Interfaith Hunger Coalition Participates in End Hunger in New Mexico Summit

0

The Interfaith Hunger Coalition was present at the End Hunger in New Mexico summit this past Wednesday and Thursday.  Ellen Buelow (Holy Rosary Catholic Community) led a workshop  with the help of Judy Messal (All Saints Lutheran Church) and Kathy Freeze (Catholic Charities of Central New Mexico). The workshop presented the history, goals and mission statement of the IFC as well as some data on hunger in New Mexico (courtesy of our partner New Mexico Voices for Children.

While most of our work has been in Albuquerque, many of the participants in the workshop were from communities elsewhere in New Mexico, including Roswell, Ruidoso, Cloudcroft and the Navajo Nation. In addition to learning about the IHC, participants shared their experiences and challenges working with people who are vulnerable to hunger.  For the members of the Chaves County  J.O.Y. Centers (pictured at left), a main concern was hunger among seniors.

 We also had a display table coordinated by Bert Scott (Central
United Methodist Church). Most of the materials for the display were designed by Jeanne Elmhorst (Albuquerque Mennonite Church).  Many people volunteered to staff the table, including Joy Dinaro (Immaculate Conception Catholic Church) and Ian Wood (Archdiocese of Santa Fe), pictured at left, Carole Everton (Holy Rosary Catholic Community), Kathryn Arndt (Community of Hope) and others . We hope that our presence at the summit allowed more people to know about us, which is an important step in the growth of our coalition.

Arctic Char In Sustainable Farming

Arctic Char Growing In Tanks
My experiences raising Arctic Char in land based farms using tanks and raceways, with groundwater supplies and water recirculation aquaculture systems, have been positive overall.

I am what you may call a Charr fanatic since the early eighties and most of my experience has been hard won. The road to now has had its share of bumps and even a couple of cliff sized falls. There have fortunately also been some sunny times and even pay days. It has been interesting and rewarding in many ways but also frustrating at times.

I have grown Char at stocking densities that exceed the normal for rainbow trout or salmon in similar farming systems. In a properly designed and operated land based farm, this factor can lead to increased production amounts per unit of rearing space. The high density stocking characteristics of the species can allow the production intensification necessary in controlled systems and provide increased economy of scale, helping to offset the increased costs of building eco-friendly land based fish farms.Full article published at northernaquafarms.com "Arctic Charr Aquaculture - History and Experiences in Canada"

Al Jazeera Report Highlights Nutrition Crisis in Navajo Nation

0

One way the U.N. hopes to end hunger: encourage sustainable food production among indigenous peoples by 2030. On the Navajo Nation, some tribal citizens are already on that track. “When we raise our own sheep, we’re able to sustain ourselves,” said Aretta Begay. “We’re able to feed our own family, whether it’s big or small.” But progress in Navajo Nation, with its high poverty rates and long-standing lack of access to nutritious food, will be an uphill battle.  article in Al Jazeera America

Source: Diné Policy Institute. Map by Alex Newman/Al Jazeera America.
The problem of hunger and food insecurity in the Navajo nation has been well documented. With fewer than a dozen grocery stores to serve nearly 300,000 residents in an area about the size of South Carolina, access to nutritious food is almost non-existent.

"Gas stations and trading posts fill the vast spaces in between those stores, selling foods loaded with salt, sugar, fat and preservatives. According to the Diné Community Advocacy Alliance, a Navajo think tank, 80 percent of food sold in the Navajo Nation could be considered junk," said a report in Al Jazeera America. "One in three residents is diabetic or prediabetic, and recent studies show that heart disease is the second-leading cause of death among tribal citizens living on the reservation."

In a  recent report to Congress, eentitled “Addressing Child Hunger and Obesity in Indian Country,” researchers found that Native American children had “approximately twice the levels of food insecurity, obesity and Type 2 diabetes relative to the averages for all U.S. children of similar ages,” said Al Jazeera America.

The Navajo nation has attempted to address the problem by proposing a tax on junk food in 2014 and eliminating an existing tax on fruits and vegetables. However, making junk food more expensive only solves the problem partially. The supply side of the equation is also important. Even if fruits and vegetables are less expensive, how do you ensure that you increase availability? Some residents like Aretta Begay grow a small vegetable garden and raise churro sheep to feed their families.“We have a huge problem with having access to good, quality food,” she tells Al Jazeera America. “We don’t have access to grocery stores.”

