Q & A
What are natural resources?
-Natural resources refer to materials or substances that exist in the natural environment and are valuable to humans and other organisms.
How are natural resources classified based on their ability to replenish?
-Natural resources are classified into two categories: renewable and nonrenewable, based on their ability to replenish over time.
What are nonrenewable natural resources and can you provide an example?
-Nonrenewable natural resources are finite resources that cannot be replenished within a human time frame or are replenished extremely slow. Examples include fossil fuels like petrol, crude oil, and coal, as well as minerals like gold, tin, iron, and nuclear energy.
What defines renewable natural resources?
-Renewable natural resources are those that can replenish naturally or through human intervention within a relatively short period. Examples include plants, animals, forests, fish, wildlife, water bodies, air, wind, and sunlight.
How do forests contribute to the environment as a renewable natural resource?
-Forests contribute by regenerating, supporting biodiversity, sequestering carbon, providing ecosystem services, and serving as a source of livelihood for people living around or outside the forest ecosystem.
What is the definition of a forest according to the FAO and UN?
-According to the FAO and UN, a forest is an area of land spanning more than 0.05 hectares with tree cover or equivalent stocking level of more than 10%, with trees capable of reaching a minimum height of 2 to 5 meters at maturity.
What is the definition of forestry?
-Forestry is defined as the art, science, and practice of studying and managing forested land, plantations, and associated natural resources such as water and wasteland for timber and non-timber resources, conservation, recreation, and other purposes.
What is the definition of wildlife according to the Nigerian Conservation Foundation?
-According to the Nigerian Conservation Foundation, wildlife refers to all living things, including plants, invertebrates, and vertebrate animals outside the direct control of man, which are noncultivated or non-domesticated.
Why are forests important for biodiversity conservation?
-Forests are important for biodiversity conservation because they house a wide range of wildlife, from lower to higher organisms, providing habitats for various species and supporting the overall balance of ecosystems.
How do forests help in climate regulation and carbon sequestration?
-Forests help in climate regulation by sequestering carbon dioxide, a greenhouse gas, and releasing oxygen. They also play a role in maintaining the water cycle and preventing erosion, which contributes to overall climate stability.
What are some of the ecosystem services provided by forests?
-Forests provide various ecosystem services including food and timber production, habitat for wildlife, oxygen provision, carbon sequestration, climate regulation, water cycle regulation, erosion control, nutrient cycling, and air and water quality improvement.
What are some misconceptions people might have about forests?
-Some misconceptions about forests include viewing them as impediments to development, homes for the dead or evil spirits, signs of underdevelopment or backwardness, places of fear and mystery, or habitats for dangerous animals.

🌿 Understanding Renewable and Non-Renewable Natural Resources
Dr. Unuku introduces the topic of renewable natural resources in the context of forest resource management. He explains that natural resources are materials found in nature that are valuable to humans and other organisms. These are divided into renewable and non-renewable categories based on their ability to replenish. Non-renewable resources, such as fossil fuels, minerals, and nuclear energy, are finite and replenish very slowly. In contrast, renewable resources like plants, animals, water, air, wind, solar energy, and soil can regenerate naturally or through human intervention. The lecture focuses on renewable resources, emphasizing their importance in various environmental and economic aspects.
🌳 The Role and Definition of Forests in Renewable Natural Resources
In this paragraph, Dr. Unuku delves into the concept of forests as renewable natural resources, discussing their ability to regenerate and support biodiversity, sequester carbon, and provide ecosystem services. He addresses various perceptions of forests, ranging from impediments to development to habitats for wildlife. The definition of a forest according to FAO and UN standards is presented, emphasizing areas covered chiefly with trees. Forestry is defined as the practice of managing forested lands and associated resources for multiple purposes, including timber and non-timber products. Wildlife is also discussed, highlighting its broader definition that includes non-domesticated plants, animals, and other organisms.
🌳🐾 The Importance of Forests and Wildlife in Ecosystems
Dr. Unuku concludes the lecture by highlighting the multifaceted importance of forests and wildlife. Forests are described as providers of food, timber, and habitats for a wide range of wildlife. They play a crucial role in biodiversity conservation, carbon sequestration, climate regulation, and oxygen production. Forests also contribute to water cycle regulation, erosion control, soil protection, and nutrient cycling. Moreover, they improve air and water quality and offer recreational, cultural, religious, and spiritual values. The lecture aims to provide a clear understanding of the distinctions between forests, forestry, wildlife, and the broader categories of natural resources, both renewable and non-renewable.

