Wheat blast is a devastating disease caused by the fungal pathogen Magnaporthe oryzae pathotype Triticum that has spread to both neighbouring and distant countries following its emergence in Brazil in the 1980s. Under climate change conditions, wheat blast is predicted to spread primarily in tropical regions. Here we coupled a wheat crop simulation model with a newly developed wheat blast model, to provide quantitative global estimates of wheat blast vulnerability under current and future climates.

We analyze rural households’ purchases of food (cereals and non-cereals) in Sub-Saharan Africa using nationally representative data with 65,000 observations covering 7 countries over a decade. We distinguish between three strata of countries: lower stratum in income and urbanization, middle stratum, and upper stratum. The paper breaks ground by the breadth and time length of the sample. We find that purchases form the majority of rural food consumption whether in favorable or unfavorable agroecological zones and over country and income strata and for most food products.

Much has been made of the potential for aquaculture to improve rural livelihoods and food and nutrition security in Africa, though little evidence exists to back such claims. This study, conducted in northern Zambia, assessed the benefits of adopting aquaculture by comparing a sample of households with (n = 177) and without fishponds (n = 174).

Agriculture consumes the largest share of freshwater globally; therefore, distinguishing between rainfed and irrigated croplands is essential for agricultural water management and food security. In this study, a framework incorporating the Budyko model was used to differentiate between rainfed and irrigated cropland areas in Africa for eight remote sensing landcover products and a high-confidence cropland map (HCCM). The HCCM was generated for calibration and validation of the crop partitioning framework as an alternative to individual cropland masks which exhibit high disagreement.

A bibliometric study on mapping the rice cropping systems in VMD is crucial for understanding the trend of EO-based rice mapping and how remote sensing technologies are essential to address the food security issue in the region. This article presents an overview of Earth observation (EO)-based rice mapping strategies since 1979, prioritizing the scope of data, approaches, and techniques derived from 3700 research articles worldwide and contrasting them with the Vietnamese Mekong Delta (VMD).

Agriculture is amongst the vulnerable sectors to climate change and its associated impacts. Most women are more vulnerable to the impacts of climate change than men. Climate Smart Agriculture ensures increased productivity thereby enabling food security, income security and wealth creation amongst the farming households. A study was carried out to understand the gender differences in access and use of climate-smart agriculture, challenges and solutions that men and women farmers use to adapt to climate change.

The global food system is failing to deliver sufficient and nutritious food to all, while damaging the earth and unsustainably drawing down its resources. We argue that trees and forests are essential to solving these challenges. We outline the current contributions of trees and forests to the global food system and present recommendations to leverage these contributions as part of the efforts to reshape food systems to better support healthy diets and environmental sustainability.

Climate services are important in helping smallholder farmers manage climate-related risks and adapt to climate change, especially for rainfed agricultural production systems. In order to increase the resilience of farmers to the changing climate in Rwanda, the United States Agency for International Development (USAID) funded a four-year project—Rwanda Climate Services for Agriculture (RCSA) from 2016 to 2019.

Forage-based cattle systems play a key role in rural economies of developing countries in terms of food security and poverty alleviation. However, they can generate negative environmental impacts by contributing to increased greenhouse gas emissions, land degradation, and reduction of biodiversity.

This factsheet gives answers on how climate exacerbates root causes of livestock-related conflict in
Kenya, using an impact pathway analysis. Three main impact pathways are identified:

The Climate-Smart Village (CSV) features a participatory platform that helps address climate change impacts on agriculture in farming communities, taking into consideration the climate-smart agriculture (CSA) options which are ecologically, culturally and gender-responsive. Its design includes providing a portfolio of practices, technologies and innovations that address food security, adaptation and mitigation and support services.

ShiFT research involves identifying and gathering all policy documents that have a potential effect on the different components of Honduras food environment. Policies were identified in priority at the national level, but any specific sub-national policies that are relevant for our SHiFT target sites will be also included.
