Resource Depletion in Today’s World

Land degradation

Overpopulation drives land degradations

“Resource depletion is evidence of overpopulation and the need to limit growth.”

By Dr. John J. Hidore

September 9, 2017—-Resources used to sustain people includes a variety of elements in the environment. Some sort of resource depletion occurs in almost all types of environments.

Land Degradation

Land degradation has become widespread. Degradation can take many forms. Among these are erosion by water, erosion by wind, and chemical degradation. On a global basis erosion by water accounts for over 50% of total land degradation. Wind erosion accounts for another 30%, and chemical degradation the rest.

Soil Erosion

Soil Erosion is devastating to food growth.

Soil Erosion

Soil has been the basis in agriculture for thousands of years. Some of the most valuable land on the planet consists of land with the best soil for growing crops.

Soil erosion consists of the removal of soil material, the transportation and deposition of the material. Soil erosion is widespread. In some areas the erosion has been, and is so bad the land is no longer usable for agriculture.

In grasslands, where most intensive agriculture takes place, soil erosion is widespread. In the drier parts of the grasslands overgrazing is common. Desertification often results. This is the reduction of the land to essentially desert conditions.

Erosion

Land degradation effects food production.

Deforestation

Deforestation is another example of resource depletion. Vast areas of the tropical rainforest are disappearing rapidly. It is being cleared for agriculture primarily. The huge band of forest in the sub-Arctic is also disappearing. In this case the timber is being cut for lumber.

With the loss of the forest cover, soil erosion becomes pervasive. These forests are important to the climate of Earth as well as a means of livelihood for people. Once these resources are reduced or eliminated, overpopulation inevitably results.

Soil Erosion

Human Activity and Land Degradation

Declining Water Resources

Of the water on the planet, almost all of it is salt water (97.5%) found in the global ocean. Only about 0.5% exists as fresh water in the rivers and lakes on the land masses. The remaining 2% exists as ice in the polar ice caps and mountain glaciers.

The rivers on the planet are extensively degraded due to agricultural and industrial chemicals, urban runoff and human waste. The addition of chemicals and organic matter entering the oceans is changing the chemistry of the water especially in estuaries.

Overpopulation and Resource Depletion

Resource depletion is a substantial factor in growing overpopulation and the need to limit growth. Even without a growing population, resource depletion is, and will continue, to lower the carrying capacity of the planet.

Resource depletion joins population growth, and declining human health as crucial global trends that are now catastrophic in some regions. Don’t let profit prohibit the drive for action that will prevent further destruction of our planet!

Conventional, Hybrid and Electrical Vehicles: What’s the Difference?

hybrid cars

Hybrid cars are better for our environmentl

“Things are slowly changing and, as our power grid across the U.S. changes, so will the energy available to the cars.”

By Linn Smith

September 6, 2017—-I drive a hybrid car and have been asked many times if I have to put gas in it. The answer is yes. The term, hybrid, has gotten more complicated in the past several years, as now there are hybrid gas-electric no plug-ins, gas-electric plug-ins and all electric vehicles. Conventional cars, which burn gas and diesel, release toxic fumes into our atmosphere, exacerbating illnesses such as asthma.
Though hybrids may still leave a carbon footprint in the manufacturing process, and with the source of electricity used to energize the electric engine, they still have a future of burning clean. As solar replaces the conventional sources of power in the production of these vehicles and clean energy is produced for our power plants, the carbon footprint decreases.

Hybrid cars

Hybrid vs Electric

Types of Hybrid and Electric Vehicles

Here is the breakdown in types of hybrids and electrical cars:

1. Conventional Vehicles: Use gas or diesel fuel.

2. Hybrid no plug-in vehicles: A hybrid is a car that draws energy from 2 or more sources. These cars have a regular combustion engine and battery just like a conventional car, but they also have an electric motor and battery. They are never plugged in to outlets. According to itstillruns.com, “The Prius uses an advanced charging system that allows the battery to tap into power from the Prius’ gasoline engine while using kinetic force from braking to generate additional electricity.” The electrical engine is powered by the gas engine, plus the braking system, and kicks in when driving slowly or idling, which makes it fuel efficient and reduces emissions. These cars aren’t considered electric cars, as they rely on gas for their energy. I average about 48 mpg with mine.

