Development geography

Development geography is a specialized branch of geography. It focuses on the standard of living and the quality of life for human inhabitants. In this field, development is viewed as a process of change. This change can improve how people perceive their own lives. Geographers in this field study spatial patterns of development. They look for specific characteristics to measure progress. These characteristics include economic, political, and social factors. They seek to understand both the geographical causes and the consequences of these variations.

To understand these differences, geographers categorize countries into groups. They often compare More Economically Developed Countries (MEDCs) with Less Economically Developed Countries (LEDCs). They also look at variations within a single country. For example, they might study the Mezzogiorno in southern Italy. This helps researchers see how wealth can differ even in one nation. Some scholars, like Gunder Frank, have studied global economic forces. He proposed a dependency theory. This theory suggests that certain forces lead to the development of underdevelopment.

Experts use quantitative indicators to measure development through numbers. Economic indicators are very common. One major metric is Gross National Product (GNP) per capita. This measures the value of all goods and services produced by a country's citizens. It excludes goods produced by foreign companies. This helps measure a country's specific economic and industrial development. However, GNP per capita has several significant problems. It does not show how money is distributed among the population. In the UAE, for instance, oil wealth is often held by a small, rich elite. This means the money does not flow to the bulk of the country.

Another issue is that GNP does not measure human happiness. Many MEDCs see large increases in wealth without increases in happiness. Additionally, GNP often ignores the unofficial economy. This includes subsistence agriculture or unpaid work, which is common in LEDCs. Collecting accurate data in these areas can be too expensive. Some governments might also release inaccurate figures. Because exchange rates change, GNP is often converted using Purchasing Power Parity (PPP). This calculates the actual comparative purchasing power of money within a specific country. This provides a more accurate view of what money can actually buy.

Beyond money, researchers use social, demographic, and health indicators. Social indicators include access to clean water and sanitation. They also measure adult literacy rates. These show if a government can meet the needs of its people. Demographic indicators include birth, death, and fertility rates. These can indicate a country's level of industrialization. Health indicators are a sub-factor of demographics. They include nutrition, infant mortality, and life expectancy. They also look at the number of people per doctor. These metrics show the availability of healthcare and sanitation facilities.

There are also composite indicators that combine many different factors. The Human Development Index (HDI) is a well-known example. It is used to rank countries based on development. Another example is the Physical Quality of Life Index (PQLI). The PQLI was a precursor to the HDI. It used infant mortality instead of GNP per capita to rate countries from 0 to 100. The Human Poverty Index (HPI) is also used. It calculates the percentage of people living in relative poverty. There are two versions: HPI-1 for developing countries and HPI-2 for developed countries. HPI-1 looks at survival to age 40 and access to safe water. HPI-2 looks at survival to age 60 and income levels.

Geography plays a massive role in how a country develops. One famous pattern is the North-South divide, also called the Brandt Line. This line separates the rich North from the poor South. The North includes North America, Europe, Russia, Japan, and Australia. The South encompasses much of the rest of the world. However, this pattern is changing. Newly Industrialised Countries (NICs) like India, Brazil, and Mexico are developing very fast. This fast growth is driven by manufacturing and exports. This makes the old dividing lines less accurate over time.

Physical geography creates specific advantages or obstacles. Access to sea routes is a major advantage. Sea travel is faster and cheaper than land travel. This allows for the quick spread of resources and ideas. On the other hand, geography dictates the presence of disease. For example, malaria is associated with many nations struggling to develop. Disease can decrease labor productivity and change a country's age structure. Finally, agricultural productivity matters deeply. Temperate regions often have high grain output. In contrast, regions like the African savanna may have lower output. This can force more people into farming and slow down urban and technological growth.