Providing the resources for personal and community gardens would go a long way toward addressing the problem. The dilemma is common not only to the Navajo nation but to many Indian reservations are rural areas around the country.

Fortunately, the recently announced Global Goals for Sustainable Development, and in particular Goal 2 of Zero Hunger, open the door for our public officials at all levels to find creative solutions to address the problem of a lack of food access.

"The question of food access could soon be getting renewed focus," said the Al Jazeera America report. "Starting in January, the United States will be aiming to reach the United Nations’ new Sustainable Development Goals. One of the priorities is ensuring access to nutritious food. In Indian Country, achieving that goal is a long way off."

The Al Jazeera report--written by Tristan Ahtone in Red Mesa, Ariz.,and Jolene Yazzie in Lupton, Ariz., with photos by Jolene Yazzie--is very comprehensive, offering statistics, anecdotes, graphics and other valuable information. (One resident who was interviewed for the article allowed the reporters to look into their refrigerator. Check out the full article to see what was found in the fridge).

HOW MANY FISH IN A TANK

 HOW MANY FISH AM I ALLOWED TO HAVE IN A TANK?

Aquaponics, ækw??p?n?ks, pisciponics
Aquaponics, ækw??p?n?ks, pisciponics

Again this will depend on whether the system is a commercial or backyard system, with the commercial systems requiring the correct amount of fish and plants for optimum production. The more fish there are in a system, the more nutrients there are for the plants to consume, but if there are not enough plants to consume these nutrients, the excess build up in the water can cause the fish to suffer. As a general rule, backyard systems can stock between 10 - 30 kg of fish per 1000 litres of water.

Aquaponics in Bangalore

0

Hello Everybody,
This is my first post in the blog. Aquaponics is a beautiful food production system that works for me. Its ideal for people who are in a busy schedule of their day to day job.
From my experience this system is easy to maintain. All you have to do is feed the fish twice or thrice a day depending on the kind of fish you keep, check if the pump is working and thats it.

This system has been working beautifully for me for the last year and a half.
I am using this blog to share my learnings and hope to get lot more people interested in growing your own fresh organic food at home.

Farmed Shrimp from South Asia in the News

0

A recent story in the Globe and Mail titled: The big challenge in making farmed shrimp safe to eat, states that Canadian Food Inspection Agency (CFIA), continues to find illegal substances in samples of shrimp imported from Thailand.  The story by JESSICA LEEDER — Global Food Reporter, in Monday’s 2010-11-22 globe and mail also points out that recent sample checks, by the CFIA on Thai imports have uncovered residues of antibiotics deemed illegal for food production in Canada and the United States.

Although the Canadian Food Inspection Agency only scans a fraction of incoming seafood – five per cent is the agency’s target – inspectors are still finding tetracyclines (antibiotics commonly used to treat acne) nitrofurans (an antimicrobial drug and known carcinogen banned in Canada) and fluoroquinolones (broad-spectrum antibiotics used in human medicine) in the shipments they test. None should be consumed by humans. They’re also supposed to be illegal in Thailand, a global shrimp farming giant that pledged years ago to flush drugs out of its system, which yields 550,000 tons of shrimp per year.

 “We can’t inspect one hundred per cent of every piece of fish that comes in the country, otherwise there won’t be anything to eat,” said Jeanelle Boudreau, a fish policy officer with the CFIA’s fish and seafood network. The agency is constantly adjusting its inspections to focus on “areas where there might be more issues for non-compliance,” she said.

The full Globe and mail Story can be read at this link.

“In general, it would be fair to say it [antibiotic use] has fallen dramatically in shrimp farms around the world,” said Peter Bridson, manager of the Seafood Watch Program a the Center for the Future of Oceans at the Monterey Bay Aquarium in California. “That doesn’t mean to say it’s good now,” said Mr. Bridson, who also sits on the Shrimp Aquaculture Dialogue steering committee. “It’s just that it was horrific before.” 

The Thailand shrimp farming industry is made up of thousands of small farmers. The Thai department of fisheries states that it has undertaken a major campaign to educate farmers on best practices, however reducing yield losses often outweighs concerns over sustainability. The use of Antibiotics to keep stock from becoming ill remains a tempting option to the small farmer hoping to get the best yield. Clearly more education on sustainable and chemical free farming methods is needed.

