Although Indonesia has recorded good performance in its national economic development, especially in the agriculture sector during the Covid-19 pandemic, the impact of the pandemic on farming and food systems has not been evaluated yet. This study has evaluated the resilience of the two dominant existing farming systems in West Timor, i.e. (i) wetland farming system and (ii) dryland farming system. This research aims to understand the resilience of farming after the Covid-19 pandemic and to develop strategic policies that could be adopted to increase the resilience of the farming system in West Timor. A quantitative analysis using the Structural Equation Modelling (SEM) was employed to evaluate the relationship and impact of the following seven generic aspects: labour movement, sustainability, economy, socioculture, output markets, input markets, farming system resilience, and 27 reflective indicators. The analysis shows that dryland farming systems are more resilient than wetland farming systems. It might be understood from the size of the regression coefficient, as the impact of exogenous construct variables of the environment, socioculture, input, and output on the resilience of dryland farming systems is more significant than on wetlands. Economic performance rather than labour movement factors will create better resilience of farming systems for wetland or dryland after the Covid-19 pandemic. Finally, the economic recovery process and the ongoing input supply mechanism after the Covid-19 pandemic have increased the resilience of the dryland food system more than the resilience of the wetland farming system.

The Whitmore Point Member of the Moenave Formation: Early Jurassic Dryland Lakes on the Colorado Plateau, Southwestern USA

The Lower Jurassic Whitmore Point Member of the Moenave Formation in Arizona-Utah, USA, comprises fish- and coprolite-bearing shales, siltstones, sandstones, and minor limestones. These facies were deposited in ephemeral and perennial lakes subject to episodic desiccation and incursions of coarse clastics during floods. Meromictic conditions developed during perennial episodes, probably due to salinity stratification, which enhanced preservation of organic matter in gray to black shales. These lakes formed on the floodout of a north-northwest oriented (relative to modern geography) system of mainly ephemeral streams on a broad and open floodplain. The Whitmore Point Member both overlies and interfingers laterally with alluvial red-bed facies of the Dinosaur Canyon Member of the Moenave Formation. The vertical transition from alluvial to lacustrine sedimentation recorded by the Dinosaur Canyon and Whitmore Point members of the Moenave Formation most probably resulted from a eustatically-controlled rise in base level during the Early Jurassic (Hettangian). The Dinosaur Canyon Member also interfingers laterally with eolian dune deposits of the Wingate Sandstone, which was deposited by winds that reworked coastal plain sediments to the north of the study area. Thus, on this part of the Colorado Plateau, fluvial, lacustrine and eolian sedimentary facies were deposited contemporaneously in laterally adjacent paleoenvironments.
