Fatigue vulnerability analysis of a historical railway steel bridge

Damage accumulation deriving from load cycles is one of the most important features in the fatigue vulnerability assessment of historical steel bridge structures. Starting from Wohler curves and referring to Eurocodes (Eurocode 3, 1993) and some current normatives (Italian Ministry of Infrastructure, 2008) a vulnerability analysis has been performed for estimating the structure probability to be damaged over time. Steel strength and corrosion depth probabilistic distributions have been discretized in finite intervals, combining them in order to represent all the possible bridge conditions. The performance levels considered in the analyses have been defined as submultiples of the maximum steel strength value for different specific number of cycles that will cause fatigue failure, assessing the produced damage. The adopted procedure has allowed to identify a combined fatigue-corrosion failure probability for each specific train-load and relative number of cycles considered, configuring it as a valuable tool for the assessment, prevention and management of the existing historical steel bridges

Children, Youth & Women Organizations in Agriculture Climate Action & Sustainability

Guest speakers: Keithlin Caroo, Executive Director at Helen's Daughters, Helen's Daughter - St. Lucia, Mr. Alpha Sennon, Founder of WHYFARM, WhyFarm - Trinidad & TobagoMr. Keithlin Caroo, Executive Director at Helen's Daughters and IICA Goodwill Ambassador for Sustainable Development, shares the experiences of Helen's Daughters, which is a non-profit organisation based in St. Lucia and is now expanding to other islands of the Caribbean including St. Kitts & Nevis, focuses on the economic development of rural women through improved market access, adaptive agricultural techniques, and capacity-building. Helen's Daughters work at a grassroots level providing training, mentorship, micro-investment, access to high-value markets and a structured care-system for rural women farmers, who have largely been unacknowledged and under-supported in the agricultural sector. They also use advocacy to address gender inequalities by seeking opportunities for female farmers, and to put food security and climate resilience in the public and policy agenda. Helen's Daughters advocacy involves leveraging media opportunities and our partnerships with the public and private sectors to position rural women as key actors in driving sustainable development in the Caribbean. Ms. Caroo speaks on the program that Helen's Daughters offer to help empower women in agriculture which includes, the Agri-Apprenticeship Programme, FarmHers Market, Rural Women’s Ag-cademy & Women’s Farmers Academy among others.Mr. Alpha Sennon, Founder of WHYFARM shares the experiences of WHYFARM (We Help You-th Farm), an NGO in Trinidad and Tobago that pioneers Agricultural Educational Entertainment (Agri-Edutaintment) with a mission to promote the importance of sustainable agriculture among youth and children, build their capacity in Agricultural Entrepreneurship, and empower them to contribute to achieving global food and nutrition security by the year 2050. WHYFARM has developed AGRIMAN and PhotosyntheSista, the 1st Food and Nutrition Security Superheroes, that inspires future feeders. Mr. Sennon on strategies for getting childrend and youth more engaged in agriCOOLture, and delves into some of the agricultural educational entertainment that WHYFARM develops including comic and activity books for youth and children which is equally enjoyed by adults, motion comics, Farm visits and Agriman School tours among others

Caribbean Specific Agriculture App to Help Farmers Adapt to Climate Change

Guest speakers: Mr. Richard Rampersaud, Agribusiness Specialist, Inter-American Institute for Cooperation on Agriculture (IICA) - Trinidad & Tobago, Ms. Laura MacNeil, Founder of CaribFarm, CaribFarm - CanadaMr. Richard Rampersaud, Agribusiness Specialist at IICA Delegation in Trinidad & Tobago presents the FARMVUE App which digitally record and easily monitor all aspects of a farm. Mr. Rampersaud explains the reason why the app was developed for Caribbean farmers, its vlaue and benefits to farmers, some of the key features of the app as well as the future plans for the app.Ms. Laura MacNeil, Founder of CaribFarm presents the FarmerCommunity App which seeks to provide free and readily accessible information that will support positive and measurable impact in the lives of small-scale farmers throughout the Caribbean. This app is geared towards providing farmers access to sustainable farming methods directly from agriculture experts and other farmer
