Although with this approach, one of the biggest disadvantages to sustainable agriculture is that you are unable to grow as many crops at a single time considering a more sustainable approach typically leads to fewer crops in one plot so plants don’t leach nutrients out of the soil.

Farming activity means the cultivation of farmland for the production of crops, fruits, vegetables, ornamental and flowering plants, and the utilization of farmland for the production of dairy, livestock, poultry, and all other forms of agricultural products having a domestic or foreign market.

Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.

The main disadvantage is the limited use of land, which makes it difficult to produce large quantities of food. Therefore mass production is not possible. Since the use of machines is minimal or eliminated, it takes more time and people to successfully produce plants, which slows down the production.

Sustainable agriculture also benefits the environment by maintaining soil quality, reducing soil degradation and erosion, and saving water. In addition to these benefits, sustainable agriculture also increases biodiversity of the area by providing a variety of organisms with healthy and natural environments to live in.

Over decades of science and practice, several key sustainable farming practices have emerged—for example:

• Rotating crops and embracing diversity.
• Planting cover crops.
• Reducing or eliminating tillage.
• Applying integrated pest management (IPM).
• Integrating livestock and crops.
• Adopting agroforestry practices.

A very good example of recycling in sustainable farming would be crop waste or animal manure. The same can be transformed into fertilizers that can help enrich the soil. Collection of rainwater via channeling and then its utilization for irrigation is also a good example of sustainable farming practices.

10 Sustainable Agriculture Methods and Farming Practices

• Hydroponics and Aquaponics.
• Urban agriculture.
• Agroforestry and food forests.
• Polycultures and crop rotation.
• Heirloom and older varieties.
• Natural animal raising.
• Natural pest management.
• Mulching and manual weed control.

A food system’s sustainability is influenced by natural and human factors. These factors interact with each other within a food system. For example, the availability of water and land for food production is influenced by human actions, while human choices are influenced by environmental conditions.

Food System Basics Production, processing, distribution, and consumption – food systems require many steps, each with a variety of inputs and outputs.

Biological determinants such as hunger, appetite, and taste. Economic determinants such as cost, income, availability. Physical determinants such as access, education, skills (e.g. cooking) and time. Social determinants such as culture, family, peers and meal patterns.

APHA defines a sustainable food system as one that provides healthy food to meet current food needs while maintaining healthy ecosystems that can also provide food for generations to come with minimal negative impact to the environment. The right to food is a fundamental human right.
