The table below presents the age structure of a municipal population in Nigeria obtained during a demographic survey:

Age Group (Years)	Population
$0 - 14$	$70,000$
$15 - 64$	$110,000$
$65+$	$20,000$

Based on these demographic data, what is the total age dependency ratio of this population?

45.00\%

81.82\%

122.22\%

63.64\%

Cevabı ve açıklamayı göster

Cevap: $81.82\%$

Cevap

The total age dependency ratio of the population is

81.82\%

The total age dependency ratio measures the demographic burden placed on the economically active population (

15-64

years). Combining the youth population (

70,000

) and old-age population (

20,000

) gives a total dependent cohort of

90,000

. Dividing this by the working-age population (

110,000

) and multiplying by

100

yields approximately

81.82\%

Adım Adım Çözüm

Identify the dependent population cohorts

Dependent population =

70,000 \text{ (aged 0-14)} + 20,000 \text{ (aged 65+)} = 90,000

Dependents consist of individuals under 15 years old and individuals aged 65 and above.

Identify the economically active (working-age) population

Working-age population =

110,000 \text{ (aged 15-64)}

The working-age group supports the dependent population.

Apply the total age dependency ratio formula

\text{Dependency Ratio} = \left( \frac{\text{Dependent Population}}{\text{Working-Age Population}} \right) \times 100 = \left( \frac{90,000}{110,000} \right) \times 100 \approx 81.82\%

The standard demographic metric measures the ratio of dependents per 100 working-age individuals.

In urban geography, classic land-use models like the Burgess Concentric Zone Model often fail to accurately reflect the spatial growth of rapidly growing cities in developing regions. Which of the following structural factors best explains why informal squatter settlements in developing metropolitan areas predominantly form on the urban periphery rather than within the inner-city transitional zone?

Extremely high land values and commercial gentrification in the central core force low-income rural migrants onto unmonitored peripheral lands where land enforcement is weak.

Abundant modern infrastructure and superior public municipal services on the rural-urban fringe serve as primary pull factors drawing rural migrants directly into outer districts.

The planned development of linear settlements along newly paved radial transportation highways automatically organizes squatter housing into structured suburban corridors.

An inverted demographic dependency ratio in the urban core forces dependent non-working populations to relocate to suburban zones to equalize municipal labor distributions.

Cevap: Extremely high land values and commercial gentrification in the central core force low-income rural migrants onto unmonitored peripheral lands where land enforcement is weak.

Cevap

Extremely high land values and commercial gentrification in the central core force low-income rural migrants onto unmonitored peripheral lands where land enforcement is weak.

The correct answer highlights that high commercial land prices in the urban center, combined with weak regulatory monitoring at the urban fringe, drive low-income migrants to establish informal settlements on inexpensive peripheral land.

Adım Adım Çözüm

Analyze classic urban land-use assumptions versus developing world urban realities.

Burgess's model assumes inner-city zones of transition host cheap housing for new migrants, whereas modern developing cities feature high central business district (CBD) commercial land values and gentrification.

Understanding land market dynamics explains why migrants cannot afford central locations.

Evaluate peripheral land dynamics in rapidly expanding metropolitan areas.

A manufacturing plant requires $3\text{ tonnes}$ of localized raw material to produce $1\text{ tonne}$ of finished product. The raw material deposit and the market are separated by a distance of $100\text{ km}$ . Transport costs are $\$2.00\text{ per tonne-km}$ for raw materials and $\$3.00\text{ per tonne-km}$ for finished goods. An alternative production site, Location L, offers a labor cost savings of $\$400.00$ per tonne of finished product, but increases the transportation distance of raw materials by $30\text{ km}$ and finished goods by $10\text{ km}$ compared to the least-cost transport point. Based on Alfred Weber's location theory, what is the net financial gain or loss per tonne of finished product if the plant relocates to Location L?

A net gain of

\$190.00

, indicating that Location L lies within the critical isodapane and is economically optimal.

A net gain of

\$310.00

, indicating that Location L reduces overall production costs significantly.

