CGIAR’s NEXUS Gains Initiative aims to realize gains across water, energy, food, and ecosystems (with a focus on forests and biodiversity) in selected transboundary river basins by leading global nexus thinking and providing tools, guidelines, training and facilitation for analysis, and research for development. Work Package 5 of NEXUS Gains specifically aims to develop the capacity of WEFE actors. A core component of the capacity strengthening program is a leadership development package tailored to WEFE nexus leaders, with emphasis on emerging women leaders.

Improving fertilizer use efficiency has remained a challenge, particularly for small-scale farming in undulating ‘abnormal’ landscapes of East Africa. Milne's 1930s concept on ‘Catena’ was considered as a breakthrough in understanding soil variability and its implication on productivity in East African highlands. However, there is limited information on how the ‘Catena’ features could be used for fine tuning fertilizer recommendations.

Groundwater resources and irrigation systems are a fundamental consideration for sustainable and inclusive food system transitions in South Asia. Over the course of the latter part of the 20th century and the early 21st century, groundwater has become the primary source of irrigation water across South Asia and globally. The aquifers in Western and Peninsula regions in South Asia have faced water scarcity and groundwater depletion. But in the Eastern Gangetic Plains, aquifers are still considered underutilized by most planners and policymakers.

In this methodological note, we propose a quantitative framework to develop a Climate and Security Index (CSI), for measuring and monitoring climate security vulnerability. Primarily meant for long-term planning and decision making for resilience building, it incorporates a broad range of drivers of the climate-security nexus, including those from climatic, conflict, socioeconomic, agricultural, and contextual (i.e., mitigating factors, adaptive capacity) dimensions, to indicate climate-security risks at subnational level.

A three-day experience-sharing workshop was held in Cape Town, South Africa, from 28 to 30 September 2022 to support the co-development of National Framework for Weather, Water and Climate Services (NFWWCS) for the Southern Africa countries. This workshop is a follow-up on the successful co-development and endorsement of AICCRA-supported National Framework for Climate Services (NFCS) in Ethiopia and the subsequent two regional workshops for IGAD and SADC member States held in Zanzibar and Kampala to explore regional landscape in the development and implementation of NFWWCS.

In this literature review, we examine climate change adaptation governance and resilience building among communities in Senegal. We examine existing policies, governance structures, and decision-making processes in climate change adaptation issues at different governance levels for food related sectors (agriculture, natural resource, including forestry, water and energy). Second, we identify key programmes/projects, knowledge gaps, social inclusion and equity gaps in climate change adaptation issues at different governance levels for food related sectors.

Study region: Sierra Nevada de Santa Marta (SNSM) region of Colombia.

This study aimed at modeling scenarios of future land use and land cover (LULC) change and estimating ecosystem service (ES) values for the year 2051 compared to 2021 in Central Ethiopia. The future LULC changes for the year 2051 were simulated for four scenarios, namely Business-as-Usual (BAU), Rapid Agricultural Expansion (RAE), Ecosystems Protection and Agricultural Development (EPAD) and Landscape Ecosystems Restoration and Conservation (LERC).

The purpose of this work package is to analyze current policies and co-identify ways policy goals and objectives that hold potential to support transformative change and address policy incoherence across sectors to drive food, land and water systems transformation. In this regard, a flagship report on Central policies & schemes in Food, land & water sector of India, is currently being prepared.

Finance for climate action can be an important means of bolstering the resilience of communities exposed to climate hazards, addressing developmental challenges, and redistributing wealth toward the Global South. However, investments in contexts where climate and conflict risks overlap must recognize linkages between the two and be careful not to cause or worsen violence. More aspirationally, they should leverage food, land, and water systems to build peace by fostering positive social conditions.

Study Region: The study covers the freshwater lakes of Ethiopia, which constitute about 87 billion cubic meters of water volume. The lakes are facing continued ecosystem degradation threats. Study Focus: The aim of this study was to make an inventory of existing literature regarding the freshwater lakes of Ethiopia and identify gaps and priorities for future research directions. This was done through a systematic review of published scientific literature related to the lakes and characterizing each study based on different criteria.

Yam (Dioscorea spp.) is a staple food crop and a source of income for millions of people in West Africa. Traditionally, in West Africa, yams are grown without any external inputs, leading to low tuber yields. The rapid decrease of tuber yield observed after the first yam cropping season has been ascribed to nutrient depletion and/or to the accumulation of yam-specific pests and diseases. This has led farmers to grow yam on new surfaces under fallow each year.
