Abstract Desertification threatens land integrity, social stability, and sustainable global economic development. Between 1982 2015, 6% of the world's drylands experienced desertification because unsustainable use practices exacerbated by anthropogenic climate change. Despite initiating several regional projects to control actively, United Nations Convention Combat (UNCCD) failed achieve its restoration goals. Therefore, this paper thoroughly examines primary factors contributing desertification, identifies obstacles impeding efforts, presents effective solutions combat pressing issue. Poor policy awareness about institutional gaps, cultural barriers, limited access credit modern technologies, lack standardization, inconsistent estimates extent were main constraints hindering efforts. However, implementing crucial approaches could effectively address challenge desertification. The capacity building, education, training should be more comprehensive for local communities, but managers, government officials, development planners part this. Local indigenous knowledge integrated with scientific get a better harvest against Sustainable management enhance soil productivity advanced technology (remote sensing, digital maps, machine learning data mining) help standardize procedures accurately assess Different can stabilize wind water erosion, such as bio‐cementing biocrust formation. Converting degraded areas into green spaces create 10 million jobs foster economy in developing countries. Finally, aspirant targets goals (SDGs), it is imperative carry out research on utilizing sound investing institutes next generation researchers.

Leaf Area Index (LAI) is one of the key parameters for characterizing leaf density, vegetation growth status, and canopy structure. Rapid, objective, accurate acquisition forest LAI great significance studying ecosystems forestry production. This study focuses on core issue accurately segmenting elements from background in hemispherical photography used measurement, with a particular focus meeting real-time requirements embedded platforms. The differences grayscale values frequency characteristics between regions, trunk sky regions images were leveraged to decompose, process, reconstruct such using 9/7 wavelet-based transformation method, achieving efficient precise segmentation regions. Effectively addresses overestimation caused by traditional threshold-based methods. Through extraction gap fraction, rapid measurement was enabled. Comparative experimental results showed that proposed inversion method exhibited high correlation LAI-2200C (r = 0.847, RMSE 0.431), fully verifying its accuracy across different ecological environments. provides strong support development portable, high-precision devices holds practical application value broad prospects.
