The natural ecological lands, such as forest land, grassland, wetland, etc., constitute the most important factor for maintaining and preserving the earth’s ecosystem, which must be well concerned in the regional function-oriented planning for the sustainability of human economic development. We analyzed and evaluated the change of natural ecological land in the function-oriented planning regions where we applied the major function-oriented zones introduced as a new concept in China. Using the land-use data from 2009 to 2018 that were produced by the National Land Use Survey, we re-classified natural ecological land types into the forest, grassland, wetland, and bare land, and then addressed the changes of natural ecological land types from 2009 to 2018 in the major function-oriented zones. As a result, the area of natural ecological lands generally tended to decrease from 2009 to 2018, while the decreasing trend of natural ecological land areas was controlled after 2015 with the implementation of governmental policies for environment protection and eco-logical projects. Especially, the decrease of forest land area significantly tended to be zero in 2018 in optimal development zones. The decreased areas of natural ecological lands were mostly converted from artificial land from 2008 to 2019. On the other side, the forest lands mostly changed from cropland and grassland in key development zones, agricultural production zones, and key ecological function zones, due to the fact that grassland conversed in afforestation during this period. The evaluation of natural ecological land changes, which could be implemented by using the annual updates of national land-use data in China, is significant to support the government’s spatial regulation design, to reshape the planned regions, and make policies for environmental restoration and protection management.

Abstract Background The gradual conversion of rangelands into other land use types is one of the main challenges affecting the sustainable management of rangelands in Teltele. This study aimed to examine the changes, drivers, trends in land use and land cover (LULC), to determine the link between the Normalized Difference Vegetation Index (NDVI) and forage biomass and the associated impacts of forage biomass production dynamics on the Teltele rangelands in Southern Ethiopia. A Combination of remote sensing data, field interviews, discussion and observations data were used to examine the dynamics of LULC between 1992 and 2019 and forage biomass production. Results The result indicate that there is a marked increase in farm land (35.3%), bare land (13.8%) and shrub land (4.8%), while the reduction found in grass land (54.5%), wet land (69.3%) and forest land (10.5%). The larger change in land observed in both grassland and wetland part was observed during the period from 1995–2000 and 2015–2019, this is due to climate change impact (El-Niño) happened in Teltele rangeland during the year 1999 and 2016 respectively. The quantity of forage in different land use/cover types, grass land had the highest average amount of forage biomass of 2092.3 kg/ha, followed by wetland with 1231 kg/ha, forest land with 1191.3 kg/ha, shrub land with 180 kg/ha, agricultural land with 139.5 kg/ha and bare land with 58.1 kg/ha. Conclusions The significant linkage observed between NDVI and LULC change types (when a high NDVI value, the LULC changes also shows positive value or an increasing trend). In addition, NDVI value directly related to the greenness status of vegetation occurred on each LULC change types and its value directly linkage forage biomass production pattern with grassland land use types. 64.8% (grass land), 43.3% (agricultural land), 75.1% (forest land), 50.6% (shrub land), 80.5% (bare land) and 75.5% (wet land) more or higher dry biomass production in the wet season compared to the dry season.

Society's needs in forest resources are due primarily to protective functions, and secondly to water protection, sanitation and health functions. Forests perform this or that function depending on their location, the area of the territory on which the forests are located and the composition. The article considers the problems of rational use and protection of forest lands. It is determined that the negative impact on forest land is due to intensive use and negative dynamics of the ecological state, as a consequence of improper land use and the impressive scale of deforestation. Industrial production, radiation pollution as a result of the accident at the Chernobyl nuclear power plant are the causes of deforestation. It is noted that in accordance with the Constitutions of Ukraine, forests are objects of property rights of the Ukrainian people, but due to mass deforestation, citizens are gradually losing the right to use them. It is noted that the protection and protection of forestry lands in general and forests in particular should be provided in accordance with existing legislation through the implementation of a set of measures, both traditional and new. The use of forests should be carried out exclusively in the order of general and special use in accordance with Art. 66, 67 of the Forest Code of Ukraine. It is proposed to strengthen control over compliance with current legislation in the field of protection of forestry lands and forests and control over land use. Reforestation is carried out on the sites of the felled forest. As part of the implementation of the commitments to achieve zero levels of soil degradation, develop an effective action program to preserve the country's forest resources.

