Adaptive Introgression: An Untapped Evolutionary Mechanism for Crop Adaptation
A new paper
reviews studies of adaptive introgression in crop species, presenting methodological approaches and challenges to detecting it. Looking particularly at the potential for this evolutionary mechanism for the adaptation of crops, this study argues that screening the wild introgression already existing in the cultivated gene pool may be an effective strategy for uncovering wild diversity relevant for crop adaptation to current environmental changes and for informing new breeding directions.

Flooding forecasting gives Africa's first pre-emptive disaster response support
Cyclone Idai provided international disaster risk advisers and humanitarian aid organisations a rare opportunity to test a flood forecasting method that allowed response teams to pre-empt which areas would be worst hit by flooding and deploy relief operations ahead of the arrival of Cyclone Kenneth, which made landfall less than a month after the devastation of Cyclone Idai.

OPINION: Devastating floods over Malawi - An experience to learn from
The following blog
written by UMFULA
researcher Dorothy Tembo-Nhlema provides insights on the floods that devastated Malawi earlier this year, and the lessons that should be embraced by policy makers in the future.
Lusaka's water security needs integrated planning and governance
Lusaka is one of Africa’s fastest growing cities, and urban densification and economic growth will call for more strategic planning of its water supply and infrastructure. The Zambian capital has enough water supply for the foreseeable future, however the growing demand for this resource from city users, the hydro-power scheme on the river which supplies Lusaka’s electricity, and the sugarcane industry upriver of the city, will call for greater cooperation between the city and various government departments that are responsible for these different sectors.

Finding unlikely connections: when soil meets sky in atmospheric science
Dr Conni Klein, an atmospheric scientist from the Centre for Ecology and Hydrology
, connected with her AMMA 2050 colleague Dr Bamba Adama, a meteorologist and climate scientist at the Université Félix Houphouët Boigny
in Abidjan, to understand how soil type affects cloud formation and changes in monsoon rainfall patterns in West Africa. Read the blog here
'Hamster wheel' of short term planning hampers Malawi's climate response
In this blog
, Dr Katharine Vincent, researcher in the UMFULA project, argues that Malawi is caught in a pattern of short-term planning and response, when it comes to flooding events like Cyclone Idai. Vincent and colleagues are hoping to address the short-term nature of disaster response by supporting the Malawian government in using five to 40 year climate information in medium-term planning.
Digital dashboard brings early-warning tool for disease outbreaks in Maputo
When the Mozambican capital of Maputo gets hit by heavy storms, some parts of the city experience flash floods, leading to stagnant water and outbreaks of diseases like malaria or cholera. FRACTAL researchers have been instrumental in designing a new digital tool that will help the municipality better anticipate where the disease hotspots will be, and where those are in relation to the best medical treatment centres.

Beira: rebuild or relocate after mega-cyclone Idai?
Professor Genito Maure from the Eduardo Mondlane University
in Maputo, in this blog
, explains that residents of the Mozambican city of Beira may not have had enough agency to respond adequately to storm warnings issued by the state meteorological services ahead of the arrival of Cyclone Idai this month, because they may not have had anything to compare a storm of this magnitude to.
'Big data' to help plan for climate shocks in East Africa
looks into a tool being developed to analyse large data sets in a way that will help the end-users understand how projected climate variability may affect small scale farming communities where rising temperatures and increasingly unpredictable rainfall patterns could threaten families’ livelihoods in future.
How drought or flooding knock small businesses in African cities
By looking at different case studies linked to the 2015/16 El Nino weather event, researchers found that a lack of access to loan facilities and finance is one of the biggest hurdles to small city-based businesses adapting to climate extremes in the region. Read more here.
Creating a two-way dialogue for improved advocacy and communication
As part of the HyCRISTAL project
, farmers in Uganda are being trained to produce video stories that engage communities and farmers in investigating their own contexts, whilst linking them up with the key people in decision-making positions for more targeted advocacy messaging and vertical communication. Read more here
London Climate Action Week, 1-8 July, London, United Kingdom
London Climate Action week
(LCAW), hosted by the Mayor of London and the greater London authority, will mobilise climate expertise and talent from across sectors to run events in the city focused on taking local, national and international action. A number of events will be held during the week to highlight the scaling up of practical solutions and identify new solutions to help cut carbon emissions to keep global temperature increases within 1.5°C and support the Paris Agreement.
Webinar: Can we reduce GHG emissions from livestock? A feasibility and investment study from East Africa, 10 July
Climate Action Summit 2019, 23 September, New York City, US
This CGIAR webinar
will present the context of the livestock sector in East Africa, including climate finance, an overview of the feasibility of ten low emissions development (LED) interventions for the livestock sector in Kenya and Ethiopia, and present an investment study on one of the most promising options. Register here.
African Climate Risks Conference, 7-9 October, Addis Ababa, Ethiopia
The UN 2019 Climate Summit
will seek to challenge states, regions, cities, companies, investors and citizens to step up action in six areas: energy transition, climate finance and carbon pricing, industry transition, nature-based solutions, cities and local action, and resilience.
The African Climate Risks Conference
overarching theme is “Dismantling barriers to urgent climate change adaptation actions
” and is an open platform for sharing the latest climate research on African climate among researchers, and with policy makers, practitioners and development partners. The goal is to ensure improved flow of knowledge and interactions among researchers, practitioners and decision-makers; leading toward greater impact and legacy of completed and on-going African climate research and adaptation initiatives. Registrations and grant applications open July 2019.
