903-559: A different venue. Columbus's second voyage in 1493 had a large contingent of settlers and goods to accomplish that. On Hispaniola, the city of Santo Domingo was founded in 1496 by Christopher Columbus's brother Bartholomew Columbus and became a stone-built, permanent city. Non-Castilians, such as Catalans and Aragonese , were often prohibited from migrating to the New World. Following the settlement of Hispaniola, Europeans began searching elsewhere to begin new settlements, since there

1032-598: A force led by Pánfilo de Narváez to punish the insubordinate Cortés for his unauthorized invasion of Mexico, but they were defeated at the Battle of Cempoala on 29 May 1520. Narváez was wounded and captured and 17 of his troops were killed; the rest joined Cortés. Meanwhile, Pedro de Alvarado triggered an Aztec uprising following the massacre in the Great Temple of Tenochtitlan , during which 400 Aztec nobles and 2,000 onlookers were killed. The Castilians were driven out of

1548-455: A major impact on the coast's rural development. In 2001, rural poverty in the region was 5.2%. Poverty has fallen only slowly in the Andean region, where poverty reaches 70 percent of the population. Many Andean Indigenous remain trapped in subsistence farming on small plots and rudimentary irrigation systems. The region produces only one-third of the country's agricultural GDP. Irrigation plays

1677-435: A number of legal and commercial issues that will affect how these projects move forward and are structured. Whilst some of the legal issues are not confined to irrigation PPPs they can take on a new dimension and complexity when applied to irrigation: Land ownership; water extraction; public sector counterpart. These will be key issues in a PPP as the private provider will want to ensure a steady revenue stream. There are also

1806-767: A number of revolts across the Spanish Habsburg's domains, including their Spanish kingdoms. During the Habsburg rule, the Spanish Empire significantly expanded its territories in the Americas, beginning with the conquest of the Aztec Empire ; these conquests were achieved not by the Spanish army, but by small groups of adventurers—artisans, traders, gentry, and peasants—who operated independently under

1935-458: A period of stagnation and limited development in the 1970s and 1980s. The agriculture sector employs 30% of Peru's population and accounts for 13% of GDP and more than 10% of total exports (US$ 1.6 billion in 2005). Two-thirds of agricultural GDP is produced on the Pacific coastal strip, a region totally dependent on irrigation due to low rainfall. High-value crops and irrigation technology have had

2064-892: A result of the marriage politics of the Catholic Monarchs (in Spanish, Reyes Católicos ), their Habsburg grandson Charles inherited the Castilian empire in the Americas and the possessions of the Crown of Aragon in the Mediterranean (including all of south Italy ), lands in Germany, the Low Countries , Franche-Comté , and Austria , starting the rule of the Spanish Habsburgs. The Austrian hereditary Habsburg domains were transferred to Ferdinand ,

2193-654: A surprise attack in Cajamarca that resulted in the massacre of thousands of Incas. This conquest facilitated the establishment of the Viceroyalty of Peru in 1542, allowing Spain to exert control over territories in western South America, comprising present-day Peru, Bolivia, Ecuador, and parts of Chile and Argentina. In the subsequent years, Spanish explorers and conquistadors ventured into northern South America, where they established settlements in present-day Venezuela and Colombia. Philip II of Spain (r. 1556–98) oversaw

2322-673: A surviving heir, probably the Crown of Aragon would have been split from Castile, which was inherited by Charles, Ferdinand and Isabella's grandson. Ferdinand joined the League of Cambrai against Venice in 1508. In 1511, he became part of the Holy League against France, seeing a chance at taking both Milan —to which he held a dynastic claim—and Navarre . In 1516, France agreed to a truce that left Milan in its control and recognized Spanish control of Upper Navarre , which had effectively been

