    Seaweed culture as a livelihood source: A case in Barangay Bato, Sta. Cruz, Davao del Sur
    Bacaltos, Della Grace G.; Revilla, Nila Nanette S.; Noel, Helen W.; Antonio, Emily S.; Gultiano, Joven O.; Besas, Jesebel (Southern Philippines Agri-Business and Marine and Aquatic School of Technology, 2004)
    As an offshoot of the Technology Innovation, Promotion, and Commercialization Program (TIPCP) initiated by Land Bank of the Philippines and DOST-XI, this study was conducted to feature actual seaweed culture practices in barangay Bato, Sta. Cruz, Davao del Sur. This initiative may be a way to provide inputs for the development of strategies for greater seaweed production. Specifically, the study aims to identify variations in culture practices, determine production, and provide venue for extending assistance to seaweed growers. Purposive sampling was done and 73% of the actual seaweed growers in the site were interviewed. Results show that most culture practices of seaweed growers in the study site vary from the recommended ones. Volume of seaweed production, as declared by the respondents, is slightly low but not quite far from the values recorded for the seaweed farms in Western Mindanao. It was worth note taking that more than half of the seaweed growers in barangay Bato finance the farms they operate and the rest are assisted by buyers. This may call for a need of a sound financing scheme by funding institutions. Similarly, the low production, in terms of volume and income, may also be an important concern wherein interventions for technical assistance and marketing strategy have to be pursued.

    Identifying suitable sites for pump irrigation system from open source and shallow tube well in selected areas of Davao Del Sur through geographic information system-based water resources assessment
    Trondillo, M. J. F.; Generallao, I. C .; Valleser, R. A. R.; Lopez, M. T.; Janson, A. Z., Jr.; Bejarasco, J. A.; Toriales, I. R., Jr. (2019-05)
    This paper features the Geographic Information System (GIS) in identifying suitable sites for small scale irrigation projects (SSIP) particularly pump irrigation system from open source (PISOs) and shallow tube well (STW) through water resource assessment. The development of GIS-based assessment model for SSIP and resource map in aid of SSIP planning and development is limited in some municipalities. To develop a reliable GIS-base framework, the ArcGIS tool and spatial method was used in compiling specific factors with field analysis and developing regional resource map for SSIP. The results showed that STW in Digos City and Municipality of Hagonoy is 117 units and 17 units respectively. The average water depth in existing STW is within the 6.5 meters with capacity to irrigate 3 to 5 hectares per unit, low investment with high water use efficiency and simple to operate. It was found out that most STW is provided by Department of Agriculture-Regional Field Office XI and Local Government Units. The STW is suitable for Digos City with an area of 379.32 hectares. While the PISOS were identified with different range of pump horsepower. There are 10 units of PISOS in Digos City and 15 units in Hagonoy mostly provided by National Irrigation Administration-XI. It was found out that in Digos City the 1,855.53 hectares are highly suitable and 14,377.55 hectares are not suitable for PISOS. The results of this study may assist the decision making processes for planning and development of SSIP using the developed protocol and tools for different purpose in agricultural production in Davao del Sur, Region XI and the whole country.
