Located in the northwest corner of South America, Ecuador lives up to its name: the equatorial line crosses the country and passes about 25 miles north of Quito. Despite its modest size on a continental scale, the territory brings together an astonishing diversity of landforms, climates, and ecosystems, to the point of often being described as a “microcontinent.” Understanding the geography of Ecuador means following a journey that goes from the Pacific beaches to the dense forests of the Amazon, passing through the snow-capped volcanoes of the Sierra and the isolated Galápagos archipelago.
A Small Country with Extra-Large Geography
Ecuador covers approximately 283,561 km², of which 276,841 km² is land and 6,720 km² is water bodies. Some official figures mention a slightly smaller area (256,370 km²), but in any case, the country remains one of the smallest in South America, though larger than Uruguay, Guyana, Suriname, or French Guiana.
Length in kilometers of the Ecuadorian coastline on the Pacific Ocean.
The extreme points of the territory reflect this spatial dispersion:
– To the north, Ecuador extends to Darwin Island in the Galápagos, and on the mainland, to the mouth of the Matajé River in the province of Esmeraldas;
– To the south, the border with Peru in the Chinchipe canton marks the limit;
– To the west, the farthest point is Fernandina Island in the Galápagos, and on the mainland, the Santa Elena Peninsula near Salinas;
– To the east, the border with Peru in Orellana province completes this framework.
Ecuador features an exceptional altitudinal range, from sea level on the Pacific coast to the summit of Chimborazo volcano at 6,267 m. This volcano is not only the country’s highest point, but its peak holds a unique geographical record: due to the Earth’s equatorial bulge, it is the point on the Earth’s surface farthest from the planet’s center.
The Major Natural Regions
The geography of Ecuador is based on a now-classic division into four major regions:
– La Costa, the Pacific coastal plain in the west;
– La Sierra, the central Andean region;
– The Amazon, or Oriente, which occupies the eastern part of the territory;
– The Galápagos Islands, the oceanic insular region.
The three continental regions stretch from north to south and are separated by the Andes mountain range, which crosses the country forming a spectacular backbone.
| Main Region | Position | Dominant Character |
|---|---|---|
| La Costa | West, coastline | Coastal plain, tropical climate |
| La Sierra | Center, Andes | High mountains, high-altitude valleys |
| The Amazon (Oriente) | East | Tropical rainforest, Andean foothills |
| Galápagos (Archipelago) | 600 miles west | Oceanic volcanic islands |
La Costa: Fertile Plains and Threatened Coastal Forests
La Costa stretches along the Pacific from the Colombian border to that of Peru. It is a broad plain that gradually rises toward the Andean foothills. The coastal provinces include Esmeraldas, Manabí, Los Ríos, Guayas, El Oro, Santo Domingo de los Tsáchilas, and Santa Elena. This coastal strip concentrates some of the country’s most fertile soils, vast agricultural areas, major port cities, and highly fragile coastal ecosystems.
The major rivers originating in the Sierra irrigate the plain before reaching the ocean. The Guayas River system is the most important: its basin covers approximately 40,000 km². The Guayas itself is formed north of Guayaquil by the confluence of the Babahoyo and Daule rivers, then widens southward to form a large estuary around Puná Island. Farther north, the Esmeraldas River, 320 km long, drains a basin of 20,000 km² and flows into the ocean near the city of Esmeraldas.
An Agricultural and Industrial Coastline
La Costa is often described as Ecuador’s “breadbasket.” It contains vast plantations of bananas, cocoa, coffee, and rice. This agricultural potential, however, comes at an ecological cost: approximately 98% of the original coastal forests have disappeared, replaced by pastures and commercial crops. Industrial banana plantations for large export companies occupy a significant place in the landscape, as do rice paddies and livestock operations.
Ecuador’s coastline concentrates the country’s main ports, each playing distinct economic and strategic roles. Guayaquil, the largest city, is a major commercial port and industrial center. Esmeraldas houses the Balao oil terminal, essential for crude oil exports. Manta, another important port, served as a U.S. air base for counter-narcotics operations.
The coast also contains extensive intertidal zones: about 635 km² of intertidal mudflats are recorded, placing the country among the world leaders for this type of habitat, essential for seabirds and coastal protection.
The Last Remnants of the Pacific Equatorial Forest
Despite massive deforestation, a few fragments of natural forest survive in the coastal ranges of Mache-Chindul, Jama-Coaque, and Chongón-Colonche. These massifs harbor an exceptional set of forests: tropical dry, humid, evergreen, foothill cloud forests, and mangroves. The whole is designated as the Pacific Equatorial Forest and is part of the Tumbes-Chocó-Magdalena biodiversity hotspot. Scientists consider it one of the most threatened tropical forests in the world.
