EARTH’S HOPE
Learning How to Communicate the
Lessons of the Loess Plateau to Heal the Earth

Looking for hope amid dire warnings.
Since being asked to document the rehabilitation of the cradle of Chinese civilization in the
Loess Plateau in 1995, the Environmental Education Media Project (EEMP) team has
witnessed a paradigm shift in human understanding and behavior, that has led to the re-
vegetation of large areas of degraded land. This regeneration has begun to return ecosystem
function that had been lost over a broad area, and simultaneously lifted millions from poverty.
The improvement in the ecological conditions has stimulated local economic growth and
altered the development trajectory, from one of human activity leading to environmental
collapse, toward a sustainable future. The psychology of the local people has also changed,
from resignation and despair, to hopeful expectation of a better life. This is being done on a
scale that is large enough to show that human impact on ecosystems does not have to be
negative.
As we continue to study this phenomenon we have begun to extract principles and definitions,
to try to better understand what we are witnessing. The more we learn about this, the clearer
it is, this knowledge is profoundly relevant today, in that it helps to address many of the
world’s most serious problems, including climate change.
In order to test our understanding we have presented to scientific bodies and in development
forums. So far, scientific and development groups making their own observations through
their work have repeatedly confirmed our findings. We also went to several countries in
Africa to see if the insights from China could help change the downward spiral that has
plagued that continent for so long. What we learned in Africa, reinforced this thesis and is
helping to stimulate new policies and actions that could lead to the recovery of ecosystem
health in many critical areas and for many break the cycle of poverty and ecological
destruction which has continued for generations.
For the global environment, all indicators are pointing toward imminent crisis. It’s becoming
very hard to ignore the warning signals. “Over the past 50 years, humans have changed
ecosystems more rapidly and extensively than in any comparable period of time in human
history, largely to meet rapidly growing demands for food, fresh water, timber, fiber and
fuel.” (The United Nations Millennium Assessment)
“Climate change presents a unique challenge for economics: it is the greatest and widest-
ranging market failure ever seen. The economic analysis must therefore be global, deal with
long time horizons, have the economics of risk and uncertainty at centre stage, and examine
the possibility of major, non-marginal change.” (Independent scientific review led by Sir
Nicolas Stern in the UK)
“Warming of the climate system is unequivocal, as is now evident from observations of
increases in global average air and ocean temperatures, widespread melting of snow and ice,
and rising global mean sea level.” (The Intergovernmental Panel on Climate Change (IPCC)
reporting to the World Meteorological Organization and the United Nations Environment
Programme)
There is much more evidence in the melting Siberian tundra, the collapsing Arctic and
Antarctic ice shelves, growing deserts worldwide, waves of extinctions, loss of biodiversity,
loss of fertility and productivity, fresh water disruptions, poverty, the disparity between the
haves and the have-nots, and of course Carbon disequilibrium. Alarm bells seem to be
constantly going off, but we mustn’t be overly fascinated by the alarms and fail to ask the
essential question. What are we going to do?
Lessons of the Loess Plateau
Generally speaking, history tends to remember human accomplishments and struggles.
Perhaps this is inevitable, since after all, it is human beings who are writing the history books.
But the great cities, the vibrant economies, the wars, the passions, all eventually recede into
legend and we are left with the ecological results. Few remember the causes but no one can
ignore the consequences, they are all around us. So what is more important? This suggests
that it is necessary to understand history in terms of what happened to non-human geological,
biological and meteorological systems, as well as what happened to the people. To really
grasp what has happened it is necessary also to analyze it from a systems perspective rather
than looking at individual impacts in isolation.
In the Loess Plateau, we initially noted that while a magnificent civilization emerged by
extracting the vital wealth of the earth, the land ultimately was fundamentally ecologically
degraded by exploitation. In order to fully understand what this meant, we began to study the
issue. In short, what we found was that five basic ecosystem functions vital to life had been
disrupted. These ecosystem functions can be broadly defined as: biodiversity, soil stability,
natural fertility, hydrological regulation and Carbon sequestration.
