Development of a forecast-based action mechanism addressing drought-induced food insecurity in Madagascar

Welthungerhilfe has developed and implements a forecast-based action mechanism addressing drought-induced food insecurity in several regions of Madagascar. The mechanism is based on regionally specific pre-financed Early Action Protocols (EAPs), triggered by a water requirement satisfaction index-based agricultural drought model.

The project’s goal is to develop a number of EAPs addressing food insecurity in several regions of Madagascar. The developed, localized EAPs are based on impact-based forecasting methods and sufficiently support coping strategies against drought. The EAPs will be pre-financed and connected to a risk-based scientific trigger model.

Anticipation in practice: project description

FbA programme at Welthungerhilfe

Since 2017, Welthungerhilfe has developed and implemented a forecast-based action mechanism in Madagascar. In cooperation with the Start Network and several NGOs, trigger-based EAPs have been developed. The objective of the FbA programme under Welthungerhilfe is to scale up the forecast-based action approach for drought-induced food security in Kenya and Zimbabwe. More details on these projects can be found under the respective Anticipation Hub project pages.

Reduce the risk of drought-induced food insecurity

The early action mechanism reduces the impact of a predicted drought on food security for the most vulnerable communities. Based on in-depth analyses, several local EAPs have been, and will be, developed and connected to a trigger-based financing mechanism. The drought model that triggers the EAPs is based on the water requirement satisfaction index (WRSI), an index for crop monitoring and drought-related water stress, and on local rainfall data, and is informed by comprehensive risk and vulnerability data. On the basis of historical analyses, the model addresses drought events with an average return period of 10 years.

In cooperation with the Start Network and other NGOs, several localized EAPs are being developed using impact-based forecasting models and addressing specific coping strategies, in order to minimize the drought-induced damages and losses of affected households. The EAPs include the roles and responsibilities of all involved stakeholders, as well as particular early actions which are specifically tailored to the regional context, timing and severity of drought. The EAPs are designed to be rolled out immediately after the drought forecasting model has been triggered.

The project uses the results of conducted household economy analysis (HEA) vulnerability analyses to identify further suitable areas to be covered by EAPs. As soon as the drought model is triggered, a range of early actions, such as early cash, in-kind assistance and awareness-raising activities, will be activated, depending on the timing of the trigger and the threshold reached.

Forecast-based action in an NGO environment

Our vision is to strengthen forecast-based action and anticipatory humanitarian initiatives among NGOs. Therefore, and to ensure long-term sustainability, the ownership of local EAPs should be shared with other stakeholders. With this objective in mind, Welthungerhilfe has partnered with the Start Network, which consists of more than 50 NGO members. Start Network member organizations in Madagascar, and in the other two programme countries (Kenya and Zimbabwe) can become so-called  'EAP custodians' and, as such, will collaborate in the development and implementation of EAPs. Such a formalized cooperation ensures local institutionalization, communal involvement, as well as high accountability towards local stakeholders and beneficiaries. The guidance and facilitation of this process will be done by Welthungerhilfe.

The forecast-based action mechanism will be developed, specifically adapted and set up within an international and national NGO environment. To ensure effective implementation, the system is being developed in cooperation with the Start Network, Start Network member organizations, universities, local partners, national government institutions, local authorities and target group communities.
The Start Network will play a pivotal role as technical advisor, but also by providing the financing mechanism supporting the forecast-based action system. It will provide continuous technical guidance on the model development, and quality assurance on the EAPs developed by Welthungerhilfe and other Start Network member organizations in-country. When triggers are met, the Start Network will fund the EAP implementation. Provision of the necessary funding to support these EAPs is one of the reasons behind the Start Network’s quality assurance role in their development. This funding support is part of a wider NGO-specific financing facility (in preparation), which will enable donor money to be deployed at scale in timely, predictable and efficient ways to frontline NGOs such as Welthungerhilfe.

Lessons learnt

  • Scheduling longer lead-in time (especially in new countries of implementation) to ensure proper introduction to concepts, capacity building and training, as well as the ‘buy-in’ of various stakeholders

  • Scheduling more time for coordination, scoping and understanding the specific local contextahead of programme initiation

  • Fostering of constructive exchange and coordination between Welthungerhilfe internally but also with other stakeholders (such as Start Network and members, national government institutions and local authorities, but also between different initiatives, such as the Welthungerhilfe FbA Programme and Start Network Pakistan DRF initiative)

  • Scheduling sufficient time in order to build a robust scientific model (or even consider to outsource)

In the drought-prone regions of Madagascar, people are constantly in need of humanitarian aid. Aid for food and food crises is now provided on the basis of indicators that allow us to react to a growing crisis situation. This approach is an important added value in the new drought-response strategy under the 2020-2023 contingency plan. In fact, it enables early multisectoral planning, which is a first for Madagascar in this way.

Welthungerhilfe’s FbA project in Madagascar offers the opportunity to take advantage of synergies with other FbA stakeholders and to develop a cross-pillar (IFRC, UN, NGO) mechanism coordinated between organisations. This constellation opens up the potential for EAPs and early interventions to be coordinated.

Welthungerhilfe’s FbA mechanism in Madagascar covers agricultural drought by using advanced satellite-based rainfall data sets, crop and planting calendar data together with soil data sets to generate the Water Requirement Satisfaction Index (WRSI), an index for crop monitoring and drought related water stress. The WRSI will then be combined with the exposure (yield reduction function) and the social vulnerability to estimate the impact of the agricultural drought.
