Abstract:
... Accurate, long time-series, high-resolution mapping of built-up land dynamics is essential for understanding urbanization and its environmental impacts. Despite advances in remote sensing and classification algorithms, built-up land mapping which only uses spectral data and derived indices remains prone to uncertainty. We mapped the extent of built-up land in the North China Plain, one of China’s ...

Abstract:
... Land-use change alters the dynamics of freshwater ecosystem services flows by affecting both service supply (by influencing hydrological processes and runoff) and demand (via changes in human water use). However, few studies have considered the wide range of effects of land-use change on freshwater ecosystem services' flows. In this study, we distinguished the impacts of changing water supply and ...

Abstract:
... The United Nations 2030 Agenda brings a holistic and multi-sectoral view on sustainability via the Sustainable Development Goals (SDGs). However, a successful implementation of this agenda is contingent on understanding the multiple, complex interactions among SDGs, including both synergies and trade-offs, for informing planning for sustainability at the local level. Using a case study in the Goul ...
case studies; sustainability science and engineering; sustainable development; Australia
Abstract:
... The Sustainable Development Goals (SDGs) recognise the importance of action across all scales to achieve a sustainable future. To contribute to overall national- and global-scale SDG achievement, local communities need to focus on a locally-relevant subset of goals and understand potential future pathways for key drivers which influence local sustainability. We developed a participatory method to ...
arable soils; cropland; models; sustainable development; China; India
Abstract:
... To achieve responsible consumption and production under UN Sustainable Development Goal (SDG) 12, national agri-food consumption and production need to be assessed against environmental limits. We downscaled the land-system change planetary boundary and allocated national-scale cropland environmental limits for agri-food consumption via fair-share allocation based on population, and for agri-food ...

Abstract:
... Computational and data handling limitations have constrained time-series analyses of land-cover change at high-spatial resolution over large (e.g., continental) extents. However, a new set of cloud-computing services offer an opportunity for improving knowledge of land change at finer grain. We constructed a historical set of seven high-resolution wall-to-wall land-cover maps at continental scale ...

Abstract:
... Global food trade enables the flow of dietary nutrients between countries. However, little is known about whether trade improves nutrient supply of countries most in need. Using detailed production and bilateral trade data, we found that despite strongly connected global nutrient networks, trade did not substantively improve the nutrient adequacy of most low/lower-middle income countries (~40% of ...
... The dataset presents the raw data collected through household surveys of smallholder farmers on adaptation to climatic variabilities and change in Sudurpaschim Pradesh (Far Western Province), Nepal. The dataset comprises farmers' responses on the likely determinants of adaptation decisions, actual uptake of adaptation measures, and the barriers to adaptation. We collected the data by conducting fa ...
... Smallholder agriculture is a major contributor to global food production and is vital for ensuring food security in many developing countries. Smallholder agriculture is a typically complex and heterogeneous social-ecological system that is especially susceptible to climatic variability. Research has often focused on examining climate impacts on crops in smallholder agriculture. However, the resil ...

Abstract:
... While the need to reduce the impacts of pesticide use on the environment is increasingly acknowledged, the existing data on the use of agricultural chemicals are hardly adequate to support this goal. This study presents a novel, spatially explicit, national-scale baseline analysis of pesticide toxicity hazard (the potential for chemicals to do harm). The results show an uneven contribution of land ...
... Non-timber forest products (NTFPs) contribute to the well-being of mountain communities in many ways but their availability is being impacted by climate change. Policy and programs to enhance adaptation can alleviate these impacts, but to be effective they require an understanding of mountain community perceptions of climate change impacts on NTFPs and the perceived barriers to climate change adap ...
... Modeling is a crucial approach for understanding the past and exploring the future of coupled human-natural systems. However, uncertainty in various forms challenges inferences from modeling results. Model-based support for decision-making has increasingly adopted an emerging exploratory approach. This approach addresses uncertainty explicitly through systematically exploring the implications of m ...
... Addressing the triple burden of malnutrition requires significant improvements in nutritional outcomes from food production. We assessed the nutrient adequacy of primary production for 177 countries between 1995 and 2015 by comparing population requirements to dietary nutrient production based on highly disaggregate crop, livestock, and seafood data. While total production can adequately provide t ...

Abstract:
... To sustain water-dependent economic and socio-ecological systems, natural capital and its interactions with other types of capital is gaining attention, but a clear understanding of how to manage natural capital sustainably and how to make decisions relevant to water-related ecosystem services is yet to be achieved. In this study, we extended the framing of water-related ecosystem service flows by ...
algorithms; basins; hydrologic models; prediction; watersheds; Australia
Abstract:
... We present a two-step framework for calibrating complex, many-parameter hydrological models at basin-scale. The framework first calibrates parameters for each catchment/sub-basin sequentially and then fine-tunes parameters as needed. We implemented a comprehensive learning particle swarm optimiser (CLPSO) as the calibrator and applied the two-step CLPSO tool in calibrating parameters of a water ac ...

Abstract:
... This dataset presents data collected from household surveys from Upper Madi Watershed of Nepal describing the benefits of non-timber forest products (NTFPs) to people of mountain ecosystems, their perceptions of climate change, and perceived impacts of climate change on NTFPs ecosystem services. The data were collected from 278 households that were randomly selected from the four villages in the w ...

Abstract:
... The diversity of local conditions across regions has led to numerous challenges and opportunities for the implementation of global sustainability frameworks such as the Sustainable Development Goals. A grassroots transformative change led by local communities, cities, and businesses can offer a promising approach for achieving sustainability, tailored to the unique conditions of each context. Draw ...

Abstract:
... CONTEXT: The contribution of forest ecosystem services to human well-being varies over space following the dynamics in forest cover. Use of machine learning models is increasing in projecting forest cover changes and investigating the drivers, yet references are still lacking for selecting machine learning models for spatial projection of forest cover patterns. OBJECTIVES: We assessed the ability ...

Abstract:
... This study presents the first application of deep learning techniques in capturing long-term, time-continuous forest cover dynamics at a continental scale. We developed a spatially-explicit ensemble model for projecting Australia's forest cover change using Long Short-Term Memory (LSTM) deep learning neural networks applied to a multi-dimensional, high-resolution spatiotemporal dataset and run on ...
algorithms; case studies; entropy; models; uncertainty; Iran
Abstract:
... Despite recent advances in quantifying land-use/cover change (LUCC) transition potential, transition rules are often not transparent and uncertainty is rarely made explicit. Here, we introduce DoTRules—a dictionary of trusted rules—as a transparent alternative to calculate transition potential in cellular automata models. Rules relate LUCC variables to the observed historical changes. Shannon entr ...
