The environmental Kuznets curve: The validity of its foundations in developing countries
La Curva de Kuznets Ambiental (CKA) ha sido probablemente el tópico más analizado
en la economía ambiental en los últimos años. Puntualmente, la hipótesis sostiene que
entre el producto y cualquier medida de contaminación plausible de ser utilizada como indicador de
degradación ambiental se verifica en el largo plazo una relación funcional con forma de U
invertida, por lo que el daño ambiental es una función creciente del nivel de actividad
económica hasta un determinado nivel crítico de renta a partir del cual mayores niveles de
renta se asocian a niveles progresivamente mayores de calidad ambiental. Sin embargo, varios
de los argumentos que sirven de sustento teórico a la hipótesis no resultan mayormente
operativos en las circunstancias económicas, sociales e institucionales propias de países
en desarrollo. En particular, la desigualdad en la distribución del ingreso y la fragilidad del
marco institucional en materia ambiental debilitan los principales fundamentos que sostienen
esta hipótesis, quitando relevancia a la conveniencia de esperar y crecer para alcanzar mejoras en la calidad ambiental.
En este contexto, el objetivo de este trabajo es revisar los argumentos teóricos que sirven de
soporte a la CKA y analizar las particularidades que los mismos enfrentan en el caso de países
en desarrollo, dejando en evidencia la importancia que la política ambiental adquiere en estos
últimos para mejorar las condiciones de vida de la poblaciónThe Environmental Kuznets Curve (EKC) has probably been the most discussed topic
in applied environmental economics over the last twenty years. The hypothesis states the
existence of an inverted U‑shaped relationship between economic growth and environmental
degradation, which involves that environmental damage increases with economic activity up to
a certain level of income, after which increases in income are associated to higher environmental
quality. However, many of the arguments that serve as a theoretical basis for the hypothesis are
not applicable to the economic, social and institutional circumstances of developing countries.
In particular, inequality in income distribution and the weakness of the institutional framework
in the environmental field weakens the main arguments that support the idea of the EKC,
making the desirability of waiting and growing to achieve improvements in environmental
quality less relevant.
In this context, the aim of this study is to present a review of the theoretical arguments
supporting EKC and to analyze the particularities they face in the case of developing countries,
showing the importance of the role played by environmental policy in the improvement of living conditions in these countrie
Uso de recursos hídricos en las actividades productivas del Municipio de General Pueyrredon, Buenos Aires
El agua es un recurso natural renovable, escaso y crítico para el desarrollo de la vida, por lo que también resulta estratégico. La disponibilidad natural de agua por habitante ha disminuido globalmente en un 30% en las últimas dos décadas debido al impacto del crecimiento poblacional, el cambio climático y el desarrollo económico (FAO, 2020). Dado este escenario y de acuerdo a la Agenda 2030 de la ONU, la consecución de diversos Objetivos de Desarrollo Sostenible demanda una urgente definición de esquemas de gestión sostenibles y equitativos para el uso y consumo del agua (ONU, 2018).Fil: Anrriquez Anlauf, Dulce Serena.

Engaging stakeholders across a socio-environmentally diverse network of water research sites in North and South America
Maintaining and restoring freshwater ecosystem services in the face of local and global change requires adaptive research that effectively engages stakeholders. However, there is a lack of understanding and consensus in the research community regarding where, when, and which stakeholders should be engaged and what kind of researcher should do the engaging (e.g., physical, ecological, or social scientists). This paper explores stakeholder engagement across a developing network of aquatic research sites in North and South America with wide ranging cultural norms, social values, resource management paradigms, and eco-physical conditions. With seven sites in six countries, we found different degrees of engagement were explained by differences in the interests of the stakeholders given the history and perceived urgency of water resource problems as well as differences in the capacities of the site teams to effectively engage given their expertise and resources. We categorized engagement activities and applied Hurlbert and Gupta's split ladder of participation to better understand site differences and distill lessons learned for planning comparative socio-hydrological research and systematic evaluations of the effectiveness of stakeholder engagement approaches. We recommend research networks practice deliberate engagement of stakeholders that adaptively accounts for variations and changes in local socio-hydrologic conditions. This, in turn, requires further efforts to foster the development of well-integrated research teams that attract and retain researchers from multiple social science disciplines and enable training on effective engagement strategies for diverse conditions

Can scenario-planning support community-based natural resource management? Experiences from three countries in latin america
