Understanding the Concept of Food Sovereignty Using the Ghana School Feeding Programme (GSFP)
This article deepens the understanding of the emerging food sovereignty concept using a case study of a home-grown school feeding programme that promotes local food demand supply linkages. A school feeding programme in four selected districts in Ghana is analysed with respect to community involvement in programme implementation and management as well as its socio-economic impacts. -
Application of Radial Basis Function Network with a Gaussian Function of Artificial Neural Networks in Osmo-dehydration of Plant Materials
The study presents a critical evaluation of Artificial Neural Networks (ANNs) in food processing by successfully predicting the mass transfer in three plant materials. The used of ANNs in osmo-dehydration was evaluated using two varieties of apple (Malus domestica Borkh) of Golden Delicious and Cox, banana cultivar Cavendish and potato (Solanum tuberosum L.) variety Estima. -
Leaf resorption efficiency in relation to foliar and soil nutrient concentrations and stoichiometry of Cunninghamia lanceolata with stand development in southern China
Purpose The relationships among resorption, leaf nutrient status, and soil nutrient availability remain unresolved. Moreover, the dynamics of resorption in leaf and soil nutrients and stoichiometry during development of Chinese fir (Cunninghamia lanceolata) stands have rarely been studied. -
Geochemical Assessment of the Impact of Mine Tailings Reclamation on the Quality of Soils at AngloGold Concession, Obuasi, Ghana
This study assessed the geochemical impact of mine tailings reclamation on the quality of soils from the AngloGold Concession, Obuasi, Ghana. Soil samples from mine tailings reclamation sites were evaluated for the concentrations of plant nutrients and trace metals. Contaminations of trace metals, using geochemical pollution indices were used to assess possible effects on agriculture and livelihoods. The average pH ranges from 7.6 to 8.4 at the ex-tailing sites while the control site is 6.0. Organic carbon and nitrogen levels at the extailings site are low due to topsoil loss. -
Geosensors to Support Crop Production: Current Applications and User Requirements
Sensor technology, which benefits from high temporal measuring resolution, real-time data transfer and high spatial resolution of sensor data that shows in-field variations, has the potential to provide added value for crop production. The present paper explores how sensors and sensor networks have been utilised in the crop production process and what their added-value and the main bottlenecks are from the perspective of users. -
Introduction to Forests, roots and soil carbon
Below-ground components including roots are key contributors to the total forest ecosystem biomass and productivity. -

Litterfall production and nutrient return in different-aged Chinese fir (Cunninghamia lanceolata) plantations in South China
The amounts of litter produced and nutrients returned play a fundamental role in the productivity and biogeochemical and nutrient cycling of forest ecosystems. -
Effect of fermentation method, roasting and conching conditions on the aroma volatiles of dark chocolate
The combined effect of two cocoa fermentation methods – heap and tray – and different roasting and conching conditions on aroma compounds of dark chocolate were investigated. Dynamic headspace sampling/gas chromatography-mass spectrometry (GC-MS) was used to isolate and identify aroma volatiles. -
Physicochemical properties and sensory attributes of local snacks fortified with powdered fish processing by-products and an underutilized fish species.
Fish processing by-products and small pelagic fish could provide minerals and protein in diets of vulnerable populations as these could be more affordable than seafood. The study objectives were to determine the proximate nutrient content of tuna processing by-products and burrito fish and also assess the acceptability of fish powder-fortified local carbohydrate snacks.
