People who have been exposed to pesticides are 70 percent more likely to develop Parkinson’s disease than those who haven’t, according to a new study. The results suggest that any pesticide exposure, whether occupationally related or not, will increase a person’s risk of the disease. This means that using pesticides in the home or garden may have similarly harmful effects as working with the chemicals on a farm or as a pest controller.
… Previous small-scale human studies had suggested a link between pesticides and Parkinson’s, but this new study is the first to establish a clear correlation in a large patient population.

Peter Smithers Dies at 92; Spy With a Green Thumb – New York Times:

Sir Peter Smithers, who saw his work as a lawyer, politician, diplomat, scholar, photographer and spy as distractions from his passion for growing glorious gardens, died on June 8 in Vico Morcote, Switzerland. He was 92.
…
As a spy in World War II, he worked for Ian Fleming, who went on to create the fictional spy James Bond …
Arguably, though, Sir Peter was to gardening what Bond was to martinis. The Royal Horticulture Society gave him one of its highest awards, the Gold Veitch Memorial Medal. His garden in Switzerland — with 10,000 plants, none a duplicate — won a prize for being the best in that country in 2001. The Financial Times said it was named one of the 500 greatest gardens since Roman times.
…
Peter Henry Berry Otway Smithers was born in Yorkshire on Dec. 9, 1913. He grew up hanging around potting sheds, spending spare change on plants. His nanny was a fervent naturalist who fed him fried blackbird eggs and hedge trimmings.

At 13, he persuaded the Royal Horticultural Society to let him attend the Chelsea Flower Show, the first child to do so, The Guardian said. At his public school, Harrow, he began an index of every plant and seed packet he acquired; it grew to 32,000 entries by his death.

The Economic Value of Ecological Services Provided by Insects
Authors: Losey, John E.; Vaughan, Mace
Source: BioScience, Volume 56, Number 4, April 2006, pp. 311-323(13)
Publisher: American Institute of Biological Sciences

Abstract:

In this article we focus on the vital ecological services provided by insects. We restrict our focus to services provided by “wild” insects; we do not include services from domesticated or mass-reared insect species. The four insect services for which we provide value estimates—dung burial, pest control, pollination, and wildlife nutrition—were chosen not because of their importance but because of the availability of data and an algorithm for their estimation. We base our estimations of the value of each service on projections of losses that would accrue if insects were not functioning at their current level.We estimate the annual value of these ecological services provided in the United States to be at least $57 billion, an amount that justifies greater investment in the conservation of these services.

And from the authors’ conclusion:

… our findings lead us to espouse three qualitative guidelines. First, cost-free or relatively inexpensive measures are almost certainly justified to maintain and increase current service levels. Examples include volunteer construction of nest boxes for wild pollinators [butterfly houses?] and the inclusion of a diverse variety of native plant species in plantings for bank or soil stabilization and site restoration (Shepherd et al. 2003,Vaughan et al. 2004). Second, actions or investments that are estimated to have an economic return at or slightly below the break-even point, such as the use of less toxic pesticides, are probably justified because of their nontarget benefits. Third, actions that lead to substantial decreases in biodiversity should be avoided because of the high probability of a major disruption in essential services.
…
Once the benefits of insect-provided services are realized, there may be some call for increased funding to conserve rare insects through the Endangered Species Act. Insects are certainly underrepresented and underfunded through this legislation, and increased funding could save many rare insect species from extinction. However, while increasing funds targeted for the conservation of endangered species would help those beneficial insect species that share habitat with listed species, it would not in itself be sufficient to ensure the continuation of the services provided by beneficial insects.

Science & the City announced that another Brooklynite, Ben Jervey, has just published a book, “The Big Green Apple: Your Guide to Eco-Friendly Living in New York City.” He’s also launched a Web site, Green Apple Guide, in association with the book.

The opening to the book’s preface:

Right now, right here in New York City, somebody is cultivating a garden. [And how!] Around the corner, somebody is pocketing their car keys and hopping onto a bicycle. In some nearby kitchen, locally grown, organic produce is being kept cool in a refrigerator plugged into wind power energy. Somewhere in New York City, a street tree is being cared for by a concerned local resident, while a sanitation worker on the street adjacent is dutifully keeping the recyclable paper and plastics separate.

