Despite the increase in forest areas and villages under the participatory program over the last two decades in Tanzania, there is little insight into the communities’ views regarding their participation. This study aimed to explore communities’ participation in the participatory forest program in Tanzania. The survey involved 159 households, randomly sampled from four villages bordering state and community-managed forests, in West Usambara Mountains. The factor analysis summarised three components of participation. Economic, decision-making, and protection activities are used to formulate the participation intensity index. The study observed significantly higher levels and intensity of participation in the villages around the state compared to those around the community forest. Training attendance, trust on institutions, and location were significant predictors of participation intensity of the households. In conclusion, the perceived performance of the participatory programs in achieving the participation aims has been moderate with better results in the state forest jointly managed with the community. Raising awareness and improving communication with villagers, fulfilling promises for the communities, and provision of more forest-linked interventions are recommended to improve the situation in West Usambara.

Small-holder farm households in developing countries mainly depend on rain-fed agriculture activities, thus seasonality affects eating habits and contributes to micronutrient deficiencies. This study assessed women’s dietary diversity score (WDDS) across three agricultural seasons in the Kapchorwa District, Uganda. In each season, 445 women with under five-year-old children from small-holder farm households were interviewed on socio-demographic characteristics as well as dietary practices between May 2016 and January 2017. Linear regression models estimated differences in WDDS across seasons. The mean WDDS at the lean, harvest and post-harvest seasons was 4.33 ± 1.21, 4.63 ± 1.30 and 4.36 ± 1.21, respectively. Mean WDDS was higher in urban regions across all seasons. Women in urban regions generated more income through off-farm activities, had better access to markets and consumed significantly more ‘meat, poultry and fish’ (p < 0.001), dairy products (p < 0.05), ‘vitamin A-rich fruits and vegetables’ (p < 0.001) and ‘other vegetables’ (p < 0.001) during the lean season, whilst rural women ate more dark green leafy vegetables (p < 0.001) during the same period. Poorer households in the rural setting were more likely to be affected by seasonally limited food availability and accessibility. Hence, strengthening the linkages between market participation, agricultural activities, improved food storage and preservation techniques and dietary intake is recommended.

Globally, governments and agricultural organizations implement policies and programs reflected in interventions such as input subsidies, extension services for modern inputs and training, which either enable or hinder agricultural diversification. A study was carried out from 2016 to 2019 in Lilongwe district, Malawi, to determine the influence of policies, programs and interventions on agricultural diversification. The study was using a mixed-method sequential explanatory design. It involved a literature review, interviews with 424 male and female smallholder farmers, 35 demonstration plots on agricultural diversification, 27 focus group discussions with farmers, and 17 key informant interviews with stakeholder representatives. The literature review showed that the 2016 Malawi agricultural policy already prioritized agricultural diversification as it included a policy statement and policy objective on agricultural diversification. This study found that stakeholders, namely the Ministry of Agriculture, Total Land Care, National Smallholder Farmers Association of Malawi, School of Agriculture for Family Independence, and Trustees of Agriculture Promotion Program, were promoting agricultural diversification. They did it by (i) organizing farmers into groups for agricultural diversification activities, (ii) provision of extension advice, and (iii) providing inputs for different crops as well as livestock either for free, on pass-on, or through loans. However, interventions were on small scale, had not fully addressed hindrances to agricultural diversification, were mostly supply-driven, and the interventions themselves faced sustainability-threatening problems such as failure to pass on livestock and seeds. The agricultural policy was thus not sufficiently translated into widespread programs and interventions to foster improvement in agricultural diversification. As such, we suggest re-channeling of funding from promoting mono-cropping to agricultural diversification by broadening the crop and livestock focus of advisory services, enabling farmer organization initiatives and community engagement for farmers to solve most diversification challenges on their own.