One thing you can do as a consumer is monitor what you buy and where it comes from. Buy what you trust and have the best available information on. If possible opt for foods Labeled organic or from known sustainable sources.

Meanwhile in the Basement

While the outdoor system is cycling, I’m continuing to grow indoors. I have a few rainbow chard plants that are now growing tremendously. I’ve also started some sweet peppers and heirloom tomato seedlings that I plan to transplant into the outdoor system. So far the tomatoes are growing very well, at about five inches tall. At over a year old, the pepper seeds delayed germination; however, they finally sprouted and now stand at half an inch tall. The system has many fewer plants than it can support currently: nitrate is about 30ppm at least. I plan to put this nitrate rich water into the outdoor system to kick start it for the transplants.

An Action Plan for Healthier Farms and People in New Mexico

0

New Mexico faces a stark paradox: ranking close to the top of the list in food insecurity and child and senior hunger, while about one-quarter of our population suffers from obesity and numerous diet-related chronic diseases. Public meal programs are critical opportunities for addressing the health and well-being of New Mexicans and there is real promise for those fruits and vegetables to be provided by New Mexico growers. -from The Power of Public Procurement: An Action Plan for Healthier Farms and People in New Mexico,September 2014

Over the past week we published blog posts on the links between health and hunger from the Bread for the World Institute, New Mexico Voices for Children and and First Choice Community Health Care. An important aspect of providing healthy food to the population, particularly low-income communities, is to ensure that fruits and vegetables are available at affordable levels. The produce does not need to be trucked from California. Rather, there is an abundance locally.

A little more than a year ago (in September 2014), Farm to Table and New Mexico State University (via the Department of Agricultural Economics and Agricultural Business, the Department of Plant and Environmental Sciences and half a dozen agricultural extension offices) published a report that attempts to identify and understand the potential and current barriers that New Mexico farmers and New Mexico’s public institutions face when trying to sell and purchase locally grown fruits and vegetables for their respective meal programs.

The report, entitled The Power of Public Procurement: An Action Plan for Healthier Farms and People in New Mexico, recognizes that a potentially significant market exists for the sale of New Mexico grown produce to the State’s public institutions. This is particularly true for the school districts’ food service programs.

"A large, and until recently, untapped, commercial exchange may be fostered between fruit and vegetable growers and the public officials who administer the procure-ment systems of public institutions," researchers said in the executive summary of the report. "Yet, practicalities and barriers currently impede the process."

The authors of the report make a number of recommendations at various agency and inter-agency levels, placing a strong emphasis on schools, but also on senior centers, state corrections institutions, and farming and agriculture.  Read the executive summary and the full report.

Best Plants to Grow in an Aquaponics System

 Best Plants to Grow in an Aquaponics System


There are many plants that grow well in soil less farming.  These include vegetables, aquatic plants, flowers and even fruit trees.  There are other vegetables that will not work well in an aquaponic system.  Root vegetables such as carrots, onions and potatoes should not be used in these systems.  You can grow them, but it would not be easy.  They need a medium close to soil like sand in order to grow.


So what plants should I grow in my Aquaponic system?

Leafy Green Vegetables

Cabbage and Lettuce are two of the most common grown vegetables in aquaponic systems.  They grow really well and are easy to take care of.  Other good choices are basil, peas and green beans.

Fruit Vegetables

Some of the top vegetables you see in a typical garden are tomatoes, cucumbers, squash, peppers and even corn.  They all can be grown successfully in an aquaponics system.cucumbers

Viney Plants


Plants that produce vines are a great choice for aquaponic systems.  They are only rooted in the growth bed and can grow elsewhere leaving more room for the other plants.  Examples of these are cucumbers, pumpkins and gords of all shapes and sizes. 


Flowers


Finally there are flowers.  I have seen greenhouses running aquaponics systems that are full of flowers.  You can have a successful business especially in northern areas by selling flowers to local businesses.  There are many popular flowers that can be grown, roses are lilies to name just a few.  They all will grow fast and well in this type of system.
flowers
The trick to being successful with your plants is to try a variety of plants to see which ones will grow well in your climate.  Your plants will need a lot of care at first in order for them to really take off.  You may want to find some supplements.   Seaweed is a very popular supplement that is used in aquaponic systems.  The seaweed extract are great for growth, but you need to be careful what you add to your system.  An additive that helps your plants grow, might cause issues with your fish or bacteria.  Make sure you find additives that will ensure your plants, bacteria and fish all will thrive in your system.

