Celebrating Women in Water

Today, we celebrate International Women's Day. I especially would like to extend my warmest regards to all Women in Water. Kudos to you, and may you keep working hard towards sustainable and equitable access to safe water supply and sanitation services. 

Women play different roles in the water sector. This includes the traditional chore of fetching water to ensure that the family has enough for cooking, drinking, bathing, laundry and gardening; and professional roles such as water engineers, water researchers, policy, environmentalist, hydrologists, environmentalists, managers, just to mention a few. 

This year's call for change is driven by the campaign theme "Choose to challenge".  this can be achieved by:

• Calling out on unequal access to water and sanitation services
• Help forge inclusive enrolment in STEM subjects in Higher education institutions
• Help remove barriers to female employment in the water sector
• Remind the world that Women deserve a place at the decision-making table
• Sharing women in achievements
• AND much more!

Join the campaign today!

If you are a woman working in the water sector and would like to connect with other women professionals to share experiences and ideas, you can join the Community of Women in Water (CWiW), a global networking platform supporting women working to solve water issues!

I would also love to connect with other young women professionals. Check out my LinkedIn profile. 

Celebrating Wetlands!

 The 2nd of February was World Wetlands Day. 

This is a day set to celebrate and appreciate the beautiful habitats. It also serves to remind us that we need to conserve and protect this vital natural resource. 

So, what exactly is a wetland?

According to UNESCO, "wetlands are ecosystems seasonally or permanently saturated with water. This can include all lakes and rivers, underground aquifers, swamps and marshes, wet grasslands, peatlands, oases, estuaries, deltas and tidal flats, mangroves and other coastal areas, coral reefs, and all human-made sites such as fish ponds, rice paddies, reservoirs and salt pans". 

What is the value of wetlands?

• Promote biodiversity - wetlands are home to many plant, fish and wildlife species.
• Water purification - wetlands plants remove pollutants through sediment trapping, nutrient removal and chemical detoxification. 
• Water storage- wetlands are often referred to as natural sponges because of their ability to soak up water during high runoff periods and release it slowly into the ground. This helps control the severity of floods and erosion.
• Their ability to recharge groundwater helps in addressing water scarcity issues.
• Wetlands may reduce risk to public safety and damage to property due to flood water or stormwater runoff.
• They offer recreational and economic benefits through hiking, boat rides, fishing, bird watching, canoeing and photography. 
• Provide products for home use and crafts, including fuelwood for cooking, fish, wild rice and fruits for food,  reeds for weaving baskets and mats,  thatch for roofing, fibres for textiles and papermaking, and timber for building. Medicines can be extracted from tree barks, leaves, and fruits, and the plants also provide tannins and dyes. 
• The diverse and abundant vegetation and animal species give wetlands a high aesthetic value. These visually rich environments usually attract people to see wildlife, have picnics and capture nature's beauty through the camera lenses. 
• Wetlands provide opportunities for education, research and innovation. Researchers can study the historical changes in climate and vegetation over thousands of years, which can help develop future solutions. Also, by studying and understanding the functioning of wetlands, new solutions to engineering and design can be drawn, e.g. through biomimicry.  

How can we conserve wetlands?

Wetlands are often under threat from many human activities, and it takes everyone's effort to ensure that the wetlands are safe and protected. This can be done by:

• Not dumping waste in wetlands
• Not cultivating in wetlands
• Not building and settling in wetlands
• Adopting a wetland stream as a community or school and closely monitor and protect it 
• Raising awareness in your community, school and university
• Guard and being vigilant against any element that could threaten the existence and functionality of wetlands
• Avoid overutilization of wetland resources

World Toilet Day 2020

 Today is World Toilet Day.

This is a day marked by the United Nations' to celebrate and raise awareness on sustainable sanitation. Sustainable Development Goal 6 calls for "clean water and sanitation for all", with SDG 6.2 particularly focusing on "Sanitation and hygiene". 

Why?

It is estimated that approximately 4.2 billion people lack access to safe sanitation globally, and of these, 673 million practice open defecation. This is a great cause for concern, given how sanitation is linked to our health and dignity. Poor sanitation is associated with the transmission and spread of water-borne diseases such as cholera, typhoid, diarrhoea, dysentery, hepatitis A and Polio. Recent experiences from Covid-19 have also shown the world the importance of good sanitation facilities for preventing the spread of infectious diseases. In addition, poor sanitation may result in loss of education, especially for girls; and increase the risk of sexual assault.

This Year's Theme

The theme of World Toilet Day 2020 is "Sustainable sanitation and climate change". A proper toilet is connected to a sanitation system that collects, transports and treats human waste. Most countries use combined sewer systems to collect wastewater from residential/ industrial/commercial areas to the water treatment plants. These systems are under threat from climate change, such as flooding, drought and rising sea levels. These events are becoming more frequent and more extreme, posing a high risk to the functioning of different parts of the sanitation system. Toilets, sewer pipes and tanks, treatment plant can easily be damaged, which may lead to overflows of raw sewage into wells, rivers and food crops, posing a public health hazard. There is, therefore, an urgent need for building resilient sanitation systems. 

What Role Can you play?

1. Smart Innovations: 

A sustainable sanitation system means providing a  reliable system that can safely collect the faeces,  dispose of and treat them, and facilitate safe reuse. 

• Water-efficient: Toilets use a lot of water for flushing. A regular toilet can use between 5 and 15 litres of water (usually potable) per flush. A sustainable and smart sanitation innovation means a toilet that uses as little water as possible to flush out the waste. Since toilet flushing doesn't require high-quality potable water, there is a need to invest in a water reuse system or connect the toilet to a rainwater harvesting system. Recent smart sanitation innovations are trying to separate urine and faeces using a urine diversion dry toilet. However, more work needs to be done to make it financially sustainable and socially acceptable.
• Energy efficiency: Most sanitation systems are energy-intensive: therefore, a smart innovation will focus on building an energy-efficient system and lowering greenhouse gas emissions. There is also a possibility of using biogas from human waste to produce greener energy.

2. Rethink, Reduce, Reuse & Recycle

There are different processes involved in the sanitation cycle, all providing an opportunity for rethinking, reducing, reusing, or recycling. 

• Rethink before practising open defecation or defecating on the floor. Do your part to keep the sanitation facilities clean. Also, Rethink before ignoring a burst sewer pipe in your neighbourhood; report it to the suitable authorities as soon as possible.
• Reduce unnecessary flushing and the amount of water you use for toilet flushing. Invest in a low-flush toilet or a dual flush system. During the rain season, harvest some rainwater and use it to flush the toilet. 
• Reuse: Collect water from the dishwasher or washing machine and re-use it to flush the toilet. You can also connect your washbasin to the toilet water tank so that water can be collected and used for flushing after someone has used the washbasin.
• Recycle: at a bigger scale, biogas from human waste can be captured and used to produce energy. Recent studies have also been looking at producing charcoal briquettes using human waste. On the other hand, urine is reported to have a lot of nutritional benefits. Where urine diversion toilets are used, urine has been used to produce liquid fertilizer, and it is reported to provide an excellent source of nitrogen, phosphorus and potassium to plants. The options are limitless!

3. Invest and support sanitation initiatives

This could be through raising awareness in your community or provide funding for research purposes etc. 

From the points highlighted above, it is clear that everyone has a role to play in the sanitation game. Let us come together and pledge ourselves to create more solutions for a better future.

SANITATION FOR ALL BY 2030!
