CSA participants in New Hampshire
Community Supported Agriculture consists of a community of individuals who pledge support to a farm operation so that the farmland becomes, either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits of food production. Typically, members or "share-holders" of the farm or garden pledge in advance to cover the anticipated costs of the farm operation and farmer's salary. In return, they receive shares in the farm's bounty throughout the growing season, as well as satisfaction gained from reconnecting to the land and participating directly in food production. Members also share in the risks of farming, including poor harvests due to unfavorable weather or pests. By direct sales to community members, who have provided the farmer with working capital in advance, growers receive better prices for their crops, gain some financial security, and are relieved of much of the burden of marketing.

It is a form of local support for agriculture. Subscribers pre-pay a farmer to grow the desired produce. Sometimes the farmer will select what is to be grown, sometimes the buyer selects what they want to buy, more often it is a cooperative arrangement between the two parties.

Sharing knowledge to build rich, sustainable lives.
Appropedia is the site for collaborative solutions in sustainability, poverty reduction and international development through the use of sound principles and appropriate technology and the sharing of wisdom and project information. It is a wiki, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors.

Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions. For more about our motivation, see Appropedia:Mission.

To create a new project page, first browse the project articles and subcategories below for examples and check for possible collaboration opportunities, such as articles similar to what you're considering writing. If you are looking for ideas for your own project, check out our suggested projects. It is highly encouraged to tag your projects with their status -- you can do this with a few templates. Be Bold!
