AbstractThe sustainability of social–ecological systems within river deltas globally is in question as rapid development and environmental change trigger “negative” or “positive” tipping points depending on actors’ perspectives, e.g. regime shift from abundant sediment deposition to sediment shortage, agricultural sustainability to agricultural collapse or shift from rural to urban land use. Using a systematic review of the literature, we show how cascading effects across anthropogenic, ecological, and geophysical processes have triggered numerous tipping points in the governance, hydrological, and land-use management of the world’s river deltas. Crossing tipping points had both positive and negative effects that generally enhanced economic development to the detriment of the environment. Assessment of deltas that featured prominently in the review revealed how outcomes of tipping points can inform the long-term trajectory of deltas towards sustainability or collapse. Management of key drivers at the delta scale can trigger positive tipping points to place social–ecological systems on a pathway towards sustainable development.

There is an emerging body of literature focusing on the COVID-19 livelihoods and environmental impacts, as well as the effects of the pandemics on evidence generation. However, little attention has been paid to how COVID-19 has—and is likely to continue to—affect monitoring, evaluation, and learning (MEL) systems, specifically in the context of large sustainability science research-to-policy project consortia. Here, we provide a conceptual framework of MEL responsiveness to COVID-19 effects and discuss the specific pathways to successful MEL transition. Using the UKRI GCRF TRADE Hub as a case study, we provide some examples of possible adjustments within the new context.

