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.

The advent of improved lentil varieties (ILVs) in the mid-1990s solved the disease problem which almost halted lentil production in Bangladesh. Levels of adoption of ILVs have been documented in the literature, but little is known about their impacts. Applying an instrumental variables regression to data collected from a sample of 1,694 lentil plots and DNA fingerprinting for varietal identification, this study provides estimates of the plot-level impacts of adoption of ILVs in Bangladesh.

Farming systems that support locally diverse agricultural production and high levels of biodiversity are in rapid decline, despite evidence of their benefits for climate, environmental health, and food security. Yet, agricultural policies, financial incentives, and market concentration increasingly constrain the viability of diversified farming systems.

The agribusiness sector development is often portrayed as an essential component of economic development. Though Benin is a country with inestimable agricultural potential, the agribusiness sector appears unappealing to the local youths. Prior investigations diagnosed the impeding factors as a paucity of financial resource and a dearth of land and technical knowledge. This article departs from past studies by considering the importance of informal institutions for youth participation in the agribusiness sector.

This document will be used as a reference point in engaging stakeholders to influence policy through the iFEED process. The stakeholders identified will be grouped into working groups based on ratings on areas of interest and positions to integrate iFEED results to influence policies at various levels. Work Package 3 will work closely with stakeholders to organise stakeholder engagements for iFEED by convening and coordinating the activities of working groups.

Inland aquaculture is essential for the food and livelihoods of millions of small-scale producers across the global South. Very diverse actions from national governments, civil sector and international organizations have been seeking to enhance the performance of small-scale aquaculture systems. However, many of these efforts are constrained by the general lack of information about the status and characteristics of the sector.

Climate-migration nexus has been attracting increasing scholarly attention in the last decades. The various manifestations of climate change including extreme events that are expected to get more frequent and more intense, and slow-onset changes that increasingly affect livelihoods in a context of international climate coordination failure add fuel to the fire.

Agricultural activities in Guatemala constitute 32% of the total employment, but only one in every 10 individuals employed in these activities are women. This study examines cultural and economic barriers and opportunities for women’s participation in crop and livestock production systems. We used a qualitative approach involving focus groups with 15–20 women in eight communities in Chiquimula and Huehuetenango in 2022. The findings are consistent across locations.

Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands.

For years, CGIAR stakeholders have sought to define the System's comparative advantage (CA). With this concept note, ISDC aims at putting the concept of CA to effective use in research portfolio management at all levels within CGIAR, now that the One CGIAR structure makes portfolio approaches possible and especially salient.

Weather and climate strongly impact coffee; however, few studies have measured this impact on robusta coffee yield. This is because the yield record is not long enough, and/or the data are only available at a local farm level. A data-driven approach is developed here to 1) identify how sensitive Vietnamese robusta coffee is to weather on district and provincial levels, 2) during which key moments weather is most influential for yield, and 3) how long before harvest, yield could potentially be forecasted.

Farmed insects can provide an alternative protein source for humans, livestock, and fish, while supporting adaptation to climate change, generating income for smallholder farmers, and reducing the negative impacts of conventional food production, especially in the tropics. However, the quantity, nutritional quality and safety of insects greatly relies on their feed intake. Tropical forages (grasses and legumes) can provide a valuable and yet untapped source of feed for several farmed insect species.
