Health education impact on knowledge and management of arboviral diseases in Kenya: Evidence from randomised control trials.

Communities' knowledge and management strategies are crucial for mitigating and controlling the threat of existing and emerging diseases. In this study, we conducted randomised control trials (RCT) to examine the impact of health education on households' knowledge and management of three Arboviral Diseases (ADs); Rift Valley fever, Chikungunya fever, and Dengue fever in Kenya. The study was based on a sample of 629 households drawn from the three of Kenya's AD hotspot counties; Baringo, Kwale, and Kilifi. Employing a difference-in-difference method, our findings indicate that health education intervention significantly improved households' understanding of ADs transmission modes, causes, and prevention strategies. However, this intervention did not sufficiently influence households' disease management behaviour. We recommend the implementation of community engagement and outreach initiatives which have the potential to drive behavioural changes at the household level, thus enhancing the management and control of ADs in Kenya.

Intensity of adoption of integrated pest management practices in Rwanda: A fractional logit approach.

The push-pull technology (PPT) is considered as an alternative integrated pest management strategy for the control of fall armyworm and stemborer, among smallholder maize farmers in sub-Sahara African to conventional pesticides. However, the extent of PPT use in Rwanda where the technology was introduced in 2017 remains largely unexplored. This paper employed a fractional logit model to assess the factors influencing the intensity of adoption of PPT among smallholder maize farmers in Gatsibo and Nyagatare districts of Rwanda using survey data obtained from 194 PPT adopter households selected using a cluster sampling technique. While only 5 percent of smallholder farmers in Rwanda have adopted PPT as an integrated pest management strategy, on the average, these farmers cultivated 26 percent of their maize plots to the technology. Our results show that the perceived benefits of PPT, its perceived effectiveness in pest control, group membership, livestock ownership, and gender of the farmer had significant effects on the intensity of adoption of the PPT in Rwanda. These findings give compelling evidence to recommend that development initiatives should give emphasis on creating awareness on the perceived benefits of PPT adoption using group approaches that are gender disaggregated.

Effect of farmer socio-economic characteristics on extension services demand and its intensity of use in post-conflict Liberia.

Farmers' demand for and use of agricultural extension services in post-conflict countries is key not only to agricultural productivity but for economic transformation and maintenance of peace. This paper examined the effect of socio-economic characteristics of smallholder rice farmers on demand for extension services and the intensity of their use in Gibi District of Liberia. Multistage sampling technique was used in select 296 smallholder rice farmers. Descriptive statistics were used to compare farmers' socio-economic characteristics and the heckpoisson model was used to simultaneously estimate the effect of socio-economic characteristics on demand for extension services and the intensity of their use. The results showed that farm income, sale of crops and mobile phone ownership had significant effect on farmers' demand for extension services, while gender, cash-crop ownership, use of improved seeds, and awareness of extension services had significant effects on the intensity of their use. The study suggests that government implements programs that promote increased provision of needed farm inputs for greater use of extension services and encourages commercialization among farmers. Also, service providers should tailor their services to the farmers' socio-economic characteristics.

Assessment of factors affecting the decision of smallholder farmers to use alternative maize storage technologies in Gatsibo District-Rwanda.

Storage is an important aspect of food security in developing countries. Therefore, it is crucial for farmers to have access to sustainable storage technologies to cope with storage losses. Maize is an important staple and commercial food in Rwanda, but maize farmers are still being challenged by storage losses because of the lack of proper storage facilities. It is in that regard that advanced maize storage technology, notably hermetic maize storage technology, has been introduced in Rwanda in 2012. However, since its introduction, the adoption rate is low among smallholder maize farmers. Understanding the factors influencing farmers' choice of alternative maize storage technology could provide Rwandan policymakers with important information for designing policies and programs aimed at reducing maize post-harvest losses to enhance household food security. This study used a multivariate probit model on a randomly selected cross-sectional sample of 301 smallholder maize farmers from the Gatsibo District of Rwanda to take part. The results revealed that the common maize storage technologies used among smallholder farmers were polypropylene sacks with and without chemicals, hermetic bags, and silos. Only 41% of respondents used hermetic maize storage technology. The model results showed that membership in a farmer group, access to credit, the quantity of maize produced, access to training, and selling maize soon after it dries, were the major factors influencing the decision of smallholder farmers to use alternative maize storage technologies. The study recommends that the policymakers and other stakeholders in post-harvest loss reduction should support the dissemination of advanced storage technologies to facilitate access. The government should support farmer acquisition of post-harvest maize loss reduction technologies either through subsidization of hermetic bags or provision of cheap credit.

