Climate change and other anthropogenic
disturbances can lead to the loss of genetic variation
and thereby affect evolutionary potential and survival
of plant populations in the wild. We examined these
predictions in the primary wild relative of...

The Kingdom of Saudi Arabia (KSA) is under
extreme water shortage conditions. About 80 % of water in
KSA is utilized by the agricultural sector; therefore, proper
management of irrigation water is required to produce more
food from less water. Water...

Maize (Zea mays L.) is the second most commonly grown crop worldwide and number one staple food in Africa where it accounts for more than 50% of the energy requirements. However, despite its widespread cultivation and the significance of maize...

tImproving crop area and/or crop yields in agricultural regions is one of the foremost scientific challengesfor the next decades. This is especially true in irrigated areas because sustainable intensification of irri-gated crop production is...

Accurate information on the gross primary production (GPP) of paddy rice cropland is critical for assessing and monitoring rice growing conditions. The eddy co-variance technique was used to measure net ecosystem ex- change (NEE) of CO2 between paddy...

Characterization of soil properties is a key step in understanding the source of spatial
variability in the productivity across agricultural fields. A study on a 16 ha field located in the
eastern region of Saudi Arabia was undertaken to investigate...

Due to rapid population growth and urbanization, paddy rice agriculture is experiencing substantial changes in the spatiotemporal pattern of planting areas in the two most populous countries—China and India—where food security is always the primary...

Dryland biodiversity has only recently got due attention because of its potential to contribute in overcoming the effects of global challenges caused by land degradation and and climate change (FAO, 1989). More particularly, the non-tropical dryland...

The Asian Migratory locust (Locusta migratoria migratoria L.) is a pest that continuously threatens crops
in the Amudarya River delta near the Aral Sea in Uzbekistan, Central Asia. Its development coincides with the growing period of its main food...

Area and spatial distribution information of paddy rice are important for understanding of food security, water use, greenhouse gas emission, and disease transmission. Due to climatic warming and increasing food demand, paddy rice has been expanding...

Dryland cereals and legumes are important crops in farming systems across the world. Yet they are frequently neglected among the priorities for international agricultural research and development, often due to lack of information on their magnitude...

Optimum wheat (Triticum aestivum L.) yield can be achieved by
developing and growing the best genotypes in the most suited
environments. However, exhaustive field measurements are
required to characterize plants with desirable traits in breeding
plot...

The vulnerability of wheat is likely to increase due to an increase of heat stress
according to recent wheat-production simulation models combined with local
climate-change data. This is particularly an issue affecting dryland areas where global
cli...

Extensive forest changes have occurred in monsoon Asia, substantially affecting climate, carbon cycle
and biodiversity. Accurate forest cover maps at fine spatial resolutions are required to qualify and
quantify these effects. In this study, an...

management of water resources, and estimation of greenhouse gas (methane) emissions. Paddy rice agriculture
has expanded rapidly in northeastern China in the last decade, but there are no updated maps of
paddy rice fields in the region. Existing...

A seamless vegetation type map of India (scale 1: 50,000) prepared using medium-resolution IRS LISS-IIIimages is presented. The map was created using an on-screen visual interpretation technique and has anaccuracy of 90%, as assessed using 15,565...
