Rehabilitating
a Degraded
Watershed
A Case Study from China’s Loess Plateau




Learning series on sustainable water and land management

T
      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 improved
the 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 in
other parts of the world. Viewed through the eyes of a farmer who returns to his hometown after a long absence, the
case study begins by describing the changes in a poor rural county that have taken place during the decade of project
implementation. Farmer Zhang is shocked to see a verdant, tree-filled landscape has replaced the brown barren hills of his
youth and that his family members and their fellow villagers have escaped poverty and are engaged in a variety of profitable
and sustainable ventures.

The study continues by analyzing how the project interventions broke the vicious cycle of environmental degradation and
unsustainable farming practices and helped catalyze a virtuous cycle that has restored the watershed and enriched the lives
of its inhabitants. It outlines the challenges facing Chinese project director, Huang Ziqiang, and World Bank task team
leader, Juergen Voegele, in designing an effective project and systematically describes the steps taken to transform the
environment. The study is divided into three parts: Part A, “Living on a Moonscape” describes the project area before the
project 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 natural
resources. A teaching note is available for those wishing to teach in a face-to-face setting. Teaching is enhanced by a series
of film clips edited by the WBI team from movies produced by Environmental Education Media Project, which filmed changes
over 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). The
objective of the program is to improve the capacity of client countries to improve land-water management and cope with
climate change. The Loess Plateau case illustrates the link between land and water management, soil-water conservation
and livelihoods in watershed management. It is particularly helpful in demonstrating the necessity of addressing food
security and poverty reduction hand-in-hand with ecosystem restoration.

                          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-

                          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,

But as they surveyed yet another barren and eroded watershed,
and listened to more villagers recount their futile efforts to
escape 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 areas

Creating a virtuous cycle: longer term investment

With the labor savings from the terraces, and their families well-fed within
one or two seasons, farmers had more time and resources, and could consider
medium and even long-term investments such as the planting and care of trees
of economic value.

When farmers provided labor, the project provided free trees and shrubs but
required that farmers sign “Use and Management” contracts. These began once
the trees were well-established. The project experimented with contracting
terms, as well as tree varieties and planting techniques to optimize survival
rates and profitability in the long-term. China’s forestry experts introduced
                                                                                    Pen feeding - sheep
innovative methods and gave technical advice, while young villagers were
trained 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 apple
trees, which thrived and began to yield within three years. By 2005, buyers of
his apples were coming from all over China, he had 10 seasonal employees and
his annual income had risen to $15,000. Bai Xin Nian, of Bai Dong village, used
a 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 used
this income to build himself a new house.
	

Creating a virtuous cycle: The grazing ban

No amount of technical help could guarantee that trees would survive as long as
goats, which ate everything in sight and ripped out the roots of the plants they
consumed, were still grazing in the areas.

The project could only really see results when grazing was stopped, Voegele
said. Controlling the free grazing of goats and sheep was the biggest challenge
faced by the Government and the Bank team and it took a number of years of
relentless work to achieve. Banning grazing right at the start of the project
would have been unthinkable or impossible, but the project insisted its
investments should be protected.

The solution was to combine incentives to move away from grazing with
education about the damage goats did and close supervision. Whenever the

