Greenhouse gas emissions are the main contributor of climate change, and are thus an important indicator of a food system's contribution to climate change. In addition, greenhouse gases from transforming land (clearing, burning, or otherwise removing existing vegetation) for agricultural use are a large source of food system greenhouse gas emissions. Climate change is associated with increased land surface temperature, extreme weather events, rising sea levels, and other changes to the environment. These changes may impact the quality, quantity, and safety of our food supply.

Urbanization can be a challenge to the food system, as with increased proportion of people living in urban areas, food production is at risk of declining, especially on low- and middle-sized farms. Urban areas demand high penetration of food distribution and retail.

Population growth is relevant as it speaks to how fast a population is changing, what the age profile of the population is, and gives clues to the age-dependency ratio. A fast growing population also means pressure on the food system to continue increasing supply to meet the demands of a larger population.

Packaged food sales may provide an idea of the availability and demand for processed foods in a country. Packaged foods often have a longer shelf-life, fewer issues with food safety, and added convenience for people. For example, canned vegetables may enhance yearlong access in areas where local production is low or highly seasonal. On the other hand, many packaged and processed foods are energy dense and high in added sugar, salt, and fats (see ultra-processed food sales).

This indicator proxies the availability of UPFs, defined as foods made of mostly industrial ingredients and additives with minimal amounts of unprocessed foods. These additives are not naturally occurring in the food but are added in the processing phase in order to increase palatability and shelf life. Examples of UPFs include sweet and savory snacks, instant noodles, confectionery, meat substitutes, and soft drinks, among others.

Supermarkets increase people's physical and economic access to a wide variety of foods, including both fresh and processed foods. Supermarket chains typically begin with market advantages in dry and packaged foods, though eventually expand to fresh foods. Supermarkets require high standards in food quality and safety and often put in place dedicated supply chains. They bring opportunities as well as competition for local farmers and traditional retailers.

Modern grocery store retailers increase people's physical and economic access to a wide variety of foods, including both fresh and processed foods. They also create opportunity and competition for local farmers and traditional food retailers.

Final consumption expenditure provides an approximate measure of income and consumer spending power, which impacts the affordability of foods and consumer behavior.

This indicates agricultural land dynamics, which can affect food supply and environmental quality.

Embedding at least 10% of natural and seminatural vegetation is being proposed as a planetary boundary to guarantee that agricultural lands have integrity and a minimum amount of natural capital to provide ecosystem services. Attaining 10% natural vegetation is a low target that all cropland systems must fulfill.

Adults who are obese are at increased risk of diet related noncommunicable diseases and premature mortality (The Global BMI Mortality Collaboration 2016).

Women who are underweight may not be receiving the adequate amount of energy and macronutrients, placing them at greater risk for micronutrient deficiencies, osteoporosis, infection, and mortality. Women of reproductive age who are underweight may be at greater risk for adverse pregnancy outcomes if they become pregnant.

High consumption of sugary foods and beverages and processed flours and starches above the recommended amounts and proportions contributes to the development of Type II diabetes.