2451-604: Is equipped with improved on-farm irrigation systems. Peru has a high availability of water resources with about 106 river basins, and a per capita availability of 77,600 m3—the highest in Latin America. The Andes divide Peru into three natural drainage basins : (i) Pacific basin, with 53 rivers, (ii) Atlantic basin, with 32 rivers, and (iii) Titicaca basin, with 13 rivers. The dry Pacific basin, with 37 million cubic meters (m3) available per year, contains just 1.8% of Peru's water resources. Some 53 rivers, flowing west from

2580-607: Is undertaking several programs aimed at addressing key challenges in the irrigation sector like increasing water stress, competing interests, deteriorating water quality, poor efficiency of irrigation, drainage systems (including low technology systems and underutilization of existing infrastructure), weak institutional and legal frameworks, low cost recovery (i.e., operation and maintenance costs above actual collections), and vulnerability to climate variability and change , including extreme weather conditions and glacier retreat . Agriculture in Peru dates back more than 5,000 years when

2709-470: Is used for irrigation, yet much of this water (65%) is lost due to reliance on inefficient irrigation systems. Overall efficiency of water use in irrigation systems is estimated at 35%, which is considered poor performance and is due mainly to leaky distribution systems and the wide use of unimproved gravity and flooding irrigation methods with an overall estimated efficiency of 50%. Water is rarely metered and fees are mostly based on hectarage rather than on

2838-435: The arbitristas . The natural resource abundance provoked a decline in entrepreneurship as profits from resource extraction are less risky. The wealthy preferred to invest their fortunes in public debt ( juros ). The Habsburg dynasty spent the Castilian and American riches in wars across Europe on behalf of Habsburg interests, and declared moratoriums (bankruptcies) on their debt payments several times. These burdens led to

2967-789: The American Revolutionary War , Britain ceded both Floridas back to Spain as part of the Treaty of Paris . Spain had recaptured West Florida in 1781 through military operations. Both Floridas were ceded to the United States in 1819 as part of the Adams-Onís Treaty . Louisiana was ceded back to France in 1801 in the Treaty of Aranjuez . The Bourbon monarchy implemented reforms like the Nueva Planta decrees , which centralized power and abolished regional privileges. Economic policies promoted trade with

The settlement gave spoils to those who had backed a Habsburg for the Spanish monarchy, ceding European territory of the Spanish Netherlands , Naples , Milan , and Sardinia to Austria ; Sicily and parts of Milan to the Duchy of Savoy , and Gibraltar and Menorca to the Kingdom of Great Britain . The treaty also granted British merchants

7611-826: The administration of water tariffs in one particular irrigation district. WUBs consist of representatives of Irrigation Commissions (Comisiones de Regantes) and non-agricultural water users groups which are responsible for water distribution in their irrigation subsectors and must participate financially in the planning and maintenance of the collective irrigation infrastructure. WUBs elect a board of directors to administer financial resources and implement WUB agreements and dispositions. WUBs face several challenges: (i) increased pressure of water resources due to competing demands, (ii) deteriorating irrigation infrastructure, (iii) lack of financial sustainability, (iv) lack of technical capacity to manage irrigation, and (v) ambiguous role of Juntas, Commission, and Committees among themselves and with

The fall of Tenochtitlan marked the beginning of Spanish colonial rule in Mexico, leading to the establishment of the Viceroyalty of New Spain in 1535. In 1532, Francisco Pizarro conquered the Inca Empire by capturing its leader Atahualpa during

8643-706: The coast. The 20th Century represented a period of agricultural stagnation especially during the 1970s and 1980s. In the past 30 years, the Peruvian Government has invested about US$ 5 billion to improve hydraulic infrastructure, including dams, and irrigation and drainage systems, producing an increase of the land under irrigation mostly in the coastal region. Today, approximately 1.7 million hectares of Peru's cultivated hectares have some irrigation infrastructure available. However, only 1.2 million hectares are actually irrigated each year due to poor performance of irrigation systems. The 20th century began with an important institutional development in Peru's irrigation sector with

