How does agriculture cause population growth


The expansion of agricultural land since Malthus’s time, and the enormous increases in crop yields resulting from the application of science to agricultural technology, were what allowed the population to grow to 6 billion.

Despite rapid population growth, food production per capita has increased due to green revolution and agricultural intensification in several counties of the world. Several research findings substantiate the theory of agricultural intensification taking into account population as a driver of development.


How does population growth affect agriculture?

Increasing numbers of people often drive up demand for food, which typically results in additional use of arable land and water. The Food and Agriculture Organization projects that by 2050, population and economic growth will result in a doubling of demand for food globally.

What affect did agriculture have on population?

The short and simple answer is that they have a positive impact on population growth initially and then a negative or neutral impact thereafter. Historic agricultural societies had an incentive to produce many children. With agriculture, labor was everything. More labor, more food.

How did improved agriculture conribute to population growth?

Does agriculture contribute to economic growth?

Now, as we can see that agriculture has a big contribution, its growth will stimulate the overall growth of the economy. Now, this has been argued widely that a country prospers when its secondary or industry sector outnumbers other sectors. Most developed nations has witnessed a massive industrial revolution in its history.


Impact of Population Growth on Agriculture

Impact of population growth on agriculture is an important topic to discuss .On a population growth of 2%, the population would grow by about 350 million people. This population increase will have an impact on agriculture and will require more food production to meet demand. In order to do this, there are three things that must happen:

Positive Impact Of Population Growth On Agriculture

As population growth continues, there will inevitably be an increased demand for agricultural products. This is because food production must keep up with the world’s growing hunger and as more people move into urban areas where they no longer need to farm their own land.

Adverse Impact Of Population Growth On Agriculture

Population growth in third world countries is also putting a strain on the agricultural industry. Though there are some benefits to population growth, such as increased demand for food products and more tax revenue generated from higher populations of citizens needed to fill jobs, it’s not all rainbows and sunshine.’

Impact Of Population Growth On Crop Production

Crop production is a critical factor in the growth of population size. The world’s crop production will probably need to double, triple or quadruple by 2050 to meet our food needs and sustain current standards for living conditions.

Impact Of Population Growth On Farmers

The increased population of the world is causing a lot of strain on farmers. There are many issues, including more people to feed and less land for agricultural production – but there’s also an increase in demand for food created by all these extra mouths to feed.

Which state has the highest population growth?

Journalist Alexandra Tempus writes, “This region is also experiencing explosive population growth—with Idaho, Nevada, Arizona and Utah topping the list of states with the highest percentage increase in residents from 2018 to 2019, according to the U.S. Census Bureau.”.

What are the impacts of the Southwest and West?

Areas in the Southwest and West are seeing increases in population and experiencing the environmental impacts of this growth.

Is suboptimal farmland bad for the environment?

And suboptimal farmland requires more water, more transportation, more energy, more fertilizers, and more pesticid es to be productive, all of which are bad for the environment.”. The path we are on is unsustainable and our expectations of what our land and water supply can provide as our population continues to increase are inflated and unrealistic.

What does population growth mean?

Population growth means an increased demand for homes and services. That kicks up the price for land, meaning farmers can’t afford to buy it. But sometimes farmers can’t afford not to sell their land. It depends what side of the fence you’re on when it comes to skyrocketing land values.

Why do we need private land?

We need private land and our farmers and ranchers to pursue modern agriculture. That land and the people who work it grow our food, conserve water and preserve wildlife habitat.

Is Texas a rural state?

Texas is still a rural state, but it’s growing more urban every year. That’s both an opportunity and a challenge for rural Texas. It’s a chance for farmers to connect with consumers like you and me, but it also means a loss of our state’s working lands and natural resources.

Can farmers and ranchers stay on land?

But farmers and ranchers can stay on the land and keep it in production for future generations. Land trusts and conservation easements with financial incentives offer farmers and ranchers a way to do so. Texas is still a rural state, but it’s growing more urban every year.

