Land Use Policy Area (Lupa) Concept Model

Abstract

Abstract. The paper presents a Land Use Policy Area (LUPA) Concept Model adding the three basic elements: (i) ecosystem-based land use regarded as the intersection of the ecosystem and land use elements, (ii) subwatershed-based land use as the intersection of the subwatershed and land use elements, and (iii) integrated environmental management is the intersection of the subwatershed and ecosystem elements regarded as the Integrated Ecosystem Development Planning Unit (IE-DPU). The basic (spatial) elements are mathematically expressed as the paired sets of the three main variables, namely: ecosystem (dependent), watershed (dependent) and land use (independent) variables. The challenging work in this study was the development of a geospatial information model for use in policy areas LUPA applying these variables. There are four steps applied to answer the research objective, these are: ecological zone assessment, ridge-to-reef watershed delineation, land and water use heads-up mapping, ecosystem-based land use overlay analysis, watershed-based land use overlay analysis, integrated environmental management overlay analysis, and LUPA overlay analysis. The concept model analysis steers the geospatial information modeling for LUPA which carried the intersections of the paired variables: ecosystem-based land use, subwatershed-based land use and integrated environmental management as variating inputs to process by extracting the science-based information (overlay output) which practically highlighted the LUPA classification: (i) Protection with 49.1% or 3858.2 Ha of mangrove forest reserve and water use, (ii) Production areas with 46.5% or 3631.7 Ha mostly agricultural and aquacultural areas, (iii) Settlement with 2.7% or 209.2 Ha of urban and urban uses, and (iv) Infrastructure with 1.5% or 116.7 Ha of development. The authors concluded that land use policy areas will relatively change as land use changes which is also seen reliant on the impacts of climate change.

Land Use Policy Area (LUPA):A Stratagem towards Advanced Preparedness in the ArcGIS Platform

“…The LUPA is a stratagem that can guide the physical and environmental development in the Municipality of Lupi in the Province of Camarines Sur as it hints at providing information on where to tweak proper land and water utilization to stabilize and sustain food production while protecting the sensitive environment of the municipality (Abante et al, 2021).…”

“…It has location-defined coordinates and topological pointers to other features, possibly some non-spatial attributes (table form). The notion of Abante, et al (2021) on Land Use Policy Area (LUPA) features the ecosystem-based land use, sub-watershed, and integrated environmental management which were paired to analyze the ecological zones, ridge-toreef watershed delineation, land and water use, and the spatial features to classify the 1278 LUPA into four classes which are protection, production, settlement, and infrastructure. These intersections are mathematically expressed as the sets of {LUPA} ~ {ecosystembased land use} ∩ {watershed-based land use} ∩ {integrated environmental management} Abante, et al (2021).…”

According to them, the challenging work was creating the set of instruments in connection with land use policy areas with the following variables: ecosystem, watershed divide or delineation, land use, ecosystem-based land use, watershed-based land use, and integrated environmental management to extract the science-based information which practically highlighted the LUPA classifications, namely: Protection, Production, Settlement, and Infrastructure.…”

“…The study focused on creating the Land Use Police Area (LUPA) for Lupi, Camarines Sur with three sets of objectives to guide the municipal spatial growth to advance preparedness, these are: (i) physical development constraints highlighting the critical slopes relative to waterways and other environmental critical areas, (ii) land use classified into the forest, general agricultural areas comprising both the agricultural and settlements, and water use areas, and (iii) disaster-prone areas where risk hotspots are located which were based on the Abante et. al (2021) LUPA concept model highlighting the intersections of the three elements, namely: (i) intersection of the ecosystem and land use elements; (ii) intersection of the subwatershed and land use elements; and (iii) integrated environmental management.…”

“…The challenging work is correlating the 3 three sets of objectives to guide the municipal spatial growth to advance preparedness with the 3 elements of Abante et. al (2021) LUPA model which revealed land use policy areas as seen to influence the municipal growth of the municipality, although LUPA can relatively change as the independent variable "land use" changes which are also seen reliant on the impacts of climate change.…”