3. Plug-in hybrids: These cars are considered electric hybrid cars, as they rely on a conventional outlet for power plus gas. They combine a gas engine with an electric motor and a plugin rechargeable battery. They can be plugged in to a regular 12 volt outlet, allowing then to drive miles on the energy from that outlet. When the electric battery is depleted then the conventional engine kicks in, operating on gas.

Tesla Model X

Tesla All Electric cars

4. All Electric vehicles: The batteries of these cars are charged using grid electricity. They can use a 12 volt outlet or a charging unit, like the units Tesla has installed across the U.S. They are powered entirely by electricity. The gasoline engine is replaced by an electric motor which gets its power from a controller which is powered by the rechargeable battery. The controller takes in 300 volts DC and converts it into a maximum of 240 volts AC to send to the motor.

The Environmental Impact of Cars

Many people will argue that electric cars are beneficial to the environment only if the electrical source is from renewable energy. This is true, but things are slowly changing and, as our power grid across the U.S. changes, so will the energy available to the cars. Keep fossil fuels in the ground!

The Carbon Footprint of Air Conditioners

“The world’s supply of A/C units could increase from about 900 million in 2015 to roughly 1.6 billion by 2030.”

By Linn Smith

August 20, 2017—-If solar airplanes can fly, then maybe it’s time we look at solar for our air conditioning. According to a 2016 study at Berkeley National Laboratory, nations with emerging economies and spiking populations, including heavily populated India, are seeing air conditioner sales grow 10 to 15 percent a year.

What does the increase in air conditioning mean for our warming planet? The world’s supply of A/C units could increase from about 900 million in 2015 to roughly 1.6 billion by 2030. The Berkeley study says new technologies must take the place of hydroflourocarbons, (HFCs), found in most air conditioners. HFCs are growing rapidly in our atmosphere with a potential to increase the greenhouse effect faster than carbon dioxide, because they trap heat in our atmosphere at levels 1000 times greater than CO2.

Sierra Club

Sierra Club for Clean Air

Rwanda Climate Conference

In 2016, 200 nations gathered for the United Nations summit meeting on climate change. Negotiators created a deal to ban the use of HFCs in air conditioners and refrigerators, with finalization at the Kigali, Rwanda climate conference a few months later. 170 countries successfully negotiated an amendment to the Montreal protocol treaty to get rid of 90% of the HFCs. Developed counties will begin phasing out HFCs in 2019, China in 2024, and India and other counties in 2028.

Nearly all HFCs are made by a few giant western chemical companies, including Flame Guard USA in Illinois, GMC Aircon in South Africa, and OB-1 Air Analyses, Inc. in California.

building green

Cities, states and individuals must do their part in preventing climate change.

Reducing HFCs

The search is on for clean technologies to take the place of HFCs. In Australia, the Solar Hybrid Air Conditioner is offered by the company, EcoWorld. EcoWorld claims you can stay cool without the huge energy bill. This unit costs about $2700AU or $2000 U.S. dollars. You can see it at http://www.ecoworld.com.

They state:

1. Hands down this is the cheapest-to-run 3.5kW Split System Air Conditioner you can buy.
2. Stay Cool or Warm without the huge energy bills. Use it more often without regrets.
3. Pays for itself, in energy savings alone, within 7 months of running time.
4. Runs automatically between both Solar DC Power and 240V AC Mains.
5. 12000 BTU Performance without costing the earth.
6. As the sun goes down it transitions over to the mains power supply.
7. Comes with a 6 Year Australian Warranty when installed by a certified air conditioner installer.
8. Rated to cool or heat around 30-40 square meters.
9. Filters pollen particles from the air and can also dehumidify your space.
10. Helps to reduce Greenhouse Gas Emissions back at the power station.
11. Highly efficient and feature packed 3.5kW split system inverter air conditioner.
12. Uses 1kW of solar panels (typically 4 x 250W panels in series).
13. When running together with the solar panels it uses as little as 30W of 240V AC mains power which is virtually nothing compared to standard air conditioners.

Can we wait until 2019, 2024 or 2028 to cut HFCs? Will it be too late? Now is the time to take a step towards saving our planet! New technologies must replace fossil fuels and chemicals, such as HFCs, that contaminate our atmosphere!

