Presentation Title

A. Introduction to Agrobiodiversity

“All the component of biological diversity associated with food and agriculture, and all components of biological diversity that related to agricultural ecosystems: the variety & variability of animals, plants and microorganisms at the genetic, species and ecosystem levels, which are essential to sustain key functions of the agroecosystem, its structure and processes”

Convention on Biological Diversity (CBD)

Dimension of agrobiodiversity:1.Genetic resources for food and

agriculture2.Components of biodiversity that

support ecosystems functions/services which related with agriculture

3. Abiotic factors4.Socio-economics

Genetic resources:

Food and agriculture encompasses of:

→ plants, animals & microorganism

→ cultivated/domesticated species

→ wild plants and animals

Ecosystem services

Components of biod (organisms) that support ecosystem services in agricultural systems:

→ Pollination

→ Water and nutrient cycles

→ Decomposers

→ Pest and diseases regulation

Abiotic factors

Non-living factor that affect agrobiodiversity:

→ climatic factor

→ chemical factor

Socio-economic & cultural

Socio-economic & cultural dimension included:

→ traditional & local knowledge of

agrobiodiversity

→ cultural factors

→ tourism (ecotourism/agrotourism) with

agricultural landscape

B. Benefits of agrobiodiversity

• Source of food and nutrition (human, livestock & cultivated plants)

• Medicine and health value• Ecosystem services (pollination, food chain)• Genetic resources (plant/animal)• Knowledge (taxonomy)• Economic value• Socio-economic to support livelihood

C. Loss of agrobiodiversity

Habitat loss Deforestation

OvergrazingUnsustainable farming

Population boom

Global warming

C. Loss of agrobiodiversity

Causes & Factors• Environmental pollution• Deforeststation• Overgrazing• Global warming• Climatic change• Overharvest (forest,

fisheries)• Desertification• Ozone depletion• Nature disaster

Impacts• Population decreasing• Soil nutrient deteriorate• Damage to DNA• Influencing animal & plant

growth• Morphology• Biomass accumulation• Effect on reproduction

(reduce reproductive succcess)

• Disruption of food web

D. Best Practices

Enhance agrobiodiversity

Good practices

a. Organic farmingb. Organic trade/productc. Integrated Pest Management IPMd. Seed Bank Systems (SBS)e. Practicing good farming managementf. Species combination enhance productivity and yieldsg. Promote diversity of crops (temporal/spatial)h. Pollinators managementi. Maintenance of wild patches of vegetations in farmingj. Minimal soil disturbancek. Promote a healthy & diverse soil communityl. Integrating livestock in crop production systemm. Application of biological control (natural pest control

strategies)n. Alternative policies for agriculture o. Research and educationp. Market value strategies

SUSTAINABLY

Thank You&

Good Luck
