Reuse of the dredged sediments

The setting sun paints the sky and sea in red and orange. Tiny pieces of broken seashells glitter in the vast sandy beach.  This is the location of the Putou Operation Area of the Meizhou Bay Port. This 1,200-square-meters land has been filled with dredged sediments from the Meizhou Bay Navigation Improvement Project, and six berths for ships will be built here.

Supported by a $50 million loan from the World Bank, the project seeks to widen and deepen 21.5 kilometers of the existing main channel through dredging and rock blasting. Managing the disposal of large amounts of dredged sediments and debris was a challenge.

“The traditional way is to dump it into the ocean.  But it would cause pollution of the ocean. So we used the dredged sediments to backfill the land area behind the port, and turned the waste into something useful,” said Chen Jianxin, a division chief from the project management office.

Reusing the dredged sediments, estimated at 16 million cubic meters, could save up to RMB100 million ($15 million), said Zhao Xiangchao, manager of the Putou Operation Area.

Mitigating the environmental impact

The dredging of the navigation channel has major environmental impacts on bottom-dwelling organisms such as worms, clams, crabs and lobsters, and aquatic habitats, coastal mudflats, water quality and marine hydrodynamics. In addition to mitigation measures, an ecological compensation plan has been carefully designed, which includes a fish reproduction and release program, and a habitats restoration program for planting mangroves.

In the fish reproduction and release program, five fast-growing native fish and shrimp species with high economic value have been selected and bred in a hatchery under the supervision of the Fujian Fisheries Research Institute. These are released in batches during a five-year period.

The fourth release event took place on August 11, 2017 on the coast of Quanzhou. A researcher from the fishery institute conducted a sample count of the tiny shrimps brought in from the hatchery before these were loaded onto fishing boats and released into the sea.  About 150 million baby shrimps was released that day, and researchers will monitor and carry out follow-up surveys to assess the effects of the program later.

The program is welcomed by the local fishing communities. An increase in fishery resources leads to more catches and therefore more income. A fisherwoman who joined the release work said there are now more fishes than before.

The 950-year-old Luoyang Bridge in Quanzhou is the first stone bay bridge built in China, and is one of the country’s four most famous ancient bridges. Near the bridge are large areas of lush green mangroves.  A few egrets can be seen resting or searching for food among the trees. These mangroves are part of the Quanzhou Bay Estuary Wetland Nature Reserve.

“Under the project, we have planted 558 mu (372,000 square meters) of mangroves inside our reserve,” said Lai Xingkai, an engineer from the reserve.

Mangroves play an important role in coastal protection.  Lai listed their three major benefits: they can improve water quality, reduce pollution and eutrophication (over-enrichment of water by nutrients), and prevent red tides; they can reduce waves and strengthen dikes; and they provide a home to birds and coastal animals.

“Our workers are all hired from the nearby villages, and familiar with local conditions. We have more than 40 regular workers to maintain the mangroves,” Lai said.

Chen Chunfang, a local resident in the Zeng’an Village, looks after the mangroves as a part-time job. Every day, she would drive around the mangroves and stop any activity that may be harmful to the trees.  “With the mangroves, the environment has become so much better, and there are so many birds now, particularly in the morning,” said Chen.

Close attention has been paid to the protection of the environment during the project’s implementation, with more than RMB30 million ($4.55 million) invested in environmental measures. Engineering design was optimized to reduce the disposal area; special staff were assigned to supervise environmental compliance of contractors; related training courses were organized; intensive environmental quality and impact monitoring was conducted; and independent environmental consultants were engaged to assess the implementation of the environmental management plans and provide technical guidance and support.

Improving connectivity and creating jobs

Located between Quanzhou and Putian in the middle of the coast of Fujian Province, the Meizhou Bay Port is a major bulk port, handling approximately 40 million tons of freight in 2010 at 46 berths spread over four port areas. The main commodities handled are crude oil, building materials, coal and oil products, as well as iron ore, grain, and timber. It is also the closest port to some of the inland provinces.

Upon completion of the project in 2019, the main navigation channel will be upgraded to a 300,000 DWT (deadweight tonnage) standard that will allow for unidirectional tide-independent navigation of Q-MAX LNG (liquefied natural gas) ships, as well as unidirectional tide-dependent navigation of bulk cargo ships up to 400,000 DWT, the world’s largest bulk vessels.

The development of the Meizhou Bay Port will reduce the land transport distance and improve transport connectivity between the land-locked provinces of western Fujian, Jiangxi and Hunan and the ports and cities of the more dynamic coastal region, thus boosting the growth of the underdeveloped inland regions.