Reduce HFCs in our atmosphere.

The Galapagos UNESCO Heritage Site in Danger

Galapagos islands at risk from climate change

Home to many rare species of plants and animals

“In 2007 UNESCO listed the Galapagos as threatened, as a number of the most unusual creatures found on the islands were in decline.”

By Dr. John J. Hidore

August 11, 2017—-The Galapagos Islands are located about 600 miles west of the coast of Ecuador. There are 13 major islands in the group, in addition to dozens of smaller rock outcrops. They were discovered in 1535 by sailors engaged in exploration. These islands are a unique treasure on our Planet.

The Galapagos Islands have been designated a UNESCO Heritage Site. When explorers first described the islands to people on returning to their home ports, most people did not believe the stories that were told.

The Galapagos Islands are significant for a variety of reasons. First, there is no other island ecosystem like it. They are home to many species of plants and animals not found anyplace else on the planet. The animals include blue footed boobies and marine iguanas. Second, it is the setting for the work of Charles Darwin in formulating the theory of evolution that was published as The Origin of Species. Charles Darwin visited the islands in the year 1835. At the time, the islands were known as Las Encantatas or the enchanted ones.

Galapagos Islands and climate change

Galapagos animals and plants are at risk due to global warming.

Climate Change is Altering Life on the Islands

Global warming has already raised the temperatures over the islands. The islands generally receive little rainfall. Parts of the islands depend on cool season fog to provide condensation for plants. Additional warming may eliminate this weather pattern which is the only source of moisture for vegetation is some areas. Increased rainfall that may come with a changing climate may also lead to the decline in many species of plants.

The warmer conditions are causing vegetation zones to move to higher elevations. The rising temperature is also affecting the ratio of males to females in some turtles. Warmer temperatures tend to produce more female offspring, a phenomenon that has been observed at different locations around the world.

The mean temperature of the surrounding ocean of the islands is rising. Like other regions that lie astride the equator, coral bleaching has now been observed to occur in the reefs around the islands. The bleaching is an indication of not only global warming of the atmosphere, but of the warming of the tropical oceans. While corals live in warm water they will not live in water that is even a few degrees above their optimum temperature range. As the ocean warms they are also expected to become more acidic. This will increase the rate at which minerals are dissolved from the reefs.

Sea level has been rising and is expected to rise even more. The only question is how much more it will rise. Estimates of sea level rise by 2100 vary  with the highest estimates rising 30 inches. Rising sea level may destroy many of the mangrove forests which are home to some unique species of birds including some species of finch.

Galapagos Islands and climate

Galapagos Islands are at risk due to climate change

Invasive Species

There is a second problem which may be a greater threat than climate change to the uniqueness of the islands. This is the introduction of plants and animals not native to the islands. It is believed there are now more than 1400 introduced species on the islands of which more than half are plants.

Many of the introduce species have been accidentally introduced. Probably among the first were rats, which jumped ship over the years. The rats thrived and the population grew rapidly. Many other species of insects and plants were probably introduced at the same time. The accidental introduction continues as other species of plants and animals come to the islands along with the importing of merchandise.

Other species of plants and animals have been deliberately introduced. Among the first were domestic goats. They were often kept aboard ship for the purpose of supplying meat and milk for a ship’s crew. On the Galapagos some of the goats escaped to become wild. Their numbers increased and they began devastating the natural vegetation. In recent years major programs to eliminate the goats have been initiated, especially on the smaller islands. In 2006, for example, a massive effort was mounted to eliminate some introduced species from several islands.

Largely due to problems related to the invasion of species, in 2007 UNESCO listed the Galapagos as threatened, as a number of the most unusual creatures found on the islands were in decline. This includes sea lions which depend on a declining food supply off shore. The changing of the plant communities is a threat to many native birds. Some of the very species of finches which were the foundation of Darwin’s theory of evolution are in danger of becoming extinct.

On the plus side, most native species are expected to survive if invasive species can be controlled. But again, additional climate warming may eliminate the weather pattern necessary for plant and animal survival!

Gothenburg Sweden: Providing Sustainability through Green Bonds

Gothenburg, Sweden

Build sustainably with green bonds.

