PerúRepublic of PeruPeruvian
Peru (Perú ; Piruw Republika ; Piruw Suyu ), officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peru is a megadiverse country with habitats ranging from the arid plains of the Pacific coastal region in the west to the peaks of the Andes mountains vertically extending from the north to the southeast of the country to the tropical Amazon Basin rainforest in the east with the Amazon river.

Cotton

cotton woolcotton industrycotton fiber
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds.

Aqueduct (water supply)

aqueductaqueductsconduit
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term aqueduct also often refers specifically to a bridge on an artificial watercourse. The word is derived from the Latin aqua ('water') and ducere ('to lead'). Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. In modern times, the largest aqueducts of all have been built in the United States to supply the country's biggest cities. The simplest aqueducts are small ditches cut into the earth.

Nazca

NascaRio Grande de Nazcacultures
Nazca (sometimes spelled Nasca) is a city and system of valleys on the southern coast of Peru. It is also the name of the largest existing town in the Nazca Province. The name is derived from the Nazca culture that flourished in the area between 100 BC and 800 AD. This culture was responsible for the Nazca Lines and the ceremonial city of Cahuachi; they also constructed an impressive system of underground aqueducts, named Puquios, that still function today.

Puquios

Pukyus
The puquios are an old system of subterranean aqueducts near the city of Nazca, Peru. Out of 36 puquios, most are still functioning and even relied upon to bring fresh water into the arid desert. The puquios have never been fully mapped, nor have any been excavated.

Potato

The potato is a root vegetable native to the Americas, a starchy tuber of the plant Solanum tuberosum, and the plant itself, a perennial in the family Solanaceae.

Nazca culture

NazcaNascaIca-Nazca culture
Some of the best-preserved channels are those located in Cantalloc. The Nazca culture is characterized by its beautiful polychrome pottery, painted with at least 15 distinct colors. The shift from post-fire resin painting to pre-fire slip painting marked the end of Paracas-style pottery and the beginning of Nazca-style pottery. The use of pre-fire slip painting meant that a great deal of experimentation took place in order to know which slips produced certain colors. Major pottery shapes include double-spout bottles, bowls, cups, vases, effigy forms, and mythical creatures.

Moche culture

MocheMochicaMoche civilization
The Moche civilization (alternatively, the Mochica culture or the Early, Pre- or Proto-Chimú) flourished in northern Peru with its capital near present-day Moche, Trujillo, Peru from about 100 to 700 AD during the Regional Development Epoch. While this issue is the subject of some debate, many scholars contend that the Moche were not politically organized as a monolithic empire or state. Rather, they were likely a group of autonomous polities that shared a common culture, as seen in the rich iconography and monumental architecture that survives today.

El Niño

El NinoEl Nino-Southern OscillationEl Niño Southern Oscillation
El Niño is the warm phase of the El Niño–Southern Oscillation (ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific (between approximately the International Date Line and 120°W), including the area off the Pacific coast of South America. The ENSO is the cycle of warm and cold sea surface temperature (SST) of the tropical central and eastern Pacific Ocean. El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific. El Niño phases are known to occur close to four years, however, records demonstrate that the cycles have lasted between two and seven years.

Drought

droughtsdrought reliefdry
A drought or drouth is an event of prolonged shortages in the water supply, whether atmospheric (below-average precipitation), surface water or ground water. A drought can last for months or years, or may be declared after as few as 15 days. It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy. Annual dry seasons in the tropics significantly increase the chances of a drought developing and subsequent bush fires. Periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour.

Cucurbita

squashsquashesmarrow
Cucurbita (Latin for gourd) is a genus of herbaceous vines in the gourd family, Cucurbitaceae, also known as cucurbits, native to the Andes and Mesoamerica. Five species are grown worldwide for their edible fruit, variously known as squash, pumpkin, or gourd depending on species, variety, and local parlance, and for their seeds. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus Lagenaria, which is in the same family and subfamily as Cucurbita but in a different tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of Cucurbita species.

Peanut

groundnutArachis hypogaeagroundnuts
The peanut, also known as the groundnut, goober (US), or monkey nut (UK), and taxonomically classified as Arachis hypogaea, is a legume crop grown mainly for its edible seeds. It is widely grown in the tropics and subtropics, being important to both small and large commercial producers. It is classified as both a grain legume and, due to its high oil content, an oil crop. World annual production of shelled peanuts was 44 million tonnes in 2016, led by China with 38% of the world total. Atypically among legume crop plants, peanut pods develop underground (geocarpy) rather than above ground.

Humboldt Current

HumboldtPeruHumboldt ocean current
The Humboldt Current, also called the Peru Current, is a cold, low-salinity ocean current that flows north along the western coast of South America. It is an eastern boundary current flowing in the direction of the equator, and extends 500-1000 km offshore. The Humboldt Current is named after the Prussian naturalist Alexander von Humboldt. In 1846, von Humboldt reported measurements of the cold-water current in his book Cosmos.

Overfishing

overfishedover-fishingfishing pressure
Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish in time, resulting in those species either becoming depleted or very underpopulated in that given area. Overfishing has spread all over the globe and has been present for centuries.

Andes

AndeanAndes MountainsAndean region
The Andes or Andean Mountains (Cordillera de los Andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The Andes also have the 2nd most elevated highest peak of any mountain range, only behind the Himalayas. The range is 7000 km long, 200 to 700 km wide (widest between 18° south and 20° south latitude), and has an average height of about 4000 m. The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.

Natural resource

natural resourcesresourcesmineral resources
Natural resources are resources that exist without actions of humankind. This includes all valued characteristics such as magnetic, gravitational, electrical properties and forces, etc. On Earth it includes sunlight, atmosphere, water, land (includes all minerals) along with all vegetation, crops and animal life that naturally subsists upon or within the heretofore identified characteristics and substances.

Tin

SnGray tintinfoil
Tin is a chemical element with the symbol Sn (from stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent, the so-called tin cry can be heard as a result of sliding tin crystals reforming; this trait is shared by indium, cadmium, and frozen mercury. Pure tin after solidifying keeps a mirror-like appearance similar to most metals. However, in most tin alloys (such as pewter), the metal solidifies with a dull gray color. Tin is a post-transition metal in group 14 of the periodic table of elements.

Silver

Agsilver orenative silver
Silver is a chemical element with the symbol Ag (from the Latin argentum, derived from the Proto-Indo-European h₂erǵ: "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Gold

Aunative goldgold dust
Gold is a chemical element with the symbol Au (from aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium.

Guano

bat guanowanudroppings
Guano (via Spanish from wanu) is the accumulated excrement of seabirds and bats. As a manure, guano is a highly effective fertilizer due to its exceptionally high content of nitrogen, phosphate and potassium: key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials.

Natural rubber

Brazil (Brasil; ), officially the Federative Republic of Brazil (República Federativa do Brasil, ), is the largest country in both South America and Latin America. At 8.5 million square kilometers (3.2 million square miles) and with over 208 million people, Brazil is the world's fifth-largest country by area and the fifth most populous. Its capital is Brasília, and its most populated city is São Paulo. The federation is composed of the union of the 26 states, the Federal District, and the 5,570 municipalities.

Inca road system

Qhapaq Ñanroad systemCamino Real
The Inca road system (often spelled Inka road system and known as Qhapaq Ñan meaning "royal road" in Quechua ) was the most extensive and advanced transportation system in pre-Columbian South America. It was at least 40,000 km long. The construction of the roads required a large expenditure of time and effort.
