Rice is the single most important crop for food security in Asia. Knowledge about the distribution of rice fields is also relevant in the context of greenhouse-relevant methane emissions, disease transmission, and water resource management. Copernicus Sentinel-1 provides the first openly available archive of C-band SAR (synthetic aperture radar) da...

Rice is the most important food crop in Asia and rice exports can significantly contribute to a country's GDP. Vietnam is the third largest exporter and fifth largest producer of rice, the majority of which is grown in the Mekong Delta. The cultivation of rice plants is important, not only in the context of food security, but also contributes to gr...

Rice is an important food crop and a large producer of green-house relevant methane. Accurate and timely maps of paddy fields are most important in the context of food security and greenhouse gas emission modelling. During their life-cycle, rice plants undergo a phenological development that influences their interaction with waves in the visible li...

Sentinelsat makes searching, downloading and retrieving the metadata of Copernicus Sentinel satellite images (http://www.esa.int/Our_Activities/Observing_the_Earth/Copernicus/Overview4) from the Copernicus Open Access Hub (https://scihub.copernicus.eu/) easy. The full documentation is published at http://sentinelsat.readthedocs.io/. Installation re...

Aquaculture, the farming of aquatic organisms, such as fish, shrimp and molluscs, is one of the fastest growing food production sectors, supplies more than half of the fish consumed today and is a primary source of animal protein and essential fatty acids for millions of people. With an average annual growth rate of 7.2 %, world aquaculture product...

Rice is the primary food crop for more than half of the world’s population and responsible for over 50% of the daily calorie intake for most Asian people. Asia’s biggest rice producers are facing increasing pressure to ensure food security due the consequences of population and economic growth. At the same time demand for rice imports is increasing...

Rice is Asia’s most important food crop and contributes significantly to the GDP through exports. Knowledge about its production is significant in the contexts of, not only food security, but also water management, trade policy, greenhouse gas emission and hydrological modelling. Paddy fields in Asia are often located in coastal lowlands and river...

Aquaculture is the fastest growing sector in the global food industry. Growing global population and changing consumer behavior lead to a sharp increase of worldwide production of aquatic products from 13 to 76 million tonnes during the past 25 years at an annual growth rate of 6.7 percent. Today every second fish comes from aquaculture, which beca...

Aquaculture makes a crucial contribution to global food security and protein intake and is a basis for many livelihoods. Every second fish consumed today is produced in aquaculture systems, mainly in land-based water ponds situated along the coastal areas. Satellite remote sensing enables high-resolution mapping of pond aquaculture, facilitating in...

The farming of aquatic organisms, such as fish, shrimp and mollusks has experienced considerable growth during the past 30 years. In this study, we present a method for the derivation of aquaculture ponds from high resolution SAR time series data and its potential for the approximation of aquaculture harvest volume. The Copernicus Sentinel-1 missio...

Aquaculture is one of the fastest-growing animal food production sectors worldwide, the main protein source in many countries and offers great potential for global food security. While capture fisheries production stagnated over the past years, aquaculture is already contributing nearly half of the total volume of aquatic foods in human consumption...

Rice is the most important food crop in Asia and the mapping and monitoring of paddy rice fields is an important task in the context of food security, food trade policy, water management and greenhouse gas emissions modelling. Asia’s biggest rice producers are facing increasing pressure in terms of food security due to population and economic growt...

We present an earth observation based approach to detect aquaculture ponds in coastal areas with dense time series of high spatial resolution Sentinel-1 SAR data. Aquaculture is one of the fastest-growing animal food production sectors worldwide, contributes more than half of the total volume of aquatic foods in human consumption, and offers a grea...

Rice is the most important food crop in Asia and the mapping and monitoring of paddy rice fields is an important task in the context of food security, food trade policy, water management and greenhouse gas emissions modelling. Asia’s biggest rice producers are facing increasing pressure in terms of food security due to population and economic growt...

Aquaculture is one of the fastest-growing animal food production sectors worldwide, became the main source of valuable animal protein in many countries and offers great potentials for global food security. While capture fisheries production stagnated over the past years, aquaculture has seen a remarkably increase from 6.2 Mio tones in 1983 to 70.2...

This poster presents first results from our rice mapping approach using time-series of MODIS and Sentinel-1. Time-series of MOD13Q1 and MYD13Q1 are used to generate medium resolution rice masks (250m). These masks are then used with a spatial buffer to reduce the amount of Sentinel-1 data to process. The remaining data from the Sentinel-1 time-seri...

Rice is the most important food crop in Asia and the mapping and monitoring of paddy rice fields is an important task in the context of food security, food trade policy and greenhouse gas emissions modelling. Two countries where rice is of special significance are China, the largest producer and importer of rice, and Vietnam, where rice exports con...

Aquaculture is one of the fastest-growing animal food production sectors worldwide and is the main source of valuable animal protein in many countries. The farming of fish, crustaceans and mollusks generated income and employment for many people in rural coastal areas and has attracted considerable attention for its high export value and potentials...

Aquaculture is one of the fastest-growing animal food production sectors worldwide and is the main source of animal protein in many countries. The farming of fish, crustaceans and mollusks has attracted considerable attention in coastal areas for its high export value and potentials in terms of protein supply and global food security. Nearly 90 per...

Aquaculture is the fastest-growing animal food production sector worldwide and is becoming the main source of aquatic animal food in human consumption. Depletion of wild fishery stocks, rising global populations, continuing demand for food fish, and international trade has driven aquaculture's tremendous expansion during the last decades - in terms...

Rice is the most important food crop in Asia, and the timely mapping and monitoring of paddy rice fields subsequently emerged as an important task in the context of food security and modelling of greenhouse gas emissions. Rice growth has a distinct influence on Synthetic Aperture Radar (SAR) backscatter images, and time-series analysis of C-band im...
