Paddy rice agriculture affects food supply, climate, water, biodiversity, and ecosystems. It varies substantially over time and space, for example, continuous expansion in northeastern China and rapid loss in southern China in the past decades. However, no maps at fine spatial resolution (e.g., 30-m) are available to document and illustrate the spatial patterns and temporal dynamics of paddy rice planting areas in China.

This document presents the Strategic Plan of the International Center for Agricultural Research in the Dry Areas for the period from 2017 to 2026. ICARDA’s mission is to enhance food, water, and nutritional security and environmental health in the face of global challenges, including climate change. Through preparedness for change and productivity gains in the rural economy, ICARDA will contribute to poverty reduction and social stability as our overarching goal. Innovative science, partnerships for impact, capacity development, and a fit-for-purpose organization are our tools.

Context: Recent conceptual developments in ecosystem services research have revealed the need to elucidate the complex and unintended relationships between humans and the environment if we are to better understand and manage ecosystem services in practice.
Objectives: This study aimed to develop a model that spatially represents a complex human–environment (H–E) system consisting of heterogeneous social–ecological components and feedback mechanisms at multiple scales, in order to assess multi-dimensional (spatial, temporal, and social) trade-offs in ecosystem services.

Modelling socio-ecological systems, in which social and ecological systems interact each other and co-evolve, are useful for supporting decisions in managing landscape ecosystems. Inter-linking socially interactive decision-making to relevant ecological processes faces a great challenge due to at least two reasons: (1) the inherent mismatches in the spatial and temporal scales the considered processes operate, (2) differences in relevant methods for modelling the processes and (3) different data availabilities for the processes.

Implementation of land management policies influences land use and hence
causes environmental change. Taking the Ordos rangelands in China as a case
study, this paper explores the potential of remote sensing to assess in dryland
areas the impacts of policies on the environment. Thirteen Landsat images of the
period 1978 2010 were acquired and those corresponding to the starting dates of
implementation of different policies were selected for land-cover change analysis;
others were used to check the detected change and track the normalized
