Is a CHED-funded center dedicated to lead the development, implementation monitoring and evaluation of higher education researches in the Cagayan Valley.

The following are the climate change programs, projects and studies funded by CHED through HERRC:

Research Program 1 : Integrated Research and Development Program on Climate Change Resiliency and Environmental Protection
Program Leader : Dr. Dante M. Aquino
Project I : Climate Change Resiliency of Farming Systems in Cagayan Valley

Study 1 : Climate Change Vulnerability and Impact Assessment of Farming Systems
The farming systems were mostly located along the river flood plains planted to rice and corn. Farmers were mostly rice and corn farmers.
Climate variability and extremes experienced by farmers were typhoons, unpredictable rainfall patterns and drought that damage crops through strong winds and floods and inability to plant during long dry land periods.
Sources of climate change information (such as El Nino and Global Warming) of farmers were more on radio and TV.

Study 2 : Modeling Agroforestry as Climate Change Resilient Farming System
Existing agroforestry model farms had more diverse mix of field crops such as upland rice, corn and banana, tropical fruits (such as citrus and mango) and forest trees (Gmelina and mahogany) planted in sporadic/unarranged manner with water impoundments located in lowest elevations of the farms.
Selected existing model farms were located in upland rolling areas that could be allocated with field crops, tropical fruits, homelot and backyard and water impoundments as climate change-resilient land use components.

Study 3 : Policy, Advocacy, Extension and Training of Climate Change Resilient Farming System
Policies and programs of the LGUs were mostly on disaster risk reduction.
It is therefore important that the LGUs develop appropriate information, education and communication (IEC) materials in print and broadcast media and develop appropriate advocacy strategies and trainings on climate change resilient farming systems.
Topics identified for appropriate IEC materials based on the climate change AKAP focused on agroforestry/diversified farming.

Study 4 : GIS-based Cropping Systems Analysis and Climate Change Vulnerability Mapping of Farming Systems
All the tropical fruits (rambutan, Guimaras Mango, lanzones, pummelo) and bamboo were suitable to be planted in all the municipal study sites and selected model farms based on the ecological requirements of each.
Babaran, Echague, Isabela had the highest climate change vulnerability index considering that the main crop is only corn exposed to more frequent typhoons and drought.

Project II : Environmental Quality Assessment: Biophysical, Socio-Economic and Cultural Interrelationships in a Protected National Park
Project II Leader : Dr. Dante M. Aquino

Study 1 : Water Quality Dynamics AssessmentAccomplishments:

  • Acquired field and laboratory equipment/supplies/materials
  • Acquired maps
  • Conducted reconnaissance survey and established sampling sites
  • Collected and analyzed 57 soil samples within the riparian areas of the 5 barangays
  • Collected water samples for physicochemical analysis, macro benthic invertebrate samples using 3 samplers (1 for dry season- 24 sites and 1 for wet season- 8 sites)
  • Collected fish samples
  • Sorted and identified macro benthic invertebrates at the genus level
  • Partial data analysis of macro benthic invertebrates

Study 2 : Faunal Diversity and Management
Collected photographs and morphological measurements of trapped specimen

Study 3 : Socio-economics of Water Quality and Management

  • Gathered relevant literature (project reports, journal , theses, proceedings, etc.) and other secondary data for the study;
  • Conducted 300 interviews in the five barangays of the study area broken down as follows:
  • Sanitized interview schedules and encoded the data gathered from the interviews in Microsoft Excel database for analysis;
  • Conducted preliminary data analysis for presentation to and validation with stakeholders;
  • Attended the following training workshops as ISU representative in the Technical Working Group for the preparation of the Peñablanca Protected Area Landscape and Seascape (PPLS) Management Plan:
    • Agroforestry Assessment and Farm Planning for the PPLS
    • Identification and Mapping of Vulnerable and Hazard Areas in the PPLS
    • Sustainable Financing of PA Management and Climate Change Adaptation
  • Gathered additional information and conducted data validation through in-depth key informant interviews in the five barangays.
  • Conducted integrated data analysis with study 1 using GIS for draft article preparation

Study 4 : Community Adaptation and Mitigation on Water Use Dynamics

  • Work planning with research team (of both programs)
  • Participated in the PPLS working group tasked in the revision of the PA Management Plan as academe representative
  • Prepared and finalized interview schedule
  • Conduct of interviews of key informants
  • Documentation of livelihood (wet and dry farming, fishery, off-farm) practices
  • Identification and analysis of adaptation practices and strategies
  • Literature accumulation, data analysis and paper writing
