Global food demand is growing rapidly. Livestock grazing can provide a valuable source of protein, but conventional grazing is often unsustainable. We studied an 800,000-ha section of a threatened ecoregion in southeastern Australia. Conventional management in the region involves continuous livestock grazing with few rest periods and regular fertilizer application. By using remotely sensed data on tree cover and extensive field data on livestock grazing regimes, soil chemistry, tree diameters, and tree regeneration, we show that the region is facing a tree regeneration crisis. Under conventional management, across the region, millions of hectares of land currently supporting tens of millions of trees will be treeless within decades from now. This would have severe negative ramifications for biodiversity and key ecosystem services, including water infiltration and shade provision for livestock. However, we identified an unexpected win-win solution for tree regeneration and commercial grazing. A relatively new practice in the region is fast-rotational grazing, characterized by prolonged rest periods in between short, intensive grazing events. The probability of regeneration under fast-rotational grazing was up to 4-fold higher than under conventional grazing, and it did not differ significantly from the probability of regeneration in ungrazed areas. In addition, trees were more likely to regenerate where soil nutrient levels were low. These findings suggest that the tree regeneration crisis can be reversed by applying low-input, fastrotational grazing. New policy settings supporting these practices could signal a turning point for the region, from ecological decline to ecological recovery.countryside biogeography ͉ grassy box woodlands ͉ holistic management ͉ rotational grazing ͉ scattered trees
1. The Special Feature led by Sutherland, Dicks, Everard, and Geneletti (Methods Ecology and Evolution, 9, 7-9, 2018) sought to highlight the importance of "qualitative methods" for conservation. The intention is welcome, and the collection makes many important contributions. Yet, the articles presented a limited perspective on the field, with a focus on objectivist and instrumental methods, omitting discussion of some broader philosophical and methodological considerations crucial to social science research. Consequently, the Special Feature risks narrowing the scope of social science research and, potentially, reducing its quality and usefulness. In this article, we seek to build on the strengths of the articles of the Special Feature by drawing in a discussion on social science research philosophy, methodology, and methods.2. We start with a brief discussion on the value of thinking about data as being qualitative (i.e., text, image, or numeric) or quantitative (i.e., numeric), not methods or research. Thinking about methods as qualitative can obscure many important aspects of research design by implying that "qualitative methods" somehow embody a particular set of assumptions or principles. Researchers can bring similar, or very different, sets of assumptions to their research design, irrespective of whether they collect qualitative or quantitative data.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
Adaptive capacity is increasingly recognized as essential for maintaining the resilience of social–ecological systems and for coping with environmental change. Four main requirements enable societies to successfully adapt to change: (1) the will and intention to maintain social–ecological resilience, (2) knowledge about current problems and the desired direction of change, (3) proactive behavior, and (4) the capacity to change existing patterns of behavior. The adaptive capacity of societies can be greatly enhanced by fostering the adaptive capacity of their individual members. Considerable knowledge about how to foster the adaptability of individuals exists in the science of education and in cognitive and social psychology. Developing the ability to learn flexibly in a variety of ways, contexts, and circumstances is an important element of developing adaptive capacity. The widespread implementation of modern teaching approaches in the education sector could make a substantial contribution to building and maintaining social–ecological resilience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
