    International food prices have become increasingly volatile in recent decades, with “global food crises” in 2008, 2011 and most recently in 2022. The 2008 crisis prompted international agencies to ambitiously extend their monitoring of domestic food prices in developing countries to strengthen early warning systems and food and nutrition surveillance. However, food inflation by itself is not sufficient for measuring disposable income or food affordability; for that, one must measure either changes in income or changes in an income proxy.

    The CGIAR Initiative on Low-Emission Food Systems focuses on reduction of greenhouse gas (GHG) emissions while transforming food systems. It intends to work closely with key actors in the target countries, supporting them with new knowledge, information and tools to make robust evidence-based decisions as they confront challenges in food system transformation discourses, policy development and the reduction of GHG emissions. In Kenya, Nandi County has been selected as a site for a Living Lab for People (LL4P) on low-emission food system development.

    Conflicts such as the Boko Haram insurgency, herder–farmer conflicts, and armed banditry attacks are major concerns affecting the livelihoods and food security of households in Nigeria. In this paper, firstly, we reviewed and synthesized the nature, spatial extent, and implications of conflicts on food security in Nigeria. Secondly, using survey data and econometric models, we examined the effects of conflict-induced shocks, such as forced migration and fatality on household food security indicators.

    Indicators of CSA practices/technologies are crucial to measure the performance of CSA practices/technologies and use as a guideline for data collection on the evaluation of CSA practices and technologies. Various indicators of CSA practices under the five categories including crop production, livestock production, integrated soil fertility management, erosion control, water management, and forestry/agroforestry management were identified using experts knowledge and literature review.

    Food losses and waste (FLW) reduction and mitigating climate impact in food chains are priorities in achieving sustainable development goals. However, many FLW-reducing interventions induce additional greenhouse gas (GHG) emissions, for example, from energy, fuel, or packaging. The net effect of such interventions (expressed in GHG emissions per unit of food available for consumption) is not obvious, as is illustrated in a number of case studies.

    play a key role in building smallholders’ resilience. However, the impact of PSNP on on-
    farm agrobiodiversity is not yet well investigated. In this paper, we develop an analytical
    framework that links PSNP participation to on-farm agrobiodiversity. Both diverse farm-
    ing systems and PSNP require labour inputs while providing income stabilization, which
    might result in a negative relationship between the two. Conversely, higher income from
    PSNP might allow farmers to increase their long-term on-farm investments, as opposed to

    Smallholder irrigation is emerging as a development priority in Sub-Saharan Africa. Based on a survey of 1554 smallholders from nine countries, this paper compares rainfed farming with gravity-flow, manual-lift and motor-pump irrigation. Motor-pump-irrigation farmers reported the highest net value added per acre and per family worker, with gravity-flow and manual-irrigation farmers earning marginally more than rainfed-only farmers.

    Land-use-change-induced increases in shallow groundwater levels across parts of the Sahel in recent years have coincided with expanded use of groundwater for irrigation. This study was conducted to assess the potential linkages and livelihood implications based on a field survey of nine villages building on previous hydrological studies. The results show that irrigators lack effective means of production and mostly rely on manual methods. Borehole usage is more profitable and reliable than shallower wells.

    This study uses maize as the test crop. Maize is the key focus of most studies on crop response to micronutrients in SSA with a limited number of studies on wheat, rice, cowpea, sorghum, and soybean responses. Maize, constituting 45% of the cereal production in SSA in 2014, is the staple food crop (accounting for over 40% of the calories consumed in some countries such as Malawi and Zambia ( and the main component of food aid interventions in SSA (Leonardo et al. 2015).
