The social-ecological system of wetlands supports biodiversity and enhances the mental well-being of urban inhabitants. However, wetlands in Latin America face pressures from urban expansion, agriculture, governance conflicts, and poorly enforced regulations driven by economic activities, resulting in biodiversity loss and diminished ecosystem services. This study applies the social-ecological system framework to identify ecosystem services and evaluate factors influencing collective actions and governance effectiveness for urban and peri-urban wetlands. The case study is based in Cali, Colombia, using 33 semi-structured interviews, document analysis, and field visits. We find that facilitators such as leadership, networking, social capital, and community-based rules drive positive outcomes, enhancing ecosystem services. In contrast, barriers to collective action in wetland governance include low resource dependence, diverse actors, exclusion of groups, large resource size, pollution, conflicts, and property-rights issues, leading to ecosystem degradation. Additionally, our research shows how ecosystem services are influenced by environmental conflicts, property-rights systems, and community-led initiatives. Collaboration between communities and public agencies is crucial, enhancing local governance efficiency and ecosystem services. [ABSTRACT FROM AUTHOR]

Urban growth has impacted natural ecosystems such as wetlands. This situation destabilizes the beneficial contributions of nature, generating a socioeconomic effect. There is a need to quantify the benefits of wetlands in developing countries and urban areas, where the growth of cities is fastest. This is the first valuation study of urban and peri-urban wetlands in Colombia. The methodology includes a benefit transfer (BT) method with a geographical information system (GIS) and an exploratory governance analysis. Because there are few studies on the economic valuation of urban wetlands in Latin America, we present a methodology of interest, which can be easily replicated in other cities of this subcontinent. Based on an economic approach, our results find that 76% of the total value of wetlands is provided by ecosystem services (ES) of existence and legacy value, followed by maintenance of the life cycle of migratory species and water supply. Urban areas are identified where users benefit more than areas where the population exerts greater pressure on wetlands. Weak governance is due to the disarticulation between regulation, land-use planning, and the social-ecological system. This research contributes to urban wetland management policies, as well as to sustainable solutions in cities. [ABSTRACT FROM AUTHOR]

This article presents new evidence on the economic links between Asia and Latin America. Estimates from a Bayesian vector autoregression model show that key macroeconomic variables of the Pacific Alliance countries (Mexico, Peru, Chile, and Colombia) have a significant response to shocks on Emerging Asia's demand. The spillover effects show that Peru is the country that is most vulnerable to income shocks in Emerging Asia. Nevertheless, developed economies' shocks are still significant when it comes to explain the macroeconomic performances of Colombia, Chile, and especially, Mexico. [ABSTRACT FROM AUTHOR]

This paper employs a multivariate constant conditional correlation (CCC) GARCH model and the VAR-AGARCH model to examine whether the U.S. equity and money market have a volatility spillover effect on the returns of the most important agricultural export products of Latin America over the turbulent 2005–2016 period. These results indicate the strengthening of crossmarket linkages between U.S. equity and money market and agricultural raw material commodities (notably sugar and soy) during the period of an upward trend and financial turmoil.

The purpose of this article is to improve the empirical evidence on commodity prices in various dimensions. First, we attempt to identify the extent of comovements in 44 monthly nonenergy commodity price series in order to ascertain whether the increase in comovement is a recent term phenomenon. Second, we attempt to determine the role of uncertainty in determining comovements among nonenergy prices in the short run. We diagnose the overall comovement using a dynamic factor model estimated by principal components. A factor-augmented vector autoregressive approach is used to assess the relationship of fundamentals, financial and uncertainty variables with the comovement in commodity prices. We find a greater synchronization among raw materials since December 2003. Since that date, uncertainty has played an important role in determining short-run fluctuations in nonenergy raw material prices. [ABSTRACT FROM AUTHOR]

This paper identifies and assesses the economic value of the main natural benefits relating to the complex system of wetlands (CSW) belonging to the San Juan River in the Colombian Magdalena Medio. This is a region rich in biodiversity and natural resources, which in the past was hit by violence and the actions of different armed groups. Benefit estimation takes into account diverse monetary valuation techniques, such as market prices for direct wetland uses and the transfer of benefits, for the assessment of indirect use and non-use values. The results reveal that the most important values relate to ecotourism (60.1%) as a possible future use of the CSW, the benefit of preventing flooding (28.4%), and the biodiversity that inhabits the area (6.7%). All three values represent the total economic value of the CSW. This research also finds that the benefits of the ecosystems currently provided by the CSW exceed the opportunity cost, represented by the total conversion of the area to livestock. Lastly, the net present value (NPV) of 25 and 75 years, relating to the benefits of the CSW, exceeds the income from the conversion of land to livestock, revealing profitable investments in conservation and ecotourism projects.
