O antagonismo do modelo de crescimento econômico infinito dentro de um planeta finito, com problemas sociais e ambientais, impõe a necessidade de discussão desse modelo e seus limites, diante do desafio da sustentabilidade. Por essa razão, o presente artigo tem como objetivo abordar tendências agroecológicas na produção agropecuária sob um enfoque de processos sustentáveis. Tratou-se da adubação e da necessidade de recomendações para adubação em sistemas orgânicos e de transição, e dos sistemas agroflorestais e consórcios perenes, como tendências do processo de transição agroecológica. Também foram tratados os temas certificação, organização social, comercialização, assistência técnica e extensão rural, entendendo-os como fundamentais para a promoção dos sistemas agroecológicos.

For this reason, the present article aims to discuss agroecological trends in agricultural production under a sustainable processes approach. In particular, the focus was on fertilization and the need for recommendations for transitional and organic systems, as well as on agroforestry systems and perennial consortium as trends in agroecological transition. Topics such as certification, social organization, marketing, technical assistance and rural extension were also considered as fundamental for the promotion of agroecological systems.

The objective of this research was to select the equation that best estimates the leaf area of the coffee tree Coffea dewevrei, from the linear dimensions of the leaves. For this purpose, 140 leaves of adult plants were collected from the Capixaba Institute for Research, Technical Assistance and Rural Extension, in the city of Linhares, North of the State of Espírito Santo, Brazil. The length (L), the width (W), the product of the multiplication between the length and width (LW) and the leaf area observed (OLA) were determined from all leaves. For the modeling, a 100 leaves sample was used, where OLA was used as a dependent variable in function of L, W and LW as independent variable, being obtained the following models: linear first degree, quadratic and power. For the validation, a sample of 40 leaves was used, where the values of L, W LW were substituted in the equations generated in the modeling, thus obtaining the estimated leaf area (ELA). A simple linear equation model was fitted for each modeling equation relating ELA in function of OLA. The hypotheses H0: β0 = 0 versus Ha: β0 ≠ 0 and H0: β1 = 1 versus Ha: β1 ≠ 1, were tested using Student's t test at 5% probability. The mean absolute error (MAE), root mean square error (RMSE) and Willmott's index d for all equations were also determined. The best model that estimates the area of Coffea dewevrei was chosen through the following criteria: β0 not different from zero, β1 not different from one, MAE and RMSE values closer to zero and index d closer to the unit. The area of the leaves can be determined by its greater width (W), through the quadratic model equation ELA=-10.255+1.020(W)+1.293(W)2.
