This is a post series expressing my humanitarian side. A friend of mine out of Lake Forest, CA does mission work through his church traveling to China, Rwanda, and Uganda. Recently, he indicated that the projects he had been doing were not progressing as they should and that many of the efforts really did not serve the people well. He attributed the problem to poor leadership and strategies with little or no focus. For example, fund raisers several times a year that are more of a social experience in LA, CA than genuinely doing good for the intended people off shore. This got me to thinking. During my military service, I was trained in civil affairs and performed many humanitarian missions of various sorts that ranged from noncombatant evacuation operations (NEOs) to civil affairs missions such as medical operations (MEDOPS) and various reconstruction projects. Often the missions were planned from a standard or template. I thought that the same ideas could serve other efforts by having a purposeful goal and elements efforts to get there.
Humanitarian
Projects Built from a Model
Many people and organizations attempt to do good around the
world. The US Navy's tagline is a force for good. Many people and organizations purchase then gift equipment and facilities to help those less
fortunate. The problem is that a short time later the facilities and equipment
fall into disrepair or become inoperable due to a lack of a sustainable
infrastructure. Thus, the act of
kindness becomes ineffective at resolving the issues it was gifted to overcome
and may become a greater burden for the recipient. The challenge is to develop
a way to overcome these issues and provide sustainable gifts to these nations
and people who require broad based support. After all, Stephen Covey tells us
to teach them to fish and feed them for life.
Making a Brief Case
A considerable portion of the worlds population lives in
temperate regions without adequate food and potable water. These societies are
often isolated from the regional and global communities. Efforts to gift
supplies and equipment have not produced the results needed for these societies
to maintain a sustainable improvement to the quality of life. A new approach is
needed.
Many challenges confront the new approach. We will not
consider political and social movements that could be counter to these efforts.
Some regions have world views that reject aid from people outside their circles
or are counter to the values necessary to sustain the new approach. Operating
in these regions requires other methods not discussed here. Nonetheless, this
is a base model that can be adjusted to local conditions.
This new approach should create a sustainable system that
introduces the society to the regional and global economies with the goal to
integrate the society into the broader and complex economy. Underpinnings of
the regional and global economies include components like a functional supply
chain infrastructure (seaports, airports, and roads), ample fresh water, and
energy distribution networks. These societies cannot be connected to the
broader system until they begin the trek towards improvements which is the
objective of this effort. Development of
a supply chain cannot begin until energy, water, and food resources are
adequately addressed on a fundamental level first. Once renewable food, water,
and power resources are available then the injection of external economic
influences will enable the people to earn increased wages and further transform
their quality of life.
The solution begins by scoping the issue and setting
objectives. In this case the people are in need of the basics; food, water, and
power. This further breaks down to fertile and irrigated soil, fresh and
potable water, as well as renewable energy. The objective is to design
solutions that are low tech, easily sustainable, and ecologically friendly. The
success of this endeavor centers on a basic economy to sustain the solution.
The design should include natural filtration and purification methods as well
as make use natural sources of nutrients and energy.
This vision is to develop a local economy poised to
introduce the local society to regional and global economies by building the
sustainable groundwork for the most basic needs of the community. This is a
major undertaking often too large for a single organization or government. Thus,
armed with this vision a coalition should be built yielding various aspects of
the vision to participants of the project.
The Sustainable
Groundwork
Many solutions for the base
problems exist with some performing better than others. As part of the project
planning performance metrics need to be determined. I have completed some basic
research into this matter and the following ideas may have some merit as they have been put to successful use around the world.
Natural Water Filtration and
Potable Water
Natural water filtration uses
earthen filtration and gravity. Natural filtration mechanisms vary by
topography and generally involve estuaries (wetlands) and riparian (stream side
forest) systems. Within these systems soil composition, vegetation, animals,
and micro-organisms play very important roles in purification. Engineering low
tech natural purification systems can reflect the local ecosystems or an
enhanced system can be introduced. Essentially, a three stage system of gravity
fed lakes and earthen berms can purify large quantities of fresh water. The source of water can be natural sources such as springs, wells, storm runoff, and general waste wate from the community etc... The system flows from an estuary lake through
an earthen berm composed of aggregates of various sizes (rock, gravel, sand,
and clay) into an intermediate lake filled with low oxygen fish. The intermediate lake is gravity fed into a
lower lake through a second earthen berm also composed on various aggregates.
Anaerobic microbial and insect lifeforms
also reside in the berms as well as trees line the lakes assisting in the
purification process. The middle and lower lakes could be split into upper and
lower halves with rapids or waterfalls providing aeration to the water another
critical aspect of purification.
The water arrives in the lower
lake as purified fresh water but remains non-potable. The water can be used
directly in irrigation and watering of animals. In order to achieve potable
water an additional level of purification is necessary to remove pathogens and
other contaminants. There are natural methods of achieving this objective that
usually involve ultraviolet light and methods to raise the water to a pH of
about 8.3. Lime, soda ash, and sodium hydroxide usually raise the pH
balance. Solar concentrators can focus
the sun's energy to a focal line where a pipe containing the fresh purified
water is passed through. The focused solar energy flashes the water to steam
which is evacuated then condensed killing pathogens and bacteria while leaving
heavier sediments behind. The steam evacuation and fresh water draw can be
created using the falling water or windmills that drives blowers and pumps.
Venturi's expand the steam causing the cooling necessary for condensation in a
plenum chamber. The potable water is then siphon fed into a water tower as
currently performed in the US.

