Klimaatboom

Om de binnenstad tegen hitte en wateroverlast te beschermen zijn er veel meer bomen nodig. Als natuurlijke airco's zorgen ze voor afkoeling door schaduw en verdamping en vangen ze bovendien veel water op. Maar er is één probleem: al die wortels passen nauwelijks in de volle bodem van de binnenstad. In dit onderzoek gingen we daarom op zoek naar een boom zonder wortels.

The golden rules of rewilding

This article aims to supplement the three “golden rules” of rewilding – or three Cs – the Cores, Carnivores, and Corridors – by a fourth C – Compassion, in discussing the case of Oostvaardeplassen in The Netherlands. The cores refer to large, strictly protected ecologically intact areas, carnivores refer to natural predators, and corridors connect passages for fauna movements. We propose a fourth requirement: Compassion. This fourth C would ensure that any active (re)introduction must be in the interests of the individual animals involved. This article briefly explains the history of the Oostvaardeplassen project and leads into a discussion of the scientific (biological requirements of the species, area, and species fit, etc. ) and ethical (animal welfare, ecocentrism, etc.) constraints and opportunities for rewilding. All four Cs, we argue, are absent from Oostvaardeplassen, which can be considered an example of how rewilding should not be undertaken. Against this background, we propose an alternative way forward. https://www.ecos.org.uk/ecos-406-the-golden-rules-of-rewilding-examining-the-case-of-oostvaardersplassen/ LinkedIn: https://www.linkedin.com/in/helenkopnina/

Expectation of Floating Building in Java Indonesia, Case Study in Semarang City

Many delta cities worldwide are dealing with the same kind of problems: rising of the sea level, land subsidence, scarcity of land and illegal housing. Multiple land use is one of these solutions that will help to reduce flooding and scarcity of land. An example of multiple land use is a floating community. This research used Semarang as location for the research into the social acceptance of floating houses. The data in this study were obtained through literature study and survey among inhabitants. The social acceptance of the inhabitants is determined with 35 respondents that have been done in the area of Kemijen, Semarang. In order to determine the social acceptance of floating houses, there are elements used, namely: knowledge of floating houses, perception of risk, urgency, implementation, chose for a floating house, requirements, positive and negative elements, self-sufficient system. According to the result of research, the social acceptance of the inhabitants is quite low, but there is potential because they see positive elements in a floating house. Low social acceptance is caused by the fact that the concept of floating houses is not well known in this community. With raising awareness on the challenges and informing the community on the possibilities on floating infrastructure will result in higher social acceptance.

Air, Money and Space

Airports look alike all over the world. Schiphol has conformed to the patterns of the airport, but its unique design makes it stand out. The book Megastructure Schiphol looks into the history of the Netherlands’ most famous national airport and its sophisticated appearance.Schiphol has grown in fits and starts as a result of ever-expanding traffic in freight and passengers. The area around Schiphol is constantly evolving, yet there is great consistency in the visual aspect of this airport, which can rightly be called a ‘megastructure’. This is not merely due to the efforts of its designers, who have strived to achieve a spectacular simplicity. Other factors, such as its location in a polder and the local planning culture, have also played a role.In Megastructure Schiphol an analysis of its metamorphoses over the past century demonstrates Schiphol’s unique character and its function as a model for other airports.

