The concept of sustainable agriculture can be described as a system of ecological farming practices. It is based on scientific innovations through which healthy food can be produced while preserving land, air and water, and farmers’ health and rights.

The basic principles of meeting the human race’s needs, such as healthy food, improving environmental quality, preserving the natural resource base, and using non-renewable and farm resources are utilized in the most effective way so that the natural biological environment could create courses to support rural economic development.

The idea of sustainable agriculture includes the following

  • Anticipating change: farmers can recognize change; they accept it, plan for it, and know-how to adapt to it.
  • Identifying constraints and resources, and developing strategies that would improve resources and reduce and overcome constraints.

High sustainable systems aim to achieve the best use of environmental goods and services while not damaging these assets and must be locally adapted and equipped in proportion to the crop. Recent empirical evidence shows that successful sustainable agriculture initiatives and projects arise from shifts in agricultural factors of production (e.g. use of fertilizers, nitrogen-fixing substances, and pesticides). A better concept than the holistic concept is one that focuses on resource intensification, making better use of existing resources (such as land, water, biodiversity) and technology.

The main steps for sustainability are as follow

  • Incorporating biological and environmental processes such as nutrient cycling, nitrogen fixation, soil regeneration, and chemical activation
  • Reducing the use of non-renewable inputs that cause harm to the environment or the health of farmers and consumers
  • Productively utilizing farmers’ knowledge and skills, thereby improving self-reliance and replacing human capital with costly external inputs
  • Productively utilizing the collective capabilities of individuals to work together to solve common agricultural problems and natural resources, such as pests, watersheds, irrigation, etc.

Agriculture and natural resources

Sustainable agriculture can be treated as an ecosystem approach to agriculture, hence one of the primary goals is preserving key resources for future generations. It is impossible to overestimate the significance of the idea. So let’s define the most important resources like water, soil, land, energy, and air

Water

Many agricultural areas require additional irrigation due to the lack of rainfall. In order for irrigation management to be sustainable, it must simultaneously achieve the following objectives: avoiding salinization and contamination of the land, and using less water than it can be naturally replenished. This is done by using remote sensing tools. Water saturation areas can be determined quickly, which prevents crop losses and helps manage irrigation accordingly. You can obtain all necessary data about water consumption, moisture content of crops, or failure of water equipment using satellite images for example.

Soil

Intensive farming practices in recent decades have had a devastating impact on soil quality. They reduce the level of carbon in the soil, accelerate climate change, and damage soil structure, crop growth, and ecosystem functioning. To prevent further degradation, sustainable soil management techniques should include no-till agriculture, design of main lines, and windbreaks to reduce wind erosion, review the use of chemical fertilizers and protect the soil from runoff. To prevent further degradation, sustainable soil management techniques must include non-tillage agriculture, major line design, wind sources to reduce wind erosion, reconsidering the use of chemical fertilizers, and protecting the soil from water stress.

 

Another problem with organic farming is the excessive use of phosphorus inputs that lead to excessive nutrition and soil fertility depletion. The key concept of how to avoid undesirable consequences involves the use of phosphate rock, which is a natural element in some soil types, and the use of microbial vaccines such as microorganisms that dissolve phosphate. The energy reflected in multiple spectral ranges is measured in excess of visible light (infrared, heat, etc.), which can be used separately or combined to indicate the precise phenological stage of the crops to apply the appropriate amount of inputs.

Energy

Agriculture now is highly dependent on fuel and non-renewable energy sources in general. The only way to overcome this dependence is to consider the use of “smart” agricultural systems for energy and the transition to renewable energy. The concept of solar irrigation developed by Pakistani scientists is said to be the most promising initiative in this field.

Air

Almost all agricultural activities pollute the air with the dust of tillage, burning smoke, pesticide drift, and nitrous oxide emissions during the use of nitrogenous fertilizers, traffic, and harvesting.

Air quality improvement options may include: use of crop residues for soil, appropriate levels of tillage, and the installation of windbreaks

Benefits of Sustainable Agriculture

The most commonly used argument against sustainable agriculture is that it cannot “feed the world” because of soil and temperate crop management. But let us consider the benefits of this agricultural approach.

 

The devastating environmental impact of sustainable agriculture is minimal because it aims to preserve the environment and use the least damaging technologies and inputs. Sustainable farms do not use chemical pesticides, fertilizers, genetically modified seeds, or animal antibiotics, nor do they generate toxic amounts of untreated waste. All of these factors have a positive impact on public health and the process of agriculture is becoming safer for farmers and food produced is healthier.

It also enhances and supports animal welfare. Farmers are raising their animals in conditions close to normal to reduce stress, pain, disease, and cattle suffering. The social aspect of sustainable agriculture involves a reconsideration of the importance of family farms and rural communities. Besides, other strategies can help increase the level of occupation, education, and health, as well as to meet cultural and spiritual needs.