L'excès de salinité des sols peut exacerber les risques existants d'insécurité alimentaire dans les deltas tropicaux densément peuplés, ce qui est susceptible d'avoir un effet négatif sur la durabilité humaine et écologique de ces régions et au-delà. Cette étude se concentre sur les régions côtières du delta du Gange-Brahmapoutre au Bangladesh et utilise les données de l'Enquête sur les revenus et les dépenses des ménages de 2010 et du Soil Resource Development Institute pour étudier l'effet de la salinité et de la richesse des sols sur la sécurité alimentaire des ménages. Les variables de résultat sont deux mesures largement utilisées de la sécurité alimentaire : la disponibilité en calories et les dépenses des ménages en produits alimentaires. Les principales variables explicatives testées comprennent des indicateurs de salinité du sol et des caractéristiques socio-économiques au niveau des ménages. Les résultats de la régression logistique montrent que dans les modèles non ajustés, la salinisation des sols a un effet négatif significatif sur la sécurité alimentaire des ménages. Cependant, cet impact devient statistiquement insignifiant lorsque la richesse des ménages est prise en compte. Les résultats suggèrent en outre que les flux d'éducation et d'envois de fonds, mais pas le sexe ou la situation professionnelle du chef de ménage, sont des prédicteurs importants de l'insécurité alimentaire dans la zone d'étude. Les résultats indiquent la nécessité de concentrer l'attention des chercheurs et des politiques sur la réduction des inégalités de richesse dans les deltas tropicaux dans le contexte de l'initiative mondiale des deltas durables et des objectifs de développement durable proposés. Como proceso progresivo, la salinización representa un riesgo ambiental significativo a largo plazo en entornos costeros y deltaicos. El exceso de salinidad del suelo puede exacerbar los riesgos existentes de inseguridad alimentaria en los deltas tropicales densamente poblados, lo que probablemente tenga un efecto negativo en la sostenibilidad humana y ecológica de estas regiones y más allá. Este estudio se centra en las regiones costeras del delta del Ganges-Brahmaputra en Bangladesh, y utiliza datos de la Encuesta de Ingresos y Gastos de los Hogares de 2010 y el Instituto de Desarrollo de Recursos del Suelo para investigar el efecto de la salinidad y la riqueza del suelo en la seguridad alimentaria de los hogares. Las variables de resultado son dos medidas de seguridad alimentaria ampliamente utilizadas: la disponibilidad de calorías y el gasto de los hogares en alimentos. Las principales variables explicativas probadas incluyen indicadores de salinidad del suelo y características socioeconómicas a nivel del hogar. Los resultados de la regresión logística muestran que en los modelos no ajustados, la salinización del suelo tiene un efecto negativo significativo en la seguridad alimentaria de los hogares. Sin embargo, este impacto se vuelve estadísticamente insignificante cuando se tiene en cuenta la riqueza de los hogares. Los resultados sugieren además que los flujos de educación y remesas, pero no el género o el estado laboral del cabeza de familia, son predictores significativos de la inseguridad alimentaria en el área de estudio. Los hallazgos indican la necesidad de centrar la atención académica y de políticas en la reducción de las desigualdades de riqueza en los deltas tropicales en el contexto de la iniciativa global de deltas sostenibles y los Objetivos de Desarrollo Sostenible propuestos. As a creeping process, salinisation represents a significant long-term environmental risk in coastal and deltaic environments. Excess soil salinity may exacerbate existing risks of food insecurity in densely populated tropical deltas, which is likely to have a negative effect on human and ecological sustainability of these regions and beyond. This study focuses on the coastal regions of the Ganges-Brahmaputra delta in Bangladesh, and uses data from the 2010 Household Income and Expenditure Survey and the Soil Resource Development Institute to investigate the effect of soil salinity and wealth on household food security. The outcome variables are two widely used measures of food security: calorie availability and household expenditure on food items. The main explanatory variables tested include indicators of soil salinity and household-level socio-economic characteristics. The results of logistic regression show that in unadjusted models, soil salinisation has a significant negative effect on household food security. However, this impact becomes statistically insignificant when households' wealth is taken into account. The results further suggest that education and remittance flows, but not gender or working status of the household head, are significant predictors of food insecurity in the study area. The findings indicate the need to focus scholarly and policy attention on reducing wealth inequalities in tropical deltas in the context of the global sustainable deltas initiative and the proposed Sustainable Development Goals. كعملية زاحفة، يمثل التملح خطرًا بيئيًا كبيرًا على المدى الطويل في البيئات الساحلية والدلتا. قد تؤدي ملوحة التربة الزائدة إلى تفاقم المخاطر الحالية لانعدام الأمن الغذائي في الدلتا الاستوائية المكتظة بالسكان، والتي من المحتمل أن يكون لها تأثير سلبي على الاستدامة البشرية والبيئية لهذه المناطق وخارجها. تركز هذه الدراسة على المناطق الساحلية لدلتا نهر الغانج- براهمابوترا في بنغلاديش، وتستخدم بيانات من مسح دخل وإنفاق الأسر المعيشية لعام 2010 ومعهد تنمية موارد التربة للتحقيق في تأثير ملوحة التربة والثروة على الأمن الغذائي للأسر المعيشية. متغيرات النتائج هي مقياسان يستخدمان على نطاق واسع للأمن الغذائي: توافر السعرات الحرارية والإنفاق المنزلي على المواد الغذائية. تشمل المتغيرات التفسيرية الرئيسية التي تم اختبارها مؤشرات ملوحة التربة والخصائص الاجتماعية والاقتصادية على مستوى الأسرة. تُظهر نتائج الانحدار اللوجستي أنه في النماذج غير المعدلة، يكون لملوحة التربة تأثير سلبي كبير على الأمن الغذائي للأسر المعيشية. ومع ذلك، يصبح هذا التأثير غير ذي أهمية إحصائية عندما تؤخذ ثروة الأسر في الاعتبار. تشير النتائج كذلك إلى أن تدفقات التعليم والتحويلات، ولكن ليس النوع الاجتماعي أو حالة العمل لرب الأسرة، هي مؤشرات مهمة على انعدام الأمن الغذائي في منطقة الدراسة. تشير النتائج إلى الحاجة إلى تركيز الاهتمام العلمي والسياسي على الحد من عدم المساواة في الثروة في الدلتا الاستوائية في سياق مبادرة الدلتا المستدامة العالمية وأهداف التنمية المستدامة المقترحة.

