The concept of spheres of influence for sporting and touristic facilities

The sphere of influence refers to the geographical area from which a facility or attraction draws its visitors or supporters.

Understanding spheres of influence

• Definition and scope - A sphere of influence, also known as a catchment area, represents the region that supports a particular facility or service by providing users or visitors.
• Threshold population - This is the minimum number of people required to sustain a facility. Smaller facilities need fewer people, while larger ones require a bigger population base.
• Range of influence - This indicates the maximum distance individuals are willing to travel to access a facility. A local playground might have a range of just a few kilometres, whereas a major stadium could draw people from across a country or beyond.

Hierarchies of sporting facilities and their catchment areas

Sporting facilities vary widely in size, purpose, and the areas they serve. They can be arranged in a hierarchy based on their sphere of influence, reflecting the community size they cater to and the types of activities they offer.

Hierarchy of sporting facilities by sphere of influence

Specific population thresholds for sporting facilities

• Golf courses - In the UK, an 18-hole golf course typically requires a threshold population of around 30,000 people.
• Playing fields - It is recommended to provide approximately 3 hectares of playing fields for every 1,000 people in a community.
• Baseball pitches and tennis courts - In the USA, baseball pitches have a threshold population of about 6,000, while tennis courts require around 1,000 people to be sustainable.

Spheres of influence for tourist attractions

Tourist attractions often have broader spheres of influence compared to local sporting facilities, drawing visitors from national or even international regions. The scale of their catchment area depends on the uniqueness and appeal of the attraction.

Categories of tourist attraction spheres

• Local and national attractions - Some destinations, such as smaller national parks like Addo Elephant Park in South Africa, primarily attract visitors from within the country or nearby regions.
• National and international attractions - Places like Oxford in the UK or Killarney National Park in Ireland draw both domestic and overseas tourists due to their cultural or natural significance.
• Global attractions - Major cities such as London, Paris, and New York have a worldwide sphere of influence, appealing to millions of international visitors annually.
• Specialised holiday destinations - Certain attractions, like Centre Parcs in the UK or Camp America in the USA, have more localised or niche appeal, often catering to specific interests or demographics.

Location factors for national parks

• Remote natural beauty - Many national parks are situated in rugged, scenic areas far from urban centres, enhancing their appeal as escapes to nature.
• Urban proximity - Some parks, such as Sanjay Gandhi National Park in Mumbai or Nairobi National Park in Kenya, are located near or within urban areas, making them accessible to city dwellers.

Factors affecting the geography of national sports leagues

The geographical distribution and support base of sports teams in national leagues are influenced by various factors, including the level of the league and the mobility of fans. These elements shape the sphere of influence for different teams.

Influences on sports league geography

• Top-tier leagues - Teams in the highest divisions often enjoy a wide sphere of influence, with some clubs boasting a global fan base who follow matches through media like television or online platforms.
• Lower-tier leagues - Teams in lower divisions typically have a more localised support base due to limited success or visibility, restricting their sphere of influence to nearby areas.
• Fan mobility - Supporters may relocate for education or employment, expanding a team’s fan base beyond its immediate geographical area, even for smaller clubs.

Case studies on rugby in South Africa and Gaelic Games in Ireland

Rugby in South Africa: The Currie Cup

• Overview - Rugby is a major sport in South Africa, along with soccer and cricket, with historical associations as a predominantly white sport during apartheid, while soccer was more popular among black and coloured communities.
• Currie Cup structure - This is South Africa’s premier provincial rugby competition, running since 1892. It includes 14 teams split into a Premier Division (8 teams) and a First Division (6 teams).
• Historical success - Up to 2015, Western Province (based in the Western Cape) was the most successful team, followed by the Blue Bulls (formerly Northern Transvaal). No single team has consistently dominated since rugby turned professional in the 1990s.
• Sphere of influence - Teams draw support primarily from their provincial regions, such as the Golden Lions or Natal Sharks, though national interest in the Currie Cup extends the influence wider, especially for top teams.
• International participation - In 2017, the Free State Cheetahs joined the Rugby Union Pro12 league, competing with teams from Ireland, Wales, Scotland, and Italy, showcasing an expanding international sphere of influence.

Gaelic Games in Ireland

• Overview - Gaelic Games, including hurling, Gaelic football, and camogie, are organised at a county level across the Republic of Ireland (26 counties) and Northern Ireland (6 counties).
• Competition structure - Teams compete in a merit-based national league and a knock-out competition. The knock-out format starts with provincial competitions across four provinces, leading to the All-Ireland semi-finals and final.
• Sphere of influence - Support is largely county-based, with fans strongly tied to their local area, though migration for work or study can broaden a county team’s following beyond its borders.
