“…However, these soils are too acid in the subsoil on the Danish plantations for some varieties of coffee, especially arabica . However, as previously noted, the major limitation for coffee growth is the low amount of plant–available water, found to be as low as 10% by volume (Awadzi et al, 2001). The problem is compounded by the fact that many of the plantation soils are too shallow and the subsoils are too acid to allow optimum root development.…”

“…Although the Portuguese were the first to arrive in the Gold Coast, the Danish were the first European settlers to introduce plantation agriculture to the region as early as the late 18 th century (Yaro et al, 2016). The first Danish plantation was established at Amenapaso in Akronpong Akwapim, in 1788 (Awadzi et al, 2001). Subsequent to this, other plantations were established in the foothills of the Akwapim mountain range.…”

“…Subsequent to this, other plantations were established in the foothills of the Akwapim mountain range. The primary factor shaping the establishment of plantations was the production of export crops locally, and using slave labour to avoid the cost of transporting African slaves to the West Indies and Americas (Awadzi et al, 2001). Instead, the slaves became plantation labourers in the production of sugarcane, tobacco and other tropical crops, for export to Europe (Awadzi et al, 2001).…”

Instead, the slaves became plantation labourers in the production of sugarcane, tobacco and other tropical crops, for export to Europe (Awadzi et al, 2001).

“…However, on the basis of a range of socio-cultural and ecological factors, the Danish plantations failed to gain acceptance among smallholder farmers in the Gold Coast (Awadzi et al, 2001;Yaro et al, 2016). For example, the plantation system comprising mainly tree crops that required a long period of growth, and occupied the land for a long period, was inconsistent with native perennial cropping, and out of step with the local economy and social systems, as well as communal land tenure arrangements.…”

Agrarian transformation in Ghana’s Brong Ahafo region: Drivers and outcomes

Food and agricultural systems in the global South have undergone recent and significant transformation. Such changes are driven by an array of actors, and alongside social, political and economic forces, including a renewed investment by global development actors following the global agri-food crisis in the mid-2000s. The global agri-food crisis, in particular, is associated with speculations in food and agriculture, alongside the introduction of new modernisation policies and programmesincluding the Alliance for a Green Revolution in Africa. Such interventions are often couched as a response to the challenge of feeding the world's growing population, estimated to reach nine billion by 2050. In Africa, an agricultural transformation is also closely tied to initiatives to modernise agriculture, including expanding export-led agricultural development. Turning to Ghana in particular, market-based and export-led agricultural development policies and narratives have expanded since at least the mid-2000s, incorporating new actors, and extending their local level impacts. During this period, dominant agricultural development narratives framed Ghana's agrarian problems as largely technical and supply-side problems, which could be solved by increasing productivity as well as diversifying into production of export crops, thereby addressing poverty, food insecurity and global market access issues. In particular, the promotion of cashew nut production as export diversification has integrated farmers in the Brong Ahafo Region into the global commodity market. These market-based approaches are shaping agricultural practiceswith outcomes that are transforming agriculture in Ghana, particularly the Brong Ahafo Region. With this as context, this thesis adopts a critical political ecology approach to analyse contemporary processes and outcomes of agricultural transformation in Ghana's Brong Ahafo Region. Political ecology was adopted to render transparent the complex political, economic and sociocultural processes across different global and local scales shaping agricultural transformation in the region, often referred to as the 'breadbasket' of Ghana. The research adopts qualitative methods, including interviews, focus group discussions, observation and policy document analysis, to gather in-depth data on farming systems in the Brong Ahafo Region.

Accurate knowledge about factors and conditions determining copper (Cu) toxicity in soil is needed for predicting plant growth in various Cu-contaminated soils. Therefore, effects of Cu on growth (biomass production) of lettuce (Lactuca sativa) were tested on seven selected, very different soils spiked with Cu and aged for 2 months at 35 °C. Cu toxicity was expressed as pEC50(Cu(2+)), i.e., the negative logarithm of the EC50(Cu(2+)) activity to plant growth. The determined pEC50(Cu(2+)) was significantly and positively correlated with both the analytically readily available soil pH and concentration of dissolved organic carbon [DOC] which together could explain 87% of the pEC50(Cu(2+)) variation according to the simple equation: pEC50(Cu(2+)) = 0.98 × pH + 345 × [DOC] - 0.27. Other soil characteristics, including the base cation concentrations (Na(+), K(+), Ca(2+), Mg(2+)), the cation exchange capacity at soil pH (ECEC), and at pH 7 (CEC7), soil organic carbon, clay content, and electric conductivity as well as the distribution coefficient (Kd) calculated as the ratio between total soil Cu and water-extractable Cu did not correlate significantly with pEC50(Cu(2+)). Consequently, Cu toxicity, expressed as the negative log of the Cu(2+) activity, to plant growth increases at increasing pH and DOC, which needs to be considered in future management of plant growth on Cu-contaminated soils. The developed regression equation allows identification of soil types in which the phytotoxicity potential of Cu is highest.
