Robust risk assessment requires accurate flood intensity area mapping to allow for the identification of populations and elements at risk. However, available flood maps in West Africa lack spatial variability while global datasets have resolutions too coarse to be relevant for local scale risk assessment. Consequently, local disaster managers are forced to use traditional methods such as watermarks on buildings and media reports to identify flood hazard areas. In this study, remote sensing and Geographic Information System (GIS) techniques were combined with hydrological and statistical models to delineate the spatial limits of flood hazard zones in selected communities in Ghana, Burkina Faso and Benin. The approach involves estimating peak runoff concentrations at different elevations and then applying statistical methods to develop a Flood Hazard Index (FHI). Results show that about half of the study areas fall into high intensity flood zones. Empirical validation using statistical confusion matrix and the principles of Participatory GIS show that flood hazard areas could be mapped at an accuracy ranging from 77% to 81%. This was supported with local expert knowledge which accurately classified 79% of communities deemed to be highly susceptible to flood hazard. The results will assist disaster managers to reduce the risk to flood disasters at the community level where risk outcomes are first materialized.

NAPAs provide a process for the LDCs to identify priority activities that respond to their urgent and immediate needs with regard to adaptation to climate change - those needs for which further delay could increase vulnerability or lead to increased costs at a later stage. The rationale for NAPAs rests on the limited ability of the LDCs to adapt to the adverse effects of climate change. In the NAPA process, prominence is given to community-level input as an important source of information, recognizing that grassroots communities are the main stakeholders. NAPAs use existing information and no new research is needed. They are action-oriented, country-driven, are flexible and based on national circumstances. In order to effectively address urgent and immediate adaptation needs, NAPA documents are presented in a simple format, easily understood both by policy-level decision-makers and the public.

This document is a map of land and vegetation cover of the North Bank Region of the Gambia produced by the National Environment Agency of the Gambia (NEA). It is reproduced as a background map in 2015 by Constantine Kouevi, student WASCAL MRP-The Gambia, in her Master thesis. This study shows that there is a densification of human activities in this geographical space, which explains a high human concentration. Land management policies depend on the quality of natural resource management. This can lead to potential conflicts.

Recording local ecological knowledge (LEK) is a useful approach to understanding interactions of the complex social-ecological systems. In spite of the recent growing interest in LEK studies on the effects of climate and land use changes, livestock mobility decisions and other aspects of agro-pastoral systems, LEK on forage plants has still been vastly under-documented in the West African savannas. Using a study area ranging from northern Ghana to central Burkina Faso, we thus aimed at exploring how aridity and socio-demographic factors drive the distributional patterns of forage-related LEK among its holders. With stratified random sampling, we elicited LEK among 450 informants in 15 villages (seven in Ghana and eight in Burkina Faso) via free list tasks coupled with ethnobotanical walks and direct field observations. We performed generalized linear mixed-effects models (aridity- and ethnicity-based models) and robust model selection procedures. Our findings revealed that LEK for woody and herbaceous forage plants was strongly influenced by the ethnicity-based model, while aridity-based model performed better for LEK on overall forage resources and crop-related forage plants. We also found that climatic aridity had negative effect on the forage-related LEK across gender and age groups, while agro- and floristic diversity had positive effect on the body of LEK. About 135 species belonging to 95 genera and 52 families were cited. Our findings shed more light on how ethnicity and environmental harshness can markedly shape the body of LEK in the face of global climate change. Better understanding of such a place-based knowledge system is relevant for sustainable forage plants utilization and livestock production.

The development of this First National Communications has enabled my Department of State to develop an institutional framework that has brought together and consolidated the networking and dialogue between different economic sectors, CBOs and NGOs, and grassroots level communities. Technicians and scientists of different backgrounds and disciplines have pooled their expertise and worked together to develop this informative document. In this National Communication we have outlined the emissions of greenhouse gases from the major economic sectors and activities of the country, developed plausible climate change scenarios and based on these scenarios we have assessed the potential impacts of the projected climate change. The National Communication also contains measures and strategies to mitigate the concentration of greenhouse gases in the global atmosphere and adapt to the negative impacts of climate change. No detailed cost-benefit analysis was conducted on the mitigation and adaptation measures due to inadequate capacity to cost the effects of climate change. The potential impacts of climate change on crop production, biodiversity and wildlife, coastal resources, forestry, fisheries, rangelands and livestock, and water resources have been studied in great detail. Most of the impacts are negative and the populations are vulnerable. Although The Gambia is a small country, there are opportunities to invest on small-scale projects to mitigate greenhouse gas emissions and adapt to adverse impacts of climate change. These projects would be in policy development, fuel switching including the efficient use of both renewable and non-renewable energy, use of efficient modes of transportation and conservation and sustainable use of forests. Cooperation between developed countries and The Gambia will enable all Parties to meet their commitments based on the principle of common but differentiated responsibility. The mitigation and adaptation measures presented in this first national communications will require funding to build national adaptive capacity and provide appropriate technologies to address climate change.

The 2000 National Greenhouse Gas Inventory of The Gambia shows national emission total of about 20.02 Million Tons CO2 Equivalent (TCO2E) and per capita emissions of 13.5 TCO2E. This is insignificant compared to other country emissions. However, as a Party to the Climate Change Convention and its Kyoto Protocol, Gambia is willing to participate in mitigating global emissions and their concentrations in the atmosphere with the first step of conducting a mitigation assessment and developing this NAMA document. Trend analysis of climate data from 1951 to date shows a progressively warming and drier Gambia. Using General Circulation Model outputs, national temperatures are projected to increase by about 0.3OC in 2010 to about 3.9OC in 2100. Rainfall is also projected to decrease by about 1% in 2010 to about 54% in 2100. This confirms previous results of in the First National Communication that with increase in temperatures under a warming climate, rainfall in The Gambia would correspondingly decrease. The development challenges of The Gambia will be significant as the country faces complex economic, social and technological choices based on the climate change impacts already enumerated in the preceding paragraph. This is compounded by the inadequate capacities, inadequacies in the existing technologies and the non availability of domestic funding from both the public and private sectors for climate change.

This study provides an analysis of environmental observations by farmers, as well as of models of blame in Northern Ghana, an agricultural region of high vulnerability to climate change. Qualitative data were collected through a standardised questionnaire on the community’s consensus on how to explain observed changes. Responses were transcribed to allow content analysis. Natural data sets confirmed most local observations, but older age and the affectedness of the respondents were crucial in determining the views. Climate change was generally given a lower priority by the respondents compared to other manifestations of change, such as infrastructural development, human-spiritual relations and changes in social relations. Moreover, the respondents made reference to the blessing of the land and the destruction of the land. The destruction of the land was understood in a metaphorical way as the result of eroding social relationships and stagnation, as well as norm-breaking and lack of unity within the community. Thus, climate change was perceived in local social terms rather than based on global natural science knowledge. The article concludes that the anthropological analysis is meaningful and may serve as an entry point for further planning of adaptation and public education.

A Renewables Readiness Assessment (RRA) is a holistic evaluation of a country’s conditions and identifies the actions needed to overcome barriers to renewable energy deployment. This is a country-led process, with IRENA primarily providing technical support and expertise to facilitate consultations among different national stakeholders. While the RRA helps to shape appropriate policy and regulatory choices, each country determines which renewable energy sources and technologies are relevant and consistent with national priorities. The RRA is a dynamic process that can be adapted to each country’s circumstances and needs. Experience in a growing range of countries and regions, meanwhile, has allowed IRENA to continue refining the basic RRA methodology. In June 2013, IRENA published a guide for countries seeking to conduct the process in order to accelerate their renewable energy deployment.
