Piura is a coastal region in northwestern Peru. The region's capital is Piura and its largest port cities, Paita and Talara, are also among the most important in Peru. The area is known for its warm tropical and dry or semi-tropical beaches. The country's latest decentralization program is in hiatus after the proposal to merge departments was defeated in the national referendum in October 2005.〔(US State department at www.state.gov July 2007 "Background Note: Peru" )〕 The referendum held on October 30, 2005, as part of the ongoing decentralization process in Peru, to decide whether the region would merge with the current regions of Lambayeque and Tumbes to create a new ''Región Norte'' was defeated. ==Geography== The Piura Region is bordered to the north by the Tumbes Region and Ecuador, to the east by Cajamarca Region, to the south by the Lambayeque Region, and to the west by the Pacific Ocean. "Punta Pariñas" in Piura is South America's most western point. The territory of the Piura Region has many climate variations due to its geographical location. It is just 4 degrees south of the equator, yet receives two ocean currents at the same time: the cold Humboldt Current (13-20 °C 55-68 F) and the warm El Niño Current (20-27 °C, 68-80 F). This makes the Piura Region a land that is both tropical and arid at the same time, ''The Land where the Tropics meets The Desert'' The coast is divided by the Peruvian ''subtropical desert'' of Sechura on the south and savanna-like scrub tropical dry forests to the center and north of the region. There are also small valleys of tropical climate, where rice and coconut fields are common, especially around the Piura and Sullana rivers. There is a high Amazon climate (''selva alta'') as one goes away from the coast onto the sierra; Páramo climates and cooler temperatures appear as one climbs the sierra. Topography is smooth in the coast and rough in the Sierra. There are many arid plains in the southern region. The Sechura Desert, located south of the Piura River, is Peru's largest desert and one of the world's few examples of a tropical desert; it borders a tropical terrain to the north. The Bayóvar Depression, which is the lowest point in Peru and all of the Southern Tropics, is located in this desert. The morphological forms most common in the coast are the dry ravine that suddenly become copious when there are heavy rains, forming tropical dry forests all over. Other features are half-moon shaped dunes, the marine terraces such as those of Máncora, Talara and Lobitos. Valleys have been formed by fluvial terraces of the Chira River and Piura River. To the east, valleys are more or less deep and have been eroded by rivers forming ''equatorial tropical-dry-forests''. The major peak surpasses 3000 m. The Paso de Porculla, in the southwest of the territory is only 2,138 meters high and is the lowest pass of the Peruvian Andes. The rivers crossing its territory belong both to the Pacific watershed and to the Amazon Basin. The Chira River is the most important and flows into the Pacific Ocean. The Piura River also flows into the Pacific Ocean although the flow varies greatly with the changing seasons and during severe droughts will dry up. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Piura Region」の詳細全文を読む スポンサード リンク
