The Kalkulator is a rapid ex-ante impact assessment tool with minimum data requirements that allows users to benchmark and explore multiple environmental impacts of interventions (e.g. productivity-enhancing agricultural practices, soil protection measures) on a farm using four indicators: greenh...

This paper presents the main features of a unique decision-support tool developed for selecting tree species in coffee and cocoa agroforestry systems. This tool aims at assisting in the selection of appropriate shade trees taking into account local conditions as well as needs and preferences of s...

Spatial distribution of soil nutrients is not normally considered for smallholder farms in Ghana resulting in blanket fertilizer application which leads to low efficiencies of some applied nutrients. This study focuses on applying geospatial analyses to map 120 maize farms in 16 districts of the ...

In most parts of West Africa, poverty contributes immensely to poor fertilizer adoption by smallholder farmers. Fertilizer adoption could be improved with micro-dosing technology. A socio-economic survey was conducted in the semi-deciduous forest zone of Ghana to assess the extent of fertilizer u...

The large diversity of farms and farming systems in sub-Saharan Africa calls for agricultural improvement options that are adapted to the context in which smallholder farmers operate. The socio-ecological niche concept incorporates the agro-ecological, socio-cultural, economic and institutional d...

The increased use of sustainability standards in the international trade in cocoa challenges companies to find effective modes of service delivery to large numbers of small-scale farmers. A case study of the Sustainable Tree Crops Program targeting the small-scale cocoa producers in Côte d’Ivoire...

Oil palm is an important industrial, livelihood and food crop in Ghana. Smallholders produce the bulk of the palm fruits and small-scale processors, mainly women, produce most of the crude palm oil. Poor practices lead to a high proportion of free fatty acids in the crude palm oil and the process...

Common bean and soybean yield poorly on smallholder farms in Rwanda. We evaluated the benefits of inoculation combined with P fertilizer and manure on yields of common bean and soybean in three agro-ecological zones (AEZs), and their residual effects on a subsequent maize crop. In the first seaso...

Grown by the ancient civilizations of the Andes, grains such as quinoa, cañihua and amaranth have been staple crops for communities across Bolivia and Peru for over a millennia. Agricultural practices have changed dramatically over the last decade, and poor rural farmers are cultivating these tra...
