GIS and Climate Change
Geographic Information System (GIS) Unit
The GIS unit is a component of Research Support Services in the Research and Technology Development Services (RTDS) Programme.
Apart from undertaking and supporting research needs in RTDS, the GIS provides a broad range of functions and services, many of which are transversal in nature. We work in a very dynamic and fast-evolving field which also encompasses technologies such as Remote Sensing, Global Positioning Systems (GPS) mapping, Spatial Web and dashboard development and the development of various spatial models and analytical tools. We also manage and provide access to a newly established weather-monitoring network spread across the province – one of the recommended actions emanating from the SmartAgri Programme.
The GIS at WCDoA had its origins in the mapping of natural and agricultural resources – strongly focused on soils, climate, water, vegetation and agricultural activities. Whilst these still comprise a large part of our activities and spatial database, the scope of GIS and its spatial data has become all-encompassing, having being identified as a key (and mandated) component of national development planning at all levels of government.
To this end the GIS unit manages and provides access to the detailed land use data from the WCDoA “Flyover” – a detailed field-level observation census of cultivated land conducted every 4 to 5 years, indicating the “footprint” of agriculture in terms of crops and infrastructure. We work closely with other provincial departments, as well as liaising with national Department of Agriculture, Land Reform and Rural Development. We are also required to conform to the requirements of national spatial legislation specific to governmental GIS facilities and operations.
The GIS unit is nominally structured into two overarching (and often overlapping) focus areas:
- The Research and Development component, focused on developing spatial technologies, undertaking research projects and analytics leveraging the application of GIS and associated technologies for agriculture. This component guides the strategic development of WCDoA’s agricultural GIS in the Department and province. (Dr Mike Wallace)
- The GIS Services component, providing support to a wide range of stakeholders, clients and government officials, often on an ad-hoc This support can be in the form of maps, Web applications, data extraction and analysis – and even rapidly deployed spatial apps and dashboards, where appropriate. (Francois Koegelenberg).
- We have 2 GIS Technicians at Elsenburg (Liezl McKenzie and Ronelda Jacobs) and 2 GIS Operators working from Worcester and Bredasdorp respectively (Wilanie de Villiers and Esther Wessels).
The unit is responsible for the maintenance and development of the formidable and ever-growing provincial spatial database. Many of our key datasets are made available for viewing in the popular CapeFarmMapper application which also provides limited analytical and mapping capabilities to stakeholders.

Climate Change: SmartAgri is the Western Cape’s coordinated climate change response for agriculture, providing a practical roadmap to build sector-wide resilience through partnerships, priority projects, research and governance.
The SmartAgri Plan, launched in May 2016, is the Western Cape’s sectoral climate change response for agriculture, guided by the vision “Leading the way to a climate-resilient agricultural future for the Western Cape.” Recognised as one of the strongest agricultural plans in the sector, it positions agriculture as the first provincial sector to benefit from a dedicated climate change response framework due to its high vulnerability. The Western Cape Department of Agriculture (WCDoA) leads coordination and implementation, with a renewed focus since January 2021 on deepening climate resilience across the sector.
Implementation actions included the appointment of Prof Stephanie Midgley as specialist advisor (from September 2016, for 24 months), extensive stakeholder engagement, and ongoing sector communication through the SmartAgri Barometer e-newsletter (published since 2017). Governance was strengthened through a SmartAgri Steering Committee and joint work with WC DEA&DP, which issued climate change advisories for municipal Integrated Development Plans. The plan was tested during the 2015–2018 “Day Zero” drought, which caused losses of 200 000 tonnes of wheat, 230 ha of potatoes, 15% of fruit, and left ±17 000 cattle needing fodder assistance. A Provincial Drought Dialogue in June 2016 led to a priority action plan aligned with SmartAgri objectives, developed with Agri Western Cape and AFASA.
Research and innovation form a core pillar, with SmartAgri-aligned projects led by WCDoA scientists, increased postgraduate research, and the development of climate-smart tools such as drones and Cape Farm Mapper. Priority projects include Conservation Agriculture, Integrated Catchment Management, and support for smallholder farmers through the Climate Resilience Project (2017–2019) with GreenCape. WCDoA also supports the GreenAgri portal as a sector-wide resource. Public awareness was strengthened through the “Die Kwik Styg” radio series on RSG (2018–2020), with selected episodes published as a multilingual e-booklet in 2021. An external evaluation (2019–2020) resulted in seven recommendations, addressed through a Management Improvement Plan following Prof Midgley’s appointment as Scientist for Climate Change and Risk Assessment in January 2021.
The SmartAgri project was a collaboration between WCDoA, WC DEA&DP and UCT’s African Climate and Development Initiative (ACDI), implemented in three phases (2014–2015). It produced the SmartAgri Plan, Status Quo Review, regional and commodity briefs, and case studies. The Status Quo Review assessed 23 agro-climatic zones, identified key climate trends, and serves as a practical decision-making tool, with updates released in 2016 and 2022. The Plan aligns with the Western Cape Climate Change Response Strategy (2014), the Provincial Strategic Plan (VIP2: Economy and Jobs), and the Minister of Agriculture’s priorities. It is guided by four strategic focus areas: climate-resilient production systems, disaster risk management, data and research, and cooperative governance.
