Nourishing the Earth To Tame the Climate: Digging the Potential of Sustainable Farming to Combat Climate Change

It’s no longer news that agricultural productivity has declined worldwide for different reasons. Agriculture heavily depends on land, water, and other natural resources, making it extremely vulnerable to climate change. Factors such as increasing temperatures, biodiversity loss, unpredictable growing seasons, and water scarcity adversely affect agriculture on a global scale.?

Food shortage is already a pressing issue, with almost 30% of the global population experiencing moderate to severe food insecurity in 2021. This number continues to rise, highlighting the urgency to address the United Nations' Sustainable Development Goal 2, which aims to eradicate hunger worldwide by 2030.

Agriculture is not just a victim of climate change; it also contributes significantly to global warming, in a dangerous cycle we must break. It accounts for around 25% of global greenhouse gas (GHG) emissions. Cultivating crops, raising livestock, and managing agricultural systems profoundly impacts our climate.?

This puts us in a difficult situation. We need agriculture for sustenance, but our current path poses a grave threat due to its significant GHG emissions.? We must then recognize the link between agriculture and climate change and find ways to produce food while combating climate change.?

Balancing these two objectives for our planet and our future is crucial.

Join me as we delve into the intricate relationship between agriculture and climate change. Together, we will explore #sustainablepractices that can pave the way for a thriving and resilient food system while we still have time.

1. The Impact of Agriculture on Climate Change

By understanding the direct and indirect ways agriculture continues to fuel climate change, we can develop effective strategies to reduce emissions and transition to sustainable farming practices.?

Agricultural practices that continuously weaken ecosystems' ability to provide essential services like carbon sequestration, pollination, and pest control include;

Direct Contribution

Livestock production, particularly from ruminant animals such as cows, sheep, and goats, plays a significant role in GHG emissions, primarily methane and nitrous oxide. Methane is produced during the digestive process of ruminant animals. At the same time, nitrous oxide is released through manure management and fertilizer use. These gases have a much higher warming potential than carbon dioxide (CO2), making livestock production a major contributor to global GHG emissions.

Additionally, livestock production requires substantial water, feed, and other resources. The water footprint of meat and dairy production is relatively high, contributing to water scarcity and depletion in certain regions.

Improper land management practices, such as intensive ploughing, deforestation, and inadequate erosion control measures, contribute to soil erosion. Eroded soil is carried away by runoff and ends up in water bodies, causing sedimentation. This sedimentation can harm aquatic habitats, smothering and destroying natural habitats, reducing water clarity, and impairing the health of marine ecosystems.?

Sediments may also carry pollutants such as pesticides and heavy metals, further polluting water bodies.

Synthetic fertilizers, especially nitrogen-based ones, release nitrous oxide, evoking a higher warming potential. When artificial fertilizers are applied to crops, soil microbes can convert excess nitrogen into nitrous oxide through nitrification and denitrification.

Overuse or improper application of synthetic fertilizers can result in runoff into nearby water bodies, leading to water pollution. Excessive nutrient levels in water systems can cause eutrophication, where the increased nutrients promote algae growth and deplete oxygen levels in aquatic ecosystems. This process releases carbon dioxide and methane.

Continuous dependence on synthetic fertilizers without appropriate soil management practices leads to soil degradation, reduced soil fertility, and decreased capacity for carbon sequestration. Healthy soils with high organic matter content serve as carbon sinks, helping mitigate climate change by storing carbon in soil organic carbon.

Indirect Contribution

Deforestation has significantly contributed to GHG emissions as the demand for more agricultural land grows. Forests act as carbon sinks, absorbing CO2 from the atmosphere through photosynthesis and storing it in their biomass and soils. Clearing them for agriculture or other purposes releases the stored carbon, increasing GHG concentrations.

The production of synthetic fertilizers and their transportation from manufacturing plants to agricultural fields relies heavily on fossil fuels, contributing to further emissions.