The gravity fed lake system is in current use in San Diego, CA and smaller systems are in Florida. The fresh water is fed into the Pacific Ocean after the detention cycle. However, San Diego is undertaking a project to recycle the water's use by placing the fresh water into a reservior for the detention cycle. While the ideal topography is sloping, the system can be built on mesas, plains, and other level topographies but would require earth moving endeavors stair stepping the detention lakes.
Fertile Soil

| Figure 2: Composting System |
Many areas of the world are
inhospitable with the ecology unfit to sustain crops, live stock, or in general
human life. In fact, much of the land is undergoing desertification. An operational view of land's ability to sustain human life
considers carrying capacity and capability of the land. While a particular
stretch of land may have a low carrying capacity, natural methods are available
to improve the lands fertility and carrying capacity. Among these methods is
composting of waste materials including human waste, Figure 2. This is a low tech process does not require extensive maintenance. This improves sanitary conditions
and makes use of organic waste matter in useful ways. Tilling composted waste into the soil creates
grasslands for grazing animals that begins a cycle of renewal and economic
expansion. The compost may also be used with crops for human consumption. When using the waste for this purpose sustained temperatures must be held for several weeks in order to kill pathogens in the waste. There is a substantial body of works that promotes uses of compost. Composting Toilet Systems. A complimentary approach is the use of Holistic Management and Planned Grazing. In this approach, land is recycled preventing desertification. This approach also provides livestock and crop food sources for the local populations.
Renewable Energy
The vision is to provide the
base energy required, the minimum necessary, to support the environmental
systems emplaced. This includes pumps,
motors, and heat for composting and purification. The sun, waterfalls / rapids, and wind are sources
of potential energy to support the base energy requirements. Thus, a system of
solar panels and wind or water driven turbines could supply the requisite power
to move water around the purification system. Solar concentrators, Image 1, would focus
solar energy to sustain heat levels necessary for composting and purification. The energy production using these methods
most likely would exceed the amount necessary for the system to function. The
excess energy may be sufficient to provide security lighting during the evening
or power cooling fans as additional support to the system.

Energy is the underpinning of
an economy. Without energy logistics and tools that make the economy move would
become inanimate. The need for energy to power the full economic engine would
be an expanded effort. This requires substantial energy resources. If the
society simply does not have access to these resources locally then the
connection to a the regional and global community becomes more important. For
example, Japan imports nearly it's entire economy as raw materials including
energy then performs work in order to export the finished goods. Engineering a
energy resource for the entire community is a separate effort than this post's
intent to present a solution to stabilize the local community.
Building an Economy to Sustain
the System
Water purification, energy
production, composting systems, and holistic management require services of various sorts. For
example, the compost needs to be collected and redistributed. The solar
concentrators and condensation system may require cleaning and replacement of
the pipes. There is a need to monitor and adjust the natural filtration system
with fish and other filtration elements. These are activities that should
become part of a local economy. By
inclusion in a larger regional or global economy, resources ordinarily not
available become available as the local economy contributes to the larger
system.
Consider one cycle, a
businessmen pays a nominal rate to residents for collecting their compost. Then
sells at a higher rate the compost to land owners who in turn use it to create
grasslands and raise live stock. The landowner also pays for the irrigation
services that facilitate the grasslands for the livestock. The landowner then sells the live stock in
market as food. The residents who pay and consume the food produce the waste
for composting. The nominal fee they receive for the compost contributes
towards the purchase of more food. These
residents also perform other work in which they receive pay from perhaps a
manufacturing plant or some other inject from the complex economy originating
from the regional or global economy. Other businesses emerge such as fish farms
that not only stock the lakes but sell their overstock to the local community
as food. The local community provides financial support to the natural
purification system by buying the water they consume and paying for fishing
rights from the lower lake. Local people
are hired and trained to maintain the system. Thus, a local economy boosted by
linkage to a regional or global economy can raise up their lives.
In the end, a basic system
could be created to support improvements in food production, potable water, and
sanitary conditions that contribute towards an basic economy. This jump starts
an economy and begins the movement towards more advanced systems for further
improvements to the quality of life. More importantly, the people take
ownership of their lives.
These concepts are in successful use around the world. However, they have not been organized into a suscinct model or plan. Moreover, the end state of a society meaningfully poised for injection into a regional or global economy has not been advanced in a meaningful way.
