Agroecology is the application of ecological concepts, the study of relationships between plants, animals, people, and their environment - and the balance between these relationships, and principals in farming.[1]

In the context of Food Sovereignty, localization, and Bioregionalism utilizing agroecology is key to transitioning away from and repairing the destructive effects[2] of industrial agriculture.[3]


Mycelium

Mycorrhizal symbioses is a powerful tool to be employed in agroecological settings. Mycelium is highly efficient in facilitating plan nutrient uptake, water distribution and overall crop production.[4][5] Mycelium is able to increase Phosphorus and Nitrogen uptake and use efficiency,[6][7] which is vital in the transition away from Industrial Agriculture and artificial fertilizers. Mycelium can also help plants adapt to bioitic and abiotic stressors- increasing overall crop quality.[8][9]

Agroecological Service Crops

Service crops are plants grown not for yield purposes, but to provide particular ecosystem services to the agrosystem. In no-till environments these crops can be utilized to prevent the spread of invasive weeds and do avoid detrimentally disturbing microorganisms in upper soil layers and mycorrhizal fungi.[10][11][12]

"Weeds"

Weeds are typically viewed in a negative light especially in the context of Industrial Agriculture. Looking at weeds through an agroecological lens shows how there are many practical uses and benefits to letting certain types of weeds grow. One example is spontoaneous flora promoting plant diversity and belowground interactions include Mycelium.[13]

World Hunger

[14]

Industrial Agriculture produces massive amounts of mono-cultured food stocks, but there are still millions of people across the globe who go hungry everyday or die from starvation. According to the 'Food Security Information Network' in 2022 258 million people across 58 countries/ territories faced high levels of acute food insecurity which was an increase from the 193 million people in 2021.[15]

Because not all countries were included in these studies the number of people who go hungry is much higher; Between 702 and 828 million people go hungry every day according to the 2022 'State of Food Security and Nutrition in the World' report published by a joint collaboration under the United Nations.[16] World hunger rose further in 2021 after the emergence of the COVID-19 Pandemic:

... After remaining relatively unchanged since 2015, the prevalence of undernourishment (PoU) jumped from 8.0 to 9.3 percent from 2019 to 2020 and rose at a slower pace in 2021 to 9.8 percent.

It is estimated that between 702 and 828 million people were affected by hunger in 2021. The number has grown by about 150 million since the outbreak of the COVID-19 pandemic – 103 million more people between 2019 and 2020 and 46 million more in 2021, considering the middle of the projected range.

The further increase in global hunger in 2021 reflects exacerbated inequalities across and within countries due to an unequal pattern of economic recovery among countries and unrecovered income losses among those most affected by the COVID-19 pandemic, all in a context of diminishing social protection measures that had been implemented in 2020.[17]

Even more people were moderately or severely food insecure in 2021 with the number reaching 2.3 billion or nearly 30 percent of the global population, which is 350 million more people than 2019 or before the COVID-19 Pandemic began.[18]


Gender Inequality

The gender gap in food insecurity – which had grown in 2020 under the shadow of the COVID-19 pandemic – widened even further in 2021, driven largely by the widening differences in Latin America and the Caribbean, as well as in Asia. In 2021, the gap reached 4.3 percentage points, with 31.9 percent of women in the world being moderately or severely food insecure compared to 27.6 percent of men.[19]
