Guinea‐Bissau, an important regional biodiversity hotspot in West Africa, faces the challenge of raising awareness among the general public about the significance of natural resources for rural communities' survival and the need for biodiversity conservation. This knowledge gap hinders conservation efforts as initiatives are deemed irrelevant or unnecessary. A climate of political vulnerability, financial uncertainty and threats to media freedom are further obstacles to conservation biology. Researchers lack established communication platforms for academic dissemination. In this paper, we introduce the initiative News for Nature/PRIMACTION (2020–2022), which aimed to establish a communication channel between researchers and media agents. The project had two primary objectives: firstly, to raise awareness among the Guinea‐Bissau society about the importance of national biodiversity and conservation challenges; and secondly, to enhance the capacity of specific communicators and opinion makers. The project had several important outputs, including: i) a bi‐monthly newspaper section focused on "biodiversity conservation in Guinea‐Bissau", ii) three radio‐theatre episodes performed by a well‐known group and broadcasted nationally, iii) one song composed and sung by famous musicians, with an introduction by Jane Goodall, and iv) a website providing technical resources for journalists covering biodiversity and conservation news. Collaborators mentioned the lack of logistical conditions for traveling in the country as a major impediment in reporting conservation‐related news. We emphasize the significance of establishing direct contact and articulation between researchers and local media to promote conservation research in West African countries. In countries where science communication and environmental education outreach are not well‐established, it is crucial to bridge the challenges faced by the communities in different regions of the same country. This is especially urgent in cases where such challenges are significant. [ABSTRACT FROM AUTHOR]

The objective of this work is to develop a simple methodology for high resolution crop suitability analysis under current and future climate, easily applicable and useful in Least Developed Countries. The approach addresses both regional planning in the context of climate change projections and pre-emptive short-term rural extension interventions based on same-year agricultural season forecasts, while implemented with off-the-shelf resources. The developed tools are applied operationally in a case-study developed in three regions of Guinea-Bissau and the obtained results, as well as the advantages and limitations of methods applied, are discussed. In this paper we show how a simple approach can easily generate information on climate vulnerability and how it can be operationally used in rural extension services. [ABSTRACT FROM AUTHOR]

The main objective of this research is to evaluate the effects of climate change first on precipitation and temperature, and then on the runoff characteristics of two tropical watersheds located in Senegal and Guinea-Bissau. To achieve this, eighteen General Circulation Models (GCMs) were selected to measure various climate change scenarios under the Shared Socioeconomic Pathways (SSP) SSP1-2.6 and SSP5-8.5, using the reference period of 1985–2014. The GR2M hydrological model was employed to replicate past monthly surface runoff patterns for the Casamance and Kayanga-Géva watersheds. After calibrating and validating the GR2M model, the researchers simulated the predictable effect of climate change on the flow for the near future (2021–2040), medium future (2041–2060), and distant future (2081–2100) for each watershed, using the GCM multi-model ensemble mean. The quantile method was used to correct bias in temperature and precipitation data. The results of bias correction give a correlation coefficient greater than 0.9% for temperatures and 0,6% precipitation between the outputs of the multi-model ensemble and observations used. The results indicate also that all watersheds are expected to experience drier conditions in the near-future, mid-future, and far-future periods under both the SSP1-2.6 and SSP5-8.5 scenarios. Furthermore, the predictable temperature trends consistently show a warmer situation with growing radiative making in the future times. However, the primary factor influencing changes in flow for all watersheds is the projected precipitation changes. The anticipated drier conditions in the near-future, mid-future, and far-future horizons under both scenarios would lead to significantly reduced runoff volumes at the beginning and middle of the rainy season. Consequently, the projected seasonal changes in river flow for all catchments (e.g., under SSP5-8.5 scenario, a decline of -34.47%, -56.01%, and -68.01% was noted, respectively, for the horizons 2050, 2070, and 2090 for the Casamance basin) could lead to new frequent occurrences of drought and water scarcity associated with past hydrological regimes. These scenarios enhance the necessity of improving water management, water prizing, and water recycling policies, to ensure water supply and to reduce tensions among regions and countries.

Climate-related conflicts, although expected to also cause cross-border tensions/fights and intra-state civil strife among Southern countries, have been mostly framed as a problem for the rich Global North citizens produced by the poor, more environmentally vulnerable Global South potential migrants. However, violence under a climate change scenario might be more frequently expressed as small-scale and local level 'invisible' uprisings and armed conflicts, namely around land. This article focuses on a conflict over land involving a few villages of northern Guinea-Bissau, which is transforming the inhabitants of a maritime island into climate migrants/landless people. We conclude that climate change was not a direct driver but the last trigger of a long-lasting conflict with multiple and complex causes. [ABSTRACT FROM AUTHOR]

Guinea-Bissau remains among the African countries most vulnerable to climate change due to its flat topography and large meandering coastal area invaded by the tides.We present a case study of the island-village of Djobel, showing the dramatic consequences of socio-environmental change. The inhabitants' attempts to mitigate the impact of extreme weather events and sea-level rise and adapt to the new circumstances have been hampered by the seizure of their upland territory by a neighboring village. In the context of a disconnect between state and society, Djobel's inhabitants want the state to guarantee their rights to productive land, water, and safe housing conditions. This case shows the need for legal protection of the rights of poor, marginalized, and underrepresented populations at risk of becoming climate refugees in the fragile context of politically unstable, failed, and often authoritarian states.
