Guinea fowl production offers an income source that could reduce the incidence of poverty of rural householders in Northern Ghana, considered one of the poorest regions in West Africa, due to its unimodal rainfall patterns that restrict the year-round production of crops. However, information on profitability and resource use in guinea fowl production in Northern Ghana is very limited. We assessed the resource-use efficiency of guinea fowl production in the Savelugu-Nanton district of the Northern Region of Ghana based on a random-sampling survey of 192 guinea fowl producers using data for the 2018 production year. The study revealed that the average flock size per producer was 82 birds; the average gross margin was about 1,499 Ghana cedis (GHS), and the average return on investment was 16.7%. High mortality rates of birds and frequent incidences of diseases were the most important challenges faced by the producers. We recommend that the government improves its extension services to farmers, especially in veterinary care services for detection and early treatment of diseases. Key words: Guinea fowl, human capital, Ghana, poultry production, resource efficiency, risk aversion.

Family farms are poorly modernized in Burkina Faso despite their predominance in the country’s agriculture and their major contribution to national food production. Convincing evidence of the contribution of family farm modernization to food security is needed to support advocacy. This study used data from recent national longitudinal surveys and Cox semi-parametric regression methods to explore the effect of factors of modernization on the food security of farm households in Burkina Faso. The results showed that the training of agricultural workers, ownership of traction animals, and use of improved seeds reduced the risk of food-secure households falling into food insecurity by 22.8, 21.6, and 14.9%, respectively. These three factors significantly determine the stability of households’ food security, suggesting that the modernization of family farms could contribute to the prevention of food insecurity in Burkina Faso. A key strength of this study is that it was able to capitalize on the wealth of these data, which come from national surveys that are representative of farm households at the provincial level, longitudinal and prospective, making it possible to track the same households over time, at an annual frequency. Key words: Agricultural modernization, family farming, food security, Burkina Faso

To assess the win-win of both China and Zimbabwe if Zimbabwe diversifies its agricultural exports into the Chinese market, this study employs a Computable General Equilibrium (CGE) model that is becoming popular in analyzing economic issues. With Zimbabwe having been in a constant financial and economic crisis and the major sector not contributing much to the economic growth, a bilateral Free Trade Agreement on Agriculture and Agri-based commodities between China and Zimbabwe was proposed based on the Forum for China-Africa Cooperation Action Plan (2019-2021). To evaluate the policy change, the study used a CGE and Dynamic Global Trade Analysis Project (GTAP) model 2011 and employed two policy scenarios of baseline and that of zero tariffs. By comparing the baseline and policy simulation results for the periods (2020-2030), the research found that the policy would be a win-win to both countries but with more negative impacts on Zimbabwe. The study therefore proposed some recommendations aimed at sustaining the policy change should the two countries engage in it. The recommendations included the need for agricultural research and development to boost agricultural production and exports in Zimbabwe. Key words: Computable general equilibrium dynamic model, global trade analysis project, bilateral free trade agreement, Zimbabwe, China.

Undertaking non-agrarian income-generating activities to reduce overreliance on agriculture, production failures, and income fluctuations is a household-amenable, self-insurance mechanism, which provides employment opportunities and capital investment. This article examines the determinants of participation in non-farm activities and effect on household income. Heckman two-step procedure was used to analyze a three-wave survey data set captured from 3866 households. Crop failures, insufficient intake of food, household consumption expenditure, gender, family size, literacy, health status, farm animals holding, access to credit, total hired labor, cooperative membership and agricultural extension services were factors influencing household involvement in non-farm work. Furthermore, the findings establish that there is a decline in the likelihood of households headed by aged people, who tend to rely on subsistence farming to engage in alternative non-agrarian activities. The results of the analyses support the non-separability hypothesis of non-farm activities and household income; this implies that engaging in non-agricultural activities has a direct positive effect on household income. The omnipresence of non-agrarian income generating activities in agro-ecoregions requires inclusive rural development policies that focus beyond agriculture based on the recognition of the rural economic heterogeneity. Key words: Rural development, non-farm activities, household income, Heckman Two-Step model, Ethiopia.

Despite claims that Taenia saginata taeniosis/cysticercosis cause adverse financial and socioeconomic effects on cattle farmers, there is no recent empirical evidence to justify this assertion in Botswana. This paper provides empirical analysis of bovine taeniosis and cysticercosis effects on farmers’ wellbeing in Botswana. Interviews and observations using non-participatory structured questionnaire were used to collect primary data from industry stakeholders ( =149). Socio-economic effects were determined by analyzing fourteen (14) objectively verifiable socioeconomic indicators (OVIs) using binomial regression, while financial losses were estimated using means. Results indicate that farmers’ emotional wellbeing and ability to save money were significantly affected (p<0.05) and ability to provide food for family was significantly affected (p<0.10). Affected farmers were 30.30 times (SE=0.87), 11.02 times (SE=0.89) and 8.29 times more likely to experience emotional disturbance, unable to save money and unable to provide food for family, respectively, compared to unaffected farmers. Economic losses arise from condemnation and devaluation of carcasses. Farmers’ response to bovine cysticercosis effect included, diversifying, downsizing or abandoning cattle farming. Currently, Botswana government does not compensate for condemned carcasses but this study recommends compensation and provision of re-stocking seed calves as most efficient government intervention measure. Also, cattle insurance is recommended to reduce loss and disease cost. Key words: Taenia saginata cysticercosis, cattle farming, financial loses, socio-economic effects.

