| According to the U.S. National Environmental Policy Act of 1969 (NEPA), federal action to manipulate habitat for species conservation requires an environmental impact statement, which should integrate natural, physical, economic, and social sciences in planning and decision making. Nonetheless, most impact assessments focus disproportionately on physical or ecological impacts rather than integrating ecological and socioeconomic components. We developed a participatory social-ecological impact assessment (SEIA) that addresses the requirements of NEPA and integrates social and ecological concepts for impact assessments. We cooperated with the Bureau of Land Management in Idaho, USA on a project designed to restore habitat for the Greater Sage-Grouse... |

| The National Agricultural Advisory Services (NAADS) program of Uganda is an innovative public-private extension service delivery approach, with the goal of increasing market oriented agricultural production by empowering farmers to demand and control agricultural advisory services. Although initial evaluations of NAADS have been quite favourable, these evaluations have been primary qualitative in nature. This study quantifies the initial impacts of NAADS in the districts and sub-counties where the program was operating by 2005. It is based on descriptive analyses of results of a survey of 116 farmer groups and 894 farmers in sixteen districts where the program was operating at the time and four districts where NAADS had not yet begun operating to control... |

| Although invasive alien species have been identified as the second greatest threat to biodiversity after habitat loss, characterizing and quantifying their impacts on native species and habitats remains a fundamental problem in conservation biology. Here, I review the techniques that are currently used to assess the impact of invasive alien species on biodiversity, highlighting both their uses in invasive species ecology and their limitations in establishing a causal relationship. Adopting a hypothesis-driven experimental approach to impact assessment, and to eradication efforts through adaptive management, would benefit our ecological understanding of invasive species without delaying critical management action that could reduce the spread of invasive... |

| Resumo - Este trabalho apresenta avaliações de impactos socioambientais da adoção de boas práticas zootécnicas e de gestão na produção de ovinos e caprinos no município de Tauá – CE, entre janeiro/2017 e dezembro/2018. Utilizou-se o sistema Ambitec-Agro, composto por matrizes de ponderação multicritério com 148 indicadores, relativos a 27 critérios de desempenho, agrupados em sete aspectos: Eficiência Tecnológica, Qualidade Ambiental, Respeito ao Consumidor, Emprego, Renda, Saúde e Gestão da Propriedade. As boas práticas objeto da avaliação fundamentam-se nas seguintes tecnologias: (i) Controle integrado de verminose, (ii) controle de linfadenite caseosa, (iii) orçamentação forrageira, (iv) estação de monta e (v) práticas de gestão da propriedade.

| Climate change and increasing climate variability threaten the attainment of the Millennium Development Goals (MDG), and some of the worst effects on human health and agriculture will be in sub-Saharan Africa, particularly in vulnerable regions. The relationships between climate change and the vulnerability of resource-poor croppers and livestock keepers and their resilience to current and future climate variability need to be better understood. This paper describes the generation of information that combines projected climate change in agricultural systems with vulnerability data. The results of the analysis, in terms of vulnerable people particularly at risk for deleterious effects of climate change, are being used for impact assessment, targeting and... |

| Mullen (2004,2005) conducted an impact assessment of two ACIAR funded economics research projects enquiring into domestic grain market reform in China. The benefit cost ratio to ACIAR was estimated to be in the range 5:1 to 33:1. The impact assessment was conducted when grain policy was viewed as being in a period of retrenchment rather than reform and hence the assessment was ex ante in nature. Since then the methodology for estimating nominal rates of assistance in China has been modified and the late 90s is now seen as a period when reform continued despite the professed policy stance. It seems opportune to revisit Mullen’s original impact assessment to assess the extent of welfare gains actually achieved. |

| Marker-assisted breeding could have a major impact in relieving productivity constraints that cannot as easily or rapidly be relieved by conventional breeding alone. This paper estimates the benefits of using marker-assisted breeding, as compared to conventional breeding alone, in developing cassava varieties resistant to cassava mosaic disease, green mite, whitefly and post-harvest physiological deterioration in Nigeria, Ghana and Uganda. Marker-assisted breeding is estimated to save at least four years in the breeding cycle for varieties resistant to the pests and to result in incremental net benefits over 25 years in the range of $34 to $800 million depending on the country, the particular constraint and various assumptions. Benefits may reach as high... |

| Biofortification, or the genetic improvement of the nutritional quality of food crops, is a promising strategy to combat undernutrition, particularly among the rural poor in developing countries. However, traditional methods of impact assessment do not apply to biofortified crops as little or no yield increases are expected. Significant progress has been made to develop maize varieties with improved protein quality, collectively known as quality protein maize (QPM). Evidence for the impact of QPM at the community level, as demonstrated by randomized, controlled studies, was evaluated using meta-analysis. A new and generalizable effect size was proposed to quantify the impact of QPM on a key outcome, child growth. The results indicated that consumption of... |
