Xie et al rehabilitating a degraded watershed

  1. 1. Rehabilitatinga DegradedWatershedA Case Study from China’s Loess PlateauLearning series on sustainable water and land management
  2. 2. 2 ForwardT he Loess Plateau Case Study describes the transformation of a large area of degraded watershed in China. It is largely based on the two Loess Plateau Watershed Rehabilitation Projects, funded by the Chinese Government and The World Bank and implemented from 1994-2005. The two projects restored a vast area of degraded watershed and improvedthe wellbeing of millions of rural households, the majority of whom lived in poverty prior to the projects.Told as a story, the case allows the reader to easily absorb key lessons about watershed restoration that can be applied inother parts of the world. Viewed through the eyes of a farmer who returns to his hometown after a long absence, thecase study begins by describing the changes in a poor rural county that have taken place during the decade of projectimplementation. Farmer Zhang is shocked to see a verdant, tree-filled landscape has replaced the brown barren hills of hisyouth and that his family members and their fellow villagers have escaped poverty and are engaged in a variety of profitableand sustainable ventures.The study continues by analyzing how the project interventions broke the vicious cycle of environmental degradation andunsustainable farming practices and helped catalyze a virtuous cycle that has restored the watershed and enriched the livesof its inhabitants. It outlines the challenges facing Chinese project director, Huang Ziqiang, and World Bank task teamleader, Juergen Voegele, in designing an effective project and systematically describes the steps taken to transform theenvironment. The study is divided into three parts: Part A, “Living on a Moonscape” describes the project area before theproject begins; Part B, “The Transformation” gives the reader a glimpse of the changes that have taken place; and Part C,“Seeking Solutions under a New Approach” explains the key elements that enabled the transformation in detail.The case study uses the Harvard University Case Method pedagogy, and pilots its use in teaching the management of naturalresources. A teaching note is available for those wishing to teach in a face-to-face setting. Teaching is enhanced by a seriesof film clips edited by the WBI team from movies produced by Environmental Education Media Project, which filmed changesover the life of the Loess Plateau projects. The case study and supporting materials will be made available online by WBI.The case study is a module of a learning program from the Climate Change Unit at the World Bank Institute (WBI). Theobjective of the program is to improve the capacity of client countries to improve land-water management and cope withclimate change. The Loess Plateau case illustrates the link between land and water management, soil-water conservationand livelihoods in watershed management. It is particularly helpful in demonstrating the necessity of addressing foodsecurity and poverty reduction hand-in-hand with ecosystem restoration. -The Case Study Team
  3. 3. Part A: Living on a Moonscape 3S adly, Zhang Junyou bid farewell to his family and began the day-long trek to the town where he could catch the long-distance bus to the city. There, he would join millions of other migrants seeking work. Asthe oldest child, he had made the painful decision to leavethe land his family had farmed for generations, so he couldearn money to send home and give his parents and siblingsa better life. Finding ways to put food on the table was anever-increasing worry for the family. It was 1990 and whilemost of China was transforming, and land reform was greatly Loess Plateau (within red), Chinalifting productivity, these changes had scarcely touched theland where Zhang lived.Zhang was born in a small village in the hills of Ansai County,Shaanxi Province, on China’s vast, desolate Loess Plateau, drought squashed any hope of planting more lucrative crops.where 50 million people struggled to survive on one of the There were no surplus goods to sell, and with dirt-track roadsmost degraded ecosystems on earth. For many, dwellings almost impassable in winter and in time of floods, the villagewere simply candle-lit caves. Typical of households on the was isolated from any possible market.Plateau, Zhang’s family lived below the poverty line, earningless than US$75 a year. All their time and energy was taken China’s Loess Plateau covers four provinces (640,000 squareup in the struggle to feed the family with what they could km), an area bigger than Kenya. It was created two milliongrow on eroded hillside slopes, some so steep they could years ago by the deposition of wind-blown dust and bybarely stand up. Each year the family had to rely on relief glacial till, called loess, which was left behind by retreatinggrain to supplement their meager harvest of drought-hardy glaciers. Loess is good agricultural soil but prone to windmillet, buckwheat and beans. To find grazing for their goats, and water erosion, which has carved deep gullies into thethey had to go further and further afield. Year after year of Plateau, transforming it into a maze of sub-watersheds. For thousands of years, the ancestors of farmers like Zhang had felled trees so they could plant crops on steep slopes, and their sheep and goats had grazed the vegetation bare. As a result, what little rain fell in the wet season ran straight into the gullies, taking fertile topsoil away with it. With no protection from the wind, dust storms whipped across the seemingly uninhabitable moonscape, depositing a dirty yellow film on buildings as far away as Beijing, some 500 km away. Up to four billion tons of soil, sand and mud ran off the Plateau each year, having a disastrous effect on the downstream reaches of the world’s sixth largest river - the Yellow River.Cave-dwelling
  4. 4. 4 Degraded land upstream, disaster flows downstream Until it cuts through the Loess Plateau, the almost 5,000 kilometer long Mother River—the Cradle of Chinese Civilization—runs clear. Downstream, it is the most sediment-laden river in the world, prompting the evocative name “Yellow River”. The river has over the years become a ‘suspended river’ – as in its lower reaches the riverbed is some 2 meters above the surrounding lands. Dikes have continuously been made higher to keep up with the rising riverbed, and breaches in the dikes have led to some of the world’s worst floods. It was clear thatSevere soil erosion something would have to be done about the sediment entering the river from the Loess Plateau, but this was easier said than done. Huang Ziqiang often lay awake at night worrying about how things might be changed. He was the director of the Bureau for Water and Soil Conservation, of the Yellow River Conservancy Commission, which falls under the Ministry of Water Resources. His Bureau was responsible for soil and water conservation; agriculture, forestry and livestock fell under other ministries. Huang was a well- respected water conservation manager, and an engineer by training. For twenty years, he had led the challenging taskSheep grazing on slopes of promoting soil conservation on the Loess Plateau. His offices employed hundreds of China’s best engineers and soil scientists. But, despite their technical competence and relentless effort, the problems of the Loess Plateau were only increasing. As the population expanded, unsustainable farming practices led to ever-worsening ecological degradation. Millions of dollars had been spent by various ministries and departments, but the efforts were not well coordinated and often worked at cross-purposes. To develop livestock, sheep and goats were distributed to farmers, but they ate the seedling trees provided by reforestation programs,Life on the barren land and further aggravated soil erosion. As the degraded land

