The study analyzed the daily extreme rainfall indices and its consequences on Meher (summer) season cereal crop calendar in the agro-climatic zones (ACZs) of a watershed. Long-term (1981-2019) rainfall data for 50 sample grid points with a spatial resolution of 5 5 km from Climate Hazards Group Infrared Precipitation (CHIRPS) was considered. Focus group discussions were employed to identifying [...]

In the following pages, we give a short introduction to a new integrated global assessment model: The Earth4All model of human wellbeing on a finite planet towards the year 2100. The Earth4All (E4A) model has evolved over a fifteen-year period and represents a summary of insights we have gained during all these years (See Appendix 1 for a list of the main publications that form the foundation for [...]

Majapahit was the largest Hindu-Buddhist empire that ruled the Indonesian archipelago from the late 13th to mid-16th centuries CE. Until recently, there is still a lot of history surrounding the Majapahit era that has yet to be revealed. One is about how environmental factors influenced the political dynamics at that time. This study tries to discuss the influence of hydroclimate regimes using [...]

Real-world environmental problems are typically vast, urgent, and complex. Confronted with such problems, we are often tempted to act fast by pulling together little bits and pieces from different fields and simply adding these to pre-existing models and frameworks. Seldom, though, do we pause long enough to look whether and for how long those larger structures we build can support reliable [...]

To accurately evaluate the spatiotemporal variability of ecosystem functions and services, as well as biodiversity, under a rapidly changing climate and shifting anthropogenic activities, it is an important but challenging task to retrieve information about past relationships among society, people’s lives, and the landscape. We watched documentary TV programs broadcast by the Japanese public [...]

Seagrass beds offer unique and vital ecological services as an important blue carbon ecosystem in coastal wetlands. Zostera japonica is an intertidal seagrass species native to eastern Asia and is one of the most widely distributed seagrass species in China. However, little is known on the long-term variations of Z. japonica extents. Automatic mapping method for Z. japonica seagrass beds is in [...]

Biomass carbon stocks (BCS) play a vital role in the climate system, but benchmarked estimates prior to the late 20th century remain scarce. Here, by making use of an early global forest resource assessment and harmonizing information on land use and carbon densities, we establish a global BCS account for the year 1950. Our best-guess BCS estimate is 450.7 PgC (median of all modulations: 518.3 [...]

Rural-urban classifications are essential for analyzing geographic, demographic, environmental, and social processes across the rural-urban continuum. Most existing classifications are, however, only available at relatively aggregated spatial scales, such as at the county scale in the United States. The absence of rurality or urbanness measures at high spatial resolution poses significant [...]

CORINE Land Cover is one of the most relevant Land Use Cover (LUC) databases in Europe because of its degree of detail and long time series. Although some studies have assessed the uncertainty of the database for specific years and periods, no work has been found that analyses all the available CORINE time series (1990-2018). In this study, we analyze the uncertainties of the CORINE time series [...]

Research on the uncertainty of Land Use Cover Change (LUCC) models is still limited. Through this paper, we aim to globally characterize the structural uncertainty of four common software packages (CA_Markov, Dinamica EGO, Land Change Modeler, Metronamica) and analyse the options that they offer for uncertainty management. The models have been compared qualitatively, based on their structures [...]

This chapter presents a Land Use Cover Change (LUCC) model application developed for Greater Sydney. It aims to help decision making in the context of the strategic and spatial planning of Greater Sydney. To this end, the model simulates the dynamics of industrial, low density residential and medium-high density residential areas at spatial resolution of 100x100 m. A series of three Land Use [...]

Field-based teaching forms an important part of BSc/BA degree courses in Human Geography, Physical Geography, Environmental Science and taught postgraduate courses. The aim of this policy is to ensure that all students and teaching staff are able, and feel safe, to participate fully in compulsory and optional field classes offered by the Department of Geography. This is shared with the intention [...]

A robust multi-functional framework for widespread planning of nature-based solutions (NBS) must incorporate components of social equity and hydro-environmental performance in a cost-effective manner. NBS systems address stormwater mitigation by increasing on-site infiltration and evaporation through enhanced greenspace while also improving various components of societal well-being, such as [...]

Tidal marshes are not only lost to human disturbance but also face the threat of sea level rise (SLR). However, current earth system models used to estimate future changes in wetland extent omit wetland’s real responses to SLR without field observations. We synthesised global data on sediment accretion rate (SAR) and surface elevation change (SEC) for tidal marshes and developed a mathematical [...]
