Demographic Dynamics and Water Needs in Sardinia: Understanding Population Trends

This seminar, led by Maria Luisa Gentileschi, explores the demographic trends in Sardinia, highlighting its status as Italy's third least densely populated region with 1,675,411 inhabitants as of 2010. It examines key statistics such as a birth rate of 8.1 and a total growth rate of 1.8, alongside the challenges posed by urbanization, population distribution shifts, and the impact of seasonal tourism on water needs. The discussion underscores the importance of population projections in planning for sustainable resource management in the face of demographic changes.

POPULATION FACTS IN SARDINIA • THE THIRD LESS DENSELY POPULATED REGION OF ITALY (69 hab./kmq) • AT THE ELEVENTH PLACE (AMONG THE 20 REGIONS) FOR NUMBER OF INHABITANTS(1.675.411 IN 2010) • RATES PER THOUSAND IN 2010: • BIRTH RATE 8,1 (ITALY 9,3) • DEATH RATE 8,7 (ITALY 9,7) • MIGRATORY BALANCE 2,4 (ITALY 5,1) • TOTAL GROWTH RATE 1,8 (ITALY 4,7) • AVERAGE TOTAL GROWTH RATE 2007/10: -0,6 (ITALY - 0,4)

  3. POPULATION DYNAMICS AND PROJECTION • THE END OF DEMOGRAPHIC TRANSITION • FEARING THE “DEMOGRAPHIC WINTER” • THE ROLE OF POPULATION PROJECTION IN PLANNING WATER NEEDS

  4. POPOLAZIONE SARDA E ITALIANA DAL 1861 AL 2001 (numeri indice: base 1861=100)

  5. POPULATION PROJECTIONS: 2007/2051 Population growth (2007/11) and population projection (2007/51)

  6. Regioni Agrarie classificate con SMD “Gravissimo o grave” e “Buono o discreto”

  7. TRADITIONAL PATTERN OF POPULATION DISTRIBUTION • THERE ARE MORE THAN 377 TOWNS AND VILLAGES • A VERY DISPERSED SETTLEMENT

  8. MAIN REDISTRIBUTION TRENDS • A GROWING URBANISATION RATE • A CHANGING DISTRIBUTION BETWEEN THE INTERIOR OF THE ISLAND AND THE COASTAL BELT • A GROWING CONCENTRATION ON THE COASTAL BELT • AN INCREASED CONCENTRATION IN THE NORTHERN AND SOUTHERN ENDS

  9. INTRA-REGIONAL POPULATION MOBILITY • THE SHIFT TO THE COAST • THE GROWING IMPORTANCE OF THE GATES OF ENTRANCE OF TOURISM (OLBIA, CAGLIARI, ALGHERO-FERTILIA)

  10. TOURISM AND POPULATION • BUILDING MORE HOUSES AND RESORTS • MORE PRESSURE FOR SEASONAL WATER CONSUMPTION • SECOND HOMES AS A PROMISE OF POPULATION GROWTH
