GGH3701 Assignment 2 Revision
Read the following statement and indicate whether it is TRUE or FALSE: Improvements in
fishing methods result in greater numbers and varieties (sizes and species) of fish being
caught, but fishing in the Southern African region remains sustainable and no overfishing is
taking place. -(correct answer)False ✔ Read the following: Members of a growing settlement
near St. Lucia in South Africa have observed that the estuary has dried up; in fact, the estuary
has been permanently cut off from the sea. Sightings of some endemic estuarine organisms
have also decreased, and it seems that the whole estuary has been lost. Evaluate and select
the primary cause for this observation. 1. Shipping and transportation of goods 2. Periodic
extended droughts 3. Increased freshwater needs owing to coastal developments 4. Increased
freshwater pollution from various settlements -(correct answer)3. Increased freshwater needs
owing to coastal developments ✔ Durban Bay located in the eThekwini municipality has
become physically vulnerable especially after April 2022 primarily due to --- and ---. 1.
increased flooding; accelerated erosion 2. increased agriculture; economic growth 3. mineral
exploration; shipping 4. pollution; decreased rainfall -(correct answer)Increased flooding;
accelerated erosion ✔ Read the following: An urban settlement with surrounding agricultural
areas is located upstream of an estuary. The urban settlement has been growing quite rapidly
and there is pressure on agricultural activities to sustain the growing human population. An
estuary located downstream is consequently negatively affected - the estuary mouth has
closed permanently. Evaluate and select which ONE of the following puts the biggest pressure
on the estuary? 1. Rapid rate of soil erosion 2. Loss of fish species 3. Oil pollution from
shipping 4. Human health issues -(correct answer)1. Rapid rate of soil erosion ✔ Read the
following: Recent reports focused on the assessment of water quality of some of South Africa's
major beaches. The reports have shown a general downward trend in the standard of water
quality especially in regions which have experienced rapid population growth. Evaluate the
given scenario and determine which one of the following is the primary cause for this
observation. 1. Increased shipping and transportation of goods 2. Increased freshwater needs
owing to coastal developments 3. Inadequate sewage works and systems 4. More frequent
floods and periodic extended droughts -(correct answer)3. Inadequate sewage works and
systems ✔ Read the following statement and indicate whether it is TRUE or FALSE: Fertility
determines the age structure and age distribution of a population. -(correct answer)True ✔
Which ONE of the following is commonly used to measure the social and economic impact of
age structures in a specific population? 1. Quality of life 2. Gender differences 3. Age structure
4. Dependency ratio -(correct answer)4. Dependency ratio ✔ Read the following statement
and indicate whether it is TRUE or FALSE: Pro-natalist policies are implemented in countries
that are characterised by ageing populations with a slow natural increase or a natural
decrease. -(correct answer)True ✔ Read the following statement and indicate whether it is
TRUE or FALSE: Population change is described as a function of the three main demographic
processes fertility, mortality and migration which determine the extent to which the size of a
