A study led by Lancaster University, published in Nature Food, has proposed a solution to address poverty, improve milk production, and reduce greenhouse gas emissions in Tanzania by introducing high yield dairy cattle breeds and improving feed quality. With a poorly developed dairy sector and heavy reliance on imports, this strategy could potentially satisfy two key government policy goals: achieving milk self-sufficiency and reducing GHG emissions by one-third. The research, which involves modeling various scenarios, anticipates a decrease in the need for land use change and a reduction in forest clearance, contributing to a greener planet. However, it also highlights the need for support policies to prevent potential income drops for farmers who cannot afford to invest in higher yielding cattle.
