Traditional and Local Ecological Knowledge for Land Use Mapping

Land use changes are a key driver in global environmental changes and had a significant impact on the climate at all scales. Various human activities that took place thousands of years ago have an impact on the earth's surface. Today, with the limited supply and high demand, land use crisis became a big issue for the most countries. Changes in land use are not actually only providing a history of the area, but it also describes the way of life of its local communities. In the interdisciplinary research for land use study, cultural values, knowledge and perceptions of knowledge has been recognized as a major factor in determining the adopted approach applied in land use management in that area. Therefore, this paper tries to evaluate the role and potential of the integration of TLEK and GIS in mapping the series of changes in land use.Keyword: Local knowledge, TLEK, land use mapping & conceptual framework

Global Environmental Changes

Rapid climate and land-use changes have been considered as the foremost threat to global biodiversity. China contains more than 3500 threatened higher plants, whereas the relative influence of climate and land-use changes on these endangered plants have not been explored simultaneously under topographical constraints. Here, using Taxus plants as the case study genus, we simulated the distribution range of threatened species under three scenarios of current and future climate and land-use conditions under topographical constraints. We also measured the associated difference in the responses of Taxus species to climate and land-use changes. Our results demonstrated the substantial influence of climate and land-use changes on the distributions of Taxus species. However, we observed different responses of Taxus species to these environmental changes. The distribution range of T. cuspidate Siebold & Zuccarini and T. mairei Lemee & H. Léveillé would substantially shrink, whereas the habitat range of T. fuana Nan Li & R. R. Mill would sharply expand under RCP 8.5(Representative Concentration Pathway scenarios) scenario. Meanwhile, T. wallichiana Zuccarini and T. chinensis (Pilger) Florin would experience apparent range shifts. Furthermore, topographical factors played non-negligible roles in shaping species distributions, and modifying the influence of climate and land-use changes. Together, these results provide robust evidence that even threatened species will have multiple responses to climate and land-use changes (e.g., shrinking, expanding, shifting). Our findings highlight that taking species ecological traits, habitat characteristics, and topographical constraints into account might provide valuable insights into threatened species conservation in the face of global environmental changes.

Abstract Global Global environmental changes, such as climate change, result from the interaction of human and natural systems. Understanding these changes and options for addressing them requires research in the physical, environmental, and social sciences, as well as engineering and other applied fields. In this essay, the authors provide their personal perspective on the role of the Aspen Global Change Institute (AGCI) in global change science over the past 25 years—in particular, how it has contributed to the integration of the natural and social sciences needed to research the drivers of change, the Earth system response, natural and human system impacts, and options for risk management. Drawing on inputs from other AGCI participants, we illustrate how, in our view, the history of AGCI is intertwined with the evolution of global change science as it has become an increasingly interdisciplinary endeavor.

Global Environmental Changes

Land-use and cover change (LUCC) impacts global environmental changes. Therefore, it is crucial to obtain cross-national level LUCC data that represents past and actual LUCC. As urban areas exhibit the most significant dynamics of the changes, accompanied by such processes as urban sprawl, it seems desirable to take into account LUCC information from such areas to acquire national level information. The paper analyses land-use changes (LUCs) in urban areas in Czechia, Poland, and Slovakia. The analysis is based on functional urban area (FUA) data from the European Urban Atlas project for 2006 and 2012. The area of urbanised land grew at the expense of agricultural areas, semi-natural areas, and wetlands over the investigated period in all three countries. The authors determined LUC direction models in urban areas based on the identified land-use change. The proposed LUC direction models for the investigated period and area should offer national level LUC data for such purposes as modelling of future changes or can be the point of reference for planning analyses. The paper proposes the following models: mean model, median model, weighted mean model where the weight is the urbanised to vegetated area ratio, and weighted mean model where the weight is the share of urbanised areas. According to the proposed LUC models, areas considered as urbanised grow in FUAs on average in six years by 5.5900‰ in Czechia, 7.5936‰ in Poland, and 4.0769‰ in Slovakia. Additionally, the change models facilitated determination of a LUC dynamics ratio in each country. It reached the highest values in Poland and the lowest in Slovakia.

Global Environmental Changes

Crustaceans present a remarkable variety of forms that differ greatly in body size and growth strategies (determinate or indeterminate). This diversity reflects the long evolutionary history of this group and the variety of environments a crustacean may inhabit. It is rooted in a wide array of internal (physiological, structural) growth constraints and different extrinsic ecological factors determining the extent to which the body size of an individual crustacean attains its upper limit. We briefly review the combined effects of these factors with a focus on the effects of food quality and quantity, predation, and temperature on life histories in the context of an individual, as well as at the population and community levels. We discuss the discrepancy between the possible and the attained body size in an attempt to resolve the extent to which the observed pattern (1) is genetically based, (2) reflects the adaptive plasticity of the phenotype, and (3) is driven by global environmental changes.

Diversity Dynamics

The Eocene–Oligocene transition (EOT) represents a period of global environmental changes particularly marked in Europe and coincides with a dramatic biotic turnover. Here, using an exceptional fossil preservation, we document and analyse the diversity dynamics of a mammal clade, Cainotherioidea (Artiodactyla), that survived the EOT and radiated rapidly immediately after. We infer their diversification history from Quercy Konzentrat–Lagerstätte (south-west France) at the species level using Bayesian birth–death models. We show that cainotherioid diversity fluctuated through time, with extinction events at the EOT and in the late Oligocene, and a major speciation burst in the early Oligocene. The latter is in line with our finding that cainotherioids had a high morphological adaptability following environmental changes throughout the EOT, which probably played a key role in the survival and evolutionary success of this clade in the aftermath. Speciation is positively associated with temperature and continental fragmentation in a time-continuous way, while extinction seems to synchronize with environmental change in a punctuated way. Within-clade interactions negatively affected the cainotherioid diversification, while inter-clade competition might explain their final decline during the late Oligocene. Our results provide a detailed dynamic picture of the evolutionary history of a mammal clade in a context of global change.
