Q & A

What does the term 'sustainability' mean in the context of food and agriculture?

In the context of food and agriculture, 'sustainability' refers to practices that maintain a certain rate or level of production without jeopardizing the ecosystem's ability to meet future needs. It involves an ecosystem-wide approach that ensures the needs of today do not compromise the ability of the ecosystem to be there for tomorrow.

What is the speaker's educational background and how does it relate to their interest in agriculture?

The speaker studied at the University of Wisconsin-Green Bay Marinette campus and later at the University of Wisconsin-Madison, where they developed an interest in exploring outcomes and understanding the relationship between cause and effect. They found that agriculture, being at the core of science and biology, met their criteria for a career with a direct and measurable benefit to society.

What is the legal definition of 'sustainable' in relation to agriculture according to the speaker?

The legal definition of 'sustainable' in relation to agriculture is a series of farm-specific practices that work together to ensure human needs for food and fiber are met while improving the on-farm and all-farm environment. These practices must also efficiently manage non-renewable resources like land and incorporate biological cycles and processes, all while being economically viable for the farmer and improving the lives of the farmer and society as a whole.

What was the impact of Sri Lanka's ban on synthetic fertilizers and crop protection products in 2021?

The ban on synthetic fertilizers and crop protection products in Sri Lanka led to catastrophic declines in harvests across two cycles, reducing the rice harvest by 40 percent and the corn harvest by a similar amount. This resulted in a food and economic crisis, putting growers out of business and causing political upheaval. The impacts are still being felt, with a year-over-year food inflation rate of 94 percent as of August 2022.

How does the speaker describe the role of agriculture in the United States' food supply and global food security?

The speaker emphasizes that U.S. farmers and ranchers produce an abundant, high-quality, and relatively affordable supply of food, which is critical not only for the U.S. population but also for supplying the needs of the rest of the world. The U.S. has an efficient system for distributing annual harvested crops globally, making it an essential part of the global food supply.

What is the projected growth of the world population by 2050, and how does this impact agricultural production?

The world population is expected to grow by 28 percent, reaching 10 billion people by 2050. This growth necessitates agricultural advancement and technology to meet the needs of the expanding population without putting more land that is currently in natural ecosystems into land production.

What is the role of soil fertility management in sustainable agricultural practices?

Soil fertility management is critical to maintaining non-renewable resources like land. Sustainable agricultural practices dictate a holistic approach that includes cover crops, manure, and synthetic fertilizers to manage soil fertility and ensure the land remains productive.

How does the speaker view the importance of agricultural technology advancements in managing land as a non-renewable resource?

The speaker views agricultural technology advancements as absolutely critical in managing land. These advancements allow for innovations that integrate information to drive harvest outcomes, enabling farmers to make better decisions and increase productivity while minimizing off-site movement of nutrients.

What is the speaker's stance on the use of synthetic fertilizers and crop protection products in sustainable agriculture?

The speaker supports the use of synthetic fertilizers and crop protection products as part of sustainable agricultural practices when used according to best management practices. They argue that these tools have been critical in driving farm productivity gains and are essential for meeting the needs of a growing population.

How do sustainable agricultural practices address the management of weeds in crop production?

Sustainable agricultural practices take a holistic approach to managing weeds, which includes the use of herbicides as part of an integrated system. This approach allows growers to use conservation tillage practices that foster soil health while managing weeds effectively.

What is the connection between agricultural production practices and the United Nations' 17 sustainable development goals?

Agricultural production practices touch almost all 17 of the United Nations' sustainable development goals, providing a framework for conversations around metrics and progress towards these goals. This helps foster transparency and understanding of how food is sustainably produced and supports the industry's contribution to global sustainability.
