2022-07-06T22:02:17+00:00

With this work, we propose a theoretical review of the relationship between our species and water from an analytical approach that allows us to understand the problem as a result of historical and social processes, that is, as a strictly human aspect. We propose that this relationship is not determined by biological needs, but by the different social and symbolic forms with which our societies are arranged for their existence. The successive and changing crystallization of these processes has produced different types of relationships with water in all its conditions and manifestations, within which we approach the one that makes it a hazard.

Analysis and contextualization of the articulated responses in San Juan de Puerto Rico against the effects of torrential rains (1750-1850)

2022-07-06T22:54:45+00:00

This paper is part of a set of investigations with which we intend to contribute to the study of the circulation of ideas about police science in the Caribbean, in the context of the impact that the incipient globalization process had on the region. In this case we propose the analysis of the effects and the responses given to the problems generated in the urban center of San Juan de Puerto Rico by torrential rains between the years 1750 and 1850, coinciding with the materialization in the city of some significant infrastructures and the implementation of measures related to the improvement of health conditions. For this, we have consulted the “actas capitulares” of the city of San Juan de Puerto Rico and analyzed some of the provisions contemplated on this matter in the good government edicts of the period.

Overflows of the Copiapó River, Chile, and urban floods: 1833-1929

2022-08-03T22:51:54+00:00

Geographical features of the region where Copiapo River is located cause periods of drought and episodes of flooding in the Copiapo Valley. Floods have been recurrent since 17th century, but they did not become disasters until the 19th and 20th centuries. From the perspective of the social construction of disasters, we will analyze some floods that had negative effects on the population –and the responses they generated– in order to understand, through these dynamics, the reasons why occasional floods that occurred in the driest desert in the world became a threat. For this investigation, our main primary sources will be the records on new town held at the Archive, the correspondence between the local and central administrations, the minutes of the municipal council and the local press

Rains and Floods in the Desert: Risk Perception, Political Discussion and Economic Proposals in the Province of Tarapacá (Perú), through the Written Press (1829–1875)

2022-07-07T00:07:49+00:00

Although the province of Tarapacá is located in the driest desert on the planet, the Atacama Desert, it is occasionally affected by floods between December and March due to summer rains from Bolivia. This phenomenon, which is locally called the “Bolivian winter”, has become part of the imagery of the inhabitants of Tarapacá. It has also become part of the political discussions and economic proposals to mitigate the damage caused when its intensity increases and recover the surplus water for agriculture and human consumption. This paper takes a closer look at these discussions in the Written Press during a particularly complex and interesting period, namely the second half of the 19th century, with the formation of the Republic of Peru, the expansion of the saltpeter industry and the transfer of this territory to the Chilean sovereignty.

“In Deep Waters”: a history of lost battles against water and disastrous floods in Colombia, 1950-2011

2022-08-03T22:55:56+00:00

Since the mid-19th century, vast areas of wetlands in the Andes and Colombian Caribbean regions have been a propitious field to develop desiccation, drainage, and canalization projects for agriculture and urban expansion. This paper synthesizes the sum of factors representing a fight against water, which broke ancient harmonic practices of coexistence with rivers and wetlands. That campaign failed from its start due to the omission of hydric and ecosystem dynamics. This article takes representative junctures, recorded in newspapers, to explain how water's improper management has been one of the leading causes of repetitive and disastrous floods during the 20th and 21st centuries in Sabana de Bogota, the Cauca valley, and the Caribbean plains.

Tributaries and urban regulations in the construction of the threat in Colima, Mexico (1970-2022)

2022-08-20T17:45:57+00:00

Colima is a city in western Mexico, founded by Spanish people in the sixteenth century, between the Colima River and the El Manrique stream. Throughout its history, the relationship of the city with these two bodies of water was beneficial, but since the last decade of the twentieth century its inhabitants have suffered impacts from flooding and siltation. This work aims to expose the effects of this relationship, identify the causes and make proposals, through an urban study, with an interdisciplinary approach. The main findings show determining factors such as the presence of abundant rainfall, the invasion of the channels, the lack of infrastructure, the change of materials in the road structure and the deficient application of urban regulations. Together, these variables have led to the water of the tributaries, previously beneficial, in the twenty–first century representing a threat to certain areas of the city.

Tropical cyclones that hit Venezuela and Mexico (20th Century)

2022-07-06T22:39:47+00:00

This work aims to draw attention to the relevance of comparative methodologies for the study of phenomena with a long territorial scope, whose affectation produces adversities in geographically distant and contextually different countries. To this end, we have relied on the case of hurricanes, whose displacement over the Gulf–Caribbean region can affect countries as far apart as Venezuela and Mexico. The documented reconstruction of disastrous events in this regard, makes it possible to demonstrate the characteristics of the problem, as well as the need to develop this type of methodology, essentially based on historical research.

