# Alqueva Olive Mega-Farms — Live Satellite Health Report

> Satellite monitoring of Alqueva's super-intensive olive plantations tracks canopy density and irrigation performance month by month — free.

## About this region

The Alqueva reservoir in Portugal's Alentejo is the hub of a new kind of agriculture: super-intensive olive farming. Drip-irrigated hedgerows of Arbequina and Arbosana olives, planted at densities of 1,500+ trees per hectare, are machine-harvested for olive oil at industrial scale. This is a modern, high-input system — the opposite of Jaén's traditional rain-fed groves — and the Alqueva irrigation project transformed this semi-arid region by guaranteeing water from Europe's largest artificial lake.

## Climate & growing cycle

Flowering falls in May and harvest runs from October to November. The region's hot Mediterranean summers (regularly above 40 °C) would make olive growing impossible without the Alqueva reservoir. The drip-irrigation system is the linchpin of the entire operation, and its performance determines the crop outcome each year.

## Satellite monitoring insights

Because the hedgerows are dense and irrigated, NDVI runs higher than traditional olive groves (0.4–0.6), with a clear seasonal cycle that peaks in late spring and holds through summer. EVI and SAVI are useful here because the rows are closed-canopy — standard NDVI saturates less easily at these densities. Drought stress is mostly an irrigation management issue: NDMI tracks whether the drip system is keeping up with the heat, and a falling NDMI in July or August is a direct readout of inadequate irrigation before yield is lost.

## Key metrics

| Index | Typical range | What it reveals |
|-------|--------------|-----------------|
| NDVI | 0.4–0.6 | Canopy density — higher than traditional groves |
| NDMI | −0.1 to 0.3 | Irrigation performance — the critical management index |
| EVI | 0.3–0.5 | Performance in dense-canopy hedgerows |