Mangroves, although reduced by aquaculture, play a major role in coastal protection against erosion, water filtration, and hosting important biodiversity of fish and birds.
Climate of La Costa: Between Cold Currents and Tropical Heat
The coastal climate is hot year-round, but varies greatly depending on latitude and especially the influence of ocean currents. The presence of the cold Humboldt Current, coming from the south, and the warm Panama Current, coming from the north, creates a play of seasonal contrasts. Broadly, there is a rainy season from December-January to May-June, and a drier, cooler season from June-July to November-December.
Guayaquil receives over 1,260 mm of rain per year, a precipitation level much higher than other Ecuadorian coastal cities.
El Niño events, which occur every two to seven years, disrupt this balance: the waters warm, rainfall increases sharply on the coast and the western slopes of the Andes, causing floods, landslides, and infrastructure damage. Conversely, La Niña phases often bring drier conditions and drought risks.
The Sierra: The Avenue of the Volcanoes
In the center of the country, the Sierra forms a mountainous Andean band centered on the Cordillera of the Andes. This region occupies about a quarter of the national territory and concentrates a large part of the cities and infrastructure. It includes the provinces of Carchi, Imbabura, Pichincha, Cotopaxi, Tungurahua, Chimborazo, Bolívar, Cañar, Azuay, and Loja.
The Ecuadorian Andes consist of two major parallel ranges, the Cordillera Occidental to the west and the Cordillera Oriental (or Real) to the east. To the north, a third intermediate alignment exists, giving the whole a complex S-shape. Between these ranges, a series of high plateaus and intramontane valleys form an inhabited corridor that geographers call the inter-Andean valley.
Spectacular Volcanic Relief
The Sierra is one of the regions of the world with the highest density of active and extinct volcanoes. More than thirty notable volcanic peaks are recorded, several exceeding 5,000 m. Among the most iconic:
| Volcano / Peak | Approximate Elevation | Status and Key Features |
|---|---|---|
| Chimborazo | 6,267 m | Inactive, farthest point from Earth’s center |
| Cotopaxi | 5,897 m | Very active, one of the highest active volcanoes in the world |
| Cayambe | 5,790 m | Only snow-capped peak located directly on the equator |
| Antisana | 5,753 m | Technical glacial volcano, surrounded by lagoons |
| Illiniza (Sur) | 5,248 m | Double summit in the Cordillera Occidental |
| Tungurahua | 5,023 m | Active volcano overlooking the thermal town of Baños |
| Pichincha | ~4,784 m | Volcano overlooking Quito, eruptions with ashfall |
| Sangay | >5,000 m | One of the most active volcanoes in the country |
Chimborazo, a glacial massif in the Cordillera Occidental, is particularly emblematic. Located about 60 miles south-southwest of Quito, near the city of Riobamba, it is included in a wildlife reserve aimed at protecting Andean camelids such as the vicuña and llama. Its summit is entirely covered in ice, although the glaciers are receding markedly.
Cotopaxi, a famous volcano in the Cordillera Oriental, is recognizable by its almost perfect conical silhouette and its large glacial crater. Located in a highly visited national park, it is known for eruptions that generate powerful lahars. These mudflows, mixtures of ice, ash, and debris, can travel very long distances in the surrounding valleys, posing a major risk.
Further south, the Tungurahua and Sangay volcanoes remind us of the vigor of Ecuadorian volcanism. The former, overlooking the town of Baños, has experienced intermittent activity since the late 1990s. Sangay, in the UNESCO World Heritage site national park of the same name, has been in near-continuous eruption for decades.
Valleys, Páramos, and Retreating Glaciers
Between the cordilleras, the inter-Andean valley hosts cities such as Quito, Ambato, Riobamba, and Cuenca. The valley floors are often between 2,500 and 3,000 m, with crops of corn, potatoes, quinoa, and barley. The slopes have been largely deforested for centuries for agriculture and livestock, as well as for flower cultivation for export.
In 2008, páramos, high-altitude ecosystems typical of the Andes, covered over 1.46 million hectares in Ecuador.
