The national-scale wheat area dataset of Ethiopia for the 2020/21 rainfed cropping seasons shows the spatial distribution and density of rainfed wheat at 10 m spatial resolution for the 2020 Belg and 2020/21 Meher seasons at the national scale. The binary dataset depicts whether a pixel is classified as wheat or non-wheat (labeled as "1" and "0", respectively) during the period ranging from April to December 2020. For datatset generation, state-of-the-art, efficient satellite data pre-processing, in-depth in situ data cleaning, and Random Forest classification methods have been applied to a multispectral, gap-filled Sentinel-2 satellite time series from April to December 2020 and the multi-source Ethiopian Crop Type 2020 (EthCT2020) ground reference dataset (Blasch et al., 2024). This dataset with a classification overall accuracy of 80% was developed with the goal to complement the Ethiopian Wheat Rust Early Warning and Advisory System’s baseline data for the disease dispersal and environmentally suitability forecast models as well as building the basis for new information layers regarding the host susceptibility. Overall, the dataset can serve as a baseline input parameter for crop models, climate models, crop disease and pest surveillance and forecasting, and agricultural monitoring in the smallholder cropping systems of Ethiopia.

The sorghum data was collected from small-scale sorghum farmers in the Tanzanian regions of Dodoma and Shinyanga in November and December 2023. In the Dodoma region, two districts were selected: Kondoa and Kongwa, while in the Shinyanga region, the districts selected were Kishapu and Shinyanga. The sample size consists of 1,100 small-scale farmers. The farmer profiling questions covered the following topics: socio-demographic information, with variables such as gender, age, family size, and education; farm information variables, including farm size, crops grown, animals kept, input use, and key income sources; and information on sorghum farming variables, such as seed purchase, cropping system, seed volume and plot size, harvest volume, and usage questions. The data also includes the identification and selection of preferred sorghum seed variety concepts presented in video format. For the video data collection, eight product descriptions were conceptualized into videos, and the presentations were made by a seed multiplier. Each farmer saw only three of the eight videos at a given time (incomplete block design). The videos viewed by each farmer were selected at random, resulting in a total of 3,300 videos presented to 1,100 small-scale farmers overall.

The groundnut data was collected from small-scale groundnut farmers in the Tanzanian regions of Dodoma, Shinyanga, Mtwara, Lindi, and Songwe in May and November 2023. The sample size consists of 2,200 small-scale farmers. The phase one data responses are from farmers in Dodoma and Shinyanga, collected in May 2023, while the phase two data is from farmers in Mtwara, Lindi, and Songwe, collected in November 2023. The farmer profiling questions covered the following topics: socio-demographic information, with variables such as gender, age, family size, and education; farm information variables, including farm size, crops grown, animals kept, input use, and key income sources; information on groundnut farming variables, such as seed purchase, cropping system, seed volume and plot size, harvest volume and usage; and food security and hunger questions. The data also includes the identification and selection of preferred groundnut seed variety concepts presented in video format. For the video data collection, eight product descriptions were conceptualized into videos, with presentations made by both a male and a female seed multiplier. Each farmer saw only three of the eight videos at a given time (incomplete block design). The videos viewed by each farmer were selected at random, resulting in a total of 6,600 videos presented to 2,200 small-scale farmers overall.

The necessity for differentiated responses arises due to the significant surge in nitrogen fertilizer prices, posing a serious threat to food security. To sustain the production of staple cereals in agricultural systems with varying levels of fertilization, it becomes imperative to explore integrated management strategies encompassing both organic and inorganic nitrogen sources in high- and low-intensity cereal production. According to estimates, adopting such an integrated approach could yield substantial reductions in nitrogen fertilizer usage: by 11% in India, 49% in Ethiopia, and 44% in Malawi. This strategy involves utilizing more cost-effective fertilizers with a high nitrogen content, such as urea, in conjunction with compost and legumes, particularly aimed at optimizing nitrogen utilization in deficient systems. Furthermore, embracing more efficient and targeted nitrogen fertilizer application would prove beneficial for systems with nitrogen surpluses. Geospatially diverse fertilization strategies should prioritize supplying nitrogen-rich fertilizers to low-yielding and nitrogen-deficient regions, while ensuring balanced fertilization of nitrogen, phosphorus, potassium, and micronutrients in high-yielding systems.

For the first time in history, the emergence of wheat-blast in Bangladesh has generated major food security concerns. The Bangladesh Agricultural Research Institute (BARI) together with the International Maize and Wheat Improvement Center (CIMMYT) developed and released the wheat variety BARI Gom 33 that is resistant to wheat blast and other common diseases. The new variety provides a 5-8% yield gain over the available popular varieties, as well as being zinc enriched. This study examines the potential economic benefits of BARI Gom 33 in Bangladesh. First, applying a climate analogue model, this study identified that more than 55% of the total wheat area in Bangladesh (across 45 districts) is vulnerable to wheat blast. Second, applying an ex-ante impact assessment framework, this study shows that with an assumed cumulative adoption starting from 2019-20 increasing up to 30% by 2027, the potential economic benefits of the newly developed wheat variety by 2029-30, far exceeds its dissemination costs. Even if dissemination of the new wheat variety is limited to only the ten currently blast-affected districts, the yearly average net benefits amount to USD 0.23-1.6 million. Based on the findings, the international donor agencies are urged to support the national system in scaling out the new wheat variety and wheat research in general to ensure overall food security in South Asia.

The collected data originate from a study conducted in the Eastern and Northern provinces of Zambia during the low season (December 2019 to February 2020). The sample includes 528 households selected through random sampling in various agricultural camps, with information on agricultural production, marketing decisions, seasonal food prices, food consumption, nutritional content of crops, and anthropometric measures of children under five years old. The households are located in the districts of Katete in the Eastern Province and Mbala in the Northern Province. Additionally, sociodemographic data and information on access to services were collected, along with variables related to crop diversification and household resources. The data were used to analyze the relationship between nutrient deficiencies from own production (NDOP), food sale and consumption decisions, and child growth outcomes, employing econometric methods to address potential endogeneity biases.