It was also clear that the loss of all of these ecosystem functions was interrelated. The
removal of the vegetation cover had led to the loss of soil stability. As well, the loss of
vegetation, reduced organic matter, and the loss of soil stability, further exacerbated the loss,
leading to reduced fertility and productivity. Without the vegetation and sufficient organic
matter in the soil, natural infiltration and absorption of rainfall was disrupted, leading to
continuous flooding in the rainy season, followed by drought through the rest of the year.
Finally loss of vegetation cover and organic matter in the soil, meant that the ability to
sequester Carbon had been lost over a broad area. We further found that the people of the
Plateau had in a sense devolved. Their fabled past gave way to a cycle of poverty and
ecologic destruction. So while the distant memory of greatness remained, the reality for over
a thousand years was one of continued degradation, hardship, suffering, famine and all too
often, early death.
The Loess Plateau is an almost perfect example of the fact that human activity without
ecological understanding leads to ecosystem collapse.
The Plateau has revealed additional knowledge. It has shown that degraded ecosystems have
impacts that go far beyond local ones. In the Loess Plateau this manifested itself as massive
sedimentation of the Yellow River. At the high point of erosion from the Plateau, well over
one and one half billion tons of soil eroded into the River each year, clogging infrastructure
and requiring enormous expense to contain. Gigantic dust storms also originating in this area,
wreak havoc as they sweep through surrounding parts of China, beyond to neighboring
countries and finally around the world, contributing to the greenhouse effect by altering the
transmission of light and heat through the atmosphere. This link between degraded
ecosystems in remote parts of the world and the global environment is another profound
lesson of the loess plateau.
The history of the Loess Plateau shows plainly the link between the flourishing of a
civilization through exploitation of ecological benefits derived from nature, and the loss of
ecosystem function and the end of a civilization. This has been repeatedly demonstrated
around the world. The Sumerians, the Mayan, the Easter Islanders and many others have all
illustrated this through their initial development and eventual decline of their civilizations.
While it can be fascinating to investigate what made ancient civilizations collapse, it is what
the Loess Plateau has most recently revealed that is astounding.
On the Loess Plateau we have witnessed and documented strong, visible and measurable
evidence that it is possible to rehabilitate large-scale damaged ecosystems including
returning ecosystem function that had been lost over a large area. This is the crucial
knowledge that determines whether civilizations fail because their ecosystems collapse or
whether they survive because they have learned to ensure that their ecosystems are
sustainable.
A New Paradigm
Confronted with a fundamentally degraded ecosystem it takes clear far-sighted vision to
imagine that it can be repaired. Few in the beginning really believed that it was possible to
rapidly restore ecosystem function over a broad area. Most who believed it was possible, felt
that it would take decades before ecosystem function would come back. Others felt that the
whole task was impossible. Yet in the face of doubt and disbelief in the possibility of
rehabilitation, the project went ahead. Within a decade there were visible and measurable
results showing vegetation cover returning over a large area and with it renewed fertility,
productivity, economic and social improvement, and increased ecosystem function across the
board. There is even significant and measurable improvement in Carbon sequestration,
crucial to lower human impact on Climate Change.
This is exactly what the world needs now, a way to reverse generations of ecological
degradation and to reestablish a sustainable relationship between human beings and the
Earth.
Attention must be paid. This change essentially reversed four hundred generations of
negative ecologic behavior and changed the trajectory of the development curve from
collapse toward sustainability. This means that the point of intervention is the shift to a new
paradigm in human understanding and behavior that determines whether civilizations survive
or fail. This has profound implications for everyone.
Principles
Several principles are beginning to be defined by the accomplishments of the rehabilitation of
the Loess Plateau. These include:
Unsustainable Agricultural Practices Must End: In the Loess Plateau as in many other
parts of the world this is first and foremost cutting down of trees. Once the trees are gone the
people tried planting on the sides of steep slopes and finally they free ranged goats and sheep
until the land was virtually denuded. These practices have been banned. But it is not possible
to just to tell people who are living at near subsistence that they must stop doing the only
things they know how to do to make a living. Sustainable alternatives were devised, training
was provided, and a significant investment was made. This allowed the people to transition to
a new sustainable way of life.
Ecological and Economic Land Must be Differentiated and Designated: The
differentiation and designation of ecological and economic land is emerging as an important
principle. It is absolutely essential that in order to have functional ecosystems, at least some
of the land must be allowed to provide these essential ecosystem functions. If, as happened in
the Loess Plateau, people exploit every inch of land for economic return then the outcome is
already determined.
