South Korea's countryside occupies approximately 64 percent of the national territory, though only 18 percent of the population lives outside metropolitan areas as of 2023. The Korean Peninsula's southern portion rises sharply from coastal plains through forested mountain ranges that constitute 70 percent of the land surface. The Taebaek Mountains run north-south along the eastern spine from the DMZ to Busan, creating an asymmetric topography where the eastern slope drops steeply to the East Sea while western slopes descend gradually toward the Yellow Sea through successive ridgelines and river valleys. The Sobaek Mountains branch southwest from the Taebaek range near the 38th parallel, dividing the peninsula's interior watersheds.
Agricultural land covers 16,460 square kilometers, concentrated in river basins and coastal plains where irrigation systems developed over thirteen centuries. The Han River basin north of Seoul, the Nakdong River valley between Daegu and Busan, the Geum River plains around Daejeon, and the Yeongsan River lowlands near Gwangju contain South Korea's primary rice cultivation zones. Terraced paddies climb hillsides throughout Jeollanam-do and Gyeongsangbuk-do provinces where flat land proves insufficient. The Honam Plain in Jeollabuk-do province, stretching from Jeonju to the Yellow Sea coast, forms the largest continuous agricultural region, producing 30 percent of South Korea's rice harvest from 1,200 square kilometers of paddies.
Rice cultivation occupies 7,560 square kilometers during the growing season from May through October, though this represents a 45 percent decline from 1990 levels as agricultural consolidation and land conversion continue. South Korea achieved rice self-sufficiency at 92 percent in 2022, importing the remainder under World Trade Organization minimum access agreements. Single-crop rice farming dominates despite government programs encouraging crop diversification. Winter barley cultivation once covered fallow rice paddies throughout the southern provinces but declined to 290 square kilometers by 2020 as wheat imports replaced domestic grain production.
Greenhouse agriculture concentrates in Gyeonggi-do and Jeollanam-do provinces, where 54,000 hectares of climate-controlled facilities produce tomatoes, cucumbers, strawberries, and peppers year-round. The town of Nonsan in Chungcheongnam-do contains South Korea's largest strawberry cultivation zone, with 1,800 hectares of greenhouses producing 25,000 tons annually. Gochang County in Jeollabuk-do specializes in watermelon cultivation on 4,200 hectares, marketing the crop through a geographical indication system established in 2004. Highland vegetable farming occurs above 600 meters elevation in Gangwon-do province, where summer temperatures remain suitable for cabbage, radish, and potato cultivation while lowland regions exceed optimal growing temperatures.
Orchard agriculture occupies 1,580 square kilometers, concentrated on southern and eastern slopes with drainage and sun exposure. Apple cultivation centers in Gyeongsangbuk-do province around Daegu and Yeongju, where 300 millimeters of precipitation falls between May and September and winter temperatures drop below freezing for dormancy requirements. Chungju in Chungcheongbuk-do province produces apples on 2,100 hectares at elevations between 200 and 400 meters. Pear orchards concentrate in Naju, Jeollanam-do, where sandy loam soils and 1,200 millimeters annual precipitation support 3,400 hectares producing Asian pears marketed as Naju-bae under geographical indication since 2006.
Jeju Island contains 21,000 hectares of mandarin orange orchards concentrated on the southern and eastern coastal slopes below 200 meters elevation, where maritime climate moderates winter temperatures and volcanic soils provide drainage. Hallasan's 1,947-meter peak creates orographic precipitation exceeding 1,800 millimeters annually on southern slopes while northern areas receive 1,200 millimeters. Seogwipo City on Jeju's southern coast produces 90,000 tons of mandarin oranges annually between October and February, representing 95 percent of South Korean citrus production. Jeju's orchard landscape includes stone walls constructed from volcanic basalt to protect trees from typhoon winds averaging 140 kilometers per hour during September and October.
Ginseng cultivation occupies specialized sites in Geumsan County, Chungcheongnam-do, where 1,200 hectares under shade structures produce Panax ginseng requiring four to six years before harvest. Geumsan's ginseng market, operating since 1561, processes 80 percent of South Korean ginseng production. Fields rotate ginseng with other crops on 10-year cycles because the plant depletes specific soil nutrients. Black plastic shade cloth covering ginseng fields creates distinctive striped patterns across Geumsan's hillsides. Punggi in Gyeongsangbuk-do province cultivates ginseng on 400 hectares using traditional straw shade structures, maintaining methods documented in Joseon Dynasty agricultural texts.
Tea cultivation persists in Jeollanam-do province's southern counties, where winter temperatures rarely drop below minus 5 degrees Celsius, allowing Camellia sinensis survival. Boseong County contains 6 square kilometers of tea plantations on hillsides between 100 and 300 meters elevation, producing 40 percent of South Korean green tea. Terraced tea fields climb slopes at Daehan Dawon plantation, where rows follow contour lines visible from provincial highway 18. Hadong County in Gyeongsangnam-do province cultivates tea on 800 hectares along the Seomjin River valley, claiming cultivation history extending to 828 CE when seeds arrived from Tang Dynasty China.
