Geography of Brazil
The country of
Braziloccupies roughly half of South America, bordering the Atlantic Ocean. Brazil covers a total area of 8,514,215 km² (3,287,357 sq mi) which includes 8,456,510 km² (3,265,076 sq mi) of land and 55,455 km² (21,411 sq mi) of water. The highest point in Brazil is Pico da Neblinaat 2,994 m (9,823 ft). Brazil is bordered by the countries of Argentina, Bolivia, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguayand Venezuela. By comparison, Brazil is slightly smaller in land mass than the United States.
Much of the
climateis tropical, with the south being relatively temperate. The largest river in Brazil, and one of the longest in the world, is the Amazon. The rainforestthat covers the Amazon Basinconstitutes almost half of the rainforests on Earth.
ize and location
With its expansive territory, Brazil occupies most of the eastern part of the South American continent and its geographic heartland, as well as various islands in the
Atlantic Ocean. The only countries in the world that are larger are Russia, Canada, the People's Republic of China, and the United States(including Alaska). The national territory extends convert|4395|km|mi|0|spell=us from north to south (5°16'20" N to 33°44'32" S latitude) and convert|4319|km|mi|0|spell=us from east to west (34°47'30" W to 73°59'32" W longitude). It spans three time zones, the westernmost of which is one hour ahead of Eastern Standard Time in the United States. The time zone of the capital (Brasília) and of the most populated part of Brazil along the east coast ( UTC-3) is two hours ahead of Eastern Standard Time, except when it is on its own daylight saving time, from October to February. The Atlantic islands are in the easternmost time zone.
Brazil possesses the archipelago of
Fernando de Noronha, located convert|350|km|mi|0|spell=us northeast of its "horn", and several small islands and atolls in the Atlantic - Abrolhos, Atol das Rocas, Penedos de São Pedro e São Paulo, Trindade, and Martim Vaz. In the early 1970s, Brazil claimed a territorial sea extending convert|362|km|mi|0|spell=us from the country's shores, including those of the islands.
On Brazil's east coast, the Atlantic coastline extends convert|7367|km|mi|0|spell=us. In the west, in clockwise order from the south, Brazil has convert|15719|km|mi|0|spell=us of borders with Uruguay,
Argentina, Paraguay, Bolivia, Peru, Colombia, Venezuela, Guyana, Suriname, and French Guiana. The only South American countries with which Brazil does not share borders are Chileand Ecuador. A few short sections are in question, but there are no major boundary controversies with any of the neighboring countries.
Geology, geomorphology, and drainage
In contrast to the
Andes, which rose to elevations of nearly convert|7000|m|ft|-2|spell=us in a relatively recent epoch and inverted the Amazon's direction of flow from westward to eastward, Brazil's geological formation is very old. Precambriancrystalline shields cover 36% of the territory, especially its central area. The principal mountain ranges average elevations just under convert|2000|m|ft|-2|spell=us. The Serra do MarRange hugs the Atlantic coast, and the Serra do EspinhaçoRange, the largest in area, extends through the south-central part of the country. The highest mountains are in the Tumucumaque, Pacaraima, and Imeri ranges, among others, which traverse the northern border with the Guianas and Venezuela.
In addition to mountain ranges (about 0.5% of the country is above 1,200 m), Brazil's Central Highlands include a vast central plateau (
Planalto Central). The plateau's uneven terrain has an average elevation of convert|1000|m|ft|-2|spell=us. The rest of the territory is made up primarily of sedimentary basins, the largest of which is drained by the Amazon and its tributaries. Of the total territory, 41% averages less than convert|200|m|ft|-1|spell=us in elevation. The coastal zone is noted for thousands of kilometers of tropical beaches interspersed with mangroves, lagoons, and dunes, as well as numerous coral reefs.
