Always Clean and Green

Welcome to today’s post in celebration of World Toilet Day 2022! This post will be delving into Sanergy as a sustainable urban sanitation model across informal settlements in Nairobi, Kenya, East Africa.

Since 2001, World Toilet Day has been celebrated on 19th November as an annual public awareness campaign. Many international actors have used the toilet as a symbol of global sanitation issues to harness support and pushing for ‘the world to ‘give a shit’ about sanitation’ (Thieme and Koszmovszky, 2020: 30). Most importantly, the climate crisis brings huge threats for sanitation systems which poses risk both to public health and the environment. Therefore, it is important to develop sustainable sanitation systems which make productive use of human waste to boost agriculture and improve public health (Zhongming et al. 2020). Here, the ecological toilets provided by Sanergy not only help improve sanitation and the environment but it’s a business opportunity (Thieme, 2018).

‘Turning sh*t into gold’

Sanergy is a social enterprise that was founded by students from the Massachusetts Institute of Technology (MIT). It is a sustainable sanitation model of building ‘over 600 Sanergy toilets’ in ‘six informal settlements in Nairobi’ (O’Keefe et al. 2015: 432), see figure 1. The focus on informal settlements is key as these areas are often faced with inadequate sanitation facilities. Many residents either don’t have toilets in their homes or have to use public shared facilities located far away (Shields and Ruehle, 2016). Sanergy works in three parts; (1) provides sanitation infrastructure thus creating job opportunities, (2) collecting sanitation waste and (3) turning human waste into agricultural fertiliser (Couder and Kibuthu, 2020). Through this, Sanergy creates value for stakeholders at every level due to the constant creation of opportunities and benefits.

Sanergy has largely been successful in delivering sanitation solutions due to three reasons (Couder and Kibuthu, 2020). Firstly, the social enterprise has encouraged more collaborative relationships between local authorities. Sanergy teams work with local governments to consult on issues relating to policy, regulation, land access and waste operating systems. Secondly, Sanergy has built a reputable brand called ‘Fresh Life’ which has promoted grassroots engagement through participatory meetings and educational events. Finally, Sanergy has triggered behavioural change for business development purposes to promote the enterprises goods and services.

Despite the success of this ecological sanitation scheme, water and sanitation issues are inherently gendered and so, the next post will explore these different experiences and implications.

Gendered sanitation

Hello everyone! Today I will be exploring gendered water and sanitation as well as highlighting an exemplar case study from Egypt, North Africa. Femme WASH Traditionally, WASH has been gendered as females have an integral role in engaging with water and sanitation responsibilities, arguably more than men (MacArthur et al. 2020).   These domestic responsibilities include fetching water, cooking, cleaning, caring. However, the implications of these gendered experiences highlight female struggle. The poor WASH conditions make women susceptible to worsened health including back injuries, stunted development of young girls and nutrient deficiencies (Pommells et al. 2018). Furthermore, poor WASH is linked to sexual, psychological, physical and sociocultural violence (Sommer et al. 2014). Unfortunately, these implications occur through inadequate, far away facilities which increases the risk of sexual violence, fights when queuing, domestic violence from husbands and menstruation comp

Water and Sanitation 101

Hi everyone. Welcome to my first post on water and sanitation in Africa. Of course, I am no expert on these matters but join me on my blogging journey 😀 Why the theme? Now, I’ll admit that I chose the theme of water and sanitation before I even experienced one lecture. That being said, I was immediately drawn to this specific thematic area due to my personal experience of different water and sanitation conditions to that of the UK. Although, not specific to Africa, India presents its own challenges within this area which made me want to explore the theme further. Growing up, my childhood holidays would be spent across different Indian states; Karnataka, Andra Pradesh, Gujarat, Maharashtra to name a few. Staying in villages meant that water would be fetched from a shallow groundwater well with a bucket and rope as well as boiling water in the kettle for drinking, cooking and bathing. Experiencing the vastly different water supply systems, makes me appreciate access to safe, treated

Sh*t happens

Welcome back! In this post I aim to provide perspective on the issues relating to faecal contamination and management.   Before we begin, it’s important to understand the reasons for faecal contaminated water across Africa. The basic yet controversial answer would be to blame citizens and development status. However, a more complex answer would question the dishonesty of ‘improved water sources and inadequate provisioning of proper management for faecal waste from the top-down level. Of course, we will be delving into the complex answer.  ‘Improved water sources’ First things first, we have to narrow down a definition of improved water sources. The  WHO/UNICEF Joint Monitoring Programme (2017 ) report defined drinking water as ‘by the nature of their design and construction, have the potential to deliver safe water’ with three conditions: (1) accessible on premises, (2) water should be available when needed and (3) be free from contamination. I’ll admit, even writing the ‘so called’