His victory in the War of the Portuguese Succession led to the annexation of Portugal in 1580, effectively integrating its overseas empire—encompassing coastal Brazil and African and Indian coastal enclaves—into Spain's domain. Philip II also reaffirmed Spanish control over

9030-420: The country. The coastal region, an arid but fertile land, has about two-thirds of Peru's irrigation infrastructure due to private and public investment aimed at increasing agricultural exports. The Highlands and Amazon regions, with abundant water resources but rudimentary irrigation systems, are home to the majority of Peru's poor, many of whom rely on subsistence or small-scale farming. The Peruvian Government

9159-552: The creation of the Mining and Water Engineering Body (1904) and the Hydrological Service (1911). However, it was not until the 1920s that the first large-scale State irrigation projects were launched. Public investment in irrigation in 1905 accounted for 8.7% of the total, reaching 18.62% in 1912, a trend that continued in the 1920s and 1930s. From 1945 to 1948, the Government approved a National Plan for Improving Irrigation. Between 1945 and 1956, public investment reached unprecedented levels with up to 50% of total investment. Examples of

9288-481: The crown's encomienda system. Defying the opposition of Diego Velázquez de Cuéllar , the governor of Hispaniola, Hernán Cortés organized an expedition of 550 conquistadors and sailed for the coast of Mexico in March 1519. The Castilians defeated a 10,000-strong Chontal Mayan army at Potonchán on 24 March and emerged triumphant against a larger force of 40,000 Mayans three days later. On 2 September, 360 Castilians and 2,300 Totonac Indigenous allies defeated

9417-588: The dam is transferred via the tunnel to the Olmos River where it will be used to irrigate 5,500 hectares (14,000 acres) of land. From there, water continues down the Olmos River where at two points, it will be used at hydroelectric power stations. At the base of the valley, water will settle in the Palo Verde Reservoir which will have a storage capacity of 790 million cubic metres (28 × 10 ^  cu ft). The Palo Verde Dam will serve as

9546-550: The decisive Battle of Guinea . The Treaty of Alcáçovas (4 September 1479), while assuring the Castilian throne to the Catholic Monarchs, reflected the Castilian naval and colonial defeat: "War with Castile broke out waged savagely in the Gulf [of Guinea] until the Castilian fleet of thirty-five sail was defeated there in 1478. As a result of this naval victory, at the Treaty of Alcáçovas in 1479 Castile, while retaining her rights in

9675-677: The detriment of interests in the colonies, undermined creole elites' loyalty to the crown. When French forces of Napoleon Bonaparte invaded the Iberian peninsula in 1808, Napoleon ousted the Spanish Bourbon monarchy, placing his brother Joseph Bonaparte on the Spanish throne. There was a crisis of legitimacy of crown rule in Spanish America, leading to the Spanish American wars of independence (1808–1826). The Spanish Bourbons' broadest intentions were to reorganize

9804-490: The easternmost parts of Asia. The Treaty of Tordesillas was confirmed by Pope Julius II in the bull Ea quae pro bono pacis on 24 January 1506. The Treaty of Tordesillas and the treaty of Cintra (18 September 1509) established the limits of the Kingdom of Fez for Portugal, and the Castilian expansion was allowed outside these limits, beginning with the conquest of Melilla in 1497. Other European powers did not see

9933-486: The exclusive right to sell slaves in Spanish America for thirty years, the asiento de negros , as well as licensed voyages to ports in Spanish colonial dominions and openings. Spain's economic and demographic recovery had begun slowly in the last decades of the Habsburg reign, as was evident from the growth of its trading convoys and the much more rapid growth of illicit trade during the period. (This growth

10062-455: The expanding empire became an administrative issue. The reign of Ferdinand and Isabella began the professionalization of the apparatus of government in Spain, which led to a demand for men of letters ( letrados ) who were university graduates ( licenciados ), of Salamanca , Valladolid , Complutense and Alcalá . These lawyer-bureaucrats staffed the various councils of state, eventually including