Evaluating livestock farmers knowledge, beliefs, and management of arboviral diseases in Kenya: A multivariate fractional probit approach.

Globally, arthropod-borne virus (arbovirus) infections continue to pose substantial threats to public health and economic development, especially in developing countries. In Kenya, although arboviral diseases (ADs) are largely endemic, little is known about the factors influencing livestock farmers' knowledge, beliefs, and management (KBM) of the three major ADs: Rift Valley fever (RVF), dengue fever and chikungunya fever. This study evaluates the drivers of livestock farmers' KBM of ADs from a sample of 629 respondents selected using a three-stage sampling procedure in Kenya's three hotspot counties of Baringo, Kwale, and Kilifi. A multivariate fractional probit model was used to assess the factors influencing the intensity of KBM. Only a quarter of the farmers had any knowledge of ADs while over four-fifths of them could not manage any of the three diseases. Access to information (experience and awareness), income, education, religion, and distance to a health facility considerably influenced the intensity of farmers' KBM of ADs in Kenya. Thus, initiatives geared towards improving access to information through massive awareness campaigns are necessary to mitigate behavioral barriers in ADs management among rural communities in Kenya.

What is the impact of rural bank credit access on the technical efficiency of smallholder cassava farmers in Ghana? An endogenous switching regression analysis.

This paper assesses the impact of access to credit from rural and community banks (RCBs) on the technical efficiency of smallholder cassava farmers in Ghana. The study employed the stochastic frontier, and endogenous switching regression models to estimate the technical efficiency, and the impact of RCB credit access, respectively, on a randomly selected sample of 300 smallholder cassava farmers in the Fanteakwa District of Ghana. Results suggest that cassava farmers in the District are 70.5 percent technically efficient implying that cassava yield levels could be increased further by 29.5 percent without changing the current levels of inputs. The results further reveal that the gender of the household head, access to extension services, membership in farmer organizations, and proximity to the bank are the major factors that positively influence farmers to access credit from RCBs. On average, farmers who accessed credit from RCBs have significantly higher technical efficiencies than farmers who did not access, suggesting that access to credit from RCBs positively impacts the technical efficiency of smallholder cassava farmers.

What factors influence access to and the level of participation in high value mango markets by smallholder farmers in Ghana?

Market participation is critical to smallholder agricultural production because it stimulates increased productivity and enhances poverty alleviation. Accessibility to high value markets and participation by small-scale mango farmers in these markets in Southern Ghana are low and have received little attention on both policy and academic fronts. This study analyzed the factors that drive smallholder farmers in Ghana to participate in high value mango markets in Southern Ghana. A multistage random sampling technique was used to select 224 mango-producing households. A triple hurdle model was used in the study to capture a 3-step decision-making process. The results from the estimation of the triple hurdle model showed that participation in high value markets was influenced by education, household income, farming experience, ownership of a motorized transport (tricycle) and a radio, trust, distance to road, certification and access to credit. The level of participation in the export markets was determined by household size, household income, farming experience, distance to tarmacked roads and price. The study recommends intensive education and training to capacitate smallholder farmers to enable them to understand and meet the requirements of high value markets. Also, the farmers should be given access to credit and transaction-costs-reducing assets to enhance their participation in high value markets. Finally, certification should be duly encouraged among smallholder mango farmers to ease their access to and participation in high value mango markets.