We mustn’t stand about shaking our heads in confusion when ecosystems collapse. It is
completely understandable, measurable and even predictable. But just as with degradation, if
sufficient land is designated as ecological it is completely understandable, measurable and
predictable the extent of rehabilitation. Given the fact that we require ecosystem function for
survival, it follows that we need designated ecological land. When we understand this and
apply it, we have a model that will ensure sustainable, functional, and healthy ecosystems for
future generations. And conversely if we fail to understand this, we are faced with growing
deserts, more and more poor people and the prospect of the failure of civilization.
In trying to determine the difference between economic and ecological land it was necessary
to determine criteria. For the Loess Plateau, the authorities found that any slope over 25
degrees was unsuitable for agriculture because whatever you could produce there would be
worth much less than the ecosystem functions that you lost. This also requires recognizing
the value of ecosystems and factoring them into a new economic model. This new economic
model is very important because it contains the theoretic basis of a future sustainable human
society.
There are other principles and the exact actions taken by the Chinese in the Loess Plateau
such as banning tree cutting, planting of crops on steep slopes, free ranging of goats and
sheep, providing training in new alternative livelihoods, legal frameworks for long term land
tenure to farmers, sufficient investment, etc. that have been explained elsewhere. For
additional information please visit www.earthshope.org or www.eempc.org.
Ecosystem Function = Ecosystem Benefit = Value
In every continent there are examples of large-scale ecosystems that have been fundamentally
degraded by human activity, even to the point of collapse. But evidence in the Loess Plateau
and elsewhere proves that it is not necessary for humans to continue to degrade the
environment. In fact, in order to survive, human beings have to reverse this trend.
But if it isn’t necessary to cause degradation, then why does it continue?
One reason can be seen in economic evaluation, the relative values given to various things
which benefit us. As long as commodities are given financial value but ecosystem functions
and the benefits they provide are not given a value, then a goat devastating the vegetation, or
a bean or a banana forced from the side of a mountain, is considered more valuable, than a
river flowing naturally down out of the mountains and through the plain, or a forest quietly
ensuring biological diversity, fertility, natural infiltration and absorption of water, Carbon
sequestration and oxygen. As soon as any conceivable value for natural ecosystem functions
necessary for life is factored in, it is impossible to consider the bean or banana as anywhere
near as valuable.
Another issue is the difference between individual benefit and collective benefit. The
destruction and rehabilitation of the Loess Plateau is helping to show that individuals benefit
from collective understanding and action that leads to restoration and conservation and that
both individuals and the society suffer when ecosystems are degraded. This understanding
seems to be a required part of the new paradigm. As long as individuals selfishly serve
themselves it will be difficult or impossible to restore large-scale damaged ecosystems.
Ironically, their selfish behavior can only provide short-term benefits for them as they will
ultimately have to face the consequences with everyone else when ecosystems collapse.
The reality is that we have failed to understand the economics of ecosystem logic.
Repeatedly through history human beings were shocked to see that Nature would eventually
settle accounts for wasteful and destructive behavior. Again and again it has been proven that
we all pay and we either pay now or we will most definitely have to pay later.
Significantly, the benefits of intact ecosystems are not limited to the local people, everyone on
Earth benefits, this suggests that the local people should not have to bear the responsibility of
restoring and maintaining these ecosystems alone. If you consider whether poor people living
near subsistence have the scientific understanding, technical capacity, management skills or
capital to successfully rehabilitate large-scale degraded ecosystems that have suffered for
generations, the answer is probably no or they would have already done it. If you consider
that the interests of these people and the interests of people everywhere are the same and you
ask the same question, you get a much different answer.
There is no doubt that the world possesses the scientific understanding, technical capacity,
management capacity and capital to restore ecosystem health to many areas that are now
degraded. When considered in this light it is possible to see that everyone benefits from
functional ecosystems wherever they are and that the restoration, protection, and
conservation of the Earth’s resources are not the responsibility of some but the responsibility
of us all.
Whether or not to rehabilitate all degraded land on earth is a choice that we will either make
consciously or we will have made by inaction. If we fail to act, then the outcome is already
known as we experience the continuing loss of biodiversity, increasing deserts, more and
more poverty, shortages of fresh water and ultimately massive climate change caused by
Carbon disequilibrium. Each of us must now make a choice. What will you decide?