Domestic and international shipping companies, as well as the nearby industries that are heavy users of the port such as petrochemicals, power generation, timber processing and grain milling will directly benefit from improved navigation conditions.

Sinochem Quanzhou Petrochemical Co. operates five berths for import and export of crude oil and petroleum products.  Zhang Huaiguo, a manager from the company’s storage and transportation department, expects the project to reduce ships’ waiting time outside the port.

CNOOC Fujian LNG Co runs an LNG (liquefied natural gas) port. The current capacity of the navigation channel only allows 66,000 cubic meter LNG tankers. “Growing demand for LNG in the domestic market requires larger tankers, for example, 217,000 cubic meter Q-Flex tankers. Larger tankers would reduce transportation costs substantially,” said Xu Guoyang, a manager of the company’s production and operation department.

Xu’s words were also echoed by Yang Jin, a deputy engineering manager of the Luoyu Port, a large iron ore port under construction. “Ships of the future will be larger, because larger ships are more environment-friendly and cost-effective,” said Yang.

The port and associated industries have employed more than 30,000 people, with additional jobs provided by the upstream and downstream industries spawned by petrochemical and energy industries, benefiting the local communities.

Sharing knowledge and strengthening capacities

“The involvement of the World Bank has brought us international experience and best practices,” said Yu Junqi, a deputy director of the project management office. “The project has provided opportunities for knowledge sharing with peers in and outside China, by organizing study tours to major international ports such as Hamburg, Rotterdam and Esbjerg, and inviting experts from Germany and Singapore to give training and technical assistance. This has helped strengthen the capacities of the port authority,” he said.

Contributing to the Belt and Road Initiative

By 2020, the Meizhou Bay Port is expected to increase the number of productive berths from 50 to 90 with handling capacity reaching 200 million tons, and have the channel capacity for the world’s largest bulk carriers to enter. The port authority is also developing several logistics parks and a bulk goods trading platform, and seeking partnerships with other domestic and international sea ports, committed to play a greater role for the implementation of the Belt and Road Initiative, according to its director Li Qing.

Climate Smart Agriculture Can Help Balochistan bounce back

Climate change brings disaster to the province Balochistan, which is an arid region located in west of Pakistan. The drought-stricken region struggling to increase its agricultural productivity, faced a backlash due to catastrophic floods. The predominantly agriculture-based territory reached the dead zone as farmers had stopped farming, shepherds kept their animal numbers low, which put people’s lives on stake, as it increased food insecurity. This highlighted the need to start a policy debate for climate smart agriculture.

Climate smart agriculture is an approach that is making the planet prosperous again. It is an ambition to increase the integration of food security with enhance resilience in productivity. It is a sustainable agriculture practice that promotes soil health, water management, and biodiversity conservation with economic benefits. Its practices like, cover/tunnel farming, drip irrigation, crop livestock systems can help Balochistan to go green and integrated again. These practices can sequester carbon in soil and can fight the impacts of climate change more efficiently.

Climate change is affecting the province in various ways. The region of Balochistan is characterized by extreme aridity, with annual precipitation levels below average, causing severe droughts, which is leading to a catastrophic impact on the province’s agriculture and livestock.

Flash floods in Balochistan becomes the new common during the monsoon season as a result of heavy rainfall, with the most significant in 2022. These floods have a detrimental impact on the environment, causing soil erosion, depletion, and the loss of fertile topsoil. The soil is already deficient in minerals and cannot endure further depletion, requiring several hundred years to recover and cannot support agricultural growth.

In an interview with wealthPk, Dr. Hanif-ur-Rehman AP from university of Turbat said, that high efficiency irrigation system (HEIS) can play an efficient role in climate effected regions like Turbat, Makran, Kech where farmers had traditionally cultivated the crops for source of income. The use of drip, rain guns, Centre pivot, and sprinkler have the ability to bring back the lush green pastures that have turned barren.

Climate smart agriculture could not only fetch the lost agriculture but also increase the productivity rate by making the rest of the region green. Balochistan accounts for only 6% of cultivable land for agriculture which not only failed to meet food security needs but also added little in Pakistan’s 25% agriculture GDP.

Balochistan people despite having less literacy are very conducive to cultivating lands with new cultivation techniques. In late 1990s and 2000s when the entire western part of the province was severely hit by droughts, people brought the techniques of less resilient tunnel farming to moist the soil. They grow crops beneath protective plastic tunnels. This technique helps them cope with their immediate needs but it fails to produce yield on a massive scale. Cultivation in proper climate resilient tunnels usually requires 10 to 20 acres of area or economically 3 acres feasible, and the tunnels are created by using steel pipes, or aluminum pipes that support plantations that are usually 3 to 12 feet in height and 5-10 feet wide. 