Brazil has one of the world's most extensive
river systems, with eight major drainage basins, all of which drain into the Atlantic Ocean. Two of these basins--the Amazon and Tocantins-Araguaia account for more than half the total drainage area. The largest river system in Brazil is the Amazon, which originates in the Andes and receives tributaries from a basin that covers 45.7% of the country, principally the north and west. The main Amazon river system is the Amazonas-Solimões-Ucayali axis (the convert|6762|km|mi|0|sing=on|spell=us-long Ucayali is a Peruvian tributary), flowing from west to east. Through the Amazon Basin flows one-fifth of the world's fresh water. A total of convert|3615|km|mi|0|spell=us of the Amazon are in Brazilian territory. Over this distance, the waters decline only about convert|100|m|ft|-1|spell=us. The major tributaries on the southern side are, from west to east, the Javari, Juruá, Purus (all three of which flow into the western section of the Amazon called the Solimões), Madeira, Tapajós, Xingu, and Tocantins. On the northern side, the largest tributaries are the Branco, Japurá, Jari, and Rio Negro. The above-mentioned tributaries carry more water than the Mississippi (its discharge is less than one-tenth that of the Amazon). The Amazon and some of its tributaries, called "white" rivers, bear rich sediments and hydrobiological elements. The black-white and clear rivers--such as the Negro, Tapajós, and Xingu--have clear (greenish) or dark water with few nutrients and little sediment.
The major river system in the Northeast is the Rio São Francisco, which flows convert|1609|km|mi|0|spell=us northeast from the south-central region. Its basin covers 7.6% of the national territory. Only convert|277|km|mi|0|spell=us of the lower river are navigable for oceangoing ships. The Paraná system covers 14.5% of the country. The Paraná flows south among the
Río de la Plata Basin, reaching the Atlantic between Argentina and Uruguay. The headwaters of the Paraguai, the Paraná's major eastern tributary, constitute the Pantanal, the largest contiguous wetlands in the world, covering as much as convert|230000|km2|sqmi|-3|spell=us.
Below their descent from the highlands, many of the tributaries of the Amazon are navigable. Upstream, they generally have
rapids or waterfalls, and boats and barges also must face sandbars, trees, and other obstacles. Nevertheless, the Amazon is navigable by oceangoing vessels as far as convert|3885|km|mi|0|spell=us upstream, reaching Iquitosin Peru. The Amazon river system was the principal means of access until new roads became more important in the 1970s. The São Francisco was also used for transportation in the past. Dams and locks in the Paraná system have made it an important artery for interstate and international trade in the 1990s.
The various river systems descending from the shields have endowed Brazil with vast
hydroelectricpotential, estimated at 129,046 megawatts (MW), of which 30,065 MW were in operation or under construction in 1991. The largest hydroelectric projects are Itaipu, in Paraná, with 12,600 MW; Tucuruí, in Pará, with 7,746 MW; and Paulo Afonso, in Bahia, with 3,986 MW.
Natural resourcesinclude: bauxite, gold, iron ore, manganese, nickel, phosphates, platinum, tin, uranium, petroleum, hydropowerand timber.
Rivers and lakes
Amazon Riveris the widest and second longest river (behind the Nile) in the world. This huge river waters the majority of the world's rainforests. Another rather large river called the Paraná, has its source in Brazil. It forms the border of Paraguay and Argentina, then winds its way through Argentina and into the Atlantic Ocean, along Uruguay. The HBV hydrology transport modelhas been used to analyze certain pollutant transport in Brazil's river systems.The Amazon is full of eroding soil.
Soils and vegetation
Brazil's tropical soils produce 70 million tons of grain crops per year, but this output is attributed more to their extension than their fertility. Despite the earliest Portuguese explorers' reports that the land was exceptionally fertile and that anything planted grew well, the record in terms of sustained agricultural productivity has been generally disappointing. High initial fertility after clearing and burning usually is depleted rapidly, and acidity and aluminum content are often high. Together with the rapid growth of
weeds and pests in cultivated areas, as a result of high temperatures and humidity, this loss of fertility explains the westward movement of the agricultural frontier and slash-and-burn agriculture; it takes less investment in work or money to clear new land than to continue cultivating the same land. Burning also is used traditionally to remove tall, dry, and nutrient-poor grass from pasture at the end of the dry season. Until mechanization and the use of chemical and genetic inputs increased during the agricultural intensification period of the 1970s and 1980s, coffeeplanting and farming in general moved constantly onward to new lands in the west and north. This pattern of horizontal or extensive expansion maintained low levels of technology and productivity and placed emphasis on quantity rather than quality of agricultural production.
