  • The interaction between human population and agricultural production is complex.Intense debates have been continued on population growth against agricultural development. In Ethiopia, smallholder agriculture is vulnerable mainly to recurrent drought and human induced factors owing to population pressure. The aim of this paper is to demonstrate trends and controversies of population growth and to examine the link between population and food production in Ethiopia. This review discloses that thegrowths of population and agricultural production have increased over time. However, production growth shows oscillating trends compared to population growth. Despite the declining of mortality and fertility opens up the window of opportunity to capture the demographic dividend, rapidpopulation growth is one of the major development challenges coupled with land degradation. If this opportunity complements efficient agricultural policies and strategies, the growing population can access adequate yields for home consumption as well as household incomes. Effective population policy, improved land resource management, and integrated strategies can reduce pressure on land resource. Therefore, this review suggests that critical review on agricultural policy and strategies is one of the prospective responses to the rising population.

  • Land use land cover (LULC) changes have emerged as a pivotal driver of environmental challenges in the Northwestern mountainous belts of Pakistan. These changes are increasingly recognized for their pervasive impacts on biodiversity and ecosystem services. The conversion of pastures and rangelands into other land uses is a key facet of LULC change, posing a substantial threat to the availability of animal feed sources. This study aims to evaluate LULC changes and investigate their consequences on animal feed sources in the Upper Kurram Valley, located in the Koh-e-Safid mountain of Northwestern Pakistan. The study employs a multidisciplinary methodological approach that incorporates remotely sensed data, focus group discussions, interviews, and field observations. The study findings uncover a notable decline in rangeland (26.6%) and forest cover (28.7%) over a span of more than three decades (1987–2019). The shrinkage of rangeland has spurred an increased reliance on crop residues and fodder crops. The free grazing practices have been replaced by stall-feeding and controlled grazing methods. This declining rangeland resources has negatively affected animal husbandry, and the average number of livestock per household decreased from 32 in 1980 to 3.7 in 2019. In essence, this transition has not only impacted animal feed sources but also reshaped the livelihoods of local communities closely connected to animal husbandry.

An Expression Of Population Pressure Exerted On Agricultural Land Is (2024)


An Expression Of Population Pressure Exerted On Agricultural Land Is? ›

The correct answer is D. physiological density

physiological density
The physiological density or real population density is the number of people per unit area of arable land. A higher physiological density suggests that the available agricultural land is being used by more and may reach its output limit sooner than a country that has a lower physiological density. › wiki › Physiological_density
, which measures the number of people per unit area of arable land and thus indicates the pressure on agricultural resources.

What is the population pressure on land? ›

Population pressure, a term summarizing the stress brought about by an excessive population density and its consequences, is used both in conjunction with human overpopulation and with other animal populations that suffer from too many individuals per area (or volume in the case of aquatic organisms).

What is the agricultural population density? ›

Agricultural Population Density: The ratio of farmers (or farms) to arable land. "Agriculture" here refers solely to crops and not to domestic animals, thus in this definition arable land does not include rangeland for animal grazing.

What is land suited for agriculture called? ›

Arable land (from the Latin: arabilis, "able to be ploughed") is any land capable of being ploughed and used to grow crops.

What does a low agricultural density mean? ›

If there are more farmers than land, land will be scarce and the density of farmers working on it will be high, and agricultural production will be inefficient. Thus this question of a small amount of farmers on a large amount of land is measured as a low agricultural density.

What is an expression of population pressure exerted on agricultural land? ›

An expression of population pressure exerted on agricultural land is A. crude density.

What is pressure the population exerts on the land? ›

Population pressure is the total of all the factors, like an increase in population, which reduces the ability of a geographic area to support the inhabitants. The productivity of the land is also a factor in studying the physiological density of an area.

What is the land of agriculture? ›

Agricultural land refers to the share of land area that is arable, under permanent crops, and under permanent pastures.

What is an agricultural use of land? ›

Agricultural land is divided into two main categories: arable land – which is where we grow plants for food – and marginal land, which is land that is not suitable for growing crops for one reason or another. Arable land takes up one third of agricultural land, and is dedicated for crop production.

What is the land suitable for agriculture? ›

Soil Quality: Land Suitability for Farming

The best type of soil for planting crops is loamy soil because it has high water and nutrient retention capacity. Loamy soils are comprised of silt, clay, and sand.

Which region of the US is most populated? ›

Regionally, the South accounts for almost 40% of the American population and is the most populous part of the country.

What is the pressure on land? ›

The standard, or near-average, atmospheric pressure at sea level on the Earth is 1013.25 millibars, or about 14.7 pounds per square inch.

What does population pressure mean? ›

the force exerted by a growing population upon its environment, resulting in dispersal or reduction of the population.

How does population affect the land? ›

Additionally, as populations increase, more land is used for agricultural activities to grow crops and support livestock. This, in turn, can decrease species populations, geographic ranges, biodiversity, and alter interactions among organisms.

In what ways has the human population put pressure on the land? ›

The impact of so many humans on the environment takes two major forms: consumption of resources such as land, food, water, air, fossil fuels and minerals. waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases.
