Smallholder farmers in developing countries often suffer from high risk and limited market access. Contract farming may improve the situation under certain conditions. Several studies analyzed effects of contracts on smallholder productivity and income with mixed results. Most existing studies focused on one particular contract scheme. Contract characteristics rarely differ within one scheme, so little is known about how different contract characteristics may influence the benefits for smallholders.
The challenge of food security in Nigeria hinges on several factors of which poor technical efficiency is key. Using a stochastic frontier framework, we estimated the technical efficiency of agricultural households in Nigeria and tested for the significance of mean technical efficiency of food-secure and food-insecure agricultural households. We further assessed the determinants of agricultural households’ inefficiencies within the stochastic frontier model and adopted a standard probit model to assess the determinants of households’ food security status.
The study responds to the request by farmers in the Hohoe and Jasikan Rice Innovation Platforms, to identify traders and consumers’ rice preferences to enable them produce rice varieties that meet users’ demands. The study provided strategic guidelines for the development of a marketing and promotional plan for locally produced rice in Ghana. The report is structured as follows: Chapter one introduces the study including the study objectives, design and methodology.
This article presents a multi-stakeholder framework for intervening in root, tuber, and banana seed systems and in other VPCs. These crops are reproduced not with true seed but with vegetative planting material (e.g., roots,tubers, vines, stems, and suckers), called “seed” in this article. Seed systems for VPCs need to be designed differently than those for true seed, and coordination among stakeholders in seed systems is crucial
The main goal of the study is to quantify the effects of a) change in nitrogen fertilization rate, b) adjustment of sowing date, c) implementation of new cultivars, and d) supplementary irrigation on maize cropping systems across six African countries including Ghana, Nigeria, Kenya, Malawi, Ethiopia and Burkina Faso. For this purpose, 30 years (1980-2010) of climate data are used as well as soil and management information obtained from global datasets at 0.5° x 0.5° spatial resolution.
The paper is based on the analysis of cooperation in two different German case studies: One case deals with the development of a sustained value chain for ethical poultry production while the other case aims at the combination of different niche innovations for cultural landscape conservation. The empirical analysis is based on the categories ‘goals of the innovation and motives of cooperation’, ‘actors and their resources’, ‘distribution of costs and benefits’, ‘cooperation structure and management’.
This paper draws on data collected during 12 months of fieldwork in Northern Ghana. The fieldwork researched two communities in two districts of Northern Ghana and three Agricultural Development Agencies (ADA); Savanna Agricultural Research Institute (SARI), the Ministry of Food and Agriculture (MOFA) and World Vision Ghana (WVG). Data collection was achieved through formal surveys, Focus Group Discussions (FGDs) and observations. A total of 120 individual interviews were conducted for the formal survey guided by the questionnaire.
The present study investigates the value chain supplying school catering with organic produce, using the organic vegetable industry in the Berlin-Brandenburg region as an example. It employs a qualitative case study approach to explore industry actors’ perspectives and their activities within the value chain. Data is collected by conducting ten in-depth interviews with actors on different supply chain levels (farming, wholesale, and school catering) and is analyzed using qualitative content analysis
Iran faces environmental challenges such as erosion and extreme events, namely droughts and floods. These phenomena have frequently affected the country over the past decades and temperature rise has led to a more challenging situation. Iran started to implement national and provincial policies in the 1950s to cope with these phenomena. To provide an overview of Iran’s efforts to tackle land degradation and climate change, this paper examined through literature since 2000 the stakeholders’ policies, their interventions and obstacles to the mitigation of these environmental challenges.
This paper uniquely focuses on rapidly-developing domestic value chains in Africa’s emerging bioeconomy. It uses a comparative case study approach of a public and private cassava outgrower scheme in Ghana to investigate which contract farming arrangements are sustainable for both farmers and agribusiness firms. A complementary combination of qualitative and quantitative methods is employed to assess the sustainability of these institutional arrangements.