Aquaculture and Agriculture in Harmony

0

Points to consider based on experiences in the Prairie Region of Canada. Dec 19 2005

Recent times have seen an increased interest in Aquaculture as a potential opportunity for farm diversification; this renewed interest is encouraging and worthwhile. Much of this new interest is at a grass roots level where individual family farms are actively seeking alternate forms of agriculture and new economic opportunities. However this heightened awareness will fade unless concrete and solution oriented efforts are made at mitigating the potential knowledge and educational constraints faced by many would be participates.

To successfully integrate commercial scale Aquaculture production into an existing agriculture farm the economic considerations must be carefully examined. A farmer must be able to review and access the potential long-term benefits and become convinced that they warrant the investment required. The potential risks must be fully explored and accounted for within any financial modeling. The operation must also be planned to make the best synergistic use existing assets while still being capable of performing at an economically viable level.

I have over the years realized (through trial and error) that farm design alone does not guarantee success in the business. Sure, there are many new and exciting technologies emerging bringing improvements are good for the industry. It is exciting that recent advances greatly improved the performance, sustainability eco-friendliness of the industry. New farm designs and system technologies have made it possible that Aqua Farms can be operated in areas with limited water supplies and can be combined with other crop production to create even further on farm diversification. The technology are great and required, but Technology alone does not guarantee success.

Future fish farmers will also require comprehensive data dealing with production options, alternatives, investment required, operational costs, benefits to existing operations and other social economic factors. In addition the farmer needs to have access to training and skills development and longer term support for continual evaluation, refinements and business expansion.

Without training, good knowledge and proper management resources, it is unlikely that the average farmer wishing to diversify into aquaculture will be successful. Commercial scale Aqua Farming can require a sizable financial investments making knowledge and management ability all the more important in protecting and achieving a return on investment.

Most of the key deciding factors governing Aqua Farming investment decisions are not readily apparent or within easy access to the general public. In Manitoba, this lack of knowledge combined wuth the absense of a facility (or means) to witness the demonstration of working viable models, creates a justified roadblock in the minds of people that would otherwise embrace the opportunity. Many potential farmers do not yet have a comfort level sufficent to make the decision to invest in the industry. Their thoughts could be expressed as “let me see a working example and a business plan then I can determine if it can work for me”.

At this stage, it wouldn’t be wise to encourage new industry entrants "to attempt to duplicate a full scale commercial farm" without first getting their feet wet and gaining first hand knowledge and training.

However if the private sector and public sector collaborate in a mutually beneficial way it is likely that more effective co-sponsored research and development activities can be undertaken providing timely support to commercial operators while ensuring that more potential operators will be able to access top level up to date knowledge.

An effective means to demonstrate the farming process in a practical and scalable fashion will encourage further commercial development. Farm demonstration and training are two key ingredients in fostering future aqua farm development. These have to be made available in a manner that fits with the time and financial resources of the existing agri-business owner.

Smaller scale demonstration type farms are required to trigger growth of the provincial industry while allowing lower levels of risk exposure by future operators.

Commercially oriented demonstration farms with an information exchange component have been proven effective in furthering the development of fish farming in other locations.

A Dancing Prayer for the Second Friday in Lent

0

Who says our prayers during the Lenten season have to be solemn? What is important is that we find a way to open up to the Creator. So, in that spirit I share a couple of "dancing" prayers on this second Friday in Lent.

Dancers Prayer
(From Living Prayers)

Lord God,
With every movement I make
I long to be close to you.
May I leap with your joy,
May I stretch with your passion,
May I balance with your strength.
I give you my dance, as a prayer,
As praise,
And as a testimony.

May my dancing tell of you love
And always point the way to you.
Amen.

Water Hardness and ph in aquaponics

0

Most of us aquapons know that the health of all the creatures in our systems (fish, plants, worms, and bacteria) depends on proper pH. We also know that we are targeting pH in the 6.8 to 7.0 range but that we don’t have to worry about adjusting it until it goes down to 6.4 or up to 7.8. We also know that the best way to lower pH is with an acid, and that the best way to raise it is with carbonates or hydroxides. We know that rapid changes in pH can be very stressful to fish. And we know that the pH will probably decrease over time because the nitrogen cycle produces an acid (nitric).
But often, knowing all of this and applying it to our systems are two different things. At The Aquaponic Source, we handle questions and concerns each and every day about pH. Generally, the questions fall into one of two categories:


