Communication is essential to making biotechnology and genomics relevant to developing countries and poor people. Few would disagree with that. But many are sceptical about public relations efforts to impose inappropriate technological ‘solutions’ on developing countries. This paper is a partial reflection on how PR and advocacy ‘mixes’ can be understood and whether they can be useful to innovation in developing country contexts.

Traditional shifting cultivation in the Amazon region has caused negative environmental and social effects due to the use of fire. This type of agriculture has been criticized because it results in emission of large amounts of carbon into the atmosphere and a loss of soil productive potential.

African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.
