Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route. For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis, cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few.
Community-led total sanitation (CLTS) is an approach used mainly in developing countries to improve sanitation and hygiene practices in a community. The approach tries to achieve behavior change in mainly rural people by a process of "triggering", leading to spontaneous and long-term abandonment of open defecation practices. It focuses on spontaneous and long-lasting behavior change of an entire community. The term "triggering" is central to the CLTS process: It refers to ways of igniting community interest in ending open defecation, usually by building simple toilets, such as pit latrines. CLTS involves actions leading to increased self-respect and pride in one's community. It also involves shame and disgust about one's own open defecation behaviors. CLTS takes an approach to rural sanitation that works without hardware subsidies and that facilitates communities to recognize the problem of open defecation and take collective action to clean up and become "open defecation free".
The Aga Khan Planning and Building Service(AKPBS) was established in 1980 as an agency of the Aga Khan Development Network (AKDN). The agency works to improve the built environment, particularly housing design and construction, village planning, natural hazard mitigation, environmental sanitation, water supplies, and other living conditions. It does this by providing material, technical assistance and applied research, as well as planning and building management services for communities in both rural and urban areas.
Drinking water supply and sanitation coverage in Honduras has increased significantly in the last decades. However, the sector is still characterized by poor service quality and poor efficiency in many places. Coverage gaps still remain, particularly in rural areas.
Water supply and sanitation in Indonesia is characterized by poor levels of access and service quality. More than 16 million people lack access to an at least basic water source and almost 33 million of the country's 275 million population has no access to at least basic sanitation. Only about 2% of people have access to sewerage in urban areas; this is one of the lowest in the world among middle-income countries. Water pollution is widespread on Bali and Java. Women in Jakarta report spending US$11 per month on boiling water, implying a significant burden for the poor.
The water supply and sanitation sector in Ghana is a sector that is in charge of the supply of healthy water and also improves the sanitation of water bodies in the country.
Drinking water supply and sanitation in Pakistan is characterized by some achievements and many challenges. In 2020, 68% Pakistanis, 72% Indians, 54% Bangladeshi had access to the basic sanitation facilities. Despite high population growth the country has increased the share of the population with access to an improved water source from 85% in 1990 to 92% in 2010, although this does not necessarily mean that the water from these sources is safe to drink. The share with access to improved sanitation increased from 27% to 38% during the same period, according to the Joint Monitoring Program for Water Supply and Sanitation. There has also been considerable innovation at the grass-root level, in particular concerning sanitation. The Orangi Pilot Project in Karachi and community-led total sanitation in rural areas are two examples of such innovation.
The Building and Construction Improvement Program(BACIP) is a program of the Aga Khan Planning and Building Service, Pakistan (AKPBS,P) that is engaged in developing and promoting solutions to housing and built environment-related issues of rural communities living in Gilgit-Baltistan and the province of Sindh.
Water supply and sanitation in Tanzania is characterised by: decreasing access to at least basic water sources in the 2000s, steady access to some form of sanitation, intermittent water supply and generally low quality of service. Many utilities are barely able to cover their operation and maintenance costs through revenues due to low tariffs and poor efficiency. There are significant regional differences and the best performing utilities are Arusha and Tanga.
WASH is an acronym that stands for "water, sanitation and hygiene". It is used widely by non-governmental organizations and aid agencies in developing countries. The purposes of providing access to WASH services include achieving public health gains, improving human dignity in the case of sanitation, implementing the human right to water and sanitation, reducing the burden of collecting drinking water for women, reducing risks of violence against women, improving education and health outcomes at schools and health facilities, and reducing water pollution. Access to WASH services is also an important component of water security. Universal, affordable and sustainable access to WASH is a key issue within international development and is the focus of the first two targets of Sustainable Development Goal 6. Targets 6.1 and 6.2 aim at equitable and accessible water and sanitation for all. In 2017, it was estimated that 2.3 billion people live without basic sanitation facilities and 844 million people live without access to safe and clean drinking water.
School hygiene or school hygiene education is a healthcare science, a form of the wider school health education. The primary aims of school hygiene education is to improve behavior through useful practices connected to personal, water, food, domestic and public hygiene. Also, it aims to protect water and food supplies and to safely manage environmental factors.
