Spatiotemporal variability of soil moisture over Ethiopia and its teleconnections with remote and local drivers por Jimma, Tamirat B, Demissie, Teferi, Diro, Gulilat T, Ture, Kassahun, Terefe, Tadesse, Solomon, Dawit

“…It is also found that ET likely drives the SM in the eastern part of Ethiopia due to a higher atmospheric moisture demand that ultimately invokes changes in surface humidity and rainfall. A composite analysis based on the extreme five wettest and driest SM years revealed a similar spatial distribution of wet SM with positive anomalies of RF across the country and ET over the southern regions. …”

Building policy coherence into Nigeria’s agri-food system: options for more effective coordination and integration por Osei-Amponsah, Charity, Appiah, Sarah, Nicol, Alan, Balana, Bedru

“…Nigeria faces a plethora of challenges ranging from malnutrition and food insecurity, violent land tenurial conflicts and water insecurity in a changing climate. This situation threatens economic growth and development, particularly, the achievement of key targets of the Sustainable Development Goals related to SDG 1 (eliminate all forms of poverty), SDG 2 (zero hunger), SDG 5 (gender equality), SDG 6 (Clean water and sanitation), SDG 13 (climate action), SDG 14 (Conserve and sustainably use the oceans, seas, and marine resources for sustainable development) and 15 (life on land). …”

Resilient cities urban nutrition profile: Peru por Margolies, Amy, Vilca, Jessica Huamán, Pather, Kamara, Olney, Deanna K.

“…-Urban food environment (FE) studies, which mostly focus on Lima, Peru’s capital, should be expanded to other urban areas (e.g., smaller urban areas and Amazonia) and to rural areas where FEs have also started to undergo rapid changes. -Research is needed to better understand how level of urbanicity, region (Amazon/Andean), ethnicity, or settlement type intersect to affect nutrition and diets. …”

Income growth and gender bias in childhood mortality in developing countries por Ueyama, Mika

“…Second, this paper empirically tests the relationship between gender biases in child mortality and income growth using carefully-compiled new country-level panel data, paying attention to the possibility that such relationship differs between regions and changes over time. To investigate the relationship, two types of data sets are used: (1) new cross-country panel data of childhood mortality rates by sex, collected from various sources of macro statistics, such as DHS stat and WHO statistics; and (2) our own estimates for age-specific child mortality rates of children, constructed from the retrospective information on birth and death histories included in micro data of each round of the Demographic and Health Surveys (DHS). …”

Characterizing soil hydrology in the Indo-Gangetic plain of Bihar, India: Methods and preliminary results por Rossiter, D.G., Arenas-Calle, Laura, Urfels, Anton, Nayak, Harishankar, Sherpa, Sonam, McDonald, Andrew

“…Clusters based on time-series were moderately well predicted in the dry year 2022 by optimized random forest models, with the most important predictors being the number of irrigations, seasonal precipitation, pre-monsoon groundwater levels, seasonal groundwater level change, and pH, this latter as a surrogate for landscape position and other soil properties. …”
