Agricutural demand, production and land cover in IPCC climate scenarios

Shared Socioeconomic Pathways: Agricultural Demand, Production, and Land Cover

The Shared Socioeconomic Pathways (SSPs) are structured scenarios designed to explore possible futures for humanity, the environment, and critical sectors like agriculture and land use. Developed as part of the United Nations climate reports from the Intergovernmental Panel on Climate Change (IPCC), SSPs provide a valuable framework for understanding how societal and economic choices may influence agricultural demand, land use, and food security in the face of climate change.

Agricultural Challenges and Opportunities in SSPs. Greenhouse gas emissions and climate change significantly affect global agriculture, food production, and land cover. Rising temperatures, altered precipitation patterns, and extreme weather events are reshaping the suitability of land for crop cultivation and livestock farming. SSPs offer a way to examine how agricultural systems might evolve in various socioeconomic and climate conditions.

The scenarios incorporate factors like global population growth, economic development, and technological advances, which directly influence agricultural demand and production. Decisions about land management and food systems also shape land cover, driving deforestation, desertification, or conservation efforts. Understanding these dynamics is essential to meet the growing demand for food while minimising environmental impacts.

Key Features of SSPs in Agricultural Contexts. The SSP framework enables the study of interactions between agricultural practices, societal trends, and environmental outcomes. Each pathway presents distinct trajectories for agricultural productivity, land use change, and food security:

  • Sustainable Practices: Some SSPs emphasize agricultural methods that integrate sustainable practices, minimize greenhouse gas emissions, and preserve biodiversity.
  • Unsustainable Expansion: Other pathways explore futures where land cover changes due to deforestation or urban expansion, driven by escalating agricultural demand.
  • Technological Innovations: Advancements in agricultural technology play a central role in some scenarios, improving crop yields, water efficiency, and resilience to climate change.

Summaries of the Five Shared Socioeconomic Pathways (SSPs): Agricultural Implications

  • SSP1: The Sustainable Development Pathway This scenario envisions strong global cooperation, sustainable agriculture, and effective land management. Agricultural practices focus on efficiency, food security, and reduced environmental degradation, creating a balanced relationship between agricultural demand and land cover preservation
  • SSP2: The Middle-of-the-Road Pathway SSP2 reflects moderate economic growth and uneven progress. Agricultural production adapts gradually, but land degradation persists in certain regions due to inconsistent policies. Food systems remain vulnerable to climate impacts.
  • SSP3: The Regional Rivalry Pathway Fragmentation and a focus on regional self-reliance characterize this scenario. Limited agricultural trade and innovation hinder productivity, while land conversion for farming exacerbates deforestation and soil depletion.
  • SSP4: The Inequality Pathway Inequality within and between nations limits access to modern agricultural technologies, increasing food insecurity in marginalized regions. Wealthy nations maintain advanced farming systems, while vulnerable populations face degraded land cover and inefficient agricultural practices.
  • SSP5: The Fossil-fuelled Development Pathway This scenario emphasizes economic growth through resource-intensive practices. Agricultural expansion leads to widespread land conversion, high emissions, and reduced biodiversity, prioritizing short-term productivity over long-term sustainability.

Aligning Agriculture with Climate Targets. Each SSP includes variations aligned with climate goals, such as limiting global warming. For instance, achieving low radiative forcing (e.g., SSP1 – 2.6) requires sustainable agricultural practices, efficient land use, and innovative technologies like carbon capture. Conversely, transitioning high-emission pathways (e.g., SSP5 – 2.6) to climate-friendly agriculture demands unprecedented changes, including reforestation and carbon pricing in food systems.

The SSPs provide a structured approach to evaluate the interconnectedness of agricultural demand, production, and land cover under varying socioeconomic conditions. They highlight the challenges and opportunities for balancing food security and environmental sustainability, offering valuable insights for researchers, policymakers, and stakeholders in shaping resilient agricultural systems.