Rehabilitating China's Degraded Loess Plateau Watershed

  • 1. Rehabilitating a Degraded Watershed A Case Study from China’s Loess Plateau Learning series on sustainable water and land management
  • 2. 2 Forward T 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 improved the 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 in other parts of the world. Viewed through the eyes of a farmer who returns to his hometown after a long absence, the case study begins by describing the changes in a poor rural county that have taken place during the decade of project implementation. Farmer Zhang is shocked to see a verdant, tree-filled landscape has replaced the brown barren hills of his youth and that his family members and their fellow villagers have escaped poverty and are engaged in a variety of profitable and sustainable ventures. The study continues by analyzing how the project interventions broke the vicious cycle of environmental degradation and unsustainable farming practices and helped catalyze a virtuous cycle that has restored the watershed and enriched the lives of its inhabitants. It outlines the challenges facing Chinese project director, Huang Ziqiang, and World Bank task team leader, Juergen Voegele, in designing an effective project and systematically describes the steps taken to transform the environment. The study is divided into three parts: Part A, “Living on a Moonscape” describes the project area before the project 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 natural resources. A teaching note is available for those wishing to teach in a face-to-face setting. Teaching is enhanced by a series of film clips edited by the WBI team from movies produced by Environmental Education Media Project, which filmed changes over 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). The objective of the program is to improve the capacity of client countries to improve land-water management and cope with climate change. The Loess Plateau case illustrates the link between land and water management, soil-water conservation and livelihoods in watershed management. It is particularly helpful in demonstrating the necessity of addressing food security and poverty reduction hand-in-hand with ecosystem restoration. -The Case Study Team
  • 3. Part A: Living on a Moonscape 3 S 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. As the oldest child, he had made the painful decision to leave the land his family had farmed for generations, so he could earn money to send home and give his parents and siblings a better life. Finding ways to put food on the table was an ever-increasing worry for the family. It was 1990 and while most of China was transforming, and land reform was greatly Loess Plateau (within red), China lifting productivity, these changes had scarcely touched the land 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 roads most degraded ecosystems on earth. For many, dwellings almost impassable in winter and in time of floods, the village were simply candle-lit caves. Typical of households on the was isolated from any possible market. Plateau, Zhang’s family lived below the poverty line, earning less than US$75 a year. All their time and energy was taken China’s Loess Plateau covers four provinces (640,000 square up in the struggle to feed the family with what they could km), an area bigger than Kenya. It was created two million grow on eroded hillside slopes, some so steep they could years ago by the deposition of wind-blown dust and by barely stand up. Each year the family had to rely on relief glacial till, called loess, which was left behind by retreating grain to supplement their meager harvest of drought-hardy glaciers. Loess is good agricultural soil but prone to wind millet, buckwheat and beans. To find grazing for their goats, and water erosion, which has carved deep gullies into the they 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 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 that Severe 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 task Sheep 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 in higher on the slopes and graze more livestock on the slopes trees was likely to disappear into the stomachs of the many to 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. Terracing was popular with to terrace slope lands and to increase vegetation cover, tree the villagers, and could create areas of flat land up to three planting, and building of dams to intercept sediment runoff meters wide, far better for crops than the hillside. But, even and create flat land in gullies,” Huang reflected. “Literally if anyone could afford a tractor, the narrow, hand-dug terraces every village had received funds at some point. But with could only be worked by ox and plough. They crumbled easily population pressure, continued unsustainable practices, and in heavy rain and repairing them took much labor, effectively such a large area to cover, these small investments were like wiping out any gain. Since it was often not clear who the scattering a handful of sesame seeds - there has been little terrace belonged to, the chances of repair were low indeed. visible impact.” Time for new thinking What were those trees for, anyway? Although farmer Zhang did not know it, in 1990 the Chinese As various ideas were tried and failed, farmers like Zhang had government was preparing a new project, which would finally become cynical. As the bus took him further from home, he bring lasting change to the Loess Plateau. The motivation was recalled how village leaders had organized a yearly campaign another project – a proposed US$5 billion dam to provide flood to “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. The optimism he But both the Government and the World Bank, a multilateral felt for this activity as a child was soon replaced by pessimism development bank which had been asked to loan funds for as an adolescent.

The tree varieties planted were chosen to stabilize the soil, not to bear fruit, so farmers never saw them as a source of Huang Ziqiang was now given the task to look for a income. Despite various campaigns urging them to care for comprehensive solution to the degraded watershed, working the trees, most villagers ignored any that survived. As the with World Bank agricultural economist, Juergen Voegele, trees were planted on collectively-owned village land, any team leader of the Bank project. In 1991, Huang and Voegele benefits from them would not necessarily go to the farmer spent three weeks traversing the hills and gullies of the Loess who cared for them.

