Planetary boundaries related to land systems: recent research on global human appropriation of net primary production

Thurs, Nov 7th, 2013, 17 ct, Tieranatomisches Theater

 

Productive land area is a finite resource. But what does that mean in terms of possible limits to food, feed, fibre and bioenergy volumes that might be required globally in the future?

The original planetary boundary concept by J. Rockström and colleagues proposed a land-related boundary for cropland areas. Since, several commentaries have questioned the approach and argued in favour of analyzing land-related boundaries based on the earth's primary productivity (NPP) and current use. The human appropriation of net primary production (HANPP) is an indicator for the fraction of the productive capacities of global ecosystems used by humans through two processes: (i) land-use induced changes in NPP and (ii) harvest. Globally, HANPP doubled in the 20th century. Comparing HANPP maps with maps of current land use or cover allows estimates of the percentage of NPP of each land class currently appropriated by humans. The lecture presents recent empirical advances and discusses what we may learn about global planetary boundaries related to land, but also related to boundaries such as for nitrogen, phosphorous or water.

 

Helmut Haberl is Director of the Institute of Social Ecology Vienna, Alpen-Adria Universität, Austria.

His research focuses on human appropriation of net primary production (HANPP), ecological footprinting, societal energy metabolism and its relation to sustainable development. He is IPCC lead author for chapter 11 of the 5th assessment report (Working Group III ‘Mitigation’) and former member of the GLP Scientific Steering Committee and of the Scientific Committee of the European Environment Agency.

Landscape sustainability science: from vision to practice

Thurs, Dec 12th, 2013, 17 ct, Tieranatomisches Theater

 

Numerous scholars have called for place-based research to play a prominent role in sustainability science. Most recently, Jianguo Wu defined landscape sustainability science as “a place-based, use-inspired science of understanding and improving the dynamic relationship between ecosystem services and human well-being” (Landsc Ecol 28, 999-1023).

This lecture discusses recent advances in place-based social-ecological research, including a blurring of boundaries between the natural and social sciences, and growing conceptual and methodological pluralism, especially among “next generation” sustainability scientists. Drawing on a case study in Central Romania, a general, spatially explicit approach is presented that involves assessments of (i) social conditions and natural capital bundles, (ii) socialecological system dynamics, and (iii) current development trends.

The resulting understanding, in turn, can be used in combination with scenario planning to map how current development trends may be amplified or dampened in the future. The lecture concludes by highlighting key priorities for the future development of landscape sustainability science.

 

Jörn Fischer is Professor at the Faculty of Sustainability, Leuphana Universität Lüneburg, Germany.

His interdisciplinary activities are solution-oriented and combine landscape ecology, research on ecosystems and biodiversity, as well as ecosystem services. In 2010, he received a Sofja Kovalevskaja Award by the

Alexander von Humboldt Foundation and currently leads a transdisciplinary research project to support sustainable development in Transylvania, Romania.

Land change science challenges: causal relations, telecouplings and land grab

Thurs, Jan 16th, 2014, 17 ct, Tieranatomisches Theater

 

Land change science is now widely recognized as a fundamental component of global environmental change and sustainability research. This interdisciplinary field helps to understand the dynamics of land cover and

land use as a coupled human-environment system and thereby contributes to addressing environmental and societal problems. While huge advancements have been made in recent decades in, e.g., the capacity to monitor, model and map land changes, many research challenges for land change science remain still unresolved.

The lecture will discuss some of these emerging, conceptual issues, supported with empirical examples:

  • a) Land changes are the result of complex processes: How can we analyze important causal relationships in human-environment systems?
  • b) Nearly all land systems are affected by connectivity between distant places, or telecouplings: How does this challenge land change science’s epistemological perspectives, methodology and analytical approaches?
  • c) Emerging scarcity of land has fueled a waves of large global land acquisitions: How can such reallocation of land driven by distant actors influence local land systems in cascading ways beyond the direct occupation of land?

 

Anette Reenberg is Professor at the Department of Geosciences and Natural Resource Management, Københavns Universitet, Denmark. Her research addresses issues related to land change science and natural resource management strategies in rural landscapes, including adaptation to climate change. Focus is on humanenvironmental interaction explored in an interdisciplinary perspective. She acted as Chair and Office Leader for the GLP IPO and GLP Scientific Steering Committee from 2006 to January 2012.
