Biodiversity is the basis of

agriculture.Of the 27,000 species of higher plants,

About 7,000 species of plants arecultivated in agriculture.

Today only 30 species of crops onlycultivated , In that wheat, rice and maize

alone providing about half of the food allover the world.

(FAO)These figures shows that, how many no ofspecies we have lost, how the food webhas broken and the role of these species

in the ecosystem ,will not be

substituted by any of us

Agriculture depends on healthyecosystems to provide services thatinclude nutrient and waste recycling,

pollination from insects, soil erosioncontrol, and clean water.

Clearing of native vegetation, doingmonoculture causes huge geneticerosion& loss of Natural resources

Components of Biodiversity

cum Agro forestry modelfarm

Bamboo- used for variouspurpose & timber value

Glyricidia- N fixing tree used forGreen Manure & also fodderpurpose

Pathimugam- wood used fornatural dye Extraction & water

purification.

Components of Biodiversity - Banana, sapota, lemon

Selection of trees in thebiodiversity farm should give AdaptabilityProductivitySustainabilityin terms of money and fertility ofthe soil

Pollination is one of the most valuable

services provided by ecosystems.Pollinators like flies, moths,butterflies, wasps, beetles, bats, andhumming birds, bees are the principal

agents pollination.Pollinators help maintain the diversityof ecosystems by facilitating thereproduction of many plant species.

The fundamental component of theagricultural system is the soil.

Soil is one of the most diverse habitats onearth and contains diverse living organisms,including microorganisms such as bacteriaand fungi, and macro-organisms such as

worms, mites, ants, and spiders.

Mulching of crop waste andresidue


15/28

Soil organisms provideessential resources forthe sustainablefunctioning of

agricultural ecosystems

Live mulch inside

the farm enrichesthe organic mattercontent / humus inthe soil

Organic matter isthe key componenof the soil


16/28

One square metre of Soil may contain more than1000 species of invertebrates and the diversityof microorganisms .

We having 40 species of plants & Tree species inRavis farm.

To create this Biodiversity in our farm, everythingshould be left it as such and effective rainwater

harvesting as like in forest.

Decomposition of

Banana crop wastesby the action of

Termites

Banana is the crop ,whichgives high biomass, for easy& quick decomposition ,dueto its succulent plant partsand it is a good source formicrobes and it is a good

feed for earthworm

multiplication


18/28

Soil organisms like earthworms, termites and

other burrowing organisms mix the upperlayers, redistributing nutrients and increasing

soil aeration by opening the soil micro &macro pores ,it will also increases water

infiltration

Benefits of Biodiversity richAgroforestry

Environmental Benefits Needs very less water (i.e) only 1/3 quantity is

sufficient for this farming.

Regulation of pests and diseases;

More efficient recycling of nutrients by deeprooted trees

Better protection of ecological systems

improvement of micro climate inside the farm

Improvement of soil organic matter

Maintenance of soil fertility and biota; and

Pollination by bees and other wildlife etc.,


27/28

Economic benefits

No tillage activities so man power requires

only for collection of Produce.No incidence of total crop failure, and

A sustainable income pays way for self

reliant farming.Weekly income from fruits & vegetables-

Rs.1500 /-

Bimonthly Income from coconut Cattle &Goat -Rs. 14 to 16,000/-

Timber value of the trees in 6 years period-Rs.4,00000/-
