This paper examines the impacts of climate change on irrigated agriculture in southern Pakistan. The Pakistani provinces of Sindh and Punjab are part of the Lower Indus Basin, where the Indus River is the main source of irrigation. Statements about the future development of wheat production are difficult because they are based on climate forecasts, which themselves exhibit a high degree of variance. Accordingly, relevant literature shows differences in statements about the influence of climate change on wheat production and usually focuses on the influence of temperature, precipitation and extreme weather, but does not consider the discharge of the Indus River.
This paper reviews current research findings from various sources based on the factors of (1) temperature and precipitation, (2) extreme weather events, and (3) Indus runoff volume, and is the first paper to combine all three factors to make predictions about wheat production. Finally, an overview of possible adaptation strategies is provided.

Objectives and Key Themes
This study aims to review existing research on climate change in the Lower Indus Basin (LIB) and its impacts on wheat production. Specifically, it focuses on the effects of temperature, precipitation, extreme weather events, and Indus River runoff on wheat yields. The main objective is to answer the question: What implications for wheat production in the LIB can be derived from climate change and its impacts on Indus River runoff?
- Climate change impacts on wheat production in the Lower Indus Basin
- Influence of temperature and precipitation changes on wheat yields
- Impact of extreme weather events on wheat cultivation
- Role of Indus River runoff in irrigation and its implications for wheat production
- Adaptation strategies for wheat production in a changing climate
Chapter Summaries
The first chapter introduces the research topic and highlights the significance of wheat production in Pakistan's food security. It discusses the challenges posed by climate change and existing research gaps, particularly the limited focus on the impact of Indus River runoff.
The second chapter describes the study area, focusing on the physiographic characteristics and agricultural practices of the Lower Indus Basin, particularly the provinces of Sindh and Punjab. It emphasizes the importance of wheat cultivation and its reliance on irrigation.
The third chapter presents a review of existing literature on climate change in the Indus Basin, focusing on temperature, precipitation, and Indus River runoff changes. It summarizes the potential impacts of these changes on the region's water resources.
The fourth chapter discusses the implications of climate change for wheat production in the LIB, examining the effects of temperature, extreme weather, and Indus River runoff on yields. It considers adaptation strategies to mitigate these impacts.