Community Based Natural Resource Management (CBNRM) is a concept critical to managing socio-ecological systems, but whose implementation needs strengthening. Scenario-planning is one approach that may offer benefits relevant to CBNRM, but whose potential is not yet well understood. We therefore designed, trialled and evaluated a scenario-planning method intended to support CBNRM at three cases, located in Colombia, Mexico and Argentina. Implementing scenario-planning was judged as worthwhile in all three cases, although aspects of it could be challenging to facilitate. The benefits generated were relevant to strengthening CBNRM: encouraging the participation of local people and using their knowledge; enhanced consideration and adaption of future change; and supporting the development of systems thinking. Tracing exactly when and how these benefits arise is challenging, but two elements of the method seemed particularly useful. Firstly, using a systematic approach to discuss how drivers of change may affect local socio-ecological systems helped to foster systems thinking and identify connections between issues. Secondly, explicitly focusing on how to use and respond to scenarios helped identify specific practical activities ('response options') that would support CBNRM despite the pressures of future change. Discussions about response options also highlighted the need for support by other actors (e.g. policy groups): this raises the question of when and how other actors and other sources of knowledge should be involved in scenario-planning, so as to encourage their buy-in to actions identified by the process. We suggest other CBNRM initiatives may benefit from adapting and applying scenario-planning. However, these initiatives should be carefully monitored since further research is required to understand how and when scenario-planning methods may produce benefits, and their strengths and weaknesses versus other methods
Evolución de los Recursos Hídricos en el “Bajo de Sarmiento” (Patagonia Extra Andina): Impactos Naturales y Antrópico
Water resources dynamics within a basin depend on natural variables (latitude, topography, and climatic variability) and the anthropic uses
of those resources. Social perception on the basin environmental situation and the priority on resources use, define the degree of conservancy of
water resources. Water resources conservancy is critical in the Argentinean Patagonia, where the arid conditions prevail since the early Holocene
until the present. On this work, it is studied the dynamics of the hydrological resources (lakes and rivers) within the “Bajo de Sarmiento”, located in
the center of Argentine’s extra Andean Patagonia. The aim of this work is to understand whether the social perception regarding the priority use of
water resources is leading to management that could increase the impact that naturally affects lakes and rivers in the area by climate variability. Thus,
the hidrogeomorfology dynamics of the “Bajo de Sarmiento”, derived from the combined impact of climate variability and human activity, from the
Holocene to the present, was rebuilt. Geological Sheet 4569-IV Escalante, the SRTM digital terrain model (30m) and Land Sat (5-7-8) satellite images
were analyzed to compare the regime of the main permanent channels described and represented in the literature and historical cartography of “Bajo de
Sarmiento” with their current regimes. The data obtained were compared with fieldwork observations. On the other hand, structured survey was made to
social actors related with water uses in the basin, in order to analyze the social perception on resources. The results showed that while climate variability
(in particular the arid conditions prevailing since the middle Holocene) has historically been the main factor affecting the dynamics of water bodies in
the area, the development of various human activities (based on the perception of the resources that the inhabitants have) have increased these effects
over the past 120 years. Thus the basin has changed from exoreic to endoreic and one of the lakes located within it has been close to disappeared in 2016
Socioeconomic and Environmental Proxies for Comparing Freshwater Ecosystem Service Threats across International Sites: A Diagnostic Approach
In this work, we develop and test proxy-based diagnostic tools for comparing freshwater ecosystem services (FWES) risks across an international array of freshwater ecosystems. FWES threats are increasing rapidly under pressure from population, climate change, pollution, land use change, and other factors. We identified spatially explicit FWES threats estimates (referred to as threat benchmarks) and extracted watershed-specific values for an array of aquatic ecosystems in the Western Hemisphere (Ramsar sites). We compared these benchmark values to values extracted for sites associated with an international FWES threat investigation. The resulting benchmark threats appeared to provide a meaningful context for the diagnostic assessment of study site selection by revealing gaps in coverage of the underlying socio-environmental problem. In an effort to simplify the method, we tested regularly updated environmental and socioeconomic metrics as potential proxies for the benchmark threats using regression analysis. Three category proxies, aggregated from (i) external (global to regional, climate-related), (ii) internal (watershed management-related), and (iii) socioeconomic and governance related proxies produced strong relationships with water supply threat benchmarks, but only weak relationships with biodiversity-related and nutrient regulation benchmark threats. Our results demonstrate the utility of advancing global FWES status and threat benchmarks for organizing coordinated research efforts and prioritizing decisions with regard to international socio-environmental problems