AbstractThe sustainability of social–ecological systems within river deltas globally is in question as rapid development and environmental change trigger “negative” or “positive” tipping points depending on actors’ perspectives, e.g. regime shift from abundant sediment deposition to sediment shortage, agricultural sustainability to agricultural collapse or shift from rural to urban land use. Using a systematic review of the literature, we show how cascading effects across anthropogenic, ecological, and geophysical processes have triggered numerous tipping points in the governance, hydrological, and land-use management of the world’s river deltas. Crossing tipping points had both positive and negative effects that generally enhanced economic development to the detriment of the environment. Assessment of deltas that featured prominently in the review revealed how outcomes of tipping points can inform the long-term trajectory of deltas towards sustainability or collapse. Management of key drivers at the delta scale can trigger positive tipping points to place social–ecological systems on a pathway towards sustainable development.

AbstractThe sustainability of social–ecological systems within river deltas globally is in question as rapid development and environmental change trigger “negative” or “positive” tipping points depending on actors’ perspectives, e.g. regime shift from abundant sediment deposition to sediment shortage, agricultural sustainability to agricultural collapse or shift from rural to urban land use. Using a systematic review of the literature, we show how cascading effects across anthropogenic, ecological, and geophysical processes have triggered numerous tipping points in the governance, hydrological, and land-use management of the world’s river deltas. Crossing tipping points had both positive and negative effects that generally enhanced economic development to the detriment of the environment. Assessment of deltas that featured prominently in the review revealed how outcomes of tipping points can inform the long-term trajectory of deltas towards sustainability or collapse. Management of key drivers at the delta scale can trigger positive tipping points to place social–ecological systems on a pathway towards sustainable development.

There is an emerging body of literature focusing on the COVID-19 livelihoods and environmental impacts, as well as the effects of the pandemics on evidence generation. However, little attention has been paid to how COVID-19 has—and is likely to continue to—affect monitoring, evaluation, and learning (MEL) systems, specifically in the context of large sustainability science research-to-policy project consortia. Here, we provide a conceptual framework of MEL responsiveness to COVID-19 effects and discuss the specific pathways to successful MEL transition. Using the UKRI GCRF TRADE Hub as a case study, we provide some examples of possible adjustments within the new context.

L'excès de salinité des sols peut exacerber les risques existants d'insécurité alimentaire dans les deltas tropicaux densément peuplés, ce qui est susceptible d'avoir un effet négatif sur la durabilité humaine et écologique de ces régions et au-delà. Cette étude se concentre sur les régions côtières du delta du Gange-Brahmapoutre au Bangladesh et utilise les données de l'Enquête sur les revenus et les dépenses des ménages de 2010 et du Soil Resource Development Institute pour étudier l'effet de la salinité et de la richesse des sols sur la sécurité alimentaire des ménages. Les variables de résultat sont deux mesures largement utilisées de la sécurité alimentaire : la disponibilité en calories et les dépenses des ménages en produits alimentaires. Les principales variables explicatives testées comprennent des indicateurs de salinité du sol et des caractéristiques socio-économiques au niveau des ménages. Les résultats de la régression logistique montrent que dans les modèles non ajustés, la salinisation des sols a un effet négatif significatif sur la sécurité alimentaire des ménages. Cependant, cet impact devient statistiquement insignifiant lorsque la richesse des ménages est prise en compte. Les résultats suggèrent en outre que les flux d'éducation et d'envois de fonds, mais pas le sexe ou la situation professionnelle du chef de ménage, sont des prédicteurs importants de l'insécurité alimentaire dans la zone d'étude. Les résultats indiquent la nécessité de concentrer l'attention des chercheurs et des politiques sur la réduction des inégalités de richesse dans les deltas tropicaux dans le contexte de l'initiative mondiale des deltas durables et des objectifs de développement durable proposés. Como proceso progresivo, la salinización representa un riesgo ambiental significativo a largo plazo en entornos costeros y deltaicos. El exceso de salinidad del suelo puede exacerbar los riesgos existentes de inseguridad alimentaria en los deltas tropicales densamente poblados, lo que probablemente tenga un efecto negativo en la sostenibilidad humana y ecológica de estas regiones y más allá. Este estudio se centra en las regiones costeras del delta del Ganges-Brahmaputra en Bangladesh, y utiliza datos de la Encuesta de Ingresos y Gastos de los Hogares de 2010 y el Instituto de Desarrollo de Recursos del Suelo para investigar el efecto de la salinidad y la riqueza del suelo en la seguridad alimentaria de los hogares. Las variables de resultado son dos medidas de seguridad alimentaria ampliamente utilizadas: la disponibilidad de calorías y el gasto de los hogares en alimentos.

