We beleve in…

the natural system

NECTAERRA provides high-end consulting, monitoring and training in hydrology, farming, and agroforestry for a more sustainable and equal world.

What we do

Nectaerra supports clients and landowners to maximise the performance of water and land assets in areas with water and salinity problems. With technical innovations or sustainable, regenerative solutions that are financially and ecologically superior.


Sustainable water resource management from a system and earth science philosophy for cost-effective solutions that benefit people, planet and long-term resilience.

  • Groundwater and urban water fieldwork, analysis, modelling, and advice
  • Urban water management.
  • Drought, salinization, and farm water studies.


Transforming agriculture and land use towards financial and ecological sustainability with tools and techniques benefitting soil health, biodiversity, resilience and carbon sequestration. 

  • Design, implemention & monitoring of regenerative agriculture, agroforestry and soil restoration.
  • Drought and salinity mitigation.
  • Customized cover-companion crop seeds.

Why do we do that?

Our future requires a different way of looking at business cases and solutions. Approaches that preserve natural assets, constructions and profitability, and prevent side effects like drought, salinity, and land degradation. Local sustainable solutions for impact, biodiversity, climate and income resilience, and a healthy and safe living environment.


We work on projects that deliver sustainable solutions to a wide range of challenges. This work promotes sustainability, innovation, and collaboration in order to have a positive and lasting impact. Read about our projects.

First agroforestry farm- Egypt

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.

Saline groundwater mapping and risk prediction- Netherlands

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.

Future Farm model- Netherlands

The study assessed the ways in which conventional farms in The Netherlands could best be transformed to sustainable, commercial farms, highlighting the technical and commercial challenges, solutions, and priorities for various crops and soil types.