10191-564: The face with the letter "G" (for guerra, the Spanish word for "war") and enslaved by the Spanish, or sacrificed and eaten by the Tlaxcalans. Cortés returned to Tenochtitlan in 1521 with a new invasion force and laid siege to the Aztec capital in May, which was suffering from a smallpox epidemic that killed thousands. The new emperor, Cuauhtémoc , defended Tenochtitlan with 100,000 warriors armed with slings, bows, and obsidian clubs . The first military encounter occurred after an advance along

10320-662: The fields by gravity irrigation (822473 ha) and 3% by pressurized irrigation (19680 ha). In the Costa landholdings are relatively large and agriculture is mostly commercialized and devoted to exports. In the Sierra and Selva, with 97% of Peru's water availability, surface water supplies agricultural fields by furrow irrigation. Irrigation systems consist of an open canal network, generally unlined, with rudimentary water intakes and distribution systems supplying small plots devoted mostly to subsistence agriculture. Less than 5% of irrigated land

10449-518: The fifteenth century. Its rival Castile laid claim to the Canary Islands (1402) and retook territory from the Moors in 1462. The Christian rivals Castile and Portugal came to formal agreements over the division of new territories in the Treaty of Alcaçovas (1479), as well as securing the crown of Castile for Isabella whose accession was challenged militarily by Portugal. Following the voyage of Christopher Columbus in 1492 and first major settlement in

10578-617: The foundation of the Spanish monarchy. The union of the Crowns of Castile and Aragon joined the economic and military power of Iberia under one dynasty, the House of Trastámara . Their dynastic alliance was important for a number of reasons, ruling jointly over a number of kingdoms and other territories, mostly in the western Mediterranean region, under their respective legal and administrative status. They successfully pursued expansion in Iberia in

10707-574: The highlands as well. According to 2000 data, the National Government invested US$ 3.468 million to develop irrigation schemes in ten coastal projects. Minor irrigation infrastructure is financed by the National Government in collaboration with the beneficiaries through a cost-sharing system. Since the creation of the Technical Irrigation Program (under PSI), financially sustainable WUBs have improved 5,282 ha of irrigation infrastructure, benefiting 1,085 producers, by raising US$ 5.5 million of

10836-424: The highlands. The 1969 agrarian reform expropriated all estates above a certain size, usually 100 hectares. Most Peruvian peasants were independent smallholders and thus continued to farm their land individually after the reforms. The agrarian reform and political instability contributed to the poor performance of agriculture, since they profoundly changed the relationships of production in the countryside, disrupted

10965-630: The highlands. The National Meteorological and Water Resources Service ( Servicio Nacional de Meteorologia e Hidrologia- SENAMHI ) studies and disclosures information regarding climate events and their impacts on water resources. In 2008, Peru's government created a National Water Authority ( Autoridad Nacional del Agua , ANA), under MINAG, replacing the Intendancy of Water Resources. ANA is responsible for designing and implementing sustainable water resources policies and irrigation nationally. ANA has local offices at each of Peru's 14 hydrographic regions,

11094-525: The improvements were in and around some major coastal cities and the major islands such as Cuba, with its tobacco plantations , and a renewed growth of precious metals mining in South America. Agricultural productivity remained low despite efforts to introduce new techniques to what was for the most part an uninterested, exploited peasant and laboring groups. Governments were inconsistent in their policies. Though there were substantial improvements by

11223-556: The institutions of empire to better administer it for the benefit of Spain and the crown. It sought to increase revenues and to assert greater crown control, including over the Catholic Church. Centralization of power (beginning with the Nueva Planta decrees against the realms of the Crown of Aragon ) was to be for the benefit of the crown and the metropole and for the defense of its empire against foreign incursions. From

11352-499: The integrity of the closed Spanish mercantile system and established thriving sugar colonies. At the beginning of his reign, the first Spanish Bourbon, King Philip V, reorganized the government to strengthen the executive power of the monarch as was done in France, in place of the deliberative, Polysynodial System of Councils. Philip's government set up a ministry of the Navy and the Indies (1714) and established commercial companies,

