ABSTRACT
Agriculture requires the dedication of many of our natural resources, including land, water, and energy. When the quality and quantity of our natural resources degrades as a result of unsustainable practices, it’s not only the environment that suffers–the viability of future agricultural operations is also put at risk. Sustainable agriculture is founded on the premise that our resources can be carefully managed and cultivated to make them last indefinitely.
Agriculture is perhaps the most outstanding issue and challenge for sustainability. To attain the ‘sustainable development’ goal requires urgent actions on three fronts - the ecological, the social and the economic. A growing movement has emerged during the past two decades to question

This type of agriculture tries to find a good balance between the need for food production and the preservation of the ecological system within the environment. In addition to producing food, there are several overall goals associated with sustainable agriculture, including conserving water, reducing the use of fertilizers and pesticides, and promoting biodiversity in crops grown and the ecosystem. Sustainable agriculture also focuses on maintaining economic stability of farms and helping farmers improve their techniques and quality of …show more content…
In terms of human health, crops grown through sustainable agriculture are better for people. Due to the lack of chemical pesticides and fertilizers, people are not being exposed to or consuming synthetic materials. This limits the risk of people becoming ill from exposure to these chemicals. In addition, the crops produced through sustainable agriculture can also be more nutritious because the overall crops are healthier and more natural.
Sustainable agriculture has also had positive impacts of the environment. One major benefit to the environment is that sustainable agriculture uses 30% less energy per unit of crop yield in comparison to industrialized agriculture. This reduced reliance on fossil fuels results in the release of less chemicals and pollution into the environment. 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
Agriculture—it’s something that not very many people know much about. However, it is important for us to survive. Almost everything in our everyday lives is agriculture-related, from the food you eat to the clothes you wear.
By implementing new farming techniques provided with the new technological advances in machines we can see abundant harvest in even the poorest third world countries. For example, the Green Revolution has already showed admirable progress in the northern part of India ever since it took start in 1950. By 1997, northern India increased its grain production by 37 percent. This has proven that traditional farming methods are being rendered obsolete. And because by the year 2000, there will be half the land per person in developing countries as there was in 1970, we need to apply ultra-efficient methods to sustain the growing need. Not only does the Green Revolution enhances food output, it also preserves the environment.
Food production has many challenges to address: CO2 emissions, which are projected to increase by two-thirds in the next 20 years, as the global food production increases so does the number of people going hungry, with the number of urban hungry soaring. The environmental issues are not the only ones to face; politics and economic globalization take also the big part in the food world. These days agriculture and food politics has been going through many changes but mostly under the influence of its consumers; back in the days people wanted as little as safety, variety and low costs of food. Now consumers demanding way more – greater freshness, nutritional value, less synthetic chemicals, smaller carbon footprint and less harm to animals. And that’s the time when urban agriculture emerged quite rapidly delivering locally grown and healthy food. Within the political arena, there are a few still in charge of defending the conventional food industries and commercial farms to retain the upper level. Against the hopes of nutrition activists, farm animal welfare defenders, and organic food promoters, the food and agriculture sector is moving towards greater consolidation and better sustainability. Although in social and local terms, food-growing activists know their role is under attack. Caught two words in the middle, is it possible to satisfy both?
Crop production input optimization is one of the fundamental domain of precision agriculture. It can help manage crop production more efficiently and effectively which directly relates PA with the term sustainability. Use of fertilizers can be optimized with technologies of PA which results in minimization of use of chemicals. Thus Precision agriculture helps in sustaining environment by reducing input of chemicals in natural resources.
In 2013, about 15.2% of 902 U.S. chief household said that they eat local food twice a week (“How Often”). Now, in 2014, about 20.9% out of the 902 U.S. chief household said that they eat local food twice a week (“How Often”). People should obtain their meat from locally sustainable farms instead of the supermarkets because locally raised meat is more healthier and the animals are treated humanely. People usually want meat that helps benefits their health.
No one knows the origins of agriculture. Since the beginning of recorded history, agriculture has existed. Yet not all vegetation is native to its location today. They have been diffused through many different cultures over time and had expanded greatly due to the industrial revolution. In chapter 10 titled, “Agriculture” of the book Contemporary Human Geography, written by J. Rubenstein. Rubenstein describes the expansion of the production of food from just family consumption to mass production in four steps; expand agriculture, increase agricultural activity, identify new food sources, and expand exports. One of the biggest processes happens in the second step (increase agricultural activity) known as the green revolution. The green revolution refers to scientifically engineered seeds of grain, maize, and rice that have been created and grown to adapt to many different climates rather than just temperate ones(Rubenstein, 10.7).To explain present times J. Benson describes about the different techniques used for agriculture today in the article, “Drastic changes to US agriculture policy necessary for future of food, say scientists”. As Benson explains farmers today use organic farming, grass-fed animal raising, and biodiversity growing methods to sustain a long-term agricultural which creates nutrition rich food as well as nutrition rich soil(Benson, 2011). Nutrition rich food and Nutrition rich soil is well needed. Nutrition rich soil sustains agriculture conditions. Without it, crops don't have the proper conditions to grow, which decreases the crop and requires the need for international trade to make up what is lost.
