16 pages, Background
An estimated 140 million people in Africa face acute malnutrition. By impacting agricultural production, climate change is likely to further decrease food consumption, particularly in sub-Saharan African states. Against this backdrop, various actors have called for more attention to alternative farming and food systems based on traditional agricultural knowledge capable of ensuring access to sufficient, nutritious, and safe food. So far, however, we have limited systematic evidence on which traditional agricultural practices may promote the food resilience of households exposed to extreme climatic conditions. Focusing on the most prevalent traditional diversification practices in Tanzania, this study assesses the extent to which crop diversification, annual crop intercropping, crop-tree intercropping, crop-livestock integration, and the cultivation of traditional crops increase the food availability and dietary diversity of smallholders facing extreme weather events in Tanzania.
Methods
We combine temperature and rain data with information on farming practices and food consumption information provided by the Living Standards Measurement Study–Integrated Surveys on Agriculture for more than 25,000 Tanzanian households nationwide. We rely on a matched differences-in-differences approach to account for selection bias and allow for causal inference.
Results
Our matching models consistently show that the planting of traditional crops (in particular sorghum) promotes dietary diversity and reduces the need for food rationing in households experiencing climate shocks. In contrast, households relying on maize cultivation show less dietary diversity and increased food rationing behavior. In addition, we find that—under extreme weather conditions—crop diversification furthers households’ dietary diversity, and crop-livestock integration, as well as crop-tree intercropping, seem to reduce households’ need to ration food.
Conclusion and policy recommendation
This study has important implications for policymakers. In light of climate change and weather variability, it underscores the need to better integrate indigenous knowledge into farming systems. Our results call for greater dissemination of traditional diversification strategies and more reliance on indigenous, drought-tolerant crops. Traditional farming practices can function as a safety net, protecting smallholders in Tanzania against the detrimental consequences of weather shocks.
9 pages, Despite agriculture’s great potential to Tanzania agricultural development, the sector faces diverse challenges. For example, existence of gender gaps in accessing agricultural production resources and benefits obtained from the same impede the sector’s growth. Therefore, adoption of conservation agriculture (CA) has been seen as one of the measures to address the sector limited productivity. Nonetheless, there is limited knowledge on how CA has managed to reduce gender inequalities in accessing both reproductive resources and benefits accrued from agriculture. This paper examines gender gaps in conservation agriculture programme implemented by Sustainable Agriculture in Tanzania (SAT), by specifically analyzing gender participation and relations in CA in Morogoro municipality and Morogoro district. This study adopted a mixed method approach whereby both qualitative and quantitative data were collected from four sites where SAT implements its activities. Findings show that CA has significantly reduced gander gaps in accessing production resources and services as well as raising women’s participation in decision making with regards to production and use of income obtained from sales of produce. Farmers regardless of the gender can access extension services, and credit, and are involved in various initiatives collectively. Despite the economic benefits, findings show that CA is laborious and takes much of farmers’ time, women being more affected. Therefore, it is recommended that the central and local governments and various stakeholders should promote the spread of conservation agriculture technologies since it reduces the biasness in agriculture and empowering women. Ensuring access to advanced cheap technologies to farmers. Nonetheless, there is need to ensure that female farmers are not overburdened in the process.
11 pages., Declining crop productivity is a great challenge facing smallholder farmers in Tanzania. Agro-ecological practices can improve crop productivity in a sustainable way and produce healthy food among smallholder farmers. Initiation of “Farmer-Led Research of Agro-Ecological Practices” (FLRAG) may enhance farmers’ capacities for innovation and co-develop suitable agro-ecological practices. This study aimed at identifying factors influencing smallholder farmers to participate in FLRAG. A cross-sectional survey was used to collect qualitative and quantitative data from 90 smallholder farmers in Mvomero, Bagamoyo and Masasi districts in Tanzania. Data were also collected from key informants who were extension officers. The study identified that experience in farming, easiness in accessing agro-ecological inputs, interest in doing experiments and farm size ownership are the factors that substantially influence smallholder farmers to participate in FLRAG. Therefore, researchers are advised to select participants of FLRAG by considering the mentioned factors. Furthermore, farmers selected to participate in FLRAG are advised to the use of ugunduzi app” that was developed purposefully to enhance agro-ecological research in order to test and understand its potential on smoothing agro-ecological research activities.

