significantly related to UI AROs utilisation. Respondents’ knowledge (r=0.32) and benefits derived (r=0.80) were significantly related to utilisation of UI AROs. The determinants of utilisation of the AROs included educational qualification (β = 0.462), years of farming or processing experience (β=0.27), scale of production (β=0.33) and knowledge on utilisation (β=0.45). The study recommends that farmers be encouraged to improve on their level of education for better utilisation of disseminated agricultural research outputs.

A. Abstract: Vegetable production had been a major source of livelihood among women in Guinea. This study therefore, assessed the determinants of vegetable women farmers’ economic security in the Boke region of Guinea. A multi-stage sampling procedure was used to select 180 respondents for the study. Data was elicited from the respondents with the aid of interview schedule and analysed using descriptive and inferential statistics. The results revealed that average household and farm size cultivated respectively were 8.54±3.55 persons and 1.17±0.62 ha. Personal land (71.7%), household (97.2%) and hired labourers (84.4%) were used by respondents. Almost all (95.0%) relied on personal savings for the finance of vegetable farming. Prominent constraints against vegetable production were inability to access credit at banks (x̅=1.87), lack of storage (x̅=1.87) and processing (x̅=1.86) facility. Vegetable enterprise was not profitable for 53.3% of respondents. Income from vegetable farming was neither adequate (99.4%) nor stable (100.0%). Average annual expenditure ($4,664.92±1723.75) was higher than annual income ($704.49±1,379.98) Almost all the respondents were economically insecure (98.9%) thus unsustainable livelihood and inability to cope with emergencies. Significant predictors of economic security among respondents were household size(β=-0.229), use of personal land (β=-0.188), use of rented or lease land (β=-0.205), use of family land (β=-0.142), use of family/ hired labour (β=0.159), annual income (vegetable) (β=0.596) and the number of vegetables grown (β =-0.150). The study recommends that farmers be encouraged to form cooperatives in order to facilitate access to credit facilities, need for the establishment of cottage industries and promotion of value addition.
