The present study aims to use systematic conservation planning to analyse and review the national protected areas (PAs) network in Jordan. The analysis included the application of three modules: the environmental risk surface (ERS), the relative biodiversity index (RBI), and the application of Marxan. The methodology was based on using Marxan to achieve solutions for three scenarios for the PAs network. Marxan was applied to the input data, which included vegetation types, distribution of threatened mammals and plants, locations of currently established PAs and other types of designations.

The project aims to improve the productivity of degraded rangelands through efficient utilization of limited rainfall. Nearly 48% of farmers in the Muhareb community own flocks, with an average flock size of about 159 head. About 52% of farmers in Um Al Naám own flocks, with an average of 125 head; about 63% of farmers in Muhareb community own a small flock (average 28 head), or a medium flock size (30%, average 293 head), or a large flock (7%, average 751 head. However, about 72% of farmers in Um Al Naám own a small flock, with an average flock size of 36 head.

Water scarcity and land degradation are widespread problems that affect agricultural productivity, food security and environmental quality in several parts of the world, particularly in the dry areas. Sustainable management of soil and water is necessary to optimize the use of limited rainwater for crop production and to decrease soil erosion. One management option is utilizing rainfall more efficiently through water harvesting. In arid areas, different types of water harvesting techniques (WHT) are being developed by

The main objective of this study is to introduce the first consistent long term land cover database for Jordan. The Jordan National Land Cover Database (JNLCD) consists of four land cover maps for the years 1984, 1991, 1998, and 2014 that were developed at 30m resolution using a total of 11 Landsat TM/OLI satellite scenes. We primarily applied ISO DATA classification method and rule based method for refining misclassified classes. The overall accuracy achieved for the 1984 land cover map was 88% and for the 2014 land cover map was 93%.

Research on micro-catchment rainwater harvesting techniques by ICARDA and Jordanian
scientists has led to the establishment of semicircular bunds on contour ridges and furrows
(using GPS laser-guided Vallerani machine) and runoff strips in two communities of Jordan
Badia. As an outcome of this research, an effective micro-catchment laser-guided system was
identified for rainfall harvesting, which has led to improved water availability, increased
vegetative cover and improved soil health, and provided rural communities substantial sources

The Badia constitutes about 90% of the total land area of Jordan, which is 89 342 km2. Its average annual rainfall is < 200 mm. The area with annual rainfall of 100–200 mm is considered the promising rangeland for rehabilitation. The Badia (part of the rangeland) supplies the livestock sector with about 20% of forage needs, while all the other sources provide the sector with only about 5% of forage.

Widespread heat waves, floods, and droughts last year were a strong reminder of the threats posed by climate change. In the non-tropical dry areas where ICARDA works we are becoming accustomed to record high temperatures and increasing water scarcity year on year. Resilience and climate change adaptation are at the heart of ICARDA’s new Strategic Plan 2017-2026 – a bold and ambitious effort to harness cutting-edge science and deliver the tools and technologies that smallholder farmers need to maintain agricultural production and protect their livelihoods.

Rangelands are the mainstay of pastoral livelihoods worldwide. Within rangelands, there are landscape depressions or lowlands characterized by high production potentials with their unique edaphic and hydrologic properties. The purpose of this ongoing research is to evaluate the effect of grazing exclusion on the vegetation characteristics and plant community structure in the arid lowland pastoral ecosystems. Plots were randomly identified within two distinct lowlands in Majidya and Sabha, in the Jordanian Badia.

This publication is a baseline assessment reviewing the current knowledge of land degradation in the rangelands of Jordan - known as Badia - with a special focus on its causes. It includes a review of current legislation and on-going initiatives to combat land degradation, along with an analysis of the main constraints limiting their effectiveness.
