Using Montarice in central Adriatic Italy as a case study, this paper focuses on the extraction of the spectral (i.e., plant colour) and geometrical (i.e., plant height) components of a crop canopy from archived aerial photographs, treating both parameters as proxies for archaeological prospection. After the creation of orthophotographs and a canopy height model using image-based modelling, new...

Remote sensing has the potential to provide estimates of important inputs for the land process models, for instance the land cover type, the soil moisture and the LAI. Such models can provide information that is crucial for a number of applications such as flood and drought prediction, crop irrigation scheduling, and meteorology. Also, land cover maps provide fundamental information to many asp...

Mozambique, like many African countries, is already highly susceptible to climate variability and extreme weather events. Climate change threatens to heighten this vulnerability. In order to evaluate potential impacts and adaptation options for Mozambique, we develop an integrated modelling framework that translates atmospheric changes from general circulation model projections into biophysical...

The production of agricultural cultivates under intensive systems requires of big quantities of pesticides for fitosanitary control. Pesticides application is a major component of tomato production costs under greenhouse in Almería, Spain, and the excess in their applications have a great negative impact on the environment. A pesticide application is ideal if the spraying coverage is presented ...

At the European scale, nitrate concentration is the most important parameter that determines groundwater quality. Since in most cases nitrate input into the aquifer is a non-point source pollution problem, measures to reduce nitrate leaching have to be designed on the aquifer scale. In this context we have coupled the unsaturated, vertical soil water and nitrogen transport model SIMWASER/STOTRA...

BACKGROUND Reduction of child undernutrition is one of the Sustainable Development Goals for 2030. Achievement of this goal may be made more difficult in some settings by climate change through adverse impact on agricultural productivity. However, there is only limited quantitative evidence on the link between household crop harvests and child nutrition. We examined this link in a largely subsi...
