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
Ce rapport final dresse le bilan des activités scientifiques engagées dans le cadre du projet Adap’Terr « L’adaptation au changement climatique : les défis d’une approche intégrée pour les territoires ? ». Ce volume de synthèse, présentant les principaux résultats, s’organise en trois parties. Une première partie précise certaines questions que posent pour l’aménagement et l’urbanisme l’action climatique locale, afin de développer un cadre conceptuel en mesure d’analyser les initiatives locales face au « problème climat ».
African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa can feed itself in a generation and help contribute to global food security. To achieve this Africa has to define agriculture as a force in economic growth by: advancing scientific and technological research; investing in infrastructure; fostering higher technical training; and creating regional markets.
Land and property rights, migration, and citizenship are complex issues that cut across all social, economic, and political spheres of West Africa. This paper provides an overarching scoping of the most pressing contemporary issues related to land, migration, and citizenship, including how they intersect in various contexts and locations in West Africa. The way issues are analytically framed captures structural challenges and sets them against the regional and global meta-trends of which policy makers and practitioners should be aware for conflict-sensitive planning.
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.
This brief summarizes a report on the first large survey of maize traders in Nigeria in the past several decades. The sample of about 1400 traders covered one state in the South and four in the North, with traders in city wholesale markets in the North (Jos, Kaduna, Kano, Katsina) and South (Ibadan) and regional markets in secondary cities in the North.
The cassava system in Nigeria is developing, with increasing attention to its potential positive outcomes. However, credit access is a major problem in expanding productive activities of the different actors across the value chains of cassava products. This study investigates the extent of access to credit by cassava actors with respect to the different financial institutions in the country using data obtained from a sample of 168 actors, including producers, processors, marketers, fabricators and end users
This synthesis report presents the outputs of the workshop organised by CTA at its headquarters in Wageningen, The Netherlands, 15-17 July 2008. The outputs are presented in two main parts, each corresponding to one of the workshop objectives, and ends with a section on the way forward as suggested by the workshop participants. It also includes a first attempt to come to a consolidated generic framework on AIS performance indicators, based on the outputs of the different working groups.
This paper examines different practical methods for stakeholders to analyse power dynamics in multi-stakeholders processes (MSPs), taking into account the ambiguous and uncertain nature of complex adaptive systems. It reflects on an action learning programme which focused on 12 cases in Africa and Asia put forward by 6 Dutch development non-governmental organizations (NGOs).
This review studied a selection of projects from the Research Into Use (RIU) Africa portfolio: the Nyagatare maize platform in Rwanda; the cowpea platform in Kano state, Nigeria; the pork platform in Malawi, the Farm Input Promotions (FIPS) Best Bet in Kenya, and the Armyworm Best Bet in Kenya and Tanzania. For each of the selected projects, assessments were made on how it changed the capacity to innovate, the household level poverty impact, whether the intervention off ered value for money, and what were the main lessons learned.
