Assessments of Climate Change Impacts and
Mapping of Vulnerability to Food Insecurity under
Climate Change to Strengthen Household
Food Security with Livelihood Adaptation
Approaches
Introduction AMICAF is a comprehensive framework by the Food and
Agriculture Organization (FAO) of the United Nations that aims to address climate change impacts and adaptation planning targeted at improving the food security of vulnerable household groups.
In the Philippines, the AMICAF framework is currently being implemented in cooperation with the Department of Agriculture with funding from the Japanese government.
The Philippine activities started in January 2012 and it will end on October 2014 for a 3-yr implementation.
AMICAF Framework: Addressing the Linkage Between Climate Change and Food Security
To assist developing countries to address climate change assessment and adaptation, to improve food security through a comprehensive framework.
This framework would bridge climate change impact assessment, food Insecurity vulnerability analysis and livelihood adaptation approaches.

Step 1: Impacts of climate change on agriculture MOSAICC – Modeling System
for Agricultural Impacts of Climate Change
Multiple impact models (Climate downscaling, Crops, Hydrology, Economy) in one package
Crop model uses downscaled climate data, not hydrology outputs. Hydrology and crop models run in parallel. The results from hydro and crop are together used in PAM
Developed Partial Equilibrium model, named PAM (Provincial Agricultural Market Model) as link to VA (Step 2)

Climate Downscaling for Precipitation2 climate scenarios and 3 models
PAGASA has completed the final runs of the statistical downscaling for two scenarios (A1B, A2) and 3 models (BCM2, CNCM3, ECHMA5) with topography as a major consideration
Results have high statistically probability functions
Analysis confirmed the maximum interpolation parameter set at 2000 mm;
GCMs with highest percent changes in precipitation (i.e. 1162%: MPEH5 A1B) are still found to be reasonable; and
December-January-February and March-April-May have positive % changes, which mean dry months are becoming wetter.
% change in rainfall
Hydrology modelling using STREAM by UP-NIGS
UP-NIGS has finalized results using the hydrology model (STREAM ) on 14 major river basins and provinces
Projections for river discharges were up to 2050 for 3 models and 2 climate change scenarios using climate projections from PAGASA
Crop Modeling (WABAL) by PhilRice WABAL Crop model uses historical BAS data on crop yield linked with calculated
PET from downloaded rainfall, temperature & crop coefficient Runs using final climate data uploaded in MOSAICC server has been done for
four provinces representing 4 climate types (Nueva Ecija, Isabela, Agusan del Sur and Camarines Sur)
Review by FAO technical officers of the results are on-going before proceeding to other provinces
Provincial Agricultural Market Modeling by NEDA
PAM through partial equilibrium model (excel based) has been developed for irrigated & rainfedrice, and corn production linked to climate variables
Yield output from crop model is used and area harvested change in PAM according to supply/demand
Covers 79 provinces and 2 cities with 2010 as base year and projection is until 2030
PAM is calibrated with prices statistics from BAS
Retail price, Provincial level
Step 2: Food Insecurity Vulnerability Analysis
Develops an analytical econometrics model with the best available national household datasets; Climate information will be used to construct relevant climate shocks (level, volatility and seasonality) to assess their impact at household welfare to characterize vulnerability
Identify variables associated with highest levels of vulnerability; Explore and identify the channels through which climate changes pass through at the household (farm) level and welfare
Identify and map vulnerable groups (profiling); Considering adaptive capacity options of farmers (economic level)
Exploration of the efficiency of different policy tools (simulations

The decrease in the annual rainfall by 2030 will lead to 0.0013 increase in the probability of being food poor
Similarly, the decrease in annual rainfall by 2050 will lead to increase in the probablity of being food poor by 0.44 percent
Step 3 Livelihood Adaptation to Climate Change
Identification, validation, field-testing, and evaluation of good adaptation practices at local context through participatory processes and capacity development under the framework of Climate-smart Farmer Field Schools
Field-testing sites are Camarines Sur and Surigaodel Norte with drought, flooding and saline intrusion issues

Testing of CCA options in stressed areas under CS-FFSAMICAF Partners: DA RFU 5, DA Caraga and PhilRice Agusan, selected LGUs
The CCA options (multi-stress tolerant rice lines and rice-duck system) are tested side by side with farmer’s practices in drought, saline-intrusion and submerged areas - managed by CSFFS with AEWs
Products developed for local CCA… A Facilitator’s manual for LGU
AEWs in conducting CSFFS (in collaboration with RWAN) has been distributed and are now used as reference for similar FFS initiatives by other projects
A reference manual for LGUs in setting up and operation of climate information center with PAGASA and RWAN – for printing
Other GPOs introduced through the FFS
• Use of a simple rain gauge to monitor the precipitation at community and farmer’s level;
• importance of using farm weather bulletin (developed by DA 5) in farm decision making and schedule of field operations;
• Typhoon tracking exercises by farmers to monitor the path of typhoons;• PalayCheck system for irrigated and rainfed rice like use of one seedling per
hill, use of 40 kg/ha seeding rate, use of MOET and LCC, as well as IPM and AESA to monitor crop performance over time;
• Intercropping upland rice with corn plants (as border plants) for additional food and source of income;
• Homestead gardening to FFS farmers by provision of vegetable seeds; • Use of IRRI superbag for storing farmer seeds up to 1-year; and• Use of burnay earthen jars for storing some amount of emergency food during
calamities.
Step 4 Institutional analysis and awareness raisingPartners: Climate Change Commission, DA-CCO and NEDA
NEDA and FAO has concluded the discussion for the conduct of policy analysis and simulation studies; training of NEDA staff on policy simulation done, July 1, 4
A workshop for institutional analysis on Sept. 17, 2013 with CCC as lead convenor: Overview of sectoral climate change
frameworks and programs: CCC, NDRRMC, DA, DENR, DAR, DOST
— Initiatives and focus towards convergence and mainstreaming
— Participants from both government, NGOs and academic institutions
Policy Simulation using PAM model
The ratio of government agriculture expenditure vs. total is statistically significant and it leads to an increase in irrigated yield.
Both max and min temperature have a negative impact on both irrigated and rainfed palay yield. However, only max temperature is statistically significant.
Precipitation has a positive impact on rainfed yield and is statistically significant.

Impact of Policy and Climate Variables on Palay Yield, 1981-2010 (Preliminary)
Projection of Yield under Climate Change ScenarioProjected Average Palay Yield under Climate Change Scenario, 2011-2030
Note: Figures are 2011-2030 averages; Simulation refers to 5% annual increase in government agriculture expenditure ratio; C.V. is the coefficient of variation.
• Palay yield is projected to be lower under A2 Scenario (4.219 mt/ha) compared to A1B Scenario (4.248 mt/ha) given higher temperature and drier climate under A2 scenario;
• Rainfed palay yield is projected to be more volatile than irrigated palay yield;• A 5% increase in the ratio of government agriculture expenditure will increase palay yield to
4.279 mt/ha (A2) and 4.309 mt/ha (A1B).