The largest areas of fertile soils, called terra roxa (red earth), are found in the states of Paraná and
São Paulo. The least fertile areas are in the Amazon, where the dense rain forestis. Soils in the Northeast are often fertile, but they lack water, unless they are irrigated artificially.
In the 1980s, investments made possible the use of irrigation, especially in the Northeast Region and in
Rio Grande do SulState, which had shifted from grazing to soyand riceproduction in the 1970s. Savannasoils also were made usable for soybean farming through acidity correction, fertilization, plant breeding, and in some cases spray irrigation. As agriculture underwent modernization in the 1970s and 1980s, soil fertility became less important for agricultural production than factors related to capital investment, such as infrastructure, mechanization, use of chemical inputs, breeding, and proximity to markets. Consequently, the vigor of frontier expansion weakened.
The variety of climates, soils, and drainage conditions in Brazil is reflected in the range of its vegetation types. The Amazon Basin and the areas of heavy rainfall along the Atlantic coast have tropical rain forest composed of
broadleafevergreen trees. The rain forest may contain as many as 3,000 speciesof floraand faunawithin a convert|2.6|km2|sqmi|0|spell=us|sing=on area. The Atlantic Forest is reputed to have even greater biological diversity than the Amazon rain forest, which, despite apparent homogeneity, contains many types of vegetation, from high canopy forest to bamboo groves.
In the semiarid Northeast,
Caatinga, a dry, thick, thorny vegetation, predominates. Most of central Brazil is covered with a woodland savanna, known as the Cerrado(sparse scrub trees and drought-resistant grasses), which became an area of agricultural development after the mid-1970s. In the South (Sul), needle-leaved pinewoods (Paraná pine or araucaria) cover the highlands; grassland similar to the Argentine pampacovers the sea-level plains. The Mato Grosso swamplands ( PantanalMato-grossense) is a Florida-sized plain in the western portion of the Center-West (Centro-Oeste). It is covered with tall grasses, bushes, and widely dispersed trees similar to those of the cerrado and is partly submerged during the rainy season.
Brazil, which is named after reddish dyewood (
pau brasil), has long been famous for the wealth of its tropical forests. These are not, however, as important to world markets as those of Asia and Africa, which started to reach depletion only in the 1980s. By 1996 more than 90% of the original Atlantic forest had been cleared, primarily for agriculture, with little use made of the wood, except for araucaria pine in Paraná.
The inverse situation existed with regard to clearing for wood in the Amazon rain forest, of which about 15% had been cleared by 1994, and part of the remainder had been disturbed by selective logging. Because the Amazon forest is highly heterogeneous, with hundreds of woody species per
hectare, there is considerable distance between individual trees of economic value, such as mahoganyand cerejeira. Therefore, this type of forest is not normally cleared for timber extraction but logged through high-grading, or selection of the most valuable trees. Because of vines, felling, and transportation, their removal causes destruction of many other trees, and the litter and new growth create a risk of forest fires, which are otherwise rare in rain forests. In favorable locations, such as Paragominas, in the northeastern part of ParáState, a new pattern of timber extraction has emerged: diversification and the production of plywoodhave led to the economic use of more than 100 tree species.
Starting in the late 1980s, rapid deforestation and extensive burning in Brazil received considerable international and national attention.
