Empirical assessment of onion supply chain constraints in Bangladesh: A pre-covid to covid situation

In Bangladesh, Covid-19 has wrecked devastation on people's livelihoods and economies. It began with supply chain disruptions affecting a variety of agricultural products, particularly perishable ones. Onion, the most consumed species in Bangladesh and Asia is also fallen into that category. The goal of this study was to shed light on the current onion supply chain as well as the constraints faced by the actors in Bangladesh's major onion-producing area markets (i.e., Pabna, Rajshahi, and Chapainawabganj). The extent to which pre-existing constraints on market actors of onion were discovered and distinguished in pre-covid to covid conditions. The backward supply chain analysis revealed that the local market seller supplied the majority of necessary farm inputs (i.e., seed, seedlings, and fertilizer). Wholesalers, commission agents (aratdars), local wholesalers (beparies), and retailers were all involved in forward connecting. Producers received roughly 71% of the retail price (0.76/kg), followed by retailers (BDT 2.07/kg), wholesalers (BDT 1.22/kg), commission agents (aratdars) (BDT 0.85/kg), and independent wholesalers (beparies) (BDT 0.36/kg). Moreover, a constraint factor index and econometric analysis were utilized to determine the most critical constraints and their influencing factors. Obstacles to onion production and commercialization ranged from moderate (66%) to severe (33.5%), with a few being fairly severe (0.5%). The paucity of high-quality seed, the cost and difficulty of timely transportation, and the market's inaccessibility to government intervention were all significant drawbacks to increased onion output. The primary impediments to onion marketing were a lack of or inability to receive marketing expertise, frequent demand fluctuations, and an insufficient storage facility for other market intermediaries. The findings of the study can assist in establishing a dynamic policy framework that includes procedure for expanding market infrastructure, rehabilitating current onion market actors through adequate training, assuring information abundance, and rapidly addressing market mishaps for ensuring sustainability.

Sustainability and efficiency analysis w.r.t adoption of climate-smart agriculture (CSA) in Pakistan: a group-wise comparison of adopters and conventional farmers

Climate change, conventional agricultural management practices, and increasing water scarcity pose a major threat to agricultural production and biodiversity as well as environmental sustainability. Climate-smart agriculture (CSA) is recognized as an efficient, sustainable, and feasible agricultural system that plays a vital role in addressing the potential impacts of climate change in Pakistan. First-hand information was collected from 450 farm households in 24 villages from Okara, Sahiwal, and Khanewal irrigation divisions, having various wheat-based cropping systems of Pakistan. This includes rice-wheat (RW), maize-wheat (MW), and cotton-wheat (CW) cropping systems in the Lower Bari Doab Canal (LBDC) irrigation system. This study estimated and compared the sustainability and efficiency analysis of CSA and conventional agricultural practices. This study also estimated the impact of water-smart practices of the CSA, technical training, and groundwater quality on agricultural production by using production function and bootstrap truncated regression. The findings of this study revealed that adopters of CSA of the wheat-based cropping systems have higher economic benefits and improved resource use efficiencies compared to the conventional farmers. The findings of the study also revealed the increased efficiency of CSA adopters over other two systems in CW cropping system. The water-smart practices of CSA, access to credit, technical training, use of groundwater of varying quality, and other inputs also showed variations in the agricultural production and resource use efficiency. It has been concluded that farmers can earn more profit, save inputs (such as water), and increase their production by adopting water-smart practices of CSA. Hence, the government and other relevant institutions should devise and implement policies that adequately addressed the importance and enhance the use of water-smart practices of CSA in Punjab and beyond.

Ethnopharmacological values of cassava and its potential for diabetes and dyslipidemia management: Knowledge survey and critical review of report

Background:

Beyond nutritional values are the pharmacological potentials of cassava comparative with other staple carbohydrate plant-based foods such as wheat. The knowledge of applicability to diabetes and its cardiovascular complications management seems not just limited but unacknowledged. As a preliminary study, a community’s knowledge of pharmacological value of cassava is investigated.

Methods:

Descriptive observational study using questionnaire-based “cross-sectional” survey was conducted. 136 Participants completed the survey and 101 respondents were selected for evaluation. Open-ended questions were used qualitatively to generate experience and view cassava values for diabetes and dyslipidemia. While categorical (yes or no) questions were used quantitatively to generate numerical results for diabetes, critical reanalysis of a report data was performed, especially comparing carbohydrate/fiber and fat/fiber ratios of cassava with wheat in view of dyslipidemia.

Result:

On the positive side, 42% of the participants believe that cassava has medicinal values. This includes 6% (among the 42) who believes that the plant is useful in treating diabetes and 24% who do not know it may be useful in diabetes management. Critical review showed that cassava may contribute up to sixteen times more fiber and four times less digestible sugar, as well as carbohydrate/fiber and fat/fiber ratios being 14 and 55 times less than wheat.

Conclusion:

There is evidence that relative to wheat flour meal, for instance, cassava contributes less fat and much more fiber. Since fat is pro-obesity, which in turn is pro-diabetic/metabolic syndrome; and fiber is anti-dyslipidemic; cassava has pharmacological values to be appreciated over some carbohydrate plant-based foods.

The political economy of maize production and poverty reduction in Zambia: analysis of the last 50 years

Poverty and food security are endemic issues in much of sub-Saharan Africa. To eradicate extreme poverty and hunger in the region remains a key Millennium Development Goal. Many African governments have pursued economic reforms and agricultural policy interventions in order to accelerate economic growth that reduces poverty faster. Agricultural policy regimes in Zambia in the last 50 years (1964–2008) are examined here to better understand their likely impact on food security and poverty, with an emphasis on the political economy of maize subsidy policies. The empirical work draws on secondary sources and an evaluation of farm household data from three villages in the Kasama District of Zambia from 1986/87 and 1992/93 to estimate a two-period econometric model to examine the impact on household welfare in a pre- and post-reform period. The analysis shows that past interventions had mixed effects on enhancing the production of food crops such as maize. While such reforms were politically popular, it did not necessarily translate into household-level productivity or welfare gains in the short term. The political economy of reforms needs to respond to the inherent diversity among the poor rural and urban households. The potential of agriculture to generate a more pro-poor growth process depends on the creation of new market opportunities that most benefit the rural poor. The state should encourage private sector investments for addressing infrastructure constraints to improve market access and accelerate more pro-poor growth through renewed investments in agriculture, rural infrastructure, gender inclusion, smarter subsidies and regional food trade. However, the financing of such investments poses significant challenges. There is a need to address impediments to the effective participation of public private investors to generate more effective poverty reduction and hunger eradication programmes. This article also explores the opportunities for new public–private investments through South–South cooperation and Asia-driven growth for reducing poverty in Zambia.
