Charting an eco-future for Yangtze and China

Stephen P. Groff

The majestic Yangtze — the longest river in the world flowing through a single country — nurtures an area of more than 2 million square kilometers, or about one-fifth of China. It is also one of the busiest inland rivers on the planet and about 400 million people rely on it for their water needs.

The Yangtze and its fertile basin generate around 45 percent of China’s gross domestic product  and have been key drivers of the economic growth that has lifted hundreds of millions of people out of poverty in recent decades. But that prosperity has taken a toll — increasingly in the form of poor agriculture and rural waste management practices, rather than the process of urbanization alone. In 2010, water used to irrigate fertilized fields became a greater source of pollution in Yangtze River than urban water pollution.

This heightened pollution in the main river has severely reduced the quality of drinking water, creating other health problems as well as reducing biodiversity. Smaller lakes and tributaries also suffer from high levels of pollution. Besides, dams, floods, and deforestation have made the riverbanks less stable and more prone to landslides. And climate change will likely worsen these effects over time.

In referring to the Yangtze as the country’s “mother river” and calling for “a green development path which puts ecology first”, the Chinese government recognizes these threats and is implementing initiatives to address the issues. This is also consistent with the country’s “rural vitalization” strategy, a national initiative to protect the environment, modernize agriculture, and improve the lives of people living in the countryside by 2035.

Much of the work to improve the river and its surroundings is captured in the government’s Yangtze River Economic Belt Development Plan. The plan re-orients economic activities around the river toward green development, giving equal weight to economic growth and environmental protection. This ambitious program will support green development initiatives particularly in rural areas that are most in need of development.

The plan sets a target to significantly improve the environmental quality of the Yangtze, aiming for more than 75 percent of the region’s water meeting Class III standard or above and more than 40 percent of the area protected by forest coverage by 2020. This is to be done by promoting environmental protection, improving the management of water resources, promoting green industries, and improving transport in the region.

For China to achieve the ecological and environmental targets for the Yangtze and keep its vision of overall rural vitalization on track, it is important to strengthen the links between the Yangtze River Economic Belt program and the rural vitalization strategy in a “two-pronged” approach.

In keeping with this idea, the Asian Development Bank has programmed $2 billion in strategic investments in agricultural modernization and environmental improvement initiatives up to 2020. Rural vitalization also presents an excellent opportunity to integrate innovative technologies, such as the “internet plus agriculture” model, blockchain technologies, and new decentralized rural wastewater and sanitation treatment systems.

Cooperation and planning with and between provinces and across different sectors will also ensure a fully integrated approach to the many common problems suffered in the Yangtze River basin and in other rural areas. Establishing a conducive and coordinated mix of policies and regulations that clearly prescribe rights and responsibilities will ensure that the work has a lasting effect.

Moreover, it is essential that planning for rural and river recovery takes a holistic approach looking at all the interconnecting issues along the ecological value chain, from mountains to oceans, since only this will ensure there is a full, long-term transformation. Sharing information across institutions in China and with countries in the region can help with this.

The importance of the Yangtze to China cannot be overstated. The government has made it clear that the river’s rehabilitation is a high priority and has set an ambitious deadline for significant improvements. Coordinated, long-term planning and actions will revitalize the rural economy and help restore the Yangtze to its full, well-deserved glory.

Prevailing Plastic Pollution in Pakistan

Muhammad Usman Ghani

Published

on

In recent times our globe has trodden the path of development and advancement by leaps and bounds. This advancement and progress have taken place up to such extent that a lower class citizen finds himself besieged by multiple machines in his small home. The excess services of the technology have taken the world by storm because it has facilitated humanity with astonishing services. Advancement in technology has a direct link with that of globalization. With the advancement in globalization, the trends of people have altered their preferences. During the last decade, there is a glaring rise in the trends of shopping. The drifts of globalization with capitalism have enticed people to widen their demands. And obviously, one can witness that even a beggar seems to purchase some eatable or aught. With the augmentation in the trends of business and purchasing, there is rampant use of plastic bags and plastic commodities. But this wonder of plastic got a little out of hand.

