WHAT IS BUILDING INTEGRATED AGRICULTURE (BIA)?Practice of locating farming systems on and in mixed use buildings.

TYPES OF BIA● Hydroponics

● Aquaponics

● Community Gardens

● Container Farms

● Green Roofs

● Permaculture

● Vertical Farms

HYDROPONICSMethod of growing plants that uses water with mineral

nutrient solutions, instead of soil.

Precise management is necessary: careful measurement of nutrient concentrations and adjustment of flow rates.

It uses less water compared to soil gardening.

Leads to water conservation due to reusing water multiple times.

AQUAPONICSIt is a combination of both recirculating hydroponics and aquaculture

(Fish production).

Offers a balanced nutrient cycle because the waste produced by fish is utilised as a beneficial fertilizer to grow plants.

There is no need to discard or change water, since the water is completely recycled.

The nutrients solution is used in a recirculating hydroponic system. The nitrates are removed from the system by plants.

COMMUNITY GARDENPlaces where people share lands to grow

food.

Improve the local environment.

It is possible to utilise renewable technologies, such as greywater systems.

The garden could use water harvested from rain.

CONTAINER FARMSFarm inside a modified shipping

container.

It could be used in all environments and climates, once it is remoted controlled.

Utilises the Hydroponic System to crop production.

GREEN ROOFSVegetation are planted in a roof surface over a

waterproof membrane.

It reduces and slows the stormwater runoff.

Used to absorb rainwater.

The soil filters pollutants and heavy metals out of rainwater.

PERMACULTUREIt is a design system including several

methods, such as agriculture, water harvesting, waste management, aquaculture.

It integrates food supply and settlements with water harvested from roof areas.

The wastes are returned to the soil and plants via compost or mulch.

VERTICAL FARMS Production of food in vertical surfaces or vertically stacked layers.

Could be indoor or outside farms.

It may incorporates water elements, such as ponds and fish.

Green walls could be utilised as part of water treatment system.

IN SUMMARY, BIA..Is an environmentally sustainable method for urban

food production;

Decreases environmental footprint, transportation costs;

Enhances food security;

Conserves water;

Combates global warming.