“Local governments wield significant influence and authority that can drive environmental sustainability within their jurisdictions.”

By Linn Smith

August 6, 2017—–In the late 19th century Gothenburg developed into an industrial city. In 1987 the Minister of the Environment called parts of the city, “hell’s waiting room” which described the environment for the industrial part of the city, dirty and polluted. Chemicals were escaping into the environment and appearing in animals, fish and mother’s milk, increasing cancer risks and lowering the immune system of infants. This was the Gothenburg of yesterday!

From Industrial City to Climate Leader

Today, Gothenburg has transitioned from industrial city to a world climate leader. In 2013, it became one of the first cities in the world to issue Green Bonds. 

Bonds allow the public to invest sums of money. When a person purchases a bond they lend money to the issuer of the bond, in this case, the city of Gothenburg. In return investors are paid a specific interest rate. 

Green bonds are linked to solving our climate change disaster by providing the money necessary for a community to build sustainably. They are earmarked for environmental projects.

Gothenburg, Sweden

Go Green with Green Bonds

Building Sustainably with Green Bonds

Gothenburg offers Green Bonds to the public, which allows the city to borrow money from investors. With this money the city creates climate change projects that allow a transition from a polluted city to one of low carbon emissions and climate-resilient growth. Without the Green Bonds Gothenburg would have struggled with decisions on funding schools and daycare or moving the city toward sustainability.

Gothenburg, Sweden

Gothenburg goes green with Green Bonds

Projects Funded by Green Bonds

Some of the projects funded by Green Bonds are:

• Large scale production of biogas, providing high efficiency in production and recycling of waste heat for district heating and electricity.
• Electric cars for city and companies, with 100% electric cars in the city fleet.
• Energy efficient traffic lights
• Sustainable housing. These buildings use green electricity. Estimation shows that the sustainable housing built so far will avoid 50-60 tons of Co2
emissions in the atmosphere annually.
• Tree planting. 1710 trees have been planted since the projects funded by Green Bonds started, with a focus on a green cityscape, which effects the
urban air quality and temperatures of nearby buildings.(See https://planetearth5.com/tag/heat-islands/)
• Sustainable transportation. Improvements to the city’s bicycle infrastructure. The city offers 1,000 bikes with 69 stations in the city to leave
your bike. You can pick up a bike, ride it to your destination and drop it off at the nearest station.
• A sustainable airport. All energy at the Gothenburg airport comes from renewable sources. Heat is generated by biomass boilers. There are also
charging stations for electric cars. Take off fees for airplanes are reduced for those with lower emissions of nitrogen oxides and hydrocarbons. 75%
of the airport shuttle buses run on RME, a biofuel made from rapeseed (related to canola oil.)
• The city’s SJ trains run entirely on renewable electricity from wind and hydro power.
• A sustainable port. Gothenburg is a coastal city. Ferries and ships which are docked in Gothenburg are encouraged to connect to an onshore power
supply, which is a source of clean energy. “Providing an onshore power supply for vessels at berth can result in significant environmental gains.
Carbon dioxide emission decrease substantially and emissions of sulphur dioxide and nitric oxide are reduced to a minimum. Onshore connections also
provide a quieter environment and cleaner working conditions.”
• The largest ultrafilter built in Scandinavia. City water is treated by ultrafilter to assure the highest quality of drinking water for its citizens.

Linking Investments to Green Projects

Green Bond investing has led to greater interest by citizens in the environment, plus it creates a link between investments and speeding up green projects. 

Other cities are following suit. Toronto issued Green Bonds to finance a heat, power and cooling solar plant. Johannesburg just issued green bonds to finance green projects that will reduce greenhouse emissions and contribute to a sustainable city.

The California Sustainability Alliance said it well. “Local governments wield significant influence and authority that can drive environmental sustainability within their jurisdictions” and further influence the global greening of our planet!

A Positive Environmental Impact: Recycling Steel

recycle steel

Recycling steel will make a positive impact on our environment.

“If our government doesn’t support clean technology, then we need to clean up our own back yards to counteract this lack of environmental support.”