  1. - The water out of my tap is a pH of 8 (or more) and I can’t seem to lower it reliably. What should I do?
  2. - The pH in my system is dropping constantly and I have to add something to raise it almost daily. Is this normal?
Most pH mysteries in aquaponic systems boil down to how ‘hard’ the water is that we put into our systems. This ‘hardness’ dictates the buffering capacity of water… Let me explain.
Water from most sources has some level of mineral salts dissolved in it (purified water such as distilled or RO [reverse osmosis] filtered are clear exceptions). Among these dissolved salts are certain specific minerals that strongly affect your water pH. The concentration of these minerals in your water is often described by the term ‘hardness’, the higher the concentration of these minerals, the ‘harder’ your water is. There are two types of hardness in water: ‘carbonate hardness’, (KH), which is sometimes also referred to as the water’s ‘buffering capacity’ or ‘alkalinity’ (not to be confused with an ‘alkaline’ solution which would have a pH greater than 7) and ‘general hardness’ (GH) which refers to the concentration of calcium and magnesium ions in the water.
The general hardness of the water affects pH but it is the buffering capacity (KH) of your water that is the more critical pH factor. This buffering capacity acts like an invisible sponge that soaks up whatever acid or base is in your system, or that you add to your system, until the buffer is ‘used up’. With this sponge-like behavior in mind, imagine trying to adjust your pH. Let’s say you have a pH of 8.0 in your aquaponics system and you would like to bring it down to 7.0. You start adding our AquaDown pH Lowering Agent, and adding, and adding, and little or nothing changes. And then all of a sudden the pH plummets. What has happened? You had a strong buffer (meaning there was a lot of KH) in your system which you eventually ‘overwhelmed’. Another way of thinking about this is that you ‘filled up’ the sponge.
You can actually measure your KH level and doing so may help you manage your pH. The larger the KH number, the more resistant your system will be to attempts to alter pH. Having a higher KH level can be beneficial in a fully cycled system because the nitrification process produces nitric acid which will persistently drive pH down in an unbuffered environment. A rule of thumb is that a KH of less than 4.5 dH (degree hardness) means that you don’t have much buffering capacity and you should be checking your pH a few times a week.
How do you increase your system’s buffering capacity? When you are fully cycled and your pH drops below 6.8, add calcium and potassium carbonate (the ingredients in our AquaUp pH Raising Kit) on a regular basis once you have fully cycled and start seeing your pH decrease below 6.8. You will find that over time, you will build an excellent buffer and your system should become more and more pH stable.

Arctic Char In Aquaculture

0


Arctic Char were first investigated as an aquaculture species because it was expected that they would have low optimum temperature requirements and would grow well at the cold water temperatures present in numerous areas of Canada. It was also "correctly" anticipated that the Arctic Char would be welcomed as an alternate selection to Rainbow Trout and thus could provide producers with a unique product and a niche in seafood markets.


Canadian Arctic char are farmed in the Yukon Territory, Nova Scotia, and New Brunswick, Quebec and Manitoba. Operators in Iceland, Norway and the USA also raise Char. There are several different strains of Arctic Char being used in aquaculture. The most common strains used in Canada are derived from Nayuk Lake and Fraser River stocks. Read More Here

Good Aquaculture Attributes

The majority of Arctic char produced today are raised in land-based systems. Arctic char eggs are hatched within specialized hatchery facilities where the young fish remain until they reach ~100 grams and can be transferred to larger grow - out tanks. The initial early rearing stages of growing can take almost a year for the juveniles to reach 100 grams. Once in the production farm Arctic char exhibit a rapid growth spurt from juvenile to adulthood, with most stocks reaching market weight (1-2.5kg) within the next 12 months. Read More Here

Well Suited to Land Based Aquaculture

Land-based Arctic char rearing systems are considered to be among the most environmentally responsible fish farming designs. Facilities that utilize designs based on the principles of Recirculation Aquaculture technologies are among the most cutting edge farms. Arctic Char exhibit unique characteristics that make the species favorable to land based secure production, chief among those is its natural desire to shoal and live in high density populations. Read More Here

Excellent Market Reception

The Arctic Char is highlighted as a “Best” choice by the Monterey Aquarium Seafood Watch Guide for Healthy Oceans. The New England Aquarium lists farm raised Arctic Char as an ocean friendly species. They call it an excellent choice. Read More
