Keywords

💡Bellagio Principles for Sustainable Sanitation

The Bellagio Principles for Sustainable Sanitation are guidelines for improving global sanitation systems, particularly in low-income regions. They emphasize sustainability, resource efficiency, and inclusivity in sanitation solutions. In the video, this term is introduced as part of a larger discussion about alternative approaches to conventional sewer systems.

💡Sanitation challenge

The sanitation challenge refers to the global issue of providing safe, accessible, and effective sanitation solutions, particularly in the Global South. The video highlights that despite efforts since the 1970s, over 500 million urban dwellers still lack access to improved sanitation, reflecting the scale of this challenge.

💡Global South

The Global South refers to low- and middle-income countries, often in Africa, Latin America, and parts of Asia, that face significant developmental challenges, including sanitation issues. The video mentions professionals working in the 1970s on addressing sanitation needs specifically in the Global South.

💡SDG target 6.2

SDG target 6.2 is part of the UN Sustainable Development Goals and aims for 'adequate and equitable sanitation for all' by 2030. The video references this goal, questioning why, despite decades of research and effort, much progress is still needed to achieve this target.

💡Improved sanitation

Improved sanitation refers to facilities that hygienically separate human excreta from human contact, such as flush toilets, pit latrines with slabs, and composting toilets. The video contrasts improved sanitation with the lack of such facilities for over 500 million people in urban areas of low- and middle-income countries.

💡Urban growth

Urban growth is the expansion of urban populations and infrastructure. The video states that while access to improved sanitation has increased, rapid urban growth has outpaced this progress, exacerbating the sanitation crisis in many developing cities.

💡Conventional sewer system

A conventional sewer system is the standard method of wastewater management in urban areas, typically involving pipes that transport sewage to treatment facilities.

Transcripts

Did you ever hear about

the Bellagio Principles for Sustainable Sanitation?

And did you know that already in the 1970s there were professionals researching

alternatives to address the sanitation challenge in the Global South?

And yet, in 2021

over 500 million urban dwellers in low and middle-income countries

still do not have access to an improved latrine or toilet.

And almost 2 billion use sanitation services

which are not safely managed.

Although the number

of urban dwellers with access to improved sanitation

increased significantly over the last 50 years,

progress has been outpaced by the rapid urban growth.

Already in the 1970s and 1980s, some visionary professionals

were looking for alternatives to the conventional sewer system.

They argued for an approach not only applying a mix

of different technologies, but also involving other disciplines

such as sociologists, economists and so on...

Now if these ideas already existed 50 years ago, why is it then

that still so much work has to be done to achieve

the SDG target 6.2: Adequate and equitable sanitation for all.

What can we learn from the past?

This publication describes how the international discourse

on urban sanitation has evolved over the last 50 years

and it offers perspectives from two regions

where the lack of urban sanitation provision has been most striking:

South East Asia and Sub-Saharan Africa.

It also provides a detailed description of approaches and tools

developed and tried over the years, and it lists the main challenges

why their uptake at scale has been lacking behind.

The publication also looks forward

and reflects on current trends and emerging developments.

Several emerging approaches

are considering the links between sanitation

and the other sectors, and therefore, have a high potential

to advance urban sanitation in a much more comprehensive manner.

If you want to know how the urban sanitation sector evolved,

if you want to understand where the sector stands today

and what awaits looking ahead...

Then this publication is for you.