Besides, any investment inhigher on the slopes and graze more livestock on the slopes trees was likely to disappear into the stomachs of the manyto avert hunger. This added to the problems Huang’s programs village goats.had been trying to address. Zhang also remembered other campaigns to reduce the“The Government has tried just about everything: campaigns erosion and increase farmland.

But, evenand create flat land in gullies,” Huang reflected. “Literally if anyone could afford a tractor, the narrow, hand-dug terracesevery village had received funds at some point. But with could only be worked by ox and plough. They crumbled easilypopulation pressure, continued unsustainable practices, and in heavy rain and repairing them took much labor, effectivelysuch a large area to cover, these small investments were like wiping out any gain.

Although farmer Zhang did not know it, in 1990 the ChineseAs various ideas were tried and failed, farmers like Zhang had government was preparing a new project, which would finallybecome cynical. As the bus took him further from home, he bring lasting change to the Loess Plateau. The motivation wasrecalled how village leaders had organized a yearly campaign another project – a proposed US$5 billion dam to provide floodto “green the Loess Plateau.” For weeks, the villagers hiked protection for people living downstream of the Loess Plateau.up the hills to plant tree seedlings and grass.

Despite various campaigns urging them to care for comprehensive solution to the degraded watershed, workingthe trees, most villagers ignored any that survived.

  6. 6. 6the moonscape could become green and fertile. “Someone,somewhere must have tried something that worked”, theythought.But as they surveyed yet another barren and eroded watershed,and listened to more villagers recount their futile efforts toescape poverty, the enormity of their challenge was clear.“The Loess Plateau is the hardest bone to chew,” said Huang.“The region is far behind the rest of the country.”Still, Huang knew that flat agricultural land in nearby areascould yield 10 tons of wheat per hectare, ten times as muchas was produced on the steep slope land. The Loess soil hadthe potential to produce good crops, as long as water could be Cultivation on slopesretained instead of running off.Both Huang and Voegele were deeply moved by the stories him if he would like to expand his operation on the plateauthey heard.

Arriving occasions in the past in the county center, Zhang was amazed to find he could now take a bus to his village. Instead of the dirt His parents had aged visibly, but this could not hide their track he remembered, there was a wide, gravel-paved road. enthusiasm for the changes that had occurred in their lives. The view from the bus window was unrecognizable – maybe Yields on their new terraces were double and sometimes he had boarded the wrong bus! The land had turned green triple what they had enjoyed in the past. Farming was easier for as far as the eye could see. The once-brown hills were now. Because they used tractors to plow their terraces, the now a forest of pines and bushes, and the formerly eroded family had time and resources to cultivate small groves of gullies were covered with hardy shrubs and grass. The old apple and pear trees. slope land was now covered with neat green terraces, where wheat, corn and potatoes grew in abundance. It was odd to Zhang’s younger brother, now married with his own family, see no signs of drought – had the weather patterns changed was enthusiastic about his new sheep and cattle-breeding during his absence? Even in the best of years the land used venture. One of his older uncles joined the party. He to be parched and the crops he remembered were always complained loudly that the mutton served at dinner was not starved for moisture. He spotted apple trees and other trees as tasty as meat in the old days, when the sheep grazed freely. he did not recognize on some of the terraces and on the hills, But even he reluctantly admitted that the sheep and cattle but there was no sign of the goats that he used to see on the cared for by his son were very profitable.