Python meat is a traditional but small source of protein throughout much of sub-Saharan Africa, but supply is exclusively from wild harvest. We build on recent evidence that supports snake farming as a viable and sustainable small-scale livestock system in Asia. We explore python farming as a strategy for enhanced food security in Zimbabwe. Our survey results highlight challenges, including drought and human-wildlife conflicts that face both traditional free-range livestock systems and food security, and reveal production prerequisites for complementary python farming. Preliminary findings suggest small-scale python farming could present a viable and sustainable complement to increasingly vulnerable traditional livestock systems. Key words: Adaptation, sustainable agriculture, python farming.

Nairobi National Park is a protected ecosystem where various types of wildlife find hiding place. The park has in the recent past experienced destruction through construction of a standard gauge railway (SGR) line and a highway called the Southern bypass. These developments raise concern with the possibility that their combined environmental cost being enormous. This study sought to determine the willingness to pay (WTP) for the restoration of the park attributes using discrete choice experiment. The focus was on the attributes of (1) wildlife population and diversity of species, (2) wildlife movement in dispersion and migration areas, (3) vegetation density and diversity, (4) security of wildlife and people, and (5) environmental safety and quality. The data used was collected from 93 students of Kisii University, Nairobi campus. A price attribute in form of an increase in gate fee was included to elicit WTP estimates. Multinomial logit regression estimates indicated that respondents were WTP for the restoration of all the attributes except attribute 4. Attributes 1 and 2 elicited the highest WTP and could be the most affected by the two projects. Middle-aged respondents with stable jobs were likely to pay more for the restoration of the attributes compared to students and the youth. Based on the findings, the government could consider relocating the park to a place with better environmental attributes. Key words: Nairobi National Park, ecosystem, discrete choice experiment, willingness to pay, park attributes, Multinomial logit.

The investigation considered farmers’ readiness to take part in crop insurance in the Dormaa municipality of the Bono Region, Ghana. Essential information from 167 respondents who were chosen through a multi-stage sampling method for the study was collected through a structured questionnaire. Elements influencing readiness to participate in crop protection by cocoa farmers was evaluated using probit regression model and lastly constraints of cocoa farmers were assessed utilizing Kendall’s coefficient of concordance. The study found that the average amount farmers were eager to pay was GH₵215.59 per year for crop insurance. Majority 96.7% of the respondents were eager to participate in crop insurance but 3.3% of the respondents were not willing to take part. The important factors influencing readiness to join crop insurance by the farmers were age, marital status, access to extension service and experience in cocoa farming. Again, the foremost constraint affecting the farmers was pests and diseases. The study therefore recommends that agricultural extension agents and other agricultural insurance stakeholders should sensitize crop farmers on the significance of crop insurance policy. Insurance companies ought to give crop insurance to farmers at moderate rates of GH¢ 215.59 per year to encourage their participation. Key words: Crop insurance, cocoa, probit regression, Dormaa Municipal assembly, Ghana.

Production of orange-fleshed sweet potato (OFSP) in Tanzania is constrained by the underutilization of virus-free improved certified planting materials. The sustainable use of these planting materials leads to the constant demand of the planting materials by farmers which can be triggered from viable processing. We determine the viability of processing in the OFSP value chain and its contribution to the uptake of high-quality improved planting materials. Data for this study were collected by field survey method from 15 processors and 150 farmers. Purposive and three-stage random sampling methods were used in sampling. We adopted a mixed method of analysis using descriptive statistics, gross margin analysis, and econometric estimation of the multivariate probit model by means of a Simulated Maximum Likelihood (SML). We found no direct effect of processing to trigger the use of improved OFSP planting materials unless formalization of the supply arrangements between processors and farmers is institutionalized. However, it was economically viable to engage in the processing of OFSP. Processors were found to be generating a benefit of US$ 76/ton of OFSP processed with a margin to a total cost ratio of 19% implying a relatively low margin with significant processing costs. Seed renewal was low as 63.1% of the farmers used retained planting materials. Nevertheless, contractual arrangements with the processors increased the desire to use high-quality improved planting materials and the likelihood to source them from research institutes (p<0.05). Additionally, access to credit and a high level of specialization influenced farmers to source planting materials from local vine multipliers. Creation of market linkage and formalization of supply arrangements between processors and farmers and awareness creation on the economic benefits of seed renewal will increase the benefits generated by processors. This may contribute to the uptake of high-quality improved OFSP planting materials in Tanzania. Key words: Economic viability, orange fleshed sweet potato, processing, value chain, market linkage.

Soil degradation, one of the causes associated with declining maize productivity is an environmental concern whose consequences are felt most strongly by poor people in developing countries. Indeed, the production of maize on soil fertilized with a combination of mycorrhizal fungi and half a dose of NPK has resulted in a production like that of the extension practice in Benin. This study aims, through an analysis of the financial profitability, to highlight the interest that maize production can generate with the production system using biofertilizer based on arbuscular mycorrhizal fungi (AMF) in Benin. The study was conducted among 100 randomly selected maize producers in 9 villages in South-Benin, Central-Benin and North-Benin. Economic profitability indicators including net margin, average labor productivity, and profit-cost ratio were determined. The results showed that regardless of the production area, maize cultivation with the AMF biofertilizer-based system was more profitable for producers (63,830 FCAF of net margin against 43,730 FCAF for vulgarized practice). Thus, agricultural policies could be oriented towards the promotion of maize inputs based on AMF bio-fertilizers to facilitate their availability to producers. Key words: Arbuscular mycorrhizal, Zea mays L., crop production systems; economic efficiency, farm development, Benin.