Droughts in Santiago de Chile during the eighteenth century

2022-07-10T22:51:19+00:00

The research analyzes the various practices, confrontations –and the respective punishments by the authorities– that arose in periods of drought and water scarcity in Santiago de Chile during the eighteenth century. The measures taken by the neighbors and by the institutions were reconstructed and compared. For this, we focus mainly on the minutes of the council, official communications located in the collections of the Captaincy General and Royal Audience (National Historical Archive, Chile), as well as in the General Archive of the Indies. The results show that the neighbors continuously transgressed the rules on the distribution of water not only in times of climatic extremism, for which it became a daily practice that allowed to notice a structural conflict related to the management and control of the natural resource, especially disputed by social actors with economic interests.

Water scarcity in Mendoza (Argentina): a socio–historical look from the second half of the 19th century

2022-08-20T17:04:17+00:00

This research analyzes the processes of water scarcity that impacted the territories of the province of Mendoza (Argentina) from the second half of the nineteenth century until the end of the twentieth. From a historical–environmental perspective, we explores will analyze these hydroclimatic situations from the perspective of various social actors of the provincial territory based on the data obtained from documentary sources.

Systematic literature review on toxicants impacts dormant eggs in temporary wetlands: an ocean of unknowingness.

2022-02-23T15:49:37+00:00

Temporary wetlands are recognised biodiversity hotspots. Dormant egg banks, as part of their cryptic biodiversity, are responsible of wetlands resilience. Egg banks are also known to be sensitive indicators of anthropogenic disturbances. This study aims to assess the current state of research of toxicants impact on dormant egg banks in temporary wetlands. The systematic literature review carried out has shown the small number of studies on this topic. This study provides evidence of commonality concerning negative impact effect on the organisms, reducing hatching success, dormant eggs production and emergence, or species richness, among others, which might weaken ecosystem stabilization mechanisms by reducing biodiversity. Our review also revealed a glaring lack of in situ and long-term studies for understanding ecosystem consequences of toxicants on temporary wetlands. These gaps in knowledge hamper our ability to design and implement evidence-based conservation and management programs but opens opportunities for new research lines.

Public-Private Partnerships in water & sanitation services. A case study in Veracruz, Mexico

2022-02-22T11:36:04+00:00

In the conurbation of the port of Veracruz, Mexico, the water and sanitation system is governed by a public-private partnership scheme arising from legal and organizational arrangements that benefit economic groups and government sectors. Consequently, the responsible company offers the population an inefficient service and is negligent in the face of the social and environmental damage it causes. Users and political figures demand to cancel the concession; however, the authorities have ignored the demand. In order to find alternative solutions to the problem, a qualitative-quantitative examination of a wide documentary collection, which included text mining, networks of actors and multivariate analysis, allowed to determine the contextual and characteristic aspects of the system. The results suggest the need to reform water and sanitation management in the conurbation; privilege public welfare; and promote mechanisms of transparency, citizen participation and co-responsibility.

Identification of potential effects of tourist facilities on drainages in the Cuale-Pitillal river basin (coastal zone of Puerto Vallarta, Mexico)

2022-02-18T17:20:22+00:00

This work aims to identify potential effects on natural drainage, taking as an example the mouth of the Cuale-Pitillal river basin in Puerto Vallarta, Mexico.

For this, the overlap of tourist works on the sections of natural currents was made using a Geographic Information System (GIS), a Digital Elevation Model and the review of publications of the anthropogenic interaction with watersheds.

Due to the interruption of natural drains, there has been a change in the spatial and landscape configuration of the basin, in addition, it is inferred that the study area may be causing negative effects related to waste water discharges and sedimentary deficit.

The spatial identification of these effects, can contribute to coastal planning to locate critical points of affectation to the functional integrity of the basin and potential risk areas to the population in the event of hurricanes or storms.

The transboundary waters of the La Plata Basin (South America) from the perspective of the 2030 Agenda

2022-02-18T16:58:15+00:00

This article presents the main challenges for the prospective shared management of transboundary water resources, having as central analysis the 2030 Agenda and the Sustainable Development Goals (SDGs), especially SDG-6 on water and sanitation. To this end, it considers the La Plata Basin, the fifth largest transboundary basin in the world, shared by Argentina, Brazil, Bolivia, Paraguay and Uruguay, and the Intergovernmental Coordinating Committee of the La Plata Basin Countries (CIC) as a case study. The analysis is based on literature review methodologies and desk studies and focuses on the interactions of the CIC's Strategic Action Plan (SAP) with SDG-6 and its indicators. The article enumerates the relevant aspects of this milestone of this international agenda framework with the construction of tools and initiatives that facilitate the management of the transboundary waters of the La Plata Basin by the SAP.

Tools for drought monitoring and control: a meta-analysis in context

2022-08-03T22:14:58+00:00

The research consisted of performing a meta-analysis of drought monitoring and control tools in all their manifestations, which identified the existence of little consolidated data on hydraulic as a weakness. A total of 3,116 articles published in the period 2000-2020 were analyzed, identifying drought management as the most published topic. Other metrics were worked on, referring to the total number of articles and their distribution by year and country, the distribution by topics and by most cited journals, articles and authors. A total of 46 indices were found to be among the most widely used for drought monitoring and control at the global level, with those applied to meteorological drought standing out among them. No reference was found of indices applied to the management of hydraulic drought, which constitutes a challenge for researchers and managers of water resources.
