This paper is a review of the impacts of climate change on fisheries in Zambia. Climate change has been having a remarkable impact in several areas. One of the areas is the area of fisheries and aquaculture. The author reviewed many papers written on the topic of aquaculture and fisheries. Zambia, like many other countries, have been facing many impacts from climate change. The paper aims to provide some suggestions on the solutions to combat climate change impacts.
The variability in climate has caused a lot of problems to both marine and fresh water aquatic ecosystems. These problems have spread to terrestrial ecosystems posing problems to fresh water aquaculture, forest ecosystems as well as agricultural ecosystems. Climate change has thus become a regional and global problem causing concerns over the preservation of these ecosystems for future generations. One of the results of climate change is global warming. It has been predicted that between 2010 and 2070 the world surface temperatures will increase by between 10 C to 2.70 C. This impact will affect the world economically, socially, environmentally and ecologically. This paper reviews works by experts as well as national and international organizations on impacts of climate change on aquaculture and fisheries in Zambia. It seeks to investigate the methods of mitigating and adapting to climate change which the Zambian government and stake holder organizations have put in place and may be able to put in place. Further the paper assesses the hindrances to adaptation and mitigation of climate change impacts in Zambia.

Excerpt from the Book
Increase in average temperature
All marine and aquatic invertebrates (molluscs, crustaceans, worms etc.) and fish are poikilotherms; their internal temperature varies directly with that of their environment. This makes them very sensitive to changes in the temperature of their surrounding environment. When changes do occur they move to areas where the external temperature allows them to regain their preferred internal temperatures. Therefore the tendency which has been predicted is that the cooler regions will gain while the tropics , like the Zambezi, will suffer losses of upto 40% (Cheung et al., 2010). This is the species migration effect of increases in temperature.
Another impact of changes in average temperature is reported by Walther et al., (2002). This involves recruitment which is reduced due to higher temperatures in the aquatic environments. Eaterling et al., (2007) also reported that some stocks may fall below sustainable levels due to alterations in temperature even if the stocks are subjected to the same fishing effort. Where fish continue to inhabit waring bodies of water the increase in temperature will increase their metabolic rate hence slowing growth and consequently reducing maximum species length and weight.
Summary of Chapters
INTRODUCTION: Provides an overview of Zambia's geography, the state of its fisheries sector, and the current production statistics versus domestic demand.
POTENTIAL IMPACTS OF CLIMATE CHANGE ON FISHERIES AND AQUACULTURE IN SUB-SAHARAN AFRICA: Discusses the vulnerability of aquatic ecosystems in Africa to temperature fluctuations, hydrological changes, and shifts in species distribution.
CLIMATE CHANGE ADAPTATION AND MITIGATION STRATEGIES: Reviews the existing policy framework in Zambia and recommends actionable strategies for government and stakeholders to improve sector resilience.
CONCLUSION: Summarizes the key findings, emphasizing the urgent need for government intervention to safeguard aquatic ecosystems and secure food sources.

Frequently Asked Questions
What is the primary focus of this research paper?
The paper focuses on identifying and analyzing the specific problems caused by climate change on fisheries and aquaculture ecosystems within Zambia.
What are the central themes covered in the assignment?
The central themes include the physical and biological impacts of climate change, the current status of the Zambian fishing industry, and the evaluation of adaptation and mitigation strategies.
What is the main objective of the study?
The objective is to investigate climate change scenarios, analyze the resulting problems in the fisheries sector, and identify potential adaptation strategies for Zambia.
Which methodology was employed for this research?
The author utilized a literature review methodology, examining existing research papers, reports, and works from international organizations regarding climate change.
What topics are discussed in the main section of the paper?
The main section covers the environmental impacts on aquatic ecosystems, the specific effects of rising temperatures, changes in primary production, and challenges for aquaculture management.
Which keywords best characterize this document?
Key terms include wild capture fisheries, aquaculture, climate change, adaptation, mitigation, and sustainable management of aquatic resources.
How does the increase in average temperature specifically affect fish populations?
Higher temperatures alter metabolic rates, slow down growth, reduce maximum species size, and force species to migrate to cooler waters, often leading to reduced recruitment.
What role does the Zambian government play in climate change awareness?
The government acts through various units like the Climate Change Facilitation Unit (CCFU) and collaborates with civil society networks to address climate-related policy and adaptation.