Los resultados de la regresión logística muestran que en los modelos no ajustados, la salinización del suelo tiene un efecto negativo significativo en la seguridad alimentaria de los hogares. Sin embargo, este impacto se vuelve estadísticamente insignificante cuando se tiene en cuenta la riqueza de los hogares. Los resultados sugieren además que los flujos de educación y remesas, pero no el género o el estado laboral del cabeza de familia, son predictores significativos de la inseguridad alimentaria en el área de estudio. Los hallazgos indican la necesidad de centrar la atención académica y de políticas en la reducción de las desigualdades de riqueza en los deltas tropicales en el contexto de la iniciativa global de deltas sostenibles y los Objetivos de Desarrollo Sostenible propuestos. As a creeping process, salinisation represents a significant long-term environmental risk in coastal and deltaic environments. Excess soil salinity may exacerbate existing risks of food insecurity in densely populated tropical deltas, which is likely to have a negative effect on human and ecological sustainability of these regions and beyond. This study focuses on the coastal regions of the Ganges-Brahmaputra delta in Bangladesh, and uses data from the 2010 Household Income and Expenditure Survey and the Soil Resource Development Institute to investigate the effect of soil salinity and wealth on household food security. The outcome variables are two widely used measures of food security: calorie availability and household expenditure on food items. The main explanatory variables tested include indicators of soil salinity and household-level socio-economic characteristics. The results of logistic regression show that in unadjusted models, soil salinisation has a significant negative effect on household food security. However, this impact becomes statistically insignificant when households' wealth is taken into account. The results further suggest that education and remittance flows, but not gender or working status of the household head, are significant predictors of food insecurity in the study area. The findings indicate the need to focus scholarly and policy attention on reducing wealth inequalities in tropical deltas in the context of the global sustainable deltas initiative and the proposed Sustainable Development Goals. كعملية زاحفة، يمثل التملح خطرًا بيئيًا كبيرًا على المدى الطويل في البيئات الساحلية والدلتا. قد تؤدي ملوحة التربة الزائدة إلى تفاقم المخاطر الحالية لانعدام الأمن الغذائي في الدلتا الاستوائية المكتظة بالسكان، والتي من المحتمل أن يكون لها تأثير سلبي على الاستدامة البشرية والبيئية لهذه المناطق وخارجها. تركز هذه الدراسة على المناطق الساحلية لدلتا نهر الغانج- براهمابوترا في بنغلاديش، وتستخدم بيانات من مسح دخل وإنفاق الأسر المعيشية لعام 2010 ومعهد تنمية موارد التربة للتحقيق في تأثير ملوحة التربة والثروة على الأمن الغذائي للأسر المعيشية. متغيرات النتائج هي مقياسان يستخدمان على نطاق واسع للأمن الغذائي: توافر السعرات الحرارية والإنفاق المنزلي على المواد الغذائية. تشمل المتغيرات التفسيرية الرئيسية التي تم اختبارها مؤشرات ملوحة التربة والخصائص الاجتماعية والاقتصادية على مستوى الأسرة. تُظهر نتائج الانحدار اللوجستي أنه في النماذج غير المعدلة، يكون لملوحة التربة تأثير سلبي كبير على الأمن الغذائي للأسر المعيشية. ومع ذلك، يصبح هذا التأثير غير ذي أهمية إحصائية عندما تؤخذ ثروة الأسر في الاعتبار. تشير النتائج كذلك إلى أن تدفقات التعليم والتحويلات، ولكن ليس النوع الاجتماعي أو حالة العمل لرب الأسرة، هي مؤشرات مهمة على انعدام الأمن الغذائي في منطقة الدراسة. تشير النتائج إلى الحاجة إلى تركيز الاهتمام العلمي والسياسي على الحد من عدم المساواة في الثروة في الدلتا الاستوائية في سياق مبادرة الدلتا المستدامة العالمية وأهداف التنمية المستدامة المقترحة.