11481-525: The irrigation infrastructure in coastal areas is managed by 64 WUBs, comprising about 300,000 water users. WUBs are less developed in the Andes and the Amazon, where water for irrigation is managed by more traditional organizations, Irrigation Committees (Comites de Regantes). WUBs are private, nonprofit, and collectively owned organizations responsible for the O&;M of collective irrigation infrastructure and

11610-510: The islands of Gran Canaria (1478–1483), La Palma (1492–1493), and Tenerife (1494–1496) were subjugated. By 1504, more than 90 percent of the indigenous Canarians had been killed or enslaved. The Portuguese tried in vain to keep secret their discovery of the Gold Coast (1471) in the Gulf of Guinea , but the news quickly caused a huge gold rush. Chronicler Pulgar wrote that the fame of

11739-526: The lands adjoining it for the Spanish Crown. The Catholic Monarchs had developed a strategy of marriages for their children to isolate their rival, France. The Spanish princesses married the heirs of Portugal, England and the House of Habsburg . Following the same strategy, the Catholic Monarchs decided to support the Aragonese house of the Kingdom of Naples against Charles VIII of France in

11868-427: The late 18th century, Spain was still an economic backwater. Under the mercantile trading arrangements it had difficulty in providing the goods being demanded by the strongly growing markets of its empire, and providing adequate outlets for the return trade. From an opposing point of view according to the "backwardness" mentioned above the naturalist and explorer Alexander von Humboldt traveled extensively throughout

11997-635: The mainland was Santa María la Antigua del Darién in Castilla de Oro (now Nicaragua , Costa Rica , Panama and Colombia ), settled by Vasco Núñez de Balboa in 1510. In 1513, Balboa crossed the Isthmus of Panama , and led the first European expedition to see the Pacific Ocean from the West coast of the New World. In an action with enduring historical import, Balboa claimed the Pacific Ocean and all

12126-580: The major actor in irrigation development which focused on the coastal region. Some 76% of investment in the coastal region between 1978 and 1982 was concentrated in three major irrigation projects at Majes ( Arequipa Region ), Chira-Piura ( Piura Region ) and Tinajones ( Lambayeque Region ). This trend was maintained in the 1990s. In 1996 the government created the Subsectoral Irrigation Program (Programa Subsectorial de Irrigacion – PSI), aiming to develop some WUBs' capacities, reduce

12255-609: The mid-1820s, Spain had lost its territories in Mexico, Central America, and South America. By 1900, it had also lost Cuba , Puerto Rico , the Philippine Islands , and Guam in the Mariana Islands following the Spanish–American War . With the marriage of the heirs apparent to their respective thrones Ferdinand of Aragon and Isabella of Castile created a personal union that most scholars view as

12384-560: The national, regional, and local levels. PSI ( Programa Subsectorial Irrigacion ), is the institution carrying out the PSI programs aimed at improving the WUBs' managerial and technical capacities. The National Watershed Management and Conservation Soils Project ( Programa Nacional de Manejo de Cuencas Hidrograficas y Conservacion del Suelo- PRONAMACHCS ), promotes integrated water resources management and conservation in river basins, with emphasis on

12513-433: The newest responsibilities of these bodies consists of the implementation of the Technical Irrigation Program and the operation and maintenance (O&M) of major public hydraulic infrastructure (i.e. headwork such as dams and inter-basin transfers transferred to them as part of the decentralization process). Water User Boards (WUBs) responsible for operation and maintenance (O&M) of minor irrigation infrastructure. Finally,

12642-607: The newly approved Water Resources Law (Ley de Recursos Hídricos – LRH, published March 31, 2009) includes River Basin Councils (Consejos de Recursos Hidricos de las Cuencas, CC) as part of the National Water Resources System. The CCs will be in charge of elaborating River Basin Plans including allocation of water to different users and planning of new infrastructure which will impact irrigation. There are

