Spatial Development – Key Concepts (Introductory Lecture)

Introduction to Spatial Development

Spatial development = relationship between socio-economic development and space; implications for decision-making and distribution of activities.
Course uses theoretical foundations and empirical applications; introduces basic tools to analyse economic and spatial development.

Introduce the spatial dimension of economic concepts.
Introduce analytical techniques in spatial planning.
Provide understanding of the theoretical basis of economic and spatial development.
Equip skills to relate spatial, economic, social, and political concepts to development strategies at appropriate administrative levels.

Spatial analysis = geographical/locational analysis explaining patterns of human behaviour in space using quantitative and spatial concepts.
Process: examine locations, attributes, and relationships of features in spatial data (overlay, etc.) to address questions or gain knowledge.
It extracts or creates new information from spatial data.

The Economic Man: a theoretical agent with perfect knowledge acting to maximize profits.
Economics: study of production, distribution, and consumption of goods and services; scarcity and choice; decision-making; uses models or data to explain social phenomena.
Microeconomics: demand, supply, market equilibrium, elasticity, opportunity costs, production decisions, etc.
Macroeconomics: total national output/income, unemployment, balance of payments, inflation; links to how individual and macro decisions affect spatial development.

Traditional measures: Gross National Product ($GNP$); poverty, inequality, unemployment concerns.
Post-1970: redistribution with growth as a broader aim.
Dudley Seers’ questions: what happens to poverty, unemployment, and inequality? A decline in any of these signals development; worsening in any can indicate lack of development.
Todaro & Smith (2010): development as multidimensional; changes in social structures, institutions, growth, inequality, and poverty reduction.
Amartya Sen’s Capability Approach: development = enhancing lives and freedoms; Functionings vs. Capabilities.
Core values (Todaro & Smith):
- Sustenance: meeting basic needs (food, shelter, health).
- Self-esteem: sense of worth and dignity.
- Freedom from servitude: real choices, rule of law, security, political participation.
- Lewis: growth expands the range of human choices, not just wealth.

Economic development has spatial implications (man-land relationship).
Spatial development reflects economic development and exhibits spatial inequalities.
Africa’s urbanisation: rapid growth expected from 2010 to 2030, with urban share rising from 36\% to 50\%.
Spatial development is influenced by theories: location theory (central place, Von Thünen, Weber, Christaller), core-periphery, growth pole, agropolitan, cumulative causation, endogenous development.

Africa: spatial inclusion gaps; concentration of activities in coastal hubs (e.g., Abidjan, Dakar, Lagos, Lomé).
Long-term challenges for spatial planning: rapid rural-urban migration, strain on urban infrastructure, urban poverty, over-concentration of services in cities, weak planning policies and inter-sectoral coordination.
Peripheral regions are poorly connected to hubs; uneven development across cities and countryside.
Issues: food insecurity, limited access to education/health, informal housing, rural poverty, mass transit inefficiency in low-density urban areas.
Spatial fragmentation (historic apartheid in SA as example): informal settlements, slums, poor basic services, congestion.
Urbanisation trends: significant growth in Africa’s urban populations; need for strategies to manage growth and ensure inclusive development.
