Un problema que enfrenta la producción nacional de madera aserrada es la pérdida de competitividad frente a la madera importada. Para el periodo 1993-1995, la producción nacional abastecía el 80% del consumo nacional y para el 2001-2003 sólo el 3%. Con el objetivo de determinar los factores que podrían revertir esta tendencia, se usó un modelo de programación no lineal
This study focused on analysing the determinants of farmer participation in direct marketing channels using the case of the cassava sector in the Oyo State of Nigeria. The Bivariate Tobit model was applied in the empirical analysis, based on a primary dataset generated from 400 rural cassava farmers from the Oyo State of Nigeria. The main objective of this study was to analyse the effects of the determinants of farmer decision to either participate in the processor or middlemen marketing channels in the Oyo State of Nigeria.
La presente investigación tiene como objetivo desarrollar el análisis de las tendencias de investigación como una práctica internacional de obligatorio cumplimiento para el caso de las actividades de I+D, donde el conocimiento del entorno tecnológico propende por sustentar y justificar la inversión de recursos humanos y materiales en distintos proyectos de investigación, a partir de la vigilancia tecnológica como herramienta de direccionamiento estratégico.
This study examines the price transmission mechanisms in the Bloemfontein beef market using the producer price and retail prices at four retail outlets collected over a period of 3 years. It further estimates the causality links between the producer and retail prices. The traditional (Engle-Granger) and standardized (Enders & Siklos) Augmented Dickey- Fuller procedures were used to test for co-integration and asymmetry in price transmission
This work has largely focused on the developed world, yet the majority of people and future economic growth lies in the developing world. Further, most research examines micro data on consumers or firms, limiting what is known regarding the role of macro factors on diffusion, such as social systems. Addressing these limitations, this research provides the first high-level insights into how green building adoption is occurring in developing countries.
In this article, wes developed a quantitative model to compare HT and CF supply chain finance schemes with each other and with traditional, fixed-price delivery contracts, which we identify as Soft Tolling (ST). We make this comparison in the setting of a three-echelon agricultural supply chain, where the third echelon is a large, creditworthy food/beverage manufacturer. This article proceeds as follows: the next section discusses related literature. Section 3 presents our model of an agricultural supply chain and the three specific contract variants (ST, HT, or CF) that we study.
In this paper the authors used a network perspective to study the micro level of agricultural innovation systems and investigate the different roles and functions that collaborating actors have to perform to spread their innovation both horizontally and vertically. Based on a literature review, we distinguish between three separate network functions: (1) learning and knowledge co-creation, (2) upscaling and institutional entrepreneurship and (3) outscaling and innovation brokerage.
This paper studies the relationship between the Women’s Empowerment in Agriculture Index (WEAI) and market orientation of farm production in India. This is the first time that the WEAI has been used in an Indian agricultural context and the first time that it is being associated with market orientation. Was used data on 1920 adults from 960 households in the Chandrapur District of Maharashtra and classified the households into three groups—(1) landless, (2) food-cropping, and (3) cash-cropping—that reflect increasing degrees of market orientation
The nature of interactions between farmers and advisors is the focus of a growing body of research. While many studies explore the potential role of advisors in facilitating farmers' practice change in practices related to agricultural production such as soil, water, pest and animal health management, studies that specifically investigate how advisors support farmers with financial management (FM) are limited. The contribution this paper makes is to identify who farmers' FM advisors are and to shed light on how farmer-advisor interactions about FM are shaped.
One option for practically applying innovation systems thinking involves the establishment of innovation platforms (IPs). Such platforms are designed to bring together a variety of different stakeholders to exchange knowledge and resources and take action to solve common problems. Yet relatively little is known about how IPs operate in practice, particularly how power dynamics influence platform processes.This paper focuses on a research-for-development project in the Ethiopian highlands which established three IPs for improved natural resource management.
