Climate change affects changes in rice-based systems of coastal Bangladesh. Both external pressures and system-immanent attributes influence farmers’ adoption of new production practices, leading to the emergence of new land use patterns. Field and

Prosopis juliflora is a shrub/tree originating from the Americas. Since its introduction for fuel wood afforestation into eastern Africa, it has been invading crop- and rangelands with negative effects on the environment and on livelihoods. Understan

Mineral nitrogen (N) supply reportedly increases rice susceptibility to the fungal pathogen Magnaporthe oryzae causing blast disease. These biotic and abiotic factors cause changes in spectral reflectance of leaves; however, the effects of N × patho

Abstract The existence of a dark matter model with a rich dark sector could be the reason why WIMP dark matter has evaded its detection so far. For instance, colored coannihilation naturally leads to the prediction of heavier dark matter masses. Impo

The non-observation of WIMP dark matter might be explained by the existence of complex dark sectors. We illustrate, on a model of colored coannihilation, that the Sommerfeld effect and bound state formation are fundamental in calculating the relic de

Most of the approximately 105 million Egyptians depend on wheat in the form of baladi bread for their daily diet. Millions of smallholders along the River Nile have produced wheat for millennia; however, in more recent history, the wheat demand and s

Abstract We study the dark matter phenomenology of Standard Model extensions addressing the reported anomaly in the $$R_K$$ R K observable at one-loop. The article covers the case of fermionic singlet DM coupling leptophilically, quarkphilically or a

In Egypt, recent shortfalls in the wheat supply from Russia and Ukraine have necessitated substantial increases in domestic production. As agricultural practices influence the yield of bread wheat, we assessed current production strategies in the whe

While interflow from the slopes can be crucial for water and nutrient availability in low-input farming systems in wetlands in East Africa, very little data exist on hillslope hydrology and associated nutrient transport in deeply weathered saprolites
