ABSTRACT.- This work aims to contextualize and analyze the potential contribution of pecan to SDG2 under the dual perspective of carbon storage and human nutrition. Particularly, the study focuses on the pecan agroecosystems in the Americas, representing the most important pecan-producing countries (the United States, Mexico, Brazil, Argentina, Uruguay, and Peru). We observed that pecan is a reliable sink for storing atmospheric C and also for quality nuts with high nutritional density. The Americas, hold a population of ca.

Carbon net emission is a critical aspect of the environmental footprint in agricultural systems. However, the alternatives to describe soil organic carbon (SOC) changes associated with different agricultural management practices/land uses are limited. Here we provide an overview of carbon (C) stocks of non-forested areas of Uruguay to estimate SOC changes for different soil units affected by accumulated effects of crop and livestock production systems in the last decades.

ABSTRACT.- Conventional viticulture involves a high use of inputs that negatively impact ecosystem services and biodiversity. Traditionally, vineyards are rainfed systems and vegetation is removed or sprayed with herbicides to avoid excessive competition for water and nutrients. Introducing cover crops can positively promote several ecosystem services and particularly soil and crop health and biodiversity.

ABSTRACT.- Aim:The intensification of livestock systems generates structural and functional changes in native grassland, which alter their capacity to respond to disturbances. Our objective was to evaluate the resilience to an extraordinary consecutive-droughts event, across an intensification gradient of livestock systems. Our prediction was that sites with more intensive management (less diverse) will have lower resilience (as resistance and/or recovery) to drought. Location:South-central region of Uruguay.

ABSTRACT.- Plants grow associated with complex communities of organisms, and their development depends largely on management practices, available nutrients in the soil, environmental conditions, and the balanced equilibrium established among all these factors. In unbalanced environments, diseases, insects, and weeds can decrease agricultural productivity or even destroy crops.

RESUMEN.- La teoría de Estados Alternativos de Biomas (EAB) contribuye a explicar la presencia de biomas abiertos (pastizales, arbustales) en ambientes suficientemente cálidos y húmedos para el desarrollo de biomas de bosque. En estos ambientes se pueden encontrar áreas dominadas por biomas abiertos que, según esta teoría, responden principalmente al fuego y a la herbivoría.
