Which of the following is a consequence of the green revolution?

After the green revolution, the production of cereal crops tripled with only a 30% increase in the land area cultivated. This came true all over the world, with a few exceptions. In addition, there were significant impacts on poverty reduction and lower food prices.

What is the main cause of urban migration in the United States quizlet?

The urban migration was caused by the increase of jobs in cities during the industrial revolution and the improved access to goods and services that came with changes in transportation. What caused the urban migration in the United States?

How does mining affect local populations quizlet?

Mining introduces pollution into local water supplies. c. Mining disrupts local populations of flora and fauna.

What are the damage done by crop pest?

EFFECTS OF CROP PESTS ON YIELD Pests reduce the quality of crops. Pests eat up leaves of crops, thereby reducing the photosynthetic activity of the plant. They cause injury which may predisposes crop to diseases attack. Infected seeds usually have low viability (germination) capacity.

What causes damage to the crops?

Crop damage from pathogens and pests is a worldwide problem. Agriculture crop productivity has been severely affected by various pests. The excessive use of chemicals in agriculture has led to a multitude of effects, including increased residues in plants, insect resistance, and contamination of soil, water, and air.

How do environmental factors affect agricultural production?

Environmental factors that influence the extent of crop agriculture are terrain, climate, soil properties, and soil water. It is the combination of these four factors that allow specific crops to be grown in certain areas.

How do crops affect the environment?

Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.

How do grazing animals affect forests Class 8?

Livestock grazing whether it is continuos or rotating by too many animals on the land area or forest can cause deforestation where the exposure of the topmost layer of the soil would exposes the lower layer and gradually the fertile land converted into deserts and the water holding capacity of the soil will also …

The green revolution brought many health challenges in Punjab's communities due to intensive and indiscriminate use of chemical fertilizers and pesticides, desertification, waterlogging and salinity, micronutrient s deficiency, and water scarcity.

What are the impact and consequences of climate change on the agriculture sector?

Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.

What are the environmental problems caused by the green revolution?

Loss of soil fertility, erosion of soil, soil toxicity, diminishing water resources, pollution of underground water, salinity of underground water, increased incidence of human and livestock diseases and global warming are some of the negative impacts of over adoption of agricultural technologies by the farmers to make …

What was one unintended consequence of the green revolution?

Unintended consequences in water use, soil degradation, and chemical runoff have had serious environmental impacts beyond the areas cultivated (59). The slowdown in yield growth that has been observed since the mid-1980s can be attributed, in part, to the above degradation of the agricultural resource base.

What are some consequences of urban sprawl?

Urban sprawl has significant environmental, economic and social consequences. It leads to higher emissions from road transport and loss of open space and environmental amenities. It also increases the cost of providing key public services, exerting pressure on local public finance.

Why do rural dwellers migrate to urban areas quizlet?

What are the major losses caused by pests in agricultural crops?

Among crops, the total global potential loss due to pests varied from about 50% in wheat to more than 80% in cotton production. The responses are estimated as losses of 26–29% for soybean, wheat and cotton, and 31, 37 and 40% for maize, rice and potatoes, respectively.

Who causes the most damage to crops?

Drought. Drought has been established as the single greatest culprit of agricultural production loss. Over 34 percent of crop and livestock production loss in LDCs and LMICs is traced to drought, costing the sector USD 37 billion overall.

What are the effects of pest on crops?

Heavy attack by pests may result in total crop failure. Infected seeds, crops, and vegetables have low market value. Pests reduce the quality of crops. Pests eat up leaves of crops, thereby reducing the photosynthetic activity of the plant.

What are environmental factors affecting crop growth?

Environmental factors that affect plant growth include light, temperature, water, humidity and nutrition. It's important to understand how these factors affect plant growth and development.

How does the environment affect crop yields?

Higher levels of carbon dioxide in the atmosphere have a positive effect on photosynthesis and water retention, increasing crop yields, though often at a cost to nutrition. This effect happens more so for wheat than maize, which is more accurately captured in the current generation of models.

What are the environmental risks caused by GMOs?

A major environmental concern associated with GM crops is their potential to create new weeds through out-crossing with wild relatives, or simply by persisting in the wild themselves. The potential for the above to happen is assessed prior to introduction, and is monitored after the crop is planted as well.
