Linking the economy to the ecosystems: land use change and ecosystem services valuation at basin level

Forecasting Urban Expansion in the Seven Lakes Area in San Pablo City, Laguna, the Philippines Using the Land Transformation Model

“…Driver maps were prepared using the programme ArcMap. Topographical shapefiles for creating the driver maps were provided by the National (Liu et al, 1993;Pijanowski et al, 1997;Singh, 2003) Distance to Trails Functions similarly to roads by increasing accessibility to an area; observed that some built-up areas deviate from the roads Distance to Lakes Lakes provide sources of livelihood, food and water for various uses Distance to Existing Built-up Built-up areas tend to expand within their proximity (Pijanowski et al, 1997;Singh, 2003) Population Density Highly populated areas are more prone to conversion (Mulatu, 2014;Pijanowski et al, 1997) Slope Area may be prone to change if not near an urban centre simply due to flat terrain (Singh, 2003); Less slope also minimizes landscaping costs (Tayyebi, Pijanowski, & Tayyebi, 2011) Source: Authors.…”

“…The factors which drive LULCC can vary from factors contributing to accessibility, such as proximity to an existing road network (Pijanowski, Long, Gage, & Cooper, 1997;Singh, 2003), pressure to urbanize given proximity to an already built-up area (Pijanowski et al, 1997) as well as high-density areas (Pijanowski et al, 1997). Socio-economic opportunity is also a driver of land use change (Mulatu, 2014), which can be manifested from resource extraction from the lake areas, especially since aquaculture and fishing activities were observed.…”