By Linn Smith

July 27, 2017—-In June, Acosta mining company opened the first new mine in Pennsylvania in many years, stating that 2/3 of the coal mined would be used in steel production. According to the Pittsburgh Post-Gazette, “It remains to be seen to what extent the coal industry can rebound……the industry will continue to contend with cheap natural gas and clean energy.” Not a mile from the Acosta Mine, clean energy is found! Dozens of wind turbines line the ridges!

Can we produce steel without coal? According to http://www.letstalkaaboutcoal.co.nz, “Making Steel Without Coal”, the answer is no, not at the scale we need at the present time. We produce about 1.6 billion tons of steel worldwide each year. Half of this is produced in China.

To produce 1 ton of steel, .8 tons of coal is used, emitting 2.1 tons of CO2 into our atmosphere. Producing steel and iron accounts for approximately 6.7% of CO2 emissions worldwide. This is a major contributor to climate change!

Coal and steel

Steel making contributes to climate change.

Making Steel

In New Zealand ironsand, a type of sand which has a heavy concentration of various metals, is used instead of coal to produce steel, and New Zealanders have improved on their steel plants by using by-product heat, a method of using the waste heat from steel production. This use of waste heat lessens the contaminates that are put into our atmosphere. Some ironsand is exported to other countries for steel production, but the amount available is not significant.

The most common method of steel production uses coke, a bi-product of coal. The average blast furnace used to make steel needs 800kg of coal to produce a ton of steel! Recycling steel for new products uses 50 times less coal! The average electric arc furnace (used in recycling steel) uses about 16kg of coal. We can reduce the amount of CO2 in our atmosphere by recycling steel products that are no longer used. If our government doesn’t support clean technology, then we need to clean up our own back yards to counteract this lack of environmental support. We, as individuals, can make a conscious effort to recycle, not only packaging materials, but steel.

steel and coal

Making steel causes pollution, contributing to global warming.

Any Grade of Steel can be Recycled

Steel is the most recycled material on the planet. According to Wikipedia, “Any grade of steel can be recycled to top quality new metal, with no ‘downgrading’ from prime to lower quality materials as steel is recycled repeatedly. 42% of crude steel produced is recycled material.”
You can recycle many things that may have seen better days, such as bikes, broken toasters, and cars or car parts.

By recycling steel, you are doing your part to reduce the need for new mined minerals. In fact, two of every three tons of new steel comes from steel scrap.

Recycle Steel: How You Can Help!

The American Iron and Steel Institute has put together some interesting facts about steel recycling. Here are a few of them:
1. Millions of tons of iron and steel are diverted from the waste stream to the recycling stream due to steel’s magnetic properties that make it the easiest material to separate from the solid waste stream.
2. Almost 69 percent of all steel is recycled in North America each year – more than paper, aluminum, plastic & glass combined. North America’s average recycling rate has been in excess of 60 percent since 1970.
3. More than 80 million tons of steel are recycled each year in North America.
4. For every ton of steel recycled, 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone are conserved.
5. Steel products can be recycled repeatedly without loss of strength.
6. Recycling steel saves the equivalent energy to power about 18 million households for a year.
7. When you buy steel, you’re always buying recycled.
8. More than 14 million cars in North America were recycled in 2006.
9. In 2006, the steel industry recycled enough steel from old cars to produce nearly 13.5 million new ones.
10. One scrapped car produces more than four steel utility poles.
11. 95 percent of the steel taken from commercial construction demolition sites was recycled and made into new steel products in 2002.
12. It takes more than 40 trees to build a wood-framed home. A steel-framed home—eight recycled cars.
13. All 99 pounds of steel in the average major appliance can be recycled to make new steel products.
14. Appliance motors are made from steel.
15. Steel comprises approximately 75 percent of all major appliances.

Do your part! Prevent old appliances and steel based products from taking up space in our landfills, where they will still be sitting thousands of years from now!

Global Health Problems Indicate the Need to Limit Population

Climate Change

Temperatures are steadily rising on our planet.

“There are some common symptoms of overpopulation. Widespread human health problems are one of them.”