Satellite images have helped document and quantify deforestation as well as fires, but their use also has generated considerable controversy because of problems of defining original vegetation, cloud cover, and dealing with secondary growth and because fires, as mentioned above, may occur in old pasture rather than signifying new clearing. Public policies intended to promote sustainable management of timber extraction, as well as sustainable use of nontimber forest products (such as rubber, Brazil nuts, fruits, seeds, oils, and vines), were being discussed intensely in the mid-1990s. However, implementing the principles of sustainable development, without irreversible damage to the environment, proved to be more challenging than establishing international agreements about them.
Although 90% of the country is within the
tropical zone, the climate of Brazil varies considerably from the mostly tropical North (the equatortraverses the mouth of the Amazon) to temperate zones below the Tropic of Capricorn(23°27' S latitude), which crosses the country at the latitude of the city of São Paulo. Brazil has five climatic regions: equatorial, tropical, semiarid, highland tropical, and subtropical.
Temperatures along the equator are high, averaging above convert|25|C|F|0, but not reaching the summer extremes of up to convert|40|C|F|0 in the temperate zones. There is little seasonal variation near the equator, although at times it can get cool enough for wearing a jacket, especially in the rain. At the country's other extreme, there are frosts south of the Tropic of Capricorn during the winter (June-August), and in some years there is snow in the mountainous areas, such as
Rio Grande do Suland Santa Catarina. Temperatures in the cities of São Paulo, Belo Horizonte, and Brasíliaare moderate (usually between convert|15|C|F|0|disp=/ and convert|30|C|F|0|disp=/), despite their relatively low latitude, because of their elevation of approximately convert|1000|m|ft|-2|spell=us. Rio de Janeiro, Recife, and Salvador on the coast have warm climates, with average temperatures ranging from convert|23|C|F|0 to convert|27|C|F|0, but enjoy constant trade winds. The southern cities of Porto Alegreand Curitibahave a subtropical climate similar to that in parts of the United States and Europe, and temperatures can fall below freezing in winter.
Precipitation levels vary widely. Most of Brazil has moderate
rainfallof between 1,000 and 1,500 millimeters (40–60 in) a year, with most of the rain falling in the summer (between December and April) south of the Equator. The Amazon regionis notoriously humid, with rainfall generally more than convert|2000|mm|in|-1 per year and reaching as high as convert|3000|mm|in|-1 in parts of the western Amazon and near Belém. It is less widely known that, despite high annual precipitation, the Amazon rain forest has a three- to five-month dry season, the timing of which varies according to location north or south of the equator.
High and relatively regular levels of precipitation in the Amazon contrast sharply with the dryness of the semiarid Northeast, where rainfall is scarce and there are severe droughts in cycles averaging seven years. The Northeast is the driest part of the country. The region also constitutes the hottest part of Brazil, where during the dry season between May and November, temperatures of more than convert|38|C|F|0 have been recorded. However, the
sertão, a region of semidesert vegetation used primarily for low-density ranching, turns green when there is rain. Most of the Center-West has 1,500 to 2,000 millimeters (60–79 in) of rain per year, with a pronounced dry season in the middle of the year, while the South and most of the year without a distinct dry season.
Brazil's twenty-six states and the Federal District (Distrito Federal) are divided conventionally into five regions: North (Norte), Northeast (Nordeste), Southeast (Sudeste), South (Sul), and Center-West (Centro-Oeste) - see fig. 4. In 1996 there were 5,581
municipalities (municípios), which have municipal governments. Many municipalities, which are comparable to United States counties, are in turn divided into districts (distritos), which do not have politicalor administrative autonomy. In 1995 there were 9,274 districts. All municipal and district seats, regardless of size, are considered officially to be urban. For purely statistical purposes, the municipalities were grouped in 1990 into 559 micro-regions, which in turn constituted 136 meso-regions. This grouping modified the previous micro-regional division established in 1968, a division that was used to present census data for 1970, 1975, 1980, and 1985.
Each of the five major regions has a distinct
ecosystem. Administrative boundaries do not necessarily coincide with ecological boundaries, however. In addition to differences in physical environment, patterns of economic activityand population settlement vary widely among the regions. The principal ecological characteristics of each of the five major regions, as well as their principal socioeconomic and demographic features, are summarized below.
