Intenção de adoção de práticas agrícolas resilientes ao clima por produtores de trigo em Punjab, Paquistão: uma Teoria do Comportamento Planejado estendida
Este estudo teve como objetivo investigar os determinantes psicossociais da intenção de produtores de trigo de adotar um conjunto específico de práticas agrícolas resilientes ao clima (CRAPs, na sigla em inglês) na província de Punjab, no Paquistão. A abordagem baseou-se em uma extensão da Teoria do Comportamento Planejado (TCP), incluindo os seguintes construtos: atitude, normas subjetivas, controle comportamental percebido, confiança no desempenho das CRAPs e o manejo atual de práticas resilientes ao clima (comportamento passado). Entre maio e julho de 2024, realizou-se um estudo transversal com 384 produtores de trigo, utilizando um delineamento em seis estágios: seleção intencional de zonas agroecológicas, distritos e *tehsils* (subdivisões distritais), seguida de amostragem aleatória de *union councils* (unidades administrativas locais), vilarejos e produtores. As cinco CRAPs analisadas foram: cultivo conservacionista, uso de variedades certificadas tolerantes ao calor e à seca, semeadura na época adequada, fertilização balanceada por estágios de desenvolvimento da cultura e irrigação nas fases críticas. Para a análise dos dados, utilizou-se a modelagem de equações estruturais por mínimos quadrados parciais (PLS-SEM), com 10.000 subamostras geradas por meio de bootstrapping. A atitude foi o preditor positivo mais forte da intenção (β = 0,446; IC 95% 0,319–0,543; p < 0,001), seguida pela confiança no desempenho das CRAPs (β = 0,344; p < 0,001) e pelo controle comportamental percebido (β = 0,172; p = 0,001). As normas subjetivas não apresentaram significância estatística (β = 0,038; p = 0,455). Apesar de haver correlação bivariada positiva com a intenção, o manejo atual de CRAPs apresentou um coeficiente parcial negativo (β = −0,246; p < 0,001). Esse resultado reflete um padrão de supressão estatística ou um "efeito teto", e não uma resistência à mudança. O modelo explicou 48,6% da variância na intenção (R² ajustado = 0,479; Q²predict = 0,389). Dada a natureza transversal e o foco na intenção, os resultados referem-se à intenção de adoção, e não à adoção efetiva das práticas. Eles propõem que programas de extensão reforcem a intenção ao demonstrar aos produtores o sucesso agronômico das práticas agrícolas resilientes ao clima (CRAPs) e auxiliá-los a desenvolver a capacidade de adotá-las.