Investment
The rehabilitation of the Loess Plateau was not free and investment is most definitely required
in integrated poverty eradication and large-scale ecosystem rehabilitation. Five hundred
million dollars was invested in the Loess Plateau rehabilitation over 10 years in an active
project area of 35,000 square kilometers. Another benefit of the project planning has been a
more accurate type of economic calculation. Instead of calculating only the cost of
rehabilitation, the costs of rehabilitation were calculated in comparison to the cost of
mitigating the silt deposition downstream. In comparison with the infrastructure replacement
and mitigation costs downstream for the high level of silt, the rehabilitation proved to be
vastly less expensive. When you then realize that this equation is favorable with only a single
factor, silt caused by erosion, you can begin to imagine what the real value of rehabilitation
may be when the value of biodiversity, natural fertility, hydrological regulation and Carbon
sequestration are factored in.
In China, where there is growing disparity between coastal and inland opportunity and
income, the Loess Plateau Watershed Rehabilitation is further supporting the thesis of wide
responsibility and investment for rehabilitation from non-local sources. This is a strong
theoretic tenet of a “Socialist Market Economy” and in this case it is possible to see the
strength and possibility this represents.
Relevance for Africa
In Autumn 2006, with the support of British Department for International Development
(DFID), the British Department of Environment, Food and Rural Affairs (DEFRA), the World
Bank, Rothamsted Research Institute and the Jane Goodall Institute, we spent two months in
Africa, traveling to South Africa, Rwanda, Tanzania and Ethiopia. In Africa, we had two
main activities. First, we presented our films and experiences over the course of our
documentation of the Loess Plateau. Second, we began to document on videotape the
situation we found in each of the African countries we visited, concentrating on three areas;
large degraded areas, best practices in land management and pristine natural environments.
When we began to examine the situation in Africa, we found parallels in many places with the
experience on the Loess Plateau. Viewing the situation through the filter of our experiences
in China, helped us to see the problems of Africa in a new light and to imagine some
solutions.
South Africa
We began our Africa mission in August in Cape Town at the Global Environment Facility
(GEF) meeting. We presented the “EARTH’S HOPE” message together with video from the
Loess Plateau, to assembled dignitaries and experts from around the world. I’m proud to say
that the presentation was positively received. We also presented to the New Partnership for
African Development (NEPAD) executive committee who also saw the value in promoting
best practices and integrated strategy.
Rwanda
Rwanda is called the land of thousand hills because of the mountainous landscape. We stayed
in the Hotel des Mille Collines in Kigali, made famous by the film, “Hotel Rwanda”. Rwanda
is struggling with the aftermaths of genocide and one of the fastest growing populations in the
world. Although one cannot help but be touched by a profound sadness that permeates
Rwanda, life must go on and the people are working hard to emerge from their collective
tragedy.
Most of the people in Rwanda live in the countryside and try to make a living from
agriculture on small plots. The growing population and lack of alternatives to small plot
farming have taken a huge toll on Rwanda’s forests. Rwanda’s forest coverage is the lowest
in the Central part of Africa. Everywhere throughout the country small farmers are trying to
grow crops right up the sides of the hills. Given these facts, it is perhaps not surprising that
we found a cycle of poverty and ecologic destruction that is further reducing the vegetation
cover alarmingly. This is causing massive soil erosion, reducing fertility and disrupting the
natural ability of rainwater to infiltrate and be absorbed by the soil and the plants. Without
this natural absorption during the rainy season, flooding is almost inevitable. In turn, in the
dry season, since the organic matter in the soil and the plants that would normally absorb and
release moisture throughout the year are gone, the land is parched by human induced drought
conditions.
The value of natural hydrological regulation came clearly into focus for Rwandans when the
water table in the highland wetlands to begin to fall. This caused a disastrous drop in the head
and flow of waters used for generating hydroelectricity. The generating capacity was
calculated based on the functional wetlands, the lack of water has left expensive electrical
generation equipment sitting idle because the flow is insufficient to power the installed base.
Downstream, the industries that rely on the electricity are cut off from the power they need
and either have to run below capacity or supplement the electricity with expensive and
inefficient private generators. This then hampers social and economic growth.
