Cultivated land is closely related to national food security, rural economic development and social stability. The cultivated land pollution and carbon emissions caused by chemical fertilizers, pesticides, film residues, etc., in the process of cultivated land utilization pose a serious threat to the cultivated land ecosystem in China. The comprehensive analysis on the cultivated land green utilization efficiency (GUECL), its influencing factors, and optimization direction provides a valuable basis for the green utilization of cultivated land.

Te Tiriti o Waitangi, signed between Māori rangatira (chiefs) and the British Crown in 1840 guaranteed to Māori the ‘full, exclusive and undisturbed possession of their lands’. In the decades that followed, Māori were systematically dispossessed of all but a fraction of their land through a variety of mechanisms, including raupatu (confiscation), the individualisation of title, excessive Crown purchasing and the compulsory acquisition of land for public works.

The use of land consolidation on customary lands has been limited, though land fragmentation persists. Land fragmentation on customary lands has two main causes—the nature of the customary land tenure system, and the somewhat linked agricultural system. Since attempts to increase food productivity on customary lands have involved fertilisation and mechanisation on the small and scattered farmlands, these approaches have fallen short of increasing food productivity.

In recent years, as a way to achieve higher agricultural output while reducing the negative impact of agricultural production on the environment, agricultural sustainable intensification has attracted worldwide attention. Under the framework of "connotation definition-measuring method-influencing factor-implementation path", this paper systematically sorts out the main research results in the field of agricultural sustainable intensification. The results show that: (1) The connotation of agricultural sustainable intensification has not been clearly defined.

The planting of sand-binding vegetation in the Qinghai Lake watershed at the northeastern edge of the Qinghai–Tibet Plateau began in 1980. For this paper, we took the desert on the eastern shore of Qinghai Lake as the study area. We analyzed a variety of aged Hippophae rhamnoides communities and aeolian activities, and we discuss the relationship between them. The main conclusions are as follows: (1) With an increasing number of binding years, the species composition became more abundant, natural vegetation began to recover, and biodiversity increased year by year.

Land-use history, not readily available
for most places, remains the weakest link in nearly all
studies of historic vegetation change, in Africa as well
as other places in the world. Notwithstanding,
communities hold a great wealth of knowledge on the
processes and events influencing change on the land
they occupy. The Lambwe Valley, southwestern Kenya,
has a multi-ethnic population of settlers from the early
1950s. These people have seen the transformation of
an initially forested area with diverse challenges to

This article is a contribution to the current debate on the concepts of land use planning and riparian zone
conservation. It discusses some of the major theoretical and conceptual issues that impact on the
practice of planning and conservation of riparian zones within the City of Nairobi. A conceptualization of
planning and conservation of riparian zone as well as the linkage between the two is discussed as the
paper critically seeks to identify some of the planning and conservation strategies in place, policy, legal

Soil indicators may be used for assessing both land
suitability for restoration and the effectiveness of restoration
strategies in restoring ecosystem functioning and services. In
this review paper, several soil indicators, which can be used
to assess the effectiveness of ecological restoration strategies
in dryland ecosystems at different spatial and temporal
scales, are discussed. The selected indicators represent the
different viewpoints of pedology, ecology, hydrology, and
land management. Two overall outcomes stem from the review.

Rural residential concentration was one of the important tasks of the “Three Concentrations” strategy implemented in the suburbs of Shanghai in the mid-1990s. The aims of this paper are to comprehensively evaluate the process, pattern and effects of residential concentration in the suburbs of Shanghai over the past 20 years, clarify the direction and focus of development, and propose suggestions for existing deficiencies.

Piping erosion is one form of water erosion that leads to significant changes in the landscape and environmental degradation. In the present study, we evaluated piping erosion modeling in the Zarandieh watershed of Markazi province in Iran based on random forest (RF), support vector machine (SVM), and Bayesian generalized linear models (Bayesian GLM) machine learning algorithms.

As 3D cadastres offer advantages in several areas by providing information with greater accuracy and a high level of detail, a diagnosis of the cadastral situation is required prior to the implementation of a 3D cadastral model. Therefore, this study focuses on diagnosing the urban cadastral situation in Ecuador based on an analysis of eight cantonal decentralized autonomous governments that were selected primarily for the availability of their cadastral information.

Sustainable forest management activities, such as future crop tree (FCT) release treatments, became part of the REDD+ strategy to avoid carbon emissions from forests. FCT release treatments are intended to achieve increased growth of FCTs by removing competitor trees. This initially leads to a reduction of the forest carbon pool and represents a carbon debt. We estimated that the time it takes for FCTs to offset the carbon debt through increased growth on experimental sites of 10 km² in Belize, Guyana, Suriname, and Trinidad and Tobago.
