The Philippines, officially the Republic of the Philippines, is an archipelagic country in Southeast Asia. In the western Pacific Ocean, it consists of 7,641 islands, with a total area of roughly 300,000 square kilometers, which are broadly categorized in three main geographical divisions from north to south: Luzon, Visayas, and Mindanao. The Philippines is bounded by the South China Sea to the west, the Philippine Sea to the east, and the Celebes Sea to the south. It shares maritime borders with Taiwan to the north, Japan to the northeast, Palau to the east and southeast, Indonesia to the south, Malaysia to the southwest, Vietnam to the west, and China to the northwest. It is the world's twelfth-most-populous country, with diverse ethnicities and cultures. Manila is the country's capital, and its most populated city is Quezon City. Both are within Metro Manila.

The eleven largest islands contain 95% of the total land area. The largest of these islands is Luzon at about 105,000 square kilometers (40,541 sq mi). The next largest island is Mindanao at about 95,000 square kilometers (36,680 sq mi). The archipelago is around 800 kilometers (500 mi) from the Asian mainland and is located between Taiwan and Borneo.
The economy of the Philippines is an emerging market, and considered as a newly industrialized country in the Asia-Pacific region. In 2024, the Philippine economy is estimated to be at ₱26.55 trillion, making it the world's 32nd largest by nominal GDP and 13th largest in Asia according to the International Monetary Fund.
Laguna de Bay, also known as Laguna Lake and alternatively spelled "Laguna de Bae", is the largest lake in the Philippines. It is located southeast of Metro Manila, between the provinces of Laguna to the south and Rizal to the north. A freshwater lake, it has a surface area of 911–949 km2, with an average depth of about 2.8 meters and an elevation of about one meter above sea level. The lake is shaped like a crow's foot, with two peninsulas jutting out from the northern shore and filling the large volcanic Laguna Caldera. In the middle of the lake is the large island of Talim.
The Pasig River is a water body in the Philippines that connects Laguna de Bay to Manila Bay. Stretching for 25.2 kilometers (15.7 mi), it bisects the Philippine capital of Manila and its surrounding urban area into northern and southern halves. Its major tributaries are the Marikina River and San Juan River. The total drainage basin of the Pasig River, including the basin of Laguna de Bay, covers 4,678 square kilometers (1,806 sq mi).
Mount Apo, also known locally as Apo Sandawa, is a large solfataric, dormant stratovolcano on the island of Mindanao, Philippines. With an elevation of 2,954 meters (9,692 ft) above sea level, it is the highest-mountain in the Philippine Archipelago, Mindanao and 24th-highest peak of an island on Earth. Located on the tripartite border of Davao City and Davao del Sur in the Davao Region, and Cotabato in Soccsksargen, Mount Apo is the most-prominent mountain in the Philippines. The peak overlooks from Davao City 45 kilometers (28 mi) to the northeast, Digos 25 kilometers (16 mi) to the southeast, and Kidapawan 20 kilometers (12 mi) to the west. It is a protected area and a Natural Park of the Philippines.

