Protected areas (PAs) play a key role in mitigating ecological crises. Currently, priority protected (PPAs) focus on biological conservation, and few studies have considered the connectivity between patches. Few formulated future conservation measures from two dimensions of security pattern (ESP) reserve effectiveness. To fill this gap, study use ESP to identify that meet objectives. We take Wuhan metropolitan area as research area. constructed framework for formulating development plans based areas. The complete method system, we focused construction evaluation index system landscape connectivity. Then, effectiveness PAs could be evaluated, PPAs identified. results showed there were five isolated among existing PAs. Moreover, total was 9328.91 km2, they had high value. Due low protection rate PPAs, are not main target PAs; thus, new According our plan, with different classes will achieve functions work.

Urban agriculture, the cultivation, processing and distribution of plants animals within urban or suburban boundaries, is becoming an increasingly relevant strategy to enhance food security for residents. With rapid urbanization in past decades, three forms agriculture have emerged China: small-scale, capital-intensive, tourism-type. Each form presents unique benefits challenges, their development has been largely shaped by local socio-economic context government policies. The are numerous including improvement community cohesion, promotion physical health, enhancement environmental sustainability, creation new economic opportunities. However, it also faces many challenges such as land availability, capital shortage, market access, governmental support. This review summarized its current limitations proposed strategies overcome these hurdles China based on successful examples Global North. Four specific recommendations were provided promote integration into cities, solutions resource use, support reactions, well planning regulations. Adoption expected result healthier cities a more robust agricultural system China.

The suitability evaluation of rural settlements is the core foundation planning and layout optimization. Settlements in a farming-pastoral ecotone are migrative, dynamic, diverse, thus their changes constantly. However, our limited understanding factors that drive this dynamic process affect humane hindered high-quality development human such areas. Here we selected ethnic minority border area Dalham Maomingan United Banner (DMUB) Northern China to evaluate its settlements. A data-driven machine learning maximum entropy (Maxent) method was applied settlement datasets DMUB years 1996, 2010, 2020, as well 13 influencing derived from optical images topographical ancillary data, demonstrating Maxent model can quantitatively measure contribution importance each factor variation over time.

In China, the invasion of Spartina alterniflora is an important driver for decrease mangrove area and ecological service functions related to this habitat. past few decades, S. clearing restoration projects have mainly focused on areas where it already changed but ignored potential distribution areas. This study suggested that implementation protection prior with threat could greatly improve efficiency save costs. Thus, using Maximum Entropy Modeling (MaxEnt), we estimated spatial both mangroves in considering current data, topographical, sediments, sea surface temperature bioclimatic variables. What’s more, identified calculated distributed each province. We aimed explore (i) key factors determining along coastline (ii) hotspots their competitive occurrence, including degradation areas, order support conservation. The model showed distance topography play roles alterniflora, while were more sensitive range annual temperature. Our results furthermore confirm has a wider (~10,585 km2) than (~9124 at China; predict provinces Zhangzhou, Quanzhou, Zhanjiang, Beihai Wenzhou as competition between alterniflora. propose priority should be given or plants those which are co-suitable these management measures conducted hinder invasions clear existing plants, firstly. provides guidance native species by preventing biological invasion.

Driven by the change in intense land use and cover (LULC) due to fast urbanization, urban flooding events have become most frequent influential hazards over last few decades. Accurately predicting possible flood-prone locations under dynamic fluctuations of LULC is crucial for sustainable development. However, there has been sparse studies on systematic integration changes into anticipate development scenarios coupled with vulnerability assessment. Therefore, this study proposed a robust powerful cascade modeling chain consisting Maximum Entropy, System Dynamics Patch-generating Land Use Simulation combination shared socio-economic pathways projecting temporal spatial associated vulnerability. Taking Guangdong Hong Kong Macao Greater Bay Area (GBA) as case study, results showed that increase was largely caused expansion construction land. Overall, substantial distinction within observed ranked order SSP126 < SSP245 SSP585. Under SSP585, areas high risk will be expected significantly, accounting 26% total areas, nearly half built-up are exposed 2050.

Excessive non-grain production of farmland (NGPF) seriously affects food security and hinders progress toward Sustainable Development Goal 2 (Zero Hunger). Understanding the spatial distribution influencing factors NGPF is essential for agricultural management. However, previous studies on identification have mainly relied high-cost methods (e.g., visual interpretation). Furthermore, common machine learning techniques difficulty in accurately identifying based solely spectral information, as not merely a natural phenomenon. Accurately at grid scale elucidating its emerged critical scientific challenges current literature. Therefore, aims this study are to develop grid-scale method that integrates multisource remote sensing data enhance precision provide more comprehensive understanding factors. To overcome these challenges, we combined images, natural/anthropogenic factors, maximum entropy model reveal scale. This combination can detailed information quantify integrated influences multiple from microscale perspective. In case Foshan, China, area under receiver operating characteristic curve 0.786, with results differing by only 1.74% statistical yearbook results, demonstrating reliability method. Additionally, total error our result lower than using information. Our enhances resolution effectively detects small fragmented farmlands. We identified elevation, farming radius, population density dominant affecting NGPF. These offer targeted strategies mitigate excessive The advantage lies independence negative samples. feature applicability other cases, particularly regions lacking high-resolution grain crop-related data.

ABSTRACT Illegal land occupation is a pervasive challenge in South Africa, particularly urban landscapes such as Cape Town. Despite numerous studies investigating its causes, spatial distribution, and impacts, there scarcity of research focused on predicting occurrence. This study addresses this gap by developing machine learning model to identify areas susceptible illegal invasion within the Town Metropole. A random forest (RF) regression was built utilizing samples prevalence pseudoabsence. total 1070 were collected (535 points per class), with 70% used for training 30% validation.