Above 4,650 m, the peaks enter the nival zone, with permanent snow cover and glaciers. Seven main glaciers are recorded on the volcanoes Antisana, Cotopaxi, Chimborazo, Cayambe, the Ilinizas, El Altar, and Carihuairazo. But these ice masses are retreating rapidly: on average, glacial area has decreased by about 53 to 54% in forty years, and some glaciers, like that of Carihuairazo, have already lost more than 90% of their area. Projections indicate a possible complete disappearance of Ecuadorian glaciers by the end of the century.
Mountain Climate: The Importance of Altitude
The Sierra experiences a climate moderated by altitude, with little variation in temperature by month, but very large differences between day and night. On average, the temperature drops about 1 °C for every 200 m of elevation gain. Days are often sunny in the morning, with frequent afternoon showers.
Several climate zones can be distinguished:
The Ecuadorian Andes present a succession of distinct climatic zones, defined by altitude, with specific temperature and precipitation characteristics.
Temperatures from 20 to 25 °C with abundant rainfall.
Temperatures from 15 to 20 °C and moderate precipitation.
Temperatures from 10 to 15 °C and about 1,000 mm of rain per year. This is the zone of Quito (average 15.6 °C, ~1,500 mm precipitation).
Temperatures from 3 to 9 °C with frequent rain, sleet, and fog.
Temperatures near 0 °C or below, realm of permanent snow and ice.
The wet season generally extends from October to May, with the driest period from June to September. Some sheltered valleys receive barely 500 mm of rain per year, while exposed slopes can accumulate up to 2,500 mm. Cities like Cuenca, located at about 2,500 m, have average temperatures near 14.7 °C and less than 900 mm of annual rainfall.
Andean Cities and Settlement
Quito, the capital and second-largest metropolitan area in the country, is situated at 2,850 m in a narrow valley dominated by the Pichincha volcano. Its location makes it the second-highest capital city in the world. Urban growth, constrained by the terrain, has unfolded lengthwise, creating a city over 30 km from north to south but only a few kilometers wide.
Further south, Cuenca nestles in an Andean basin surrounded by mountains, while cities like Riobamba or Ambato dot the famous “Avenue of the Volcanoes,” a term popularized by Alexander von Humboldt to describe this corridor where snow-capped peaks stretch for nearly 320 km.
The population of the Sierra is largely made up of indigenous Kichwa (or Quichua) peoples, whose communities live from agriculture, livestock, and increasingly, rural or community tourism. Cultural diversity is reflected in the presence of many groups such as the Otavalo, Salasaca, or Saraguro.
Ecuadorian Amazon: A Fragment of Great Forest
East of the Cordillera Real, the terrain drops abruptly toward the Amazonian plains. In less than 100 km, the altitude goes from 4,000–6,000 m to about 500 m, forming a series of hills, terraces, and alluvial plains. This region, called the Amazon or Oriente, covers nearly half of the national surface, even though it represents only 1 to 2% of the entire Amazon basin.
The Amazonian provinces – Sucumbíos, Napo, Orellana, Pastaza, Morona Santiago, Zamora-Chinchipe – are largely covered by tropical rainforest. We can distinguish:
– foothill forests on the Andean slopes, where the gradients are steep and the watercourses torrential;
– terra firme forests on non-flooded, red or reddish-brown lateritic soils;
– seasonally flooded várzea forests;
– nearly permanently flooded forests, known as igapó.
The soils are largely poor, heavily leached by rain, with well-drained oxisols near the Andes and more hydromorphic ultisols in the distant flat areas.
A Hydrographic Network Directed Toward the Amazon
Most of the major rivers of the Oriente originate on the eastern slopes of the Sierra before flowing eastward to join the Amazon system. Among the most important:
The Ecuadorian basin of the Napo covers about 31,400 km², with annual precipitation that can reach 3,800 mm.
All these watercourses eventually feed the Amazon River in Peruvian or Brazilian territory. The importance of this resource is also reflected in national figures: renewable water resources are estimated at 424.4 km³, and agriculture consumes about 81% of freshwater withdrawals.
Climate of the Oriente: “Humid and More Humid”
The Amazonian climate is hot, very humid, and rainy throughout the year. In the western part, average temperatures hover around 25.5 °C, with highs around 30 °C and lows of 23 °C. The plains can experience temperatures above 28 °C.
In some foothill sectors, precipitation exceeds 5,000 mm per year.
Relative humidity remains very high, around 83% during the least rainy periods and close to 90% during the wettest months. Rainfall often falls at regular times, especially in the afternoon, shaping a climate that residents sometimes describe as “humid” and “even more humid.”