For years organic farmers and conventional farmers have feuded over which is superior. Organic farmers argue that their product is more eco-friendly because they do not use the synthetic chemicals and fertilizers conventional farmer’s use. Conventional farmers argue that their product is healthier and yields more. People tend to have stereotypes regarding the two types of farmers. Organic farmers are usually thought of as liberal, hippy, tree-huggers while conventional farmers are usually thought of as right-wing, industrialists. Obviously, some do adhere to this stereotype, but a majority of these farmers are normal, hardworking people. Although these farmers, both believe in their methods, one is no better than the other. There are advantages and disadvantages to both, but there is no true superior method of crop farming.
Also, it is our responsibility to keep the environment sustained because we are dependent on this planet. We can produce food more sustainably by using less high-input agriculture and more low-input traditional agriculture as well as organic agriculture to produce food. All of these harmful effects to the environment can be avoided by using organic agriculture where crops are grown with the use of ecologically sound and sustainable methods and without the use of synthetic pesticides, synthetic inorganic fertilizers, and genetically engineered plants or animals. Organic farming has many benefits, but it requires more labor.
A study of 362 datasets found that organic agriculture produces 80% of conventional yield with 21% standard deviation (Tomek et al. 2012). Second, organic farming requires less energy input which equates to less money spend from the farmers in addition to lowering carbon emissions. A study by the Department of Environment shows that organic agriculture uses 25 percent less than energy than their chemical counterparts, and certain crops like organic leeks and broccoli use 58 and 49 percent less, respectively (Bialis et al. 2013). Third, organic farming does not use pesticides. According to the World Health Center, 20,000 people die annually from the exposure of pesticides (Costa et al. 2014). Fourth, the methods that organic farmers use are better for the environment in the long run. And lastly, organic farming creates more jobs. A study done in United Kingdom shows 93,000 jobs could be created if Britain were to make a full scale shift to organic farming (Herro 2006). Although conventional agriculture is the primary producer for food currently, a large scale shift to organic agriculture is better suited to feed the world because organic agriculture can produce at adequate yield, requires less energy input, do not use
The source shows the reliability of biodiversity and soil quality that organic farming agriculture exploits, specifically when it has a tight grip of the economy and community that has directly affected livestock, farmers, people, and the global environment as a whole. Organic farms are sometimes difficult to maintain as the land can quite possibly lose its potential of being free from pesticides. As articulated in the source, the piece of land must also need precise qualifications which takes time and patience. This is one amongst many disadvantages a progressive movement such as organic farming must work on. The purpose is meant to enhance a genetically modified agriculture into an innately modified agriculture for a nutritious
Sustainable agriculture integrates three main goals--environmental health, economic profitability, and social and economic equity. A variety of philosophies, policies and practices have contributed to these goals. People in many different capacities, from farmers to consumers, have shared this vision and contributed to it.
Organic farming produces nutrient rich, fertile soil which nourishes the plants. Keeping chemicals off the land protects water quality and wild life.
...ocess helps reducing the loss of a large variety of species which is one of the biggest environmental concerns. Many of the vegetables travel in materials such as plastic and cardboard, by the time they arrive at the grocery store they absorb unwanted material and may lose nutrients. Growing your own vegetable garden benefit the environment by reducing the carbon emission and waste created by shipping and packaging vegetables. Environmental benefits of gardens include increasing previous surfaces and allowing for groundwater recharge, improving air quality through the addition of plants to the landscape, beautifying the environment and promoting sustainability. Of course, there are potentially negative environmental impacts associated with gardening the use of power tools uses energy, and water use is rising every year therefor we have to use wells and solar systems.
Agriculture is one of the most ancient forms of art and science that ties human development and well-being to natural resources and ecosystems. (Fritz J. Häni, 2007) Sustainable Agriculture is the production of food, fibre, plant and animal products using farming techniques that protect the environment, public health, human communities and animal welfare. (Sustainable Agriculture - The Basics, 2015) Sustainable agriculture is an integrated system of plant and animal production practices having a site – specific application that over the long term will:
To understand why is agriculture important in the world of today, then first of all we must know what agriculture is? Agriculture is the basic material production of society, the use of land for agriculture and livestock, mining plants and animals as raw materials and labor to produce mainly food and some raw materials for industry. Agriculture is a major industry, covering many disciplines: planting, breeding and processing of agricultural products; in the broadest sense, also including forestry and fisheries. Agriculture is an important economic sector in the economy of many countries, especially in the past century , when the industry has not yet developed. Since the dawn of history, agriculture has been one of the importance means of producing