By Dr. John J. Hidore

July 16, 2017—-At the time of this writing the global population is estimated to be about 7.4 billion. It is growing at the rate of a billion every 12 years. Earth is a finite object traveling through space with a size which is essentially fixed. An important question is whether the earth can continue to provide the resources to support a continually growing population. Limits to growth implies that there is an upper limit to the size of population a region can support.There may not be an absolute limit to growth in any region but it can still be overpopulated. The resources humans need are those things which provide food, clothing and shelter. Overpopulation occurs when the available resources cannot sustain the number of people without damage to those very resources the people depend on.

Overpopulation and violence

Overpopulation can cause world disaster.

Symptoms of Overpopulation

There are some common symptoms of overpopulation. Widespread human health problems are one of them. Among the health problems are undernutrition, dehydration, and declining resistance to disease. At present, in the early 21st Century, global food production is the highest it has ever been. However, the availability of food varies greatly from place to place. Estimates of the number of people on Earth facing food shortages today vary between 800,000 and two billion. Even if the number is that of the lowest estimate it is a significant portion of the total population.

Food shortages can result from a variety of factors. Civil wars can interrupt agriculture and interfere with the distribution of food. There are many places on Earth where this is now taking place. Syria is perhaps the best know case, but the same situation exits in many other places around the globe.

world hunger

Overpopulation depletes resources

Undernutrition is a Worldwide Health Problem

Scientific data shows that the most important factor associated with physical illness (as distinct from mental illness) is undernutrition. Globally, undernutrition is probably the greatest health problem in the world today. At this time it is estimated that more than one billion people suffer some form of undernutrition great enough to be a health problem. This is more than the population of North America and South America combined. It is clear that food production and distribution is not keeping up with demand regionally, if not globally.

Undernutrition does not mean starvation. It means those suffering undernutrition are in some way being physically affected by not getting either enough food or enough healthy food. There are a variety of types of undernutrition based on what is missing in the diet. Dietary deficiencies responsible for undernourishment include iron, iodine, vitamin A, and zinc. The extreme health problem is of course starvation.

Are there enough resources for overpopulation?

With climate change will there be enough resources for all?

Geographic Distribution of Undernutrition

The main regions where undernutrition occurs are those regions where subsistence agriculture is the predominate livelihood. This encompasses large areas of Africa and Asia. In Africa a third or more of children under the age of five years undergo growth stunting due to malnutrition. Death by starvation is most prevalent among children. Some specific areas of extensive undernutrition are in Yemen, which is in the midst of a civil war. Estimates indicate at least seven million people are undernourished. In Somalia nearly three million are in danger of severe undernourishment. In Nigeria, as a result of terrorist activity, millions of people are on the verge of starvation. South Sudan has been suffering from a long battle to obtain its freedom from the rest of Sudan and currently from tribal warfare. An estimated million children are severely malnourished with a significant portion facing starvation.

While undernourishment is largely associated with the developing countries it is found to some extent even in the most highly developed countries. The World Bank reported that in 2011 in the United States about five percent of the population was undernourished. The report also concluded that the rate in the United States had remained about the same since 1992.

Undernutrition in Children

Data for the period 2010-2016 indicates a global rate of undernutrition in children of about 23%. In parts of Africa and South Asia the rate is over 30%. Children suffer more from undernutrition than adults because of the high demand for energy and protein associated with physical growth. Some form of undernutrition affects perhaps as many as a fourth of all children. Undernourishment of a fetus and children up to the age of two can lead to a lifetime of physical and/or mental development. A large majority of these children live in developing countries.

The physical symptoms of severe undernourishment, or malnutrition, include reduce body weight or height, swollen stomach or legs, and limited energy. The most common form of malnutrition in children is kwashiorkor. It results from lack of protein and manifests itself in distended stomachs. Malnutrition is the primary cause of nearly a third of early childhood deaths.

Options to Overpopulation

There is no simple answer to the tragic developments now taking place on Planet Earth. One part of the answer is to slow, stop, or reverse population growth. Limiting population growth is an alternative to the dominant economic and political policy based on economic growth that dominates the world today. It is a viable option that would be healthy for both the human population and the planet. This part of the solution requires providing family planning to those that want it and do not now have access to it. It could be implemented almost immediately and make a difference in population growth fairly quickly. Certainly this would make an impact much faster than some other options. This would also be beneficial to women’s health. The problem is that Wall Street and many organized religions thrive on population growth and oppose any change in this direction!

