Plains, show a decrease of about 14% and 7%-17% respectively in wind power density due to global warming over the next
century. This paper focuses on a smaller grid size of 10 km x 10 km to concentrate on a specific wind farm in Pililla, Rizal,
Philippines which is considered as a commercially feasible site by wind developers. (Source: Wind Energy Projection for the
Philippines based on Climate Change Modeling - ScienceDirect)

The Philippines is exposed to different types of hazards, including climate-related threats such as typhoons and extreme
rainfall. Without drastic reductions in GHG emissions, these threats can potentially become even more destructive in the
coming years, around the time nuclear plants would start being operational. This is not to mention other natural hazards
to which the country is exposed, especially earthquakes as it is situated right along the Pacific Ring of Fire.
It must be remembered that the 2011 Fukushima nuclear disaster in Japan occurred largely because of an earthquake and
tsunami. Lessons must also be learned from the case of the BNPP, which was ridiculously overpriced yet was filled with so
many technical and financial issues that made it unideal to be operationalized.
With its high vulnerability to worsening climate change impacts and other natural risks, making the Philippines dependent
on nuclear power puts many communities at high risk to the impacts of a potential disaster.
Supporters of nuclear energy have still not presented a clear-cut solution to the problem of safely disposing radioactive
waste; not even developed nations have truly figured this out. Despite the frequent suggestion for disposing of used
nuclear fuel deep underground, there is currently no such licensed geological repository. This means that the radioactive
waste currently awaiting disposal presents a high risk of leaking radiation and other harmful impacts that can pose serious
risks to human health and the environment. (Source: [OPINION] Should the Philippines develop nuclear energy?

Congestion along Epifanio de Los Santos Avenue (EDSA) is nothing short of iconic. Tales of cars spending
hours on the hot concrete while pedestrians swarm its sides create understandable apprehension. With the EDSA
Greenways Project, however, new ground is being covered.
The Greenways Project aims to upgrade existing pedestrian facilities through covered and elevated
walkways near main transit stations. Currently, the EDSA pedestrian experience is not only unpleasant but
oftentimes unsafe. However, walkways near the Balintawak, Cubao, Guadalupe, and Taft mass transit stations not
only protect pedestrians but encourage the use of public transit as well. (Source: Php 4T Infrastructure Projects to

11 million families lack access to clean water
Helen Flores – The Philippine Star
March 21, 2023 | 12:00 AM
MANILA, Philippines — About 11 million Filipino families still have no access to clean water, according to the National
Water Resources Board (NWRB).
Speaking at the Laging Handa public briefing yesterday, NWRB executive director Sevillo David noted these families get
water from “unsafe” sources such as deep wells, springs, rivers, lakes and rainwater.
David’s statement comes as the Philippines and other countries mark World Water Day on March 22.
Aside from water, David said sanitation also remains a problem in the country as many families still practice open
defecation, risking water contamination and diseases.
According to a recent Philippine Statistics Authority report, a total of 53,066 Filipinos died between 2010 and 2019 due
to water-borne diseases such as typhoid and paratyphoid fever, bloody diarrhea, cholera, viral hepatitis and leptospirosis.

MANILA, Philippines — The Philippines must prepare for the worsening effects of climate change, such as sea level rise and
hotter weather already affecting the country, according to Secretary Renato Solidum Jr. of the Department of Science and
Technology (DOST). In an interview with “The Chiefs” aired on Cignal TV’s One News last Tuesday night, Solidum stressed
that global warming of 1.5 degrees Celsius has dire effects on one of the most at-risk countries from the climate crisis.
Solidum urged the public to conserve water even before the onset of El Niño to be prepared for its adverse effects.
“Overall, there will be decrease in rainfall in various parts of the Philippines. We should conserve water, hopefully,
conserve electricity because scarcity in water affects our beverage and power,” he added.
Solidum said that before El Niño arrives, the country may still expect stronger rains on its western side due to the
southwest monsoon. (Source: ‘Philippines must prepare for worsening effects of climate change’ | Philstar.com)
