IMPORTANCE OF BIODIVERSITYFood

FISH comprises 10% of protein intake globally and 50-60% that of Filipinos.

Food for all living organisms not just for man!

> 90% calorie intake globally comes from 80 PLANT SPECIES

IMPORTANCE OF BIODIVERSITYMedicines

•80% of the world’s population use plants as 1° source of medicine

•30% of all pharma medicines are developed from plants and animals

Fuel, timber, fiber and other resourcesMost houses, furniture and even

many clothes are made from natural products, including wood, oils, resins, waxes, gums and fibers.The cocoons of silk worms are the basis of the valuable, centuries-old Asian silk-making industry.

The Physical Environment

Country’s productivity

* "Declining" productivity of the country's agricultural lands and fisheries.

• These areas become increasingly degraded and pushed beyond their capacity to produce

• Cause: Rapid forest loss has eliminated habitat for unique and threatened plant and animal species; it has also left large tracts of land in the Philippines vulnerable to soil erosion

*The loss of nutrient rich soil reduces crop yields and contributes to the expanded use of chemical fertilizers - a practice that can, in turn, pollute water sources.

• Rivers and streams also carry eroded soil to the coasts, where it interferes with fish nursery areas.

• * Soil runoff into fish breeding and nursery areas is one of several factors leading to the overall decline in productivity of fisheries in the Philippines

Consequences Food insecurity. The lack of a stable and reliable

food supply contributes to poor nutritional status for many Filipinos, especially for children: Approximately 28 percent of children under 5 are underweight (DOH Report, 2006)

Food insecurity also contributes to increases in environmentally destructive practices such as slash-and-burn agriculture ("kaingin" farming) or the use of dynamite to increase short-term fish catches.

. * In 1970, 32 percent of the country's population lived in urban areas. * Today, 48 percent is crowded into cities, where housing and infrastructure struggle to keep pace with the growing numbers.

• Overcrowding and insufficient housing can be particularly detrimental to children: Studies have suggested that infant mortality rates in Manila's slums are three times higher than in non-slum areas

Water crisis is not far behind: Access to clean and adequate water is an acute seasonal problem in Metro Manila, Central Luzon, Southern Tagalog, and Central Visayas.

Government monitoring data showed that up to 58 percent of the country's water ground is contaminated with coliform bacteria, causing such diseases as diarrhea, cholera, dysentery, and hepatitis A.

studies show that there is a steady 30-50% drop in the levels of the country’s water sources for the past 20 years or an average drop of 1 meter/year

While on the average, the atmosphere’s moisture is renewed every 8 days, stream water every 16 days, soil moisture annually, swamp water in 5 years, lake water in 17 years, groundwater renews only after 1,400 years.
