Identifying Constraints to Increasing Sanitation Coverage

2008 | The world bank, Water and Sanitation Program

This field note summarizes research from two studies undertaken in rural and peri-urban areas of Cambodia; one on the demand forlatrines among consumers, and the other on the supply of latrines by the private sector. It provides discussion on the opportunity toincrease latrine purchase and installation via market forces, andoutlines the recommended interventions on both the demand andsupply dimensions of the market to achieve this. There is a strong demand for latrines among the Cambodian population, yet this demand remains mostly unrealized. While there is a functioning market for latrines, it is constrained by a strong preference for unaffordable top-end designs on the consumer side, and a limited ability to supply lower cost or upgradable latrines on the supply side. These weaknesses can be addressed. It has been demonstratedthrough Community Led Total Sanitation (CLTS) efforts that the high-end design preference can be overcome and consumers will construct cheaper latrines if adequately motivated to do so. The supply side needs to be strengthened to provide for the cheapest and mid-range end of the market. The components ofcheaper designs are available. However, cheaper design options are not ‘packaged’ in a way that is obvious or easily accessible to consumers, nor with clear pricing information, nor in a way that maps out an upgrade path starting with a lower cost initialinvestment. Developing market strategies that supply the required packaged information, products and services and that equally focus on demand creation to persuade consumers to consider alternate and more affordable options, may help turn stated demand into an actual acquisition and contribute to increased sanitation coverage in the country.

Economic Impacts of Sanitation in Cambodia Summary

2008 | The world bank, Water and Sanitation Program

In 2004, only about 17\% of Cambodian people had access to improved sanitation, meaning that there were still more than 11 million Cambodians living with an unimproved latrine or with no latrine at all. Although the figure given by the Cambodia Demographic and Health Survey (CDHS) in 2005 indicates the increase of access coverage to nearly 22\% in 2005, it is estimated that about 204,000 people need to gain access to improved latrines each year if Cambodia is to achieve the internationally-set Millennium Development Goal target of reducing by half in 2015 the proportion of people without improved sanitation from the base year of 1990. While there is a consensus that lack of access to clean water and improved sanitation has a variety of impacts, there is often a lack of evidence to affirm that poor sanitation imposes a significant burden on society. In response, the “Sanitation Impact” study, initiated by the World Bank Water and Sanitation Program, aims to generate sound evidence on the negative impacts of existing sanitation and hygiene conditions and the potential benefits of improvementsin sanitation and hygiene in Cambodia.

Optimising water and phosphorus management in the urban environmental sanitation system of Hanoi, Vietnam

2007 | Elsevier

Many areas in the world face clean water scarcity problems and phosphorus reserves are likely to be depleted in the near future. Still, a large amount of clean water is used to transport excreta through sewer systems. Most of the wastewater generated worldwide is discharged untreated into aquatic systems and leads to water pollution and loss of valuable nutrients. In Hanoi, Vietnam's capital city, high population and economic growth as well as industrialisation have led to a decrease in groundwater level and to serious river and lake pollution. A probabilistic model, simulating the impact of measures on groundwater abstraction and nutrient recovery, was used to determine the impact of policy changes in Hanoi. The results obtained reveal that harmonising environmental sanitation and agricultural systems with one another will considerably increase nutrient recovery for food production, lower expenditure for artificial fertilisers and reduce the nutrient load into the environment. The model can be applied in urban areas of developing countries to assist in the design of environmental sanitation concepts.

Guideline for the safe use of wastewater, excreta and greywater

2006 | WHO, UNEP

The ultimate aim of these Guidelines is to protect and promote public health. Adequate capacity is required at the national level to maximize the benefit of the use of wastewater, excreta and greywater in agriculture and aquaculture, to minimize the health risks involved and to promote proper environmental management, ensuring long-term sustainability. An essential element of this national capacity consists of an enabling policy environment.  This chapter summarizes the information needed to formulate decision-making criteria, establish decision-making procedures and create effective institutional arrangements for their implementation.    The Guidelines are presented in four separate volumes: Guidelines for the safe use of wastewater, excreta and greywater. Volume 1: Policy and regulatory aspects Guidelines for the safe use of wastewater, excreta and greywater. Volume 2: Wastewater use in agriculture Guidelines for the safe use of wastwater, excreta and greywater. Volume 3: Wastewater and excreta use in aquaculture Guidelines for the safe use of wastwater, excreta and greywater. Volume 4: Excreta and greywater use in agriculture

Tonle Sap Rural Water Supply and Sanitation Sector Project: An ADB-funded Latrine-Building Project in Cambodia

| KOICA, UNEP, caps

Water and sanitation are one of the most pressing issues facing people in rural Cambodia, especially around the Tonle Sap Lake and river basin. Of particular difficulty for sanitation advocates in Cambodia is the old habit of open defecation, with the result of exposing human excreta to the environment. This leads to water and soil contamination and to widespread disease outbreaks. For the many ‘floating communities’ of people living on the lake itself, this is an even larger problem, due to their direct contact with the water. The UN estimated that, in 2008, only 23\% of rural residents and 82\% of urban residents had access to improved sanitation, which means the country still has a long way to go to achieving ‘sanitation for all’. Indeed, rural water coverage is the second lowest in Asia, while infant mortality rates – due in part to high levels of waterborne disease – are the second highest in Asia.

An Environmental Assessment Of The Bay Of Bengal Region

|

This document is the final report of an environmental assessment in the Bay of Bengal carried out between April 1991 and February 1993, with special reference to fisheries. It includes edited versions of the status reports from every member country of the Bay of Bengal Programme (BOBP). They were presented at the regional workshop held in Colombo, February 2-6, 1993at the conclusion of the assessment. The objective was to assess the problems of environmental degradation in the coastal ecosystems in the Bay of Bengal by reviewing the existing information, analyzing available data and collating it all as a fundamental information base. In the long-term, the project could result in recommendations for coordinated activities in the countries as well as the region to achieve sustainable productivity from the coastal ecosystems and reduce the negative effects on the fisheries resources.

The kNOwWaste Knowledge Platform was developed through a Project Cooperation Agreement funding by UNEP on 2016. The platform provides data and information on holistic waste management to stakeholders in Asia and the Pacific region. The platform was developed with the following aims: generate and consolidate data or information on holistic waste management, transform data into easily comprehensible outputs for use by key stakeholders, map out and disseminate information on international waste management projects under the GPWM and UNEP projects as well as other international partners, and provide capacity building support through dissemination of data or information support for relevant stakeholders on holistic waste and waste management system.
