| The recent surge in food prices around the world may reverse the gains of reducing hunger and poverty in the recent years. This paper employs factor and sequential typology analysis using data for 175 countries to identify groups of countries categorized according to four measures of food security: utilization, availability, accessibility and stability. Nine indicators are used for this study: calories intake, protein intake, fat intake, food production, the ratio of total exports to food imports, soil fertility, length of growing period, coefficient of variation of length of growing period and urbanization. The analysis first identifies 5 distinct food security groups characterized by food intake then further split these groups based on similarities and... |

| The purpose of this paper is to provide a conceptual framework that can be used by agricultural leaders, administrators, policy makers, and seed program managers to (1) understand key factors affecting seed system development; and (2) compare organizational and institutional strategies for increasing seed system effectiveness. A literature review of recent studies on seed system development in Sub-Saharan Africa (SSA) was undertaken to achieve these objectives. The studies reviewed included published and unpublished reports, monographs, and case studies. |

| The motivation for this workshop came from two sources. First, under a project funded by USAID (AFR/SD/PSGE/TDT Office), Michigan State University (MSU) has been carrying out various activities to assist African national agricultural research systems (NARS) and regional organizations to improve their capacity for strategic agricultural research planning, including technology assessment and priority setting within a commodity sector framework. Second, recent collaborative work by the International Service for National Agricultural Research (ISNAR) and the Kenya Agricultural Research Institute (KARI) has focused on the development of a process and methods for program-level priority setting. The objectives of the workshop were (1) to provide a forum for... |

| Objetivou-se estudar a dinâmica dos carboidratos e a fluorescência da clorofila a em folhas de limeiras ácidas 'Tahiti', submetidas a épocas diferentes de anelamento e incisão anelar de ramos. Foram estudadas quatro épocas de realização de anelamento e incisão anelar, com um tratamento adicional, sem interrupção do floema. O anelamento, independentemente da época de realização, aumentou os teores de amido (55 a 90%) e açúcares solúveis totais (8 a 18%) nas folhas do 'Tahiti' até por volta dos 50 aos 60 dias. A incisão anelar, independentemente da época de realização, aumentou a concentração de amido (10 a 35%) em relação à testemunha, porém, o aumento foi inferior ao que ocorreu nas plantas aneladas (55 a 90%). O anelamento promoveu aumentos de F0 e... |
