This study aims to explain effects of soil textural class, topography, land use, and land use history on soil greenhouse gas (GHG) fluxes in the Lake Victoria region. We measured GHG fluxes from intact soil cores collected in Rakai, Uganda, an area characterized by low‐input smallholder (<2 ha) farming systems, typical for the East African highlands. The soil cores were air dried and rewetted to water holding capacities (WHCs) of 30, 55, and 80%. Soil CO2, CH4, and N2O fluxes were measured for 48 h following rewetting.

This report provides a synthesis on land degradation assessments conducted for two countries (Kenya and
Burkina Faso) at different scales. The task mainly involved identifying hotspot areas of degradation that require priority management interventions. The approach involves modelling, stakeholder engagement and field validation.
In the report, we refer to land degradation as the persistent loss of ecosystem function and productivity caused by disturbances from which the land cannot recover unaided.

Better soil health can increase agricultural productivity. Restoration activities can build on-farm resilience and contribute to climate change adaptation and mitigation.
Land and soil health surveys can improve crop modeling predictions under various climate scenarios and guide more targeted interventions.
Currently, most assessments of land and soil health do not consider the social, ecological, and biophysical constraints, or acknowledge the variations in the landscape.

Ce document décrit le Sénégal sur le plan de l'Agriculture Intelligente face au Climat (AIC). Le concept d’agriculture intelligente face au climat (AIC) traduit l’ambition d’assurer une meilleure intégration du développement de l’agriculture et de la réactivité face au climat. Il vise à assurer la sécurité alimentaire et atteindre les objectifs de développement plus larges dans un contexte

Food security entails having sufficient, safe, and nutritious food to meet dietary needs. The need to optimise nitrogen (N) use for nutrition security while minimising environmental risks in sub-Saharan Africa (SSA) is overdue. Challenges related to managing N use in SSA can be associated with both insufficient use and excessive loss, and thus the continent must address the ‘too little’ and ‘too much’ paradox. Too little N is used in food production (80% of countries have N deficiencies), which has led to chronic food insecurity and malnutrition.

The climate-smart agriculture (CSA) concept reflects
an ambition to improve the integration of agriculture
development and climate responsiveness. It aims to
achieve food security and broader development goals
under a changing climate and increasing food demand.
CSA initiatives sustainably increase productivity, enhance
resilience, and reduce/remove GHGs, and require planning
to address tradeoffs and synergies between these three
pillars: productivity, adaptation, and mitigation . The
