Special Issue Information

Dear Colleagues,

Drlyand ecosystems always suffer from severe drought, erosion, soil and water loss and land degradation, especially in the context of accelerated climatic change and human disturbances. Worldwide, drylands occupy over 41% of total terrestrial land area and a home of more than 3 billion people, which determine the health and sustainability of our human beings. However, a successful restoration of the degraded ecosystems in drylands faces more and more challenges. Due to less precipitation, high water use and evapotranspiration of dense artificial forests, and degraded land soils, the relations among water, soil and forests are quite complex and need more innovative studies. Only when soil–forest–water are in good relations in such fragile water-restricted regions, can a successful land degradation neutrality and ecosystem sustainability be achieved.

This Special Issue is mainly trying to provide a valuable forum for discussing the new challenges of water, soil and forest management in dryland ecosystems. Land degradation can be reversed by reducing water erosion, increasing vegetation diversity and reserving soil water through adjusting plant density as well as their structures. In the meantime, it is also very important to reduce vegetation mortality through land preparation measures and terracing engineering in water-stressed hillslopes. Therefore, how to take solid and comprehensive measures to reduce erosion and mitigate water stress, improving the local site standards for forests, is the key scientific target of our Special Issue. Additionally, we do believe this topic is closely in keeping with the major scope of Land.

Short communications, research articles, review articles and perspectives are all welcome.

Topics with the followings but not limited:

  • Forest, water, human and soil nexus;
  • Water erosion control and assessment;
  • Land degradation and neutrality measures;
  • Climate change and forest management;
  • Plant and soil;
  • Forest thinning and ecohydrological response;
  • Soil and water conservation;
  • Drought, flooding and forest;
  • Land preparation and terracing.

Accurate estimation of evapotranspiration (ET) is vital for water resource development, planning and management, particularly in the present global warming context. A large number of empirical ET models have been developed for estimating ET. The main limitations of this method are that it requires several meteorological variables and an extensive data span to comprehend the ET pattern accurately, which is not available in most developing countries. The efficiency of 30 empirical ET models has been evaluated in this study to rank them for Pakistan to facilitate the selection of suitable models according to data availability. Princeton Global Meteorological Forcing daily climate data with a 0.25° × 0.25° resolution for 1948–2016 were utilized. The ET estimated using Penman–Monteith (PM) was considered as the reference. Multi-criteria group decision making (MCGDM) was used to rank the models for Pakistan. The results showed the temperature-based Hamon as the best model for most of Pakistan, followed by Hargreaves–Samani and Penman models. Hamon also showed the best performance in terms of different statistical metrics used in the study with a mean bias (PBias) of −50.2%, mean error (ME) of −1.62 mm and correlation coefficient (R2) of 0.65. Ivan showed the best performance among the humidity-based models, Irmak-RS and Ritch among the radiation-based models and Penman among the mass transfer-based models. Northern Pakistan was the most heterogeneous region in the relative performance of different ET models. Full article
