Maize-Rice Cropping Systems in Bangladesh: Status and Research Opportunities
Provedor de dados: 31
Autores: Ali,   M. Yusuf; Waddington,   Stephen R.; Hodson,   Dave P.; Timsina,   J.; Dixon,   John.
Responding to demand from expanding poultry feed markets, maize area in Bangladesh rose from only a few thousand hectares in the 1980s to more than 200,000 hectares in 2007-08. This publication describes the rise of maize in Bangladesh, emerging problems or risks, technology options for rice-maize systems, and future research and development needs. It also outlines the role of CIMMYT, through its Bangladesh office, in the establishment and promotion of maize, as well as the provision of germplasm and capacity building for researchers and farmers, in collaboration with the Bangladesh Agricultural Research Institute (BARI), the Department of Agricultural Extension (DAE), and diverse non-governmental organizations.

The liberalization and restructuring of the seed sector in eastern and southern Africa (ESA) during the past two decades have witnessed a proliferation of private seed companies in the maize seed industry (Hassan et al., 2001; Lemonius, 2005). Although the total number of registered maize seed companies increased from 8 and 11, respectively, in 1997 to 40 each, the quantities of seed marketed barely doubled, increasing from 23,000 and 27,000 tons to 53,000 and 51,000 tons, respectively; an indication that the reforms are insufficient in ensuring efficient functioning of the sector in the two regions. A study involving 117 seed providers, representing 92 percent of all registered maize seed companies in ESA in 2007 identified bottlenecks that have...

Enriching Impact Assessment at CIMMYT
Provedor de dados: 31
Autores: La Rovere,   Roberto; Dixon,   John; Hellin,   Jonathan.
The International Center for Maize and Wheat Improvement (CIMMYT) is a CGIAR centre with a long tradition of impact assessment (IA). Until recently, such work had focused on the rates of adoption of improved germplasm and returns on investment. Limited attention was directed at measuring impacts in terms of livelihood security or poverty reduction. In 2005, therefore, CIMMYT's Impacts Targeting and Assessment Unit (ITAU) began to develop and promote more wide-ranging types of IA. In order to enhance its IA culture and institutionalize IA within the Center, ITAU organized a series of workshops that brought together different players amongst CIMMYT's staff and partners. Coupled with follow-up activities, these have made it possible for social and biophysical...

MONITORING SYSTEMS FOR MANAGING NATURAL RESOURCES: ECONOMICS, INDICATORS AND ENVIRONMENTAL EXTERNALITIES IN A COSTA RICAN WATERSHED
Provedor de dados: 31
Autores: Hazell,   Peter B.R.; Chakravorty,   Ujjayant; Dixon,   John; Celis,   Rafael.
The worsening degradation of natural resources urgently requires the adoption of more sustainable management practices. This need has led to growing interest and investment in monitoring systems for tracking the condition of natural resources. Although grounded in concepts of sustainability, the application of monitoring systems has progressed little beyond the identification and measurement of large numbers of potentially interesting indicators. Most monitoring activities are also passive and do not lead to the changes needed to rectify the problems they identify. Too often monitoring becomes an end in itself and an expensive claim on public funds. This study is concerned with the design of monitoring systems that have direct relevance for the management...

An analysis of the bottlenecks affecting the production and deployment of maize seed in Eastern and Southern Africa
Provedor de dados: 31
Autores: Langyintuo,   Augustine S.; Mwangi,   Wilfred; Diallo,   Alpha O.; MacRobert,   John F.; Dixon,   John; Banziger,   Marianne.
The publication describes outcomes of a study conducted in 2007/08 to analyze the bottlenecks affecting the production and deployment of maize seed in eastern and southern Africa. The objectives of the study were to provide a better understanding of the factors limiting the production and deployment of improved maize seed in Africa, and to contribute to increasing the efficiency of variety release, seed production and seed dissemination for new drought tolerant maize varieties. The study identified a number of institutional bottlenecks affecting the maize seed value chain, in particular in the area of policy, credit availability, seed production, germplasm and marketing. To address these bottlenecks and improve the efficiency of seed production and...
