  • The number of rigorous studies on WASH promotion in households, schools and communities has increased substantially.

  • Very few rigorous studies exist on WASH promotion in medical facilities.

  • Many new studies evaluate previously under-researched approaches, such as community-led total sanitation, and measure important sector outcomes, including school attendance and reducing open defecation.

World Humanitarian Day 2018

Over 200 million people are in urgent need of humanitarian assistance across the world today. In 2017, the UN-coordinated appeals reported a shortfall of 41 per cent, despite receiving a record amount of funding. As the demands on these limited funds increase, there is a concurrent increase in the need for high-quality evidence on the most effective ways to improve humanitarian programming.

Decades of research shows that risks in agricultural production trap farmers in a vicious cycle of low investment, low productivity and poverty. Agricultural risk mitigation programmes can play an important role in breaking this poverty trap. Many governments, multilateral development organisations and private agencies are proposing, piloting and implementing at scale programmes that use tools for financial agricultural risk mitigation (FARM). The potential of FARM instruments (e.g.

The improvement of agricultural innovations and technologies in low- and middle-income countries is paramount to increasing agricultural production and income sustainability. Although many agricultural technologies are available, adoption remains low among smallholder farmers. In order to identify existing evidence about the effectiveness of agricultural innovation programmes, 3ie produced an evidence gap map (EGM) of relevant completed and ongoing impact evaluations and systematic reviews.

In low- and middle-income countries, sanitation and hygiene promotion programmes aim to promote sanitation and improved hygiene as a means of preventing infectious diseases such as diarrhoea and cholera and to achieve community empowerment and human rights. Achieving sustained and equitable sanitation behaviour change is a major policy objective, and many scientific studies claim to measure improvements in these outcomes and identify how to make programmes more effective. This summary report is based on the first systematic review of that evidence.

Although HIV testing, care and treatment coverage have been improving in Sub-Saharan Africa (UNAIDS) 2012), significant numbers of HIV-positive individuals still drop out of HIV care at various stages along the care continuum. One approach to improving HIV and AIDS services along this continuum is to integrate them with other health services.

This brief is based on a forthcoming systematic review on Short-term WASH interventions in emergency response: a systematic review, by Yates et al. The review synthesised findings from 106 published and grey literature papers that evaluated 114 WSAH interventions across 39 low- and middleincome countries. The current state of evidence shows that most of the available evidence addresses the question of whether or not these interventions works, but little addresses long-term effectiveness or if the intervention had the intended impacts or not.

This systematic review assesses the extent to which WASH policies, programmes and projects in eleven priority countries have been inclusive of different population segments during the Millennium Development Goals (MDG) period. It examines whether life cycle segments (LCS), such as sex, age, gender and disability, and geographic and social segments (GSS), such as urban or rural location or socioeconomic status have been reflected in WASH policies, programmes and projects. The authors find they have increasingly identified LCS and GSS population segments.

3ie’s Humanitarian Assistance Thematic Window (HATW) aims to produce high-quality evidence to help inform policy and programming in the humanitarian sector. 3ie is supporting impact evaluations and synthesising evidence to understand what is effective and efficient in delivering programmes in fragile and conflict-affected contexts, including what can help to improve recovery and build resilience. We are funding studies that use innovative approaches, are gender responsive and equity focused, and adhere to the ethical standards in evaluation research with vulnerable populations.

Humanitarian actors have a responsibility to ensure that assistance is provided in a way that minimizes risks and maximizes benefits to people affected by crisis. However, there are many challenges in evaluating ‘what works’ in addressing the needs of crisis-affected populations, and translating research evidence into practice in complex environments with limited resources.
