The objective of this study is to carry out a survey of the different studies that have been carried out in Cuba in terms of ecosystem services valuation. It is a path little traveled and on rise that requires the detection of its strengths and gaps as a guide to the execution of said investigations with de human capital that the country possesses. A total of 42 papers were compiled, including 14 scientific articles, 8 diploma theses, 15 doctoral theses and 5 master´s theses. The ecosystem services most evaluated were those of fibre and food supply, the regulation of climate, water, natural hazard and air quality and within cultural services, aesthetic values and recreation and ecotourism.

We calculate emissions of criteria pollutants (VOC's, PM10, CO, NOx and SOx) from point sources for the year 1997 in Cali-Yumbo (Colombia). Data were obtained from 108 emission declarations to environmental authorities. We applied the method of emission factors for most of the sources which had no direct measurements and reported type and amount of fuel used. We find that paper manufacturing and printing/publishing industries generate the most pollutants overall, followed by non-metallic minerals and textile/apparel industries. While the sources in the city of Cali were responsible for most of the volatile organic compounds (VOC's), emissions of sulfur oxides and particulate matter originate mostly from sources in the industrial town of Yumbo.

This paper is proposes a procedure for comparative internal and external risk of management to control the atmospheric emission, which are provoked by steam boiler of service sectors. This are located at different points of the urban zone, with are considered as combustion fixes sources. The proposal takes the most actuality legal and standard documents about the subject as a base. This procedure pays attention to the risk management related to planning, technology, operation and effect of the atmospheric pollution, in order to compare the potential risk and the priority in a making decision processes, in a control action and improvement plan, to achieve the mitigation of effect the atmospheric pollution in Cienfuegos city, Cuba.

This paper aims to illustrate a study about air quality from mid-sized cities in the South of Chile. The main cause for air pollution in medium-sized cities is the high consumption of wet, low-quality firewood that produces fine particulate material capable of penetrating the respiratory tract. An analysis on how this pollution is affecting the population is implemented; for this purpose, a statistical analysis was applied to a monitoring station in Chillán's city (from 2008 to 2013). This study leads to the conclusion that in Chillán the population is exposed to harmful particulate matter almost all year long. Emphasis is made on the need to maintain a time database, as complete as possible, in order to develop good forecasting models to inform authorities of situations in which the regulations for such material are exceeded.

The aim of this paper is to develop an analysis of mitigation and adaptation strategies in the transport sector in the city of Mexicali, Baja California, Mexico. Based on the methodology of the Programs of Action on Climate Change (PACC), we analyzed the Mexicali emissions inventory and generated a diagnosis. Once we analyzed the current situation, we studied mitigation strategies such as Bus Rapid Transit (BRT), the smog check, new importation legislation for used cars, biofuel production, the promotion of loweremission vehicles and urban planning. On adaptation strategies vehicle recycling and the use of non-moto-rized transport were studied as an alternative of sustainable mobility. [ABSTRACT FROM AUTHOR]

Chile has pioneered the implementation of emission offseting programs pursuing simultaneously economic growth and environmental protection. In this paper, emission trading programs implemented in Santiago of Chile are analyzed and its relevance for developing countries is evaluated. It is argued that emission trading programs can be the best tool to deal with air pollution problems even in cases in which the institutional capacities are not well developed. Moreover, the inclusion of the transport system into the emission trading programs and the possibility of moving towards a system of interpollutant exchange are both nouvelle and relevant elements in the context of air pollution control policies. However, these innovations involve rather more complex elements in the design of emission trading programs. [ABSTRACT FROM AUTHOR]
