“…Expenditures for development and agricultural productivity have driven economic growth in Pakistan over the past two decades as land used for crops has increased from around 20 million hectares (ha) to between 23 to 24 million ha over this time [59]. However, agricultural land in Pakistan has become degraded due to the intensification of agricultural production as cropland shifts to pasture or crops/pasture become abandoned [60,61]. Agricultural expansion has also come at the expense of forests in Pakistan, as land use has shifted from natural habitat to more intensive land uses such as human occupation and agriculture.…”

Rice–wheat crop rotations have high carbon fluxes. A 2-year field study in Punjab, Pakistan quantified impacts of different nutrient management on harvestable carbon biomass, crop-derived C, soil organic C sequestration (SCS), and decomposition. Treatments included different combinations of mineral fertilizer, animal manure (20 Mg ha−1), and incorporated crop residue in a split-plot design under conventional tillage (CT) and reduced tillage (RT). Combined use of mineral fertilizer and manure resulted in (1) 12.56% to 53.31% more harvestable C biomass compared to use of fertilizer and manure alone and (2) 18.27% to 60.72% more crop-derived C inputs relative to using only fertilizer or manure across both tillage practices. Combined fertilizer/manure treatments also significantly enhanced SCS relative to using fertilizer alone. Using only manure increased SCS by 63.25% compared with fertilizer alone across both tillage practices. The relationship between SCS and C inputs indicated high humification (14.50%) and decomposition rates (0.46 Mg ha−1 year−1) under CT compared to RT at 0–15 cm soil depth. At 15–30 cm soil depth, rates of humification (10.7%) and decomposition (0.06 Mg ha−1 year−1) were lower for CT compared to RT. Combined manure/fertilizer treatments could induce high C sequestration and harvestable C biomass with reduced decomposition in rice–wheat rotations.

“…It serves as a primary grazing area for livestock, especially small ruminants such as goats and sheep [19,43]. However, a substantial portion of this rangeland is undergoing degradation and has been converted to other land uses due to population pressure and natural processes, i.e., frequent droughts [44,45]. Indicators of rangeland degradation and its transformation into other land uses are discernible and exhibit region-specific distinctions.…”

Land use land cover (LULC) changes have emerged as a pivotal driver of environmental challenges in the Northwestern mountainous belts of Pakistan. These changes are increasingly recognized for their pervasive impacts on biodiversity and ecosystem services. The conversion of pastures and rangelands into other land uses is a key facet of LULC change, posing a substantial threat to the availability of animal feed sources. This study aims to evaluate LULC changes and investigate their consequences on animal feed sources in the Upper Kurram Valley, located in the Koh-e-Safid mountain of Northwestern Pakistan. The study employs a multidisciplinary methodological approach that incorporates remotely sensed data, focus group discussions, interviews, and field observations. The study findings uncover a notable decline in rangeland (26.6%) and forest cover (28.7%) over a span of more than three decades (1987–2019). The shrinkage of rangeland has spurred an increased reliance on crop residues and fodder crops. The free grazing practices have been replaced by stall-feeding and controlled grazing methods. This declining rangeland resources has negatively affected animal husbandry, and the average number of livestock per household decreased from 32 in 1980 to 3.7 in 2019. In essence, this transition has not only impacted animal feed sources but also reshaped the livelihoods of local communities closely connected to animal husbandry.

Various natural and anthropogenic activities such as climate change, urbanization and industrialization play a vital role in changing the land characteristics. These changes does not only affect the human lives and activities, but also results in tremendous decrease in agricultural productivity and arable land. Thus, the purpose of this study is to analyze the land degradation and desertification in Pakistan using satellite imageries data acquired from the Landsat 8 and 9. For the empirical analysis, various indices such as Normalized Difference Vegetation Index, Normalized Difference Bare Soil Index, Supervised classification and Land Surface Temperature are examined using Google earth engine cloud computing platform. The results showed that desertified and built-up-land are increasing, while degraded land, arable land, and vegetative land are decreasing in the study area. Also, results of land surface temperature analysis showed a rise in the temperature up to 3.060C as compared to previous two years. Moreover, estimated findings from regression analysis showed that Normalized Difference Vegetation Index, and Normalized Difference Bare Soil Index positively affects the Land Surface Temperature. The findings of study are important for government and concern stakeholders to take necessary measures to stop the conversion of productive green land into unproductive degraded and desertified land.
