Integrated assessment of smallholder farming’s vulnerability to drought in the Brazilian Semi-arid: a case study in Ceará

Smallholder farming is among the most vulnerable sectors due to its great social and economic sensitivity. Despite future climate change, current climate variability is already an issue of concern that justifies adaptation efforts. In Brazil, the Semi-Arid Region is a climate hotspot, well known for both historic socioeconomic setbacks, and agriculture failures caused by dry spells and severe droughts. In 2010, the Brazilian government enacted the National Policy on Climate Change, which states as one of its key goals the identification of vulnerabilities and the adoption of adequate measures of adaptation to climate change. The improvement of vulnerability assessment tools is a response to the growing demand of decision makers for regular information and indicators with high spatial and temporal resolution. This article aims at undertaking a comparative assessment of smallholder farming’s vulnerability to droughts. An integrated assessment system has been developed and applied to seven municipalities located in the Brazilian Semi-Arid Region (within the State of Ceará). Results show regional vulnerability contrasts driven by institutional and socioeconomic factors, beyond climatic stressors.

From Rainforests to Drylands: Comparing Family Farmers’ Perceptions of Climate Change in Three Brazilian Biomes

Risk perceptions influence individual and collective adaptive responses to climate hazards. Up to now, the majority of literature addressing climate change perception and adaptation has been location-specific. Such an approach is limited with respect to the construction of a generalized theory around why and how people perceive and act towards climate change risks. This chapter seeks to contribute to overcome this limitation by offering a cross-sectional study of climate change risks perceptions among smallholder farmers settled in three contrasting biomes in Brazil: the Amazon (rainforest); the Caatinga (semi-arid); and the Cerrado (savanna). By articulating regional, local and micro scales of comparison, common traits in the perception of climate variability are identified. It is not intended, at this stage, to validate particular theories of climate change, but rather to contribute to a better understanding of climate change as a trans-regional and socially embedded environmental phenomenon. This study shows that, in spite of existing perceptive barriers, smallholders settled in dramatically different contexts share perceptions about risks linked to the following phenomena: (i) changes in the timing of seasons, (ii) decrease in rainfall levels; (iii) temperature rises. Moreover, there are specific adaptation strategies to climate change, like the timing of seeding, which appear to be addressed independently by smallholders of the three biomes. Public policies intended to support adaptive measures and the increase of food security must take subjective risk perception into account within the cultural and environmental contexts of the actors involved.

VULNERABILITY AND RESILIENCE: POTENTIALS, CONVERGENCES AND LIMITATIONS IN INTERDISCIPLINARY RESEARCH

The demand for scientific knowledge in human-environment interface is a pressing need and an increasingly urgent one given the risk posed by global environmental changes. The Vulnerability and the Resilience approaches stand out in such context. Even though each one comes from different epistemic traditions, currently they are in a fertile interdisciplinary field. This paper presents a critical discussion on the similarities, differences and limitations for the dialogue between both, given the effort to solve problems emerging from the interactions between society and environment, particularly on climate change research. Although a conceptual convergence is on course, there are still theoretical and methodological perspectives that halt the merger into a single approach. However, since both look at the same issues and are based on similar research questions, there is great potential for beneficial complementarity in advancing interdisciplinary research on socio-ecological systems.