Further ecological damage comes from erosion during the rainy season. This redistribution of
soil further leaches productivity in agriculture reducing agricultural yields and income. The
eroded soils are also clogging the downstream infrastructure. It is now possible to see
Rwanda’s rivers running yellow, filled with sediments completely caused by human
degradation. The enormity of the disruption becomes apparent when you realize that Rwanda
is the home of the headwaters of the White Nile and the Congo Rivers. If these great river
systems are disrupted at the source, then there will inevitably be serious downstream
consequences.
Our visit to Rwanda seems to have been extremely effective. When we presented the lessons
of the Loess plateau in Rwanda, they listene with great interest and respect. We were able to
present to the Prime Minister, to crucial cabinet ministers, to key personnel in the Ministry of
Environment and Ministry of Agriculture, to scholars at the National University and other
universities, to the donor community, to international NGOS, and to the press. Our thirty-
minute film on the “Loess Plateau Watershed Rehabilitation Project” was repeatedly
broadcast on the National Broadcasting System.
Rwandans were seriously seeking answers to break the cycle of poverty and ecologic
destruction. We were invited to visit and present our findings by high levels of the Rwandan
government. Using what we were calling the “direct dissemination strategy” described
above, we were able to rapidly bring about a consensus of understanding within the policy
and implementation communities in Rwanda. Following our visit Rwanda has revised its
land use policies and officially requested assistance from the World Bank, British and Chinese
Governments to begin a nationwide project based on these principles.
The entire country of Rwanda is only 27,000 square kilometers. In comparison the Loess
Plateau is 640,000 square kilometers and the active project area of the rehabilitation was
35,000 square kilometers. For Rwandan rehabilitation to work, this new understanding, new
policy and new actions, will have to protect the approximately 40 percent of Rwandan land
that is unsuitable for agriculture and much more valuable as ecological land. Simultaneously
Rwandan farmers will have to learn to use new crops and new techniques to intensify farming
on the agricultural land in a sustainable way. And globally all of us will have to understand
that our future also depends on restoring ecosystems like this and that we have a
responsibility to support these efforts scientifically, technically, managerially and financially.
Based on what we have seen taking place in China, the potential for rehabilitation in Rwanda
is excellent. While the Loess Plateau receives only 250 – 800 millimeters of rainfall per year,
the annual average in Rwanda is over 1100 millimeters and where the ecosystem has not been
disrupted it receives around 1600 millimeters. Rwanda is also able to generate biomass
quickly which bodes well for rehabilitation. In addition, because much of Rwanda is at
higher altitude the soil organic matter more emulates soils in the temperate regions than lower
lands in the tropics, which means increased Carbon fixation potential when the land is re-
vegetated.
Needless to say, we are very excited and hopeful about the developments in Rwanda.
Tanzania
I first visited Tanzania at the invitation of Dr. Jane Goodall in 2002, when we made the film
“JANE GOODALL – CHINA DIARY” for National Geographic. When Jane heard that we
were visiting Rwanda and Ethiopia in 2006 to present the “EARTH’S HOPE” message, she
asked us to include Tanzania. Through Dr. Goodall’s connections we were invited by the
Vice President’s office at the President’s request. The Executive Director of the Jane Goodall
Institute in Tanzania was instrumental in helping us arrange our presentations and in filming a
cross section of ecosystems in Tanzania.
Compared to Rwanda, Tanzania is a very big country. Tanzanians are rightly proud of the
national parks and game reserves that protect approximately one third of Tanzanian territory
and are home to an estimated twenty percent of Africa’s large mammal population. While the
land inside the National Parks and protected areas that entice high paying tourist on safari is
well cared for, large areas of Tanzania, where people are living is rapidly deteriorating.
As in Rwanda, ecologic damage is causing the water table to drop. Again this affects
hydroelectric generation and is reducing the amount of energy available for Tanzania to
develop. What we saw was growing competition for scarce land resources. Much of
Tanzania was traditionally savannah or grasslands. Traditional pastoralists want to continue
their way of life but when they increase the size of their herds with no increase in land this
puts undue strain on the land. At the same time, land is being shifted to cultivation or non-
agricultural uses increasing the stress. Something’s got to give.
