Sustainable Agriculture- What is it? An indepth look.

Okay, so all this talk about green and sustainability... leads to wait- what is sustainable agriculture again? So, this will provide answers and sources I found to those answers :) Happy Reading !

What is Sustainable agriculture?
From http://www.sarep.ucdavis.edu/concept.htm

"Sustainable agriculture integrates three main goals--environmental health, economic profitability, and social and economic equity."

Basically it looks at the health of people, health of the enviroment, health of economic standpoint-- that people are not going completely broke and aren't socially a lower class due to sustainable agriculture.

It also looks at things both big and small- from the single farmer to the nation to the world. It also looks at the impact actions have on the environment- in various ways- in the air, in the water, in the soil quality, in plant quality and what is produced. Also, the impact on wildlife, and energy is also taken into account.

Its goal is an healthy earth.


What are the Considerations to Sustainable agriculture?

- Environment, Environment, Environment. If it evolved there, IT SHOULD BE THERE! *ahem*
- Climate -- this tells you what is and isn't sustainable in terms of water needs,& temperature. A plant that gets to cold/to hot, or not enough rain/ too much rain dies. That's not very sustainable !
-soil type -- plants are picky about their soil, as much as humans are about their food.
- Diversify! Different is good. It protects, it invites more natural processes, it can do all sorts of neat things. And, if one crop fails, another may do better, so it isn't instant disaster.
-Wildstock and Crops together...it provides another source of food, fertilizer, will eat failed crops, can keep away other wildlife, and protect the farmer against complete failure of the farm.

inputs-- what a person puts in work wise and chemical wise into the soil.

Another quote
"Growers frequently ask if synthetic chemicals are appropriate in a sustainable farming system. Sustainable approaches are those that are the least toxic and least energy
intensive, and yet maintain productivity and profitability. Preventive strategies and
other alternatives should be employed before using chemical inputs from any source.
However, there may be situations where the use of synthetic chemicals would be more
"sustainable" than a strictly nonchemical approach or an approach using toxic
"organic" chemicals. For example, one grape grower switched from tillage to a
few applications of a broad spectrum contact herbicide in the vine row. This approach may
use less energy and may compact the soil less than numerous pa**** with a cultivator or
mower."

This article also takes into account farmer's lifestyle choices... sustainability may not work if one wants to make lots of money, it may not work for someone who wants more free time.


There are also animal production practices which can include the following: animal health, feed, breeding, type, area animal is confined to, the above mentioned sustainability characteristics, and more.

Also Values, government policy, land use, and other things can effect what is sustainable.

A Quote-
"6) National Campaign for Sustainable Agriculture
(http://www.sustainableagriculture.net)
food and agricultural systems and rural communities that are healthy,
“. . .
environmentally sound, profitable, humane and just
a) More independent farmers and ranchers producing good food, making a
good living and protecting the environment;
b) Thriving communities connected through sustainable food production,
processing and distribution systems based on fair and open markets;
c) Dignified livelihoods and living wages for all workers in the farm and food
sector;
d) A safe, secure food supply;
e) Access for everyone in our society to nutritious, healthful and affordable
food;
f) Farming and ranching practices that produce quality food and other
products, while preserving open space, abundant wildlife, and other forms
of biodiversity."

So sustainable argiculture is a very complicated thing! It requires knowledge about climate, land use, plant preferences, human preferences, wildlife and plant interaction and probably a little bit of luck. They've got so much on this...so much going into and so much education required. No wonder it can't just happen... its a major process analysing thing...especially if natural habitat has been destroyed.

Next Post- tomorrow (most likely) Case Studies: where has it been successful, and where has it failed?

Sustainability also should entail a continuity of skills--"passing the torch" to the next generations who will share the Earth we inhabit, since our tomorrows will be their "today." Sustainable development can also embrace industrial and technological advancements, since carbon emissions and other pollutants/by-products of development have c**ulative, as well as immediate, effects on the environment, our agriculture, our energy, our source of potable water, habitable (for sea-life) oceans, breathable air.
Universal Human Rights (safety, security, access to sustainable sources of food, renewable energy, fresh water, air, etc) and the United Nations' Millennium Development Goals (End poverty and hunger, Universal Education, Gender Equality, Child Health, Maternal Health, Combat HIV/AIDS, Environmental Sustainability, Global Partnership) are all receiving increased attention, consideration, and participation to find solutions (http://www.un.org/millenniumgoals/ ),
There are blog posts, and information sites linked there, too, for more information.
Good knowledge share, Crystal, and thank you for the spark, too (sorry I can only vote one point, though)! I look forward to reading more when you have time.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ***tances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