The Center-West consists of the states of Goiás,
Mato Grosso, and Mato Grosso do Sul(separated from Mato Grosso in 1979), as well as the Federal District, site of Brasília, the national capital. Until 1988 Goiás State included the area that then became the state of Tocantins in the North.
The Center-West has convert|1612077|km2|sqmi|0|spell=us and covers 18.9% of the national territory. Its main biome is the
cerrado, the tropical savanna in which natural grassland is partly covered with twisted shrubs and small trees. The cerrado was used for low-density cattle-raising in the past but is now also used for soybean production. There are gallery forests along the rivers and streams and some larger areas of forest, most of which have been cleared for farmingand livestock. In the north, the cerrado blends into tropical forest. It also includes the Pantanal wetlands in the west, known for their wildlife, especially aquatic birds and caymans. In the early 1980s, 33.6% of the region had been altered by anthropic activities, with a low of 9.3% in Mato Grosso and a high of 72.9% in Goiás (not including Tocantins). In 1996 the Center-West region had 10.2 million inhabitants, or 6% of Brazil's total population. The average density is low, with concentrations in and around the cities of Brasília, Goiânia, Campo Grande, and Cuiabá. Living standards are below the national average. In 1994 they were highest in the Federal District, with per capita income of US$7,089 (the highest in the nation), and lowest in Mato Grosso, with US$2,268.
The nine states that make up the Northeast are
Alagoas, Bahia, Ceará, Maranhão, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, and Sergipe. The former federal territory of Fernando de Noronhawas incorporated into Pernambuco State in 1988. For planning or ecological purposes, Maranhão west of 44° W longitude, most of which until recently was covered with "pre-Amazon" forest (that is, transition from the cerrado or caatinga to tropical forest), is often included in the Amazon region.
The Northeast, with convert|1561178|km2|sqmi|0|spell=us, covers 18.3% of the national territory. Its principal biome is the semiarid
caatingaregion, which is subject to prolonged periodic droughts. By the 1990s, this region utilized extensive irrigation. In an area known as the forest zone ( zona da mata), the Atlantic Forest, now almost entirely gone, once stretched along the coastline as far north as Rio Grande do Norte. Sugar plantations established there in colonial times persisted for centuries. Between the mata and the sertão lies a transition zone called the agreste, an area of mixed farming. In 1988-89, 46.3% of the region had been subjected to anthropic activity, ranging from a low of 10.8% in Maranhão to a high of 77.2% in Alagoas.
Because its high rates of natural increase offset heavy out-migration, the Northeast's large share of the country's total population declined only slightly during the twentieth century. In 1996 the region had 45 million inhabitants, 28% of Brazil's total population. The population is densest along the coast, where eight of the nine state capitals are located, but is also spread throughout the interior. The major cities are Salvador, in Bahia;
Recife, in Pernambuco; and Fortaleza, in Ceará. The region has the country's largest concentration of rural population, and its living standards are the lowest in Brazil. In 1994 Piauí had the lowest per capita income in the region and the country, only US$835, while Sergipe had the highest average income in the region, with US$1,958.
The equatorial North, also known as the Amazon or
Amazônia, includes, from west to east, the states of Rondônia, Acre, Amazonas, Roraima, Pará, Amapá, and, as of 1988, Tocantins (created from the northern part of Goiás State, which is situated in the Center-West). Rondônia, previously a federal territory, became a state in 1986. The former federal territories of Roraima and Amapá were raised to statehood in 1988.
With convert|3869638|km2|sqmi|0|spell=us, the North is the country's largest region, covering 45.3% of the national territory. The region's principal
biomeis the humid tropical forest, also known as the rain forest, home to some of the planet's richest biological diversity. The North has served as a source of forest products ranging from "backlands drugs" (such as sarsaparilla, cocoa, cinnamon, and turtle butter) in the colonial period to rubber and Brazil nuts in more recent times. In the mid-twentieth century, nonforest products from mining, farming, and livestock-raising became more important, and in the 1980s the lumber industryboomed. In 1990, 6.6% of the region's territory was considered altered by anthropic (man-made) action, with state levels varying from 0.9% in Amapá to 14.0% in Rondônia.
