Climate-smart agriculture (CSA) offers a vital solution to the dual challenges of climate change and food insecurity. With global food production needing to double by 2050 to meet the growing food demand, and traditional farming practices struggling under extreme weather events, CSA integrates innovative techniques to enhance productivity, build resilience, and reduce emissions. As farmers face these mounting pressures, can CSA be the key to securing a sustainable and resilient future for agriculture?
Climate change and food insecurity stand as the two most critical challenges facing humanity in the 21st century. The agriculture industry is no exception. It is under immense pressure to meet the growing demands of an expanding global population, all while grappling with big challenges of climate change and decreasing availability of arable land. Depleting nutrition of the soil further adds to the misery.
With the world having lost about a third of its arable land in the last 40 years, and cities expanding at unmatched rates, the UN predicts we will need to double food production by 2050 to sustain humanity. The farming sector, already the hardest hit by climate change, faces an increasingly unstable environment, with heatwaves, floods, and droughts drastically reducing and affecting crop yields. The traditional farming methods struggle to keep pace and the industry is being forced to innovate, adapt to new technologies to maximize efficiency and production all while minimizing costs. With climate change reshaping the face of agriculture, farmers must adapt to protect both their livelihoods and global food security.
In September 2015, world leaders from 193 United Nations member states adopted the Sustainable Development Goals (SDGs), a powerful international framework aimed at eradicating global poverty while addressing interconnected issues of inequality, hunger, and climate change by 2030. At the heart of achieving these goals lies the urgent need for a climate-smart food system. One that not only can nourish a growing population but provide sustainable livelihoods, and conserve our natural resources.
As climate change intensifies, agriculture remains one of the most vulnerable sectors, accounting for 19-29% of total greenhouse gas (GHG) emissions. Extreme weather events such as heatwaves, droughts, and floods threaten traditional farming practices and the productivity of agricultural systems, pushing farmers to reassess their methods. As mentioned, the reality is that global food production must increase by 60% by 2050 to meet the demands of a rapid growth in population, projected to reach nearly 10 billion people by the middle of the century. The agriculture sector must focus not only on quantity but also on quality and long-term sustainability. The UN estimates that we must double our food production while simultaneously reducing emissions and enhancing resilience against climate-related shocks.
Climate-smart agriculture (CSA) is emerging as a viable solution. This approach focuses on managing agricultural systems to tackle the challenges of food security and climate change. It works on enhancing traditional farming methods like nutrient management, cover cropping, and conservation tillage to adapt to changing climate conditions and minimize future risks. By improving food security, CSA can help farmers maintain and increase yields, which is critical and the need of the hour. Moreover, CSA practices aim to reduce GHG emissions, prepare farmers for current and future climate impacts, and improve soil health. Defined in a 2010 report by the Food and Agriculture Organization (FAO) of the United Nations, CSA encompasses a set of practices focused on three main goals: increased productivity, enhanced resilience, and reduced emissions.
Keya Salot, founder of Farm2Fam, emphasizes the transformative potential of CSA: “With increased global warming, the key challenge for the farming community is to ensure the adaptability and good health of the plants in the ever-changing climatic conditions. One of the solutions to the problem of adaptation of plants is climate – smart agriculture. With controlling the UV radiation and trapping / release of the heat, it is possible to enable the plants to be healthier in the existing window of production.
CSA incorporates various practices and technologies, including climate-resilient crop varieties, conservation agriculture techniques, agroforestry, precision farming, and improved water management. Examples of climate-smart technologies include direct seeded rice (DSR), drum seeders, and micro-irrigation. These approaches yield multiple benefits:
Despite the advantages, some critics argue that CSA lacks universally accepted standards, raising concerns about potential greenwashing by large corporations. The cost-benefit analysis of CSA is compelling. The cost of adaptation is estimated to be around US$ 160 million annually between 2010 and 2050, but the savings from adaptation actions are projected to be much greater.
Climate-smart agriculture is an important tool for addressing the many challenges of climate change and food security. By adopting these innovative practices, farmers can improve their livelihoods while contributing to a sustainable future. CSA is not just a set of practices, it is a critical pathway for an agricultural system that is resilient against extreme weather patterns and can effectively withstand both current and future environmental challenges.