However, in this technological, globalized, and capitalistic era, our biodiversity with worth trillion dollars is on a perilous verge. Overuse of technological accessories, industrialization, mobilization, and globalization from one perspective have posed a threat to our ecosystem. The one darkest commodity of this globalized and technologically sophisticated world is the menace of plastic. Yes, during these times when the advantages of technology and globalization are getting much publicity, they have posed threat on either side as well. Plastic is one of these perils and has saturated our environment. The invention of this commodity has completely invaded our lives. During these times, everything is at least partly fabricated from plastic. Our clothes, items of furniture, houses, bags, and several items that surround us possess a specific share of plastic in them. In short, our lives are turning into plastic.

Plastic is the biggest threat to biodiversity. The question that arises why it is a threat to the environment? The answer is obvious that plastic is non-biodegradable (not able to be decomposed). The plastic bags that we see on shopping centers usually take 10-100 years to decompose and normal plastic products take 450 years to decompose. According to the report, the world is currently producing nearly 300 million tons of plastic each year. Now imagine for a moment that such a prolific quantity of plastic that is being produced every year, how long it will take to decompose? Centuries of course.

Another question that rears is the plastic that has produced till date, created the perplexity up to which extent? The answer is that it has wreaked havoc in the environment. Particularly, it has harmed marine life. Since heaps of garbage are dumped into the sea, so that refuse involves plastic in it. As seafood is an important source of protein; pollution and damage propagated by plastic are immeasurable. Over 600 marine species are being harmed by plastic pollution every day. Aforementioned that plastic takes many years to decompose, so marine animals can’t digest it. When they ingest plastic bags, gills are wrapped by the plastic bags. In this way, suffocation occurs which leads them to death. Their death brings about further pollution to the sea. By this mean, we are squandering our sea boon.

The issue doesn’t end here, the life on the earth crust and in the atmosphere is also not safe from this menace. Many people inhabited in small towns and village burn plastic, in order to annihilate. The burning of plastic causes damage to the atmosphere as plastic comprises poisonous chemicals. The polluted air when inhaled by humans and animals affect their health and can cause respiratory problems. Likewise, when plastic is dumped in landfills, it interacts with water and forms hazardous chemicals. When these chemicals seep underground, they degrade the water quality. In these ways, plastic is damaging our globe.

Following analyzing the downside of plastic, the next question inevitably dominates the thinking that how much the government of Pakistan is serious to sort out this issue. The answer to this question is the government is iota interested in this matter. Almost eight months have passed yet the government seems uninterested in this matter. Around 55 billion plastic bags are being used annually in Pakistan. In my city or district, I see at every outlet the plastic bags hung. Every customer carries the eatable or necessity item in the plastic bag. There is no observance of the ban on the use of the plastic bag. On the contrary, many European countries have devised plans and passed the rules against the use of plastic bags. The incumbent government is just good at reprimanding the previous governments. Pakistan is among the top 10 polluted countries and doubtlessly plastic pollution is responsible for bringing at status quo. The government should impose a ban on plastic bag manufacturing factories. Also, it should abbreviate the use of plastic commodities.

Multiple convenient solutions have been proposed in combating plastic pollution. Switching to reusable bags would help a lot in reducing plastic pollution. Organic cotton grocery bags, canvas market bags, and, grab bags are the best alternatives to plastic bags. In 2016, after consuming five years searching through piles of waste, Japanese researchers found a strain of bacteria that naturally grew to eat away at polyethylene terephthalate, which is common plastic and known as polyester. This bacteria is known as Mutant Enzyme. The know-how of the proper way to recycle common plastics is necessary, can also do wonders. Arranging awareness seminars on the detrimental effects of plastic is yet another effective way.

Despite many proposed and effective solutions above the incumbent government is tethered to combat the menace of plastic. The government should be mindful that if we keep going on this trajectory, there will be more plastic than fish by 2050. The government, the NGO’s, social welfare organization, civil societies, and we as the unit should join hands together to fight that perilous issue lest it should late.