Forestland covers 63,000 square kilometers, representing 63 percent of South Korea's total area, though forest composition reflects 20th-century reforestation following deforestation during Japanese colonial period and Korean War. The government planted 10 billion trees between 1973 and 1987 under President Park Chung-hee's national reforestation program, concentrating on fast-growing species including Korean pine, larch, and oak. Current forests contain 35 percent coniferous species, 27 percent deciduous broadleaf, and 38 percent mixed stands. Natural old-growth forest survives only in temple grounds and remote mountain valleys, totaling less than 3 percent of forested area.
Mountain villages dot valleys throughout the Taebaek and Sobaek ranges, though population decline reduced many to fewer than 100 residents. Inje County in Gangwon-do province contains 150 administrative villages across 1,646 square kilometers, yielding population density of 15 persons per square kilometer compared to South Korea's national average of 517. Villages typically cluster where tributary streams meet larger rivers, with south-facing slopes preferred for sunlight and north slopes reserved for fuel wood collection. Traditional village layouts position ancestral shrines on elevated northern ground, residential structures on mid-slopes, and agricultural fields along watercourses.
Hanok architecture using timber frames, clay walls, and ceramic tile roofs characterizes older rural structures, though concrete construction replaced traditional methods after 1970. Hahoe Folk Village in Andong preserves 127 hanok structures housing 230 residents in a village layout dating to the 16th century. The village occupies a peninsula formed by a 180-degree bend in the Nakdong River, with tile-roofed yangban aristocratic houses on higher ground and thatched commoner houses below. Yangdong Folk Village near Gyeongju contains 160 structures across 1.89 square kilometers, maintaining spatial hierarchy where the Gyeongju Son clan and Yeogang Yi clan built houses according to social status over five centuries.
Rural depopulation accelerated after 1970 when industrial development concentrated in Seoul, Busan, and southeastern manufacturing zones. South Korea's rural population declined from 44 percent of the total in 1970 to 18 percent in 2020. Jeollanam-do province's population decreased from 3.3 million in 1970 to 1.86 million in 2020 despite stable total national population. Abandoned farmhouses appear throughout Gyeongsangbuk-do and Gangwon-do provinces, where 47,000 empty rural houses existed in 2021. The government's Return to Farming and Fishing Program, initiated in 2009, provides loans and training to urban residents relocating to rural areas, though annual participants number only 12,000.
Agricultural villages now contain Korea's oldest population demographics, with 49 percent of farm household heads aged 65 or older in 2020. Jeollanam-do province's Sinan County recorded median age of 61 years in 2020, compared to national median of 43. Farm household size decreased from 4.6 persons in 1990 to 2.4 in 2020. Mechanization replaced hand labor as rural wages exceeded urban wages after 2010, with agricultural workers earning average 52,000 won daily for seasonal work compared to 48,000 won in construction. Rice transplanting machines operate on 97 percent of paddy area, and combine harvesters process 98 percent of rice harvest.
Livestock farming concentrates in Jeollabuk-do, Chungcheongbuk-do, and Gyeonggi-do provinces, separated from residential zones after odor complaints and environmental regulations tightened. South Korea contained 3.3 million cattle in 2021, including 1.8 million Hanwoo beef cattle and 420,000 dairy cattle. Hongseong County in Chungcheongnam-do specializes in Hanwoo breeding, maintaining 160,000 cattle on 4,200 farms across 444 square kilometers. Individual farm size averages 38 cattle, though facilities housing 200-500 animals concentrate near feed mills and processing plants.
Pig farming totaled 11.2 million animals in 2021, concentrated in Jeollabuk-do and Chungcheongnam-do provinces where 43 percent of national inventory resides. African Swine Fever outbreaks beginning September 2019 required culling 400,000 pigs within 10 kilometers of the DMZ in Gyeonggi-do and Gangwon-do provinces. The government imposed movement restrictions and constructed wild boar fencing along 488 kilometers of roads near the DMZ. Livestock burial sites from foot-and-mouth disease outbreaks in 2010-2011, when 3.5 million animals were culled, remain visible as vegetated mounds across Gyeonggi-do and Chungcheongbuk-do provinces.
Poultry operations concentrate in Jeollabuk-do and Gyeongsangnam-do provinces, producing 14 billion eggs annually from 72 million laying hens. Broiler chicken production totals 950 million birds annually, housed in facilities averaging 30,000 birds per operation. Avian influenza outbreaks during winter migration seasons require periodic culling, with 37 million poultry destroyed during the 2016-2017 outbreak. Poultry operations must maintain 3-kilometer separation from migratory bird habitats following 2014 regulations, restricting coastal locations near wetlands.
