Mapping the vulnerability of indigenous fruit trees to environmental change in the fragile savannah ecological zone of Northern Ghana.

Following the incidence of environmental change globally and its negative consequences on livelihoods of local populations, vulnerability assessment has become central to mitigation and adaptation response in the global south. However, researches on vulnerability to climate change in the African continent have seldom focused on Indigenous Fruit Trees (IFTs) although they are an essential part of the strategic forest resources and livelihood systems of local communities. This paper explores the vulnerability of two IFTs, shea (Vitellaria paradoxa) and dawadawa (Parkia biglobosa) to climatic and other stressors that are not directly linked to climate change in rural Ghana and the implications for planning. The paper analyzed vulnerability from farmer perspectives elicited through a mixed study design involving the use of Participatory Rural Appraisal (PRA) methods and a household survey. The results reveal that IFTs are highly vulnerable to drought, rainstorms, bushfires and charcoal production and less vulnerable to heavy precipitation, flash floods and sand mining. Such vulnerability arising from the combined effects of multiple stressors has led to a decreasing trend in production and yields of IFTS over the past few decades, adversely affecting livelihoods of rural women and households. To reduce vulnerability, it is an imperative to promote Environmental Change Adaptation Planning (ECAP) that prioritizes conservation and propagation of IFTs, and diversification of rural livelihoods.

Climate change extremes and barriers to successful adaptation outcomes: Disentangling a paradox in the semi-arid savanna zone of northern Ghana.

The literature on barriers to climate change adaptation has largely focused on non-climatic barriers and has provided less insight into climate-induced barriers. Responding to this lacuna, this paper examines the connections between climate change and agricultural adaptation strategies of smallholder farmers in northern Ghana. Results from the qualitative fieldwork show that climatic changes have been accompanied by increases in climate change extremes (CCEs) over the last three decades. In order to adapt, smallholder farmers use improved crop varieties and other support strategies. Paradoxically, however, CCEs have undermined these strategies in several instances, causing crop yields to fall short of their actual potential and leading to financial indebtedness. Therefore, the results showcase that overcoming non-climatic barriers to the uptake of agricultural adaptation strategies is a necessary but insufficient condition for achieving successful adaptation outcomes. This is the case since new barriers to the adaptation process are constantly emerging, and CCEs are an example of this.