  • 6. 6 the moonscape could become green and fertile. “Someone, somewhere must have tried something that worked”, they thought. But as they surveyed yet another barren and eroded watershed, and listened to more villagers recount their futile efforts to escape 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 areas could yield 10 tons of wheat per hectare, ten times as much as was produced on the steep slope land. The Loess soil had the potential to produce good crops, as long as water could be Cultivation on slopes retained 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 plateau they heard. Voegele observed a thin, fragile-looking woman top, which was collectively owned. He responded that he kneeling in a dry and barren field, a small basket at her side. preferred the wasteland, where he could be assured the When she told him she was collecting wild plants to feed her harvest belonged to him. children, because she did not have enough grains to eat, he was moved to tears – and even more determined to find a When Voegele reviewed what they had heard in their weeks solution. in the field, the problems seemed intractable. His thoughts kept coming back to three key dilemmas: How could the local Huang knew all too well about hunger on the Loess Plateau from economy be improved while at the same time conserving the his two decades of field work in the Bureau.

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.

  • 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, Shaanxi Travel 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

In disbelief, he queried the that they could break the vicious cycle of degradation that young village chief, standing beside them: “The rest of the trapped the Loess Plateau people.

So we had a choice: goats or walnuts.” She smiled again. “We chose walnuts.” Grazing had been banned in the “The multi-faceted problem of watershed degradation required village for some years. “We sold all the goats and sheep to an integrated solution, and China’s institutions had not been stop them from eating our trees.

It was a new approach. Wide terraces Wide terraces
  • 10. 10 Huang often compared the Loess Plateau dilemma to a giant person who had suffered a long illness. “Our past efforts focused on curing the symptoms (soil erosion, loss of water and surface flows), without paying enough attention to the fundamental cause of the disease (poverty, low productivity, and the vicious cycle).” Breaking the vicious cycle: Wider terraces triple food yield Juergen Voegele was adamant. “We must give something to Small dams together with terraces the people right from the start. Farmer benefits first and then the environment. Improved grain yields are absolutely critical.” Because food security was utmost in farmers’ Returning to the project area one year after its start, Huang minds, there was little point in discussing any other aspects and Voegele were elated with the results: “With a minimum of integrated watershed management, until farmers could be of 2 mu of terraced land per person, a family can grow assured of significant increases in grain yields. Breaking the enough grain to last the year; They can plant crops in the vicious cycle would depend first on filling the bellies of the same season that the terrace is constructed, so within one villagers. year, their food supply is guaranteed.” Average annual grain yields increased by over 60 percent, from 365kg to 591kg per Indeed, solving the food security problem by creating flat capita. land that boosted grain production was the key first step in On the broader terraces, farmers using machinery found that breaking the vicious cycle. Wide, well-designed terraces, cultivating the land was much less labor-intensive.

In the past, using an ox- came about almost by accident. drawn plow, it was a very hard day’s work to plow and sow seed over just 2 mu. Huang and Voegele decided to include machine-made terraces in the project when it was clear that there was not “It took me 20 days to harvest wheat manually, and we used enough available labor to build new terraces by hand. But shoulders or an ox cart to carry the wheat… Now we use the impact of the 6-12 m wide terraces, 3 to 4 times the width four-wheel tractors to propel the thresher harvester.

Farmers were cautious about investing in the new, higher- Contracts to construct the terraces were awarded, through a yielding terraces.