How does Ethiopia’s economy affect agriculture?

Agriculture is the mainstay of Ethiopian economy. The interaction between population and agriculture is complex. Intense debates and widespread discourse have been continued over several decades on population growth against agriculture development. 26 For the past decades, agricultural growth has been achieved partly through an expansion of farmlands. 50 Alemayehu et al., 13 also reported that crop production has increased due to area expansion although little has been contributed by agricultural inputs. Agricultural intensification and extensification are the two major strategies to raise agricultural output in general and crop yields in particular. 36, 51 As farmland increases, pressure on natural vegetation and communal grazing land also increases. Between the 1980s and the mid of 1990s, crop outputs were not exceed 10 million metric tons. To date, the yield has grown with increasing trend to more than 28 million metric tons. However, the growth of crop production is extremely uneven due to shocks, mainly exposed to spatial and temporal rainfall fluctuations. As shown in ( Figure 5 ), during severe drought such as 1984/85 is an evident for crop failure that affected production negatively whereas good weather conditions in some years resulted in bumper harvests. 52

What was the downward trend in agriculture in the 1950s?

Agriculture showed a downward trend from 4.6% in the 1950s to 3.8% and 1.9% in 1960-1965 and 1966-1973, respectively. 13 One of the main causes for the irregular pattern of agricultural growth is erratic nature of rainfall distribution.

What is the temporal dimension of population changes in terms of size and structure?

The temporal dimension of population changes in terms of size and structure, and spatial distribution of population due to births, deaths, migration, and settlement patterns refers to demographic change.

What is the argument between population and subsistence?

In the 18 th century, the speculation of Malthus has made everyone to believe the negative impact of population on development. 26 The central tenet of Malthus is “the growth of human population always tends to outstrip the productive capabilities of land resources.” He further stated ‘the influence of population is indefinitely greater than the control of the earth to produce subsistence for man’. 27 According to this theory, the arithmetic increase of subsistence could not feed the exponential growth of population. This dismal hypothesis has strengthened the theory, as human number grows food supply would be insufficient to feed the emerging people so that population pushed back below the carrying capacity of agricultural systems. 28 The debate on ‘limits to growth’ in relation to population-production nexus is a never-ending discourse. The natural and virtual inequality between population and production has multifaceted links. Adjustments and adaptations towards increasing population and land scarcity were initially possible through land extensification. 6 As opportunities for land expansion disappeared, agriculture has encroached into fragile ecosystems, often without the necessary resource amendments and led to soil degradation, deforestation, and loss of biodiversity. Consequently, Malthus suggested positive and preventive checks to balance the rising population with the existing subsistence. The positive checks include increase of mortality as a result of disease, famine, malnutrition and war while preventive checks are attributable to reducing fertility via delay marriage, abstain, and others. 28 On the word of classical economists, population is a dependent variable determined by preceding changes in agricultural productivity.

How much will the population of Ethiopia grow in 2025?

Consistent with this projection, the size of population in Ethiopia is estimated to be 188.4 and 200 million in the mid of 2050 and the 2060s, respectively. 1, 42 Hence, the estimate of Equation 3 is in agreement with the UN projection. The growth rate of population can be also calculated exponentially. 43

What are the challenges of Ethiopia?