India advances ground-breaking plan to keep planet and people cool

India’s new comprehensive Cooling Action Plan targets an increase in sustainable cooling for the good of its population, while helping to fight climate change

Four years after temperatures hit the high forties in India, claiming over 2,000 lives, parts of the country are again baking in intense, and deadly, heatwaves. Throughout April and into May, the states of Madhya Pradesh, Maharashtra and Rajasthan have seen daily highs of 42°C.

As climate change increases, such temperatures are becoming the new normal. Combined with economic growth and urbanization, this brings a huge growth in cooling demand. The number of air conditioners in India is expected to rise from 15 million in 2011 to 240 million in 2030.

Cooling isn’t just about protecting against extreme temperatures. A recent study from the UN’s Sustainable Energy for All initiative puts India in the top nine countries at greatest risk from lack of access to cooling technology that also keeps food fresh, vaccines stable and children in education.

To give just a few examples, a quarter of vaccines in India arrive damaged because of broken or inefficient cold chains, while only four per cent of fresh produce is transported in refrigerated vehicles, leading to economic losses of US$4.5 billion annually.

Aware of these worrying statistics, the government launched earlier this year the India Cooling Action Plan, the first such holistic plan from any national government.

“Cooling is a developmental need, yet India has one of the lowest levels of access in the world,” says CK Mishra, Secretary at the Ministry for Environment, Forest and Climate Change. “To support economic growth and improve resilience, it is inevitable that India will embrace cooling.

“By accelerating and integrating policies, regulations, workforce training and research and development, this plan mobilizes government, industry and society to ensure thermal comfort for all while keeping to our international environmental commitments and not burdening ourselves with inefficient, expensive infrastructure and an overstretched power grid.

“The plan recognizes the significant role of accelerated action on building and appliance efficiency, and the economic and environmental benefits of new technologies such as thermal storage and district cooling.”

Energy efficiency a key approach

By 2038, the plan aims to reduce cooling demand by up to 25 per cent, refrigerant demand by 25–30 per cent and cooling energy requirements by up to 40 per cent. It aims to double farmers’ incomes by improving the cold chain and so wasting less food.

These are big goals, but experts believe India’s plan is sensible and achievable.

“Living in India you quickly understand the importance of keeping cool for your health and day-to-day functioning,” says Benjamin Hickman, a UN Environment technical advisor based in India. “This plan acknowledges head-on that Indian cooling demand will grow eightfold in 20 years and recommends a myriad of cross-cutting solutions that urgently need to be implemented and scaled up.”

Crucially, the plan also aligns India’s cooling growth with the Kigali Amendment to the Montreal Protocol. This international agreement obliges nations to phase down the use of hydrofluorocarbons (HFCs)—refrigerants that are thousands of times more potent greenhouse gases than carbon dioxide.

Globally, the agreement can deliver up to 0.4°C of avoided warming by the end of this century just by phasing out hydrofluorocarbons. Simultaneously improving the energy efficiency of cooling equipment could double the benefits. According to a study by the Lawrence Berkley National Laboratory, such energy efficiency improvements can benefit India. If the average room air conditioner efficiency improves by six per cent per year, more than 64 TWh per year of energy could be saved by 2030. This would cut greenhouse gas emissions, protect cities’ power infrastructure from overload, and bring cumulative consumer benefits of up to US$25 billion.

Prioritizing new cooling solutions

The plan doesn’t just look at efficiency. It prioritizes other solutions, such as passive cooling, building design, fans and coolers, new technologies and behavioural change. Among the new technologies is district cooling—the distribution of cooling energy from a central plant to multiple buildings.

The Ministry of Environment, Forests and Climate Change is co-chair of the UN Environment-led District Energy in Cities Initiative, which is working with three pilot cities—Amaravati, Rajkot and Thane – in India to demonstrate these technologies. Three quarters of the buildings required for 2030 have yet to be built, so there is a huge opportunity for new urban developments to use district cooling, which can be up to 50 per cent more efficient than stand-alone solutions.