What had seemed impossible in 1990 was now delivering even more than had been hoped for when planning for the projects began. Zhang was proud of his family and village for bringing about this change, and peppered them with questions to find out how they had done it, while his mind raced with plans for his own future. One thing was certain - he no longer needed to plan for a long bus ride back to the construction job in the distant city.Land covered with terraces After projects - gullies covered with trees, hardy shrubs and grasses
  8. 8. 8 Part C: Seeking Solutions under a New Approach I n the two years it took to prepare the Loess Plateau watershed rehabilitation project, the team led by Huang Ziqiang from the Upper- Middle Reaches Bureau of the Yellow River Commission and the team led by Juergen Voegele from the World Bank worked closely together and visited all four provinces and numerous villages on the Plateau. Searching for solutions, they travelled through some of China’s poorest counties. Listening to farmers lament their difficulties putting food on the table drove home the point that the Government and the Bank must focus as much on improving farmer livelihoods as they do on solving the problems of ecological degradation. At an old school house in Xiaochen Village in Pingliang Prefecture, ShaanxiTravel on new roads to market Province, one village elder asked why they should keep trying to plant trees. “People can’t eat trees!” he shouted. Others agreed. “I have no time to spend on anything but the land!” exclaimed another. Asked whose families were forced to rely on Government relief grain supplies, most of the hands in the room shot up. “I work all day long in the field but the grain produced is only enough for half a year,” said a mother, “When it rains the earth comes loose and washes away. My land becomes smaller each year.”  Another woman added, “We keep some goats for cash, but they don’t sell well. There’s less and less grass here.” Voegele was puzzled when farmers said they had tried many times to build terraces to create flat land, but the terraces did not hold up well and were often more trouble than they were worth. He made a mental note to investigate the terracing issue further.Fruit orchards on slope land Small successes show the way The teams of Voegele and Huang spent considerable time listening to the farmers. Despite the pessimistic tone of many of their meetings, there was some good news. In a small number of sub-watersheds around the Plateau, the Government had started experimenting with integrated watershed planning. These pilot programs seemed to be boosting farmer incomes. Wider terraces had been created to increase agricultural land. Orchards were planted on the less steep slopes; and shrubs and grasses on the steepest areas. Farmers seemed pleased with the higher grain yields and optimistic about their orchard trees. New housing with solar dishes for cooking. Concrete paved yard collects rainwater for domestic use

It was a new approach. Wide terraces Wide terraces
  10. 10. 10Huang often compared the Loess Plateau dilemma to a giantperson who had suffered a long illness. “Our past efforts focusedon curing the symptoms (soil erosion, loss of water and surfaceflows), without paying enough attention to the fundamentalcause of the disease (poverty, low productivity, and the viciouscycle).”Breaking the vicious cycle: Wider terraces triple food yieldJuergen Voegele was adamant. “We must give something to Small dams together with terracesthe people right from the start. Farmer benefits first andthen the environment. Improved grain yields are absolutelycritical.” Because food security was utmost in farmers’ Returning to the project area one year after its start, Huangminds, there was little point in discussing any other aspects and Voegele were elated with the results: “With a minimumof integrated watershed management, until farmers could be of 2 mu of terraced land per person, a family can growassured of significant increases in grain yields.

These reformsreturns! However, he also knew that building terraces alone took longer to reach remote regions like the Loess Plateau. Ascould not solve the environmental problems that kept him Voegele had discovered in his first visits to plan the project,up at night. most Plateau farmers did not yet have secure long-term land-use leases, although many party leaders and provincial officials thought that they did.Breaking the vicious cycle: Integrated planning andincentives Voegele and his team made it clear that secure land tenure was a “life or death matter” for the project. “If we are goingTerracing was only part of an integrated watershed plan to finance building sustainable terraces in the Loess Plateauthat was designed to rehabilitate the ecosystem AND to give with public funds,” asserted Voegele, “the farmers need tofarmers the incentive to contribute to the solution.