Transcripts
welcome I am Dr
unuku in this video we're going to be
covering understanding renewable natural
resources under the c
f
211 introduction to Forest resources
management I would want you to sit tight
and listen cas carefully as we go
gradually okay let me share my
slide thank
you like I mentioned
before we will be talking on the topic
understanding renewable natural
resources and to start
with let's understand what natural
resources
are natural resources refers to
materials or substances that exist in
the natural environment and are valuable
to human and other organism so
everything that occurs naturally are
tered as natural
resources based on the ability to
replenish over time they are classified
into two renewable and
nonrenewable uh natural resources
let's start with the nonrenewable
natural resources non-renewable natural
resources are finite resources that
cannot be replenished
within a human time frame or are
replenished extremely slow so these
resources that cannot be replenished or
replenish extremely slow are Ed as
nonrenewable natural resources
for instance our fil fuel like our
petrol our crude oil our coal and so on
fossil fuels are example of uh
non-renewable natural
resources for instance our minerals like
our gold tein iron and so on and so
forth are also example of non-renewable
natural res Source some of our energy
source like the nuclear energy are also
termed
as example of
nonrenewable Natural Energy Source uh
energies now let's talk about natural
renewable natural resources which is a
focus for this particular uh
lecture renewable natural resources are
resources that can replenish
naturally or through human intervention
within relative short
period for instance our plant and animal
such as our forest you know
trees um
Fish Wildlife these are examples of uh
renewable natural resources they are
renewable natural resources because they
can regenerate thems they can regenerate
either for instance in the terms of the
trees they can regenerate either
artificially or naturally okay but of
course their ability to regenerate
classify them under the renewable
natural resources like our fish our
wildlife of course
water which includes our Rivers our
Lakes underground water they are also Al
ter as renewable natural resources air
and
wind used to generate um wind energy you
know they are also renewable natural
resources because they renew
naturally our solar energy uh which the
main source is from the
sunlight is a renewable energy it
doesn't finish it replenishes
naturally then we talk of soil which is
essential for Agriculture and Forestry
it's also a renewable natural resource
because it
renews now let's look at forests as
renewable natural resource our forests
like I said wildlife and
fishes can continue to reproduce and
regenerate their population as long as
environmental conditions remain
favorable and uh an adequate seed source
or breeding stock is
maintained looking at Forest as a
renewable natural
resources some of the reasons that one
it
regenerates it supports
biodiversity it sequences carbon it
provide ecosystem Services uh and it's
also
source of livelihood especially for
people living around uh the forest and
even people outside the forest
ecosystem now let's bring it back home
to forestry and
Wildlife what is uh a
forest when we talk of forest what is a
forest forest means different things to
different people you know when you talk
about about
Forest some people in their mind the
first thing that comes to their mind is
impediment for development anything
Forest is something that stops
development something that hinders
development some people immediately you
mention Forest the the first thing that
comes to their mind is that Forest is a
home for the dead is a home for evil
spirit it's uh any kind of diabolic
things are attributed to the forest and
of course these are might another thing
forest mean to other people is when you
mention Forest they see it as a sign of
underdevelopment as
backwardness some people see Forest as a
place of fear and mystery some people
see Forest as habitat for dangerous
animals and some people associate Forest
to
negativity however according to ORD
dictionary Forest is a large area
covered chiefly with
trees and undergrowth according to
FAO and un
Forest they say is an area of land
spanning more than 0.05 hectar
with three crank cover or equivalent
stocking level of more than 10 % with
trees with the potential of reaching
minimum height of 2 to 5 m at maturity
in2 this is what FAO Define
forest
as and of course we got the word
forestry from forest which uh is defined
as the art science and practice of
studying and managing forested land
plantations and Associated natural
resources such as
water and uh Wasteland harvesting Timber
and non Timber resources conservation
Recreation and other purposes of course
we understand that the term
forestry has been defined severally by
different authors but we're going to
stick to
this particular
definition because of this uh lecture
forestry also involves the production
which is planting and
maintenance the distribution and
consumption of forest products and
services and on the other hand Wildlife
this refers to all non deticated plants
and animal other than uh and other
organisms when you talk of wildli before
now people just attribute wildli to only
animal but I'm here to tell you today
that Wildlife is all non-domesticated
plants animals and other
organisms according to Nigerian
conservation foundation in
1965 uh the defined Wildlife as all
living things
plants invertebrate and vertebrate
animal outside the direct control of man
I want you to underline the word uh
Direct control of man outside Direct
Control of man that is noncultivated
plants or non demestic animal so haven't
understood the difference or the
definition of Forestry and
Wildlife let's now look at the
importance of forests
Forest uh provides food and uh timber
for us as hum it provide food and Timber
it's also habitat for wildlife Forest
houses several Wildlife from the lower
ones to a higher ones provide home for
all wi and for large range of wild
animals including beds including mammals
including amphibians and so on and so
forth uh Forest
also uh provide Center for for
biodiversity conservation Forest
conserve
biodiversity carbon sequestration and
climate regulation Forest is also
important because um it helps in carbon
sequestration and uh regulate our
climates Forest provides oxygen that we
taken and also in return takes in the
carbon dioxide which is harmful to the
environment uh Forest also help in water
cycle regulation stroke erosion control
uh Forest
uh provide erosion control both in terms
of wind erosion and water erosion Forest
protects our soil and uh helps in the
nutrient
cycling also Forest provide air and
water quality improvement Forest also
provides us with Recreation and C
values religious and spiritual values
and so on and so forth so the list goes
on and on and on and of course uh this
lecture with uh this lecture I believe
that you can tell us what Forest is you
can differentiate between Forest
forestry and uh Wildlife you can also
differentiate between natural resources
and uh you can differentiate between
renewable and nonrenewable natural
resources okay ladies and
gentlemen thank you for listening and um
we're going to continue in the next
video thank you and see you next time
