“…However, FS advocacy tends to be driven by strong preferences for 'local' (Edelman et al, 2014) with local trade being hinged upon barter exchange (Marti and Pimbert, 2006;Pimbert, 2009). Yet, barter exchange faces challenges emanating from the absence of money and by the presence of indivisibility (Fujishige and Yang, 2021). In cases of excesses, connecting peasants to global markets may mean a complete set of certification procedures, creation of brands and appropriate standard setting, and benefit from excess produce marketed as specialty e.g., organic or community-traded products.…”

The recent discourse on food sovereignty places much emphasis on democracy in determining localized food systems, and whether the food is culturally appropriate while leaning heavily on sustainable agricultural practices such as organic agriculture, ecological intensification, agroecology, nature-based solutions, and regenerative agriculture. Sustainable agricultural practices are intended to ensure that the land is managed without the use of synthetic fertilizers and pesticides, while going further by focusing on improvements on soil and land health. However, what are the practicalities of food activism and relying entirely on nature while yields are still very low in much of sub-Saharan Africa (SSA)? We attempt to answer this question in four main sections: (a) we start by defining the concept of food sovereignty and the associated practices, (b) we highlight some of the main socio-ecological conditions that are common in SSA, and (c) we present evidence of some of the limitations of food sovereignty due to the diversity in ecological, political, cultural, and socio-economic contexts that characterize SSA; finally, (d) we focus on food preferences, marketing and certification aspects. We conclude that agroecology alone cannot solve the multiple objectives of increasing crop productivity and replenishing soil nutrients especially on small farms and relying on natural rainfall. There is an urgent need to combine superior crop varieties and judicious use of external inputs in tandem with the manipulation of the agroecological processes to increase the efficiency of input use and achieve higher food productivity, resilience to climate change, and preservation of the natural resource base in specific locations.

“…Ye et al, (2018) conducted an empirical study on the P2P online book barter market and concluded that an increase in the interaction frequency of participants improves barter efficiency [17]. Fujishige and Yang (2021) explained the reasons for the widespread existence of barter markets with an improved Markovian core [18].…”

Trade Credit with Barter in a Capital-Constrained Supply Chain

Barter has emerged to alleviate capital pressure, maximize the circulation of goods, and facilitate the disposal of excess inventory. This study considers a two-level supply chain consisting of a manufacturer and a capital-constrained retailer with trade credit, in which the retailer exchanges unsold products for needed subsidiary products on a barter platform. The retailer’s optimal order quantity and the manufacturer’s wholesale price are derived, and the influences of barter and other factors on the equilibrium strategy and performance of the supply chain are examined; these results are verified and supplemented by numerical simulation. We find that the retailer can increase profit by bartering when facing highly uncertain demand, that the retailer’s optimal order quantity increases with the supply rate and demand for subsidiary products, and that both manufacturer and retailer benefit from the high supply rate of subsidiary products. However, barter induces the manufacturer to raise the wholesale price to prevent its profit from being harmed. In addition, the manufacturer suffers from the retailer’s initial capital.

“…Bartering, the direct exchange of commodities and services without using money or any medium of exchange, is the oldest form of commerce [4] and a focus of study dating back to British economist Alfred Marshall [7]. Since that time, formal models of barter markets have been provided using the language of microeconomics and cooperative game theory [3,15,10].…”
