Sensitivity of vegetation indices and gross primary production of tallgrass prairie to severe drought
Drought affects vegetation photosynthesis and growth.Many studies have used the normalized difference vegetation
index (NDVI), which is calculated as the normalized ratio between near infrared and red spectral bands ...
Resilient and efficient agro-ecosystems under changing climate and demography
The presentation held in Dharwad (India) by dr. Biradar analyses the effects of changing climate on agriculture and proposes climate- smart practices. The stresses agriculture faces are multiple, some of which include ...

Potentials of Geoinformatics application in mapping NUS species for food and nutritional security
Geo- informatics presents great potential in the context of sustainable Agro-ecosystems development through mapping and monitoring. These include: crop types, corp associations, crop suitability, crop yield, cropping ...
Agricultural Intensification: Combating Food/Water Security Challenges Using Remote Sensing and GIS
This special issue aims to provide a knowledge base that is focused on geospatial mapping approaches for a better understanding of spatiotemporal dynamics of agricultural intensification from food/water security standpoints. ...
INTELLIGENT OBJECT BASED SMOOTHING: AN ALGORITHM FOR REMOVING NOISES IN THE CLASSIFIED SATELLITE IMAGE
The existing smoothing algorithms like mean, median, majority/mode filters are not efficient in smoothing the classified image derived from the satellite data. Mean filter alters original class pattern and also it is ...
Mapping deciduous rubber plantations through integration of PALSAR and multi-temporal Landsat imagery
Due to increasing global demand for natural rubber products, rubber (Hevea brasiliensis) plantation expansion
has occurred in many regions where it was originally considered unsuitable. However, accurate maps
of rubber ...
A 50-m Forest Cover Map in Southeast Asia from ALOS/ PALSAR and Its Application on Forest Fragmentation Assessment
Southeast Asia experienced higher rates of deforestation than other continents in the 1990s and still was a hotspot of forest
change in the 2000s. Biodiversity conservation planning and accurate estimation of forest carbon ...
Development of Decadal National Land Cover Database for Jordan
The main objective of this study is to introduce the first consistent long term land cover database for Jordan. The Jordan National Land Cover Database (JNLCD) consists of four land cover maps for the years 1984, 1991, ...
