Experts expect that 50 percent of the world population will live in areas with water shortages by 2025. For cities in South Africa, India and China, this crisis is already becoming a reality. So what solutions are there for the shortage of this valuable resource? Water filtration systems and desalination are a few, although many water treatment solutions have not been environmentally friendly and desalination has proven to be costly. However, a lot has changed in water treatment over the years. Here are a few improvements and advancements that could prove promising for the future of potable water, including drinkable ocean water.
Water Softeners and Filtration Systems
Water softeners and filtration systems have gained a negative reputation due to the salt they use and the wastewater they produce that ends up in aquatic environments. However, advancements in these areas have led to softeners that use salt more efficiently and newer equipment reducing water usage and conserving that precious resource. New technology has decreased the usage of both water and salt by 50 percent.
Manufacturers have established ways to achieve high efficiencies by focusing on providing products that are better-performing and able to dictate the amount of water they use during maintenance functions, as well as making larger filtration cartridges that extend the replacement cycle times. Manufacturers have even designed new technology to monitor water usage in the home and adjust to match the household’s habits.
A top priority of the water treatment industry is to develop ways to address contamination while maintaining sustainability. The improvements that manufacturers are making to reverse osmosis (R.O.) systems reflect that.
R.O. systems can result in a reduction of the purchase of bottled water due to how greatly they diminish contaminants. However, the systems still have room for improvement due to the amount of wastewater they produce. The technology to reduce wastewater exists internationally and now the U.S. is looking to make the same progress.
Desalination
If people could drink from the ocean, there would be more than enough water for everyone. However, it would be necessary to remove the salt first.
There are about 2.2 billion people who do not have access to clean drinking water. For thousands of years, turning seawater into drinking water has been an option for this ongoing problem, although the process tends to be expensive and inefficient because it requires a lot of energy.
Kamalesh Sirkar, a chemical engineering professor at the New Jersey Institute of Technology, has a new process that promises to make a difference. His direct-contact membrane distillation (DCMD) system heats seawater across a plastic membrane containing tubes filled with cold distilled water. The tubes have pores so that the water vapor that collects on them can penetrate into them, but not salt. The vapor can then condense back into liquid water.
This efficient system can produce 21 gallons of drinking water per 26 gallons of seawater, which is twice as much as most existing desalination technology. The downside of DCMD is the requirement of a heat source to prevent the water temperature on either side of the membrane from equalizing, although there is the potential of recycling waste heat to run the system.
A team of international scientists has achieved a similar accomplishment by using the sun to produce high-quality potable water. This process can meet the needs of an entire family at a cost of about $100 without using electricity. This team, consisting of scientists from MIT in the U.S. and Shanghai Jiao Tong University in China, believes that its system can provide water to islands and coastal areas that do not have reliable electricity but have access to seawater. With this system, the team produced 1.5 gallons of fresh drinking water every hour for every square meter of the solar collecting area.
GivePower
Recently in Kenya, a nonprofit called GivePower has been able to successfully use solar power to create drinkable ocean water. In July 2018, a new desalination system began operations on the coast of Kiunga that can create 19,800 gallons of drinking water every day. That is enough for 25,000 people. This nonprofit’s main focus has been to provide solar-energy systems to developing countries. The organization has installed solar grids in 2,650 locations across 17 countries in places like schools, medical clinics and villages.
The success of this system is in finding a way to pull water out of the ocean in a scalable, sustainable way. The president of GivePower, Hayes Barnard, hopes to open similar facilities around the world, providing fresh water to people who struggle to get it on a daily basis.
At the rate that the population has been increasing, a freshwater crisis appears imminent. However, with the work that experts are putting into finding a solution, the possibilities for the future look bright. With environmentally friendly filtration systems and the successful production of drinkable ocean water, the population will all be able to drink deeply since there will be enough to go around.

The World Cocoa Foundation: Sustainable Cocoa for a Rich Future
Reasons Behind Issues in the Cocoa Industry
Partly to blame is the common practice of sharecropping. In regions where cocoa is most heavily produced, sharecropping restricts farmers’ ability to significantly alter their land for sustainable use. It disincentivizes farmers to make rehabilitation investments. Moreover, monoculture crops – singular crops produced over a large area of land – inhibit crop diversity and make crops more susceptible to pests and diseases.
