Brief: Future climate projections for Malawi

UMFULA

This brief provides an overview of future climate change in Malawi, using results from the latest available climate model simulations. The UMFULA research team analysed 34 Global Climate Models (GCMs) that provide projections for Malawi to help planning and decision…

Climate Risk and Vulnerability Handbook for Southern Africa

Claire L Davis-Reddy and Katharine Vincent

CSIR and Kulima have launched the second edition of the Climate Risk and Vulnerability Handbook for Southern Africa. This handbook was conceived and designed with the intent to provide decision-makers with up-to-date information, appropriate for country planning, on the impacts…

Guide: How to understand and interpret global climate model results

Declan Conway, Katharine Vincent, Sam Grainger, Emma Archer van Garderen & Joanna Pardoe

Global climate models (GCMs) are the most widely used method to understand future climate change. A new guide from the Future Climate for Africa Programme explains how to interpret GCM results, in order to understand what models tell us about…

Brief; Future Climate Projections for Tanzania

Declan Conway, Neha Mittal, Emma Archer, Joanna Pardoe, Martin Todd, Katharine Vincent and Richard Washington

The UMFULA research team analysed 34 Global Climate Models that provide projections for Tanzania to try to distil robust messages and some key trends that may help planning and decision making. The Country Climate Brief provides an overview of future…

Current warming will reduce yields unless maize breeding and seed systems adapt immediately

A. J. Challinor, A.-K. Koehler , J. Ramirez-Villegas, S. Whitfield and B. Das

The development of crop varieties that are better suited to new climatic conditions is vital for future food production. Increases in mean temperature accelerate crop development, resulting in shorter crop durations and reduced time to accumulate biomass and yield. The…

Large differences in regional precipitation change between a first and second 2 K of global warming

Peter Good , Ben B.B. Booth , Robin Chadwick , Ed Hawkins, Alexandra Jonko & Jason A. Lowe

For adaptation and mitigation planning, stakeholders need reliable information about regional precipitation changes under different emissions scenarios and for different time periods. A significant amount of current planning effort assumes that each K of global warming produces roughly the same…

The onset and cessation of seasonal rainfall over Africa

Caroline M. Dunning, Emily C. L. Black, Richard P. Allan

Variation in the seasonal cycle of African rainfall is of key importance for agriculture. Here an objective method of determining the timing of onset and cessation is, for the first time, extended to the whole of Africa. The method is…

Urban groundwater quality in sub-Saharan Africa: current status and implications for water security and public health

D. J. Lapworth, D. C. W. Nkhuwa, J. Okotto-Okotto, S. Pedley, M. E. Stuart, M. N. Tijani & J. Wright

Groundwater resources are important sources of drinking water in Africa, and they are hugely important in sustaining urban livelihoods and supporting a diverse range of commercial and agricultural activities. Groundwater has an important role in improving health in sub-Saharan Africa…

The Use of Remotely Sensed Rainfall for Managing Drought Risk: A Case Study of Weather Index Insurance in Zambia

Emily Black, Elena Tarnavsky, Ross Maidment , Helen Greatrex , Agrotosh Mookerjee, Tristan Quaife and Matthew Brown

Remotely sensed rainfall is increasingly being used to manage climate-related risk in gauge sparse regions. Applications based on such data must make maximal use of the skill of the methodology in order to avoid doing harm by providing misleading information.…

Recent observed and simulated changes in precipitation over Africa

Ross I. Maidment, Richard P. Allan, and Emily Black

Multiple observational data sets and atmosphere-only simulations from the Coupled ModelIntercomparison Project Phase 5 are analysed to characterise recent rainfall variability and trends overAfrica focusing on 1983–2010. Data sets exhibiting spurious variability, linked in part to a reduction in raingauge…