Characteristics of realigned dikes in coastal Europe

Managed realignment is the landward relocation of flood infrastructure to re-establish tidal exchange on formerly reclaimed land. Managed realignment can be seen as a nature-based flood defence system that combines flood protection by the realigned dike (artificial) and restored saltmarshes (nature-based). So far, research on coastal managed realignment is primarily directed to saltmarsh restoration on formerly reclaimed land. This study focuses on the realigned dikes. The aim of this research is to characterize realigned dikes and to indicate the characteristics that offer opportunities for nature-based flood protection. We categorized 90 European coastal managed realignment projects into two realigned dike groups: (1) Newly built landward dikes and (2) Existing landward dikes of former multiple dike systems. The second group has two subcategories: (2a) Former hinterland dikes and (2b) Realignments within summer polders. For each group we present the realigned dike characteristics of a representative case study. We consider that the use of existing landward dikes or local construction material make realignment more sustainable. From a nature-based flood protection perspective, the presence of an artificial dike is ambiguous. Our results show that targeted and expected saltmarsh restoration at managed realignment does not necessarily result in a greener realigned dike design that suits for combined flood protection with restored saltmarshes. We recommend coastal managers to explicitly take combined flood protection into account in the realigned dike design and steer the topography of the realignment site to facilitate nature-based flood protection and promote surface elevation increase seaward of the realigned dike in response to sea level rise. This makes managed realignment a nature-based flood defence zone for now and for the future.

Vismigratie in Fryslân

Vissen vormen een belangrijk onderdeel van het aquatisch leefsysteem in de vele wateren binnen het beheergebied van Wetterskip Fryslân. Voor het duurzaam in stand houden van de vispopulaties is het van belang dat de vissen vrij baan hebben om te migreren en hun leefgebieden goed bereikbaar zijn om zo hun levenscyclus te kunnen volbrengen. Deze migratiebeweging vindt plaats van zoet naar zout water en vice versa, alsmede binnen zoetwatersystemen onderling. Voorbeelden van migrerende (diadrome) soorten zijn winde (Leuciscus idus), driedoornige stekelbaars (Gasterosteus aculeatus), en spiering (Osmerus eperlanus). Sommige van de migrerende vissoorten steken hele oceanen over in hun migratieproces; voorbeelden hiervan zijn paling (Anguilla anguilla), en zalm (Salmo salar). Door menselijke invloeden ondervinden de migrerende vissen veel hinder op hun migratieroutes. Vele zoetwatergebieden zijn lastig bereikbaar geworden door aanleg van dijken en de plaatsingen van kunstwerken als stuwen, dammen en gemalen in diverse belangrijke routes. Concreet in punten uitgezet zijn de doelen van dit project als volgt: Het verzamelen van essentiële kennis over 30 migratieknelpunten; per locatie een voorkeursoplossing en eventuele alternatieven aandragen (hierbij zal de knelpuntlocatie zelf ruimtelijk ruim worden geïnterpreteerd, bij een gemaal zal bijvoorbeeld ook naar eventuele stuwen in het directe achterland van dat gemaal gekeken worden, alsmede naar de habitatgeschiktheid van dat directe achterland); Prioriteit toewijzen aan de verschillende knelpunten; Eventuele uitvoeringscombinaties onderzoeken en afwegen; Adviseren over vismonitoring najaar 2013 en voorjaar 2014; Aan de hand van deze informatie een verzameling van factsheets opstellen.

Drainage System of Tegalsari Polder for Handling Flood and Tide in Tegal City Indonesia

Although in 2019 the local government of Tegal city Indonesia had constructed a retention basin at drainage system of Siwatu, Tegal Barat, Tegal city with a catchment area of 226 ha, the areas around the system still experienced flood and inundation. This study belonged to a descriptive qualitative research aimed to evaluate the performances of Siwatu drainage system and Tegalsari retention basin. Data of the study included field data and technical data from institutions. Based on the 15-year rainfall data (2014 – 2018) from Pemali - Comal PSDA Office, Central Java Province, Indonesia, the statistical parameters of Cs: 0.0027, Ck: 1.904, Sd: 15.91, Cv: 0.144 were obtained and so Gumbel method distribution was applied in the study, the return period rainfall of 10 years was 138 mm, the flood discharge for Qr.10 years was 9.63 m3/sec., the addition of long storage was 8×2,50×500 m, and the combination of pump addition was of 1 m3/sec. with the long storage of 8×2.00×500 m. By implementing one of the alternative choices, either flood or inundation could be resolved.