Although difficult for many to believe, all over the city of New York, acts of sustainable, low-impact living are being performed by a hearty bunch of citizens who recognize the inflexible connection between the quality of life in a place and the attitudes and lifestyle decisions made by those who live there.

The article presents five tips:

1. Change your light bulbs
2. Order a home water conservation kit from the
   DEP
3. Join a community-sponsored agriculture group
4. Choose your own energy source
5. Reduce, reuse, recycle – in that order!

Tips 2 and 5 are of particular relevance to gardening. Item 3 is also of interest.

Tip #2: Reduce water use. Now that we own our own home instead of renting an apartment, we see the water bill, which means we have some idea of how much water we’re using. I conserve water in the garden in several ways:

• Choose plants appropriate for the site, conditions, and climate. Native plants (appropriately sited) and drought-tolerant plants will need less water than others. Plants in sunny areas, containers, or exposed to extra heat from pavement, walls and other structures, will need more water. A rooftop garden, for example, is essentially a desert; choose and plant appropriately.
• Increase the amount of organic material, such as compost, in the soil. Organic material provides several water-related benefits, including absorbing and retaining water, reducing runoff by allowing water to penetrate the surface of the soil, and improving the soil structure to allow roots to run more deeply and widely, increasing the ability of plants to reach the moisture they need.
• When gardening in containers, use non-porous containers (I don’t always do this, but I’m mindful of it) and amend the soil with water-retentive materials such as compost or hydrogel.
• Mulch to reduce surface runoff and evaporation.
• Water only when needed. If the soil is moist below the surface, it doesn’t need water (yet). Group plants with similar moisture requirements together, so you can water them at the same time.
• When extra water is needed, water in the morning (ideally) before the sun is fully up, or in late afternoon or early evening, as the sun is going down.
• Water at or below the mulch or surface of the soil. A sprinkler loses more water to evaporation, in the air and from leaves, than hand watering at the surface. Soaker hoses reduce evaporation even more, since they can be placed on or below the mulch or soil surface. For containers, drip irrigation systems can achieve the same result. I haven’t used either of these, but my neighbor uses soaker hoses, and I hardly ever see any water runoff. The only way I know they’re watering is from the sound of the water passing through their faucet! I’m hoping to invest in a soaker system, possibly next year, when I have a better idea of how the beds will be arranged.
• Collect rainwater for garden watering. Again, I haven’t had the opportunity to try this before. Now that we have a house, it’s a possibility.

Tip #5: Reduce, reuse, recycle. There are numerous opportunitiess to reduce consumption in the garden:

• Apply organic growing techniques to reduce the use of fertilizers, pesticides and other chemicals in the garden.
• Reduce or eliminate areas devoted to lawn and turf.
• Grow some of our own vegetables and fruits to reduce the need to transport them long distances to supermarkets and our homes (the “Victory garden“).
• Select native and heirloom plants and vegetables which we can propagate from year to year instead of having to purchase new seed, plants and bulbs each year.
• Replace gas-powered tools with electric ones, and powered tools with hand tools.

We can reuse materials throughout the garden:

• Broken pots can be used as decorations, and pot shards can be used in the bottoms of pots to control drainage.
• Other artifacts can be reused in the garden as containers and decorations. One of our neighbors has an old radiator spread out as a fan and used as a decoration in their front yard!
• Old, misshapen or imperfect brick and other building materials which can’t be used for construction can be used as pavers, stepping stones, edging and so on in the garden.
• Propagating plants, and giving them away to others, is the ultimate reuse.

Finally, in the garden, composting is the ideal recycling technique. Yard waste such as shrub trimmings and tree prunings can be chipped and shredded. Grass clippings which are not left on the lawn are prized ingredients in compost. Fall leaves, spring cleanup trimmings and summer weeds (which have not gone to seed) go into the compost heap. Kitchen scraps (excluding meat, fat and bones) can be added to the compost as well.
