17.2 Present Situation and Outlook of Regional Integration Investments
17.2 Present Situation and Outlook of Regional Integration Investments and exports in the North Zone will be largely determined by the degree to which the macro-region is physically and institutionally integrated. At present, it is highly important to facilitate physical integration through the improvement of infrastructure and the transport system of export corridors. Institutional integration, e.g., standardized customs procedures, foreign investment laws, taxation systems, etc., is no less important than physical integration. Such development will widen and strengthen relations among economies of the macro-region and increase the possibility of handling export and import cargo and receiving foreign investment in the North Zone. Enterprises in the zone may also benefit from economies of scale while consumers will enjoy increases in the variety of goods and services available due to an expansion of their market. Cooperation between the private and public sectors and among central and local governments in the macro-region is indispensable for physical and institutional integration. This is because neither the private sector, nor the Chilean or regional governments of the North Zone, can carry out all necessary tasks alone. When the public sector renders support to improve physical and institutional infrastructure, particularly through international and inter-regional cooperation, the private sector’s interest in investing in the macro-region will be significantly increased. This will happen because such a situation will help investors minimize economic and political risks and maximize profits. 17.2.1 Regional Integration Schemes Institutional arrangements that can facilitate trade and investment in the macro-region include a customs union, a common market, a free trade agreement, a free trade zone, etc., but these schemes for regional economic integration are not new in South America.

Abstract: This review aims to understand the environmental impact that tailings produce on the land and marine ecosystem. Issues related to flora, fauna, and the environment are revised. In the first instance, the origin of the treatment and disposal of marine mining waste in Chile and other countries is studied. The importance of tailings’ valuable elements is analyzed through mineralogy, chemical composition, and oceanographic interactions. Several tailings’ treatments seek to recover valuable minerals and mitigate environmental impacts through leaching, bioleaching, and flotation methods. The analysis was complemented with the particular legislative framework for every country, highlighting those with formal regulations for the disposal of tailings in a marine environment. The available registry on flora and fauna affected by the discharge of toxic metals is explored. As a study Citation: Rodríguez, F.; Moraga, C.; case, the “Playa Verde” project is detailed, which recovers copper from marine tailings, and uses Castillo, J.; Gálvez, E.; Robles, P.; Toro, phytoremediation to neutralize toxic metals.

Huemul Portfolio – Chile
Environmental and Social Review Summary (ESRS) Huemul Portfolio – Chile Original language of the document: English Revision’s cut-off date: March 2020 1. General Information and Overview of Scope of IDB Invest’s Review Mainstream Renewable Power (“The Sponsor” or “MRP”), through Huemul Energía Spa (“The Client”, “The Special Purpose Vehicle” or the “SPV”), is planning to develop the Huemul Renewable Energy Portfolio (“The Project”). The latter comprehends two Photovoltaic Power Plants (Pampa Tigre, located at Antofagasta region, and Valle Escondido, located at Atacama region), and three Wind Farm Plants (Ckani and Llanos del Viento, both located at Antofagasta region, and Puelche Sur located at Los Lagos region), hereafter “The Subprojects”. Each Subproject was subject to an environment evaluation1 under Chilean legislation, which concludes with a Resolution of Environment Qualification (the “RCA”), which is, in fact, an environmental license. Any modification or new work that might be needed after the RCA has been granted, can be evaluated through a Pertinence Consulting (“CP”), if such works do not impose new impacts; or through an environment assessment declaration (“DIA”) or an environmental impact assessment (“EIA”), depending in the magnitude and intensity of such impacts. Pampa Tigre Photovoltaic Power Plant (“Pampa Tigre”), evaluated through a DIA, includes: i) the installation of 430,920 photovoltaic modules with a gross installed capacity of 100 megawatt alternating current (“MWac”); ii) a booster substation; iii) a switch substation; iv) and a 9.6 km long, 220 kilo-volt (“kV”) transmission line (“TL”). Valle Escondido Photovoltaic Power Plant (“Valle Escondido”), evaluated through a DIA, includes: i) the installation of 382,000 photovoltaic modules that total a gross installed capacity of 105 MWac; and ii) a booster substation which will transfer the energy produced by the Project to the Sistema Eléctrico Nacional (“SEN”).

From north to south, the AFS has been subdivided into three major segments of brittle and ductile faults: the Salar del Carmen, the Paposo and the El Salado segments (Naranjo, 1987). In the last 10 years systematic studies of the northern-most segments have produced considerable progress on the understanding of the chronology and flow regime of the displacements associated with the activity of the AFS (Brown et al., 1993; Dallmeyer et al., 1996, Wilson and Grocott, 1999; Bonson, 1998). In particular, in the El Salado segment it has been shown that the AFS was initiated about 130 Ma ago as a left- transtensional strike-slip system and was active as a synplutonic fault to at least 106 Ma (Dallmeyer et al., 1996).

Regional Centers for Scientific And
REGIONAL Program CONICYT REGIONAL CENTERS FOR SCIENTIFIC AND TECHNOLOGICAL DEVELOPMENT Decentralizing science to serve the regions A joint initiative of CONICYT’s Regional Program and the regional governments REGIONAL PROGRAM 1 Comisión Nacional de Investigación 2 Científica y Tecnológica - CONICYT REGIONAL PROGRAM 3 The National Commission for Scientific and Technological Research, CONICYT was created in 1967 as an advisory organization for the Presidency in matters of scientific development. It is an autonomous public institution under the Ministry of Education. It organizes its work under two main strategic pillars: strengthening Chile’s scientific and technological base and promoting advanced human capital training. In order to achieve these strategic goals CONICYT has a variety of programs guided by the principles of open tendering and excellency via open calls. The projects are evaluated through different stages until their awarding, based on evaluations that follow international practices. Amongst our programs, the Regional Program for Scientific and Technological Research is of note. It began in 2000 thanks to an initiative by the Undersecretary of Regional Development and Administration. The instrument “Creation of regional centers for scientific and technological research” was co-funded by regional governments (GORE) with the aim of expanding and decentralizing the distribution of human, financial and material resources, from a geographic and institutional perspective. Thereby, the goal is to direct research towards the relevant subjects for the development of the regions where research institutions are located. Also, we hope to stimulate the development of disciplines or specific areas throughout the country with the purpose of helping the regional centers to become national leaders in their specific fields.
