Midlatitude climates tend to support similar agricultural crops and practices, such as wheat farming in the United States and China. Agricultural crops are successful only in midlatitude climates, where any crop can be grown.
What is agriculture AP Human Geography?
Agriculture: The raising of animals or the growing of crops on tended land to obtain food for primary consumption by a farmer’s family or for sale off the farm.
What is the pattern of agricultural?
Cropping pattern refers to the proportion of land under cultivation of different crops at different points of time. This indicates the time and arrangement of crops in a particular land area. Any change in the cropping pattern would cause: change in the proportion of land under different crops.
What is agriculture systems?
An agricultural system, or agro-ecosystem, is a collection of components that has as its overall purpose the production of crops and raising livestock to produce food, fiber, and energy from the Earth’s natural resources.
What is agriculture and where did agriculture begin?
Agricultural communities developed approximately 10,000 years ago when humans began to domesticate plants and animals. By establishing domesticity, families and larger groups were able to build communities and transition from a nomadic hunter-gatherer lifestyle dependent on foraging and hunting for survival.
How does climate influence agriculture?
Climate change can affect agriculture in a variety of ways. Beyond a certain range of temperatures, warming tends to reduce yields because crops speed through their develop- ment, producing less grain in the process. And higher tem- peratures also interfere with the ability of plants to get and use moisture.
What is climate change and agriculture?
On farms, climate change is reducing crop yields, the nutritional quality of major cereals, and lowering livestock productivity. Substantial investments in adaptation will be required to maintain current yields and to achieve production and food quality increases to meet demand. The problem also works in reverse.
What are the climatic factors affecting agriculture?

What are the changes in precipitation patterns?
Changing precipitation patterns. Rainfall patterns have already begun shifting across the country, and such changes are expected to intensify over the coming years. This is likely to mean more intense periods of heavy rain and longer dry periods, even within the same regions.
Why are industrial farms so expensive?
The industrial farm’s heavy reliance on fertilizers and pesticides may become even more costly to struggling farmers as climate impacts accelerate soil erosion and increase pest problems. Heavy use of such chemicals will also increase the pollution burden faced by downstream communities as flooding increases.

A family surveys their flooded farm and corn fields in Wever, Iowa, 2012. Projected impact of climate change on yields of corn, wheat, soybeans and cotton by the years 2080-2099.
How does industrial agriculture affect the ecosystem?
Industrial agriculture treats the farm as a crop factory rather than a managed ecosystem, with minimal biodiversity over wide areas of land. This lack of diversity in farming operations exposes farmers to greater risk and amplifies climate impacts such as changes in crop viability and encroaching pests. Intensive inputs.
Is agroecology underfunded?
With climate change, farmers need science more than ever, yet public funding for research that can help them cope has been in short supply. Agroecology research—which produces the kind of long-term, literally root-deep solutions that can help farms stay viable for generations— has been particularly underfunded.

Is agriculture changing climate?
Agriculture in a Changing Climate. Changes in climate and extreme weather have already occurred and are increasing challenges for agriculture nationally and globally. Many of the impacts are expected to continue or intensify in the future.
How does rainfall affect food production?
So how are these predicted changes in rainfall patterns going to affect food production? An important aspect to be understood regarding the relationship between rainfall and agriculture is that rainfall is the major factor in the growth and production of food crops both at the germination and fruit development stage. But with a change in the world’s climate, temperatures will rise and rainfall will increase in some places. In other places, rainfall will decrease. Other than the effect of high and low rainfall on cropping patterns, it is predicted that phenomena such as coastal flooding will reduce the amount of land available for agriculture. Farmers are already finding it difficult to cope with these environmental changes, as almost all crops are season-dependent and rainfall-dependent. Temperature and rainfall changes induced by climate change are likely to further react with other parameters of plant growth like atmospheric gases, fertilizers, insects, plant pathogens, weeds, and the soil’s organic matter. This again is expected to produce unanticipated responses.
What are the factors that affect plant growth?
Temperature and rainfall changes induced by climate change are likely to further react with other parameters of plant growth like atmospheric gases, fertilizers, insects, plant pathogens, weeds, and the soil’s organic matter. This again is expected to produce unanticipated responses.

What crop was cut in 2016?
In India too, following a poor monsoon, the area of wheat crop was cut. However, its effect is much less than in Southern Africa because India holds enormous volumes of wheat and rice stocks.
Why do farmers in the Philippines spread their unhusked grains on concrete streets to dry in the sun?
Many farmers in the Philippines lack post-harvest storage and drying facilities and spread their unhusked grains on concrete streets to dry in the sun. Due to this the grain was of poorer quality and fetched lower prices . To add to it, the damage and excess rain made it impossible for them to plant the next crop.
Is low rainfall a problem?
Rainfall, as we know, is an uncontrollable phenomenon. Managing the problem of low rainfall, however, is nearly possible through irrigation, but only if dealt with efficiently and without degradation to the water table, by ensuring ground water recharge practices.

Farmers are already finding it difficult to cope with these environmental changes, as almost all crops are season-dependent …
What is agriculture?
Agriculture is a highly complex system that is tightly integrated with local-to-global food systems and interlinked with rural communities that both rely on agricultural production for economic viability and support agricultural labor, input, and market requirements.
What are the threats to sustainable crop production?
Sustainable crop production is threatened by excessive runoff, leaching, and flooding, which results in soil erosion, degraded water quality in lakes and streams, and damage to rural community infrastructure.
What is the most productive farm belt in the world?
The Ogallala Aquifer region (OAR) is one of the most productive farm belts in the world. Irrigated agriculture uses more than 95% of the groundwater extracted from the Ogallala Aquifer, and the economy of the region depends almost entirely on irrigated agriculture. Overlying states produce one-fifth of the Nation’s wheat, corn, and cotton, and the southern half of the region accounts for more than one-third of the beef cattle production. 152 In 2007, the market value of agricultural products from this region was about $35 billon, which accounted for 11.6% of the total market value of agricultural products in the United States. 153
