The impact of global warming on crop growth periods and yields has been evaluated by using crop models, which need to provide various kinds of input datasets and estimate numerous parameters before simulation. Direct studies on the changes of climatic factors on the observed crop growth and yield could provide a more simple and intuitive way for assessing the impact of climate change on crop production.
This article addresses the impact of Integrated Agricultural Research for Development (IAR4D) on food security among smallholder farmers in three countries of southern Africa (Zimbabwe, Mozambique and Malawi). Southern Africa has suffered continued hunger despite a myriad of technological interventions that have been introduced in agriculture to address issues of food security, as well as poverty alleviation.
This paper investigates the effect of Plant Variety Protection (PVP) regulation on the governance of agri-food value chains (AFVC) with a small-scale survey of kiwi producers in Italy. We found that AFVC trading-protected (club) plant varieties are more likely to exhibit captive governance forms than those trading the free varieties. Nevertheless, the producers of club kiwis achieve higher returns from their investments and bear less risk than others.
Smallholder producers in sub-Saharan Africa are often unable integrate into markets and access high-value opportunities by effectively participating in global chains for high-value fresh produce. Using data from a survey of large avocado farmers in Kenya, this study examines the determinants and impacts of smallholder-producer participation in avocado export markets on labor inputs, farm yields, sales prices, and incomes, using a switching regression framework to control for selection effects
The report specifically analyses the NIS in Peru and Colombia in the coffee and dairy sectors due to their economic importance for both countries and the large percentage of small producers in these sectors. In order to analyse the NIS, we have utilised an innovations systems approach to form the analytical framework. This framework focuses on four main areas – understanding the actors in the NIS, their roles and attitudes, the patterns of interaction of these actors, and the enabling environment with a focus on small producer inclusion.
The innovation systems (IS) approach—developed by Richard Nelson, Christopher Freeman and Bengt-Ake Lundvall, amongst others—has become perhaps the dominant approach in the academic literature for the study of innovation. It has also exerted considerable influence on policy. This paper examines both the theory underpinning the IS approach, which bears considerable affinities with Austrian economics, and also its policy implications.
The aim of this paper is to characterise the innovativeness of individual farms in the Łódź region. Based on a domestic and foreign literature study, the most frequently used variables connected with farms (namely, the type of agricultural activity, economic size and VAT settlement system) were selected. The analysis of selected variables that characterise the innovative activity of the researched entities was carried out using the basic measures of structural analysis and interdependence of phenomena.
This policy brief deals with the following points: (i) Given the importance of agriculture and the rural medium for countries’ growth and development, policy makers must strengthen the institutional structure of rural extension and increase public and private investment; (ii) Abundant natural resources, knowledge, technology, and extensionists are not enough.
As the PAEPARD project is complex and multi-faceted, ensuring that appropriate information is made available to users in a timely manner and in a form that can be easily understood and used has been a major challenge.
This methodological framework is based on Life Cycle Assessment (LCA) and multi-criteria assessment methods. It integrates CSA-related issues through the definition of Principles, Criteria and Indicators, and involves farmers in the assessment of the effects of CSA practices. To reflect the complexity of farming systems, the method proposes a dual level of analysis: the farm and the main cash crop/livestock production system. After creating a typology of the farming systems, the initial situation is compared to the situation after the introduction of a CSA practice.
