INTRODUCTION
According to the World Bank, agriculture is responsible for up to 30% of the world’s greenhouse gas emissions. The farming industry generates these emissions through various means such as transportation, the cultivation, harvesting, and processing of crops as well as livestock production. Additionally, the use of pesticides, herbicides, and fertilizers in agriculture leads to water pollution.
Undoubtedly, there is a pressing need to decrease agriculture’s ecological footprint while simultaneously increasing productivity to sustain a rising global population. The world’s population stands at 7.7 billion and is anticipated to increase to 9 billion by 2050. Unfortunately, expanding urban areas and climate change are causing a decline in available agricultural land. As per the World Bank’s estimation, food production will need to grow by 70% by 2050 to bridge this gap.
This is where the significance of sustainable agriculture becomes apparent. According to the U.S. Department of Agriculture sustainable agriculture refers to practices designed to safeguard the environment, enhance the Earth’s natural resource reservoirs, and preserve and advance soil fertility.
What is sustainable agriculture?
Sustainable agriculture is a purposeful endeavor to conserve the environment, expand the Earth’s natural resource reserves, and simultaneously promote animal and human welfare. Its objective is to cater to the present food and textile demands of society while ensuring that future generations’ access to natural resources is not compromised.
Furthermore, sustainable agriculture contributes to preserving the environment by fostering soil quality, minimizing erosion, and conserving water. To promote sustainable practices, agriculturalists prioritize specific criteria, keeping pace with contemporary sustainability practices.
What are sustainable food systems?
Sustainable food systems (SFS) refer to a food production and distribution system that not only guarantees adequate access to food and nutrition for everyone but also upholds the economic, social, and environmental pillars necessary to produce food sustainably for generations to come. This means that:
It is economically sustainable, meaning it is profitable throughout
It has broad-based benefits for society, ensuring social sustainability
It should have a positive or neutral effect on the natural environment, ensuring environmental sustainability
The United Nations’ Sustainable Development Goals (SDGs) prioritize the establishment of a sustainable food system. Enacted in 2015, the SDGs demand substantial alterations in agriculture and food systems to eradicate hunger, accomplish food security, and enhance nutrition by 2030.
To achieve the SDGs, it is important to transform the global food system to become more productive, inclusive of impoverished and marginalized populations, environmentally sustainable, and resilient. Additionally, for sustainable food systems, it should be capable of providing wholesome and nutritious diets to everyone.
