Op 22 april is het Earth Day, een dag waarop sinds 1970 wereldwijd aandacht wordt gevraagd voor milieubescherming en duurzaamheid. Een belangrijk thema, want de aarde staat onder druk door klimaatverandering en andere milieuproblemen. In Nederland zijn er verschillende initiatieven vanuit de overheid, het bedrijfsleven en ook burgers om te verduurzamen. Maar hoe belangrijk vinden kiezers het eigenlijk dat Nederland duurzamer en klimaatneutraal wordt? En wie is daar volgens hen voor verantwoordelijk en waar lopen ze tegenaan bij het (verder) verduurzamen van hun eigen leven? In deze blogpost bespreken we de resultaten van een recent en landelijk representatief onderzoek onder ruim 2.500 consumenten naar de opvattingen van Nederlandse kiezers over duurzaamheid. De resultaten van dit onderzoek zijn samengevat in een interactief, online dashboard: https://goldman.eco/de-relatie-tussen-de-politieke-voorkeur-van-nederlanders-en-duurzaam-leven-lessen-voor-earth-day/

The Tuntang Watershed is an important watershed in Central Java. Management of watersheds in the Tuntang stream is a priority for various parties to carry out. One of the things that threatens the sustainability of the Tuntang watershed is erosion. The erosion rate can lead to sediment accumulation and siltation in the Tuntang River reservoir, which can cause catastrophic flooding. Flood disaster mitigation caused by erosion needs to be done, one of which is by calculating the erosion rate per year that occurs in the Tuntang watershed. This study calcultated the predicted erosion rate (per year in the Tuntang watershed) using the Revised Universal Soil Loss Equation (RUSLE) method, processed using the Google Earth Engine (GEE). Google offers a cloud-storage technology called GEE. Programming in JavaScript is required to operate GEE. GEE is a petabyte-scale data-based tool that can be used to analyze and archive geospatial data that is open source. The computing environment is designed for the processing of geospatial data, including the depiction of spatial analysis of satellite imagery. Data for RUSLE is obtained from the database in GEE, and the results can be imaged on a map. According to the study's findings, the degree of soil erosion throughout the Tuntang Watershed was essentially constant, with Moderate erosion predominating in the majority of locations. Senjoyo Sub Watershed, Rowopening Sub Watershed, and Tuntang Hilir Sub Watershed are the primary locations with severe erosion. Rowopening Sub Watershed is the region that is the worst.

For interspecies justice, animal welfare, and animal rights, the planet needs to be divided on the basis of species' natural resource requirements. The Half-Earth View is that to maintain viable populations of the Earth's remaining species, half of landscapes and seascapes need protection from intensive economic activity. This protection is needed outside the nature preserve system, such as in agricultural areas or cities, so nature can co-exist with local communities.

In the past, textile material was used to add value to buildings in various applications, as well as improving building performance in terms or in terms of building and acoustics properties, and increasing the esthetic value.Textiles are light in weight, easy to shape, strong, insulating, moisture-regulating and can be provided with extra functions. Particularly in areas with an earthquake risk, as well as cases with a temporary demand for flexible shelters, textiles and primary use.
Single-Use Plastics (SUPs) are at the centre of European Union Agenda aiming at reducing the plastic soup with the EU Directive 2019/904. SUPs reduction is pivotal also in the Dutch Government Agenda for the transition to a Circular Economy by 2050. Worldwide the data on SUPs use and disposal are impressive: humans use around 1.2 million plastic bottles per minute; approximately 91% of plastic is not recycled (www.earthday.org/fact-sheet-single-use-plastics/). While centralised processes of waste collection, disposal, and recycling strive to cope with such intense use of SUPs, the opportunities and constraints of establishing a networked grid of facilities enacting processes of SUPs collection and recycling with the active involvement of local community has remained unexplored. The hospitality sector is characterised by a widespread capillary network of small hospitality firms nested in neighbourhoods and rural communities. Our research group works with small hospitality firms, different stakeholders, and other research groups to prompt the transition of the hospitality sector towards a Circular Economy embracing not only the environmental and economic dimensions but also the social dimension. Hence, this project explores the knowledge and network needed to build an innovative pilot allowing to close the plastic loop within a hospitality facility by combining a 3D printing process with social inclusiveness. This will mean generating key technical and legal knowledge as well as a network of strategic experts and stakeholders to be involved in an innovative pilot setting a 3D printing process in a hospitality facility and establishing an active involvement of the local community. Such active involvement of the local inhabitants will be explored as SUPs collectors and end-users of upcycled plastics items realised with the 3D printer, as well as through opportunities of vocational training and job opportunities for citizens distant from the job market.
The pipelines are buried structures. They move together with the soil during a seismic event. They are affected from ground motions. The project aims to find out the possible effects of Groningen earthquakes on pipelines of Loppersum and Slochteren.This project is devised for conducting an initial probe on the available data to see the possible actions that can be taken, initially on these two pilot villages, Loppersum and Slochteren, for detecting the potential relationship between the past damages and the seismic activity.Lifeline infrastructure, such as water mains and sewerage systems, covering our urbanised areas like a network, are most of the times, sensitive to seismic actions. This sensitivity can be in the form of extended damage during seismic events, or other collateral damages, such as what happened in Christchurch Earthquakes in 2011 in New Zealand when the sewerage system of the city was filled in with tonnes of sand due to liquefaction.Regular damage detection is one of key solutions for operational purposes. The earthquake mitigation, however, needs large scale risk studies with expected spatial distribution of damages for varying seismic hazard levels.
