Legacy of MPW in Rivers

This dataset shows the exposure of global rivers to mismanaged plastic waste (MPW) in 2015 and its projected impact in 2060 based on three scenarios. The different scenarios for 2060 are A: business as usual, B: improved plastic recycling, and C:improved plastic recycling and reduced plastic use projection.

Four global datasets are available that include 1) MPW in 2015 and for three scenarios in 2060, 2) the river type (e.g., meandering or braided, 3) migration of rivers over the past 36-years and 4) the human impact on rivers.

Datasets are described in further detailed in the paper published in Science of the Total Environment, at the Zenodo data repository or using the interactive map available here.

Mismanaged Plastic Waste Dataset Band 'MPW2015' = MPW input in 2015 Band 'MPW2060A' = MPW input in 2060 based on a 'business as usual' projection. Band 'MPW2060B' = MPW input in 2060 based on an 'improved plastic recycling' scenario. Band 'MPW2060C' = MPW input in 2060 based on an 'improved plastic recycling and reduced plastic demand' scenario. Band 'FFPW2015' = Potential plastic accumulation in 2015. Band 'FFPW2060A' = Potential plastic accumulation in 2060 based on a 'business as usual' projection. Band 'FFPW2060B' = Potential plastic accumulation in 2060 based on an 'improved plastic recycling' scenario. Band 'FFPW2060C' = Potential plastic accumulation in 2060 based on an 'improved plastic recycling and reduced plastic demand' scenario.

Values for MPW datasets 1000 = Very High impact (> 10 t/yr/km2) 2000 = High impact (1 to 10 t/yr/km2) 3000 = Moderate Impact (0.1 to 1 t/yr/km2) 4000 = Low Impact (< 0.1 t/yr/km2) 5000 = None

Values for FFPW datasets 1000 = Very High impact (> 100 t/yr/km2) 2000 = High impact (10 to 100 t/yr/km2) 3000 = Moderate Impact (1 to 10 t/yr/km2) 4000 = Low Impact (< 1 t/yr/km2) 5000 = None

River Type Dataset Code 0 = No Data/Background Code 1 = Meandering/Single-threaded River Code 2 = Braided/Multi-threaded River Code 3 = Lacustrine/Wetland Environment

River Migration Dataset Code 0 = No Data/Background Code 20 = Actively migrating river over 36-years of satellite observations Code 30 = Permanent river waterbody over 36-years of satellite observations

River Impact Dataset Code 0 - No Data/Background Code 100 - Free Flowing River Code 200 - Good Connectivity River Code 300 - Impacted River

Copied over the data and created a folder to manage them in a single place

var change = ee.Image('projects/sat-io/open-datasets/MPW/changeMap'); //River Change
var ffr = ee.Image('projects/sat-io/open-datasets/MPW/riverImpact'); //Free flowing rivers
var env = ee.Image('projects/sat-io/open-datasets/MPW/Plastics_Env'); //River Types
var mpw = ee.Image('projects/sat-io/open-datasets/MPW/MPW_data'); // Mismanaged plastic waste

Let me know if you think this okay, I will obviously credit you for curating the data

Here is the dataset page for review, I will be adding this to Table of Contents soon https://gee-community-catalog.org/projects/mpw/

@samapriya cheers looks great!

Awesome closing this issue for now, this will be highlighted in the next release of the catalog. Thank you for contributing