According to NPR, high rainfall, lower demand for chocolate and price-fixing have also contributed to a decrease in cocoa prices. This has led to an increase in low wages and high debts for cocoa farmers, resulting in chronic poverty. Charlotte Grant, the Communications and Marketing Manager for the World Cocoa Foundation believes that poverty leads to issues such as child labor and deforestation.
“We fear that the well-being of farmers will not improve unless the cocoa supply chain becomes more sustainable,” said Grant. Without any intervention, the global cocoa industry faces an uncertain and unstable future. Fortunately, the World Cocoa Foundation has given cocoa farmers a sense of renewed hope.
A Rich History
The U.S. chocolate industry created the Chocolate Manufacturers Association (CMA) in 1923 to serve cocoa producers by funding research, promoting chocolate consumption and lobbying Congress and government agencies. When the CMA determined a new model for cocoa sustainability was necessary, it formed the International Cocoa Research and Education Foundation in 1995. In 2000, the foundation was renamed the World Cocoa Foundation. Its main focus is on cocoa research and educational programs.
In the late 2000s, with funding from the Bill and Melinda Gates Foundation and the U.S. Agency for International Development, WCF began administering large-scale projects that emphasized productivity, higher-wages for farmers, the reduction of child labor, scientific research and community strength. Today, with more than 100 members, the vision of WCF is clear: “A sustainable and thriving cocoa sector – where farmers prosper, cocoa-growing communities are empowered, human rights are respected, and the environment is conserved.”
The Work of WCF
WCF maintains a diverse range of programs across several regions, including program partnerships with other NGOs. Initiatives like CocoaAction, Cocoa and Forests Initiative, Climate Smart Cocoa, Cocoa Livelihoods Program and African Cocoa Initiative II are addressing the specific needs of cocoa-producing communities.
WCF launched the Cocoa Livelihoods Program in 2009. This program works to increase cocoa farmer productivity. Through training and education, CLP advances four primary objectives. It works to advance industry initiatives, provide a “full-package” of services to farmers, promote food crops and empower women. With more than 15 company partners, CLP serves impacted communities in Cameroon, Ghana, Nigeria and Côte d’Ivoire.
With the goal of increased stakeholder collaboration, WCF established the CocoaAction initiative in 2014. CocoaAction offers a Monitoring & Evaluation Guide that provides data collection in communities as well as a Community Development Manual. It provides company partners with an outline for the design and implementation necessary for sustainable Cocoa production.
Making Chocolate Sustainable
In 2019, as part of the Cocoa and Forest Initiatives, 34 chocolate companies, along with the governments of Côte d’Ivoire and Ghana, released official action plans detailing the new steps they are taking to address climate change and cocoa sustainability. The initiative aims to end deforestation and replace vegetation in impacted forest areas. The Climate Smart Cocoa initiative acknowledges the impact of climate change on cocoa crops. It seeks to examine better risk and investment strategies to strengthen the global cocoa market.
Partnering with USAID and several private sector partners, the African Cocoa Initiative II emphasizes the importance of economically sustainable and economically viable cocoa production. According to the ACI II annual report, more than “two million smallholder farmers” rely on cocoa farming for income. Therefore, “a healthy and sustainable cocoa industry means opportunity for economic growth and poverty alleviation in the region.”
A Sweet and Sustainable Future
In the past two decades, the World Cocoa Foundation has benefited countless farmers and their communities. Through training, education and community partnerships, WCF continues to strengthen the cocoa industry. By becoming more informed about the issues in the cocoa industry and what is currently being done to resolve them, people can make a difference, according to Grant. It is important to research preferred chocolate manufactures and make sure they are using sustainable, fair trade practices. By getting involved and sharing important information about the cocoa industry, consumers can make a difference in cocoa farmers’ lives.

7 Venezuelan Humanitarian Crisis Aid Efforts
Venezuela has been marred by a humanitarian crisis for several years, and the situation persists. As policy forum the Wilson Center explains, more than four million Venezuelans have left the country, most since 2015. This makes Venezuela the second most common country of origin for displaced people worldwide, behind only Syria.
In breaking down the crisis, the Wilson Center says Venezuela has “widespread poverty and chronic shortages of food, medicine, and other basic necessities,” and as The Borgen Project reported last year, cases of malnutrition and disease are rampant. These issues come as a consequence of economic mismanagement, official corruption and decreasing oil prices between 2013 and 2016.