Scattered slope plots were consolidated condition could be met. Farmers were given long-term leasesinto larger terraced plots, built on land that ideally sloped to the improved terraces, slope land for tree cultivation, andless than 15 degrees. The principle was that every family areas behind the warping dams.would get at least 2 mu of arable land per person. Plotswere publicly measured to ensure transparency. Valuableflat agricultural land was also created by small warping damsbuilt in the gullies to trap sediment.Because they now had higher-yielding land, farmers wereencouraged to give up cultivating the steeper slopes, sothat soil-retaining shrubs, and trees of economic value couldbe planted. This was a critical link, aligning the farmers’financial benefits and the project’s ecological benefits. Tree planting
  12. 12. 12 Once local people “owned” their project, this would change, Huang believed. While contracts and commitments were important, and required by the Bank, it was crucial that people saw how they could benefit from their involvement and input to the project. Only when officials at all levels understood the project belonged to them, could it be a success. Such ownership would only come about through local participation. “We realized that this project belonged to us - the Chinese people. If farmers do not receive the maximum benefit, how can we justify the huge project costs, and repay the foreign loan? We must get the project right,” Huang repeatedly reminded his team. Getting it right involved a great deal of time, as well as theApple orchard - medium term gains involvement of millions of villagers, working on watershed projects with thousands of multi-disciplinary project teams, with the co-operation of a wide range of different agencies –This was formally documented in a little red booklet which but always with a local focus.detailed the size and co-ordinates of each land use lease,and was signed by the farmer and stamped by the local Project officials had to work intensively in each village, toauthorities. craft a sub-watershed plan that met local conditions.

Sometimes this meant traditional practices used by the soilIn return, every farmer, even the poor, was committed to and water conservation bureaus needed to change. Otherrepaying the public investment that had been made to benefit times, it meant convincing the Bank team to adapt theirtheir private interest through the Loess Plateau Watershed requirements to local conditions. At one memorable meeting,Rehabilitation Project. The terms for repayment varied: Huang convinced Voegele that Bank procedures needed tofor activities that yielded a quick profit, such as terraces, adjust so that Chinese counterpart funds could be accessed in an innovative manner –by pulling funds from differentloans were repaid in 2-3 years, while longer terms applied projects together under the comprehensive watershed plans,to investments in trees and shrubs. Repayment terms were and the Bank team accepted.softer in areas prone to severe drought. As local ownership became a reality, trust also developed.

As those farmers gained confidencecould proceed faster without the bother of detailed planning in the higher yields from their new terraces, slope cultivationand contracting, and resisted some of the project conditions. gradually stopped.
  13. 13. 13Creating a virtuous cycle: longer term investmentWith the labor savings from the terraces, and their families well-fed withinone or two seasons, farmers had more time and resources, and could considermedium and even long-term investments such as the planting and care of treesof economic value.When farmers provided labor, the project provided free trees and shrubs butrequired that farmers sign “Use and Management” contracts. These began oncethe trees were well-established. The project experimented with contractingterms, as well as tree varieties and planting techniques to optimize survivalrates and profitability in the long-term. China’s forestry experts introduced Pen feeding - sheepinnovative methods and gave technical advice, while young villagers weretrained in nursery and planting techniques.Gao Shenggui of Xinmaotai village had three ha of low-yield agricultural land.With support from a project technician, he took out a loan to plant 3 ha of appletrees, which thrived and began to yield within three years. By 2005, buyers ofhis apples were coming from all over China, he had 10 seasonal employees andhis annual income had risen to $15,000. Bai Xin Nian, of Bai Dong village, useda project loan to plant apple trees on what had been his wheat and maize fields.Within three years, his profit per hectare had increased 10-fold, and he usedthis income to build himself a new house. Creating a virtuous cycle: The grazing ban Pen feeding –profitable new speciesNo amount of technical help could guarantee that trees would survive as long asgoats, which ate everything in sight and ripped out the roots of the plants theyconsumed, were still grazing in the areas.The project could only really see results when grazing was stopped, Voegelesaid. Controlling the free grazing of goats and sheep was the biggest challengefaced by the Government and the Bank team and it took a number of years ofrelentless work to achieve. Banning grazing right at the start of the projectwould have been unthinkable or impossible, but the project insisted itsinvestments should be protected.The solution was to combine incentives to move away from grazing witheducation about the damage goats did and close supervision. Whenever the Grazing bans – land closure
  14. 14. 14 As traditional breeds of sheep and goats were prone to foot infections, breeds such as Shandong Fat-tailed Sheep and South African Boer Goats were introduced. These animals produced higher quality wool or milk, and thrived in a pen environment, so livestock income for local farmers tripled. Local government officials were starting to change their mindsets – by now, they readily accepted that grazing management plans should be a prerequisite to project investments and be a part of all small watershed managementBefore project in Jixian County, 2002 plans.

The Governor stared for a long time at the lush grass waving in the wind. He turned and barked an order to his staff, “I want my whole province to look like this. I want all of you to work with our farmers to make this happen.” The progressive extension of the grazing ban to all counties in the Loess Plateau became the most cost-effective natural resource conservation measure ever enacted effectively in the region. By 2005, the grazing bans had been expanded to the entire Loess Plateau region.Same site after project, 2005
