Research

Vegetation Green areas Vegetation types, forests, parks, protected areas, open spaces, agriculture mosaic

Vegetation layers Farmland

▪ Vegetation type including farmland forest, nature reserve (major part of vegetation) are majorly located on peripheral boundaries of Duisburg.

▪ Whereas Grass, Meadow, are located around Rhein and Ruhr river.

Forest

The landscape park Duisburg-Nord (leisure park )

Grass

▪ Built - 1990s ▪ On a former ironworks industrial area.

Nature reserve

▪ Before the end of 19 century – Forest area of the Krupp company ▪ At the end of the 19th century – Silting out the slag produced in the steel industry .

▪ In 1919 – Recreation area (Sportpark Duisburg) https://de.wikipedia.org/wiki/Sportpark_Du isburg

Comparative Analysis Topography Vegetation Urban Infrastructure

MAP 1: Landscape dynamics analysis (latest map) Topography+Water body+Vegetation base(vegetation loss area)+Agricultural mosaic+Infrastructure Maybe deciduous trees inhabit in the gap area Flood risk area and Vegetation loss area , Is not overlapping In the summer.

However, in winter It’s overlapping Deciduous trees area are vulnerable to flood risk

MAP 1: Landscape dynamics analysis (latest map) Topography+Water body+Vegetation base(vegetation loss area)+Agricultural mosaic+Infrastructure

Rail road is overlapping with Vegetation loss in summer

Main road is overlapping with Vegetation loss in winter

Rapidly developed industrial area is overlapping with vegetation loss area below the river

Conclusion – ▪ Loss of vegetation in recent years.

▪ Overall Reduction of density of vegetation in recent years.

▪ Major reduction of density in Farmland layer.

SWOT Analysis and Guideline: SWOT Map

Guideline: - Introduction - Main Focus - Suggestions Map

SWOT Analysis Map

S Very stable topography.

Habitat patch connectivity.

9% largest catchment in Urban area.

79.4% in cropland More green spaces on peripheral boundaries of Duisburg.

W

O

T

Low water levels lead to transportation disruptions that cause a significant and economically meaningful decrease of industrial production. (Ademmer, Ed, 2020)

Create more green spaces in city center

Flooding in winter, as water can not seep into the frozen ground

Create more green spaces in city center

One of the 14 large cities in the lower rhine

Railways connected to the other major cities in Germany.

Loss of habitat

Ecological connectivity needs improvement Loss of aluvial flood planes, causes issues.

Less vegetation in city center.

Sustainable development - The landscape park Duisburg-Nord conversion of brown field (former industrial areas into leisure park).

City has parking for the residents car.

The highways are connected well to the other big cities in the vicinity of the Duisburg.

The city has cycling paths which are beneficial for the inner city traveling.

Increased urbanization.

The traffic conjunctions is a problem during traffic jam times for local people.

Most of the people use their own cars instead of the public transportation.

Thus, people can use it during weekends and holidays to travel to other cities.

River side can be a sidewalk and cycling paths for the residents.

Flooding and other climate change issues City has less parking parking spaces for people during weekends and weekdays, when all local people and tourists are in the street.

The city has many bus and train stations but it is needed to have public transportation like bus stations in the border of the city.

DUISBURG GUIDELINES

INTRODUCTION

Duisburg is the only city of the Rhine-Ruhr region lying on both the Rhine and Ruhr rivers.The city spreads along both sides of these rivers.

The main issues we found are the vegetation loss, flood risks and traffic orientated urban area.

Therefore, we are aiming to enhance the ecological environment based solutions on our researches.

MAIN FOCUS Improve ecological environment

Replacement of car lane with public transportation

Creating a water catchment area
