    Natural disasters and the Phlippine economy: an evaluation of the impacts of natural disasters on the national and sectoral outputs of the Philippines
    (2009-10) Bael, Shena K.; Sy, Ma. Sheena Jane M.; Tecson, Gwendolyn
    The study on the economic impacts of natural disasters had long been disregarded particularly due to the notion that they yield negative impacts on output. With the recent disasters experienced by the Philippines, there is a need to understand the effects of natural occurrences on the Philippine economy. This paper pioneers on the evaluation of the impacts of natural disasters on Philippine economic outputs. Employing a Blundell-Bond System GMM on a panel data set from 1980 - 2008, we determine the short and long run effects of natural disasters on national and regional GDP and sectoral outputs. It was found that natural disasters have different impacts depending on their type and the measure used. The number of climatic disaster occurrences . increases output in the short run and decreases it in the long run. The reverse is true for the number of geologic disaster occurrences. Disasters whose impacts are directed to people tend to decrease output while those whose impacts are directed on physical capital generally raise output. The Philippine Agriculture, Fishery and Forestry sector is the most unresponsive to the long run effects of natural disasters. Among the three island groups, Luzon, which experiences the most number of disaster occurrences, was found to be the most vulnerable.

    Addressing household vulnerability to climate change: identifying factors affecting residential location choices in flood-hazard zones
    (2010-04) Rivera, Theresa C.; Yu, James Byron P.; Balisacan, Arsenio M.
    Researchers in this study look at theories on residential location choice to determine and analyze factors that affect where a household chooses to locate.. In the City of Marikina, where the study is conducted, two comparable locations are chosen, one is a flood-hazard zone and one is a non-flood-hazard zone. With original data gathered, the focus of the research is to determine those factors that affect a household's vulnerability to greater and more severe incidences of flooding caused by climate change. The research uses a probit model with data gathered consisting of household characteristics, local characteristics, and information-related characteristics. The purpose of this study is to establish factors that may be targeted by improved policy by the country's adaptation efforts concerning climate change

    Impact of climate change on Philippine rice production
    (2007-10) Archita, Ara
    The issue of climate change has been in the center of the global arena for the last decades. Agriculture, where temperature is a significant determinant, becomes vulnerable if permanent changes in climate patterns take place. As such, this paper attempts to quantify the impact of climate change in Philippine agriculture using a time series data from 1980- 2002 of palay from the top producing rice regions of Cagayan Valley, Central Luzon, Bicol and Western Visayas through the widely used method of production function. The estimation uses production output as means to measure the impact brought about by climate changes. Through the use of the production function approach, the volume of rice output is regressed against climate variables and other inputs of production. Results show that the changes seen in climate patterns over the last two decades have augmented rice production for both irrigated and non-irrigated farmlands. However, the marginal increase in output decreases as temperature continuous to warm up. Moreover, the effects of rainfall differ from irrigated and non-irrigated farmlands. Results show that precipitation is a significant factor in determining the volume of rice production only in non-irrigated farmlands during the first semester. In addition, results show that soil quality and socio-economic variable plays a significant role in rice production. As such, government policies should be geared towards proper mitigation to address the consequences of increasing temperature brings to rice production.

    The socio-economic determinants of the adaptability of rural communities to climate change
    (2009-03) Eleazar, Erik Jan; Pico, Nathan Michael
    The purpose of this study is to identify. the determinants of adaptation in rural communities. This study aims to answer the following question: Is there a correlation between literacy and adaptation to climate shocks? A sample size of around 200 farmers in the vicinity of the Jalaur river system in Panay, lloilo was surveyed. Subjects from various altitudes were taken. Variation of incomes expressed as a percentage is regressed on several explanatory variables including age, gender> family size, farm size, literacy, amount of external credit availed, and the like. Literacy and access to credit are interacted to express the view that access to credit is a channel for literacy to express itself in terms of rural income.

    How vulnerable are Philippine provinces to severe climatic events?
    (2014-04) Cabillos, Justin Ann L.; Rapanan, Lara Loudine N.
    Based on several researches, Philippines is among the top countries that are vulnerable to climate change and extreme weather disturbances. Studies on vulnerability and its determinants gained popularity as the trend in climate change research shifted to a vulnerability-led approach. With the objective of ranking Philippine provinces" relative vulnerability, this paper sets out to determine the factors significantly affecting climate change. The zero-inflated Poisson regression model was used to determine the provinces which are most and least vulnerable to typhoons, based on exposure, sensitivity, and adaptive capacity variables such as projected population, projected population density, coastal areas, location variables, human development index, internal revenue allotment, and total income. The results generally mirrored the expected out come exposure and sensitivity variables had a positive impact on vulnerability, while adaptive capacity variables had a negative impact. The results were also used to enumerate policy implication to further improve the provinces. then eventually the country's, regulations
