Unpacking scaling in agricultural research for development: The role of social capital
2024
Martinez-Baron, Deissy | Gravsholt Busck, Anne | Prager, Steven D.
Agrifood systems are facing significant challenges, science and innovation are key to shift the trajectory towards ensuring sustainability and resilience. Thus, scaling assumes a critical role in agricultural research for development (AR4D). Scaling consists of a continuous process in which innovations are tailored, used, and embedded into societal dynamics adapted to various contexts, aiming to create widespread positive impacts. This systematic literature review explores scaling within the context of AR4D, with a particular focus on the role of social capital. Using bibliometric and factor analysis methods, we identified the intellectual structure in the field of scaling, revealing the knowledge domains and disciplines that have determined their emergence and growth as a scientific discipline. Then, we analyzed the role of social capital in the scaling literature. Our results showed that the field of scaling is composed by four distinct literature clusters: the innovation and adoption of agricultural technology, the economics of technology adoption, sustainability in agricultural innovations, and the emergence of scaling as a research field. Disciplines such as sustainable agriculture, systemic thinking, technological transitions, and technology adoption have contributed to the development of the field. The results indicate that the explicit consideration of social capital in the scaling literature within AR4D is limited despite the importance of relationships, trust, and reciprocity values in the process of scaling. This study highlights the continuous growth and multidisciplinary nature of scaling as a research field in AR4D, reflecting its complexity. International agricultural research centers and universities from developed countries have significantly advanced this field, also underlying the importance of locally rooted, and participatory research. Future research on the creation, development, and strengthening of social capital in scaling processes can contribute foster intentional and responsible scaling of AR4D innovations.

Influence of ecological factors on the pine increment dynamics in drained forests
2001
Indriksons, A. (Latvia Univ. of Agriculture, Jelgava (Latvia). Faculty of Forestry. Dept. of Silviculture)
The paper reports on annual pine increment dynamics during the period of last 30 years in the Vesetnieki Station of Permanent Ecological Research with a different drainage level: transitional bog, tree stand between the drainage ditches, tree stand adjacent to ditch. The increment of basal area of annual rings has been found to be considerably higher in the site adjacent to ditch with the most intensive drainage level. The increment of annual rings of individual trees proved to be non-synchronic, therefore trees can be suggested to have different response to have different response to the influence of the same meteorological factors (amount of precipitation, for example). The annual increment data for the last four years (1997-2000) have been compared to the results of biogenous substance circulation measurements during the given period.

2001
Skore, D. (Latvia Univ. of Agriculture, Jelgava (Latvia). Faculty of Food Technology. Dept. of Food Technology)
More and more people looking for healthy foods. Because researchers in nourishment to look for new possibilities in breadmaking. One of the possibilities is to substitute wheat flour by oat or buckwheat flour in bread products. Bread quality is characterized by sensory properties: taste, smell, flavour and texture. Hardiness, elasticity and gumminess are important indices of bread texture. The purpose of our work is to determine the changes in the bread texture of mix flour sample. Samples were prepared to substitute wheat at 10% and 15% or by at 10% and 25%. The wheat flour was used as a control. The experiments were made in the pilot Laboratory of I.A.T.A. in Spain, using AACC methods. Output data show that substitution buckwheat flour has improved the texture of bread, but substitution of oat flour has impaired the properties of texture.
