Disentangling Climate and Human Drivers of Land Degradation in East and Southern Africa
Timely monitoring of land degradation (LD) is essential to guide targeting the sustainable land management (SLM) practices to the suitable context that assists in achieving an LD neutral world. This study applied a 40‐year time series of remote sensing data representing vegetation indices and rainfall to identify the hotspots for the climatic and human‐induced LD or improvements in the East and Southern Africa (ESA) region. This was complemented …
Assessing UN indicators of land degradation neutrality and proportion of degraded land for Botswana using remote sensing based national level metrics
Achieving land degradation neutrality (LDN) has been proposed as a way to stem the loss of land resources globally. To date, LDN operationalization at the country level has remained a challenge both from a policy and science perspective. Using an approach incorporating cloud‐based geospatial computing with machine learning, national level datasets of land cover, land productivity dynamics, and soil organic carbon stocks were developed. Using the …
Crop harvested area, not yield, drives variability in crop production in Iran
Increasing population and a severe water crisis are imposing growing pressure on Iranian cropping systems to increase crop production to meet the rising demand for food. Little is known about the separate contribution of trends and variability of the harvested area and yield to crop production in severely drought-prone areas such as Iran. In this study we (a) quantify the importance of harvested area and yield on trends and variability of crop pr…
Object-based identification of vegetation cover decline in irrigated agro-ecosystems in Uzbekistan
Spatial targeting of land rehabilitation: A relational analysis of cropland productivity decline in arid Uzbekistan
Irrigated croplands in Central Asia are highly prone to land degradation due to their environmentally fragile physical settings and intensive agricultural practices. This study: (i) assesses the state of croplands in irrigated areas in northern Uzbekistan, based on the time series of MODIS-NDVI imagery; (ii) analyzes relationships between the identified trend of cropland degradation and soil quality, terrain characteristics, population density, a…
