The term ‘Post Agri’ refers to techniques and resulting outputs that have been developed to assess, collect and process post-agriculture by-products that otherwise would be discarded or released into the environment

Modern agricultural practices include the efficient cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life.  Technologically enhanced agriculture methods have, in many cases, sharply increased yields while simultaneously increasing natural resource demands, causing ecological damage and negative human health effects.   Modern agriculture produces by-products; many of which are discarded or released into the environment in the form of greenhouse gases and nutrients.

The term Post Agri refers to techniques and resulting outputs that have been developed to assess, collect and process post-agriculture by-products that otherwise would be discarded or released into the environment thus helping to alleviate negative ecological pressure and human health effects.  These techniques can take post-agriculture by-products and transform them into additional food, fuel, fibers, materials and products.   By applying these technologies to transform agriculture by-products, some elements of modern agriculture can become a renewable and sustainable activities that alleviate many of its downsides.

Post Agri technologies can be applied to all of the agriculture methods outline below.

Eco-agriculture is a landscape approach to natural resource management that pursues three goals: conservation and sustainable use of biodiversity and ecosystem services, sustained agricultural production, and improved rural livelihoods.

Eco friendly agriculture describes landscapes that support both agricultural production and biodiversity conservation, working in harmony together to improve the livelihoods of rural communities.

While many rural communities have independently practiced Eco-agriculture for thousands of years, over the past century many of these landscapes have given way to segregated land use patterns, with some areas employing intensive farming practices without regard to biodiversity impacts, and other areas fenced off completely for habitat or watershed protection. A new Eco-agriculture movement is now gaining momentum to unite land managers and other stakeholders from diverse environments to find compatible ways to conserve biodiversity while also enhancing agricultural production.

Sustainable agriculture is farming in sustainable ways based on an understanding of ecosystem services, the study of relationships between organisms and their environment. It has been defined as “an integrated system of plant and animal production practices having a site-specific application that will last over the long term”, for example:

  • Satisfy human food and fiber needs
  • Enhance environmental quality and the natural resource base upon which the agricultural economy depends
  • Make the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls
  • Sustain the economic viability of farm operations
  • Enhance the quality of life for farmers and society as a whole

Conservation agriculture (CA) can be defined by a statement given by the Food and Agricultural Organization of the United Nations as “a concept for resource-saving agricultural crop production that strives to achieve acceptable profits together with high and sustained production levels while concurrently conserving the environment” (FAO 2007).

Agriculture according to the New Standard Encyclopedia is “one of the most important sectors in the economies of most nations” (New Standard 1992). At the same time conservation is the use of resources in a manner that safely maintains a resource that can be used by humans. Conservation has become critical because the global population has increased over the years and more food needs to be produced every year (New Standard 1992). Sometimes referred to as “agricultural environmental management”, conservation agriculture may be sanctioned and funded through conservation programs promulgated through agricultural legislation, such as the U.S. Farm Bill.

The term ‘Alternative agriculture ‘ as it applies to the area of agriculture can be defined as ‘A systematic approach to farming intended to reduce agricultural pollution, enhance sustainability, and improve efficiency and profitability. Overall, alternative agriculture emphasizes management practices that take advantage of natural processes (such as nutrient cycles, nitrogen fixation, and pest-predator relationships), improve the match between cropping patterns and agronomic practices on the one hand and the productive potential and physical characteristics of the land on the other, and make selective use of commercial fertilizer and pesticides to ensure production efficiency and conservation of soil, water, energy, and biological resources. Examples of alternative agricultural practices include use of crop rotation, animal and green manures, soil and water conserving tillage systems, such as no-till planting methods, integrated pest management, and use of genetically improved crops and animals. Consonant with sustainable agriculture, alternative agriculture focuses on those farming practices that go beyond traditional or conventional agriculture, though it does not exclude conventional practices that are consistent with the overall system’.

Agricultural biodiversity is a broad term that includes all components of biological diversity of relevance to food and agriculture, and all components of biological diversity that constitute the agricultural ecosystems, also named agro-ecosystems: the variety and variability of animals, plants and micro-organisms, at the genetic, species and ecosystem levels, which are necessary to sustain key functions of the agro-ecosystem, its structure and processes.

Agricultural biodiversity is the outcome of the interactions among genetic resources, the environment and the management systems and practices used by farmers. This is the result of both natural selection and human inventive developed over millennia.
