Previous issue date: 2013-03-05 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / At the semiarid regions of developing countries the rural population has always been
vulnerable to the climatic variations e its consequences. The effects of the semiarid climate,
together with other biophysics, social and political-economic factors, impair the agricultural
production, generating a situation of food insecurity and poverty in the rural areas. With the
occurrence of climate change, natural resources of the semiarid regions can became scarcer,
what would directly affect the agricultural production and those who depend on it. Therefore,
the present study sought to study one of the most susceptible areas to the effects of the
semiarid climate and desertification of Rio Grande do Norte, the potiguar s Serido. The study
aimed to analyze the socioeconomic and environmental factors that put farmers in a position
of vulnerability to the effects of climate; assess their perceptions about climate variations that
have already occurred and their knowledge about climate change and global warming, also to
identify which adaptation strategies to climate they have adopted at the rural establishment.
The survey was conducted in 29 communities of four counties of the potiguar s Serido
Caico, Parelhas, Lagoa Nova and Acari. Semi-structured interviews were conducted with
local leaders and 241 questionnaires were applied with the family farmers. It was found that
in addition to environmental factors such as the scarcity of water resources and climatic
conditions, other factors such as the environmental degradation, the small size of the
properties, the lack of technical assistance and financial resources and also the low education
levels reduce the resilience capacity of family farming to the effects of the Semiarid climate.
With the occurrence of climate change, the challenges for family farming at Serido will
intensify. If farmers cannot adapt, the impacts may preclude this category of agricultural
production causing serious harm to food security and further increasing the vulnerability
situation of these populations. Although the farmers perceived changes in climate, the lack
resources and information appears as the main reasons preventing the adoption of adaptation
strategies. The lack of knowledge about climate change and global warming and the impacts
that these phenomena may cause are also limiting factors for adaptation. It is therefore
essential to identify the factors that influence the adoption of adaptation strategies, and seek
alternatives to living with the semiarid that can strengthen the resilience of family farming
and social reproduction that allow agricultural segment, even in a climate change scenario / Nas regi?es semi?ridas dos pa?ses em desenvolvimento as popula??es rurais sempre
estiveram vulner?veis ?s varia??es clim?ticas e suas consequ?ncias. Os efeitos do clima
Semi?rido, aliados ? outros fatores biof?sicos, sociais, pol?ticos e econ?micos, prejudicam
a produ??o agr?cola, gerando uma situa??o de inseguran?a alimentar e pobreza no meio rural.
Com o advento das mudan?as clim?ticas, os recursos naturais das regi?es semi?ridas poder?o
se tornar ainda mais escassos, o que afetaria diretamente a produ??o agr?cola e os que dela
dependem. Nesse contexto, a presente pesquisa buscou estudar uma das ?reas mais
suscept?veis aos efeitos do clima semi?rido e da desertifica??o do Rio Grande do Norte, o
Serid? potiguar. O estudo teve como objetivo analisar os fatores socioecon?micos e
ambientais que colocam os agricultores familiares numa situa??o de vulnerabilidade aos
efeitos do clima; avaliar suas percep??es sobre as varia??es clim?ticas j? ocorridas e seus
conhecimentos sobre mudan?as clim?ticas e aquecimento global, al?m de verificar quais as
estrat?gias de adapta??o ao clima foram realizadas no ?mbito do estabelecimento rural. A
pesquisa foi realizada em 29 comunidades de quatro munic?pios do Serid? potiguar Caic?,
Parelhas, Lagoa Nova e Acari. Foram realizadas entrevistas semiestruturadas com lideran?as
locais e aplicados 241 question?rios com os agricultores familiares. Verificou-se que al?m dos
fatores ambientais como a escassez dos recursos h?dricos e as condi??es clim?ticas outros
fatores como degrada??o ambiental o tamanho reduzido das propriedades, a falta de
assist?ncia t?cnica e de recursos financeiros, al?m do baixo n?vel de escolaridade dos
agricultores reduzem a capacidade de resili?ncia da agricultura familiar aos efeitos do clima
Semi?rido. Com a ocorr?ncia das mudan?as clim?ticas, os desafios para a agricultura familiar
do Serid? potiguar ir?o se intensificar e, caso os agricultores n?o consigam se adaptar, os
impactos poder?o impossibilitar a produ??o agr?cola dessa categoria, causando graves
preju?zos para a seguran?a alimentar e aumentando ainda mais a situa??o de vulnerabilidade
dessas popula??es. Apesar de perceberem as altera??es no clima, a limita??o de recursos
financeiros e a falta de informa??es aparecem como principais impedimentos ? ado??o de
estrat?gias de adapta??o. A falta de conhecimento sobre as mudan?as clim?ticas, aquecimento
global e sobre os impactos que esses fen?menos podem causar tamb?m s?o fatores limitantes
? adapta??o. Torna-se assim, essencial identificar os fatores que influenciam a ado??o de
estrat?gias de adapta??o, al?m de buscar alternativas para a conviv?ncia com o semi?rido que
possam fortalecer a resili?ncia da agricultura familiar e permitir reprodu??o social desse
segmento agr?cola, mesmo num cen?rio de mudan?as clim?ticas
