Building with Lime Stabilized Soil

How best can we stimulate lasting recovery from floods, earthquakes, and other climate disasters, with limited resources and funds? How can we deliver housing and adequate shelter that will protect as many people as possible across the world from anticipated future floods or extreme weather? Widely available limestone is a key component to achieving these goals. When burned and combined with local clay-rich soil or pozzolans (locally available burnt brick dust or various types of ash) it can create low-cost, flood-resilient building components: foundations, wall blocks, renders, plasters, and floor and roof screeds that remain stable in wet conditions and under water. Many communities are familiar with basic construction, and so, once equipped with the skills to work with these low-cost, locally available materials, they can lead their own recovery. Advice includes the selection, preparation and application of binders, aggregates and pozzolans and their mix ratios supported by detailed illustrations of practical field tests for a range of building elements. As well as setting out methods for using soil and other local materials in the construction of new housing in rural communities affected by climate disaster, Building with Lime-Stabilized Soil also describes their use in repairs to historic buildings. Many old buildings, some standing for over 700 years, are testament to the durability of these materials. Stafford Holmes and Bee Rowan show with numerous detailed examples and instruction that the use of lime-stabilised soil is the most ecological, cost-saving, appropriate technology for a wide range of buildings across the world. Bee Rowan is Director of Strawbuild, one of the United Kingdom and Europe’s foremost training companies in sustainable building techniques, which specializes in the use and promotion of natural, local and low embodied energy materials including lime and clay. Stafford Holmes is an architect who specializes in the care and repair of historic buildings. He first carried out research and development of stabilized soils in West Africa in 1980, and has written books and technical articles on building limes, describing their many uses and ecological benefits. These include Building with Lime, with Michael Wingate, first published in 1997. Both authors are visiting lecturers with various higher educational institutes and promote the use of natural materials for construction through educational programmes, lectures and demonstrations.

Attributing Development Impact: The qualitative impact protocol case book

Substantiating cause and effect is one of the great conundrums for those aiming to have a social impact, be they an NGO, SII fund, or multinational corporation. All face the same quandary: how do you know whether or how you contributed to an observed social change? The Qualitative Impact Protocol (QuIP) was researched and developed at the Centre for Development Studies in an effort to tackle this attribution challenge. Attributing Development Impact: The Qualitative Impact Protocol Case Book sets out case studies across seven countries (Ethiopia, India, Malawi, Mexico, Tanzania, Uganda and UK) where the QuIP has been used by a range of organisations involved in development - private sector, public sector, and civil society to elucidate their role in social change. 
 This book shares the real-life experiences of organisations in the field tackling the attribution problem , exploring the measures they took to overcome various challenges, and illuminating the results they could not have obtained otherwise. QuIP is at the heart of this story, and this book will help practitioners determine when and how to use it effectively.

Taking Shelter: Housing Finance for the World’s Poor

PUBLISHING NOVEMBER 2020How do low-income families, representing some 70% of the world's population, finance home building and improvements - and how is the financial sector, from microfinance institutions and banks to investors and regulators, changing to serve their needs?The practice of housing microfinance has evolved substantially, with a large number of innovations across the entire housing financing ecosystem. New research methodologies, such as financial diaries, have yielded a deeper and more nuanced understanding of how poor households use finance, both formal and informal, to construct their homes. The housing finance industry is also growing. The home improvement loans that are at the heart of housing microfinance are offered in hundreds of institutions, leading to important lessons on how they work. Meanwhile, a new class of institutions - micro-mortgage lenders - have emerged to fill the space between housing microfinance and traditional mortgage lending. On the funding side, debt funding is now available to finance or re-finance housing microfinance loans; while other investors have carved out a new role for equity investing in housing finance - showing the critical role that private investors can play. And now a new breed of public wholesale financing has emerged, showing the catalytic role public sector investment can play in encouraging housing finance markets in their countries. This volume explores recent innovations in housing microfinance, presented by the innovators themselves: a range of leading experts in the field, from field researchers and financial providers, to investors and regulators. It is a key reference to any reader interested in expanding housing finance for the world's poor.
