Seeds of Diversity

Seeds of Diversity is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Seeds of Diversity rather than just read about it. In short: Seed of Diversity, Semences du patrimoine, is a Canadian charitable organization that aims to "search out, preserve, perpetuate, study, and encourage the cultivation of heirloom and endangered varieties of food crops", particularly Canadian plants, and to educate the public about their use. It has been called "The Canadian NGO leader in two key areas of food system sustainability: crop genetic diversity and the rede…

Key takeaways

  • Seeds of Diversity belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Seeds of Diversity to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Seeds of Diversity from memory before moving on to harder problems.

Reference excerpt

Seed of Diversity, Semences du patrimoine, is a Canadian charitable organization that aims to "search out, preserve, perpetuate, study, and encourage the cultivation of heirloom and endangered varieties of food crops", particularly Canadian plants, and to educate the public about their use. It has been called "The Canadian NGO leader in two key areas of food system sustainability: crop genetic diversity and the redesign of pollination strategies". Seeds of Diversity originated in 1984 as the Heritage Seed Program of the Canadian Organic Growers organization. Members of Seeds of Diversity propagate and share seeds and other plant material, and the organization also runs a "seed library" using seed-storage technology. Educational materials related to seed saving are a major focus of the organization. Seeds of Diversity acts as a central organizing force for Seedy Saturday events across Canada.

History In 1984, Canadian Organic Growers organized a conference on the loss of genetic diversity in food crops, with Kent Whealy the director of the U.S. organization Seed Savers Exchange as keynote speaker. Inspired by that conference, COG's Heritage Seed Program was initiated to help salvage Canada's crop-plant heritage, with Alex Caron as coordinator. In late 1987, after the HSP had lain dormant for about two years, Heather Apple, as a long-term organic gardener, past president of the Durham, Ontario chapter of COG, and a Seed Savers Exchange contributor, responded to a request from Alex Caron and volunteered to reinitiate the programme. Her aim was to develop it as a grass-roots seed-saving organization modelled after the Seed Savers Exchange, and beginning with an announcement in August 1988, she produced a separate newsletter for the program which became a magazine by December 1988. By the second seed offering from HSP at the end of 1988, 14 contributing members of the program were offering 141 cultivars. In 1989, the Heritage Seed Program received a 5-year grant from the W. Garfield Weston Foundation which allowed activities and publicity to expand, and grants from various organizations were subsequently applied for and received. In 1995 the Heritage Seed Program of Canadian Organic Growers became incorporated and changed its English name to Seeds of Diversity while maintaining the French name Semences du patrimoine.

Projects

Pollination Canada Honey bees, which have traditionally been emphasized as important crop pollinators in Canada, did not exist in North America before they were introduced there by humans. In Western countries including Canada, honey bees have recently become prone to colony collapse disorder, which threatens the production of many insect-pollinated crops. Native bees are also in decline, which is partly due to loss of nesting sites in plant debris and in open untilled ground, and partly due to reduced diversity of food plants. Seeds of Diversity initiated a project called Pollination Canada with the aim of increasing awareness of native bees and alternative pollinating insects in order to protect them, so that farmers and urban gardeners can decrease their dependence on honey bees. Pollination Canada has 28 other partner organizations.

The Bauta Family Initiative on Canadian Seed Security In February 2013, Gretchen Bauta, Canadian philanthropist and daughter of W. Garfield Weston, launched through the W. Garfield Weston Foundation, a program to be administered by USC Canada and Seeds of Diversity. The aim of the program is to work with regional partners to "build a more secure and diverse ‘made-in-Canada’ seed supply" by promoting the production and use of locally adapted and diverse seed for crop plants.

Worked examples

Example 1 — a first encounter with Seeds of Diversity

Start with the simplest possible case. Write down what Seeds of Diversity claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Seeds of Diversity before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Seeds of Diversity ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Seeds of Diversity

In research
Seeds of Diversity appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Seeds of Diversity in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Seeds of Diversity is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural organizations based in Canada, Agriculture in Canada, Community seed banks, so understanding it makes those chapters shorter.
In everyday life
Look for Seeds of Diversity outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
