management: (L: manus= hand; managere= to handle) the professional administration (being in charge) of business concerns, public undertakings, etc. Being opposite to the concept of laissez-faire (French: let act), it has been proved that managing affairs leads to better outcomes. Ironically, economists have been promoting laissez-faire for governments, implying that management of public affairs leads to worse outcomes (??). They promote the same for the exploitation of resources (??).
Traditionally, the exploitation of resources just happened by someone recognising an advantage in doing so. It is an almost universal principle that we first just do, and manage later, when problems arise. Management in general is often reactive, rather than proactive (preventative), but good management involves both. It is in the nature of looped-back systems, that reaction leads to instability due to the time delay between cause and effect. For instance, when supplies become scarce relative to demand, the price goes up, which reduces demand somewhat. At the same time, production is increased to meet the initial demand. Stocks increase, and in order to sell, the price is lowered. When saturation of the market is reached, the price may collapse. Manufacturers may go out of business. The economic system of prices determined by supply and demand is naturally unstable, leading to boom and bust in the business cycle. Only vision and proaction can stabilise the cycle, but rapid reaction helps .
When it comes to the supply from living stocks like agriculture and fisheries, an unpredictable amount of variability creeps in due to climatic factors, pests, disease, and so on. Proactive management is difficult because it is almost impossible to asses the volumes of natural stocks (fish, e.g.) and how they behave in the future. A fishery consists of many stocks which consist of clumped schools, all hidden from view.
So, management of any resource relies heavily on understanding the three
key elements: the nature of the resource (see the discourse on substance
above), the nature of technology and science, and that of humans
(see science, technology and human nature
for more details). These three roughly correspond to: ecology, economy
and society, or what, how and why. Nearly always
a workable compromise is necessary, because of many inherent conflicts
(management by compromise). Utopia is not achievable.
Time is also an important factor, often overlooked. Through monitoring of measurable qualities and quantities, and by recording these, one can obtain an impression of how the resource behaves under the influence of management. Remember though, that the stronger the forces of extraction are, the weaker the restoring forces will show in the monitored results. In a heavily extracted situation, we'll measure mainly what we do, rather than what the resource does.
The purpose of this chapter on resource management, is to present the
principles relating to the management of any resource. In doing so, a very
large number of factors have emerged, needing consideration. In order to
winnow the relevant ones out, consider first which of the many factors
are the most important ones. Remember that the limiting ones are usually
the most urgent, requiring to be managed now or in the near future. It
is also important to understand that the size of a problem is often caused
by a large number of small factors, all working independently in the same
direction. Tangible results can always be attained
simply by managing all factors, while achieving a small improvement in
each (maximising strengths while minimising weaknesses).
|Steering the ship
For those not familiar with management, think of yourself as the captain of a ship, and you have to set a course. You'll immediately ask 'where to?'. How can you set a course without knowing where you are and where you are coming from? So these should be your first questions.
Another important aspect of management is that a plan (the new course) does not necessarily need to be correct, as long as it is evaluated frequently and with honesty. If expected results do not materialise, then the plan must be wrong. It is an important principle of continuity in nature, that a changed course must immediately start to show change, although inertia requires some patience. Note that management by trial and error is far more preferable than management by belief or conviction. Furthermore, let uncertainty never inhibit management - there is always a meaningful improvement to be found.
Another point to remember is that a plan means change and change means expenditure of energy (cost). The faster the change, the more energy is required. Twice the speed means four times more energy, so frequent and gradual change is the most energy-efficient (cost the least). Another thing to remember is that, like the steering of a ship, every turn of the wheel requires at some time in the future a counter-turn, in order to stabilise the ship in its new course. Change is a destabilising influence, requiring a correction later. Thus any change leads eventually to a wrong outcome.
Although it is advisable to make small corrections in order to steer a ship, a jolt is often needed to steer a wagon out of the rut (deep track). Before executing a plan, make sure you have analysed the depth of the rut (opposition) in your organisation. Make sure you have identified the opposing forces. Now you have two courses of action, by jolting out of the rut (confrontation) or by smoothing the track (winning support). It depends on how much time is left, and whether smoothing is possible.
We have mentioned the 80/20 rule before, but wish to mention it again. The 80/20 rule was invented by business managers, knowing its value from experience. But it is indeed backed by science, although perhaps not exactly 80 over 20. In physics it is found in the bell-shaped distribution of most qualities (like intelligence, customers), and in the saturation curve towards equilibrium, both of which are applicable to management. The 80/20 rule implies that 80% of the plan can be achieved for 20% of the cost. It would indeed be foolish to manage by a 100/100 rule, which is what laws do. Management always involves a compromise, but compromises are not necessarily less efficient.
+ supposedly improves delivery: regulated by supply and demand, private interest is supposed to be effiicient, but markets can be distorted by subsidies, limited supply and high transport costs.

Abstract of a paper presented to the NZ Marine Sciences Society conference of 199?
The New Zealand fishery for Jasus edwardsii is managed by individual transferable quota (ITQ) determined by fisher catch history and imposed in 1990 in nine quota management areas. In one area, the fishery showed continuing declines in catch and CPUE (Catch Per Unit Effort) to 1993. The total quota could apparently not be caught in this area. Fishers complained that there were few legal-sized lobsters and that they caught and returned many sublegally sized lobsters. They were concerned about damage to, and mortality of, sublegal lobsters caused by handling and pot-related Octopus predation. They were also concerned about theft of all sizes of lobsters from commercial pots.
