This study examined the trend in climate in Ghana, how smallholder horticultural farmers perceive this changing climate and how they are responding to its perceived effects. A survey of 480 resource-constrained horticultural producers was conducted in two municipalities of Ghana. Descriptive analysis and Weighted Average Index were employed to rank identified adaptation strategies and challenges. The results showed that farmers are already experiencing increasing temperature and declining rainfall patterns consistent with trends of observed climate changing in the last two decades.
In this article, wes developed a quantitative model to compare HT and CF supply chain finance schemes with each other and with traditional, fixed-price delivery contracts, which we identify as Soft Tolling (ST). We make this comparison in the setting of a three-echelon agricultural supply chain, where the third echelon is a large, creditworthy food/beverage manufacturer. This article proceeds as follows: the next section discusses related literature. Section 3 presents our model of an agricultural supply chain and the three specific contract variants (ST, HT, or CF) that we study.
The innovations of this paper lie in the establishment of a multi-product supply chain model composing of a farmer cooperative and a supermarket in which the farmer cooperative supply multiple types of agricultural products to the supermarkets rather than single type of agricultural product. The study started by studying the optimal decision-making behavior of the members of the supply chain in non-coordinated modequantitatively. Then, was applied the revenue-sharing contract to coordinate the mode.
This paper used systematic literature network analysis to review the state-of-the-art blockchain technology including its recent advances, main applications in agri-food value chain and challenges from a holistic perspective. The findings suggest that blockchain technology together with advanced information and communication technology and internet of things have been adopted for the improvement of agri-food value chain management in four main aspects: traceability, information security, manufacturing and sustainable water management.
The present chapter outlines a descriptive analysis of the sorghum value chains across the globe, the identified major constraints of the sorghum value chain, the business service provisions, and suggested specific areas of interventions for upgradation of the value chain. Considering the VC of sorghum, it is very new and value addition is limited up to harvesting and marketing of whole sorghum grain.
This review paper responds to the following questions: 1) can existing adaptation options confer useful responses to various degrees of climate change; 2) have certified coffee programs already implemented adaption options; 3) what (additional) implementation steps are required to adapt coffee production to climate change; and 4) which social-institutional changes are additionally required to enable smallholders to adapt to climate change at farm and landscape scales.
The objective of the study was to identify a viable trade-off between low data requirements and useful household-specific prioritizations of advisory messages. At three sites in Ethiopia, Kenya, and Tanzania independently, we collected experimental preference rankings from smallholder farmers for receiving information about different agricultural and livelihood practices. At each site, was identified socio-economic household variables that improved model-based predictions of individual farmers’ information preferences.
While a number of works question the alterity of alternative food chains, little has been said about the social processes under which new economic models are, or may be, developed within the broader movement around ‘short food supply chains’ (SFCs) in Europe. Considering SFCs as economic organisations, we propose an analytical framework based on New Economic Sociology and Convention Theory, enriched by Social and Solidarity Economics, to capture the social construction of new economic models in such chains.
This study was part of a larger project that applied an integrated framework for combined nutritional, food safety and value chain analysis to assess the dairy value chain in two regions of Tanzania, namely Morogoro and Tanga. Here, we report on the use of participatory rural appraisals (PRAs) with producers and consumers to investigate seasonality, constraints and opportunities in cow milk production and consumption in ten villages in Tanzania and describe attitudes and practices surrounding milk quality and safety.
Conflicts of interests have been hypothesized when agricultural advisory services are connected to agri-input businesses. However, these have not been examined using large sets of advisory service and grower data. We provide quantitative insights into dependencies between service, crop production, sustainability and the level of agri-input business-linkage of extension workers. This study analyzed 34,000+ prescription forms (recommendations) issued to growers in China, as well as grower interview data.