3 Ethiopia is vulnerable to the twin threats of natural resource degradation and poverty owing to high population growth, dependent on rain fed agriculture, and negative impacts of climate changes. 4 Although anthropogenic and natural shocks resulted in adverse effects on food production, the government has made considerable efforts to produce adequate food for the growing population. As population rises, demand for food, energy and income increases. 5 Increasing population coupled with land degradation aggravates challenges of crop production. 6 Overpopulation resulted in land resource scarcity, fragmentation of farm plots , and ecological degradation such as increasing emissions, soil erosion, deforestation, and the overuse of natural resources. 7 –9 Producing adequate food for a rapidly growing population is a prime challenge for development. 10 Despite economic development improved in Ethiopia, 11, 12 the country has suffered with multifaceted challenges including land scarcity, malnutrition, recurrent drought and lack of agricultural technologies. 13 –15 The existing agricultural land is unable to feed the growing population and thus many Ethiopians remain trapped in vicious circle of poverty, disease and hunger. 7 Rising in food prices, unemployment, lack of pasture for livestock, and intensive removal of natural vegetation aggravates food shortages. Further land redistribution is not anticipated in the near future, because landholdings are already small and subjected to more divisions and fragmentations. Parents redistribute their land to their children when the children establish their own family 16 and have an impact on food shortages and household incomes. 17 consequently, arable land per capita declines while land degradation increases through overuse of land resources. Lands access to irrigation schemes, adjacent to urban centres, access to roads and other basic services have high rental values. 18 Population pressure is the most fundamental driving force for land conversions. 19, 20 Even though rural development policies adopted intensification and commercialization strategies, land expansions overshadow intensification. In line with agricultural extensification, pasturelands and the natural vegetation are converted to farmlands and commercial investments in some parts of Ethiopia. 21 On the other hand, the current regime has started to tailor fertilizer distribution based on soil maps so that farmers apply a custom-based fertilizer to mitigate the depletion of soil nutrients based on site-specific soil amendments. This type of agricultural intensification is implemented by means of internally adopted and externally imported technologies. Despite apparent yield improvements has been reported, evidences on the adoption of new technologies particularly animal breeds and crop varieties are not overwhelming. 22 –25 This paper presents agricultural implications of population dynamics based on the current evidences of knowledge on agriculture and population. The review helps to understand the link between agricultural growth and population dynamics in Ethiopia. Development theories and empirical literatures are crucial evidences to conceptualize the link between agriculture and population growth.

Is agriculture growing in Ethiopia?

Agriculture in terms of crop production and population are growing though the growth trends are different as long as population is steadily growing while production is unexpectedly oscillating. Land expan sion and agricultural intensification are the two contrasted strategies put into practice in Ethiopia.

How much will agriculture increase in 2050?

The general consensus is that global agriculture production has to be increased by about 60-70 percent from the current levels to meet the increased food demand in 2050. This takes into account several factors. First, the changes in dietary habits.

What is the best way to feed the global population in 2050?

Increasing productivity is a more sustainable approach to feeding the global population in 2050.

What is the TFP in agriculture?

Part 2 of this article will discuss the Total Factor Productivity (TFP) aspect, which is the ratio of agricultural outputs (gross crop and livestock output) to inputs (land, labor, fertilizer, feed, machinery, technology, etc.). The TFP measures changes in the efficiency with which these inputs are transformed into outputs. Today, this index accounts for the largest share of growth in global agricultural output.

How many hectares of land are there in the world in 2050?

Data source: Food and Agriculture Organization (FAO) and World Bank. The per capita arable land worldwide was 0.42 hectares in 1960. It will be 0.19 hectares in 2050. In the developing countries the area gets even smaller, per capita arable land will be reduced from 0.33 to 0.14 hectares.

What is the threat to arable land?

In the past 40 years, about one-third of the arable land has been threatened by erosion, sea water and pollutants degrading soil health and biological productivity. As the majority of fertile land is already under crop production, expansion of arable land will be limited to some regions only.

How many people will be in the world in 2050?

The current global population is 7.6 billion. It is expected to be 9.2 billion in 2050 (Fig 1). By 2050, the population in the developing countries will be roughly 8 billion. The population in the developed countries would be 1.2 billion.

How will cold chains affect food production in 2050?

It often stimulates improvements in infrastructure, including cold chains, that will allow perishable goods to be traded more widely . All these factors will exert a heavy burden on the existing arable land to produce more human food in 2050.
