Crop production in Harsh Environments covers all issues related to abiotic stresses,  some of them are listed below:

•  Introducing new and forgotten plants adopted with environmental stresses (ES)
•  Plant breeding and introducing new cultivars for crop production in areas affected by ES
•  Plant domestication for ES
• Plant nutrition under abiotic stresses
• Biotechnology and genetic engineering for increasing plant tolerance to ES
•  Seed science and technology for better crops establishment under ES
•  Application of microorganism (such as mycorrhizal fungi) for reducing negative impacts of ES on plant growth
•  Effect of climate change on the severity of ES
• Physiological responses of plants to ES

Some more detailed topics related to each of the abiotic stresses are presented below

•  Water stress: 
• Drought stress:
• Deficit irrigation
• Natural and chemical super absorbents
• Reuse of waste waters
• Transplantation for reducing consumed water
• Rainfed cultivation in arid and semi-arid areas
• Planting pattern design for dry regions
• Use of indigenous knowledge in the sustainable exploitation of water resources
• Flooding
•  Salinity stress:
• Halophytes domestication and cultivation
• Mitigation of the effects of salinity stress on plants germination and growth
• Ecophysiological response of plants to salinity stress
• Consumption of saline water for crop production
• Thermal stress:
• Heat stress
• Cold stress
• Freezing 
• Heavy metal stress
• Molecular mechanisms of resistance to heavy metals in plants
• Technical methods to improve plant resistance to heavy metal stress
• Phytoremediation to reduce the accumulation of heavy metals in the soil
• Mechanical stress