A net gain of

\$110.00

Cevap: A net gain of $\$190.00$ , indicating that Location L lies within the critical isodapane and is economically optimal.

Cevap

A net gain of

\$190.00

per tonne of finished product, placing Location L inside the critical isodapane.

According to Alfred Weber's Industrial Location Theory, the least-cost transport location for a weight-losing industry (

MI = 3 > 1

) is at the raw material origin, where moving input costs

\$6.00/\text{km}

versus

\$3.00/\text{km}

for output. Moving production to Location L adds

\$180.00

in raw material transport (

3\text{ tonnes} \times \$2.00 \times 30\text{ km}

) and

\$30.00

in finished goods transport (

1\text{ tonne} \times \$3.00 \times 10\text{ km}

), totaling

\$210.00

extra transport costs. Because the labor savings (

\$400.00

) exceeds the additional transport expense (

\$210.00

), Location L yields a net savings of

\$190.00

per tonne and lies inside the critical isodapane.

Adım Adım Çözüm

Determine the least-cost transport location

Transport cost per km for raw material assembly =

3\text{ tonnes} \times \$2.00/\text{tonne-km} = \$6.00/\text{km}

. Transport cost per km for finished goods distribution =

1\text{ tonne} \times \$3.00/\text{tonne-km} = \$3.00/\text{km}

. Since assembly cost per km exceeds distribution cost per km, the least-cost transport location is at the raw material deposit.

Weber's theory dictates that when the Material Index is greater than 1 (

MI = 3/1 = 3

), manufacturing is weight-losing and least-cost transport points favor raw material sites.

Calculate additional transportation costs incurred by moving to Location L

Additional raw material transport cost =

3\text{ tonnes} \times \$2.00/\text{tonne-km} \times 30\text{ km} = \$180.00

. Additional finished goods transport cost =

1\text{ tonne} \times \$3.00/\text{tonne-km} \times 10\text{ km} = \$30.00

. Total additional transport cost = \

180.00 + \$30.00 = \$210.00

Deviating from the optimal transport location increases movement costs for both input and output.

Compute net financial impact incorporating cheap labor savings

Net financial advantage = Labor cost savings - Total additional transport cost = \

400.00 - \$210.00 = +\$190.00\text{ per tonne}

If labor savings exceed the additional transport costs, the factory relocates to the labor site (Location L lies within the critical isodapane).

In many rapidly growing metropolitan areas in developing nations, severe morning traffic gridlock routinely occurs along major arterial roads leading into the city center. This phenomenon is largely caused by tidal commuting movements from distant residential suburbs to central commercial districts. Which of the following urban spatial planning issues is the primary structural driver of this daily traffic congestion?

Functional segregation of urban land uses, which concentrates commercial employment in the central business district while residential developments expand peripherally.

Reversal of migration push factors, where favorable economic conditions in rural areas force workers to commute into urban centers during peak morning hours.

Misidentification of nucleated commercial hubs as linear settlement patterns along major transport routes, which artificially creates traffic bottlenecks.

Cevap: Functional segregation of urban land uses, which concentrates commercial employment in the central business district while residential developments expand peripherally.

Cevap

Functional segregation of urban land uses, which concentrates commercial employment in the central business district while residential developments expand peripherally.

Functional segregation separates residential areas from commercial and industrial employment zones. When jobs are concentrated in the central business district and housing expands peripherally, workers must travel long distances along the same routes at the same times, resulting in severe tidal traffic congestion.

Adım Adım Çözüm

Analyze the observed urban problem

Identified severe daily traffic gridlock caused by unidirectional peak-hour commuting (tidal commuting) from suburbs to the central core.

Understanding the spatio-temporal flow of urban commuters helps identify the spatial structure underlying the traffic problem.

Evaluate urban land-use principles

Recognized that when cities lack mixed land-use planning, commercial and employment functions remain centralized while housing moves to the periphery.

Functional segregation forces residents to travel long distances simultaneously to access employment nodes, overwhelming transit corridors.

Select the correct spatial driver

Concluded that functional land-use separation is the main structural cause of tidal commuting and traffic congestion.

