Evolving rural food environments in South Asia: The role of processed foods, traditional markets, and marketing influences

Essential commodities prices, availability, and market actors’ perceptions: October 2025

Sudan’s markets in October 2025 showed relative stability with several commodities experiencing improved availability and quality. Wheat and wheat flour prices declined, while sorghum, millet, vegetables, lentils, meat, oilseeds, and sugar showed mixed but generally stable trends. Fuel prices fell early in the month before stabilizing, and fertilizer prices remained steady with better availability. Regional disparities persisted, with Darfur, Kordofan, and parts of Blue Nile continuing to record the highest prices for many goods due to conflict, transport disruptions, and liquidity constraints. Supply chain problems increased compared with September, driven by security concerns, high transport costs, exchange rate pressures, and limited cash access. Most merchants reported no major challenges related to storage, power, or hiring workers, although market safety concerns rose slightly, especially in North Darfur. Tax compliance increased at the federal level but remained highest at state and locality levels. Despite ongoing challenges, merchants continued to show resilience: over half plan to maintain current trade levels, nearly one-third expect to expand, and only small shares intend to reduce trade, change commodities, or relocate, although uncertainty increased modestly.

Vulnerability of Nigerian maize traders to a confluence of climate, violence, disease and cost shocks

Purpose We study five exogenous shocks: climate, violence, price hikes, spoilage and the COVID-19 lockdown. We analyze the association between these shocks and trader characteristics, reflecting trader vulnerability. Design/methodology/approach Using primary survey data on 1,100 Nigerian maize traders for 2021 (controlling for shocks in 2017), we use probit models to estimate the probabilities of experiencing climate, violence, disease and cost shocks associated with trader characteristics (gender, size and region) and to estimate the probability of vulnerability (experiencing severe impacts). Findings Traders are prone to experiencing more than one shock, which increases the intensity of the shocks. Price shocks are often accompanied by violence, climate and COVID-19 shocks. The poorer northern region is disproportionately affected by shocks. Northern traders experience more price shocks while Southern traders are more affected by violence shocks given their dependence on long supply chains from the north for their maize. Female traders are more likely to experience violent events than men who tend to be more exposed to climate shocks. Research limitations/implications The data only permit analysis of the general degree of impact of a shock rather than quantifying lost income. Originality/value This paper is the first to analyze the incidence of multiple shocks on grain traders and the unequal distribution of negative impacts. It is the first such in Africa based on a large sample of grain traders from a primary survey.
