The recent Global Climate Report released by the World Meteorological Organization shows that 2023 was the warmest year on record, with the global average near-surface temperature at 1.45°C above the pre-industrial baseline indicates that climate extremes are the aggravating factors that triggered food insecurity and other effects of climate change in 2023. For example, the number of people who are acutely food insecure worldwide has more than doubled, from 149 million before the COVID-19 pandemic to 333 million in 2023 in 78 countries monitored by the World Food Programme.
There are several interventions being implemented by governments and development partners to build resilience against climate change, however, it is still not enough. Should current increasing temperatures that are contributing to food insecurity frighten decision-makers, or should they explore the opportunities it offers? This blog delves into this pressing question and suggests solutions and pathways for a resilient agri-food system in Ghana.
Understanding climate change impacts on the agrifood system
In Ghana, as in many African and Asian countries, the agri-food system remains pivotal in ensuring both food security and economic development. The agri-food system represents the interactions between and within the bio-geophysical and human environments, where diverse activities such as food production, processing, packaging, distribution, retail, consumption and waste management occur. The system serves as the primary source of livelihood for a significant portion of the population and is at the core of achieving most of the Sustainable development goals (e.g., Goals 1, 2, 3). However, the challenges posed by climate change and variability are making the agri-food system less resilient and sustainable to meet the growing demand for sufficient and nutritious food.
In regions heavily reliant on agriculture, and very sensitive to the impacts of climate change and variability such as northern Ghana, smallholder farmers who are entirely dependent on rain-fed agriculture are the most vulnerable. For instance, findings from the European Union-funded Resilience against Climate Change-Social Transformation Research and Policy Advocacy project, implemented by the International Water Management Institute, indicate that climate change effects are already being felt on agriculture and food security. The most pronounced negative impacts are occurring in climate-vulnerable regions such as the Upper West and Savannah regions, which serve as the food basket of the country. The effects of climate change, particularly through higher temperatures, water shortages, the disruption of ecosystems and the loss of biodiversity in the regions generate significant impacts on the different dimensions of food security. These effects include a reduction in crop productivity, water scarcity exacerbating food insecurity, and highlighting the urgency for resilience-building within the agri-food system.
Innovations for building resilience
While climate risks warrant careful attention, it is not the time to despair. Rather, shouldn’t stakeholders leverage the opportunities offered by the impacts of the changing climate to drive catalytic positive transformations in agriculture and food production?
Advancements in technology offer promising avenues for addressing climate change impacts to enhance agricultural productivity. Precision agriculture, for instance, utilizes data-driven approaches such as satellite imagery, drones and sensors to optimize resource use and minimize environmental impact. By accurately targeting inputs such as water, fertilizers and pesticides, farmers can increase efficiency and reduce greenhouse gas emissions.
Furthermore, the development of climate-resilient crop varieties through breeding and biotechnology holds immense promise for ensuring food security in a changing climate. Scientists are working to engineer crops that are drought-tolerant, heat-resistant and pest-resistant to enhance the productivity of smallholder farming.
