The primary goal of this study was to compare the multiplication rates of yam varieties propagated through organogenesis and somatic embryogenesis (SE). Callus was induced from axillary bud explants of three genotypes of Dioscorea rotundata (Asiedu, Ekiti2a, and Kpamyo) and two genotypes of Dioscorea alata (Swaswa and TDa2014) cultured in Murashige and Skoog (MS) medium containing 9.1 µM 2,4-dichlorophenoxylacetic acid and 5.4 µM naphthaleneacetic acid. Plantlets were regenerated in MS containing 4.4 µM benzylaminopurine and 34 µM uniconazole-P through SE.

We cannot live without healthy soil and land. It is on these resources that we produce most of our food and build our homes. We need them to provide clean water and precious plant nutrients, to conserve biological diversity and to cope with climate change. And they form the basis for the livelihoods of millions of people. But despite such known facts, these valuable resources are in a dire state. A third of all soils world-wide are already degraded, and each year, further huge expanses of fertile land go lost.

This powerpoint presentation explains why and how to use the Solutions Journalism approach for reporting on key land-related challenges and solutions, including pollution, climate change, deforestation, water scarcity, waste disposal etc. The presentation was given at the Introductory Briefing: Reporting on Environmental and Land Issues: The Solutions Journalism Approach, on 9 March 2022.

In Cameroon, the pressure on wetlands, which cover nearly 70% of the national territory, appears to be increasing, whether for subsistence needs, firewood, grazing, logging or expansion of development projects. Currently, in terms of land use, forest has decreased by 619 km² and cultivated land has increased by 321 km². The surface area of degraded forests and land is estimated at around 12 million hectares, with a general trend towards an increase in the phenomenon due to both natural and anthropogenic factors.

Context Pastoralism obeys logics that are sometimes misunderstood by public decision-makers and that are at the origin of many interventions that are often inappropriate. The controversial effects of pastoral public policies are accentuated by several exogenous and endogenous hazards.

Grasping the indirect and non-linear linkages between climate and conflict merits uncovering how inequalities entrenched in existing social structures may inform and mediate this intricate relationship. Despite growing understanding around the need to focus on the entire climate security inequality nexus, existing literature has so far been tipping towards either unpacking inequality and conflict or inequality and climate linkages. Furthermore, research for development work is yet to unpack in detail context-specific nuances of this complex nexus.

This synthesis brief captures insights and lessons from the implementation of the CGIAR Research Program on Water, Land and Ecosystems (WLE) over the past decade. By assessing the program’s performance, thematic scope and its management, governance and structure, as well as the ways in which the program has monitored and communicated its research outputs, this brief aims to consolidate WLE’s experiences and inform the transition to One CGIAR and the
development of future research-for-development initiatives.

Land and water management practices have been widely implemented in rural Mali since the1980s to improve agricultural productivity and erosion control. Under conditions of recurring droughts, these practices are expected to increase farmers’ ability to cope with shocks. One of the most common practices applied in the central and southern parts of Mali is contour bunding (CB). In this study the impact of the CB technology is evaluated with a focus on biophysical and socio-economic benefits.

Supporting young people to enter food value chains can help reduce high levels of youth unemployment across sub-Saharan Africa. The International Water Management Institute (IWMI) and WorldFish conducted a study to understand the drivers of, and hindrances to, youth entry into aquaculture value chains in Nigeria to support development of youth-inclusive policy for rural areas.

This paper developed an inventory of adaptation options implemented in the last two decades in Morocco. The agricultural development strategies and plans, set up since the early 2000s, targeting investments to modernize different economic sectors, were the Rural development strategy (RDS, 2008-2008), Green Morocco Plan (GMP, 2008-2020), and Generation Green (GG, 2022-2030). The GMP comprised a slew of adaptation options to address the climate risks and new socio-economic challenges with public and private participation. The main adaptation options were 1).

The security implications of climate variability and change, commonly referred to as the climate-security nexus, have been widely discussed in both policy circles and academia. While climate is rarely the sole cause of conflict, it can exacerbate conflict risks and outcomes by affecting societies’ economic performance, amplifying patterns of marginalization and exclusion, and challenging the capacity of already strained institutions (von Uexkull & Buhaug, 2021).
