Nectaerra designed the first agroforestry farm in Egypt at Sekem Farm and provides ongoing farming support. The agroforestry field consists of a wide variety of trees, bushes and annual crops, including cover crops. The system is expected to become self-supporting to a large degree by better soil fertility and stronger plants, reducing the needs for artificial inputs for fertilization and chemical protection. Nectaerra is the agroforestry partner in the PRIMA project with various universities in the EU that will continuously monitor and evaluate the developments.

Successful predicting saline groundwater intrusion into the surface water and soils in a residential area due to sewer works. Field work with cone-penetration tests including resistivity (outsourced), monitoring wells, infiltration and water quality tests, and soil classification. A 3D groundwater (SEAWAT) model was built including the civil infrastructure, with prediction of salinization and soil stability, and pumping requirements for artificial drainage.

Sorghum and wheat are among the most important crops grown in the Sahel countries. Using the soil-vegetation-atmosphere transfer model SWAP, we assessed how two scenarios of predicted climate change (in 2050 and 2100) would affect crop water demand for different locations with different soil types. The outcome showed how soil type plays a role, with climate scenarios leading to considerable differences in biomass growth.

Various exploration studies for new groundwater resources. Drilling (outsourced), geophysical logging and well sampling, geophysical modelling, electromagnetic surveying, seismic interpretation, petrophysical log analysis, geological and hydrological modelling, remote sensing, and GIS. New groundwater was discovered and delineated of recent and fossil (old) origin.
