Target 2.1: By 2030, ensure that all people, particularly the poor and those in vulnerable situations, including infants, have access to sufficient and nutritious food all year round.

The goal of this target is to adress food insecurity, which is the lack of access to sufficient, affordable, and nutritious food.

It is important as it helps improve overall health and well-being.

Malnutrition could lead to stunted growth, weakened immune systems, and other long term health issues.

Target 2.2: By 2030, end all forms of malnutrition (including stunting, wasting, and deficiencies in micronutrients) and address the nutritional needs of adolescent girls, pregnant and lactating women, and older persons.

This involves avoiding micronutrient deficiencies (like iron and vitamin A deficiencies), overnutrition (like obesity), and undernutrition (like stunting and wasting). Malnutrition results in poor health outcomes and increased susceptibility to diseases, regardless of whether it takes the form of undernutrition or overnutrition.

Target 2.3: By 2030, double the agricultural productivity and incomes of small-scale food producers, particularly women, indigenous peoples, family farmers, and pastoralists.

Small-scale farmers play a central role in ensuring food security. This target calls for improving their access to resources, technology, and markets to enhance productivity and income while reducing poverty.

Target 2.4: By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, and that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding, and other disasters.

Agriculture must become more resilient to climate change, which is increasingly affecting food systems. This includes practices that reduce environmental damage, such as sustainable farming techniques, conservation of soil and water, and minimizing chemical use.

Target 2.5: By 2020, maintain the genetic diversity of seeds, plants, and animals, and ensure access to fair and equitable sharing of benefits arising from the utilization of genetic resources.

Genetic diversity in agriculture is essential for ensuring food security in the face of changing environmental conditions. It helps maintain crop resilience, pest resistance, and high yields.

Target 2.A: Increase investment in rural infrastructure, agricultural research, and extension services, technology development, and plant and livestock gene banks to enhance agricultural productivity.

Investment in agriculture and rural infrastructure is necessary to improve food production, access to markets, and nutrition. Agricultural research and technology development can introduce more efficient and sustainable farming practices.

Target 2.B: Correct and prevent trade restrictions and distortions in world agricultural markets.

Unfair trade practices and market distortions often prevent farmers in developing countries from accessing markets or getting fair prices for their produce. This target calls for the removal of such barriers.

Target 2.C: Adopt measures that ensure the proper functioning of food commodity markets and facilitate access to food.

A stable, well-functioning food market is essential for food security. This includes ensuring that food prices remain stable and affordable and that food supply chains are not disrupted by speculations or hoarding.
