Title A name given to the resource Crisis del agua, turismo y variabilidad climática en la isla de San Andrés Creator An entity primarily responsible for making the resource Tomás Guerrero Jiménez Description An account of the resource Por medio de los Decretos 0170 del 15 de abril de 2016 y 0340 del 16 de agosto de 2017, la Gobernación departamental declaró el inicio y el final de la calamidad pública por desabastecimiento hídrico en la isla de San Andrés (Colombia), que tuvo una duración de 15 meses. La reducida oferta hídrica de 2016 llevó a manifestaciones sociales en contra de la administración departamental, generó conflictos entre el sector turístico y la población residente por el acceso oportuno al agua y dejó en el imaginario colectivo institucional como culpable de la situación presentada al fenómeno climatológico ENOS (El Niño oscilación del sur) de ese año, que trajo consigo una disminución importante en las precipitaciones y, con ello, en la oferta de agua potable. En este artículo se exploran factores adicionales que contribuyeron a la disminución de la oferta de agua en la isla, como el incipiente control de fugas en redes de distribución del acueducto, la falta de planificación demográfica para un turismo de sol y playa creciente, y una prospectiva territorial discordante con el cambio climático esperado en atención a la disminución de lluvias (y, por ende, la oferta de agua subterránea), principal fuente de abastecimiento hídrico en San Andrés. Adicionalmente, el artículo presenta un análisis –para 10 años previos a la crisis hídrica– de oferta de agua bajo escenarios de variabilidad climática, después de pérdidas técnicas y operacionales en los sistemas de acueducto, con respecto a la demanda de agua de turistas y residentes de esos mismos años y proyección a 2040. Se encuentra que, de seguir los patrones actuales de explotación de acuíferos y manejo de la oferta disponible, se tendrían los mismos problemas hídricos en el primer semestre de cada año, independientemente de un evento climatológico.

Title A name given to the resource The Indian Ocean - The Challenges beyond the Plastic Pollution Creator An entity primarily responsible for making the resource Amrita Dhillon, Abhinav Kaushal Description An account of the resource El calentamiento del Océano Índico resulta ser el mayor contribuyente en línea con la tendencia general de la temperatura media mundial de la superficie del mar, al tiempo que evidencia  signos de sobrepesca, que parecen estar aumentando. Se han vertido en él alrededor de 5-6 millones de toneladas de petróleo -alrededor del 40% del derrame total de petróleo en las aguas del mundo-, mientras que las presiones humanas (población, infraestructura urbana, etc.) ponen en peligro cada vez más los ecosistemas marinos subyacentes, que sustentan la pesca de la región y otras amenazas incluyen un aumento acelerado del nivel del mar en él, que representa una amenaza inminente para los estados costeros. Teniendo en cuenta lo mencionado, esta nota aborda el tema de la región del Océano Índico / IOR, una de las ubicaciones estratégicas relacionadas con la paz, la seguridad y el comercio, desde la perspectiva de su papel con respecto al cambio climático y las acciones y reacciones de los países a su alrededor. Se concluye que la contaminación marina es un problema grave, que causa el deterioro de los recursos en el Océano Índico y aunque los países de la zona invierten una gran cantidad de dinero para combatirlo, ello no resuelve la falta de conciencia entre las masas. Los esfuerzos de las organizaciones regionales, aunque son notables, parecen superficiales y carecen de un impacto significativo, mientras que también se observa la necesidad de innovación en los métodos de implementación para reducir / reciclar los desechos, minimizar los derrames de petróleo y monitorear la vida acuática.

Title A name given to the resource Desafíos del cambio climático en Tabasco, México / Challenges of climate change in Tabasco, Mexico Creator An entity primarily responsible for making the resource Sofía Ruiz Liévano Description An account of the resource The State of Tabasco is vulnerable to the floods caused by Climate Change directly related to human intervention. The objective of this paper is to reflect how Climate Change is regulated by law in Tabasco. First: We review doctrinal concepts inherent in the topic: vulnerability, resilience, mitigation and adaptation; then systematically, we carry out a normative analysis of the legal framework of climate change that includes the development plan and public policies in this area. Results: Tabasco's municipal development plans do not contemplate clear, concrete or forceful actions for the proper management of this problem; mitigation, adaptation strategies including the risk atlas are null or vague. Conclusion: Tabasco has a vast legal order of climate change, however there are serious shortcomings in its implementation; therefore in Tabasco the right to a healthy environment is not guaranteed, because it violates the Constitution based on the principles of Human Rights.

