“…The field team visited the Techiman North District at the end of 2021, and they took georeferenced photos which were later integrated into the suitability map. During the field trip, interviews were conducted with 34 farmers and five extension officers (Derkyi et al, 2021).…”

Water related problems caused by climate change are threatening the future of food systems in both Netherlands and Ghana. In this paper we present the results of a comparative case study analysis. The objective is identifying similarities in the use of spatial information by experts and stakeholders in their attempts to remove the barriers or foster the enablers of NbS uptake in view of climate change. Experiences in this field have been listed in the Rhine-Scheldt Estuaries (the Netherlands) and Bono East Region (Ghana) about rainwater harvesting and reuse of wastewater. The analysis focused on identifying similarities in the use of spatial information by stakeholders in their attempts to remove the barriers or foster the enablers of NBS uptake. Both rainwater harvesting and wastewater treatment techniques are available, and ready to be accepted and applied by farmers and food processing industry. Their uptake however is hampered by multiple barriers, ranging from biophysical and technical barriers to social and institutional barriers. We conclude that spatial information can be an enabler for adoption of nature-based solutions, if the spatial information is applicable for the assessment of a wide range of possible solutions for water scarcity considering food production, either nature-based solutions or technologies. In both case studies we observe a struggle to make the future spatially explicit. In both case studies, the effect on biodiversity of respectively reuse of effluent water and RWH did not play a direct role in the stakeholder dialogue.

“…Today, engineering inventions make it possible to have agricultural machinery designed with controlled traffic measures for cost-effective and energy-saving farm operations without tilling the soil unnecessarily (Patel et al, 2018). In sub-Saharan Africa, some successes have been chalked in the soil and water conservation research space; some of which include reduced tillage practices, high organic residue recycling agriculture, efficient irrigation practices, and even the improvising of simple water harvesters (Linderhof et al, 2022) among others. However, there seems to be a wide gap between research successes and actual implementation in farmer fields.…”

Complex controls and non-linear responses of the climate system to global warming make it difficult to have clear-cut predictions of future precipitation amounts and timelines. It is, however, evident from current observations that some predictions of unusually high rates of flooding and droughts are occurring and threatening food security in sub-Saharan Africa (SSA). The impact of climate change is immense on SSA though it contributes the least to climate change globally. Crops face lots of growth challenges which reduce their productivity under drought and flood conditions. SSA must prepare agricultural soils for the anticipated climate variabilities, to ensure sustainable food availability. The effort to adapt soils to climate change must be a concerted one, using technologies from various facets of science. Stakeholders must adopt water-smart strategies that maintain proper soil-water balance. They should focus on manageable inherent soil properties that control the susceptibility/adaptability of cropping systems to climate change. Conservation agriculture techniques that target improving soil organic matter and maintaining soil life; protecting the soil from compaction and erosion; reducing soil disturbance; enhancing soil infiltration and groundwater recharge capacity, must be applied to our soils. A number of these techniques equip the soils to be better sinks of excess water in flood-prone areas and improve water-holding capacities in drought-prone ones. Governments, farmers, and all stakeholders must also invest in both simple and complex water harvesting/ re-directing infrastructure which conserve water for future use. Water-efficient irrigation systems must be employed by farmers during water scarcity. Most importantly, gaps between research, industry, farmers, and governments must be bridged to for easy flow of information on improved technologies and quick adoption of climate change mitigation strategies.

“…Het is de grootschalige implementatie ervan wat de uitdaging vormt. Wageningse onderzoekers proberen momenteel in de Oost-Afrikaanse regio Bono East landbouwondernemers aan de hand van klimaatvoorspellingen en voedselsysteemanalyses te overtuigen om te investeren in regenwateropvangsystemen (Linderhof et al, 2022). Stakeholderparticipatie is een essentieel onderdeel van deze strategie.…”