In 1996 the North had 11.1 million inhabitants, only 7% of the national total. However, its share of Brazil's total had grown rapidly in the 1970s and early 1980s as a result of interregional migration, as well as high rates of natural increase. The largest population concentrations are in eastern Pará State and in Rondônia. The major cities are
Belémand Santarémin Pará, and Manausin Amazonas. Living standards are below the national average. The highest per capita income, US$2,888, in the region in 1994, was in Amazonas, while the lowest, US$901, was in Tocantins.
The Southeast consists of the four states of
Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo. Its total area of convert|927286|km2|sqmi|0|spell=us corresponds to 10.9% of the national territory. The region has the largest share of the country's population, 63 million in 1991, or 39% of the national total, primarily as a result of internal migration since the mid-nineteenth century until the 1980s. In addition to a dense urban network, it contains the megacities of São Paulo and Rio de Janeiro, which in 1991 had 18.7 million and 11.7 million inhabitants in their metropolitan areas, respectively. The region combines the highest living standards in Brazil with pockets of urban poverty. In 1994 São Paulo boasted an average income of US$4,666, while Minas Gerais reported only US$2,833.
Originally, the principal biome in the Southeast was the Atlantic Forest, but by 1990 less than 10% of the original forest cover remained as a result of clearing for farming, ranching, and charcoal making. Anthropic activity had altered 79.5% of the region, ranging from 75% in Minas Gerais to 91.1% in Espírito Santo. The region has most of Brazil's industrial production. The state of São Paulo alone accounts for half of the country's industries. Agriculture, also very strong, has diversified and now uses modern technology.
The three states in the temperate South: Paraná, Rio Grande do Sul, and Santa Catarina--cover convert|577214|km2|sqmi|0|spell=us, or 6.8% of the national territory. The population of the South in 1991 was 23.1 million, or 14% of the country's total. The region is almost as densely settled as the Southeast, but the population is more concentrated along the coast. The major cities are
Curitibaand Porto Alegre. The inhabitants of the South enjoy relatively high living standards. Because of its industry and agriculture, Paraná had the highest average income in 1994, US$3,674, while Santa Catarina, a land of small farmers and small industries, had slightly less, US$3,405.
In addition to the
Atlantic Forestand Araucaria moist forests, much of which were cleared in the post-World War II period, the southernmost portion of Brazil contains the Uruguayan savanna, which extends into Argentinaand Uruguay. In 1982, 83.5% of the region had been altered by anthropic activity, with the highest level (89.7%) in Rio Grande do Sul, and the lowest (66.7%) in Santa Catarina. Agriculture--much of which, such as riceproduction, is carried out by small farmers--has high levels of productivity. There are also some important industries.
The environmental problem that attracted most international attention in Brazil in the 1980s was undoubtedly deforestation in the Amazon. Of all
Latin American countries, Brazil still has the largest portion (66%) of its territory covered by forests, but clearingand burningin the Amazon proceeded at alarming rates in the 1970s and 1980s. Most of the clearing resulted from the activities of ranchers, including large corporate operations, and a smaller portion resulted from slash and burntechniques used by small farmers.
