Most cocoa farmers in Ghana do not adopt research recommendations because they cannot afford the cost, therefore, yields are low. Integrated pest management (IPM) technologies that rely on low external inputs were tried with a group of farmers. The technologies included using aqueous neem seed extracts to control capsids; removing diseased pods to reduce blackpod incidence; controlling mistletoes, epiphytes, weeds; and managing shade. Although yields increased significantly, adoption was constrained by technical, social and economic factors.
According to the authors of this paper, actual methods of scaling are rather empirical and based on the premise of ‘find out what works in one place and do more of the same, in another place’. These methods thus would not sufficiently take into account complex realities beyond the concepts of innovation transfer, dissemination, diffusion and adoption. As a consequence, scaling initiatives often do not produce the desired effect.
The Cold Chain Bangladesh Alliance (CCBA) aims to increase the availability, access, and use of domestically‐produced and nutritious foods in an effort to sustainably reduce poverty and hunger.
Present refrigeration and cold transport technologies typically use either diesel fuel (expensive and a source of pollution) and/or electric power (often not available in rural areas). Promoting the expansion of existing technologies for cold-chain development will have the side effects of increasing pollution, greenhouse gas production and associated climate change. Clean cold-chain development is an environmentally sustainable way to achieve essential cooling and reduction in the post-harvest losses.
The privatization of agricultural research and extension establishments worldwide has led to the development of a market for services designed to support agricultural innovation. However, due to market and systemic failures, both supply side and demand side parties in this market have experienced constraints in effecting transactions and establishing the necessary relationships to engage in demand-driven innovation processes.
