Abstract

A city resilient to climate change is characterized by effectively responding to and recovering from the negative impacts of climate hazards. In the city of Santiago, Chile, extreme weather that can be associated with a nascent manifestation of climate change has caused high-turbidity events, repeatedly forcing the main water company to interrupt the supply of drinking water, affecting millions of people. This study proposes a transformative response to reduce harm from extreme events due to climate change.

Abstract

Sustainable Development Goal 14 of the United Nations aims to “conserve and sustainably use the oceans, seas and marine resources for sustainable development”. Achieving this goal will require rebuilding the marine life-support systems that deliver the many benefits that society receives from a healthy ocean.

Abstract

Since the impacts of climate change will be felt most directly through changes in water availability and water security, adequate tools are required to support water resources management decisions for the medium and long term. The Climate Risk Informed Decision Analysis (CRIDA) provides a pathway for more localized vulnerability assessments of water resources under climate change, while encompassing the uncertainty of current global climate projections.

Abstract

The United Nations (UN) Framework Convention on Climate Change (UNFCCC) was adopted in 1992 and governments have participated since then in its decision-making body, the ‘Conference of the Parties' (COP). Chile presided over the 25th annual COP held December 2019 in Madrid, Spain. While COPs necessarily emphasise energy negotiations and carbon mitigation policies, water is an increasingly prominent topic because of the need for water in energy production and its importance in nature-based and engineered adaptation and mitigation solutions. Climate-change-induced water impacts are key considerations in, for example, infrastructure planning under changing flood and drought risk, changing agricultural practices and hydropower. Already ninety percent of all-natural disasters are water related.

Abstract

Droughts can have serious negative impacts on the water quality needed for irrigated agriculture. The Metropolitan region of Chile is a relevant producer of high-value crops and is prone to droughts. Standardized Drought Indices were used to characterize meteorological and hydrological droughts for the period from 1985 to 2015.

Sobre el libro

This book offers an authoritative analysis of the challenges that have arisen as a result of modern technologies. It covers several environmental problems, such as climate change, overexploitation of natural resources, loss of natural habitats, pollution and human population growth, and discusses practical scenarios for sustainable human dwelling of our planet. Adopting an interdisciplinary approach, the first part introduces “global changes”, describing how they are happening in reality, and the challenges arising from them. The second part introduces methodological approaches borrowed from various disciplines, such as engineering, management science, philosophy and theology, which can help deal with the contemporary challenges resulting from global changes.

Modeling present and future ice covers in two Antarctic lakes

Abstract

Antarctic lakes with perennial ice covers provide the opportunity to investigate in-lake processes without direct atmospheric interaction, and to study their ice-cover sensitivity to climate conditions. In this study, a numerical model – driven by radiative, atmospheric and turbulent heat fluxes from the water body beneath the ice cover – was implemented to investigate the impact of climate change on the ice covers from two Antarctic lakes: west lobe of Lake Bonney (WLB) and Crooked Lake.

Abstract

Mediterranean Chile is part of the five recognized mediterranean‐type climates in the world and harbours a very rich floral diversity. Climate change has been reported as a significant threat to its biodiversity. We used the flora of Mediterranean Chile to analyse how biodiversity patterns, as measured by phylogenetic diversity, genus and species richness will respond to climate change scenarios and identify the areas that will harbour the greatest evolutionary potential and biodiversity richness. We also evaluated how these spatial patterns are depicted within the current network of protected areas.

Abstract

This article identifies and analyzes some of the main knowledge gaps that affect the development of climate adaptation policies in the Latin American context. It is based on a comparative analysis of online survey results conducted among government officials working on climate adaptation in six countries of the region: Argentina, Brazil, Chile, Costa Rica, Paraguay and Uruguay.

Abstract

The identification of research questions with high relevance for biodiversity conservation is an important step towards designing more effective policies and management actions, and to better allocate funding among alternative conservation options. However, the identification of priority questions may be influenced by regional differences in biodiversity threats and social contexts, and to variations in the perceptions and interests of different stakeholders. Here we describe the results of a prioritization exercise involving six types of stakeholders from the Mediterranean biome, which includes several biodiversity hotspots spread across five regions of the planet (Europe, Africa, North and South America, and Australia).