Forests, Oil, and Indigenous Peoples
About 38% of Ecuador’s territory remained forested in the mid-2010s, a large portion located in the Oriente. However, the country lost 2.1 million hectares of forest between 1990 and 2020, nearly 14.6% of its cover. The Amazon still contains the best-preserved areas, although deforestation is progressing, driven by agricultural expansion, roads, and oil extraction.
The oil industry, central to the national economy, is mainly located in the provinces of Sucumbíos and Orellana, around cities like Lago Agrio and Coca. Its exploitation has caused major environmental damage (hydrocarbon spills, gas flaring) and conflicts with local communities, particularly related to the construction of pipelines.
The Oriente is also the territory of many indigenous nations: lowland Quechua, Siona, Secoya, Huaorani, Cofán, Shuar, Achuar, Záparo, among others. Several of them still live partly from hunting, fishing, and shifting agriculture, and their territories often overlap with protected areas.
Among these, Yasuní National Park (about one million hectares) and the Cuyabeno Wildlife Reserve (over 600,000 hectares) are often cited as biodiversity hotspots of global importance, with records of diversity per hectare in amphibians, birds, insects, and plants.
The Galápagos: An Isolated Natural Laboratory
Nearly 600 miles west of the continent, the Galápagos Islands constitute the fourth major geographic region of the country. This volcanic archipelago, sitting on the Nazca Plate, includes 18 major islands, several islets, and about a hundred rocks and reefs. The total emerged area is around 7,880 to 8,000 km², scattered over about 45,000 km² of ocean.
Isabela is by far the largest island (4,640 km²) and concentrates several large shield volcanoes, including Wolf, the archipelago’s highest point at 1,707 m. Fernandina, also very active, features a large partially collapsed caldera. Most islands come from a single volcanic edifice, except notably Isabela, formed by the fusion of six volcanoes.
Still Active Volcanism
The Galápagos rest on a hotspot beneath the Nazca Plate, which moves east-southeast at a few centimeters per year. As the plate slides over the mantle plume, new volcanoes emerge in the west, while the oldest islands erode in the east. Eruptions are regularly observed: over 50 have been recorded in the last 200 years, involving at least nine different volcanoes.
Typical relief features include:
– vast collapsed calderas (Fernandina, Sierra Negra);
– rough ‘a‘ā or smooth pāhoehoe lava flows;
– cinder cones, spatter cones, explosion craters;
– lava tubes, coastal cliffs.
The archipelago lies at the junction of three plates (Nazca, Cocos, Pacific) and is partly bordered to the north by the accretion center of the Galápagos Ridge. It rests on a submarine basaltic plateau, connected to the continent by the Carnegie Ridge.
Island Climate: Cold Currents and Alternating Seasons
Although crossed by the equator, the Galápagos do not have a purely tropical climate. The cold Humboldt Current, which flows up the South American coast, along with the subsurface equatorial countercurrent (Cromwell Current), strongly influence air and water temperatures.
Two main seasons stand out:
– the cool and dry season (garúa), from June to November, marked by mists, drizzle, and low clouds, with temperatures of 21–22 °C at low altitude;
– the warm and more humid season, from December to May, with more showers and average temperatures around 25–26 °C.
In the Galápagos archipelago, precipitation varies considerably with altitude and exposure. Coastal areas, like Baltra Island, are often semi-arid. In contrast, higher elevations can capture much more moisture. For example, the Charles Darwin Research Station on Santa Cruz Island records monthly rainfall totals much higher than those on neighboring Baltra Island, illustrating the importance of microclimate effects in the archipelago.
An Oceanic Biodiversity Hotspot
The Galápagos are famous for their endemic fauna: giant tortoises, marine iguanas, flightless cormorants, Darwin’s finches, the Galápagos penguin – the only penguin species living north of the equator – as well as many unique plants, reptiles, and invertebrates. There are about 500 species of native vascular plants, a significant number of which are endemic.
This richness is linked to the archipelago’s isolation, the variability of habitats (arid zones, coastal mangroves, humid highland forests), and marine currents that nourish highly productive waters.
However, the islands are stressed by various pressures: introduced species (rats, goats, invasive plants), population growth (over 30,000 inhabitants), tourism development (over 150,000 annual visitors), waste management, and risks related to maritime traffic.
Climates, Seasons, and Natural Hazards
One of the most striking features of the geography of Ecuador lies in the variety of its climates within a restricted area. On a national scale, the average annual temperature is about 21.7 °C, with an average rainfall estimated at 2,201 mm. But these global figures mask strong contrasts between regions.
