This paper examines the literature on how biodiversity contributes to improved and diversified diets in developing countries. We assess the current state of evidence on how wild and cultivated biodiversity in all forms is related to healthy diets and nutrition, and examine how economic factors, knowledge and social norms interact with availability of biodiversity to influence both production and consumption choices.

The agriculture sector has great potential to contribute to the mitigation of greenhouse gas emissions through changes in agricultural management and land use. However, the technical potential for agricultural mitigation has yet to translate into actual emission reductions due to considerable constraints to the generation of emission offsets through agricultural projects.

Innovation platforms are a development tool used increasingly to support the stakeholders in complex systems for agricultural development in developing countries. This article presents the results of a study measuring the impact of innovation platforms on improving agricultural production for the beneficiaries of a project in Yatenga province, northern Burkina Faso. This innovation platform was installed in 2011 as part of the activities of the Volta2 project, operating jointly in Burkina Faso and Ghana.

The various ways in which livestock production systems can be incorporated into economic, partial-equilibrium, multi-market models are presented, and the challenges outlined. A particular focus and illustrative case is livestock feed. Foremost among the challenges is the reconciliation of scientific understanding of livestock feed requirements and production characteristics with the available national data. Another challenge is in estimating herd structures.

The thesis of this paper is that the "rational fool" syndrome can be applied to mainstream public sector agricultural research that is conducted in a way that is rational in the short term, but acts against its own long-term viability. Historically, a main concern of such research has been to maximize high levels of food production together with low prices to consumers. As a result, mainstream agricultural science has ignored negative impacts or externalities, which has contributed to a crisis of credibility with the general public and politically sensitive decision makers.

This Working Paper summarizes research conducted as part of the AgWater Solutions Project in Ethiopia between 2009 and 2012. Researchers from the AgWater Solutions Project conducted a situation analysis in 2009, which identified a range of options deemed to be technically feasible, affordable and practical for smallholder farmers: water-lifting technologies, groundwater for agriculture and manual well drilling, community-based watershed management, on-farm water storage, small reservoirs and rainwater harvesting.

This Working Paper summarizes research conducted as part of the AgWater Solutions Project in Zambia from 2009 to 2012. Approximately 48 million hectares (Mha) of land in Zambia are suitable for agricultural use. An estimated 67% of the Zambian labor force is employed in the agriculture sector. Researchers from the AgWater Solutions Project examined ways of improving the motor pump supply chain, how to make better use of small reservoirs and improving the function of horticultural markets. Researchers also explored gendered aspects of agricultural systems.

This introductory chapter sets the scene for the discussion in the edited volume on how new agricultural affects tropical forests. It critically reviews four hypotheses that have been central in the claim that better technologies help protect forests: the Borlaug, the subsistence, the economic development and the land degradation-deforestation hypotheses. Each of them appears to be valid only under certain restrictive conditions. The chapter then gives the aims and scope of the book, the key conclusions, as well as a summary of each of the chapters.
