Assessing the profitability and feasibility of climate-smart agriculture investment in Southern Malawi


Book Description

This working paper analyses the financial cost and benefit of adopting two different bundles of climate-smart agriculture (CSA) practices, which are tailored for the diverse conditions that prevail in southern Malawi. The results show the integration of CSA practices, including soil conservation, agroforestry, and livestock diversification, into conventional maize-legume and maize monocrop systems is profitable for farmers. Moreover, the profitability of these systems increases under extreme weather conditions that occur with increasing frequency in the region. However, the upfront costs and cost variability associated with the adoption of these CSA scenarios is high relative to conventional practices. In addition, while the Net Present Value is positive for the CSA scenarios, the monetary returns are small and are spread over a long investment period. These factors act as significant barriers to adopting CSA practices. Supporting farmers through climate financing or other mechanisms to make long-term private investment in CSA, based on the public benefits these investments generate for the environment, is critical for achieving widespread adoption.

Profitable Squab Breeding


Book Description

"Profitable Squab Breeding" is a complete guidebook on the business of rearing squabs by author Carl Dare. The consumption of squab meat had steadily risen at the time of the books writing in the early twentieth century and Dare points out that, "The rearing of squabs for market is immensely profitable as well as easy. Squab-raising can be conducted on a scale large enough to make it worthwhile in the back yard of a town lot, or it can be conducted on a scale large enough to require several acres with equal profit on every dollar invested in the business. Squab-breeding is a business which is profitable when conducted as a side line on a small space and all the work may be done by women, children, or those who are not strong enough for the more laborious occupations of life. At the same time it is a business which men of affairs need not hesitate to undertake as there are squab farms on which pigeons are kept by tens of thousands with great profit."
