Dear Joseph,

Just a little addition:
You are probably aware that the theme for the next United Nations Environment Assembly (UNEA) is: "Delivering on the environmental dimension of the Sustainable Development Agenda 2030". A highlight at the core of the session ministers will discuss how to achieve a 'Healthy Environment for Healthy People'. There is a strong linkage between your today concern and the theme of the next UNEA2. I would like to engage you and your group in participating to the e-discussion which will be organized as we are moving towards the UNEA2. I therefore look forward to seeing you playing an important role during e-discussion.
Please visit: and also have your say!

3. Land tenure issues health and sanitation are major problems in slums. How can legislation and policies help in solving these issues?
Mokaya Eric (from Kenya)
Dear Eric,
Providing water and sanitation services to the urban poor often takes place in contexts with complex formal and informal land ownership arrangements. Firstly, the people in most need of improved water and sanitation are often tenants, and this raises diverse challenges: for example, landlords may be unwilling to invest in better toilets. Secondly, improving water and sanitation services often requires land for construction of communal or public facilities, and land tenure again raises diverse problems here.
This Topic which we are discussing demonstrate how the dynamics of tenure and tenancy underpin the incentives and priorities of the major stakeholders in improving basic services. The poor living conditions of low-income settlements with high tenancy rates are a result of a lack of investment by all parties. Lack of adequate space for basic services is a result of informal urban development that exceeds the capacity of town planning. Tenure and tenancy dynamics can be complex and strongly rooted in political and historical underpinnings. Understanding how these dynamics influence different programme options is key to developing appropriate basic services for the urban poor.
While also answering to we found this very interesting publication which I recommend you.
This is also an example of multi-stakeholder approach for problem solving and sharing ideas and experiences are key.
I would encourage you and your colleagues to continue engaging in such experience sharing and information exchange, using whereas it possible.
Finally, Eric, I would also wish to refer you to the work of my colleagues from the
International Environmental Technology Centre (IETC) on water and Sanitation.
Hope it helps,

2. How can public private partnership assist in slums upgrading of slums upgrading and what other strategies can the government put in place in place to help upgrade slums? In terms of infrastructure and housing
joseph mugo (from Kenya)
Dear Joseph,
Slums are the spontaneous response of the poor to their own needs for shelter in cities. They are essentially a private phenomenon, which responds to market incentives and distortions without extensive government interference. Slums form part of the informal economy, and they house many of the informal economy’s actors. Slums thrive and grow because a significant amount of economic activity contributes to the provision of basic shelter, water, food, energy, and other goods to slum dwellers. Slum dwellers are often entrepreneurs themselves, but their demand also attracts other informal entrepreneurs.
The formal private sector has played a role in slum creation as well as the role of injured party, defendant of property rights, or passive landlord. Private landowners may even be complicit with the “land invasions” and “informal land developers” that establish slums on their property because it opens the opportunity to charge rent to inhabitants while legally reserving the right to evict squatters when better opportunities for commercial development arise
I would also like to invite you to visit an excellent resource portal which my colleagues from the Ecosystem management and land degradation have created. I am sure that you will find a very useful tool to continue the research which you and your team are working on. Please visit:

1. What are the major factors that contribute to growth of slums in urban areas and how can they be controlled
joseph mugo (from Kenya)
Dear Joseph,
This is a excellent question and of course of concern to you and your network. is a place where discussion on Environmental Health issue should also take place.
While forwarding this specific question to a more large expert network, I will also count on your colleagues at the University of Nairobi to share their thoughts on this issue of concern.
