Ancient agricultural techniques are being almost completely replaced in many places across the globe by modern, mechanized agriculture. Indigenous agricultural knowledge, such as that used in permaculture, has been devalued and undermined with the implementation of monocropping and Green Revolution technologies. Modern farming is experiencing experimentation with implementing modern technologies into agriculture
Traditional agriculture relies more on the use of conventional, homemade remedies for the protection against pests and insects. Traditionally, farmers used various methods to keep crops safe from pests and diseases.
Despite the effects that traditional methods have had on agricultural soils, not all traditional farms have reduced biodiversity. Compared with sustainable agriculture, conventional crops are woefully inefficient in maintaining the integrity of farmscapes. In comparisons between sustainable farming and conventional agriculture, organic methods have been shown to fare far better on many indicators. Even if conventional systems yield higher harvests than those in sustainability, growing crops in an organic manner is the more energy-efficient approach.
Sustainable/organic agriculture is designed to produce an array of crops, using no synthetic chemicals or fertilizers, and at the same time, improve the composition of soils and foster biodiversity. Conventional systems may enhance soil quality through practices such as no-till agriculture, agroforestry, and integrated pest management, but sustainable farming is the most efficient form of food production for maintaining soil conditions. Conventional agriculture is threatening the future of food production through reduced biodiversity, as well as contributing to the degradation of the environment and to climate change that lowers crop yields.
As current industrial agricultural practices continue to exhaust the nutrients in soils, and as chemical applications degrade the life-giving organic matter, regenerative agricultural practices are no longer the norm. Industrialization in agriculture has increased farming efficiency, but has reduced the quality of life of many farmers — both those forced from their fields and the many that still farm. In many developing countries, independent farmers cannot afford new technologies, and large corporations have taken over farming.
New precision-agricultural companies are developing technologies that enable farmers to maximize crop production while controlling each and every variable on crop farms, such as moisture levels, pest pressures, soil conditions, and microclimates. By providing more precise techniques to plant and cultivate crops, precision agriculture allows farmers to improve efficiency and control costs. Precision farming allows farmers to have greater precision and control over their crops and livestock. Labor is also significantly reduced through the use of robots for harvesting, sowing, and logistics, solving a problem that farms are facing due to current labour shortages in modern agriculture.
While the use of drones is quite new, there is a growing amount of mainstream farming companies incorporating automation in farm operations in their processes. Major technological innovations in agricultural technologies have focused on areas like vertical farming in enclosed spaces, automation and robotics, animal science, current greenhouse practices, precision farming and AI, and blockchain. Modern farming uses advanced technologies, is less labor-intensive compared to traditional agriculture, and has higher production quantities as it is focused on maximising yields and maintaining a constant quality. Traditional farming is still the predominant agricultural food production practice, used today by half the worlds population.
Traditional agriculture can be defined as the original style of food production and farming, which involves the intensive use of indigenous knowledge, land usage, traditional tools, natural resources, organic fertilizer, and cultural beliefs of the farmer. Agroforestry involves the intentional planting and maintenance of trees in the same area as the cropping fields. Agroforestry, intercropping, crop rotation, cover crops, conventional organic composting, and integrated crop-animal agriculture are important traditional farming practices.
Although crop-based, integrated crop-animal agriculture is the basis for Asian small-scale farming (Devendra and Thomas 2002b). Crop-animal integrated agriculture is a widely accepted practice among small-scale farmers in Asia (Devendra and Thomas 2002a ).
In practice, permaculture farms are organic, low-input, and biologically diverse, using techniques such as tree intercropping, planting perennials, water harvesting, and resource recirculation. One example among many in the practice of sustainable farming that stresses both economic benefits and ecological health is conservation agriculture. Modern farming practices stress output, capital gains, intensity of inputs, and consistency in yields.
Farmers are also using agroecology to enhance soil fertility, adapt to climate change, and lower the input costs of farms. According to UN Special Rapporteur on the Right to Food, small-scale farmers in Africa used agroecology to more than double their yields in three to 10 years after adoption. Agroecology, an agricultural approach mimicking natural ecosystems, is an alternative approach that can yield more food using fewer resources.
With changes over 50 years, farmers are now able to produce more food and fiber in fewer acres, with less nutrient input. Farmers today continue to produce food needed for humans and livestock, as well as other resources, as they have done in the past, but with new technologies and innovations. The growing sustainability agriculture movement, coupled with concerns over global warming, has led to renewed interest in the processes and struggles of the original inventors and innovators of agriculture, about 10,000-12,000.
New techniques are continually being developed using this traditional knowledge, with a number of benefits to be seen, not just to farmers, but to the environment and to food security. Ancient techniques in agriculture and construction are being proven to be in some cases more efficient than their modern counterparts. In California, some farmers are returning to dry-land farming, a technique whereby they trap moisture in the soil in rainy seasons, sustaining crops during dry seasons without having to turn to costly, and increasingly untenable, irrigation. While hydroponics and aquaponics are energy-intensive — mostly due to the need for continuous artificial light — they are effective and produce higher yields of healthier crops.
These products, and therefore farming methods used, can differ between parts of the world. Agricultural methods generally differ greatly across the globe, depending on climate, land area, traditions, and available technologies.