Momentum for Change: Mapping for Rights

MappingForRights

Protecting our Rainforest!

“MappingForRights can improve how forests are protected and governed, making it easier to enforce illegal activities when needed.”

By Linn Smith
July 6, 2017—Momentum for Change is headed by the Climate Change branch of the United Nations. Its goal is to shine a light on the global activities which are moving the world toward a low-carbon future. It recognizes innovative solutions that address climate change and wider economic, social and environmental challenges. The solutions are called Lighthouse Activities. If you are leading a project with this objective you can apply to enter the yearly Momentum for Change Awards.

ForestLink

MappingForRights employs many women.

MappingForRights

MappingForRights is one of the winners for 2016. Specific attention is given to indigenous women, allowing them to be involved in this project. The system is based on enabling communities to map and monitor their lands through low-cost technologies, providing an online interactive map. It’s a project of the Rainforest Foundation UK and its partners in the Congo Basin.

MappingForRights puts indigenous communities on the map digitally, showing traditional lands and resources that are used to claim land rights. It also challenges harmful projects such as logging, by making all data available online, and by advocating for legal reforms. It provides communities with accurate printed maps of their lands, and allows indigenous community leaders to easily access this accurate geographical information about community lands, showing the allocation of the forests around their villages.

ForestLink

Forest Link helps monitor and protect our rainforest.

ForestLink

In 2015, the project launched ForestLink to monitor remote communities and to capture and transmit alerts on illegal logging anywhere in the world using a satellite. ForestLink shows an accurate report of illegal logging by timber or palm oil companies. The illegal activity can be collected using a tablet computer or smartphone and then transmitted to an online map via a satellite modem transmitter in as little as 20 seconds, costing about the same as a text message. This real-time monitoring of the forest transforms the way forest illegalities are documented and laws enforced, transmitting the location which leads to more targeted and effective forest protection.

Mapping for Rights

Protecting our rainforest in the Congo.

Rights of Indigenous People

MappingForRights secures the rights of the indigenous people, shifting responsibility to the local indigenous communities. The information gathered is stored in a central geographical database where it can be assessed and analyzed by experts or automatically re-broadcast for in-field verification. The reports can be searched for data related to the reports, such as name of companies involved in logging or type of infraction.

By 2017 it is expected that more than 700 communities in the Congo Basin will have mapped their lands through the MappingForRights program, mapping up to 6 million hectares (over 23,000 sq. miles) of forest land.

Protecting Our Rainforest

There is evidence that securing community rights to land and resources is one of the most effective ways to reduce poverty, halt deforestation and reduce the harmful effects of climate change. This system can improve how forests are protected and governed, making it easier to enforce illegal activities when needed.

The Sierra Club and Environmental Defense Fund: Making a Difference

Sierra Club

Supporting our environment.

“A key part of the Sierra Club’s mission is to protect the quality of the human and natural environment.”

By Dr. John J. Hidore

June 28, 2017—–Since President Trump pulled the United States out of the Paris Agreement it has become more urgent for people of this country to become climate activists. There are many ways of supporting action to reduce global warming and the related problems. One of these is becoming a member of an active non-government organization (NGO). This adds your voice to those of many others and contributes to the power of the NGO. Following are two such organizations. I selected these two out of many for the reason that they both are celebrating anniversaries covering many decades. Both have responded strongly to President Trump’s actions to eliminate pollution controls in this country.

Sierra Club

May 28th of this year marked the 125th anniversary of the group. The Sierra club was founded by John Muir in 1892. The first Sierra Club Bulletin was published in 1893. Initially the organization was focused on protecting the mountains of California from wanton destruction by logging and mining. Soon the group became active in the establishment of our national parks. During the 1960’s the federal government was proposing the building of a series of dams on the Colorado River system. The Sierra Club was a leader in the fight to leave the river system in as natural state as possible.
I remember attending a water resources conference in one of the western states and watching the heated debate over the proposed plan. The federal plan was defeated and the government came down hard on the Sierra Club for its part in blocking the plan.

Sierra Club for Clean Air

In 2015, the Sierra Club was rated one of the top 15 most influential brands in Washington, DC. This was based on characteristics of integrity, influence, and respect by policy makers. The Sierra Club was the only environmental organization to make this list. It is now the largest and perhaps best known environmental organization with nearly three million members.