The industry was asked by the Minister of Fisheries to develop a management scheme to reverse these problems. Their scheme, developed in conjunction with recreational fishers and Maori, included
The proposal to reduce the
male minimun legal size caused controversy. However, the package was evaluated
with a simple model and then accepted by the Minister. This paper describes
the results: substantially increased CPUE since 1994, a successful shift
to a winter fishery, and a shift in length frequency towards larger sizes.
The paper will also describe a simple size-structured model fitted to the
fishery data and used to evaluate future management options.
Canada has worked out a strategy for implementing marine conservation
by means of Marine Protected Areas (MPA), which may illustrate that world-wide,
people are finding different ways of managing resources.
Traditionally, management is done by business, solutions are provided by engineers, while scientists do experiments to further their knowledge. But the advent of environmental problems has brought scientist into all these arenas. Data-less management is their discovery that resources can be managed in the absence of certainty and scientific data, because management can be done in uncertainty, and other forms of data are available:
|Integrated Resource Management
Integrated Resource Management recognises that many causes may contribute to a single problem. For instance, integrated coastal zone management (ICM) takes into consideration the combined effects of all types of land use, as well as coastal development and industrial activity. It is a holistic approach to resource management, applicable particularly to the management of down-stream problems. Unfortunately, IRM has become a catch-phrase or buzzword for activities that do not have sustainability as their goal.
|Integrated Natural Resource Management (INRM)
In many countries, governments and development agencies are turning to integrated natural resource management (INRM) as a means of safeguarding the natural resource base and improving agricultural productivity. In national planning, integrated catchment management and integrated water resource management are now synonymous with “integrated management” of land, water, and forest resources at river catchment scales, typically 5000–500,000 km2. The boundary ascribed in this case is always the physical watershed, or the boundary of the catchment. The general objective of INRM is improvement of the quality of life (less poverty) while safeguarding the natural resources. Often the boundaries of the catchment area are less important than those of the communities living there. A Community-Based Organisation (CBO) of the management of the resources appears to be the most successful approach to meet the various needs of diverse peoples. However, an overarching policy is needed as well, in order to integrate communities and river catchments into a larger framework.
|Eco System Based Management (ESB)
Ecosystem based management is the latest of buzzwords. Cynics say that it is an euphemism (a nice way of saying) for having lost the plot and not knowing what to do. (Read UNEP ESB for more detail) But let's listen to what it says.
Management of fisheries is totally different, because here humans are harvesting (as opposed to nature parks). There is critism of the 'single species' management of fisheries, negating the fact that relationships between species exist, which is a characteristic of an ecosystem. So a more 'balanced' approach may result in better management or reduced risk of overexploitation. So far so good, but the concept is rather shaky.
Firstly one must see an ecosystem as a closed loop, which starts for many with the phyto plankton, while ending in the decomposers. This is not quite the same as aiming for a balance between competing predators like humans, whales, dolphins, sharks and more. The picture shows that fish are but an insignificant part of the whole and predators an even smaller part, reason why fisheries usually recover after a no-take period.
Secondly one must accept that humans have for a very long time been active predators in the sea, competing with other predators (although not everywhere). So humans are an integral part of the system, and their needs must be acknowledged. Indeed many publications do so. But humans have expanded their influence on the ecosystem quite beyond the bounds of what is natural. In doing so, they have displaced natural predators. Evidence that these are returning once human fishing stops, is given by the Gulf of Maine herring fishery. Accompanying the stock recovery (in green) were populations of the harbour seal, minke whales and others. At present the fishery is managed at a much lower level (red curve) than 30 years ago, but the increased populations of other predators may turn out to be unwelcome, being protected species as well.
The recovery of the Gulf of Maine fishery shows that it is possible to manage stocks successfully at levels profitable for both natural predators and people. Indeed, it forces us to decide what adequate levels of natural predators are. Obviously the pristine situation before human existence, is not an achievable nor a desirable goal.
One inescapable consequence of ESB is that of maintaining a balance
in predators or if that balance has been disturbed, aiming to restore it.
So where we are harvesting bait fish (sardine to mackerel), we must also
harvest dolphins to retain the balance. Where we are taking squid, we must
also harvest seals and pilot whales. This is where proponents of ESB draw
the line, which makes ESB just a talking point.
Another major issue is that of the unnatural abundance of minke whales. Because the large whales were almost extirpated, the vacuum left behind was quickly filled by a tenfold increase in minke whale numbers. These now prevent the large whales from recovering because of competition for the same food. ESB demands that we reduce minke whales to the level they once were, which means killing tens to hundreds of thousands each year for many decades. Oops!
The extreme view of ecosystems based management says that because humans are natural (true), the global changes they cause, are natural too (mmm). We are just entering a period of large-scale but natural ecosystem changes. It is true that many species, including threatened ones, have learnt to live with, even exploit humans . For them there is more food (crops, garbage), more available freshwater (lakes, irrigation), more shelter (houses & cities, bridges & culverts), more warmth (heating in winter) and so on. We must probably accept that some of the global changes humans have brought about, can no longer be undone. We are entering a new nature which must be managed accordingly.
ESB for fisheries management
As far as ESB relates to fisheries management, it is complicating, adding considerably to the cost of management. Essentially, it integrates the following considerations:

Non-Government Organisations are well-informed action groups which put pressure on businesses and governments to change their ways. They operate both nationally and internationally, and are usually funded by influential supporters. Their activities consist of (but are not restricted to):
NGOs can also have a negative influence which comes from small ideologically motivated groups of individuals by-passing the democratic process and coercing governments into actions that are not supported by the populace. It can also create cultural conflicts by forcing western morality and ways of living onto eastern nations. Occupying the moral high ground, they meet little resistance from politicians.