“UN Environment praises India’s leadership in being the first country to adopt a comprehensive plan for the cooling sector,” says Atul Bagai, Head of UN Environment’s India Country Office. “Singling cooling out is vital to scaling up and targeting action on what has for years been a silently growing environmental catastrophe, and India’s Cooling Action Plan should set the benchmark for other countries to follow. UN Environment stands ready to support India to achieve and surpass its targets.”

Last month, UN Environment, the Climate and Clean Air Coalition, the Kigali Cooling Efficiency Program, and Sustainable Energy for All launched the Cool Coalition. The coalition is a unified front that links action across the Kigali Amendment, Paris Agreement and Sustainable Development Goals. It will inspire ambition, identify solutions and mobilize action to accelerate progress towards clean and efficient cooling.

These kinds of actions provide hope that we can help keep everyone, and the planet, cool.

Just One-Third of the World’s Longest Rivers Remain Free-Flowing

MD Staff

Published

on

Just over one-third (37%) of the world’s 246 longest rivers remain free-flowing, according to a new study published in the scientific journal Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe.

A team of 34 international researchers from McGill University, World Wildlife Fund (WWF), and other institutions [1] assessed the connectivity status of 12 million kilometers (~7.5 million miles) of rivers worldwide, providing the first ever global assessment of the location and extent of the planet’s remaining free-flowing rivers. [2]

Among other findings, the researchers determined only 21 of the world’s 91 rivers longer than 1,000 km (~600 miles) that originally flowed to the ocean still retain a direct connection from source to sea. The planet’s remaining free-flowing rivers are largely restricted to remote regions of the Arctic, the Amazon Basin, and the Congo Basin.

“The world’s rivers form an intricate network with vital links to land, groundwater, and the atmosphere,’’ said lead author Günther Grill of McGill’s Department of Geography. ‘’Free-flowing rivers are important for humans and the environment alike, yet economic development around the world is making them increasingly rare. Using satellite imagery and other data, our study examines the extent of these rivers in more detail than ever before.”

Dams and reservoirs are the leading contributors to connectivity loss in global rivers. The study estimates there are around 60,000 large dams worldwide, and more than 3,700 hydropower dams are currently planned or under construction. They are often planned and built at the individual project level, making it difficult to assess their real impacts across an entire basin or region.

“Rivers are the lifeblood of our planet,” said Michele Thieme, lead freshwater scientist at WWF and global leader of WWF’s free-flowing rivers initiative. “They provide diverse benefits that are often overlooked and undervalued. This first-ever map of the world’s remaining free-flowing rivers will help decision makers prioritize and protect the full value rivers give to people and nature.”

Healthy rivers support freshwater fish stocks that improve food security for hundreds of millions of people, deliver sediment that keeps deltas above rising seas, mitigate the impact of extreme floods and droughts, prevent loss of infrastructure and fields to erosion, and support a wealth of biodiversity. Disrupting rivers’ connectivity often diminishes or even eliminates these critical ecosystem services.

Protecting remaining free-flowing rivers is also crucial to saving biodiversity in freshwater systems. Recent analysis of 16,704 populations of wildlife globally showed that populations of freshwater species experienced the most pronounced decline of all vertebrates over the past half-century, falling on average 83 percent since 1970.

The study also notes that climate change will further threaten the health of rivers worldwide. Rising temperatures are already impacting flow patterns, water quality, and biodiversity. Meanwhile, as countries around the world shift to low-carbon economies, hydropower planning and development is accelerating, adding urgency to the need to develop energy systems that minimize overall environmental and social impact.

“Renewable energy is like a recipe – you have to find the right mix of ingredients to have both a sustainable energy grid and a thriving natural world,” said Thieme. “While hydropower inevitably has a role to play in the renewable energy landscape, well-planned wind and solar energy can be more viable options for rivers and the communities, cities, and biodiversity that rely on them.”

The international community is committed to protect and restore rivers under Agenda 2030 for Sustainable Development, which requires countries to track the extent and condition of water-related ecosystems. This study delivers methods and data necessary for countries to maintain and restore free-flowing rivers around the world.
