“…Findings in this study provide evidence that corroborates previous studies that have shown that innovative delivery of extension, improved technologies, and market services to farmers is important for enhancing productivity, revenues, and food security (Hoang et al, 2021 ; Katungi et al, 2018 ; Letaa et al, 2020 ; Nakano et al, 2018 ; Otsuka et al, 2016 ; Todo & Takahashi, 2013 ). Also, improved market access has been shown to increase farm productivity, by facilitating specialization, crop choice, and intensification in different parts of the world (Gafaro & Pellegrina, 2018 ; Kamara, 2004 ; Oppen et al, 1997 ).…”

“…Moreover, beans are the main legume (staple) consumed by households in the study area, thus increasing productivity could also increase food and nutrition security through consumption of iron and zinc reach bean types. Productivity gains from adopting improved bean varieties have been shown to improve household food security outcomes (Katungi et al, 2018 ; Letaa et al, 2020 ). Table 8 shows the effect of having indirect beneficiaries on productivity.…”

The quest to transform and hasten the role of smallholder farms in agricultural development and food security through farmer-firm linkages has dominated development interventions in low-income countries for several decades. This has mostly been pursued through single- or multi-contract schemes implemented in isolation. Several studies have analyzed the effects of these schemes on smallholder farms with mixed results. A new paradigm is to use Agricultural Public Private Partnership (Ag-PPP) to achieve wider and sustainable impacts. However, limited empirical evidence exists on the effects of Ag-PPP interventions and targeting the same farmer. We address this research gap by assessing the impact of an Ag-PPP on small-scale common bean producers in Uganda. We use a doubly robust difference-in-difference approach in a multi-treatment setting to estimate these impacts. The results show that the PPP created positive outcomes for farmers and stimulated increased production from targeted interventions. Evidence shows that the PPP and its interventions were associated with significant increases in productivity, sales volumes, and shares of output marketed. Receiving bundled interventions had greater effects than a single intervention and effects varied between men and women bean crop owners. Results suggest that providing bundled interventions through a PPP can increase productivity and alleviate market access constraints. The outcomes of this Ag-PPP could be modified for other contexts i.e., crops and localities, to inform food and development policy elsewhere.

“…This inter-disciplinary pipeline will serve boosting research capacity in the region, so that new knowledge, genotypes and practices are successfully uptake, maintained and scaled [44]. Long term partnerships with NGOs and municipal technology transfer offices will enable efficient delivery of promising adapted Liborino bean genotypes to farmer communities, and an effective tracing of their adoption [45] and impact [46].…”

Genotype Selection, and Seed Uniformity and Multiplication to Ensure Common Bean (Phaseolus vulgaris L.) var. Liborino

et al. 2022

Seed uniformity and stability testing, and multiplication, are key steps in the seed supply chain of the common bean (Phaseolus vulgaris L.) and other crops. Optimizing agronomical practices in these phases can ultimately ensure seed quality and availability, and germplasm prospective utilization. However, farmers have rarely standardized seed testing and propagation protocols in local common bean landraces conserved in situ. An example of this is the Liborino variety (var.), a promising yellow Andean common bean known for its presumably high digestibility and adaptation to the local conditions of the Cauca river canyon (northwest Andes of Colombia), but likely experiencing genetic erosion after decades of suboptimal propagation. Therefore, this work intended to evaluate and select locally adapted genotypes of common bean var. Liborino for commercial use, to be later multiplied, evaluated by participatory breeding, and eventually shared with farmers. Specifically, we evaluated 44 accessions of var. Liborino common bean in six adaption and yield field trials in the Cauca river canyon at 1100 and 1400 m a.s.l, and in AGROSAVIA’s “La Selva” research station at 2100 m a.s.l. In parallel, we carried out standardized seed multiplication of a Liborino genotype using best practices to guarantee uniformity and stability. From the 44 accessions, nine were well adapted to the tested local conditions. Four of these accessions exhibited a bush type growth habit, while the remaining five were climbers. The trials revealed maximum average extrapolated yields of up to 1169.4 ± 228.4 kg ha−1 for the bush types (G8152) and up to 1720.0 ± 588.4 kg ha−1 for the climbers (G51018), both at 2100 m a.s.l. Three climbing accessions matched farmers’ expectations for seed coat color and shape, according to a participatory selection exercise. Uniform and stable seed of the selected genotype was delivered in 2022 to 39 farmers, ~6.5 kg of seeds per farmer. Our results will allow implementing bean genetic improvement pipelines, promoting var. Liborino commercialization, and boosting the economic and sustainable development of the rural communities in the Cauca river canyon. Seed uniformity testing and multiplication pipelines must be extended to other bean landraces conserved in situ.

“…The survey conducted in 2016 interviewed households that were surveyed at baseline in 2013 and were selected through a three-stage stratified sampling method. The details of the sampling procedure are documented in Letaa, Katungi, Kabungo and Ndunguru [36] while this paper provides an overview of the sampling methods and data collection. The first stage involved listing 28 bean producing districts in the southern zone in accordance with the National Agricultural Census of Tanzania in 2012.…”

What Does Gender Yield Gap Tell Us about Smallholder Farming in Developing Countries?

This study examines the extent of the productivity gap between male and female bean producers, its discriminatory nature and implications for the policymakers in agriculture in Tanzania. Generally, women are distinctively “invisible” in agriculture, due to social norms and even from the national agricultural policy perspective. Their discrimination arises from uncounted and unaccounted for farm work, and their productivity is reduced by triple roles, limited access to education, having triple effects on access to technology, training and land rights. In research, issues of concern to them such as nutritious food crops, varietal selection on important attributes, household food security, convenient home storage and small-scale processing are widely ignored through unfavourable policy design. Given the above discriminatory issues surrounding women in agriculture, they are hypothesised to be less productive and often lag behind male counterparts in crop production. To test the above hypothesis, a three-stage stratified sampling method was used to collect cross-sectional data in 2016 across four regions of Tanzania. Then, an Oaxaca-Blinder decomposition method (at means) was used to apportion the sources of the difference between men and women into explained and unexplained variations. Further improvements through the newly developed Re-Centered Influence Functions (RIFs) remarkably improved outcomes as the differences were analysed through unconditional partial effects on quantiles. Using a counterfactual approach and correcting for selection bias, the model provided consistent estimates for easy comparison of the two groups. Besides this, it emerged that interventions such as providing improved bean seed varieties and training farmers on good agricultural practices reduced the gender yield gap and provided a potential avenue for addressing the discrimination observed in productivity among males and females. Controlling for selection bias also improved the model, but the real discrimination was observed at the 50th percentile, where the majority of the respondents lay within. However, if a female’s age, family size, additional years of schooling and discretion to spend income from beans were taken away, they would be worse off. Our study finds that females comprised 25 percent of the sample, had 6 percent lower productivity, provided 64.70 percent on-farm labour and had 0.32 hectares less land compared to males, ceteris paribus. Access to improved varieties contributed to a 35.4 percent improved productivity compared to growing indigenous/local varieties. The implication is that the gender yield gap can be reduced significantly if efforts are focused on preventing or correcting factors causing discrimination against women.
