Summary: Compelling evidence in Sub-Saharan Africa shows that Climate-Smart Agriculture has a positive impact on agricultural productivity. However, the uptake of CSA remains low, which is related to human-related decisions about CSA and agricultural land use. This paper assesses households' decisions to allocate agricultural land to CSA technologies across space and over time. The results show that household decisions to use CSA and the extent of agricultural land allocation to CSA remain low with a negative trend over time. Owned land and accessing land through rental markets are positively associated with allocating land to CSA technologies.

Summary: This study examines the adoption and impacts of CGIAR-related maize varieties in sub-Saharan Africa from 1995 to 2015. It finds that a significant proportion of maize varieties released during this period had CGIAR parentage, and that the cultivation of these varieties contributed to substantial economic benefits. The study also highlights the methodological challenges involved in large-scale impact assessments.

Summary: This study empirically examines the impact of external debt on economic growth in Sub-Saharan African countries. The findings suggest that both external debt and its volatility have a negative effect on economic growth, while the interaction between governance indicators and external debt has a positive impact on economic growth. The study recommends that governments in the region should avoid excessive external debt, improve governance quality, and ensure proper utilization of borrowed debt to stimulate economic growth. The Guidotti-Greenspan rule of Reserve adequacy should also be applied to regulate excessive borrowings.

Summary: This study applies a causal forest algorithm and experimental maize trial dataset to model site-specific yield response and economic returns to fertilizer use in sub-Saharan Africa. The results show that the profitability of fertilizer use varies with climate and soil conditions, but remains stable in certain locations. The findings of this study can help decision makers make informed decisions when climate conditions are uncertain and provide insights into the determinants of profitability in different regions.

Summary: This study explores the development bottleneck of agriculture in Sub-Saharan Africa and suggests measures to develop agricultural resilience. Both technological and social measures are essential to improve land resilience, and policies addressing risk mitigation and inequality reduction are crucial. A development framework for agriculture resilience is elaborated, aiming to achieve a more productive, sustainable, stable, and equally beneficial agricultural system in Sub-Saharan African countries.

Summary: To electrify 600 million people in sub-Saharan Africa, substantial investments are needed. This study establishes an open source electrification model by incorporating cost of capital values and specific risks faced by investors. The research finds that the cost of capital for off-grid electrification is much higher than previously estimated and scaling up off-grid finance can significantly reduce electrification costs.

Summary: Assessing the risk of yield loss in African drought-affected regions is crucial for stable crop production. This study applies Copula theory to describe the dependence between drought and crop yield anomalies in sub-Saharan Africa. Temperature has a greater impact on sorghum compared to maize and millet. The results demonstrate the added value of probabilistic methods for drought impact assessment.

Summary: This study critically examines the synergy effect of ICT diffusion and FDI on inclusive growth in Sub-Saharan African countries. The empirical results show that the positive effect of FDI on inclusive growth could intensify when ICT diffusion is beyond a given threshold level, while inflation and vulnerable unemployment deteriorate inclusive growth.

Summary: The severe El Nino event in 2015/16 severely damaged Papua New Guinea's local crop production, causing significant food shortages for 10% of the population. Poverty is prevalent with approximately half of surveyed individuals living in households with total per capita expenditures below the poverty line. Climate shocks have significant and possibly long-term consequences on household welfare.

Summary: Remote sensing and statistical analysis indicate that under the influence of climate change, there is a trend of northward movement of the northern limit of paddy rice cultivation in China, with an increase in elevation. Socioeconomic factors play a crucial role in this shift, while temperature increase has the most significant impact on changes in paddy rice cultivation areas.

Summary: The study reveals an increasing demand for sugar-sweetened beverages and food in PNG, leading to a rise in childhood obesity. Areas with higher household expenditure on sugary beverages have a greater probability of overweight children. Additionally, increasing income and market access in PNG are associated with higher consumption of soft drinks.

Summary: The study proposed a method called the feature selection and hierarchical classification (FSHC) method, to effectively identify paddy rice and its rotation types in South China. The FSHC method consists of three processes: cropping intensity mapping, feature selection, and decision tree model development. The results demonstrated that this method can accurately extract diverse paddy rice cropping patterns from fragmented croplands.

Summary: Rapid urbanization and population growth in China have led to increased demand for grain transportation, resulting in higher energy consumption and carbon emissions. A model-based approach was used to estimate carbon emissions associated with grain transportation in China between 1990 and 2015. The study found that carbon emissions tripled during this period, with grain production displacement contributing the most to the increase, followed by changes in grain consumption and population growth. Infrastructure development in western China partially offset the carbon emissions.

Summary: This study evaluates the potential impact of climate change on maize yield in Ethiopia and identifies the primary stress factor limiting agricultural productivity. It suggests that without technological advancements and management practice changes, climate change will lead to a decrease in maize yield due to increased water stress during critical growth stages caused by changing precipitation patterns and rising temperatures. The findings highlight the importance of considering these factors in developing climate adaptation strategies at various levels, and the potential shifts in agricultural productivity.

Summary: Dams have been constructed for various purposes, but inadequate planning has led to negative impacts on ecosystems and communities. The public health impact of dams is often neglected, and the principles and guidelines set by organizations like the World Commission on Dams are not consistently followed. A One Health perspective can improve the consideration of environmental, animal, and human health determinants in dam development.

Summary: Excessive anthropogenic nitrogen inputs have disrupted the global nitrogen cycle. Researchers have developed a comprehensive dataset for reconstructing the history of anthropogenic nitrogen inputs to the terrestrial biosphere. The dataset includes high-resolution gridded products of synthetic fertilizer, manure application/deposition, and atmospheric nitrogen deposition, providing valuable insights into the spatial and temporal patterns of nitrogen inputs and their impacts on the Earth system and living organisms.

Summary: Research shows that farmers adjust agricultural inputs in response to within-season temperature variation, increasing pesticide use and weeding effort while reducing fertilizer use in response to higher temperatures. These adjustments are made to combat the increased incidence of pests, crop diseases, and weeds due to warmer temperatures, diverting investments towards defensive inputs such as pesticides and weeding labor.
