Briones Park

sweet hills

The December day was gray, with a clear wish to rain. The expanse of Briones Park, peacefully empty, was exhilarating for the young woman recently arrived from Milan (that is, me). While people were rushing hither and thither to get all the Christmas chores done, we were luxuriating amid softly undulating hills studded with stately oaks. 

My first walk in Briones Park occurred during my first visit to California 20 years ago. I have been back countless times. I have walked on pretty much all its trails (and all around nearby Briones Reservoir). My first photographic project had the Park as subject. I love Briones Park, jewel of the East Bay Regional Park District:

With its rolling, grassy hills and secluded, shady canyons, Briones is a secret wilderness surrounded by the towns of central Contra Costa County. Although the park is close to Lafayette, Walnut Creek, Pleasant Hill, Concord, and Martinez, there are peaks within it from which you can see only park and watershed lands for miles in every direction.

The photo above shows the classic landscape of Briones Park. As the dry season progresses, the grass will dry making the dark green oaks stand out even more.

on the Briones Crest Trail

After a long stretch in the open, it is nice to enter a short tunnel where the sunlight, filtering through the trees, creates a kind of marbling on the ground. Uphill from this spot, I once met a coyote. Neither of us was particularly excited about the encounter, so we decided to go our separate ways with just a nod as salute.

the sky is the limit

My recent walk in Briones Park occurred on a day where I needed help quieting the turmoil in my mind. I took this image of a path carved on the side of a hill as an invitation to forge ahead.

cattle grazing

Humans and coyotes are not the only creatures sharing the park space. Cattle grazing occurs in Briones Park year round. This page explains how grazing animals benefit this and the other parks that are part of the East Bay Park Regional District:

Livestock grazing utilizing cattle, sheep and goats is used as a vegetation management tool to maintain and improve habitat conditions for resident plants and animals and to prevent wildfires. [source]

A moment of rest

There are various ways of enjoying the natural beauty of the park: hiking, biking, horse-back riding, or resting with your back on the grass and your eyes to the sky. 

I invite you to celebrate Earth Day with a walk in a park (last year, we were in Yosemite National Park), though, of course, every day it Earth Day.

Earth Day was started in 1970 by US Senator Gaylord Nelson. Celebrated on April 22nd, Earth Day reminds us that we share responsibility for the health (salute) of our beautiful planet (pianeta).

There are a few thoughts I have been meaning to share with you for some time and Earth Day (or thereabouts) sounds like the appropriate time. In recent years, I have become particularly interested in food waste (spreco alimentare) and food scrap recycling.

Food waste includes uneaten food and food preparation scraps from residences or households, commercial establishments like restaurants, grocery stores, cafeterias and industrial sources. (source: Environmental Protection Agency)

The amount of food that goes to waste in the US every year is staggering:

The US generates more than 34 million tons of food waste each year. Paper is the only material category where we generate more waste, but we also recycle more. Food waste is more than 14 percent of the total municipal solid waste [MSW] stream. Less than three percent of the 34 million tons of food waste generated in 2009 was recovered and recycled. The rest —33 million tons— was thrown away. Food waste now represents the single largest component of MSW reaching landfills and incinerators. (source: EPA)

Not only does this wasted valuable resource have huge economic impacts, it also has huge and immediate environmental impacts. When food is disposed in a landfill it quickly rots and becomes a significant source of methane — a potent greenhouse gas with 21 times the global warming potential of carbon dioxide. Landfills are a major source of human-related methane in the United States, accounting for more than 20 percent of all methane emissions. (source: EPA)

After having stated the problem, let’s talk about ways to address it. Another page on the EPA’s website shows the food waste recovery hierarchy and yet another one suggests ways for households to address the food waste problem. I really like the subtitle of this last page: Think – Reduce, Reuse, Recycle (compost). Thinking about what we are doing allows us to become aware of where waste occurs. Then, we can implement measures aimed at minimizing waste.

For example, food waste can occur when we purchase more food than we consume, in particular perishable items like fresh vegetables. We can do a lot to help our planet by paying special attention to our shopping cart or basket and to all the drawers of our fridge plus those nooks and crannies where food has a tendency to hide and condemn itself to oblivion. Precious resources went into the production of that food: when we throw it, those resources become wasted. The way to minimize the environmental impact of food that, for various reasons, must be discarded is recycling, i.e., composting.

If you are interested in learning more, I have written two articles on the subject of food waste and of food scrap recycling: one is here (on page 45) and one is here (pdf). Wasted Food is a blog totally dedicated to this important topic. This recent post provides cogent reasons for why food waste matters.

Readers in the UK may have heard about plans to review current food labeling practices to clarify the labels and reduce waste. Here is a commentary on the announcement.

Unavoidable food waste can be turned not only into natural fertilizer (compost), but also into energy: this happens in facilities called anaerobic digesters, one of which is in Oakland, CA.

One more thing: take a look at the site Love Food Hate Waste.