 The drip irrigation technique also has enormous potential for minimizing production costs by moderating the input use of water, fertilizers and pesticides. Drip irrigation keeps the field capacity constant by enabling the crops to easily take in water and nutrients, which result in uniform growth of plants and enhances the quality that produces well.  Drip irrigation distributes water through a network of valves, pipes, emitters, and tubing that can save 50-70% of irrigation water which can not only resolve the water scarcity issue of Balochistan, it also can produce efficient, extensive production of crops such as apples, cherries, tomatoes, and citrus.

The province also needs to move towards an integrated crop-livestock system (ICLS), which is sustainable, productive, and climate resilient compared to intensive specialized systems. ICLS have increased over time in arid regions but still, Balochistan lags behind due to lack of skills by producers, lack of investment, lack of sustainable awareness and market competition. Livestock production is the largest sector of the province’s economy. It is nearly impossible to have a dream of economic development for the rural masses without prior attention to Livestock and crop management.

After floods, the crops fields are destroyed due to which livestock become the main source of food for many rural households that make the rural farming through livestock less practicable.  It can only be enhanced by administration policies through capital funding, educational services and markets to subsistence farmers.

CSA is a method that includes several elements entrenched in local settings rather than a collection of practices that can be used everywhere. CSA requires the adoption of technologies and policies, and it refers to behaviors both on and off the farm.

According to FAO (Food and Agriculture Organization) of the United Nation 2023 report, Local farmers are the foremost holders of knowledge about their environment, agro-ecosystems, crops, livestock, and climatic patterns. Therefore, the adoption of Climate Smart Agriculture should be aligned with the local farmers’ knowledge, needs, and priorities. . Farmers of Balochistan have shown a keen interest in drip irrigation, tunnel farming technique but the high cost of imported pipes, emitters, plantation of aluminum tunnels from china has become their hindrance.

Mainstreaming CSA in Balochistan requires critical stocktaking and promising practices by financial and institutional enablers that can create an initial baseline for discussion and investment from the globe. If the government of Balochistan supports the farmers through public funding or by joint ventures with farmers for covering the startup costs, the techniques can be very useful not for food security but also for economic benefits on a constant level. According to a report on Climate smart practices, the CS techniques could not only help to save water up to 50-70%, reduce the fertilizer use by 45%, increase yield up to 100-150%, reduce the production cost by 35%, but could also mature the crops with better quality for uneven topography.

Human History and the Wonder of the Horse

Imagine a person accustomed to traveling at 3 to 4 mph, who discovers a means (the horse) to speed up to 5 times that pace with occasional thrilling bursts doubling even that.

At 15 mph, it is then not unreasonable to assume a 1000 mile range for a week on horseback allowing for breaks and sleep at night.  It must have expanded enormously the horizons of those early Kazakhs who first domesticated the horse some 6000 years ago.

If the Kazakhs roamed west, the Mongols, a few thousand years later, roamed back and began a vast empire that eventually included all of China.  Ties with Russia were close but as a hegemon, until a few centuries later when the Russians threw off the yoke. 

As Vladimir Putin and Xi Jinping shake hands forging a new treaty, China is once again a more powerful economy, the largest in the world, while Russia’s is more akin in size to Italy’s.

If the horse made the vast Central Asian steppes explorable, its remarkable navigational skills ensured the rider would eventually be able to return home.

Apparently horses are sensitive to the earth’s magnetic field, and not unlike homing pigeons can find their way home.  Confirmatory tests have shown that when magnets are slung over their withers, they get completely lost.  Observers have also noted that, in pasture. they tend to stand north-south aligned with the earth’s magnetic field.

Up until the advent of the internal combustion engine, horses were used for all kinds of transportation.  Where the rail line ended, horses took over.  They  hauled freight in covered wagons; pulled stagecoaches in the Wild West and elegant carriages in Europe; they were a cowboy’s bread and butter, and personal transportation for anyone who could afford one; horses in the cavalry delivered the punch generals were seeking in battle; in racing, they provided thrills for the audience and excitement for punters — such is true also today, and with all the special attention given to the triple crown races, the casual observer might forget the weekly calendar of racing events across the country.

Horses for courses is a common saying for they are bred for speed in short races and stamina for long steeplechases like the famous Grand National in England.

