How does agriculture positively affect the environment?
We plant cover crops to take better care of our soil. Cover crops hold nutrients in the soil, help retain moisture in the soil, reduce runoff, reduce the need for tillage and store more carbon in the soil. We live in hilly terrain and have witnessed the value of cover crops in helping us improve soil and water quality.
What are the effects of modern agriculture on food resources?
The top fertile soil of the farmland is removed due to the excessive water supply. This leads to the loss of nutrient-rich soil that hampered productivity. It also causes global warming because the silt of water bodies induces the release of soil carbon from the particulate organic material.

What is deforestation caused by?
Farmers often cause deforestation by clearing land for their crops. Most of the deforestation happens because of slash-and-burn farming.
Why is irrigation important?
Irrigation, the process of applying controlled amounts of water to plants, can also create various problems for the environment. It can lead to the depletion of underground layers of water that are crucial for the environment.

Some Local and Regional Changes of Modern Agricultural Practices: 1. It leads to soil erosion. 2. It results into increase in sedimentation towards downstream side of river. ADVERTISEMENTS: 3. Alteration in the fertility of soil. 4.
What are the disadvantages of using pesticides?
Following are its disadvantages: 1. Species which are not targeted are also killed or injured. 2. After sometime the pest develop resistance against the pesticides. ADVERTISEMENTS: 3.
What are the disadvantages of artificial fertilizers?
Disadvantages of Use of Artificial Chemical Fertilizers: 1. Increase in water borne diseases due to contamination of surface and ground water resources . 2. Loss of natural fertility of the soil. 3. Loss of organic matter from the soil. ADVERTISEMENTS: 4.
Why is it so hard to meet the demand for accelerated agricultural productivity?
The reasons for this have to do with ecological factors. Global climate change is destabilizing many of the natural processes that make modern agriculture possible.
What is the effect of nitrogen on soil?
In addition, fertilizer application in soil leads to the formation and release of nitrous oxide, one of the most harmful greenhouse gases.
How does irrigation affect water?
Irrigation causes increases in water evaporation, impacting both surface air temperature and pressure as well as atmospheric moisture conditions . Recent studies have confirmed that cropland irrigation can influence rainfall patterns not only over the irrigated area but even thousands of miles away.
What is irrigation related to?
Irrigation has also been connected to the erosion of coastlines and other kinds of long-term ecological and habitat destruction. A huge amount of agricultural territory is used primarily as pasture for cattle and other livestock.
What causes algae blooms in China?
Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive.
What are the consequences of irrigation?
One of the most obvious consequences is the depletion of aquifers, river systems, and downstream ground water. However, there are a number of other negative effects related to irrigation.
How do cattle damage soil?
Cattle and other large grazing animals can even damage soil by trampling on it. Bare, compacted land can bring about soil erosion and destruction of topsoil quality due to the runoff of nutrients. These and other impacts can destabilize a variety of fragile ecosystems and wildlife habitats. Chemical Fertilizer.
How does urban agriculture help the environment?
Urban agriculture on a small scale can help to localize food production, reducing the overall environmental footprint of our modern food systems. Benefits include lower greenhouse gas emissions, minimal transportation requirements, and reduced energy use for food production.
What are some examples of agricultural systems?
For example, open meadow habitats are important for species like waterfowl, amphibians and for pollinators. Some species even increase in number due to agricultural activities.
How does rotational grazing affect biodiversity?
Through grazing for a limited time period in one area, biodiversity of native plants increases because grasses have time to regrow equally without one species taking over and becoming invasive.
Why do grasslands exist?
Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture. In Romania, however, they still exist because of the traditional (low-impact) way of farming and seasonal grazing of livestock by shepherds.
Why is maintaining land important?
Maintaining land for agricultural use can also prevent that land from being developed and urbanized, in areas where native species have difficulty finding original habitat. The United States Department of Agriculture Farm Service Agency (FSA) created seven voluntary land conservation programs for this purpose.
How do plants and trees help the aquifer?
Plants and trees in agricultural systems help to retain and add water to underground aquifers. This process is most effective when the crops being grown are perennials that continue to grow every year and have deep, well-established root systems.
What is the most dominant land use on the planet?
As time passed, agriculture became the most dominant land use on the planet, feeding a booming population and transforming natural habitats of many species. Whether the outcome of this change delivers negative or positive consequences depends largely on our approach. You may think it sounds counter-intuitive, but sustainable management …
How is soil fertility maintained?
In traditional methods, soil fertility and quality is maintained through recycling of nutrients by a variety of plant and animal species and several other natural contributors. But in intensive agriculture, fertility of the soil is maintained by incorporating fertilizers frequently. If the nutrients and other minerals which were lost due to continuous cultivation and excess runoff were not replaced properly by fertilization, poor soil quality is resulted.
Why is the use of more inputs important?
Use of more inputs give higher yields thus increasing the overall production. These higher yields will be adequate to meet the growing food and fuel demands of the increasing population. Hunger and malnourishment incidences may be alleviated.
How does mechanisation affect agriculture?
The mechanisation of agriculture require various energy resources such as diesel, electricity, petrol etc. Moreover, higher use of fertilizers as well, has negative impact on the ecology of the country by air pollution.

What are the main reasons for decline in forest wealth?
The main reasons for decline in forest wealth are: 1. Increase in population resulting in more demand for fuel wood and timber. 3. Indiscriminate siting of development projects.
Why has the forest area in the recent past not changed much?
5. The forest area in the recent past has not changed much because its diversion for non-forestry purposes has been more or less compensated by afforestation. “The annual withdrawal of fuel wood is estimated at 235 million cubic meters against a sustainable capacity of about 48 million cubic meters.
What is the pest problem?
Pest Problem: With the shift in crop pattern, increase in area under irrigation and higher cropping intensity, the pest problem has become very severe. The seriousness of pests has further increased by way of indiscriminate and increased use of pesticides.
