Ever since the beginning of the industrial revolution, human activities such as burning of fossil fuels such as coal, deforestation, agricultural and industrial processes have risen (United States Environmental Protection Agency Office of Policy, 1998). However, most of the greenhouse gases emanate from the burning of fossil fuels for energy. The greenhouse effect occurs when greenhouse gases behave like a blanket over the surface of the earth and trap energy. The entrapped energy causes the earth to heat up hence the reported temperature increases. Some activities that cause the emission of greenhouse gases are under the control of man and yet many more are beyond man’s jurisdiction. Numerous scientific researches reveal that human influence plays a crucial role in this quagmire (The heat is online, n.d.). Therefore, it goes without saying that the magnitude of greenhouse gases emitted is proportional to the number of people inhabiting the earth. Little can be done to reduce the population of people on earth. However, a clear understanding of the effects of the population on climate change is essential in developing a feasible blueprint for the mitigation of the undesired effects of greenhouse gases emission. This paper reviews two articles that look at the relationship between population growth and changes in climate. The Relationship between N2O and CH4 Emissions from Agriculture and Population Growth The population increase and changes in the patterns of expenditure are increasing the universal requirements for agricultural products. Only developed countries are able to meet the increased demand with the escalation of agricultural extension techniques. These techniques increase the quantities of emitted greenhouse gases (GHG) such as methane and nitrous oxide. The 1997 Kyoto protocol intends to set boundaries that reduce the emission of greenhouse gases especially in the developed countries (Annex 1). However, the developing countries (non-Annex 1) do not have targeted reduction levels. A report submitted in 2000 reveals that non-Annex 1 countries emit significantly higher amounts of GHG than Annex 1 countries. The rising population estimates that the GHG emissions in non-Annex 1 countries will increase tremendously because such countries heavily rely on agricultural production. Numerous studies focus on CO2 emission in relation to agricultural land use and yet N2O and CH4 absorbs 310 and 21 times more heat per unit weight than CO2 (Beek et al., 2010). This implies that agricultural growth is likely to be accompanied by high emissions of N2O and CH4. This paper uses ten non-Annex 1 countries and captures their key agricultural systems. Data revealing the production trends is obtained from FAOSTAT. Data from primary production (production of cereal) and secondary production (animal production) is expressed in terms of tonnes per year and livestock unit (LU) values. The EDGAR32 database and the national emission inventories of direct and indirect greenhouse gases provides data on N2O and CH4 emission. Statistical analysis reveals the relationship between demographic trends and emission of GHG, which is extrapolated to 2050. Agricultural production, as well as GHG emissions, increases in most countries. The study concludes that there ...Download file to see next pagesRead More

Population change can be studied in relation to change in the number of different species of animals and human beings. However in the biological context, population growth generally refers to any living organism, but this term mostly seem to provide greater weightage to human population in the demographical perspective. A “normal population growth” takes place when the fertility rate is higher as...

In short term, these butterflies, which have the high extinctions rate of southern population implies a light adaptation to local conditions, with little adaptation to local conditions with little evidence for flexibility in its behavior or life history strategies (Singer, 1994). However, Checkersopt butterflies have also demonstrated a remarkable ability for rapid evolution under novel conditions (Singer et al. 1993) which makes long-term response to climate change more difficult to predict. Finally, we can say that climate change may have some impact on butterflies but...

Population Growth

...Population Growth Abstract: This paper highlights the importance of population size management in a society. Some of the important measures include population growth, dependency and population composition. From the analysis of US data it is evident that over 50% of the populations are in the workforce and that in future this value is expected to decline. It is expected that the US population in 2010 will increase by 20,563 thousand and that those aged above 55 years are expected to remain constant at 21.06 % of the total population. Introduction: This paper concentrates on analysis...

In addition, Maryland population grew by 9 percent in the last decade according to new Census Bureau data (Torbati, 2010). The annual growth rate for my state, Maryland is 0.9% (State & County QuickFacts, 2011). The population of Maryland 10 years from now (in year 2022): For year 2022, n = 2022 – 2010 = 12. Therefore, P2022 = P(1 + r)n = 5,773,552(1 + 0.009)12 = 5,773,552(1.009)12 = 5,773,552(1.1135) = 6,428,906 The population of Maryland 10 years from now (in year 2022) will be around 6,428,906. The...

Population growth

... Geometry and population growth are two issue in different fields that are somewhat related. The relationship in these two topics is mainly where one relies on another to get it value; this it to mean that population growth uses geometry to measure its parameters. Geometric growth rate is one of the formulas that are used to measure the growth rate in population. In geometric growth rates, each number is multiplied by a factor, for instance, 1, 4, 16, 64, 256, 1024, 4096, 16384, ........ This geometric series has been multiplied by a factor of 4, this kind of progression or growth is sometimes called exponential growth to mean something that grows very fast (Galan, Luard and Mazzucchelli, 65). Geometric growth can be contrasted... to...

Population Growth

...Population Growth Introduction The global population growth is deemed to reach 9.7 billion by the year 2050 andsubsequently 11.2 billion by the year 2100 which will pose unsustainability challenges to the mother earth. The main projection is perceived to be caused by Africa’s population which is rising at exponential rates. The rapid population growth has the effect of damaging the Earth’s natural-capital as well as increasing carbon-dioxide buildup in the ecosystem. Hence, population-control approaches are more effective than the traditional birth-control limitation, since they have long-term and...