Land-use changes result in habitat loss for numerous plant and animal species, leading to biodiversity loss. This disrupts ecosystems' resilience and functioning, affecting their ability to sequester carbon and adapt to changing climatic conditions.?

When vegetation cover is removed or not adequately maintained, rainfall and wind can detach and carry away soil particles, leading to soil erosion. This process depletes the topsoil, rich in organic matter and nutrients necessary for plant growth. Soil erosion reduces agricultural productivity and leads to sedimentation in water bodies, impairing water quality and aquatic ecosystems.

Heavy machinery use and excessive tilling cause soil compaction. Compacted soils have reduced pore space, limiting water, air, and root growth infiltration. This hampers water drainage and root development, affecting plant health and productivity. Soil compaction also decreases soil resilience to drought and increases the risk of soil erosion.

Water sources for irrigation, such as rivers or groundwater, are depleted due to excessive water extraction, which exposes or dries riverbeds, decomposing organic matter in saturated soils. Moreover, poorly managed irrigation systems can result in waterlogging and salinization of soils, impairing their ability to sequester carbon and contribute to increased GHG emissions.

2. Why Should We Adopt Sustainable Farming Practices?

A 2015 report urged a quick shift to sustainable farming methods due to the alarming loss of about 33% of arable land worldwide. This situation has worsened with increasing global warming.

Current agricultural practices, a growing global population, and changing climate patterns demand urgent action to secure a sustainable future for our planet. If you're skeptical about the need for sustainable agriculture, here are some additional benefits to consider:

By supporting local producers, sustainable distribution systems enhance #foodsecurity, foster economic resilience in communities, and minimize disruptions caused by external factors, especially long-distance transportation.

• Consumption

This involves consuming locally sourced and seasonal foods, reducing food waste, and adopting healthier and more sustainable dietary patterns. By reducing meat consumption, choosing plant-based alternatives, and supporting sustainable farming practices through consumer demand, individuals contribute to the resilience of food systems and promote sustainable resource management.

Reduced Food Waste and Sustainable Dietary Patterns

Approximately one-third of all food produced for human consumption is lost or wasted, amounting to about 1.3 billion metric tons annually. This food waste decomposes in landfills, releasing methane and, ultimately, the global warming potential.?

This staggering amount of food waste represents a lost opportunity to feed the world's hungry population and exacerbates climate change.?

Therefore, reducing food waste is now a must-do to sustain our population. We can achieve this by reducing waste in every stage of the food chain or adopting sustainable dietary patterns. Both work in different ways toward a common goal.?

Reducing Food Waste:

Minimize Environmental Impact

When we waste food, we also waste the resources used to produce it, like water and energy. Less waste translates to more resources saved, hence fewer emissions.?

Alleviate Hunger and Food Insecurity

Food waste worsens global food insecurity. Most food thrown away from supermarkets, shops, and households is still suitable for consumption. This could feed millions of hungry people elsewhere if we employ practical food waste reduction.

Optimize Economic Efficiency

Food waste represents a significant economic loss. Individuals, businesses, and economies can save money and use resources more efficiently by minimizing such waste.?

2. Adopting Sustainable Dietary Patterns:

Reduce Greenhouse Gas Emissions

Animal agriculture contributes to high GHG emissions, especially in meat and dairy production. Shifting towards plant-based diets or reducing meat consumption can lower emissions and help mitigate climate change.

Preserve Natural Resources

Plant-based foods, whose production requires fewer resources than animal-based products, are a sustainable agricultural practice. Choosing them helps conserve water, land, and forests and protects biodiversity.

Promote Health and Well-being

Diets rich in fruits, vegetables, whole grains, and legumes offer health benefits and lower the risk of chronic diseases. Adopting them improves our health and lessens the burden on healthcare systems.

Support Food Security

By diversifying our food choices and reducing reliance on resource-intensive foods, we contribute to food security for all and global food availability. Sustainable diets promote a diverse and balanced food system, saving arable land from quick degradation. They also give us a larger scale of options, boosting food availability.

5. The Role Of Governments, Policymakers, And Businesses In Sustainable Agriculture?