9 pages, This study investigates how communication channels to exchange agricultural information were chosen. Specifically, it identifies the communication channels used by farmers in Tanzania and determines the factors influencing the choice of communication channels for exchanging agricultural information. The study employs a meta-analysis review methodology in identifying, evaluating and interpreting studies relevant to the topic of interest. The results indicate that radio, mobile phones, television, fellow farmers, agricultural extension agents and newspapers were the commonly used communication channels for transferring agricultural information. Moreover, the channels’ influence, availability, affordability, communication network coverage, and the resources and facilities needed to use a particular communication channel were found to influence the choice of channels. It is concluded that understanding the audience, the characteristics surrounding messages and choosing appropriate communication channels are important for enhancing access to agricultural information. It is recommended that agricultural information providers should understand the factors surrounding communication channels before disseminating agricultural information
21 pages, Online via UI Library electronic subscription, Research identifies farmer doubts about fertilizer quality and reveals that farmer beliefs are inconsistent with reality. However, many fertilizers have degraded appearance.
17 pages., This study examined the effectiveness of the channels used to deliver agricultural information and knowledge to smallholder farmers in Tanzania. A descriptive cross-sectional design alongside quantitative and qualitative approaches was employed to collect data from 341 respondents. While the data collected through the questionnaire was analysed by using Statistical Product and Service Solutions (SPSS) version 21, the data collected through the interview was analysed by using thematic analysis. The findings suggest that delivery of and access to timely and relevant agricultural information and knowledge, appropriately packaged, is one of the critical problems undermining smallholder farmers’ efforts to increase their production. As a result, most smallholder farmers mainly depend on informal channels. Besides informal channels, farmer groups and demonstration plots are becoming popular channels to deliver and access agricultural information and knowledge. To make a difference in agricultural production, deliberate efforts should be made to enhance the delivery of agricultural information and knowledge.

16 pages., Mobile phone use is increasing in Sub-Saharan Africa, spurring a growing focus on mobile phones as tools to increase agricultural yields and incomes on smallholder farms. However, the research to date on this topic is mixed, with studies finding both positive and neutral associations between phones and yields. In this paper we examine perceptions about the impacts of mobile phones on agricultural productivity, and the relationships between mobile phone use and agricultural yield. We do so by fitting multilevel statistical models to data from farmer-phone owners (n = 179) in 4 rural communities in Tanzania, controlling for site and demographic factors. Results show a positive association between mobile phone use for agricultural activities and reported maize yields. Further, many farmers report that mobile phone use increases agricultural profits (67% of respondents) and decreases the costs (50%) and time investments (47%) of farming. Our findings suggest that there are opportuni- ties to target policy interventions at increasing phone use for agricultural activities in ways that facilitate access to timely, actionable information to support farmer decision making.
11 pages., In 2016, a study was conducted in Tanzania to assess the impact of radio and SMS in scaling-up smallholder participation in legume-based sustainable agricultural intensification (SAI) practices and technologies. The study aimed to answer the following research questions: (i) does participation in the campaign enhance farmers’ knowledge of legume-based sustainable agricultural intensification practices and technologies? (ii) what is the impact of the campaign on the adoption of legume-based sustainable agricultural intensification practices and technologies?; (iii) does exposure to multiple ICT-enabled channels result in larger gains (in terms of knowledge and adoption) than exposure to only one channel? (iv) is it more cost-effective to use radio or SMS alone or use them in combination? The results show that both awareness and adoption are boosted if SMS supports radio campaigns. However, radio alone is the most cost-effective approach. Each dollar spent on the radio campaign results in 2.1 farmers that have adopted at least one new practice, compared with 0.5 farmers for SMS and 0.4 farmers for radio and SMS combined. Other factors were also important in facilitating uptake of legume-based SAI practices, such as gender, age, education and land size, but were not statistically significant when rated against the communication channels used.