Fishing villages line South Korea's 12,743 kilometers of coastline, though employment in marine fishing declined from 220,000 persons in 1990 to 94,000 in 2020. The Yellow Sea coast contains mudflat zones extending 5 kilometers offshore at low tide, where hand-gathering of clams, oysters, and crabs employs 18,000 persons, 82 percent female and 71 percent over age 60. Taean County in Chungcheongnam-do contains 23 fishing villages along 210 kilometers of irregular coastline, where spring tides expose 47 square kilometers of mudflats. Traditional wooden fishing boats called baetdegi, measuring 4 to 6 meters, access shallow mudflat channels.
The East Sea coast supports squid fishing during May through November, with ports at Sokcho, Pohang, and Ulleungdo processing catches. Jumunjin Port in Gangneung operates 340 squid fishing vessels using automated jigging machines with LED lights attracting squid from depths of 100 to 300 meters. Port facilities include ice-making plants producing 200 tons daily during peak season. Dried squid production occurs in coastal villages where squid split lengthwise hang on racks for 3 to 5 days, creating distinctive drying yards visible in satellite imagery.
Oyster cultivation concentrates in Tongyeong and Geoje areas of Gyeongsangnam-do province, where sheltered bays provide calm water for suspended culture. Oyster farmers attach spat collectors to floating rafts in April, harvesting market-size oysters after 18 months. Tongyeong produced 24,000 tons of oysters from 800 hectares of sea surface in 2020. Oyster farms create geometric patterns of white floats marking cultivation areas. Seaweed farming for gim (laver) production occurs in shallow coastal waters of Jeollanam-do province, where nets suspended between posts harvest Pyropia yezoensis during winter months. Wando County produced 8.2 billion sheets of dried gim in 2020 from 2,400 hectares.
Tidal flats along the Yellow Sea coast total 2,489 square kilometers, concentrated in Jeollanam-do and Chungcheongnam-do provinces. Suncheon Bay contains 28 square kilometers of mudflats bordering 5.4 square kilometers of reed beds, protected since 2006 as wetland reserve hosting 140,000 migratory waterbirds during spring and autumn passages. Elevated walkways extend 1.2 kilometers across reed beds to observation points overlooking mudflats. Getbol, the Korean term for tidal flats, achieved UNESCO World Heritage inscription in 2021 for four sites totaling 129 square kilometers at Seocheon, Gochang, Shinan, and Boseong-Suncheon.
Reclaimed land from tidal flat development totals 1,550 square kilometers, converting former mudflats to agricultural use through seawall construction. Saemangeum seawall, completed in 2010, extends 33.9 kilometers across Gimje Bay in Jeollabuk-do province, creating 409 square kilometers of reclaimed land intended for agriculture and development. Environmental opposition challenged the project from 1991 through construction, citing destruction of 400 square kilometers of tidal habitat supporting migratory bird populations. Subsequent reclamation projects face prohibition under 2008 legislation protecting remaining tidal flats.
Reservoir construction for irrigation created 17,500 farm ponds storing water for rice cultivation, though 70 percent date to the Joseon Dynasty period before 1910 and Japanese colonial period through 1945. The largest reservoirs include Junam Reservoir near Changwon, constructed in 1920, covering 2.5 square kilometers and hosting 70,000 wintering waterfowl. Upo Wetland in Changnyeong County contains 2.31 square kilometers of natural freshwater wetland connected to Nakdong River flooding, protected since 1999 as Ramsar wetland site. The site maintains traditional wetland fishing using bamboo traps called tong, harvested during spring drawdown.
Rivers remain central to rural landscapes despite flood control engineering that straightened channels and constructed embankments. The Han River drains 26,000 square kilometers, flowing 494 kilometers from Taebaek Mountains to the Yellow Sea at Incheon. The Nakdong River extends 510 kilometers from Taebaek to Korea Strait, draining 23,690 square kilometers through South Korea's southeastern provinces. Eight weirs constructed on the Nakdong between 2009 and 2011 under the Four Major Rivers Project maintain water levels for irrigation and recreation, though environmental groups advocate removal citing ecosystem disruption and algal blooms.
Terraced agriculture characterizes steep valley slopes throughout Gyeongsangbuk-do and Jeollanam-do provinces, where stone wall construction prevented erosion and created level planting surfaces. Namhae County contains approximately 1,800 hectares of stone-walled terraces, some documented to Goryeo Dynasty period 918-1392. Individual terrace plots measure 30 to 200 square meters, accessed by stone stairways. Garlic cultivation dominates terraced fields in Namhae, producing 12,000 tons annually marketed under geographical indication. Purple-flowering garlic fields create distinctive visual patterns during May flowering period visible across terraced hillsides.
Mountain roads access remote valleys where Buddhist temples established agricultural estates during Three Kingdoms period 57 BCE-668 CE. Haeinsa Temple in Gayasan National Park, housing Tripitaka Koreana woodblocks carved 1237-1249, maintains 120 hectares of temple farmland worked by monastics producing rice, vegetables, and doenjang fermented soybean paste using traditional methods. Temple landscapes preserve ancient tree specimens including zelkova, ginkgo, and Korean pine exceeding 500 years age. Stone walls enclosing temple precincts employ traditional dry-stack methods without mortar, maintaining techniques unchanged since Joseon Dynasty.
