lu2 nature of resource and allocation
renewable resource
biomass energy, hydropower, geothermal power, wind and solar energy
energy which is generated from natural resources and can be generated again and again as and when required
non renewable
natural resource that cannot be regrown at a scale to its consumption
cannot be generated within a short span of time
examples
fossil fuels
natural gas
oil
coal
importance of non/renewable resources
provide the essential ecological services
definition = the benefits people obtain from ecosystems
types of ecological services
provisional
food
intro
main source - plants, animals, fish
agriculture
provides the genetic mmaterials for food and af=gricultural crops
wild animals
healthy growth and pollination of plants
by brids, bats, insects
agriculture and food security
rice is important in malaysia
FAO has estimated ~10k-50k plant sp are edible
only 200sp are
cultivated
as food
many more sp that can be commercialised
domestic animals
improved by crossbreeding wild relatives
conservation programmes
important by providing broad gene pool and genetic improvement for future food security
wild cattle of malsyia
fisheries and food security
mangrove swamp
feeding and nursery ground for fisheries
being habitats of several of our important comercial fishes and shrimps
plays signifivant role in national economy
three main subsectors
marine capture fisheries
aquaculture
inland fisheries
fishery department figures
produces about 1.5 m of fisheries products anually - 85% are marine capture fish, the rest of the agriculture production
total value of fisheries output is >1.5b/year
fibre
fuel
wood
freshwater
essential resouces
WATER
utilisation
my's water is entirely derived from surface water resources
98%
rivers
reservoirs
2%
groundwater
my spends most of its valueable water on irrigation and industrial and domestic purposes
non-comsumptive
hydropower
navigation
recreational activities
forest products
major national economic importance
timber was a major income earner in malaysia in the 1960s-1990s and plays crictical role in economic development
non timber
rattan
agarwood
gums
resins
edible oils
medicines and food
regulative
climate regulation
forest are the stabilizing force of the climate - lay important role in regulation of the ecosystems and carbon dioxide cycle
~2.6b tonnes of CO2 is absorbed by forests every year
forests provides $75-100b/year in goods and services - clean water and healthy soils
“Fast-growing oceanic jungles of
kelp and other macroalgae are
highly efficient at storing carbon”.
“..research has shown that adding
seaweed to livestock feed can
reduce potent methane emissions
from the burps of cows and other
grazing livestock—a significant
source of global greenhouse
gases—by as much as 70 percent
disease control
water purification
supporting
nutrient cycling
a continuous process in which dead plant material decomposes and provides nutrients to the soil that are absorbed by plant roots, so that plants can grow
farming
cultural
traditional knowledge
FAO estimated 3/4 of prescription drugs manufactured today are based on the traditional knowledge of the local communities or indigineous people
plants and animals are the basis of most traditional medicines
hempedu bumi
dengue treatment
bitter melon
white leadtree
tourism
recreational diving - depends on the diversity of the coral reef
sipadan, layang-layang
mulu national park
UNESCO world heritage sites with biodiversity of global significance
kinabalu national park
taman negara national park anually draws >80k tourists
plants, animlas and mirobes
provide food
medicine
++products for daily basis
helps sustain the economy
