Harnessing the power of machine and deep learning for transferring joint species distribution models considering the structure of biotic interactions

open access: yesEcography, EarlyView.
The transferability of single or joint species distribution models ((j)SDMs) depends on their ability to predict beyond the observed environmental range and to remain consistent despite shifts in biotic interactions. Transfer accuracy may be improved by recent advances in the application of deep learning that provide greater flexibility and potentially

Wildfires Vegetation Recovery through Satellite Remote Sensing and Functional Data Analysis

open access: yesMathematics, 2021
In recent years, wildfires have caused havoc across the world, which are especially aggravated in certain regions due to climate change. Remote sensing has become a powerful tool for monitoring fires, as well as for measuring their effects on vegetation ...

Impacts of Social Assistance During the COVID‐19 Pandemic in Poor Remote Communities

open access: yesJournal of International Development, EarlyView.
ABSTRACT Providing social assistance to poor populations in remote communities in times of crises, such as pandemics, is challenging but crucial. This paper examines how food assistance during the COVID‐19 pandemic affected people's behaviour, using our surveys among over 400 rural communities without road access in the Peruvian Amazon. Food assistance

Diurnal Air–Surface Temperature Dynamics in Hong Kong: An Analysis Across Land Use and Climate Zones

open access: yesInternational Journal of Climatology, EarlyView.
Daytime and nighttime air temperature (Ta) from automatic weather stations and land surface temperature (Ts) derived from ASTER and Landsat 8–9 are used to examine the relationship between Ta and Ts. The spatial and statistical characteristics of Ta − Ts dynamics are further analysed across land use (LU) and local climate zones (LCZ).

Landsat-MODIS image fusion and object-based image analysis for observing flood inundation in a heterogeneous vegetated scene

open access: yesGIScience & Remote Sensing, 2019
Typhoon flooding normally occurs suddenly with short duration, and the thick cloud cover limits the ability of one single satellite to timely capture the inundation extent.

Object-Based Greenhouse Mapping Using Very High Resolution Satellite Data and Landsat 8 Time Series [PDF]

open access: yes, 2016
Greenhouse mapping through remote sensing has received extensive attention over the last decades. In this article, the innovative goal relies on mapping greenhouses through the combined use of very high resolution satellite data (WorldView-2) and Landsat

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, EarlyView.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Estimation of Fuel Water Content in the Forest Ecotone of Guangzhou Based on the PROSAIL Model

open access: yesRedai dili, 2023
Fuel moisture content (FMC), which is the ratio of equivalent water thickness (EWT) to dry matter content (DMC), plays a crucial role in the estimation of vegetation ignition probability and the fire propagation rate.