An example of that purported corruption — and perhaps the most public element of Venezuela’s overall state — is that Venezuela’s current President Nicolás Maduro won a second term in the 2018 election, despite being largely blamed for helping further the once-wealthy nation’s free fall that began under Maduro’s predecessor Hugo Chávez. Much of the world believes Maduro’s re-election was falsely won through corrupt tactics, and instead back key opposition entity the Lima Group’s leader Juan Guaido. The group seeks to install Guaido in Maduro’s place, but has as yet been unsuccessful.
Still, as dire as the situation remains for Venezuela, several efforts have been launched and entities mobilized to help the Venezuelan people. Here are seven organizations or initiatives aimed at assuaging the long-standing and growing Venezuelan humanitarian crisis.

5 African Agritech Startups Tackling Poverty
The World Bank predicts that agribusiness in Africa will grow to become a $1 trillion industry by 2030. This growth impacts poverty reduction efforts. For every 1 percent increase in agricultural GDP, poverty in the region decreases by 1 percent. Food security and stable growth in the region can be obtained by investments in agriculture. Specifically, a large branch of agriculture business on the rise is agricultural-tech in Sub-Saharan Africa. With African agritech startups launching in 2010, exponential growth has been seen since.
Agritech companies, or disruptive agricultural technologies (DATs), aim to develop solutions to ongoing issues in the form of solar devices, mobile apps and even bio-fortified foods. These companies help farmers in two ways: increasing produce yield by 3-5x the baseline and/or connecting farmers directly to buyers and affordable equipment, effectively cutting out the middleman. These technological advances help farmers increase their output, efficiency and access to markets. With the help of agritech, farmers can combat a lack of regional resources and reduce poverty.

History of Drought in Thailand
Thailand is currently facing a drought so severe that experts say that it is the worst drought in the previous 40 years. The low-lying water level of the Chao Phraya River, which is the main source of water for Thailand’s capital city Bangkok, has exasperated the current drought in Thailand. The issue is becoming so troublesome that people in and around Bangkok are experiencing water shortages. In addition, the decline in the water level of the Chao Phraya River has resulted in seawater entering the public water source, and many reported tasting salty water dispensed from their water tabs. Water salination not only puts drinking water in jeopardy, but it also affects water-reliant industries such as agriculture and various manufacturing plants.
Key questions that people should consider are: What is the source of the current drought in Thailand? Who does this drought primarily affect? Is this drought a new problem, or a recurrent one?
Climate in Thailand
The Unpredictability of the Weather in Thailand
Agricultural Impact of Weather Patterns
The unpredictable precipitation in Thailand is a major problem, specifically for Thailand’s agricultural sector. Until recently, Thailand was the largest exporter of rice in Asia. Nicknamed the “rice bowl of Asia,” Thailand exported $5.6 billion worth of rice in 2018 or 22.7 percent of the world’s rice export. This sector experienced a great impact from the drought as Thailand’s agricultural sector utilizes 70 percent of Thailand’s total water supply. Another industry facing a huge impact is Thailand’s sugar industry, bringing the Thai sugar output to a nine-year low of 10.5 million tons.
Thai Government’s Measures to Combat Drought
As a result, the Thai government has promoted projects and campaigns which encouraged water conservation. Thailand has implemented dams and reservoirs to play a major part in relieving drought in the country. Thailand initiated the majority of the construction of its major dams and reservoirs, such as the Chao Phraya Division Dam, the Bhumibol and Sirikit Dams and the Greater Chao Phraya Irrigation, after the Second World War.
In 2019, for example, the Royal Irrigation Department of the Thai government designed two rice planting areas in the central plains to double as water catchment areas. Currently, the government is planning to build 421 water storage facilities to support farmers who are suffering from the current drought. Due to the intensity of the current drought in Thailand, the Thai Irrigation Department is raising slight concerns about the efficacy of these dams and reservoirs.
Drought in Thailand has been a long occurring issue that affects numerous aspects of Thai society. Specifically, the negative impact on the agricultural sector not only affects the farmers but fluctuating food costs also affect Thai consumers. The irregular precipitation rate, that the climate change of the last decades caused, is further worsening the drought in Thailand, thus creating a cyclic decline of the economy and water sanitation and access.
The Thai government is taking active measures to deal with these issues where the aim is to provide continuous dedication to improving water conservation. The governments’ intention is that eventually, droughts in Thailand will become stories of the past.
