Thesis title

Spatial-temporal explicit scenario simulation of food and biomass fuel yield dynamics in savanna rural landscapes: a case study in northern Ghana

Thesis abstract

Most of African economies are strongly based on biomass production. The potential of its land to increase the volume of production (by improved seeds, fertilizer management, reduced tillage, optimization of rotational periods, etc…) has being widely evidenced. Furthermore, technological innovations to loose pressure on lands by means of increasing biomass-to-energy conversion efficiency are also continuously developed. Nonetheless, adoption of these improvements is slow and limited due to socio-economic reasons and the uncertainty about the success of innovations because frequently they cannot be easily up-scaled and successfully implemented in any type of agricultural system/region.

This uncertainty regarding the actual impact on regional food security of managerial and technological improvements and land use policies, might be better understood if they are evaluated by the definition of future scenarios through a regional lens. The baseline-data are existing land use maps that discriminate a variety of annual crops. Transition probabilities are estimated from recent land use changes and regional policy plans for the near- and mid-term.

Alternative future landscape configurations are described based on differentiated assumptions about the level of success of policy plans, and the range of biomass provision is drawn up by differentiated assumptions on future agricultural and forestry productivity.

The suite of biomass-based products provided by agricultural land use types is calculated with process-based models. Wood provision at sustainable harvesting levels of both plantation and non-plantation resources is based on extensive literature review on primary production, woodland growth and management methods. The results are presented as nutritional and fuel yields at the regional level, as well as a set of indicators of soil fertility trends.

With the scope on West African savanna agro-ecology, a region facing high socio-environmental risks, this research presents a case study in the Upper East Region of Ghana. The supply-demand analysis of food and energy, as well as environmental trade-off assessment, of alternative future landscapes will be good base to discuss the resilience of the region to face economic and environmental risks. The work-flow designed through this research may be a good guidance for similar analyses to support decision-making processes in regional planning
