Evidence of collaborative opportunities to ensure long-term sustainability in African farming
Farmers face the challenge of increasing production to feed a growing population and support livelihoods, whilst
also improving the sustainability and resilience of cropping systems. Understanding the key factors that influence
farming management practices is crucial for determining farmersâ adaptive capacity and willingness to engage in
cooperative strategies. To that end, we investigated management practices that farmers adopt and the factors
underlying farmersâ decision-making. We also aimed to identify the constraints that impede the adoption of
strategies perceived to increase farming resilience and to explore how the acceleration of technology adoption
through cooperation could ensure the long-term sustainability of farming. Surveys were distributed to farming
stakeholders and professionals who worked across the contrasting environments of Morocco. We used descriptive
statistics and analysis by log-linear modelling to predict the importance of factors influencing farmersâ decision-
making. The results show that influencing factors tended to cluster around environmental pressures, crop
characteristics and water availability with social drivers playing a lesser role. Subsidies were also found to be an
important factor in decision-making. Farming stakeholders generally believed that collaborative networks are
likely to facilitate the adoption of sustainable agricultural practices. We conclude that farmers need both eco-
nomic incentives and technical support to enhance their adaptive capacity as this can lessen the socioeconomic
vulnerability inherent in arid and semi-arid regions
Excitonic luminescence of the I-intercalated HfS
Photoluminescence from bulk HfS grown by the chemical vapor transport
(CVT) method is reported. A series of emission lines is apparent at low
temperature in the energy range of 1.4 - 1.5 eV. Two groups of the observed
excitonic transitions followed by their replicas involving acoustic and optical
phonons are distinguished using classical intensity correlation analysis. The
emission is attributed to the recombination of excitons bound to iodine (I)
molecules intercalated between layers of HfS. The I molecules are
introduced to the crystal during the growth as halogen transport agents in the
CVT growth process. Their presence in the crystal is confirmed by secondary ion
mass spectroscopy.Comment: 5 pages, 6 figure
Field trials of plum clones transformed with the Plum pox virus coat protein (PPV-CP) gene
Transgenic clones C2, C3, C4, C5, C6, and PT-6, of plum (Prunus domestica L.) transformed with the coat protein (CP) gene of Plum pox virus (PPV), PT-23 transformed with marker genes only, and nontransgenic B70146 were evaluated for sharka resistance under high infection pressure in field trials in Poland and Spain. These sites differed in climatic conditions and virus isolates. Transgenic clone C5 showed high resistance to PPV at both sites. None of the C5 trees became naturally infected by aphids during seven (Spain) or eight (Poland) years of the test, although up to 100% of other plum trees (transgenic clones and nontransgenic control plants) grown in the same conditions showed disease symptoms and tested positively for PPV. Although highly resistant, C5 trees could be infected artificially by chip budding or via susceptible rootstock. Infected C5 trees showed only a few mild symptoms on single, isolated shoots, even up to 8 years post inoculation. These results clearly indicate the long-term nature and high level of resistance to PPV obtained through genetically engineered resistance
Digital Soil Mapping in the Irish Soil Information System
Harmonised soil data across Europe with a 1:250 000 geo-referenced soil database will allow for exchange of data across member states and the provide the information needed by the European Commission and European Environment Agency for reporting on issues relating to soil quality under a fu-ture Soil Framework Directive. Within this context, the Environmental Protection Agency of the Republic of Ireland commissioned a project run by Teagasc to produce a 1:250 000 soil map of the Republic of Ire-land. Delivery of this map and associated database is a collaborative effort between Teagasc, the National Soil Resources Institute at Cranfield in the UK and University College Dublin.Environmental Protection Agenc
Clinical Outcomes of Extracranial Carotid Artery-Related Stroke Eligible for Mechanical Reperfusion on Top of Per-Guidelines Thrombolytic Therapy:Analysis from a 6-Month Consecutive Patient Sample in 2 Centers
BACKGROUND: Systemic intravenous thrombolysis and mechanical thrombectomy (MT) are guideline-recommended reperfusion therapies in large-vessel-occlusion ischemic stroke. However, for acute ischemic stroke of extracranial carotid artery origin (AIS-CA) there have been no specific trials, resulting in a data gap. MATERIAL/METHODS: We evaluated referral/treatment pathways, serial imaging, and neurologic 90-day outcomes in consecutive patients, presenting in a real-life series in 2 stroke centers over a period of 6 months, with AIS-CA eligible for emergency mechanical reperfusion (EMR) on top of thrombolysis as per guideline criteria. RESULTS: Of 30 EMR-eligible patients (33.3% in-window for thrombolysis and thrombolysed, 73.3% male, age 39-87 years, median Alberta Stroke Program Early Computed Tomography Score (ASPECTS) 10, pre-stroke mRS 0â1 in all, tandem lesions 26.7%), 20 (66.7%) were EMR-referred (60% â endovascular, 6.7% â surgery referrals). Only 40% received EMR, nearly exclusively in stroke centers with carotid artery stenting (CAS) expertise (100% eligible patient acceptance rate, 100% treatment delivery involving CAS±MT with culprit lesion sequestration using micronet-covered stents). The emergency surgery rate was 0%. Baseline clinical and imaging characteristics did not differ between EMR-treated and EMR-untreated patients. Ninety-day neurologic status was profoundly better in EMR-treated patients: mRS 0â2 (91.7% vs 0%; P<0.001); mRS 3â5 (8.3% vs 88.9%; P<0.001), mRS 6 (0% vs 11.1%; P<0.001). CONCLUSIONS: In a real-life AIS-CA setting, the referral rate of EMR-eligible patients for EMR was low, and the treatment rate was even lower. AIS-CA revascularization was delivered predominantly in stroke thrombectomy-capable cardioangiology centers, resulting in overwhelmingly superior patient outcome. Large vessel occlusion stroke referral and management pathways should involve centers with proximal-protected CAS expertise. AIS-CA, irrespective of any thrombolysis administration, is a hyperacute cerebral emergency and EMR-eligible patients should be immediately referred for mechanical reperfusion
Mapping Soils in Ireland
peer-reviewedThis project is jointly funded by Teagasc and EPA STRIVE funding.Harmonised soil data across Europe with a 1:250 000 geo-referenced soil database will allow for exchange of data across member states and the provide the information needed for reporting on issues re-lating to soil quality under a future Soil Framework Directive. The current status of soils data available in Eu-rope is inconsistent at best. The Irish Soil Information System (ISIS) project is currently developing a national soil map of 1:250,000 and an associated digital soil information system, providing both spatial and quantita-tive information on soil types and properties across Ireland. Both the map and the information system will be freely available to the public through a designated website.This project is jointly funded by Teagasc and EPA STRIVE funding