A simple rule helps understand the thermal structure: temperature decreases by about 1 °C per 200 m of elevation gain. Thus, in a few hours by road, it is possible to go from humid tropical heat at 30 °C in the coastal plain to a near-autumnal climate of 15 °C in Quito, then to winter-like conditions near 0 °C on the Andean glaciers.
Three Major Continental Climate Zones
On the mainland, the major trends can be summarized as follows:
Ecuador’s coastal region enjoys a tropical climate, marked by a rainy season (generally from December to May-June) and a drier season (June to November). Temperatures are consistently high, often near 30 °C during the day. Its climate is strongly influenced by ocean currents (cold Humboldt and warm Panama) and ENSO phenomena (El Niño / La Niña), leading to great year-to-year variability, including episodes of extreme rainfall during El Niño events.
– The Sierra: temperate high-altitude climate, strongly modulated by elevation. The driest season occurs between June and September, while the October–May period is wetter. Daily temperature ranges are marked: relatively mild sunny mornings and cold nights. Major Andean cities have average annual temperatures below 16 °C.
– The Amazon (Oriente): equatorial rainforest climate, hot and very humid, with rain throughout the year. A slightly less rainy period often occurs between August and December, but there is no true dry season. Temperatures range between 24 and 28 °C, with constantly high humidity.
To grasp these contrasts, some data from representative cities are illuminating:
| City / Islands | Region | Average Temperature (°C) | Annual Rainfall (mm) |
|---|---|---|---|
| Quito | Sierra | 15.6 | ~1,098 to 1,500 |
| Cuenca | Sierra | 14.7 | ~878 |
| Guayaquil | Costa | 26.5 | ~1,263 |
| Manta | Costa | 25.4 | ~254 |
| Machala | Costa | Max. 28.9 | ~489 |
| San Cristóbal (Galápagos) | Insular | 24.8 | ~578 |
These figures highlight the cooler, more variable character of the Sierra, the coastal heat sometimes tempered by aridity, and the mildness of the Galápagos, softened by ocean currents.
Natural Hazards: A Country Under Geological Stress
The position of Ecuador on the Pacific Ring of Fire and at the crossroads of several tectonic plates makes the country particularly exposed to natural hazards. The main natural risks are:
Ecuador is exposed to several major natural hazards. Earthquakes, frequent and sometimes destructive, are linked to the subduction of the Nazca Plate beneath the South American Plate. Volcanism manifests through explosive eruptions, lava flows, pyroclastic flows, and lahars on the many active volcanoes in the Andes and Galápagos. Landslides, favored by steep topography and intense rainfall, are common in the Andes and Oriente. Finally, floods and droughts are accentuated by El Niño (extreme rains) and La Niña (water deficits) events, particularly on the coast and western slopes of the Andes.
Climate variability and rising temperatures since the mid-20th century (about +1.4 °C between 1960 and 2010 on a national scale) amplify these risks. Rains tend to become more intense in the Sierra and Amazon, while some coastal areas like Esmeraldas, Manabí, or Santa Elena could experience a drastic decline in precipitation by mid-century under high-emission scenarios.
Natural Resources, Biodiversity, and Land Use
The geography of Ecuador is not limited to landforms and climates: it also structures the economy and the distribution of ecosystems. Ecuador is considered one of the world’s 17 “megadiverse” countries, with the highest biodiversity per km² on the planet. On a small territory, there are over 16,000 plant species, about 1,600 bird species on the mainland (plus 38 endemic to the Galápagos), over a hundred endemic reptiles, nearly 140 endemic amphibians, and some 6,000 butterfly species.
Land Distribution and Agriculture
About 4.6% of the territory is arable land and 5.6% is permanent crops; the rest (nearly 90%) corresponds to other uses (forests, pastures, urban areas, unproductive surfaces). Forests still covered just over half of the continental territory in the mid-2010s, with about 12.75 million hectares, nearly half of which was primary forest. Mangroves covered nearly 157,000 hectares.
About 75% of land in France is natural spaces, illustrating their importance in the distribution of land uses.
| Type of Land Use | Approximate Share of Territory |
|---|---|
| Arable land | ~4.6% |
| Permanent crops | ~5.6% |
| Other (forests, pastures, etc.) | ~89.8% |
| Forest (2014, mainland) | ~51.2% |
Agriculture varies by region:
– on the Costa: bananas, cocoa, coffee, rice, sugarcane, oil palm, vegetable crops;
– in the Sierra: potatoes, corn, quinoa, wheat, barley, flower crops (roses);
– in the Amazon: pastures, small subsistence crops, perennial crops, as well as clearings linked to livestock.
