| Fruit flies are recognised as one of the major pests of fruit and vegetable crops worldwide. Potential benefits from fruit fly research include biosecurity benefits from better quarantine surveillance that reduces the costs of an incursion by a damaging exotic pest fruit fly; market access benefits by enabling new fruit exports; and field control benefits from better crop management. The Australian Centre for International Agricultural Research (ACIAR)’s investment in fruitfly research goes back some 25 years to an initial project in Malaysia. Since that time, ACIAR’s continued investment has funded a total of 18 projects ranging across several areas of fruit-fly research, and covering Malaysia, Thailand, Philippines, Fiji Islands, Samoa, Tonga, Cook... |

| A survey was conducted in Akure Local Government Area of Ondo State to give preliminary information on the magnitude, characteristics and contribution to rural employment of small-scale, wood-based processing enterprises through structured questionnaire. Small scale, wood based enterprise accounts for about 44% of the total rural labour force. The enterprises are characterized by very small size, heavy reliance on entrepreneur and family labour, technological simplicity of operations and rural location bias. Furniture, logging and carpentry were found to be the commonest among the small scale, wood-based enterprises. A range of problems facing small scale, wood-based enterprises was identified and a number of solutions were suggested. It was recommended... |

| 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... |

| Risk of establishment of the freshwater climbing perch (Anabas testudineus) in mainland Queensland from the Torres Strait is high. The species is dispersed through human assistance and/or attributes that assist its own spread. The species has the potential to out-compete native freshwater and estuarine species, and has sharp well-developed gill plates and spines that may choke and kill predatory species like barramundi if swallowed. The presence of climbing perch would severely impact Queensland’s inshore and freshwater fisheries, both commercial and recreational. The net present value of expected lost fishing activity due to build-up of the climbing perch is $48.5 million when the probability of introduction is 20 per cent. Analysis of potential spending... |

| Agricultural research in marginal dry areas can contribute to reducing poverty through the development of technological, institutional and policy options for poor farmers by addressing diversified opportunities and development pathways. This paper analyzes the diversity of rural livelihood strategies in the Khanasser Valley in northwest Syria, an area representative of marginal drylands. We experimentally define an operational classification of household typologies based on their different livelihood strategies, capabilities, and opportunities by applying a Sustainable Livelihoods framework. Livelihoods diversity has implications on where and how research must be targeted to have impact on poverty. Households less endowed in land and natural resources and... |

| This paper presents six key issues from the Rethinking Impact: Understanding the complexity of poverty and change Workshop (RIW) held in Cali, Colombia, March 26–28, 2008. The workshop discussed how agricultural and natural-resources research can be more effective in generating solutions for poverty alleviation and improving gender, social inclusion and equity, and how such research can be brought into the mainstream and how its impact can be assessed. A diverse group of over 60 participants (42% women) from 33 organizations (54% CGIAR and 46% non-CGIAR) attended the meeting. In this paper, we do not purport to represent a consensus of opinion among this diverse group, but rather our perspectives as the meeting organizers. These ‘take home messages’ were... |

| This study investigated the impact of HIV/AIDS on food security and household vulnerability in Swaziland. Personal interviews with 847 selected farming households revealed an increase in sales of crops and livestock to finance funerals and healthcare, a decrease in expenditure on agricultural inputs, and an increase in expenditure on medical bills and funerals. Most households were vulnerable to food insecurity. The affected households therefore need assistance in order to maintain food production and security, including support in the form of agricultural inputs such as fertilisers and seeds through the markets and special arrangements to allow them access to affordable inputs. Therapeutic feeding and home based care will be needed for the chronically ill... |

| This paper uses a cross-sectional approach to analyze the impacts of climate change on animal husbandry and the way farmers adapt. The study is based on surveys of almost 5000 livestock farmers across ten countries in Africa. A traditional Ricardian regression finds that the livestock net revenues of large farms in Africa are more sensitive to temperature than those of small farms. Cross-sectional analysis also reveals that large farms (but not small farms) have fewer animals per farm in warmer places. Farmers tend to select beef cattle and chickens in cool climates and goats and sheep in hot climates. Using the Ricardian results and examining climate scenarios for 2060 and beyond, the net revenues of small farms are predicted to increase as much as 120%... |

| This paper presents a framework for investigating the intersection of collective action and gender; i.e. how gender-oriented analysis can foster more effective collective action in the context of agriculture and natural resource management and how collective action can be used as a vehicle for gender equity. We begin with definitions of the key concepts and then present three entry points for a gendered analysis of collective action-motivations, effectiveness, and impact on gender equity- vis-à-vis the Institutional Analysis and Development (IAD) framework (Oakerson 1992; Ostrom 1991). At the heart of this framework is the action arena, which is shaped by a host of initial conditions, including asset endowments, vulnerabilities, and legal and governance... |

| The paper analyses methodological and practical solutions that have been introduced to assess the impact of the Rural Development Programme 2007-2013 in Latvia. The work on the development of the evaluation of the impact of rural support is only in progress, the range of data sources is not large either. Therefore the author offers a solution how the evaluation of the RDP is organized in Latvia, with the resources and the amount of information available, and what activities are planned in the future. Special attention is devoted to the development of the methodology for calculating the direct economic effect, including the principles of the formation of the group of the affected farms and the control group, as well as the choice of the range of indicators... |

| ABSTRACT This study aimed to evaluate some changes in the metabolism of papaya fruits submitted to damage by impact, abrasion and compression. Injuries were caused in two areas of 15 cm2 each; in diametrically opposite positions in the equatorial region of ‘Improved Sunrise Solo Line 72/12’ papaya fruits in ripening stage 3 (fruits with 25-40% of yellow skin). After damage, fruits were stored at 15 ± 1 °C and 85 ± 5% RH, and samples were taken at intervals of two days to evaluate skin color index, incidence of diseases, loss of fresh weight, leak of solutes, pulp firmness, soluble solids content and pectinmethylesterase and polygalacturonase activities. The respiratory rate was measured at intervals of 4, 8, 12, 24, 48 and 72 hours after damage. The... |

| Many ecosystems of western North America have been dramatically changed by non-native species. Here, we review ecological impacts of 56 plant, animal, fungus, and protist species that were brought to this region by humans. We discuss characteristics of invasive species that can lead to major ecosystem impacts, and explore how invasive species alter many different attributes of ecosystems. Specifically, we include examples of invasive species that affect geomorphology, fire regimes, hydrology, microclimate, atmospheric composition, nutrient cycling, and productivity. Finally, we review the direct consequences of biological invasions for some native species. We summarize examples from this paper in Appendix 1. Our examples illustrate how, as invasive species... |

| ABSTRACT Understanding how fire affects the plant biota of the Cerrado is essential for formulating conservational strategies. We evaluated the effects of fires during different periods of the year on the populational structure of Anacardium humile. The research was carried out in areas of typical cerrado stricto sensu in the territory of the Kalunga, state of Goiás, Brazil. These areas, which comprise the same population, were submitted to the following treatments: unburned (control), burned in May 2016 (early fire - EF), and burned in September 2016 (late fire - LF). In July 2018, we delimited two contiguous transects of 100 x 20 m, subdivided into 10 plots of 20 x 20 m, in each area. Fire stimulated the development of branches from basal regrowth in EF... |
