Characteristic | Significance | Possible Consequences | |
---|---|---|---|
Strengths | Irrigation systems | Ability to compensate for and cope with dry periods | Higher yield than rainfed agriculture |
Water usage regulation | Controlled and managed use of water resources | Conservation of water resources while covering users’ needs | |
Infrastructure and government bodies | Government and water management bodies already exist | Efficient and fast implementation of measures | |
Challenges | Irrigation systems | More water extraction More energy consumption | Increased pressure on water balance Increase in costs and reduction of profit |
Water usage regulation does not consider climate projections | Inability to cope with drought events Incremental water extraction as temperatures rise Increased extraction during drought events | Economic loss in at least one sector Cumulative pressure on water balance Drastic pressure on water balance | |
Crop rotation | High water demand Not ideal for humification | Possible ever-increasing water demand under climate change | |
Multiple water users | Allocating water for all users during drought events More water extraction | Water conflicts Increased pressure on water balance |
