GIS-aided Biophysical Characterization of Southern Leyte Landscape in Relation to Landslide Occurrences
By Beatriz C. Jadina

This study was conducted in Southern Leyte to characterize its biophysical attributes, identify factors influencing landslide occurrences, develop a landslide database, and present recommendations for suitable land use. The major attributes of the province that were mapped using geospatial technologies (geographic information system, global positioning system, and remote sensing) were rock formations and fault lines, seismic occurrences, slope characteristics, elevation, soil series, vegetation/land use, and rainfall characteristics. Some soil properties of the landslide areas were also determined.

The highest frequency (21%) of landslide occurrences in Southern Leyte was observed in Miocene–andesitic, basaltic, dacitic flows, and breccia geologic formation which is associated with the Leyte segment of the Philippine Fault. It occurred at angles greater than 18° and was at the highest frequency (54%) at angles greater than 50° in both concave and convex slope curvatures.

Forest cover in Southern Leyte decreased from 53 percent in 1954 to 38 percent in 1992—a 15 percent drop in almost four decades. This further decreased to 14 percent in 2010, a 24 percent decline in approximately two decades since 1992. Current vegetation is dominated by cultivated crops, coconut, and abaca. The province is mapped as slightly suitable (36%) to moderately suitable (51%), to suitable (13%) for coconut and abaca production. Slightly suitable areas are those found at higher elevation (> 600 meters above sea level) and steep slopes (> 50°), while those suitable are found at lower elevations and gentle slopes.

Impacts of Cyclone Nargis on Livelihood, Food Security and the Agriculture Sector in Myanmar
By Khin Oo and Theingi Myint

Nowadays, international and regional institutions dedicated to research, training, and extension activities in disaster-prone
countries are emerging. Many contemporary approaches to risk management and reduction, now being discussed and advocated at the international level, have grown out of disaster reduction research and application by developing country researchers and institutions. Natural catastrophes and disasters destroy fixed assets and physical capitals, interrupt production and trade, and divert and deplete savings as well as public and private investments. More than the damage to a country’s economy, the proportion of the land area exposed to a hazard determines the severity of a disaster risk.

Climate change, with its impact on agriculture, is emerging as one of the most significant development issues in the region. Climate change, among others, could alter temperature and precipitation regimes over major agricultural production regions; the frequency and intensity of extreme events – typhoon, floods, and droughts; average sea level; and incidence of pests and diseases. Moreover, agriculture is vulnerable to the impacts arising from global efforts to mitigate greenhouse gases (GHGs) which are likely to affect production costs and income opportunities. Furthermore, climate change, combined with the increasing demand for food, feeds, fibre, and fuel, has the potential to irreversibly damage the natural resource base on which agriculture depends, with significant consequences for food insecurity (IAASTD 2009). Thus, the relationship between climate change and agriculture is two-way: agriculture significantly contributes to climate change and climate change, in general, adversely affects agriculture.

Thus, it is becoming extremely important to put forward discourses on climate change and agriculture in Southeast Asia within the framework of the sector’s role in meeting the objectives of developing countries for food security and sustainable development. This report is among the series of publications that APAN and SEARCA committed as a part of knowledge stocktaking on climate change in Asia and the Pacific. This report aims to identify the current issues and challenges in the agriculture sector at the national and sub-regional levels by providing information on the anticipated impacts of climate change on agriculture and food security in the region, and on the ecosystems and communities most affected or most vulnerable. The current issues and challenges that hinder the strengthening of the ability to cope with climate change and its impacts are identified at the sub-regional and national levels.

Socioeconomics of Climate Change in the Philippines: A Literature Synthesis (1990-2010)
By Asa Jose Sajise, Mercedita Sombilla, and Rico Ancog

Introduction and Framework of Analysis

According to the Initial Communication of the Philippines, the Philippines is among the first countries to respond to the challenge of the climate change phenomenon. As early as May 8, 1991, the Philippine government had created the Inter-agency Committee on Climate Change (IACCC) by virtue of Administrative Order No. 220. Since then, several initiatives such as action-oriented programs and policies have followed to address climate change. Recently, the Philippine government established the Philippine Climate Change Commission by virtue of the Philippine Climate Change Act of 2009 (Republic Act (RA) 9729), which was signed into law on October 23, 2009. The Commission is tasked, among other things, to formulate and implement plans for the country to better respond to natural disasters. Even at the local government level, proactive Local Government Units (LGUs) like the Province of Albay and the City of Sorsogon have initiated programs and policies to address climate change.

While we have made headway in the science and prediction of events related to climate change, there have been few socio-economic literatures on climate change in the Philippines. We have yet to document more extensively the processes and dynamics of human behavior and choices as affected by climate change. How do people autonomously adapt to climate change?
