  • Desertification and Agriculture
    BRIEFING Desertification and agriculture SUMMARY Desertification is a land degradation process that occurs in drylands. It affects the land's capacity to supply ecosystem services, such as producing food or hosting biodiversity, to mention the most well-known ones. Its drivers are related to both human activity and the climate, and depend on the specific context. More than 1 billion people in some 100 countries face some level of risk related to the effects of desertification. Climate change can further increase the risk of desertification for those regions of the world that may change into drylands for climatic reasons. Desertification is reversible, but that requires proper indicators to send out alerts about the potential risk of desertification while there is still time and scope for remedial action. However, issues related to the availability and comparability of data across various regions of the world pose big challenges when it comes to measuring and monitoring desertification processes. The United Nations Convention to Combat Desertification and the UN sustainable development goals provide a global framework for assessing desertification. The 2018 World Atlas of Desertification introduced the concept of 'convergence of evidence' to identify areas where multiple pressures cause land change processes relevant to land degradation, of which desertification is a striking example. Desertification involves many environmental and socio-economic aspects. It has many causes and triggers many consequences. A major cause is unsustainable agriculture, a major consequence is the threat to food production. To fully comprehend this two-way relationship requires to understand how agriculture affects land quality, what risks land degradation poses for agricultural production and to what extent a change in agricultural practices can reverse the trend.

  • Assessing Climate Change's Contribution to Global Catastrophic
    Assessing Climate Change’s Contribution to Global Catastrophic Risk Simon Beard,1,2 Lauren Holt,1 Shahar Avin,1 Asaf Tzachor,1 Luke Kemp,1,3 Seán Ó hÉigeartaigh,1,4 Phil Torres, and Haydn Belfield1 5 A growing number of people and organizations have claimed climate change is an imminent threat to human civilization and survival but there is currently no way to verify such claims. This paper considers what is already known about this risk and describes new ways of assessing it. First, it reviews existing assessments of climate change’s contribution to global catastrophic risk and their limitations. It then introduces new conceptual and evaluative tools, being developed by scholars of global catastrophic risk that could help to overcome these limitations. These connect global catastrophic risk to planetary boundary concepts, classify its key features, and place global catastrophes in a broader policy context. While not yet constituting a comprehensive risk assessment; applying these tools can yield new insights and suggest plausible models of how climate change could cause a global catastrophe. Climate Change; Global Catastrophic Risk; Planetary Boundaries; Food Security; Conflict “Understanding the long-term consequences of nuclear war is not a problem amenable to experimental verification – at least not more than once" Carl Sagan (1983) With these words, Carl Sagan opened one of the most influential papers ever written on the possibility of a global catastrophe. “Nuclear war and climatic catastrophe: Some policy implications” set out a clear and credible mechanism by which nuclear war might lead to human extinction or global civilization collapse by triggering a nuclear winter.

What began as a struggle for survival became a predominance among living things, then, in wealthier societies, a relentless drive for comfort and pleasure. Even, perhaps especially, in less-developed countries (LDCs), where for many survival remains a struggle, the conquest of nature proceeds apace. "Development" is now a worldwide synonym for progress.' It is therefore ironic that the scope and effects of human activity actually threaten our survival as a species. Scientists and politicians cannot agree on the precise causes and implications of, let alone solutions to, such internation- al catastrophes as ozone layer depletion, global warming and species extinction.

  • Drought and Desertification in Iran
    hydrology Article Drought and Desertification in Iran Iraj Emadodin *, Thorsten Reinsch and Friedhelm Taube Institute for Crop Science and Plant Breeding, Group of Grass and Forage Science/Organic Agriculture, Hermann-Rodewald-Straße 9, 24118 Kiel, Germany * Correspondence: [email protected]; Tel.: +49-431-880-1516 Received: 1 April 2019; Accepted: 5 August 2019; Published: 7 August 2019 Abstract: Iran has different climatic and geographical zones (mountainous and desert areas), mostly arid and semi-arid, which are suffering from land degradation. Desertification as a land degradation process in Iran is created by natural and anthropogenic driving forces. Meteorological drought is a major natural driving force of desertification and occurs due to the extended periods of low precipitation. Scarcity of water, as well as the excessive use of water resources, mainly for agriculture, creates negative water balances and changes in plant cover, and accelerates desertification. Despite various political measures having been taken in the past, desertification is still a serious environmental problem in many regions in Iran. In this study, drought and aridity indices derived from long-term temperature and precipitation data were used in order to show long-term drought occurrence in different climatic zones in Iran. The results indicated the occurrence of severe and extremely severe meteorological droughts in recent decades in the areas studied. Moreover, the De Martonne Aridity Index (IDM) and precipitation variability index (PVI) showed an ongoing negative trend on the basis of long-term data and the conducted regression analysis. Rapid population growth, soil salinization, and poor water resource management are also considered as the main anthropogenic drivers.

  • Desertification: the Broader Context
    INVITED LECTURED Desertification: the broader context M.J. Kirkby University of Leeds (United Kingdom) ABSTRACT After over twenty years of research, there is still not complete consensus on even how to define desertification. This is reflected in the changing emphasis of UNCCD and EU programmes. The focus on physical processes in the 1990s has changed, first to an emphasis on the impacts of desertification and global change, and more recently towards sustainability rather than degradation as the core of most research effort, although much is still concerned with scenarios of possible future change. Different research tools are able to survey different windows on changing degradation status. Remote sensing methods, for example, provide an excellent window on the recent past, but little forecasting potential beyond projecting linear trends. Dynamic models add some understanding of the interaction of different components, and are increasingly engaging with socio-economic as well as strictly bio-physical processes, but are still limited by the intervention of the unexpected – the boom in biofuel demand, the credit crunch etc – that severely limit their forecasting horizons. This survey examines some of the over-arching relationships that must always constrain the relationships between population, food, land, water and energy, constraining the overall sustainability of global systems in a way that can only temporarily be ignored through irreversible mining of resources and exploitation of one region at the expense of another. The land sets constraints on food production that can partially be overcome through technological development, linked as both cause and effect to population growth, and may also be reduced by degradation.
