GGH3701 Assignment 2 Revision 2025

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 Ans-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 Ans-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 Ans-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 Ans-1. Rapid rate of soil erosion Read the following: GGH3701 GGH3701 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 Ans-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 Ans 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 Ans-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 Ans-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 particular population changes over time. - Correct Ans-True Read the following statement and indicate whether it is TRUE or FALSE: Birth, death and migration are all three biological events which only occur once in every person's lifetime, having a similar influence on population change. - Correct Ans-False Read the following: South Africa has been experiencing an increase in the number of people migrating from rural areas. This has led to the development of numerous informal settlements and widespread environmental degradation. GGH3701 GGH3701 You have been requested to provide suitable recommendations to address the given issue. Which ONE of the following would you recommend as the most applicable to this scenario? 1. Financial penalties 2. Pro-natalist policy 3. Anti-natalist policy 4. Redistribution policy - Correct Ans-4. Redistribution policy Read the following statement and indicate whether it is TRUE or FALSE: The physical environment may influence the location and type of economic activities, but it does not determine them. - Correct Ans-True Read the following statement and indicate whether it is TRUE or FALSE: The economic decisions taken by some Southern African countries in relation to the Paris Agreement, such as modifying the content of greenhouse gases of the atmosphere, will not have consequences for biodiversity, land use, ecosystems and human health. - Correct Ans-False Read the following statement and indicate whether it is TRUE or FALSE: Management can be selected as an applicable and efficient interventions in areas with high environmental resource value and where the population densities are of such a nature that it is negatively affecting the natural environment however no permanent damage has yet taken place. - Correct Ans-True Read the following statement and indicate whether it is TRUE or FALSE: Interrelationships only exist between the environment, population and economic activities. These factors are consequently all independent meaning that past and current policies and political reforms has had minor effects - Correct Ans-False Read the following statement and indicate whether it is TRUE or FALSE: Political reforms which are supported by financial and human resources are classified as reconstruction interventions. - Correct Ans-False Read the following scenario: An area in Botswana is characterised by natural resources that have not yet been degraded by high population densities. This area has been identified by the government and need an intervention that would preserve its natural resources. Evaluate the given scenario and determine which one of the following interventions should be chosen to preserve the natural resources of the area. 1. Reconstruction 2. Mitigation 3. Conservation GGH3701 GGH3701 4. Management - Correct Ans-3. Conservation