A key part of the Sierra Club’s mission is to protect the quality of the human and natural environment. It is also engaged in educating people on the nature of and problems in the natural environment. It has been actively involved in a number of campaigns related to its mission. Among them are the Beyond Oil and Beyond Natural Gas campaigns. On June 5th of this year, the Sierra Club and other groups filed a law suit against the Trump version of the EPA for weakening protections from oil and gas pollution.

Environmental Defense Fund

A fund for a clean environment.

The Environmental Defense Fund (EDF)

This year is the 50th anniversary of the fund. In 1967 a small group of men gathered at the Brookhaven National Laboratory on Long Island to incorporate the fund. It was formed to challenge the use of the pesticide, DDT. Evidence was increasing that the widespread use of DDT was killing many species of birds. This included large birds of prey such as eagles, osprey and pelicans.

Brown Pelicans had all but disappeared on the coast of North Carolina along with much of America’s coastline. After six years of providing evidence of the hazard of DDT, William Ruckleshaus, then head of the Environmental Protection Agency, banned the use of DDT in the United States. Some other countries have now also eliminated the use of it, but it is still widely used worldwide and is still manufactured in the United States.

When I lived in Khartoum, Sudan, DDT was routinely sprayed in the gutters along the streets to keep down mosquitoes, but on the plus side, I am happy to report that now when I go to Wrightsville Beach in North Carolina I often see large flocks of brown Pelicans soaring overhead or skimming the waves.
Today the EDF is working on a variety of projects around the world in climate, ocean fisheries, ecosystems, and human health.

Solar Uses in the West: Monitoring the Irrigation Ditch

“It’s predicted that in the future, solar will be the main source for controlling our water systems in the West.”

By Linn Smith

June 23, 2017—In the eastern section of the U.S., water is easily obtainable. In the west, where dry land prevails, water rights are taken seriously.

How is water diverted to arid land? Irrigation ditches are man made channels that deliver water to homes, farms or industries. They have head gates on creeks and water sources to divert water to these arid regions.

Water Rights

In the West and Southwest U.S., a person diverting water through a canal needs legal rights, because there are many demands on the water between individuals, industries and cities. In the 1800’s miners depended on water rights for mining of gold and other minerals, and pioneers depended on water rights to irrigate crops far away from the stream.

Colorado developed the Prior Appropriation Doctrine which is still in use today. It states that, “The first person to divert water and apply it to a beneficial use has a prior or senior right to the water over any other user who seeks to use water at a later time.” This secures the amount and date of senior users. Water rights in Colorado are property rights and can be bought, sold or rented apart from the land through which they run, if the water is put to beneficial use.

In New Mexico a person needs to obtain a permit through the State Engineer Office. The office will evaluate and determine if water is available and would not impair existing water rights.

Irrigating

In New Mexico I helped surface irrigate (flood irrigate) a friend’s ranch from an irrigation canal, which ran above ground. Irrigating consisted of opening the irrigation gate by hand and allowing water from the canal to run over the horse pasture. We were able to control the amount of water on the pasture by sliding the gate down when the water was sufficient for healthy pasture growth. This has been the most common type of irrigation in most parts of the world.

Solar Powered Water Moniters

Recently a solar monitor was added to an irrigation ditch nearby, which runs through farmland and continues to a large lake. The gate of the irrigation ditch was previously open and closed by hand, but now a solar monitor opens and closes the gate to prevent flooding from unused water in the ditch.

In an article, Solar-Powered Automation on Irrigation Delivery Systems, it states, “The most popular do it yourself solar automation model consists of a 1/16 inch horsepower gear motor, a bicycle-type lift apparatus, (chain and sprocket) and a cover over the gate stem which contains a gate position sensor and limit switches. The gate system is usually powered by 1 or 2 deep-cycle batteries which are charged by a 20-40 watt solar panel. The gear is attached to the 12 volt DC gear motor with an industrial chain.”

It’s predicted that in the future, solar will be the main source for controlling our water systems in the West, from pumping up groundwater for cattle to monitoring the amount of water in irrigation ditches. Again, sunshine prevails!
