Special Issue Information

Dear Colleagues,

Land degradation usually indicates that the value of the biophysical environment is affected by the combination of human-induced process on the land and further affects the components of soil and the decline in land quality. Since the 20th century, it has been one of the most important global issues and has been put on the international agenda for the 21st century because of its close connection with food security. Land degradation adversely affects climate change and people’s livelihood. It is estimated that 1.5 billion people worldwide depend on degraded land for their livelihood. It is also evident that the people living on these degraded lands fully depend on natural resources for subsistence, food security, and income. However, the degradation of land has reduced these people’s productivity and has increased the working capacity required to fulfill their need.

The Special Issue aims to understand the major land degradation issues affecting terrestrial productivity and increasing CO2 emission under rising regional and/or global temperature. It includes possible measures that have been used to manage the impact of degradation on the rehabilitation of the land, the consequences of degradation with respect to the improvement in the productivity of the land, and the increase in the land’s carbon sink potential. Land management measures would help to understand specifically how carbon sinks are changing and what should be done to strengthen carbon sinks. This knowledge will help us achieve nature-based solutions to the Sustainable Development Goals. All these activities will also help us to enhance biodiversity and ecosystem-related services.

This journal explores the merits and demerits of the soils that are reducing the productivity of the land in all respects. As land degradation increases soil loss through erosion, runoff, reduce soil fertility, increasing emissions, and land degradation measurements, this issue will helps to reduce soil nutrients, enhance soil productivity and carbon sequestration, and overall enrich their productivity for the economy in future generations.

Land has published articles related to land use, land degradation, land rehabilitation, soil health, soil reclamation, biodiversity, and sustainable development of land through various management practices. Thus, the present topic of this Special Issue is related to issues of land degradation and its rehabilitation, which fit well with the themes of the journal.

Bhimal (Grewia oppositifolia) is the most important agroforestry tree species used for fodder, fuel and fiber in the Himalayan region. In the present study, G. oppositifolia-based traditional agroforestry systems were selected for the estimation of carbon stock and the production potential of barnyard millet (Echinochloa frumentacea) and finger millet (Eleusine coracana), with two elevational ranges, i.e., 1000–1400 and 1400–1800 m amsl, in Garhwal Himalaya, India. The results of the investigation showed a decline in the growth and yield attributes of both the millet crops under the G. oppositifolia-based agroforestry system at both elevations as compared to their respective control sites (sole crops). Among the elevations, the total number of tillers per plant (2.70 and 2.48), the number of active tillers per plant (2.18 and 2.25), panicle length (17.63 cm and 6.95 cm), 1000-seed weight (5.49 g and 4.33 g), grain yield (10.77 q ha−1 and 11.35 q ha−1), straw yield (37.43 q ha−1 and 30.15 q ha−1), biological yield (48.21 q ha−1 and 41.51 q ha−1) and the harvest index (22.53% and 27.78%) were recorded as higher in the lower elevation in both E. frumentacea and E. coracana, respectively, while plant population per m2 (18.64 and 25.26, respectively) was recorded as higher in the upper elevation. Plant height for E. frumentacea (180.40 cm) was also observed to be higher in the upper elevation, while for E. coracana (98.04 cm), it was recorded as higher in the lower elevation. Tree carbon stock was reported negatively with an increase in altitude. The maximum amount of sequestered carbon in the tree biomass for G. oppositifolia was 23.29 Mg ha−1 at the lower elevation and 18.09 Mg ha−1 at the upper elevation. Total carbon stock in the tree biomass was reported to be the highest (15.15 Mg ha−1) in the 10–20 cm diameter class, followed by 20–30 cm (6.99 Mg ha−1), >30 cm (2.75 Mg ha−1) and the lowest (2.32 Mg ha−1) in the <10 cm diameter class. The results show that the yield of E. frumentacea and E. coracana was not reduced so severely under the G. oppositifolia system; however, keeping in mind the other benefits of this multipurpose tree, i.e., carbon sequestration and socioecological relevance, farmers can get benefit from adopting these crops under G. oppositifolia-based agroforestry systems.