Hark back to the wagon drivers of old, when on lonely long journeys the driver could talk to his horses — like dogs they are able to understand and develop quite a vocabulary of human words plus silent signals from the reins and legs of the riders.

And pity the poor trucker now and his lonely cross-country trips —  not much to say to a noisy diesel engine!  The only chance to talk he gets is when he takes a break to eat, rest and sometimes sleep at truck stops along the way.

With all that horses did for humans, one can wonder what they got out of it.  Apparently they form close bonds with their owners, and as with dogs, the feelings are mutual.

Race to zero in Asia and the Pacific: Our hopes in the climate fight

Published

The latest synthesis report from the Intergovernmental Panel on Climate Change makes for grim reading: Every fraction of a degree of warming comes with escalated threats, from deadly heatwaves to severe hurricanes and droughts, affecting all economies and communities. It is a reality that the people of Asia and the Pacific know only too well. “The worst April heatwaves in Asian history” last month was just a taste of the worsening climate impacts we will continue to face in the years to come.

Our latest report highlights that the sea level is creeping up in parts of the region at a slightly higher rate than the global mean, leaving low-lying atolls at existential threat. Annual socioeconomic loss due to climate change is mounting and likely to double in the worst-case climate scenario. Inequity is yet another threat as climate change sweeps across the region. Asia and the Pacific already accounts for more than half of global greenhouse gas emissions and the share is growing. 

But there is another picture of hope in our region: 39 countries have committed to carbon neutrality and net zero between 2050 and 2060. The cost of renewable energy is falling almost everywhere, with installed capacity growing more than three-fold in the past decade. Electric vehicles are entering the market en masse as countries such as China, India, Japan, the Republic of Korea and Thailand have made electric mobility a priority.

This momentum needs to accelerate like a bullet train. Because nothing short of a breakthrough in hard-to-abate sectors will give us a good chance of stopping catastrophic global warming.

Accelerating a just and inclusive energy transition

The recent energy crisis has kicked renewable energy into a new phase of even faster growth thanks to its energy security benefits. There is opportunity now to leverage this momentum and turn it into a revolutionary moment.

Cross-border electricity grids can be the game changer. ESCAP has simulated different scenarios for grid connectivity and scaling up renewables. It shows that a green power corridor, cross-border power grid integration utilizing renewables, can help to remove the last hurdles of the transition. We are working with countries to chart a path to improved regional power grid connectivity through cooperation.

Achieving low-carbon mobility and logistics

The exceptional growth of electric vehicles has proved that electric mobility is a smart investment. And it is one that will help stave off carbon dioxide emissions from transport, which has stubbornly increased almost by 2 per cent annually the past two decades.

Through the Regional Cooperation Mechanism on Low Carbon Transport, we are working with the public and private sector to lock in the changeover to low-carbon mobility, clean energy technologies and logistics. This is complemented by peer learning and experience sharing under the Asia-Pacific Initiative on Electric Mobility to accelerate the penetration of electric vehicles and upgrading public transport fleets.

Building low-carbon industries through climate-smart trade and investment

The net zero transition is not complete without decarbonizing the industrial sector. The region accounts for nearly three quarters of global greenhouse gas emissions in manufacturing and construction.

Binding climate considerations in regional trade agreements can be a powerful tool. While climate-related provisions have entered regional trade agreements involving Asian and Pacific economies, they offer few concrete and binding commitments. To unlock further benefits, they will need to be broader in scope, deeper in stringency and more precise in obligations.

As foreign investment goes green, it should also go where it is needed the most. It has not been the case for any of the least developed countries and small island developing States in the region.

Financing the transition

The transition can be only possible by investing in low- and zero-emission technologies and industries. Current domestic and international financial flows fall well short of the needed amount. The issuance of green, social and sustainability bonds is rapidly growing, reaching $210 billion in 2021 but were dominated by developed and a few developing countries. Both public and private financial institutions need to be incentivized to invest in new green technologies and make the uptake of such technologies less risky.

Linking actions and elevating ambitions

The code red to go green is ever so clear. Every government needs to raise their stake in this crisis. Every business needs to transform. Every individual needs to act. A journey to net zero should accelerate with a fresh look at our shared purpose.

At ESCAP, we are working to bring together the pieces and build the missing links at the regional level to support the net-zero transition work at the national level. The upcoming Commission session will bring countries together for the first time in an intergovernmental setting – to identify common accelerators for climate action and to chart a more ambitious pathway. This is the start of an arduous journey that requires cooperation, understanding and determination. And I believe we have what it takes to get there together.
