Reasons for low uptake of climate change technologies
As the world grapples with rising food insecurity and greenhouse gases such as carbon dioxide and methane that trap heat in the atmosphere resulting in global climate change, there have been calls for urgent action.
Given that carbon dioxide contributes to most greenhouse gas emissions and crops need it for their growth, technologies that aid soil carbon sequestration — a process of removing carbon dioxide contained in the atmosphere through photosynthesis and storing it in vegetation and soils — have a double effect of tackling food insecurity and mitigating climate change.
These technologies include application of biochar, a charcoal produced from plant matter and used as soil manure, to aid soil carbon sequestration. Others include agroforestry, organic agriculture and use of green manure and mulching.
Most of these technologies are low-cost solutions for improving agricultural productivity, resilience and carbon sequestration. As a result, these technologies are attractive to smallholders.
But smallholders’ uptake of these technologies is low, and thus we need to rethink our approach to fighting climate change and food insecurity. Read the full article on SciDev.Net