En este trabajo se presentan evidencias de actividad humana y cambio climático en la región tropical de la sierra de Los Tuxtlas, con base en el registro de indicadores de cambio ambiental para los últimos 2000 años. En la secuencia lacustre del Lago Verde, localizado en la porción norte del Golfo de México, se llevó a cabo el análisis de susceptibilidad magnética, carbón orgánico total, contenido de polen, diatomeas y partículas de carbón con el propósito de documentar el impacto humano y su efecto en el ambiente, así como, identificar las condiciones climáticas en la que se desarrollaron. Se identificaron dos etapas de actividad en la cuenca, la primera durante el Clásico en condiciones climáticas secas con una deforestación intensa, actividad agrícola, fuegos, eventos de erosión y niveles lacustres bajos. La segunda etapa a partir de 1960 se caracteriza por deforestación, actividad agrícola y en el lago hay niveles altos y condiciones eutróficas pero se desarrolla bajo escenarios climáticos diferentes.

Title A name given to the resource Biomasa residual vegetal: tecnologías de transformación y estado actual Creator An entity primarily responsible for making the resource Pedro Elías Patiño Martínez Description An account of the resource La biomasa residual vegetal es una alternativa para la producción de energía a nivel mundial. La conversión de los residuos vegetales en alguna forma energética requiere la aplicación de tecnologías que estén acorde a lo expresado en el numeral IV, artículo 2 del Protocolo de Kyoto de la convención marco de las Naciones Unidas sobre cambio climático (1998) y normativas específicas de cada país o región. Las tecnologías que se le pueden aplicar a los residuos vegetales son bien conocidas a nivel mundial, dentro de estas se incluye: la combustión que permite generar un combustible denominado bio-oil, la gasificación que genera principalmente dióxido de carbono y amoniaco, la pirolisis que genera un gas combustible, y procesos biológicos (fermentación y digestión) que generan bioetanol y biogás. Actualmente en España, Estados Unidos, Brasil y Alemania, entre otros, se vienen desarrollando políticas con el fin de incentivar la implementación de plantas de biomasa. En Colombia la transformación de la biomasa residual vegetal hasta ahora se encuentra en fase de experimentación en laboratorios de Investigación científica principalmente en instituciones de educación superior.

Spisla, M. Sswat, M. Zavala Moreira Description An account of the resource Eastern boundary upwelling systems (EBUS) are among the most productive marine ecosystems on Earth. The production of organic material is fueled by upwelling of nutrient-rich deep waters and high incident light at the sea surface. However, biotic and abiotic factors can modify surface production and related biogeochemical processes. Determining these factors is important because EBUS are considered hotspots of climate change, and reliable predictions of their future functioning requires understanding of the mechanisms driving the biogeochemical cycles therein. In this field experiment, we used in situ mesocosms as tools to improve our mechanistic understanding of processes controlling organic matter cycling in the coastal Peruvian upwelling system. Eight mesocosms, each with a volume of ∼55&thinsp;m3, were deployed for 50&thinsp;d&thinsp;∼6&thinsp;km off Callao (12∘&thinsp;S) during austral summer 2017, coinciding with a coastal El Niño phase. After mesocosm deployment, we collected subsurface waters at two different locations in the regional oxygen minimum zone (OMZ) and injected these into four mesocosms (mixing ratio ≈1.5&thinsp;:&thinsp;1 mesocosm: OMZ water). The focus of this paper is on temporal developments of organic matter production, export, and stoichiometry in the individual mesocosms. The mesocosm phytoplankton communities were initially dominated by diatoms but shifted towards a pronounced dominance of the mixotrophic dinoflagellate (Akashiwo sanguinea) when inorganic nitrogen was exhausted in surface layers. The community shift coincided with a short-term increase in production during the A. sanguinea bloom, which left a pronounced imprint on organic matter C&thinsp;:&thinsp;N&thinsp;:&thinsp;P stoichiometry. However, C, N, and P export fluxes did not increase because A. sanguinea persisted in the water column and did not sink out during the experiment. Accordingly, export fluxes during the study were decoupled from surface production and sustained by the remaining plankton community. Overall, biogeochemical pools and fluxes were surprisingly constant for most of the experiment. We explain this constancy by light limitation through self-shading by phytoplankton and by inorganic nitrogen limitation which constrained phytoplankton growth. Thus, gain and loss processes remained balanced and there were few opportunities for blooms, which represents an event where the system becomes unbalanced. Overall, our mesocosm study revealed some key links between ecological and biogeochemical processes for one of the most economically important regions in the oceans.