This paper attempts to disclose the law of land use variation in the Northeast China Tiger and Leopard National Park (NCTLNP), and provide theoretical basis for eco-environment protection of the national park in future. The data on land use variation in four phases (i.e., 1995, 2005, 2015, and 2018) were selected for analysis based on the geographical information system (GIS). The variation and transfer features of land use were quantified, with the aid of single land use dynamic degree, comprehensive land use dynamic degree, and land use transfer matrix. The results show that: (1) In 1995-2008, the main land types in the NCTLNP were forest, grassland, and cultivated land, which took up more than 90% of the total area; the grassland area increased, while the areas of cultivated land and forest declined; forest was the land use with the largest transfer-out area (523.59 km2), about 55.29% of the total transfer-out area in the study area; (2) In the sample period, NCTLNP witnessed significant transfers between land uses; the transfers mostly occurred between forest, grassland, and cultivated land; forest transfers were observed in every county and city; the transfer of forest to grassland mainly concentrated in Dongning City. The research results lay the basis for building up a stereo eco-environment monitoring network in the study area, and provide the research direction for eco-environment protection in the NCTLNP.

Abstract Land use and land cover (LULC) is among fundamental environmental and ecological factors for monitoring, resource management, police making, planning and facilitating the development of strategies to balance conservation, development pressures, and conflicting uses. This study aimed at analyzing LULC changes that have occurred during 1988–2018 and its prediction for 2040–2060 period in Coka watershed, southern Ethiopia. LULC changes were analyzed using geographic information system and predicted by CA-Markov model. Cultivated and rural settlement land, bare land, built up area and water body have increased at an annual rate of 23.1, 2.2, 0.8 and 1.1 ha/year but forest land, bushland and grassland have decreased at an annual rate of 14.4, 4.1 and 8.7 ha/year, respectively. It is projected that cultivated and rural settlement land, bare land, built up area and water body will expand but forest land, grassland and bushland will decrease. Expansion of agriculture and deforestation showed increasing trend on both previous and predicted LULC changes with upcoming expansion of bare land and eucalyptus tree plantation due to major driving factor of population growth. This study highlights the need for well integrated landscape planning, reliable predictions for future LULC and to reduce the deterioration of environment.

Abstract Background Land use and land cover changes in urbanized watersheds of developing countries like Ethiopia are underpinned by the complex interaction of different actors, driving forces, and the land itself. Land conversion due to residential development, economic growth, and transportation is identified as the most serious environmental pressure on urbanized landscapes of the world. It results in the degradation of natural vegetation and significant increases in impervious surfaces. The purpose of the study was to analyze spatio-teporal changes in land use and land cover in the Huluka watershed with implications to sustainable development in the watershed. Results Forest land, cultivated land, urban built-up, bush/shrub land, bare land, grassland, and water body were identified as the seven types of land use and land cover in the Huluka watershed. Forest land decreased by 59.3% at an average rate of 164.52 ha/year between 1979 and 2017. Bush/ shrub land decreased by 68.2% at an average rate of 318.71 ha/year between 1979 and 2017. Grassland decreased by 32.7% at an average rate of 228.65 ha/year between 1979 and 2017. Water body decreased by 5.1% at an average rate of 1.06 ha/year between 1979 and 2017. Urban built-up area increased by 351% at an average rate of 16.20 ha/year between 1979 and 2017. Cultivated land increased by 105.3% at an average rate of 692.76 ha/year between 1979 and 2017. Bare land increased by 41.9% at an average rate of 4.00 ha/year between 1979 and 2017. Infrastructural and agricultural expansion, increased demand for wood, local environmental and biophysical drivers, rapid human population growth, economic drivers, technological drivers, policy and institutional drivers, and local socio-cultural drivers were perceived by residents as drivers of land use and land cover changes. Increased flooding risk, increased soil erosion, increased sedimentation into water resources like lakes and rivers, decrease in soil fertility, loss of biodiversity, loss of springs, decrease in annual rainfall, and increase in heat during the dry season were perceived by residents as negative local effects of land use and land cover changes. Conclusions Changes in land use and land cover in the study water shade imply the need for integrating sustainable watershed planning and management into natural resources management strategies. In other words, practices of appropriate land use planning and management, family planning, participatory planning and management, appropriate environmental impact assessment (EIA), and proper planning and management of development projects and programmes are of paramount importance to promote sustainable development in the Huluka watershed and beyond.

