Challenges and Strategies for Management of Problematic Soils and Waters

Problematic soils are a global concern due to the rising population and shrinking cultivable land, decreasing by 1-2% per year. This threatens the productivity of land needed for food security. Around 1125 million hectares are salt-affected, with 76 million hectares impacted by human activities like salinization, sodification, and acidification. The causes include high temperature, low rainfall, poor irrigation, and harmful agricultural practices like excessive tillage and fertilizer use. These degrade soil, making it non-productive. Advances in soil remediation, including biochar, water-saving irrigation, precision fertilization, and afforestation, offer solutions. Sustainable management strategies like reduced tillage and raised beds improve soil structure, water, and nutrient efficiency. Chemical and biological reclamation, including the use of salt-tolerant plants, can transform problematic soils into productive assets, enhancing food security and supporting farmers' incomes. Sustainable management is crucial for restoring soil health and agricultural productivity.