What we learned in our documentation of the Loess Plateau rehabilitation was that,
designating ecological land didn’t mean protecting land hundreds of kilometers away in a
national park. It meant that ecological land is needed everywhere. Each watershed needs to
be analyzed individually and from top to bottom optimized for ecosystem function. By
protecting land for its ecologic functionality you are also improving the fertility, moisture, and
stability of the economic land.
In Tanzania, we presented “EARTH’S HOPE” a number of times to the Vice President’s
office, other Tanzania government officials, scholars, activists, development professionals and
the press. We also reached the entire country via television. Not only did the Tanzanian
National Broadcaster repeatedly air the 30-minute film on the Loess Plateau Watershed
Rehabilitation Project but I was also gave a 30-minute interview which was broadcast
nationwide.
We did our best in Tanzania to communicate rapidly the importance of this information. We
hope that it has sparked continuing discussion and research that will help this important
African nation to protect its natural resources and help raise its people from poverty.
Ethiopia
Hosted by the “Productivity Safety Net Project” and the World Bank, we traveled from
Tanzania to Ethiopia for the last leg of our 2006 Africa trip. We found Ethiopia to be
something of a paradox. While it has large, entrenched ecological problems and widespread
poverty, it also has tremendous potential for rehabilitation.
Ethiopia is an ancient country and the cycle of poverty and ecological destruction is very well
known there. Ethiopia has long received foreign assistance, often as humanitarian food
assistance. This strategy has in large part failed, as over this same period Ethiopia’s
population has tripled and the level of land degradation has increased, so Ethiopia is now
further away from being able to feed its people than it was before.
According to the President of Ethiopia the tree cover is below 3 percent in a land that
traditionally was forested. Ethiopia has been unable to feed itself. Poverty is widespread and
as noted before famine is only averted by annual shipments of food assistance that has
continued for decades. There are armed conflicts with neighboring countries, deep distrust
among the political elite, and a string of failed development attempts. From a socio-economic
perspective, based on current trends and traditional criteria, Ethiopia seems mired in
problems.
Interestingly, when contemplated from the perspective of what has been learned in the Loess
Plateau, Ethiopia seems like an enormous opportunity. The criteria for rehabilitation are
really excellent in Ethiopia. In some ways there is greater potential for rehabilitation in
Ethiopia than in the Loess Plateau. There is for instance sufficient rainfall in Ethiopia, from
500 to 1500 mm per year, compared with 250 to 800 mm per year in the Loess Plateau. There
is the enormous potential to generate biomass that comes from Ethiopia’s location in the low
latitudes near the equator. There is even very favorable Carbon sequestration potential in the
higher elevations because the decay of organic matter is relatively slow for the tropics given
the high altitude.
Perhaps most favorable is that there is already sufficient funding for large-scale ecosystem
rehabilitation going to the country through multi-donor strategies like “The Productivity
Safety Net Programme”. The funds go to pay poor Ethiopians for their labor. If that labor
were directed in integrated poverty eradication and large-scale ecosystem rehabilitation there
is every reason to believe that it would work. Already innovative solutions have been tried in
isolated pilot areas and have proven successful. Examples of community based integrated
watershed management led by well-trained leaders are showing the way. Multi-story
cropping providing diverse, high yield, high value harvests at various times in the year are
showing how to replace unsustainable grain production. Cut and carry fodder systems that
increase animal yields without allowing them to decimate the vegetation cover have proven
successful in Ethiopia. And when fundamentally degraded areas have been set aside they
have returned through natural succession to completely functional forest ecosystems. When
these efforts are joined up and this is applied to the entire country then there is most definitely
hope for Ethiopia.
Horn of Africa Regional Environmental Network
In December 2006, I was asked by the Dutch Government to return to Addis Ababa to present
to the Horn of Africa Regional Environmental Network, serving Djibouti, Eritrea, Ethiopia,
Kenya, Somalia and Sudan. Presenting to environmental experts and academic leaders from
the front line of sub-Saharan desertification was one of the most satisfying presentations I
have made so far. In this region, where ecological collapse is well known and where many
people face armed conflict on a daily basis, it was possible to reach collective understanding
and consensus in support of the “EARTH’S HOPE” thesis. This suggests that the strength of
this idea could help bring peoples together to heal more than the just physical wounds we
have inflicted on the Earth over the generations.
