Forest yield prediction under different climate change scenarios using data intelligent models in Pakistan / Previsão de produção florestal em diferentes cenários de mudanças climáticas usando modelos inteligentes de dados no Paquistão

Abstract This study aimed to develop and evaluate data driven models for prediction of forest yield under different climate change scenarios in the Gallies forest division of district Abbottabad, Pakistan. The Random Forest (RF) and Kernel Ridge Regression (KRR) models were developed and evaluated using yield data of two species (Blue pine and Silver fir) as an objective variable and climate data (temperature, humidity, rainfall and wind speed) as predictive variables. Prediction accuracy of both the models were assessed by means of root mean squared error (RMSE), mean absolute error (MAE), correlation coefficient (r), relative root mean squared error (RRMSE), Legates-McCabe's (LM), Willmott's index (WI) and Nash-Sutcliffe (NSE) metrics. Overall, the RF model outperformed the KRR model due to its higher accuracy in forecasting of forest yield. The study strongly recommends that RF model should be applied in other regions of the country for prediction of forest growth and yield, which may help in the management and future planning of forest productivity in Pakistan.

Resumo Este estudo teve como objetivo desenvolver e avaliar modelos baseados em dados para previsão da produção florestal em diferentes cenários de mudanças climáticas na divisão florestal Gallies do distrito de Abbottabad, Paquistão. Os modelos Random Forest (RF) e Kernel Ridge Regression (KRR) foram desenvolvidos e avaliados usando dados de produção de duas espécies (pinheiro-azul e abeto-prateado) como uma variável objetiva e dados climáticos (temperatura, umidade, precipitação e velocidade do vento) como preditivos variáveis. A precisão da previsão de ambos os modelos foi avaliada por meio de erro quadrático médio (RMSE), erro absoluto médio (MAE), coeficiente de correlação (r), erro quadrático médio relativo (RRMSE), Legates-McCabe's (LM), índice de Willmott (WI) e métricas Nash-Sutcliffe (NSE). No geral, o modelo RF superou o modelo KRR devido à sua maior precisão na previsão do rendimento florestal. O estudo recomenda fortemente que o modelo RF seja aplicado em outras regiões do país para previsão do crescimento e produtividade florestal, o que pode ajudar no manejo e planejamento futuro da produtividade florestal no Paquistão.

Impact of vehicular emissions on anatomical and morphological characteristics of vascular plants: A comparative study.

Abbottabad is a famous tourist destination due to its greenery and location. However, rapid increase in population and unplanned urbanization cause various environmental problems. Among different environmental stress, vehicular emission is the major issue for the survival and sustainability of plant species. This study aimed to investigate the effects of atmospheric pollution (caused by vehicular emission) on the anatomical, biochemical and morphological aspects of plant species present alongside the roads of Abbottabad, Pakistan. The plants were also collected from control sites (away from road-sites) for comparison. The results showed that various morphological characteristics of plant species including petiole length, vein-to-vein difference between leaves and length to breadth ratio of leaves were adversely affected by air pollution. The stomatal index varies in plant species because of variations in the numbers of epidermal cells. The air pollution tolerance index (APTI) of plant leaves from contaminated areas was reported to be higher as compared to control (non-contaminated) areas. Consequently, the findings from this study confirmed that plant species growing alongside of Abbottabad roads has greater tolerance than plant species growing in solitude areas away from road sites (control sites). Among different studied plants, Juglans regia, Morus nigra, Xanthium strumarium, Prunus armenica, Diospterus lotus and Populus ciliata have highest APTI and found to be more suitable for plantation in Abbottabad.

Identification and crop damage assessment of indian crested porcupine (Hystrix indica) in selected zones of Abbottabad, Pakistan / Avaliação de identificação e dano de cultura de porco-espinho indiano (Hystrix indica) em zonas selecionadas de Abbottabad, Paquistão

Indian crested porcupine is the largest rodent pest that damages a wide variety of crops, vegetables, and tree species which ultimately causes huge economic loss in Pakistan, which is an agricultural country. It prefers to live in hilly terrain but common in temperate and tropical forests, shrublands, and grasslands. This study focused on the identification and assessment of crops damaged along with the main precautionary measures used by the local farmers. The data was collected from twenty-four villages of two union councils i.e. Chamhad and Slahad of district Abbottabad. Two types of data (primary and secondary) were collected from the study area. Primary data was collected for identification and estimation calculation of total crop damaged through direct field observation by taking random quadrates in each village of the study area. The damage in the crop was assessed by randomly selecting a quadrate of 1x1 m2 for the wheat, pearl millet, and Sorghum fields. While 4x4 m2 quadrates were taken for maize and vegetables. At least three quadrate samples were taken from each field including one quadrate taken from the center of the field area. In union council Chamhad, damage to maize (11.31%) and wheat (0.73%) by the Indian crested porcupine while in union council Salhad, damage of maize (6.95%) and wheat (1.6%) was observed. In the entire study area, overall damage to maize crop (8.01%) and wheat (0.88%) was calculated. Based on information obtained from the farmers, the Indian porcupine inflicted damage to potato, tomato, cauliflower, chili pepper, turnip, radish, pea, and onion, etc. Secondary data obtained through a questionnaire survey to explore the human porcupine conflict and precautionary measures used by the farmers and landowners. Open and closeended questionnaires (159) highlighted the presence of Indian crested porcupine in the study area and 96% of the respondents have seen porcupine directly. Many types of precautionary measures were used by the farmers such as fencing, night stay, night firing, and dogs to decrease the crop damage, respondents (63.91%) use guns for hunting. however, due to the largely agricultural area and nocturnal behavior of Indian crested porcupine majority of the respondents (51.57%) did not use any precautionary measure. Biological control of Indian porcupine is recommended in the study area. Farmers should be encouraged and provide incentives and killing through current should be banned while proper hunting license should be issued to overcome overhunting. Scientific studies are required to control the reproduction of porcupine specifically in the more damaged areas.