Integrating land uses (mixed-use planning) reduces commuting distance and distributes traffic more evenly across urban space.

Malthusian Population Theory matches the principle of exponential population growth versus linear food supply growth. Optimum Population Concept matches the state yielding maximum per capita output given available resources and technology. Neo-Malthusian Theory matches modern advocacy for contraception and resource sustainability. Demographic Dividend matches economic growth resulting from a shift toward a larger working-age population proportion.

Each population concept is matched with its accurate defining principle: Malthusian theory explains geometric population growth against arithmetic food expansion; Optimum population represents maximum per capita output; Neo-Malthusian theory advocates birth control and resource sustainability; and Demographic dividend represents economic benefit from a favorable working-age population structure.

Adım Adım Çözüm

Identify the foundational tenet of Thomas Malthus's population essay.

Malthus posited that human population expands exponentially (geometrically) while food production increases linearly (arithmetically).

This establishes the classic imbalance between population growth rate and food supply capabilities.

Define the equilibrium target of optimum population.

Optimum population occurs when resource development and technological efficiency yield maximum per capita economic return.

It distinguishes underpopulation and overpopulation states relative to resource efficiency.

Examine the modern adaptation under Neo-Malthusian theory.

Neo-Malthusians adapt Malthusian concerns to contemporary environmental limits, promoting active family planning and resource management.

It highlights proactive human intervention rather than relying solely on positive checks like war or famine.

Analyze the demographic structure required for a demographic dividend.

A demographic dividend occurs when falling fertility lowers youth dependency, expanding the working-age population relative to non-working dependents.

It links age structure transition directly to economic growth opportunities.

Cevap: Depletion of agricultural soil fertility leading to poor crop yields

Cevap

Depletion of agricultural soil fertility leading to poor crop yields

Soil fertility depletion directly undermines rural agricultural production and livelihoods. Because rural economies depend heavily on farming, severe land degradation creates hardship that forces rural dwellers out of their villages to seek survival in urban centers.

Adım Adım Çözüm

Define push factors in the context of rural-urban migration

Push factors are unfavorable socio-economic or environmental conditions in rural origin areas that force residents to migrate.

Understanding the distinction between push factors (negative rural conditions) and pull factors (positive urban attractions) is key.

Evaluate the options against rural push factor characteristics

Declining soil fertility directly impairs agricultural productivity, causing rural poverty and pushing farmers to seek urban employment.

Degraded natural resources in rural areas act directly as economic push motivators.

The new network ratio is computed using the updated totals of edges and vertices.

Calculate the net change between Phase 1 and Phase 2

\Delta \beta = \beta_2 - \beta_1 = 1.80 - 1.50 = +0.30

Subtracting the Phase 1 index from the Phase 2 index provides the net increase in connectivity.

Why are palm oil processing mills in southern Nigeria predominantly situated within or near oil palm plantations rather than close to urban consumer markets?

Oil palm fruit is a weight-losing and perishable raw material that must be processed immediately to prevent degradation.

Palm oil processing is a weight-gaining industry that increases bulk during production.

Processing mills operate as footloose industries with no dependency on raw material location.

Urban consumer markets impose strict environmental zoning bans on all food processing factories.

Cevabı ve açıklamayı göster

Cevap: Oil palm fruit is a weight-losing and perishable raw material that must be processed immediately to prevent degradation.

Cevap

Palm oil processing mills are located near plantations because fresh fruit bunches are heavy, bulky, weight-losing, and highly perishable, making raw material proximity the primary least-cost location factor.

The correct option highlights that oil palm fruit bunches lose weight during milling and decay quickly if not processed immediately. Following Weber's least-cost location theory, processing raw materials that undergo significant weight reduction or rapid spoilage takes place near the point of harvest to reduce haulage costs.

Adım Adım Çözüm

Analyze the nature of the raw material (oil palm fruit bunches).

Oil palm fruit bunches are heavy, bulky, and subject to rapid deterioration (free fatty acid buildup) after harvesting.

