Argentine agriculture has undergone significant transformations over the past three decades. After a long period of stagnant production and productivity, starting in the early 1970s, a number of independent but interconnected events fostered a new technological cycle that induced rapid growth in cereals and oilseeds production. Zero tillage and the introduction of genetically modified soybean varieties were key elements of this change. Argentina reached a leading position across agricultural commodity markets.

This book examines how agricultural innovation arises in four African countries – Ghana, Kenya, Tanzania, and Uganda – through the lens of agribusiness, public policies, and specific value chains for food staples, high value products, and livestock. Determinants of innovation are not viewed individually but within the context of a complex agricultural innovation system involving many actors and interactions.

The paper aims to identify barriers to the development of Learning and Innovation Networks for sustainable agriculture (LINSA). In such networks, social learning processes take place, and knowledge about sustainable agriculture is co-produced by connecting between the different frames and social worlds of the stakeholders with the help of boundary objects. Studying such processes at the interface between different knowledge spheres of research, policy and practice requires a specific methodology.

This book contains a collection of papers that discuss the experience of an Agricultural Research for Development (AR4D) capacity building program in Papua New Guinea (PNG). The program was the AusAID-funded Agricultural Research and Development Support Facility (ARDSF), which ran for fi ve years from 2007 to 2012, and which sought to improve the delivery of services by agricultural research organisations to smallholder farmers. 

The turn of agrarian sciences and agricultural extension from reductionist and transfer of technology, respectively, towards systemic approaches has transformed agricultural/rural development thinking in the last decades. Nevertheless, the emergence of Agricultural Innovation Systems (AIS) has to confront a number of gaps among which the expert – lay knowledge gap is of major importance. This paper aims at exploring such a gap as well as obstacles to participatory development from a critical realist point of view.

This issue of the quarterly journal "Capacity.org" focuses on methods that can help to understand the societal context in which capacity development takes place. One of these methods is systems thinking, in which organisations, sectors and societies are seen as systems composed of elements that interact with each other. 

The Andhra Pradesh sorghum coalition illustrates the valued added by working in coalition. By combining different perspectives to give rise to new, synthesised ideas, the member organisations worked at a faster pace and achieved their objectives more successfully and sustainably than they could have done if working separately. The methodology of their research was designed collaboratively. As a result, scientists carried out repeat experiments on poultry, at the request of poultry farmers and feed manufacturers, which greatly increased their confidence in the evidence.

This volume is devided into three parts. The first part describes on-going
processes of change within, or aside, the socio-technical regime that we have
inherited from the modernisation and industrialisation process of agriculture,
which took part after the second world-war. The focus in this part is on studies
dealing with the issue of agro-ecological initiatives born in niches of organic
movement, which are questioning the mainstream regime of industrialised
agriculture.

This chapter documents the learning process within the framework of innovation of soil fertility management practices that emerged from the implementation of Participatory Extension Approach (PEA) as part of service delivery reorientation within the Limpopo Department of Agriculture in South Africa.The chapter gives a narrative description of what transpired during the interaction between researchers, extension officers and farmers, the processes involved, the lessons and the conclusion.

There is renewed attention on the importance of advisory services and extension in rural development processes. This paper, based on the publication ‘Mobilizing the potential of rural and agricultural extension', focuses on five opportunities to mobilise the potential of extension and advisory services. The five areas are: (1) focusing on best-fit approaches; (2) embracing pluralism; (3) using participatory approaches; (4) developing capacity; and (5) ensuring long-term institutional support.