12771-939: The organization of productive systems on the best agricultural lands, and forced out part of the entrepreneurial capacity. The agrarian reform and the General Water Law (1969) made the existing informal water users organizations official and part of an organizational model promoted by the state. In 1989, the decree 037-89-AG (Decreto Supremo) decentralized operational, maintenance, and management of irrigation systems to water user boards (Juntas de Usuarios-WUBs). The decree aimed to incorporate private investment and spur independence and financial sustainability within water user organizations by establishing water tariffs to cover operational and maintenance costs (O&M). However, low tariffs and collection capacity produced insufficient financial support for WUBs to maintain and develop irrigation systems. The Peruvian Government continued to be

12900-499: The papal bull Æterni regis (dated on 21 June 1481). However, this experience would prove to be profitable for future Spanish overseas expansion, because as the Spaniards were excluded from the lands discovered or to be discovered from the Canaries southward —and consequently from the road to India around Africa —they sponsored the voyage of Columbus towards the west (1492) in search of Asia to trade in its spices , encountering

13029-569: The poorest areas, most of them in the southern Andes. Rural and Urban Poverty by Natural Regions in Peru (%) Source : INEI 2001 Peru's agricultural land is only 4.3% of its territory, with 5.5 million ha in use, of which 3.75 million ha is under rainfed agriculture and 1.75 million ha with irrigation infrastructure. The following chart reflects irrigation infrastructure allocation in Peru. Area with Irrigation Infrastructure and irrigated areas (In thousands of hectares) Source : Portal Agrario (1994) About 80% of all water withdrawal in Peru

13158-401: The process or in need of assistance to achieve financial and technical sustainability. Tariffs fluctuate from US$ 20–30 per ha, and collection rates vary from 10% in the Amazon to 68% in the Costa region. The majority (83%) of the tariff revenues fund WUB activities. The remaining returns are allocated to cover O&M costs (8%) and to support the regional water authority, ATDR (8%). In 2006,

13287-483: The profitability and competitiveness of irrigated agriculture through sustainable use of land and efficient water use. The strategy aims at increasing water use efficiency through the rehabilitation and modernization of irrigation infrastructure and the improvement of its O&M; promoting equitable and sustainable water use through the technical improvement of irrigation and drainage infrastructures; developing technically and financially self-sufficient WUBs responsible for

13416-652: The projects implemented at this time and during the 1960s are the water transfers from the Quinoz River to the intermittent Piura River in the Piura Region and from the Chotano River to Chancay-Lambayeque River in the Lambayeque Region , both located in the northern part of the coastal plain. Between 1950 and 1980, 90% of irrigation investment was directed to the coastal region and only 10% to

13545-521: The rainfall occurs between November and May; the rest of the year irrigation depends on low-tech systems. Source : INEI (2007) Environmental effects of irrigation concern: The environmental effects often impoverish tail-end farmers. Loss of habitat , water pollution and downstream effects have been scarcely looked at, because insufficient economic resources have limited the involvement of institutions responsible for environmental preservation. The most encompassing survey of soil salinity problems

13674-486: The river. The tunnel was completed on 20 December 2011 with a ceremony attended by Peru's President Ollanta Humala . In June 2010, H2Olmos S.A. was awarded the contract for the irrigation system and it is expected to be operational in 2013. The contract for the hydroelectric component, which is planned to consist of two power stations, was awarded to Sindicato Energético S.A. in June 2010. The water transfer accomplished by

13803-640: The role of the public sector in irrigation, improve sustainability through increased cost recovery, and increase investment in technical improvement of irrigation systems. The project, considered a big success, expanded to all WUBs in the Costa and is in the process of being expanded to the Sierra. According to The Economist , Peru is South America's fastest-growing economy. That performance owes much to record prices for mineral exports. However, newer export products, such as mangoes and artichokes, are also flourishing. Irrigated agriculture has become increasingly important in Peru's development and growth, especially after