Understanding raw material characteristics dictates transport cost behavior according to industrial location principles.

Determine weight change during processing.

Extraction yields a smaller weight of oil compared to the heavy weight of fresh fruit bunches, classifying it as a weight-losing process.

In agricultural geography, Ester Boserup's model demonstrates how increasing population density drives progressive land-use intensification by shortening the fallow period. Arrange the following traditional and modern agricultural systems in order of INCREASING land-use intensity and frequency of crop harvesting (from the lowest cropping frequency to the highest cropping frequency).

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence of agricultural systems from least intensive to most intensive is: Forest fallow system → Bush fallow system → Short / Grass fallow system → Annual cropping system → Multi-cropping continuous system.

Boserup's theory demonstrates that agricultural land-use transitions systematically under population pressure from extensive land use (forest fallow with 20–25 years resting) to bush fallow (6–10 years resting), short/grass fallow (1–2 years resting), annual cropping (single annual crop), and finally continuous multi-cropping (zero fallow, multi-harvest).

Adım Adım Çözüm

Identify the core metric of Boserup's agricultural intensification theory

Intensity of agricultural land use is inversely proportional to fallow length and directly proportional to cultivation frequency.

The theory establishes that as population pressure rises, long fallow periods are progressively shortened.

Evaluate the fallow duration of extensive farming systems

Forest fallow (20–25 years fallow) is less intensive than bush fallow (6–10 years fallow).

Forest fallow allows complete ecological succession back to primary/secondary forest before re-clearing, giving it the lowest cropping frequency.

Evaluate short-cycle fallow systems

Short/grass fallow (1–2 years fallow) sits between bush fallow and permanent cultivation.

Short fallow cycles occur under high land scarcity where woody vegetation can no longer re-establish.

Order permanent and semi-permanent cropping systems

Annual cropping (one harvest per year) is followed by multi-cropping (multiple harvests per year with zero fallow).

Multi-cropping continuous systems utilize advanced land management (irrigation, fertilization, intercropping) to yield multiple crops annually from the same plot.

In spatial agricultural location theory, an isolated central market is surrounded by a uniform plain. If freight rate is directly proportional to product weight and perishability, which of the following best explains why intensive market gardening occupies the innermost ring closest to the market city while extensive livestock ranching operates in the outermost ring?

Perishable produce yields higher economic rent per unit area, enabling farmers to outbid extensive land uses for high-value land near the market.

Cheaper land values near the urban boundary permit the large-scale spatial allocation required for labor-intensive crop cultivation.

Specific microclimatic conditions and dry soil profiles suitable for horticulture occur exclusively in urban fringe areas.

Nucleated rural settlement patterns near the market physically restrict livestock movement and grazing networks.

Cevap

Perishable produce yields higher economic rent per unit area, enabling farmers to outbid extensive land uses for high-value land near the market.

In agricultural location theory, land close to the market commands the highest economic rent. Intensive horticulture and dairying produce high value per unit area but suffer high transport costs and rapid spoilage. Consequently, growers of these products have a steep bid-rent curve and can outbid extensive land uses (like grain production or livestock ranching) for the most accessible, high-rent land adjacent to the central market.

Adım Adım Çözüm

Analyze the spatial economics of Von Thünen's agricultural land use model.

Economic rent (Locational Rent) decreases with increasing distance from the central market due to rising transportation costs.

Economic rent is defined as revenue minus production costs and transportation costs.

Compare the transport and yield characteristics of intensive horticulture versus extensive ranching.

Horticultural products have high yield per hectare, high perishability, and high transport costs per unit of land, producing a steep bid-rent gradient.

Perishable goods must reach the market quickly, making proximity to the central market critical to profitability.

Determine why land allocation occurs in concentric rings.

Activities with the steepest bid-rent curves outbid other activities for land closest to the market, establishing intensive gardening in the innermost zone.

Ranching produces low revenue per unit area and lower transport cost per hectare, meaning it can only operate profitably where land rent is lowest (farther from the city).

