Japan had a serious deforestation problem 300 years ago as a consequence of a growing population and unsustainable forest use. Forests were overexploited by logging mainly for timber and fuelwood. By 1570 Japan's population had reached 10 million people and needs for forest products had increased correspondingly. With the advent of the Tokugawa shogunate and peace, followed by rapid growth of cities and construction of castles, temples and shrines, logging increased during the 1600s to a scale never before experienced in Japan. Conflict between villagers and rulers over the use of forest lands became intense. By 1670 the population had increased to nearly 30 million and all the old growth forest had been completely logged, except for in Hokkaido. The supply of timber and other forest products was running out. Soil erosion, floods, landslides and barren lands were becoming common. Japan was headed for ecological disaster. 

There were three principal types of forest land tenure during the Tokugawa period (1603-1867). Feudal lords tenure, communal tenure and individual tenure. Individual tenure failed to develop because individual land ownership was prohibited in principle by the Tokugawa Shogunate. Therefore, almost all Japanese forest land tenure was either the feudal lords tenure or communal. 

Access to the forest owned by feudal lords was strictly limited and those who logged illegally were severely punished. A typical example of forest owned and managed by a feudal lord was the Kiso area that was owned and managed by a relative of the Shogun.

Before the Tokugawa period, Kiso was covered with thick forest but by the late 17th century iso forest resource had deteriorated greatly. The feudal lord therefore carried out the first reform in 1665, instituting seedling protection, strengthening of patrols and selective cutting. The reform reduced timber production by half and cut the feudal lords income severely. Only a few years later the lord ordered an increase in timber production for financial reasons. Even though the reform first failed the second reform was planned in 1724. In this reform, timber production was reduced by more than 60% and this time it succeeded, carrying on for 30 years and thus allowing the forest to recover. 

During the Tokugawa period most Japanese people made their living by agriculture, managing uncultivated mountainous common lands surrounding their villages. Common forest lands provided a wide variety of ecosystem services such as timber, fuelwood, fertilizer, feed, clean water, erosion control etc. In the late 17th century, intensive forestry with artificial planting was begun by members (farmers) of the commons in response to increasing demand for wood. People planted valuable conifers such as sugi and hinoki and developing new techniques for planting, thinning and pruning plantations necessary for high-quality timber. Wandering scholars wrote silviculture manuals and traveled around the country spreading the new technology from village to village. Forest management stimulated new social institutions for the ruling elite and villagers to cooperate on timber production in a way that provided villagers incentives to produce timber: yamawari (dividing use rights of common lands among families), nenkiyama (long term leases of forest lands to villagers by the rulers), and buwakibayashi (villagers producing timber on rulers land and sharing the harvest with the elites). Slowly but surely reforesting took place. 

First of, action on the part of the ruling elite and villagers did not happen until forest resources were severely degraded and conflict arose between the two. New management practices were forced upon the population and breaking the rules meant severe punishment. Reforms sometimes failed due to financial interests and needs. Relying heavily on one sector for the majority of income was a bad strategy. A more diversified income probably helped later reforms to succeed. New forest management practices lead to the development of new social institutions that were more cooperative and respectful of usage rights. During hard times forests may have been overexploited but reforestation efforts during easier times helped prevent the worst of outcomes. The feudal lords were probably not very lenient towards villagers and ordinary people must have, at first, disliked the decision to cut back on timber production and being punished for logging in certain areas. However, they adapted to this new reality and started planting trees to meet the demand. Its a case of non-democratic rule that actually had a positive outcome in terms of more sustainable use of Japan's forests. Now, it should be mentioned that forests were again overexploitation during the second world war. And perhaps the previous reforms only succeeded due to times of peace. It also should be mentioned that after the war forests, both from common and lords lands, where taken up into public lands managed by the state. But it's still an interesting example to ponder. Perhaps a mix of both top-down and bottom-up rules is needed but to achieve successful management but its hard to imagine it happening without some amount of unpopular decision-making if the society is large.

Since the 1970s, the International Monetary Fund (IMF) have identified 145 banking crashes, 204 monetary collapses and 72 sovereign debt crises (Lietaer, 2012). This clearly points to structural instability in the financial system. Underlying this increased instability, building up over the last 30 years, is a regime change from productivity growth to consumptive growth fuelled by low interest rates, financial profits and explosive debt (Fig. 1). The result has been a succession of bubbles and crashes all leading up to the climax of 2008, which brought our financial system close to collapse (Fig. 2)

By now it should be obvious to most observers that there are many problems with our current monetary system, but how does it relate to sustainability? In the Club of Rome report “Money and Sustainability the missing link” (2012) Bernard Lietaer summarizes five elements that make the present monetary system incompatible with sustainability, including:

Are there any alternatives?

Fig. 3 Shows relative fluctuations in price for different food sectors (1990-2013)

In the price index (Fig. 3) we can see that cereal and oilseed prices have shown much stronger variation than prices for meat, aquaculture and capture fisheries. Lower volatility in fish and meat suggest higher substitution potential. Moreover, aquaculture prices have been less variable than other food commodities and thus appear to add some degree of stability to the global food system. The fact that prices in crops, livestock, and fish products move closely together indicates that the markets are highly integrated. Adding a robust aquaculture sector could improve the robustness of the world’s food system as long as it does not deplete resources or severely undermine the environment in which we produce food e.g. through pollution. 

Today 95% of human calorie needs originate from crop species of which only four (rice, wheat, maize, and potatoes) make up around ⅔ of total needs. The meat sector is comprised of around 20 different animal species of which only a handful are dominant (cattle, poultry, swine and goat). Aquaculture on the other hand currently involve more than 600 different freshwater and marine animal species. However, there is a trend towards concentration similar to that of the crop and meat sectors. The cultivation of fish and shellfish is now dominated by 35 species that together account for 90% of total global production.

Sustainable development is always about tradeoffs. This case exemplifies one way of assessing the potential benefits and risks of a certain future development. This could help improve future planning and guidelines regarding aquaculture and ecosystem stewardship for industry and society at large. The present diversity of aquaculture systems contributes stability to the world's food system. However, if not well managed to minimize the environmental damages and social injustices, aquaculture is likely to make the global food system less resilient.