13932-403: The rural Bajío faced rising land prices, falling wages. Eviction of many from their lands resulted. With a Bourbon monarchy came a repertory of Bourbon mercantilist ideas based on a centralized state, put into effect in the Americas slowly at first but with increasing momentum during the century. Shipping grew rapidly from the mid-1740s until the Seven Years' War (1756–63), reflecting in part

14061-628: The same amount of bread as any European city, with 363 kilograms of bread per person per year in comparison to the 377 kilograms consumed in Paris. Caracas consumed seven times more meat per person than in Paris. Von Humboldt also said that the average income in that period was four times the European income and also that the cities of New Spain were richer than many European cities. Bourbon institutional reforms under Philip V bore fruit militarily when Spanish forces easily retook Naples and Sicily from

14190-613: The success of the Bourbons in bringing illicit trade under control. With the loosening of trade controls after the Seven Years' War, shipping trade within the empire once again began to expand, reaching an extraordinary rate of growth in the 1780s. The end of Cádiz's monopoly of trade with the American colonies brought about very important changes, particularly a rebirth of Spanish manufactures. Most notable of those changes were both

14319-440: The thrones of the Crown of Aragon . The two became known as the Catholic Monarchs , with their marriage a personal union that created a relationship between the Crown of Aragon and Castile, each with their own administrations, but ruled jointly by the two monarchs. Ferdinand and Isabella defeated the last Muslim king out of Granada in 1492 after a ten-year war . The Catholic Monarchs then negotiated with Christopher Columbus ,

14448-411: The transfer of water rights, including irrigation, from one party to another, which is incompatible with the General Water Law, and presents significant obstacles to the establishment and management of water property rights. In 2003 the government approved a 10-year National Irrigation Strategy (Ministerial Resolution 0498-2003-AG) aims at improving irrigation and drainage system technologies by creating

14577-535: The treasures of Guinea "spread around the ports of Andalusia in such way that everybody tried to go there". Worthless trinkets, Moorish textiles, and above all, shells from the Canary and Cape Verde islands were exchanged for gold, slaves, ivory and Guinea pepper. The War of the Castilian Succession (1475–79) provided the Catholic Monarchs with the opportunity not only to attack the main source of

14706-477: The treaty between Castile and Portugal as binding on themselves. Francis I of France observed "The sun shines for me as for others and I should very much like to see the clause in Adam's will that excludes me from a share of the world." Spanish settlement in the New World was based on a pattern of a large, permanent settlements with the entire complex of institutions and material life to replicate Castilian life in

14835-510: The usual legal considerations that need to be checked when developing PPPs in any sector, such as legal restrictions on the type of PPP arrangement that can be entered into, relevant procurement rules for entering into PPPs, existence of restrictions on foreign investment, taxation and potential for tax holidays and the ability to assign rights such as security and step in rights to lenders. There are 112 WUBs in Peru comprising about 1,500 Irrigation Commissions (Comisiones de Regantes–CIs). Most of

14964-915: The viewpoint of Spain, the structures of colonial rule under the Habsburgs were no longer functioning to the benefit of Spain, with much wealth being retained in Spanish America and going to other European powers. The presence of other European powers in the Caribbean, with the English in Barbados (1627), St Kitts (1623–25), and Jamaica (1655); the Dutch in Curaçao , and the French in Saint Domingue (Haiti) (1697), Martinique , and Guadeloupe had broken

15093-493: The volume of water used. Inadequate irrigation management together with inefficient irrigation systems lead to pervasive irrigation practices, with farmers applying water in excess of crop requirements and water availability. The coastal region, due to climatic conditions, depends on the water supplied by rivers (surface water) of the Andean Chain channeled through irrigation systems. In 1997, surface water supplied 97% of

15222-709: The war. In 1742, the War of Jenkins' Ear merged with the larger War of the Austrian Succession , and King George's War in North America. The British, also occupied with France, were unable to capture Spanish convoys, and Spanish privateers captured British merchant shipping along the Triangle Trade routes and attacked the coast of North Carolina , levying tribute on the inhabitants. In Europe, Spain had been trying to divest Maria Theresa of