An inland freight transport authority is evaluating the connectivity of a regional railway network serving heavy industrial nodes in West Africa. In the baseline phase, the connected planar network ( $p = 1$ ) consists of $8$ urban freight terminals (vertices) linked by $11$ direct rail corridors (edges). Following an expansion project, $2$ new freight terminals and $4$ additional rail corridors are integrated into the existing system. What is the net change in the topological Alpha index ( $\alpha$ ) of the network as a result of this expansion?

Cevap: An increase of $\frac{2}{55}$

Cevap

The net change in the topological Alpha index of the network is an increase of

\frac{2}{55}

The correct response accurately applies the Alpha index formula for planar graphs: $\alpha = \frac{e - v + p}{2v - 5}$. For the baseline phase, $\alpha_1 = \frac{11 - 8 + 1}{2(8) - 5} = \frac{4}{11}$. For the expanded phase with 10 vertices and 15 edges, $\alpha_2 = \frac{15 - 10 + 1}{2(10) - 5} = \frac{6}{15} = \frac{2}{5}$. The difference $\frac{2}{5} - \frac{4}{11} = \frac{2}{55}$ represents the exact increase in topological network connectivity.

Adım Adım Çözüm

Identify the formula for the Alpha index ($\alpha$) of a planar transport network

The formula is $\alpha = \frac{e - v + p}{2v - 5}$, where $e$ is edges, $v$ is vertices, and $p$ is the number of non-connected subgraphs ($p = 1$ for a connected graph).

The Alpha index measures the degree of connectivity by comparing the actual number of fundamental circuits (cyclomatic number) to the maximum possible number of circuits in a planar graph.

Calculate the baseline Alpha index ($\alpha_1$)

For $v_1 = 8$ and $e_1 = 11$, $\alpha_1 = \frac{11 - 8 + 1}{2(8) - 5} = \frac{4}{11}$.

Substitute the initial numbers of terminals and rail corridors into the formula.

Calculate the post-expansion Alpha index ($\alpha_2$)

After adding 2 terminals and 4 corridors, $v_2 = 10$ and $e_2 = 15$. Thus, $\alpha_2 = \frac{15 - 10 + 1}{2(10) - 5} = \frac{6}{15} = \frac{2}{5}$.

Update total vertices and total edges to compute the expanded network's connectivity ratio.

Determine the net change ($\alpha_2 - \alpha_1$)

$\alpha_2 - \alpha_1 = \frac{2}{5} - \frac{4}{11} = \frac{22 - 20}{55} = \frac{2}{55}$.

Subtract the baseline Alpha index from the post-expansion Alpha index.

Cevap

Informal Settlements match with rapid rural-urban migration exceeding housing capacity; Urban Heat Island Effect matches with replacement of natural vegetation with heat-absorbing surfaces; Urban Sprawl matches with unplanned outward expansion into rural hinterlands; Traffic Congestion matches with high concentration of private vehicles and insufficient mass transit.

Each urban challenge directly corresponds to its primary spatial or environmental driver: informal settlements are caused by migration outpacing housing; urban heat islands stem from impervious surface thermal storage; urban sprawl represents unplanned peripheral expansion; and traffic congestion is driven by vehicle volume exceeding transit capacity.

Adım Adım Çözüm

Analyze Informal Settlements (Slums)

Identify that rapid influx of migrants combined with severe urban housing shortages drives informal settlement development.

Slums represent direct socio-spatial manifestations of population growth exceeding infrastructural capacity.

Analyze Urban Heat Island Effect

Associate elevated urban microclimatic temperatures with artificial heat-retaining materials (asphalt, concrete) replacing vegetation.

Surface energy balance is altered in built urban environments compared to surrounding rural areas.

Analyze Urban Sprawl

Match with low-density, uncontrolled outward physical expansion across rural-urban fringes.

Sprawl describes a specific spatial growth pattern across city boundaries rather than high-density vertical development.

Analyze Traffic Congestion

Match with automobile density exceeding transportation network capacity.

Gridlock stems from infrastructure capacity bottlenecks and private vehicle reliance.