Relief International is an international non-governmental organization (NGO) that partners with communities impacted by conflict, climate change, and disaster to save lives, build greater resilience, and promote long-term health and wellbeing. Relief International is a global alliance of four organizations: Relief International Inc, Relief International UK, Relief International France and Relief International Europe.
Water issues in developing countries include scarcity of drinking water, poor infrastructure for water and sanitation access, water pollution, and low levels of water security. Over one billion people in developing countries have inadequate access to clean water. The main barriers to addressing water problems in developing nations include poverty, costs of infrastructure, and poor governance. The effects of climate change on the water cycle can make these problems worse.
Open defecation is the human practice of defecating outside rather than into a toilet. People may choose fields, bushes, forests, ditches, streets, canals, or other open spaces for defecation. They do so either because they do not have a toilet readily accessible or due to traditional cultural practices. The practice is common where sanitation infrastructure and services are not available. Even if toilets are available, behavior change efforts may still be needed to promote the use of toilets. 'Open defecation free' (ODF) is a term used to describe communities that have shifted to using toilets instead of open defecation. This can happen, for example, after community-led total sanitation programs have been implemented.
Water supply and sanitation in Zimbabwe is defined by many small scale successful programs but also by a general lack of improved water and sanitation systems for the majority of Zimbabwe. Water supply and sanitation in Zimbabwe faces significant challenges, marked by both successful localized efforts and widespread deficiencies in infrastructure. According to the 2019 Multiple Indicator Cluster Surveys (MICS), conducted by UNICEF, disparities persist in access to clean drinking water and sanitation facilities. While overall access to improved drinking water sources increased to 77.1% in 2019 from 76.1% in 2014, significant gaps remain between urban and rural areas, as well as within urban centers. For instance, 97.3% of urban households have access to improved water sources compared to only 67.9% of rural households. Similarly, disparities exist across regions, with Harare boasting the highest access at 96.6%, contrasting sharply with 64.8% in Matabeleland South. Additionally, approximately 67.8% of households have access to improved, non-shared sanitation facilities, indicating ongoing challenges in this domain. Urban areas, in particular, grapple with chronic water shortages amid rising consumption demands. There are many factors which continue to determine the nature, for the foreseeable future, of water supply and sanitation in Zimbabwe. Three major factors are the severely depressed state of the Zimbabwean economy, the willingness of foreign aid organizations to build and finance infrastructure projects, and the political stability of the Zimbabwean state.
Emergency sanitation is the management and technical processes required to provide sanitation in emergency situations. Emergency sanitation is required during humanitarian relief operations for refugees, people affected by natural disasters and internally displaced persons. There are three phases of emergency response: Immediate, short term and long term. In the immediate phase, the focus is on managing open defecation, and toilet technologies might include very basic latrines, pit latrines, bucket toilets, container-based toilets, chemical toilets. The short term phase might also involve technologies such as urine-diverting dry toilets, septic tanks, decentralized wastewater systems. Providing handwashing facilities and management of fecal sludge are also part of emergency sanitation.
Water supply and sanitation in Mali is characterized by serious challenges. Unclean water can lead to many diseases that are potentially fatal. Water supply issues lead to a variety of issues throughout the country.
Laos is a nation with plentiful surface water and broad rivers, but outside of cities there is little infrastructure to make that water clean and accessible. Very little improvement has been made since the end of the Laotian Civil War in 1975, especially compared to peer nations such as Thailand. By 2015, 76% of Laotians nationwide were estimated to have access to “improved” water, while 71% were estimated to have access to “improved” sanitation.
Lesotho is a mountainous and fairly 'water-rich country', but suffers from a lack of clean drinking water due to inadequate sanitation. In recent decades, with the construction of dams for the Lesotho Highlands Water Project (LHWP), Lesotho has become the main provider of water to parts of northern South Africa. Despite the economic and infrastructure development occasioned by the LHWP, waterborne diseases are common in the country and the infant mortality rate from them is high. In 2017, a project to improve the rural water supply in the Lesotho Lowlands was funded by the Global Environment Facility and the African Development Bank, and is ongoing.
The Aga Khan Agency for Habitat (AKAH) was established in 2016 and is part of the Aga Khan Development Network (AKDN). It is an umbrella of AKDN agencies and programs that have provided aid and delivered training on habitat and disaster preparedness since the 1990s.