15351-400: The world average. Decentralization, together with the development of water resources management and irrigation institutions, created a multitude of entities responsible for irrigation investments at the national, regional, and local levels. The National Government has been investing in major irrigation infrastructure, mostly located in the coastal region although it plans to extend its efforts to

15480-529: Was a century of prosperity for the overseas Spanish Empire as trade within grew steadily, particularly in the second half of the century, under the Bourbon reforms. Spain's victory in the Battle of Cartagena de Indias against a British expedition in the Caribbean port of Cartagena de Indias helped Spain secure its dominance of its possessions in the Americas until the 19th century. But different regions fared differently under Bourbon rule, and even while New Spain

15609-547: Was also a considerable increase of the amount of water applied per ha of irrigated land that shows the possibility of using excessive irrigation. Including double cropping in a year   due to waterlogging and salinity Sources : (1) CENDRET, 1974 ”Evaluación de los problemas de drenaje y salinidad en la costa Peruana”, (2) IPROGA, 1988 ”Gestión del Agua y Crisis Institucional”, (3) INADE, 2002 “Plan de Gestión de la Oferta de Agua de los proyectos Hidráulicos de costa“. Drainage problems are also affecting 150,000 hectares in

Following the war, the new Bourbon monarchy took a much more cautious approach to international relations, relying on a family alliance with Bourbon France, and continuing to follow a program of institutional renewal. The crown program to enact reforms that promoted administrative control and efficiency in the metropole to

From there Juan Ponce de León conquered Puerto Rico (1508) and Diego Velázquez took Cuba . Columbus encountered the mainland in 1498, and the Catholic Monarchs learned of his discovery in May 1499. The first settlement on

15996-578: Was non-existent, their conditions were much better than any other peasant or farmer in northern Europe . Humboldt also published a comparative analysis of bread and meat consumption in New Spain compared to other cities in Europe such as Paris. Mexico City consumed 189 pounds of meat per person per year, in comparison to 163 pounds consumed by the inhabitants of Paris, the Mexicans also consumed almost

16125-402: Was particularly prosperous, it was also marked by steep wealth inequality. Silver production boomed in New Spain during the 18th century, with output more than tripling between the start of the century and the 1750s. The economy and the population both grew, both centered around Mexico City. But while mine owners and the crown benefited from the flourishing silver economy, most of the population in

16254-428: Was realized in the period of 1971 to 1975 by ONERN with collaboration of CENDRET, later SUDRET. The following table shows irrigation developments, cultivated and degraded areas in particular years from 1964 to 2000 in the coastal zone. It shows the fast development of irrigation water resources and irrigable land, the lagging behind of the actually cultivated land and the fast increase of degraded land. Up to 1984 there

16383-481: Was slower than the growth of illicit trade by northern rivals in the empire's markets.) However, this recovery was not then translated into institutional improvement, rather the "proximate solutions to permanent problems." This legacy of neglect was reflected in the early years of Bourbon rule in which the military was ill-advisedly pitched into battle in the War of the Quadruple Alliance (1718–20). Spain

16512-507: Was the first document to establish an administrative organization in the Indies. Columbus' discoveries began the Spanish colonization of the Americas . Spain's claim to these lands was solidified by the Inter caetera papal bull dated 4 May 1493, and Dudum siquidem on 26 September 1493. Since the Portuguese wanted to keep the line of demarcation of Alcaçovas running east and west along

16641-516: Was the lifeblood of the Habsburg empire declined in proportion to registered shipping (a shipping registry having been established in 1735). Two upheavals registered unease within Spanish America and at the same time demonstrated the renewed resiliency of the reformed system: the Tupac Amaru uprising in Peru in 1780 and the rebellion of the comuneros of New Granada , both in part reactions to tighter, more efficient control. The 18th century