The main agricultural exports – bananas, fine cocoa, flowers, shrimp, tuna, balsa wood – are largely rooted in the coastal and Andean geography.
A Natural Heritage Under Pressure
Despite this richness, Ecuador has a large number of threatened species: over 2,500 in total, including nearly 170 amphibians, over 100 birds, several dozen mammals and reptiles. About 19 to 20% of the national territory is protected through the National System of Protected Areas (SNAP), which includes national parks, ecological reserves, wildlife refuges, wildlife production reserves, etc. An official target mentions the need to increase this protection to 32% to ensure the conservation of key ecosystems.
Number of hectares covered in 2018 by the Socio Bosque program, just over 2% of Ecuadorian territory.
Despite these efforts, deforestation remains high, especially on the Costa (where only about 30% of the original vegetation is thought to remain), in some Andean areas (about 40%), and to a lesser extent in the Amazon (where nearly 88% of the initial vegetation cover still existed, but is declining). Dry forests, once widespread, now cover only about 8,200 square miles, with a tiny fraction of intact formations.
Cities, Population, and Territorial Organization
The geography of Ecuador also structures the distribution of the population. Out of about 17 to 18 million inhabitants, over 60% live in urban areas. Most major cities are concentrated on the Costa and in the inter-Andean Sierra.
The two dominant metropolises are:
– Guayaquil, largest city and main port, at the heart of the Costa;
– Quito, political capital, in the Sierra.
Together they account for nearly half of the urban population. Behind this duo, medium-sized agglomerations complete the network: Cuenca, Santo Domingo, Ambato, Manta, Machala, Portoviejo, Loja, Ibarra, Esmeraldas, Quevedo, Latacunga, Milagro, Santa Elena, Babahoyo, among others.
Quito and Guayaquil represent the two geographic and economic poles of the country. Quito, located in the high Andean valleys, is oriented inland and toward the volcanoes, while Guayaquil, on the Pacific coast, opens onto the sea and the Guayas plains. This fundamental division has shaped transport networks, economic flows, and forged distinct regional identities.
The Amazon, on the other hand, remains sparsely populated. Its main cities – Lago Agrio, Coca, Tena, Puyo, Macas, Zamora – are small on a national scale and are often connected to the rest of the country by a few main roads and air links. Rivers retain a major logistical importance, especially the Napo.
The Galápagos, finally, have only a population of about 30,000 to 40,000 inhabitants, distributed among the inhabited islands (Santa Cruz, San Cristóbal, Isabela, Floreana, Baltra). The isolation and heritage value of the archipelago require specific management, with a special provincial status and restrictions on residence and economic activities.
Geography at the Heart of Environmental Policies
Ecuador’s geographic diversity implies a complex management of natural resources and risks. The country pioneered by enshrining in its 2008 constitution legally enforceable rights of nature, recognizing ecosystems as subjects of law. This approach is intimately linked to the reality of a territory where the effects of human activities – intensive agriculture, oil extraction, urbanization, dams – are rapidly felt on highly contrasting environments.
National climate policies incorporate precise regional projections: a stronger temperature rise in the Sierra and Amazon, uncertainty about rainfall volumes but an intensification of extreme rains inland, aridification of some coastal sectors, a programmed reduction of Andean glaciers, and sea-level rise threatening low coasts and mangroves.
These issues resonate with human geography: the zones most exposed to flooding are in the coastal plains and river valleys; landslides mostly affect deforested Andean slopes; rising saltwater threatens coastal aquifers; the reduction of glacial meltwater already strains drinking water supply for some Andean cities.
Ecuadorian geography, divided into four distinct regions (Coast, Sierra, Amazon, Galápagos), requires policies adapted to each: protection of remnant forests on the coast, reforestation and soil management in the mountains, defense of indigenous territories and parks in the Amazon, and strict regulation of tourism in the Galápagos.

The geography of Ecuador thus illustrates the paradox of a small state that is both extremely rich in natural environments and subject to intense pressures. From the beaches of the Pacific to the snows of Chimborazo, from the forests of Yasuní to the lava flows of Fernandina, Ecuador condenses within a few hundred miles a diversity that other nations deploy across entire continents. Understanding these landforms, these rivers, these climates, and these ecosystems is to grasp the key to a territory whose future will depend, more than ever, on how it manages to reconcile human development with the preservation of this extraordinary geographical heritage.