Survival and Scale
We need to contemplate what is at stake and the scale of what needs to be done. There are
now 6.5 billion people on the Earth and we are adding one billion people every twelve years.
That means that in 12 years from now there will be 7.5 billion, in 24 years there will be 8.5
billion and in 36 years there will be 9.5 billion people, unless current trends change. It is
clear that humanity is going to have to make collective decisions on a global scale in order to
survive. To have any realistic hope for the future, we need a global vision, which everyone
can understand and agree with to, fundamentally address the ecological problems we face,
return humanity to some sort of equilibrium with the planet, and finally, end the cycle of
poverty and ecological destruction, once and for all. Perhaps it’s a good thing that in order to
do this we will have to overcome racism and conflict.
The Loess Plateau Watershed Rehabilitation is providing a functional model for integrated
poverty eradication and large-scale ecosystem rehabilitation which explains the scientific
basis for rehabilitation, while simultaneously defining the role and responsibility of those who
live in poverty, at the edges of large degraded ecosystems, and, the role and responsibility of
those living in wealth far away. Remarkably, the interests of both groups are the same. Both
require, that the ecosystems degraded by human beings over millennia be restored, in order to
survive in the long run.
It’s difficult but necessary to contemplate the size of these thoughts. The scale needed to
succeed means that all degraded land which can be restored everywhere on earth needs to be
rehabilitated. The shared responsibility and the degree of difficulty require the participation
of people all over the world. If this isn’t done, then the current trends of increased
population, declining biodiversity, growing deserts, reduced natural fertility and productivity,
disrupted fresh water supplies and massive Carbon disequilibrium, will ultimately cause
modern civilization to fail. But if the understanding emerging from the Loess Plateau and the
actions that this understanding demands, are implemented globally, then we have a chance to
correct the fundamental imbalance that has plagued humanity throughout its history.
The Lessons of the Loess Plateau
1. Functional ecosystems gave rise to life and are necessary for life to continue.
2. Ecosystem degradation has local, downstream (regional) and global impacts
suggesting that we must rethink the way we see our relationship with the Earth. This
is an essential part of globalization.
3. Human activity without ecological understanding leads to ecosystem collapse.
4. Poverty and ecological destruction are interrelated. You must solve them together.
5. The collapse of ecosystem function is linked to the collapse of civilization.
6. It is possible to rehabilitate large-scale damaged ecosystems and restore ecosystem
function that has been lost over vast areas.
7. It is necessary to differentiate and designate ecological and economic land to ensure
that there will be at least some land that is able to function ecologically.
8. In order to restore ecosystem viability it is necessary to address the root causes of the
degradation and so all unsustainable agricultural practices must end.
9. In order for unsustainable agricultural practices to end, policies must reflect these
principles, alternative livelihoods must be identified, training and investment must be
provided to help transition the poorest toward sustainable behaviors. They cannot do
this alone.
10. Land tenure ensuring uninterrupted access to agricultural land for those who live near
subsistence agriculture is required or they will be forced to devastate common
ecological lands to survive.
11. Governments must understand these lessons and their policies must reflect these
principles.
12. Ecosystem function and the ecosystem benefits that accrue have not been valued by
traditional economic systems and so those systems are false.
13. The survival of people who live in or near large degraded ecosystems and the survival
of people who live in wealth far from these places in the developed world, are both
dependent on restoring viability to large ecosystems that have been disrupted or
destroyed by human activity.
14. Learning these lessons will ensure that future generations will enjoy rushing rivers,
forests, wildlife and more efficient, productive farms, as well as living in peace and
prosperity.
15. We need to understand what is at stake. History provides strong, compelling
evidence that ignoring these lessons will lead to ecosystem collapse and the end of
our civilization.
16. When we look toward the future do we see growing deserts, more people living lives
of desperation and poverty, or do we see forests, rivers, healthy and wealthy people
with a sustainable future? These are two different paradigms. When we achieve the
second paradigm the entire dynamic changes. This is exactly what is needed now to
address climate change, poverty, and ecosystem health. The lessons of the Loess
Plateau help to illustrate a sustainable future for humanity and represent “EARTH’S
HOPE”.