Central Canada is a Canadian region consisting of Ontario and Quebec, the largest and most populous provinces of the country. Geographically, they are not at the centre of Canada but instead overlap with Eastern Canada toward the east. Because of their large populations, Ontario and Quebec have traditionally held a significant amount of political power in Canada, leading to some amount of resentment from other regions of the country. Before Confederation, the term "Canada" specifically referred to Central Canada. Today, the term "Central Canada" is less often used than the names of the individual provinces.
Sibuyan is a crescent-shaped island, the second largest in an archipelago comprising Romblon Province, Philippines. Located in the namesake Sibuyan Sea, it has an area of 445 square kilometres (172 sq mi) and has a total population of 62,815, as of the 2020 census. The island has two prominent peaks, the highest is Mount Guiting-Guiting, with an elevation of 2,058 metres (6,752 ft), followed by Mount Nailog, which is 789 metres (2,589 ft) high. The people speak the Sibuyanon dialect of Romblomanon, a Visayan language.
The Rio Grande de Mindanao, also known as the Mindanao River, is the second-largest river system in the Philippines. Located on the southern island of Mindanao, with a total drainage area of 23,169 km2 (8,946 sq mi), draining the majority of the central and eastern portion of the island, and a total length of approximately 373 km (232 mi). It is an important transportation artery, used mainly in transporting agricultural products and, formerly, timber.
The Department of Environment and Natural Resources, abbreviated as DENR, is the executive department of the Philippine government responsible for the conservation, management, development, and proper use of the country’s environment in natural resources, specifically forest and grazing lands, mineral resources, including those in reservation and watershed areas, and lands of the public domain, as well as the licensing and regulation of all natural resources as may be provided for by law in order to ensure equitable sharing of the benefits derived therefrom for the welfare of the present and future generations of Filipinos.
Today, environmental problems in the Philippines include pollution, mining and logging, deforestation, threats to environmental activists, dynamite fishing, landslides, coastal erosion, biodiversity loss, extinction, global warming and climate change. Due to the paucity of extant documents, a complete history of land use in the archipelago remains unwritten. However, relevant data shows destructive land use increased significantly in the eighteenth century when Spanish colonialism enhanced its extraction of the archipelago's resources for the early modern global market. The Philippines is projected to be one of the most vulnerable countries to the impacts of climate change, which would exacerbate weather extremes. As the Philippines lies on the Pacific Ring of Fire, it is prone to natural disasters, like earthquakes, typhoons, and volcanic eruptions. In 2021, the Philippines ranked the fourth most affected country from "weather-related loss events", partly due to the close proximity of major infrastructure and residential areas to the coast and unreliable government support. One of the most devastating typhoons to hit the archipelago was Typhoon Haiyan, known locally as Yolanda, in 2013 that killed 6,300 people and left 28,689 injured. Congress passed the Clean Air Act of 1999, the Philippine Clean Water Act of 2004, the Climate Change Act of 2009 to address environmental issues. The country is also a signatory to the Paris Agreement. However, research has found that outside of cities, the general public doesn't feel equally informed. Environmental activists and land defenders, consisting mostly of Indigenous communities who have been attempting to bring attention to the environmental issues in the country have been met with violence or murder. As a result, the Philippines has been ranked one of the most dangerous places in the world for environmental activists. It also has one of the highest percentages of climate change denialists in the world.
The Agus River is a river that flows for 36.5 kilometres (22.7 mi) from Lake Lanao to Iligan Bay, Philippines. It cuts through the provinces of Lanao del Sur and Lanao del Norte. Settlements along the banks of the river include the city of Marawi, the municipality of Linamon, and the city of Iligan. It separates into two channels as it drains to Iligan Bay; one goes over the Maria Cristina Falls, while the other supplies the Tinago Falls. The river descends for about 2,200 feet (670 m) from its source as it flows for 21 miles (34 km) before draining to the sea. The river is relatively shallow as it is only 4 feet (1.2 m) deep in some areas. The Agus River's watershed spans about 11,320.00 hectares. It has a discharge of about 10 cubic metres per second (350 cu ft/s) and flows from a narrow depression off the northwestern rim of the lake and flows over a basalt rock formation. The canyon carved by the river suggests a short erosional period.
The Philippines' water supply system dates back to 1946, after the country declared independence. Government agencies, local institutions, non-government organizations, and other corporations are primarily in charge of the operation and administration of water supply and sanitation in the country.
In 2023, official government statistics reported that the Philippines had a poverty rate of 15.5%,, significantly lower than the 49.2 percent recorded in 1985 through years of government poverty reduction efforts. From 2018 to 2021, an estimated 2.3 million Filipinos fell into poverty amid the economic recession caused by the COVID-19 pandemic.

The Lower Agno Watershed Forest Reserve is a Philippine protected area that straddles the Cordillera and Ilocos regions encompassing land from the provinces of Benguet and Pangasinan. Operated by the Lower Agno WFR Protected Area Management Board under the Department of Environment and Natural Resources, Lower Agno follows the Agno River corridor from the northern villages of Itogon to just north of the municipalities of San Manuel and San Nicolas. The reserve also known as the San Roque Watershed protects the mid-Agno River basin with its meandering river and short tributaries in a pine-forested mountainous terrain at the southern end of the Cordillera Central, around 30 kilometres (19 mi) southeast of Baguio. It is located in an important mining district and includes the reservoir of the San Roque Dam, the largest dam in the country and the prime source of water, hydropower and irrigation for surrounding regions in Luzon.