Forestland has been a focus of urbanization research, yet the effect of urbanization on forest land change on an urban agglomeration scale still remains unclear. Screening and quantifying the main factors affecting forest land changes have practical significance for land planning and management. Considering the characteristics of the region and referring to related studies, 26 natural, social, and economic factors were screened in the Pearl River Delta (PRD), where land-use changes are intense. Geographically weighted regression and the relative importance were used to quantify the spatial heterogeneity of these main factors. There was still a large area of deforestation evident in the PRD with its afforestation area of 604.3 km2 (mainly converted from cropland) and a deforestation area of 1544.6 km2 (mainly converted from built-up land). The effects of socio-economic factors were the main factors for these forest land changes, especially the rural population and migration. Deforestation mainly occurs in urban growth boundaries, which will be the focus area for further land management. These main factors have the potential to provide a methodological contribution to land-use changes, and the results of this study can provide a solid theoretical basis for forest land management and urban planning (e.g., balancing expansion of built-up land and ecological protection that advances forest land protection and restoration).

It is investigated that today the potential of financial provision of balanced forest land use of the territory of Small Polissya of Ukraine is not used at a sufficient level. In the study the example of state forestries of Small Polissya of Ukraine proved the need to diversify the sources of financial support for the processes of modernization, reconstruction and technical re-equipment of fixed assets in forestry. Proposed and scientifically grounded theoretical approaches to the expansion and intensification of financial provision of state forestries of Small Polissya of Ukraine with balanced use of forest lands. The choice of forestry enterprises took into account the factor of their geographical location in the area of the Small Polissya of Ukraine, so that in further research it was possible to conduct a pan-Ukrainian analysis on a national and land scale.

The headwaters of the Blue Nile River in Ethiopia contain fragile mountain ecosystems and are highly susceptible to land degradation that impacts water quality and flow dynamics in a major transboundary river system. This study evaluates the status of land use/cover (LULC) change and key drivers of change over the past 31 years through a combination of satellite remote sensing and surveying of the local understanding of LULC patterns and drivers. Seven major LULC types (forest land, plantation forest, grazing land, agriculture land, bush and shrub land, bare land, and water bodies) from Landsat images of 1986, 1994, 2007, and 2017 were mapped. Agriculture and plantation forest land use/cover types increased by 21.4% and 368.8%, respectively, while other land use/cover types showed a decreasing trend: water body by 50.0%, bare land by 7.9%, grassland by 41.7%, forest by 28.9%, and bush and shrubland by 38.4%. Overall, 34.6% of the landscape experienced at least one LULC transition over the past 31 years, with 15.3% representing the net change and 19.3% representing the swap change. The percentage change in plantation forest land increased with an increasing altitude and slope gradient during the study period. The mapped LULC changes are consistent with the pressures reported by local residents. They are also consistent with root causes that include population growth, land tenure and common property rights, persistent poverty, weak enforcement of rules and low levels of extension services, a lack of public awareness, and poor infrastructure. Hence, the drivers for LULC should be controlled, and sustainable resources use is required; otherwise, these resources will soon be lost and will no longer be able to play their role in socioeconomic development and environmental sustainability.

The study was aimed to assess urban induced land use land cover changes in the upper Deme watershed. Three satellite images of 1986, 2002, and 2019 were analyzed by ArcGIS and processed by supervised classification. Land use land cover change in the watershed increased for settlement, bare land, and croplands in the period 1986-2019 by 56.6%, 53%, and 0.25%, respectively. However, the land use land cover change in the watershed decreased for a water body, forest, and grassland by 65%, 57.7%, and 7%, respectively. These enforced to change the work habit and social bases. Out of converted lands, during 1986-2002, 34.9%, 53%, 18%, 40.9%, and 10.6% of bare land, cropland, forest land, grassland, and water bodies, respectively, in the upper Deme watershed were changed into settlement areas. During 2002-2019, 30.7%, 36.8%, 26.9%, 66%, and 33.3% of bare land, cropland, forest land, grassland, and water bodies, respectively, were changed into settlement areas. This shows urbanization results in a different change in economic, social, land use land cover, and watershed management activities in the upper Deme watershed.
