Abstract
Agriculture is a human productive acitvity which is the cultivation of animas, plants and other products used to sustain life. Agriculture was the key development in the rise of human civilization and. Sustainable agriculture is an important factor which becomes the foundation of the low carbon city development. The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures and technology. Nowaday, the kind of food are developing tend to develop domestic agriculture. However, the food production and recycling agriculture waste we use is not sustainable. The land nutriment will become exhausted because of using in a longtime. Agriculture domestic take a long time, land and cost to treatment. Capital investment for each ingredient individual is expensive. We introduce VAC (VACR) system which food gardenning (V), fish rearing (A) and animal husbandry (C) are intergrated to restrain enviroment impact and crease production efficient. The VAC system is a highly intensive method of small scale farming that makes optimal use of land, water and solar energy, achieving high economic efficiency for low capital investment. VAC leads to the creation of pleasant, peaceful landscapes, tree planting is encouraged with no artificial chemicals are used and maximum amount agriculture pollution by creating biogas.

1. Introduction
Agriculture plays an important role in continuous human life and develop civilization. Agriculture is supplying food to meet requirement of different social classes, supplying the primary materials to other economy sectors, supplying the capital for other economy sectors (industry), marketing for other economy sectors, supplying the human force to other economy sectors and creating the good enviroment. This will become foundation of all city. However, it affect enviroment which is one off the largest survice of greenhouse gases, waste a lot of domestic in the enviroment. It also change the land form and make climate change also. Therefore we have to consider the use critical water, land, and ecosystem and recycling waste and tend to sustainable agriculture. Sustainable agriculture has been defined as an integrated system of plant and animal production practices having a site – specific application that will last over the long term: satisfy human food and fiber needs, enhance enviromental quality and the natural resource base upon which the agricultural economy depends, make the most efficient use of non-renewable resources and on-farm resources and intergrate, where appropriate, natural biological cycles and controls, sustain the economic viability of farm operations and enhance the quality of life for farmers and society as a whole. In order to built low carbon city, the first thing we need is to create sustainable agriculture. So, we introduce the VAC system is production methods appication leading to increased income, improved standards of living and reduce enviroment impact.

1.1. Background of VAC system.
In Vietnam, a country of small-scale farmers, an integrated farming system called VAC rapidly gains interets which develop from traditional gardening in the fertile Red River Dalta. In 1986, due to decades of war Vietnamese’s agriculture was seriously set back. Food intake was inadequate, espectially animal protein. Many programs were implemented in Vietnam to improve the food intake and nutritional status of the people, and escpecially the intake of animal sourcce foods. The VAC system is a traditional type of farming for Vietnamese people. The aim of VAC is to provide diversified agricultural products to meet the complex nutritrional demands of man....
