Job Description

The lack of field boundary maps is a major problem facing African agriculture. Field boundary maps do not exist for most African countries because of the logistical challenge and expense of collecting such data in the field. The importance of these field boundary maps cannot be overlooked as they provide the foundations for understanding the characteristics and extents of agricultural systems and for a broad swathe of the agricultural sector, and for society in general. To create field boundary maps in any realistic timeframe the only tool used is satellite remote sensing, but the small sizes and dynamic nature of smallholder fields make them hard to map correctly. Presently, there are no openly available field boundary labels that cover Sub-Saharan Africa’s broad range of agricultural systems. Existing label sets are also not suited for mapping field boundaries, as they are either point-based, cover very small regions, or are categorical. To address these critical issues there is an urgent need to develop field boundary labels that represent the entire region and span several years. This project will address the pressing need for comprehensive field boundary labels. It will include label fields in 54,000 high-resolution images collected across Sub-Saharan Africa during the primary growing seasons of 6 years (2017-2022).

The Lacuna project is being implemented by Farmerline together  with Spatial Collective  and Clark University.

Farmerline is the fastest growing Agtech company in Africa with a recent pre-Series A funding of $14 million led by Acumen Resilient Agriculture Fund (ARAF), Oikocredit and FMO, the Dutch entrepreneurial development bank and nine other global investors.

We are a learning organization and you will have the chance to apply your ideas and creativity to solve problems every day.  If you work well in a dynamic collaborative culture, set high standards, and meet challenges with determination and a sense of humour, you’ll thrive at Farmerline. We are an Equal Opportunity Employer. We value diversity and encourage applications from all candidates. We believe that diverse perspectives help our teams to create innovative solutions and understand our global clients’ needs. In alignment with our values, we are committed to recruiting and retaining a diverse global workforce without discrimination.