Deforestation in the Amazon declined from levels averaging convert|22000|km2|sqmi|-2|spell=us per year during the 1970-88 period to about convert|11000|km2|sqmi|-2|spell=us per year between 1988 and 1991. There was controversy about the levels in the mid-1990s. Knowledgeable experts placed the level of accumulated deforestation at about 15% in 1996, as opposed to 12% in 1991. Although unseasonal
rainfallpatterns may explain some year-to-year variation, the basic cause for the decline in deforestation after 1987 was economic crisis. There was insufficient capital, credit, or incentive for large-scale clearing, as well as insufficient public investment to stimulate new migration. Migration to the Amazon also fell quickly in the late 1980s. More effective enforcement of government regulations and bad publicity for large offenders, both of which were associated with changes in public opinion about the environment, also played a part. Technical changes involved in the transition from horizontal expansion of agriculture to increasing productivity also accounted for decreasing rates of deforestation. Desertification, another important environmental problem in Brazil, only received international attention following the United NationsConference on the Environment and Development, also known as the Earth Summit, held in Rio de Janeiro in June 1992. Desertification means that the soils and vegetation of drylands are severely degraded, not necessarily that land turns into desert. In the early 1990s, it became evident that the semiarid caatingaecosystem of the Northeast was losing its natural vegetation through clearing and that the zone was therefore running the risk of becoming even more arid, as was occurring also in some other regions.
In areas where
agricultureis more intense and developed, there are serious problems of soil erosion, siltation and sedimentationof streams and rivers, and pollution with pesticides. In parts of the savannas, where irrigated soybeanproduction expanded in the 1980s, the water tablehas been affected. Expansion of pastures for cattleraising has reduced natural biodiversityin the savannas. Swine effluents constitute a serious environmental problem in Santa Catarina in the South.
urban areas, at least in the largest cities, levels of air pollutionand congestionare typical of, or worse than, those found in cities in developed countries. At the same time, however, basic environmental problems related to the lack of sanitation, which developed countries solved long ago, persist in Brazil. These problems are sometimes worse in middle-sized and small cities than in large cities, which have more resources to deal with them. Environmental problems of cities and towns finally began to receive greater attention by society and the government in the 1990s.
According to many critics, the
economic crisisin the 1980s worsened environmental degradation in Brazil because it led to overexploitation of natural resources, stimulated settlement in fragile lands in both rural and urban areas, and weakened environmental protection. At the same time, however, the lower level of economic activity may have reduced pressure on the environment, such as the aforementioned decreased level of investment in large-scale clearing in the Amazon. That pressure could increase if economic growth accelerates, especially if consumption patterns remain unchanged and more sustainable forms of production are not found.
In Brazil public policies regarding the environment are generally advanced, although their implementation and the enforcement of
environmental laws have been far from ideal. Laws regarding forests, water, and wildlifehave been in effect since the 1930s. Brazil achieved significant institutional advances in environmental policy design and implementation after the Stockholm Conference on the Environmentin 1972. Specialized environmental agencies were organized at the federal level and in some states, and many national parks and reserves were established. By 1992 Brazil had established thirty-four national parks and fifty-six biological reserves. In 1981 the National Environment Policy was defined, and the National System for the Environment (Sistema Nacional do Meio Ambiente-- Sisnama) was created, with the National Environmental Council (Conselho Nacional do Meio Ambiente-- Conama) at its apex, municipal councils at its base, and state-level councils in between. In addition to government authorities, all of these councils include representatives of civil society.
1988 constitutionincorporates environmental precepts that are advanced compared with those of most other countries. At that time, the Chamber of Deputies(Câmara dos Deputados) established its permanent Commission for Defense of the Consumer, the Environment, and Minorities. In 1989 the creation of the Brazilian Institute for the Environment and Renewable Natural Resources (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis-- Ibama) joined together the federal environment secretariat and the federal agencies specializing in forestry, rubber, and fisheries. In 1990 the administration of Fernando Collor de Mello(president, 1990-92) appointed the well-known environmentalist José Lutzembergeras secretary of the environment and took firm positions on the environment and on Indian lands. In 1992 Brazil played a key role at the Earth Summit, not only as its host but also as negotiator on sustainable development agreements, including the conventions on climate and biodiversity. The Ministry of Environment was created in late 1992, after President Collor had left office. In August 1993, it became the Ministry of Environment and the Legal Amazonand took a more pragmatic approach than had the combative Lutzemberger. However, because of turnover in its leadership, a poorly defined mandate, and lack of funds, its role and impact were limited. In 1995 its mandate and name were expanded to include water resources--the Ministry of Environment, Hydraulic Resources, and the Legal Amazon--it began a process of restructuring to meet its mandate of "shared management of the sustainable use of natural resources." In 1997 the Commission on Policies for Sustainable Development and Agenda 21 began to function under the aegis of the Civil Household. One of its main tasks was to prepare Agenda 21 (a plan for the twenty-first century) for Brazil and to stimulate preparation of state and local agendas.
