Global population growth means that food production needs to increase by 70% by 2050 , placing pressure on food quality standards. The Food and Agricultural Organization of the United Nations (FAO) forecasts that global food production will need to increase by 70% if the population reaches 9.1bn by 2050.
How does population growth affect food production?
Food production depends on croplands and water supply , which are under strain as human populations increase . Pressure on limited land resources, driven in part by population growth , can mean expansion of cropland. This often involves destruction of vital forest resources or overexploitation of arable land.
What is the relationship between population and food production?
Contrary to the widely held belief that food production must be increased to feed the growing population, experimental and correlational data indicate that human population growth varies as a function of food availability .
How important is the food production in relation to population?
The relationship between a population and its food supply is a matter of prime importance . If unchecked, wrote Malthus, a population could grow geometrically, but given a limited area of cropland its food supply could grow only arithmetically, at best. ...
What is the relationship between agriculture and population growth?
As population grows, the demand for food also raises as a result the price of agricultural outputs increase . In theory, either an increase in the price of provisions would arise from an increase of population faster than the means of subsistence, or from a different distribution of the money of the society.
What is the relationship between food production and extinction?
First, before food production even begins, natural habitats and ecosystems are destroyed to clear land that will be used for agriculture. Habitat loss is one of the leading causes of population declines among wildlife species, eventually leading to extinction in many cases.
What are the three main factors that affect a population?
Three primary factors account for population change, or how much a population is increasing or decreasing. These factors are birth rate, death rate, and migration .
What are impacts of population growth?
Human population growth impacts the Earth system in a variety of ways, including: Increasing the extraction of resources from the environment . These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans.
Will food production keep up with population?
The United Nations Food and Agricultural Organization (FAO) projects that food and feed production will need to increase by 70 percent by 2050 to meet the world’s food needs. ... World agriculture has generally been successful in keeping up with world population growth over the last portion of the 20th Century.
What are the factors that caused the increase in food production?
In recent decades there has been impressive growth in food production, which has been attributed to the development of improved, disease-resistant varieties of staple crops ; the increased use of chemical fertilizers and pesticides; and the expansion of irrigated cropland.
What is importance of farming?
Answer: When farmers prioritize biodiversity on their land , it benefits the earth. Having more biodiversity results in healthier soil, less erosion, better water conservation, and healthier pollinators. This is all good news for the environment as a whole, making agriculture an important part of the cycle of life.
Why is population an issue?
Unsustainable population growth and lack of access to reproductive health care also puts pressure on human communities, exacerbating food and water shortages, reducing resilience in the face of climate change, and making it harder for the most vulnerable communities to rise out of intergenerational poverty.
What are the positive effect of population growth?
However, I believe that population growth has positive effects on societies. These include economic benefits such as expansion of tax bases and increased consumer spending at local businesses , as well as benefits derived from innovations by cultures seeking to keep up with growing populations.
What is the impact of population growth on energy?
The growth of world population in this period was responsible for 52% of the energy growth , while growth in per capita energy use was responsible for 48% (excluding causal connections between population and energy use per capita).
How does population affect farming?
Higher rural population density is associated with smaller farm sizes. Higher rural population density is also associated with greater demand for inorganic fertilizer. Maize and teff yields do not rise with population density. Farm income per hectare decreases as rural population density rises.
What are five environmental effects of food production?

- Environmental Contaminants & Pollutants. ...
- Depletion of Natural Resources. ...
