In sub-Saharan Africa, there is increasing interest for the adaptation and use of the innovation systems approach to advance learning and development in the Agricultural Research and Development (ARD) sector. This crave is constrained by unavailability of a proven blue print that describe the paradigm shift from the linear approach and how such could function under different socio-economic, cultural and political climate.
In order to address food insecurity, the New Green Revolution for Africa (GR4A) promotes tighterintegration of African smallholder farmers, especially women, into formal markets via value chains to improve farmers’ input access and to encourage the sale of crop surpluses. This commentary offers a theoretical and practical critique of the GR4A model, drawing on early findings from a five-year study of value chain initiatives in Burkina Faso, Côte d’Ivoire, and Mozambique.
Fairtrade certification has recently gained in importance for various export crops produced in developing countries. One of Fairtrade's main objectives is to improve the social conditions of smallholder farmers. Previous research showed that Fairtrade has positive effects on farmers' sales prices and incomes in many situations. However, more detailed analysis of the effects on food security and other dimensions of household living standard is rare.
It is often assumed that voluntary sustainability standards – such as Fairtrade – could not only improve the socioeconomic wellbeing of smallholder farmers in developing countries but could also help to reduce negative health and environmental impacts of agricultural production. The empirical evidence is thin, as most previous studies on the impact of sustainability standards only focused on economic indicators, such as prices, yields, and incomes.
This book documents a unique series of 19 case studies where agricultural biotechnologies were used to serve the needs of smallholders in developing countries. They cover different regions, production systems, species and underlying socio-economic conditions in the crop (seven case studies), livestock (seven) and aquaculture/fisheries (five) sectors. Most of the case studies involve a single crop, livestock or fish species and a single biotechnology.
One of the most important challenges for the researchers in the 21st Century is related to global heating and climate change that can have as consequence the intensification of natural hazards. Another problem of changes in the Earth's climate is its impact in the agriculture production. In this scenario, application of statistical models as well as development of new methods become very important to aid in the analyses of climate from ground-based stations and outputs of forecasting models. Additionally, remote sensing images have been used to improve the monitoring of crop yields.
Esa tesis doctoral tiene como objetivo general analizar el proceso de evaluaciónde impactos económicos, sociales y debido a la jeneración de intangibles de innovaciones generadas por centros públicos brasileños de investigación. Se justifica la elección de Brasil y de las innovaciones desarrolladas en el sector agrícola en razón de la importancia económica y social que tiene para el país el desarrollo de las actividades de este sector, que genera una de cada tres unidades monetarias del Producto Interno Bruto - PIB.
The rise of new powers in development has generated much debate on the extent to which South–South Cooperation (SSC) constitutes a new paradigm of development more relevant to African needs or a disguise for a new form of imperialism. This paper critically examines the rise of Chinese and Brazilian technical and economic cooperation in African agriculture with two cases drawn from Ghana and Mozambique.
Este artículo tiene por propósito comparar las redes de compras públicas para la agricultura campesina y familiar en los programas de alimentación escolar de los municipios de Granada (Antioquia-Colombia) y São Lourenço do Sul (Rio Grande do Sul-Brasil) en los años de 2016 y 2017. Para tal fin, se construyó un abordaje teórico-metodológico desde la perspectiva de las redes de política pública, articulado a dos metodologías, el Análisis de Redes Sociales y la comparación de Sistemas de Máxima Diferencia.
Genetically engineered (GE) foods apply new molecular technologies to Widely adopted in the United States, Brazil, and Argentina for the p corn, soybeans, and cotton, they are practically banned in Europe and tigh throughout the world. We have found that GE foods have significantly incr of corn, soybean, and cotton, and lowered their prices, thus improving food foods have already contributed to a reduction in the use of pesticides and