Institutional development at the official level was accompanied and in part stimulated by the growth, wide diffusion, and growing professional development of
nongovernmental organizations ( NGOs) dedicated to environmental and socio-environmental causes. The hundreds of NGOs throughout Brazil produce documents containing both useful information and passionate criticisms. Among the Brazilian environmental NGOs, the most visible are SOS Atlantic Forest ( SOS Mata Atlântica), the Social-Environmental Institute (Instituto Sócio-Ambiental--ISA), the Pro-Nature Foundation (Fundação Pró-Natureza--Funatura), and the Amazon Working Group (Grupo de Trabalho Amazônico--GTA). The Brazilian Forum of NGOs and Social Movements for the Environment and Development and the Brazilian Association of Nongovernmental Organizations (Associacão Brasileira de Organizações Não-Governamentais--ABONG) are national networks, and there are various regional and thematic networks as well. The main international environmental NGOs that have offices or affiliates in Brazil are the World Wildlife Fund (WWF), Conservation International (CI), and Nature Conservancy.
Especially after the events of the late 1980s, international organizations and developed countries have allocated significant resources for the environmental sector in Brazil. In 1992 environmental projects worth about US$6.8 million were identified, with US$2.6 in counterpart funds (funds provided by the Brazilian government). More than 70% of the total value was for sanitation, urban pollution control, and other urban environmental projects. Thus, the allocation of resources did not accord with the common belief that funding was influenced unduly by alarmist views on deforestation in the Amazon.
Among the specific environmental projects with international support, the most important was the National Environmental Plan (Plano Nacional do Meio Ambiente--PNMA), which received a US$117 million loan from the World Bank. The National Environmental Fund (Fundo Nacional do Meio Ambiente--FNMA), in addition to budgetary funds, received US$20 million from the Inter-American Development Bank to finance the environmental activities of NGOs and small municipal governments. The Pilot Program for the Conservation of the Brazilian Rain Forests (Programa Piloto para a Proteção das Florestas Tropicais do Brasil--PPG-7) was supported by the world's seven richest countries (the so-called G-7) and the European Community, which allocated US$258 million for projects in the Amazon and Atlantic Forest regions. The Global Environment Facility (GEF), created in 1990, set aside US$30 million for Brazil, part of which is managed by a national fund called Funbio. GEF also established a small grants program for NGOs, which focused on the cerrado during its pilot phase. The World Bank also made loans for environmental and natural resource management in Rondônia and Mato Grosso, in part to correct environmental and social problems that had been created by the World Bank-funded development of the northwest corridor in the 1980s.
Despite favorable laws, promising institutional arrangements, and external funding, the government has not, on the whole, been effective in controlling damage to the environment. This failure is only in small measure because of the opposition of anti-environmental groups. In greater part, it can be attributed to the traditional separation between official rhetoric and actual practice in Brazil. It is also related to general problems of governance, fiscal crisis, and lingering doubts about appropriate tradeoffs between the environment and development. Some of the most effective governmental action in the environmental area has occurred at the state and local levels in the most developed states and has involved NGOs. In 1994 the PNMA began to stress decentralization and strengthening of state environmental agencies, a tendency that subsequently gained momentum.
Environment - current issues:
deforestationin Amazon Basin destroys the habitat and endangers the existence of a multitude of plant and animal species indigenous to the area; air and water pollution in Rio de Janeiro, São Paulo, and several other large cities; land degradation and water pollution caused by improper mining activities
"note:"President Cardoso in September 1999 signed into force an environmental crime bill which for the first time defines
pollutionand deforestation as crimes punishable by stiff fines and jail sentences
