Policy Briefs

SEARCA’s Policy Brief Series discusses a comprehensive analysis of climate change-related issues and provides policy and research recommendations towards sustainable agriculture and natural resource management.

emerging This report aims to fill a need for the latest thinking on climate change adaptation (CCA) in the Asia-Pacific region, thus the members of the Asia Pacific Adaptation Network (APAN)* produced this report titled Emerging Climate Change Adaptation Issues in the Asia-Pacific Region to address pertinent and relevant issues in the region and sub-regions. This report aims to raising awareness and building the capacity of policymakers to deal with CCA.

Flooding has increased in frequency in various parts of the country, causing damage to thousands of households every year. It directly affects communities through damage to livelihood and properties, loss of earning, and health hazards. Households dependent on agriculture for livelihood are particularly vulnerable because of the negative impact of flooding to productivity.

Damage assessments following flood events are regularly done to determine extent of loss and to identify critical areas for intervention. However, these are often macroscale assessments, which
do not necessarily generate information that could be useful for policymaking. At the municipal level, planning for disaster mitigation and adaptation strategies are devolved and should be operationalized. This study sought to determine microscale damage estimates of the largest flood event in the history of Jabonga, in Agusan del Norte, in southern Philippines. Jabonga is a lakeside municipality adjacent to Lake Mainit, the fourth largest lake in the Philippines.

Data and Method

The municipality of Jabonga is located in Caraga Region, which was classified as part of the poorest cluster in 2009. Thirty-nine percent (39%) of the region’s total employment in 2010 is in the agriculture sector (Bureau of Agricultural Statistics 2011). The agriculture dependency of the municipality is higher than the regional rate, with 60 percent of the population either partly or fully dependent on farming. Seven of the municipality’s 15 barangays are prone to flooding. Since 2005, between 914 to 2,909 households in Jabonga have been annually affected by floods. On the average, farms in hazard zones are inundated for 32 days, while residential areas are flooded for 30 days. During the flooding event in the first quarter of 2011, 71 percent of the houses in the flood hazard zone sank, and the livelihood of 61 percent of the household population was affected.

Soil and water resources in the world are currently under severe pressure due to human intervention and the changing of runoff patterns caused by climate and land use changes. Population growth and human activities have accelerated the speed of land use change, that in turn  affect hydrological processes. In addition, climate change may affect many aspects of natural  ecosystems. Hence, understanding of impacts of climate change and land use change on hydrological  conditions is essential to enable more efficient soil and water resources development. In the same light, Srepok catchment, whichis situated in the Central Highlands of Vietnam, is presently being challenged by many critical  issues for soil and water resources management in the Srepok river basin (Government of Vietnam 2006). However, non-linear relationships, multiple causation, lack of mechanistic understanding, and lag effects, together, limit the ability to diagnose causes. As this information is important for land use planning and water resources management, it is necessary to quantify the extent to which land use change and climate variability influence the hydrological conditions.

Agricultural Innovation: Options for Appropriate Technologies in Responding to Climate Change
SEARCA-APAN Policy Brief

Agriculture is a key sector providing economic and social development in Southeast Asian countries, where a majority of the region’s population depend on agricultural production as a main source of household income. The implication of global environmental change has extended the agricultural agenda to respond to the drivers of climate change—in the context where agriculture is both a contributor to greenhouse gas (GHG) emissions and a possible mitigating factor through the adjustment of practices and the adoption of new technologies.

The role of agriculture in climate change is better appreciated in relation to the value agriculture contributes to the global economy. The 2010 World Development Report, drawing on analysis from the Intergovernmental Panel on Climate Change, calculates that agriculture directly accounts for 14 percent of global GHG emissions in CO2 equivalent and indirectly accounts for another 17 percent of emissions from land use and conversion for crops and pasture. In contrast, the contribution of agriculture to the global GDP at four percent suggests that worldwide agricultural activity is highly GHG intensive (Lybbert and Sumner 2010).
