Background
- Haihe Basin faces food security challenges due to water scarcity and degradation.
- Dense population and agricultural demands strain water resources.
- Existing practices struggle with water quality and quantity constraints.
Purpose Of The Study
- To develop a comprehensive spatial optimization (CSO) strategy for sustainable agriculture in the Haihe Basin.
- To balance food security needs with water availability and quality.
- To integrate crop management, land use, and breeding technologies.
Main Methods
- Developed a spatial planning model using linear programming.
- Incorporated water quantity and quality constraints.
- Integrated crop and soil management, land consolidation, and breeding technologies.
Main Results
- CSO strategy can increase total crop yield by 81% while reducing cultivated land by 3.0%.
- Potential to reduce sown area by 28% (820 Kha) if food demand is met.
- Reduced total nitrogen (N) losses by 23%-43% (139-252 Kt).
Conclusions
- The CSO strategy offers a feasible framework for enhancing crop yields in the Haihe Basin.
- The strategy effectively safeguards water quality and quantity.
- Sustainable food production is achievable by integrating advanced agricultural practices.

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
Under normal conditions, water taken up by the plant evaporates from leaves and other parts in a process called transpiration. In times of drought stress, water that evaporates by transpiration far exceeds the water absorbed from the soil, causing plants to wilt. The general plant response to drought stress is the synthesis of hormone...
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
Plant cell cytoplasm has a high solute concentration, which causes water to flow from the soil into the plant due to osmosis. However, excess salt in the surrounding soil increases the soil solute concentration, reducing the plant’s ability to take up...
The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that transport xylem sap are dead upon maturity, and the movement of xylem sap is a passive process.
Tracheids and vessel elements transport xylem sap
Tracheary elements are the transport cells of the xylem. They lack cytoplasm and organelles when they are mature and are considered part of the apoplast of the plant because they connect directly with the...
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
As humans' understanding of genetics advanced, improved crop varieties could be achieved more quickly. Artificial selection could be more directed, and crop varieties enhanced for favorable traits more quickly to produce better, more robust, or more palatable...
