CAEL, the Council for Adult and Experiential Learning, works on many levels – from policy at the national, regional and state levels, to on-the-ground initiatives – to provide the tools for adults to successfully enter and advance in the workforce. This session will provide a brief snapshot of some of the tools and projects that have been successful in linking learning to work for high school students and young adults. • Industry-wide online education in the telecommunications and energy industries • A high school pipeline into the energy industry • Career mapping • Stackable credentials linked to sequential education • A nation-wide career readiness credential While this may look like a scattered list, this session will focus on the critical success factors, including the role of technology, common across these initiatives.

This case study highlights the way that women working in peri-urban agriculture in India have to adapt to changing circumstances in order to sustain themselves and their families. It was produced by Siddharth Agarwal, Kanupriya Kothiwal, Shabnam Verma and Sampurna Kundu of the Urban Health Resource Centre, India. Conclusions include agricultural work being one of the major forms of livelihood for peri-urban workers. Many peri-urban workers chose this form of work because they already had the skills from their native rural farms. Women find agricultural work convenient because of its self-paced nature and because farms are mostly close to where they live. Food security is another benefit, as many women are able to procure vegetables and food grains from their farming work. Peri-urban women workers are resilient, adapting to an ever-changing peri-urban ecosystem and often pursuing an additional livelihood in seasons when agricultural work is not available. Their strategy of forming links with more than one employer offering different forms of work is key to this resilience. They are also preparing themselves for a future when farms will be sold to developers and builders, and express anxiety about the uncertainty of sustaining agriculture work in the future. The adaptability and resilience shown by the workers can be tailored to other situations and promoted among vulnerable urban women workers.

Many women in Indore work as informal home-based garment workers. This case study demonstrates their commitment to investing in equipment and learning new skills in order to contribute to the family income. Behind closed doors lies a vast segment of largely invisible women and girls working in India’s flourishing garment industry. Women working from home account for about 14% of urban employment in India. In low- and middle-income countries, outsourced garment production thrives on account of cheap labour to keep the levels of production high and costs low. Through pursuing sewing, women can overcome the limitations of little or no education or formal training. Most women stitchers enhance their skills through experience. This helps them get regular and progressively higher paying piece-rate work. More information: https://www.iied.org/stitching-determination-stories-women-garment-workers-indore-india

Because adaption is not just about addressing vulnerability to climate-related disasters but is also about reducing the economic, social and political vulnerabilities that exacerbate the former, Friendship has developed an integrated and holistic approach that allows transition of vulnerable communities from emergency aid dependence or disaster relief to their development and resilience. This presentation was submitted by Stéphane Van Haute, of Friendship, and features as part of the Marketplace area of the 15th International Conference on Community-based Adaptation (CBA15). The event takes place online from 14-18 June, 2021. More details: https://cba15.iied.org/

This presentation was made by Pauline Zei at a webinar on Wednesday, 2 June that discussed the challenges around, and opportunities for, producer voice and agency in the design and implementation of the new Living Income Differential (LID) in Ghana and the Côte d'Ivoire. The online event on 'Cocoa producer agency and the living income differential: lessons from civil society organisations' was organised by the International Institute for Environment and Development (IIED). Zei is director of Inades-Formation Cote d'Ivoire. She holds a degree in agronomy from the Institut National Polytechnique Félix Houphouët Boigny in Yamoussoukro, specialising in crop protection. Inades-Formation is a network of pan-African associations that works for equitable and sustainable development in Africa. This was the seventh in a series of events organised under the IIED-led Empowering Producers in Commercial Agriculture (EPIC) project. EPIC is funded by the UK Foreign, Commonwealth & Development Office through its Commercial Agriculture for Smallholders and Agribusiness (CASA) programme, though the views expressed do not necessarily reflect the views of the UK government. CASA seeks to increase economic opportunities for smallholders by demonstrating the commercial viability of businesses with significant smallholder supply chains and attracting more investment into the sector.

This is a presentation from the final event of an online learning series for the East African Community region on communities combating illegal wildlife trade. The event discussed the future of the ‘Local communities: First Line of Defence against Illegal Wildlife Trade (FLoD)’ methodology, which aims to support designers and implementers of anti-poaching and anti-wildlife trafficking strategies and projects to effectively engage local communities as partners. The events are organised by IUCN, together with the International Institute for Environment and Development and IUCN CEESP/SSC Sustainable Use and Livelihoods Specialist Group. They are supported by USAID Kenya and East Africa through the Conserving Natural Capital and Enhancing Collaborative Management of Transboundary Resources (CONNECT) project, and will supplement the comprehensive training course on FLoD, which is currently under development with support from the BIOPAMA programme, supported by the European Union and the Organisation of African, Caribbean and Pacific States.

This is a presentation by Duncan MacQueen, principal researcher at the International Institute for Environment and Development (IIED), about the importance of including smallholder producers and producer organisations in sustainable value chains to strengthen local resilience to external shocks. Macqueen used the example of his work with the Forest and Farm Facility (FFF) program at the FTA Science Conference 2020. The presentation focuses on the role of commercial organisation around accountable finance systems at four tiered levels: local producer groups, regional aggregators and processors, national advocacy federations, international alliances.
