| The publication describes outcomes of a study to assess the effectiveness of a large-scale crop seed relief effort in Zimbabwe during 2003-07. Aims of the effort, which was supported by the British Department for International Development (DfID) and coordinated by the Food and Agricultural Organization (FAO) regional office in Harare, included broader diffusion of open-pollinated maize varieties (OPVs), as opposed to hybrids. Based on the findings of the study, the authors recommend that, to increase benefits to vulnerable groups, participants in such efforts should effectively disseminate information on selecting and recycling seed, supported by training and field demonstrations, and should target relatively well-endowed farmers initially. Recommendations... |

| The amount of energy and food consumed in Puerto Rico is more indicative of a developed nation than one than is underdeveloped. All the energy consumed in Puerto Rico is from fossil fuels, while the agricultural sector marginally provides the needs of the consumer. In addition, the animal production sectors rely exclusively on imported feedstock for the preparation of feeds. There is a potential to develop an ethanol industry based initially on sugarcane, as the main feedstock and then turn to biomass from energy cane and or organic solid waste in the future. In order to move to the second generation of ethanol production, the cellulosic ethanol industry has to become economically viable. A limiting factor in the use of sugarcane is that only 40,000 ha are... |

| Professionals involved in animal and plant production chains are currently confronted with a scenario of contradictions. There is a growing demand for food, on the other hand, social pressures question how food is produced. Within this context, integrated production systems could be an important strategy. Integrated crop-livestock systems (ICL) consists of the implementation of different systems for animal and agricultural production in the same area, planted concurrently, sequentially or in rotation. The most reported advantages of ICL systems are agronomic or productive benefits, which are the result of improved soil quality and better pest control. However, to implement ICL systems on large scale, representing an actual alternative for food production,... |

| This paper presents a case study of resilience theory to understand agricultural systems in the Luancheng County of the North China Plain. A dynanic system model coupled with social, economic and ecological subsystems of agriculture for the Luancheng County was constructed with a time step of one month. The model includes five main components, water resources, profitability, irrigation, crop yield and area. The simulated groundwater table, wheat area and yield, maize area and yield, and rural labor transfer reflected the general trend of the observed data, with calculated determination coefficients higher than 0.88. Resilience of agricultural systems, as indicated by agricultural profitability and food security, were explored for the Luancheng County.... |