O porco-espinho indiano é a maior praga de roedores que danifica uma grande variedade de culturas, vegetais e espécies de árvores, o que acaba por causar enormes perdas econômicas no Paquistão, que é um país agrícola. Prefere viver em terrenos montanhosos, mas comuns em florestas temperadas e tropicais, arbustos e pastagens. Este estudo concentrou-se na identificação e avaliação das lavouras danificadas, juntamente com as principais medidas de precaução utilizadas pelos agricultores locais. Os dados foram coletados de 24 aldeias de dois conselhos sindicais, ou seja, Chamhad e Slahad, do distrito de Abbottabad. Dois tipos de dados (primário e secundário) foram coletados da área de estudo. Foram coletados dados primários para identificação e cálculo de estimativa do total da cultura danificada por meio da observação direta do campo, tomando quadrantes aleatórios em cada aldeia da área de estudo. O dano na cultura foi avaliado pela seleção aleatória de um quadrante de 1x1 m2 para os campos de trigo, milheto pérola e sorgo, enquanto quadrantes de 4x4 m2 foram tomados para milho e legumes. Pelo menos três amostras de quadrante foram colhidas de cada campo, incluindo um quadrante retirado do centro da área do campo. No Conselho Sindical de Chamhad, houve danos ao milho (11,31%) e ao trigo (0,73%) pelo porco-espinho indiano, enquanto no Conselho Sindical de Salhad, danos ao milho (6,95%) e ao trigo (1,6%) foram observados. Em toda a área do estudo, danos gerais à cultura do milho (8,01%) e ao trigo (0,88%) foram calculados. Com base em informações obtidas dos agricultores, o porco-espinho indiano infligiu danos à batata, tomate, couve-flor, pimenta, nabo, rabanete, ervilha, cebola, etc. Dados secundários foram obtidos por meio de um questionário para explorar o conflito suíno humano e as medidas de precaução utilizadas pelos agricultores e proprietários de terras. Questionários abertos e fechados (159) destacaram a presença de porco-espinho indiano na área de estudo e 96% dos entrevistados viram o porco-espinho diretamente. Muitos tipos de medidas de precaução foram utilizados pelos agricultores, como esgrima, estadia noturna, fogo noturno e cães para diminuir os danos na lavoura. Dos entrevistados, 63,91% usaram armas para caçar. No entanto, devido à área ser em grande parte agrícola e ao comportamento noturno da maioria dos porcos-espinhos indianos, 51,57% não usaram nenhuma medida de precaução. O controle biológico do porco-espinho indiano é recomendado na área de estudo. Os agricultores devem ser encorajados e fornecer incentivos, e o uso da corrente para matar os animais deve ser banido, assim como deve ser emitida a licença de caça adequada para superar a caça excessiva. Estudos científicos são necessários para controlar a reprodução de porco-espinho, especificamente nas áreas mais danificadas.

No Conselho Sindical de Chamhad, houve danos ao milho (11,31%) e ao trigo (0,73%) pelo porco-espinho indiano, enquanto no Conselho Sindical de Salhad, danos ao milho (6,95%) e ao trigo (1,6%) foram observados. Em toda a área do estudo, danos gerais à cultura do milho (8,01%) e ao trigo (0,88%) foram calculados. Com base em informações obtidas dos agricultores, o porco-espinho indiano infligiu danos à batata, tomate, couve-flor, pimenta, nabo, rabanete, ervilha, cebola, etc. Dados secundários foram obtidos por meio de um questionário para explorar o conflito suíno humano e as medidas de precaução utilizadas pelos agricultores e proprietários de terras. Questionários abertos e fechados (159) destacaram a presença de porco-espinho indiano na área de estudo e 96% dos entrevistados viram o porco-espinho diretamente. Muitos tipos de medidas de precaução foram utilizados pelos agricultores, como esgrima, estadia noturna, fogo noturno e cães para diminuir os danos na lavoura. Dos entrevistados, 63,91% usaram armas para caçar. No entanto, devido à área ser em grande parte agrícola e ao comportamento noturno da maioria dos porcos-espinhos indianos, 51,57% não usaram nenhuma medida de precaução. O controle biológico do porco-espinho indiano é recomendado na área de estudo. Os agricultores devem ser encorajados e fornecer incentivos, e o uso da corrente para matar os animais deve ser banido, assim como deve ser emitida a licença de caça adequada para superar a caça excessiva. Estudos científicos são necessários para controlar a reprodução de porco-espinho, especificamente nas áreas mais danificadas.
