“…Similar to the results of previous studies, we find that the determination of the payment plan needs to consider the heterogeneity of farmers and the use of land, and diversified payment forms can bring more utility to farmers [59][60][61][62][63]. Different from existing studies, we find that mixed payment modes are not optimal in all situations.…”

Background: The distribution of farmers’ increment income is the key to the transfer of land use rights. This research aims to detect the optimal payment mode for the distribution of land increment income obtained by farmers in land rights transfer. Methods: The research relied on case analysis, mathematical analysis, and numerical simulation. Results: According to China’s existing payment modes for the increment income of rural collectively owned operating construction land (RCOCL), we summarized these payment modes into three: namely, lump-sum currency payment, a mixed payment of pension and lump-sum currency, and a mixed payment of dividend and lump-sum currency. If the land transfer price of RCOCL is lower than a specific value, the lump-sum currency payment will be optimal for farmers. Suppose the land transfer price is higher than this value. If the enterprise’s profit margin is higher than the pension rate of return, the mixed payment of dividend and lump-sum currency will be optimal; if not, the mixed payment of pension and lump-sum currency will be optimal. Conclusions: Differences in regions, enterprise attributes, and farmers’ characteristics will make the optimal proportion of pension or stock capital in land increment income (OPPSC) different. Generally, OPPSC is often between 40% and 60%.

“…The agroforestry systems observed in the research site are crucial for the livelihoods of local farmers, as they have both commercial and subsistence production values [36,37]. In addition to timber from tree species, field crops such as wheat also have good market prospects at local and international level, as these are widely used for consumption [38,39]. Although not intrinsically C dense compared to systems such as forests or intensively managed agroforestry systems and pastures, C storage in agricultural farms can be increased by 20.4 to 21.4 t C ha −1 globally [40,41] through the incorporation of long-living, deep-rooted trees [42,43].…”

The current study was conducted to estimate the carbon (C) storage status of agroforestry systems, via a non-destructive strategy. A total of 75 plots (0.405 ha each) were selected by adopting a lottery method of random sampling for C stock estimations for soil, trees and crops in the Mandi-Bahauddin district, Punjab, Pakistan. Results revealed that the existing number of trees in selected farm plots varied from 25 to 30 trees/ha. Total mean tree carbon stock ranged from 9.97 to 133 Mg C ha−1, between 5–10 km away from the brick kilns in the study area. The decreasing order in terms of carbon storage potential of trees was Eucalyptus camaldulensis > Syzygium cumin > Popolus ciliata > Acacia nilotica > Ziziphus manritiana > Citrus sinensis > Azadirachtta Indica > Delbergia sisso > Bambusa vulgaris > Melia azadarach > Morus alba. Average soil carbon pools ranged from 10.3–12.5 Mg C ha−1 in the study area. Meanwhile, maximum C stock for wheat (2.08 × 106 Mg C) and rice (1.97 × 106 Mg C) was recorded in the cultivated area of Tehsil Mandi-Bahauddin. The entire ecosystem of the study area had an estimated woody vegetation carbon stock of 68.5 Mg C ha−1 and a soil carbon stock of 10.7 Mg C ha−1. These results highlight that climate-smart agriculture has great potential to lock up more carbon and help in the reduction of CO2 emissions to the atmosphere, and can be further used in planning policies for executing tree planting agendas on cultivated lands and for planning future carbon sequestration ventures in Pakistan.

Brzina uklanjanja NO3 -iz kontaminiranih podzemnih voda ograničena je ukupnom površinom zemljišta raspoloživog za uzgoj topola kao i dužinom rotacije (Ranjan, 2021). Prema tome, remedijacija podzemne vode sa visokom kontaminacijom zahteva konverziju velike površine poljoprivrednog zemljišta i dugoročni vremenski okvir.…”

Although plants have a natural potential for removing various types of pollutants from nature, phytoremediation is a relatively new area of research and has a commercial application. By intensive application of nitrogen fertilisers and pesticides in agriculture, their excessive amounts reach the soil and accumulate or flow into deeper layers of soil and groundwater. So far, most soil remediation studies have been done with herbaceous plants, but they have not shown high efficiency. The paper gives an overview of the possibilities and advantages of using woody plants in the phytoremediation of soils contaminated with nitrates and pesticides. The choice of woody species that can be successfully applied is limited and the best results were obtained with poplars and willows. Unlike nitrates, which are easily absorbed by trees, pesticides are complex organic compounds and their remediation takes place through mechanisms such as rhizodegradation and phytodegradation. Poplar, as the most commonly used woody species for phytoremediation, has shown high efficiency in removing nitrates and pesticides, especially herbicides. Examples of successful soil and groundwater remediation can be found in the remediation of atrazine, alachlor, metribuzin, paraquat and others.