As a result, an “what if the land I work so hard to improve is reallocated?” army of construction teams bloomed in the region, increasing employment opportunities and stimulating the local economy National land reform was well under way in China by 1990, in many ways. Hearing stories across the Plateau, Voegele redistributing collectively farmed land to individual farmers mentally increased the projection for the project’s economic through short, medium and long-term leases. These reforms returns! However, he also knew that building terraces alone took longer to reach remote regions like the Loess Plateau. As could 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 and incentives Voegele and his team made it clear that secure land tenure was a “life or death matter” for the project. “If we are going Terracing was only part of an integrated watershed plan to finance building sustainable terraces in the Loess Plateau that was designed to rehabilitate the ecosystem AND to give with public funds,” asserted Voegele, “the farmers need to farmers the incentive to contribute to the solution. To join be given secure land tenure.” the project and benefit from the new terraces, villages must first contribute to an overall conservation plan, prepared Once Huang and Voegele took local government officials into from a detailed land-use map of each sub-watershed. the villages to talk to famers, and pointed out there could be no investment in the project without signed and sealed A crucial step was equitable distribution of productive land-use contracts, the officials were quick to make sure this agricultural land. Scattered slope plots were consolidated condition could be met. Farmers were given long-term leases into larger terraced plots, built on land that ideally sloped to the improved terraces, slope land for tree cultivation, and less 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. Plots were publicly measured to ensure transparency. Valuable flat agricultural land was also created by small warping dams built in the gullies to trap sediment. Because they now had higher-yielding land, farmers were encouraged to give up cultivating the steeper slopes, so that soil-retaining shrubs, and trees of economic value could be planted. This was a critical link, aligning the farmers’ financial benefits and the project’s ecological benefits. Tree planting
  • 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 the Apple 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, to authorities. craft a sub-watershed plan that met local conditions. For Huang, local ownership meant putting each project activity Loess Plateau farmers finally had the right incentives to under a microscope to make sure it really worked for the maintain their terraces, conserve their slope land for trees benefit of the people of the Plateau and their environment. and shrubs, and care for stabilizing the soil on their land. Sometimes this meant traditional practices used by the soil In return, every farmer, even the poor, was committed to and water conservation bureaus needed to change. Other repaying the public investment that had been made to benefit times, it meant convincing the Bank team to adapt their their 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 to for 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 different loans 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. Making sure project conditions were complied with called Creating a virtuous cycle: A sense of local ownership for a delicate balance of written contracts, moral persuasion and a long term view. Some farmers continued to plant on Large scale terracing, land tenure and detailed contracts their slope land, in defiance of their contract, after new were complicated. At first, local officials grumbled that work terraces had been built. As those farmers gained confidence could proceed faster without the bother of detailed planning in the higher yields from their new terraces, slope cultivation and contracting, and resisted some of the project conditions. gradually stopped.
  • 13. 13 Creating a virtuous cycle: longer term investment With the labor savings from the terraces, and their families well-fed within one or two seasons, farmers had more time and resources, and could consider medium and even long-term investments such as the planting and care of trees of economic value. When farmers provided labor, the project provided free trees and shrubs but required that farmers sign “Use and Management” contracts. These began once the trees were well-established. The project experimented with contracting terms, as well as tree varieties and planting techniques to optimize survival rates and profitability in the long-term. China’s forestry experts introduced Pen feeding - sheep innovative methods and gave technical advice, while young villagers were trained 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 apple trees, which thrived and began to yield within three years. By 2005, buyers of his apples were coming from all over China, he had 10 seasonal employees and his annual income had risen to $15,000. Bai Xin Nian, of Bai Dong village, used a 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 used this income to build himself a new house. Creating a virtuous cycle: The grazing ban Pen feeding –profitable new species No amount of technical help could guarantee that trees would survive as long as goats, which ate everything in sight and ripped out the roots of the plants they consumed, were still grazing in the areas. The project could only really see results when grazing was stopped, Voegele said. Controlling the free grazing of goats and sheep was the biggest challenge faced by the Government and the Bank team and it took a number of years of relentless work to achieve. Banning grazing right at the start of the project would have been unthinkable or impossible, but the project insisted its investments should be protected. The solution was to combine incentives to move away from grazing with education about the damage goats did and close supervision. Whenever the Grazing bans – land closure
  • 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 management Before project in Jixian County, 2002 plans.

To intensify livestock production, the project the bans. New policies of the government encouraged made loans to farmers to build sheep pens, cow sheds, and “return of agriculture land to forest to allow regrowth”. One provided training.

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
