Dates losses and Its Impact on Economic Resources in Saudi: Present and Prospect
This study utilizes time-series data from 1992 to 2023 to analyze the economic and spatial impacts of date production losses in Saudi Arabia, revealing a unidirectional causal link from harvested area to losses and projecting a future decline in losses that underscores the need for improved post-harvest management to support sustainable agricultural goals.

The Big Picture: The "Date Palm" Economy
Imagine Saudi Arabia's agriculture as a giant, bustling kitchen. In this kitchen, the Date Palm is the star chef. It's not just a fruit; it's a cultural icon and a massive economic engine, providing about 75% of the country's total fruit production.
However, even the best chefs make mistakes. Sometimes, ingredients spoil before they reach the customer, or they get dropped on the floor. In this study, the authors are looking at how much "fruit" is being wasted (dates losses) and asking a critical question: How much of our precious land and water are we wasting just because we aren't catching these dates in time?
The Investigation: Looking at the Past (1992–2023)
The researchers acted like detectives, gathering data from the last 30 years (1992 to 2023) from a global database called FAO. They wanted to see how three specific things were dancing together:
- Dates Lost: The weight of dates that went bad or were thrown away.
- Harvested Area: The size of the land used to grow the dates.
- Total Production: The total amount of dates picked.
They used advanced math tools (like a "time machine" for statistics) to see if these three variables were connected in the long run.
The Key Findings
1. The "One-Way Street" of Causality
The study found a specific direction to the relationship between these variables. Think of it like a one-way street:
- The Land Drives the Loss: The size of the harvested area (the land) pushes the amount of dates lost and the total production.
- The Reverse isn't True: The amount of dates lost does not push the land to grow bigger.
- Analogy: Imagine a factory floor (the land). If you make the factory floor bigger, you might produce more products, but you might also accidentally drop more products. However, dropping products doesn't magically make the factory floor expand. The land size is the "boss" here.
2. The "Leaky Bucket" Effect
The researchers calculated exactly how much land is wasted when dates are lost.
- The Math: For every 10 tons of dates that go to waste, it is equivalent to wasting 0.046 hectares of land.
- The Metaphor: Imagine you are filling a bucket with water (dates) to water a garden (land). If the bucket has a hole (losses), you have to keep pouring more water just to keep the garden alive. The study says that every time you lose a specific amount of dates, it's as if you are throwing away a small patch of garden that could have been used for something else.
- The Result: Reducing waste isn't just about saving fruit; it's about saving the land itself. If we stop the leak, we don't need to use as much land to get the same result.
3. The Future Forecast: A Slow Down
The researchers looked into a crystal ball to predict what will happen between now (2023) and 2035.
- The Trend: In the past (1992–2023), the amount of dates lost was growing at a rate of about 2.18% per year.
- The Prediction: For the future (2023–2035), that growth rate is predicted to drop to almost zero (0.0099%).
- The Meaning: The curve is flattening out. The study suggests that the amount of wasted dates is finally starting to decrease or stabilize.
- Why? The authors hint that this is likely due to the Saudi government's efforts to meet global goals (like the UN's goal to cut food waste in half by 2030). It's like a driver finally hitting the brakes after speeding for decades.
The Conclusion: What Should We Do?
The paper concludes that the best way to protect Saudi Arabia's economic resources (its land and water) is to stop the leak.
- The Fix: We need better harvesting techniques, better storage (like better fridges), and better trucks to move the dates without them getting crushed.
- The Payoff: By fixing the supply chain, we don't just save dates; we save the land. It's a win-win: less waste means we can grow more food on the same amount of earth, making the whole system more sustainable.
In short: The study proves that when we lose dates, we are also losing land. By fixing how we handle dates, we can stop wasting our most valuable resource: the ground beneath our feet.
