Agro-ECOLOGY and its relevance to man
The term Agroecology can be used in multiple ways, as a science, as a movement and as a practice. Broadly stated, it is the study of the role of agriculture in the world. Agroecology provides an interdisciplinary framework with which to study the activity of agriculture. In this framework, agriculture does not exist as an isolated entity, but as part of an ecology of contexts. Agroecology draws upon basic ecological principles for its conceptual framework.
Agroecologists study a variety of agroecosystems, and the field of agroecology is not associated with any one particular method of farming, whether it be organic, conventional, intensive or extensive. Furthermore, it is not defined by certain management practices, such as the use of natural enemies in place of insecticides, or polyculture in place of Monoculture.
Additionally, agroecologists do not unanimously oppose technology or inputs in agriculture but instead assess how, when, and if technology can be used in Conjunction with natural, social and human assets[2]. Agroecology proposes a context- or site-specific manner of studying agroecosystems, and as such, it recognizes that there is no universal formula or recipe for the success and maximum well-being of an agroecosystem.
After the 1970s, when agronomists saw the value of ecology and ecologists began to use the agricultural systems as study plots, studies in agroecology grew more rapidly. Gliessman describes that the innovative work of Prof. Efraim Hernandez X., who developed research based on indigenous systems of knowledge in Mexico, led to Education programs in agroecology. In 1977 Prof. Efraim Hernandez X. explained that modern agricultural systems had lost their ecological foundation when socio-economic factors became the only driving force in the food system. The acknowledgement that the socio-economic interactions are indeed one of the fundamental components of any agroecosystems came to Light in 1982, with the ARTICLE Agroecologia del Tropico Americano by Montaldo. The author argues that the socio-economic context cannot be separated from the agricultural systems when designing agricultural practices.
Relevence of agro-ecology
To arrive at a point of view about a particular way of farming, an agroecologist would first seek to understand the contexts in which the farm(s) is(are) involved. Each farm may be inserted in a unique combination of factors or contexts. Each farmer may have their own premises about the meanings of an agricultural endeavor, and these meanings might be different from those of agroecologists. Generally, farmers seek a configuration that is viable in multiple contexts, such as family, financial, technical, political, logistical, market, environmental, spiritual. Agroecologists want to understand the behavior of those who seek livelihoods from plant and animal increase, acknowledging the organization and planning that is required to run a farm.
Because organic agriculture proclaims to sustain the Health of soils, Ecosystems, and people, it has much in common with Agroecology, this does not mean that Agroecology is synonymous with organic agriculture, nor that Agroecology views Organic Farming as the ‘right’ way of farming. Also, it is important to point out that there are large differences in organic standards among countries and certifying agencies. Three of the main areas that agroecologists would look at in farms, would be: the environmental impacts, animal welfare issues, and the social aspects.
Environmental impacts caused by organic and non-organic milk production can vary significantly. For both cases, there are positive and negative environmental consequences. Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3−) and phosphates (PO4−) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic Dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-Average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.
A key component of animal welfare is freedom to perform their innate (natural) behavior, and this is stated in one of the basic principles of organic agriculture. Also, there are other aspects of animal welfare to be considered – such as freedom from hunger, thirst, discomfort, injury, fear, distress, disease and pain. Because organic standards require loose housing systems, adequate bedding, restrictions on the area of slatted floors, a minimum forage proportion in the ruminant diets, and tend to limit stocking densities both on pasture and in housing for dairy cows, they potentially promote good foot and hoof health. Some studies show lower incidence of placenta retention, milk fever, abomasums displacement and other diseases in organic than in conventional dairy herds. However, the level of infections by parasites in organically managed herds is generally higher than in conventional herds.
No-Tillage is one of the components of conservation agriculture practices and is considered more environmental friendly than complete tillage. There is a general consensus that no-till can increase soils capacity of acting as a Carbon Sink, especially when combined with cover crops. No-till can contribute to higher Soil organic matter and organic carbon content in soils, though reports of no-effects of no-tillage in organic matter and organic carbon soil contents also exist, depending on environmental and crop conditions. In addition, no-till can indirectly reduce CO2 emissions by decreasing the use of fossil fuels. Most crops can benefit from the practice of no-till, but not all crops are suitable for complete no-till agriculture. Crops that do not perform well when competing with other Plants that grow in untilled soil in their early stages can be best grown by using other conservation tillage practices, like a combination of strip-till with no-till areas. Also, crops which harvestable portion grows underground can have better results with strip-tillage,[citation needed] mainly in soils which are hard for plant roots to penetrate into deeper layers to access water and nutrients.
The benefits provided by no-tillage to predators may lead to larger predator populations, which is a good way to control pests (biological control), but also can facilitate predation of the crop itself. In corn crops, for instance, predation by caterpillars can be higher in no-till than in conventional tillage fields.
In places with rigorous winter, untilled soil can take longer to warm and dry in spring, which may delay planting to less ideal dates. Another factor to be considered is that organic residue from the prior year’s crops lying on the surface of untilled fields can provide a favorable Environment to pathogens, helping to increase the risk of transmitting diseases to the future crop. And because no-till farming provides good environment for pathogens, insects and Weeds, it can lead farmers to a more intensive use of chemicals for pest control. Other disadvantages of no-till include underground rot, low soil temperatures and high moisture.

Agroecology is a holistic approach to agriculture that considers the interactions between plants, animals, soil, water, and the environment. It seeks to develop sustainable agricultural practices that are both productive and environmentally friendly.
Agroecology is relevant to man because it provides a way to produce food that is both healthy and sustainable. Agroecological practices can help to reduce soil erosion, improve water quality, and protect Biodiversity-2/”>Biodiversity. They can also help to mitigate Climate change and improve Food Security.
Here are some of the benefits of agroecology:
- Agroecology can help to reduce soil erosion. Soil erosion is a major problem in many parts of the world. It can lead to the loss of topsoil, which is essential for plant Growth. Agroecological practices, such as cover Cropping and no-till farming, can help to reduce soil erosion.
- Agroecology can improve water quality. Agriculture is a major source of Water Pollution. Agroecological practices, such as using cover crops and compost, can help to improve water quality.
- Agroecology can protect biodiversity. Agriculture can have a negative impact on biodiversity. Agroecological practices, such as using native plants and avoiding monoculture, can help to protect biodiversity.
- Agroecology can help to mitigate Climate Change. Agriculture is a major contributor to climate change. Agroecological practices, such as using cover crops and no-till farming, can help to mitigate climate change.
- Agroecology can improve food security. Food security is a problem in many parts of the world. Agroecological practices can help to improve food security by increasing crop yields and reducing the use of pesticides and Fertilizers.
Agroecology is a promising approach to agriculture that can help to address some of the major challenges facing the world today. It is a sustainable and environmentally friendly way to produce food that can help to improve food security and protect the environment.
Here are some examples of agroecological practices:
- Cover cropping: Cover cropping is a practice that involves planting a cover crop, such as a legume or grass, between Cash Crops. Cover crops help to improve soil health, reduce erosion, and suppress weeds.
- No-till farming: No-till farming is a practice that involves planting crops without disturbing the soil. This helps to reduce soil erosion and improve water infiltration.
- Intercropping: Intercropping is a practice that involves planting two or more crops together. This helps to improve crop yields and reduce the risk of pests and diseases.
- Polyculture: Polyculture is a practice that involves planting a variety of crops together. This helps to improve crop yields and reduce the risk of pests and diseases.
- Permaculture: Permaculture is a system of agriculture that is based on the principles of ecology and sustainability. Permaculture systems are designed to be self-sufficient and resilient.
