Island day tours have become a ubiquitous inclusion in travel itineraries. Marinduque is one of the Philippine islands where its major tourist attractions can be covered by day tours. This study determines an itinerary of select tourist spots for island day tours in Marinduque. The longitude, latitude of each tourist spot and the pairwise road distances were determined. Every tour was assumed to start and end at the same point, either at Marinduque Airport or at Balanacan Port, and would last for at most 8 h. To determine the optimal route for the different types of tours (general and themed), an integer programming model was formulated. Balanacan port is the point of origin for three of the four identified tours. The general tour is the ideal choice for those who want to maximize theme diversity. The history-themed and church-themed tours are covered in at least three of the four tours. All tours ran from 7.5 to 8 h. All themed-tours covered their themed points except for the cave-themed. All points except one were visited in at least one tour. Three of the four pilgrim points were visited in all tours, while the cave sites were only visited in the cave-themed tour. The results of this study are beneficial to the community of Marinduque, as these will contribute to the tourism management plan of the province. The model may be extended to consider other tourist destinations.

A crop rotation model for Marinduque, Philippines

Crop production faces an increasing threat due to anthropogenic activities and natural hazards. Crop rotation is a tool that can address these issues in crop production. This study proposes an optimization model that generates a crop rotation plan using spatiotemporal suitability scores given a set of crops, with an objective to maximize the total suitability of the assignment of crops while satisfying principles of crop rotation such as suitability threshold and crop succession requirements. Biophysical and climatic characteristic data from Marinduque, Philippines, with upland rice, corn, and mungbean as crops, were used to validate the model. The results show that with a minimum suitability threshold of 0.6, an optimal crop rotation plan for one annual cycle included corn and mungbean for one (May to October) and two (June to August, September to November) cropping periods, respectively. Throughout each cropping period, the corn and mungbean will cover 46.64% and 10.33% of the arable land, respectively. Based on the crop rotation plan, corn can be cultivated along the shorelines except in the southeast area of the island, where mungbean is more suitable. The results suggest that other crops should be considered since the current set of crops leaves 43% of the arable land unutilized. This model can be used for any combination of crops and other spatiotemporal suitability factors, allowing it to be applied to different sites and scenarios.
