This study investigated the effects of Covid-19 pandemic on poultry production in South East, Nigeria. Multistage and purposive sampling techniques were used to select a total 150 respondents for study. The instruments data collection was questionnaire interview guide or schedule Focus Group Discussion (FGD) In-depth Interview (IDI) actors sub-sectors also used. Qualitative method analysis. Dat...
Analyzing agro-climatic conditions for the period of 1981–2020 has revealed a tendency local climate warming under condition its aridization in territory Central region Russian Non-Chernozem zone, and new northern borders soybean growing have been marked. The isotherm sum active temperatures established to shifted towards high latitudes by 150–200 km. values increased from 1700–2200 °C 1950–240...
We describe the concept, strategy, and initial results of the Millennium Villages Project and implications regarding sustainability and scalability. Our underlying hypothesis is that the interacting crises of agriculture, health, and infrastructure in rural Africa can be overcome through targeted public-sector investments to raise rural productivity and, thereby, to increased private-sector sav...
The aim of this study is to evaluate the effectiveness of the ‘lure and kill’ technique, commonly called Mass Trapping (MT), compared with the larvicidal technique in olive fruit fly control. Data from different agro-ecological and management conditions were collected in several mass trapping areas in the regions of Tuscany and Liguria during 1999, 2000 and 2001. Data were organized and stored ...
Consensus is growing that agriculture is vulnerable to climate change and adaptation responses are necessary to minimize impacts. Nonetheless, the diversity of potential impacts, agro-ecological contexts and regional capacity for change make understanding adaptation behaviors challenging and ensure that climate change adaptation will not be the same across all contexts. Considering this heterog...
Anthropogenic impacts increasingly drive ecological and evolutionary processes at many spatio-temporal scales, demanding greater capacity to predict and manage their consequences. This is particularly true for agro-ecosystems, which not only comprise a significant proportion of land use, but which also involve conflicting imperatives to expand or intensify production while simultaneously reduci...
This paper reviews an analysis of land use change impacts of expanded biofuel production with GTAP-BIO computable general equilibrium (CGE) model. It describes the treatment of energy substitution, the role of biofuel by-products, specification of bilateral trade, the determination of land cover changes in response to increased biofuel feedstock production, and changes in crop yields – both at ...
The agro-biodiversity present in agro-ecosystems is fundamental guaranteeing sustainability and resilience. However, there are very few approaches for evaluating it and, even less, ones that include indicators to analyze the influence of structural spatial configuration a landscape order favor connectivity productive systems. There also no proposals management conservation practices, producer (...
