Effects of acid deposition on terrestrial ecosystems and their rehabilitation strategies in China

South China has become the third largest region associated with acid deposition following Europe and North America, the area subject to damage by acid deposition increased from 1.75 million km 2 in 1985 to 2.8 million km 2 in 1993. Acid deposition has caused serious damage to ecosystem. Combined pollution of acid rain and SO 2 showed the obvious multiple effects on crops. Vegetable was more sensitive to acid deposition than foodstuff crops. Annual economic loss of crops due to acid deposition damage in eleven provinces of south China was 4.26 billion RMB Yuan. Acid deposition caused serious damage to forest. Annual economic loss of wood volume was about 1.8 billion RMB Yuan and forest ecological benefit loss 16.2 billion in eleven provinces of south China. Acid deposition in south China was typical “sulfuric acid type”. According to the thoughts of sustainable development, some strategies were brought forward as follows: (1) enhancing environmental management, specifying acid\|controlling region, controlling and abating the total emission amount of SO 2; (2) selecting practical energy technologies of clean coal, for example, cleansing and selecting coal, sulfur\|fixed\|type industrial briqutting, abating sulfur from waste gas and so on; (3) developing other energy sources to replace coal, including water electricity, atomic energy and the new energy such as solar energy, wind energy and so on; (4) in acid deposition region of south China, selecting acid\|resistant type of crop and tree to decrease agricultural losses, planting more green fertilizer crops, using organic fertilizers and liming, in order to improve buffer capacities of soil.

Assessment of Conflicts between Forestry and Agricultural Land Uses in Nigeria and Ghana

The study was conducted in four states of the Southwest geo-political zone in Nigeria and four regions in Ghana.. The results showed that the existing forest, agricultural and land use decree/policies in Nigeria and Ghana indicated lack of integration between Forestry and Agricultural land uses. The main conflicting areas were obsolete land use decree in Nigeria and lack of national land use policy in Ghana. The causes and effects of the conflicts had policy enunciation, stakeholders, and institutional and managerial dimensions. Some of the causes of the conflicts were lack of national land use policies for coherent and integrated forest and agricultural sectors; high population growth, de-reservation of forest reserves, unsustainable agricultural practices and technologies, land hunger, encroachment of forest reserves with cash crops and stakeholders＇ litany of demands and other diverse interests. Consequences of conflicts in the study locations included disharmony between forestry officials and farmers, antagonism between timber concenssionnaires and communities, wanton destruction of economic trees and seedlings, extinction of tree species, expansion of illegal farm lands and an attendant poverty. The logistic regression model for conflicts between forestry and agricultural land uses in Nigeria and Ghana indicated significant fit to the data judging from chi square value （df, 9） = 3174.1 that is significant at P 〈 0.05. The final loss of the model indicated a value of 92.47.

Ranking of Feijoa (FEIJOA Sellowiana) in Subtropical Humidified Zone of Adjara and Forest Ecosystem by Multiple-Factor Approach

It was elaborated a method of agro-ecosystem ranking for feijoa culture and forest ecosystem in one of regions of Western Georgia—Adjara subtropical humidified zone. On the basis of mineralogical and morphometric analysis (biometric parameters, beginning and end of growth, beginning of fruit ripening and mass ripening, frost resistance etc.) of feijoa culture (Feigoa selliowiana) and by multiple-factor approach we have evaluated culture’s rational disposition and optimal environment for development of land. The main accent was made on geomorphological (relief, inclination, exposition) and agro-climatic (sum of active temperatures, hydrothermal coefficient, temperature conditions, physical and chemical features of soil) factors. As a result of implemented zoning a landscape zone with agricultural resources potential and hypsometrical levels optimal for development of feijoa culture was revealed. During the research we also revealed corresponding agro-eco- system zone, compatible with feijoa zone, evaluation of quality of forest land and determination of ecosystem and its indicating character. For determination of compatibility of feijoa plants and distribution of forest ecosystem we have created a map of large-scale ecosystems and geo-information system. By Cartometric and geographic-informational analysis, it became possible to find information about types of forest ecosystems, areas occupied by them and their share in researched zone.

Consistency of Agricultural, Forestry and Mining Policies with Sustainable Forest Management in the East and South Regions of Cameroon

The eastern and southern regions of Cameroon, lower middle income country, need to increase their level of land use by the agricultural, forestry and mining sectors in order to develop. At the same time, Cameroon is committed to managing its forests sustainably to meet the needs of present and future generations. This study assesses the compatibility of agricultural, forestry and mining policies with sustainable forest management in the East and South forest regions. Five analytical criteria were used and the analysis was carried out through surveys of key informants in the private sector, public administrations and civil society. The study showed that from 2013 to 2018, the contributions of the agricultural, forestry and mining sectors to GDP grew by about 74%, 65% and 60%, respectively. Agricultural, forestry and mining policies have an average compatibility rate of 45% with sustainable forest management, of which 52% for the forestry sector, 43% for the agricultural sector and 40% for the mining sector. Nonetheless, there are 21 causes of incompatibility, including 1) the non-involvement of all relevant public administrations in policy-making, 2) the low efficiency of the control system of exploitation activities, and 3) the poor coordination of actions in the three sectors. It was proposed to a) improve the legal and regulatory framework of the three sectors of activity and b) develop land-use planning tools among other measures to align existing policies with sustainable forest management.

Role of arbuscular mycorrhizal fungi in sustainable crop production and forestry in Sri Lanka-A review

Mycorrhizae are symbiotic associations between a soil-borne fungus and plant root.Arbuscular mycorrhizal fungi(AMF)are the most common type of mycorrhizal associations occurring in plants.AMF can increase plant growth mainly by improving nutrient uptake and making plants resistant to several biotic and abiotic stresses.Thus,AMF could be referred to as an important biofertilizer for the crop production.However,in Sri Lankan context,seems the knowledge and use of AMF is limited,though there is a great potential of using AMF for sustainable crop production and forestry.This review provides an overview on the benefits of AMF for agriculture and forestry with the studies that have been carried out to attain them,in Sri Lanka.

Fuzzy Synthetic Evaluation of Wetland Soil Quality Degradation:A Case Study on the Sanjiang Plain,Northeast China

Wetland soil quality degradation caused by large-scale agricultural reclamation on the Sanjiang Plain of Northeast China has been widely reported. A relative soil quality evaluation (RSQE) model and a projection pursuit evaluation (PPE) model based on real-coded accelerating genetic algorithm were introduced to evaluate quality variations in top layers of the main wetland soils on the Sanjiang Plain in 1999 and 2003, respectively. As soil quality degradation boundaries were vague, this study established two fuzzy synthetic evaluation (FSE) models based on the original data and criteria used in the RSQE and PPE models. The outputs of the two FSE models were obtained by choosing two fuzzy composite operators M(∧, ∨) and M(·, ⊕). Statistical analysis showed that the results of the FSE, RSQE, and PPE models were correlated. In particular, outputs of the FSE model using M(·, ⊕) were significantly correlated with those of the RSQE model with r = 0.989 at P < 0.01. Compared with RSQE and PPE models, the FSE model may be more objective in showing soil quality variations and was closer to the natural situation, showing the feasibility and applicability of the FSE model in evaluating soil quality degradation. However, the choice of composite operator was of critical importance. The study of wetland soil quality degradation on the Sanjiang Plain was of scientific and practical significance for protection and management of soils and for sustainable development of agriculture in this area in the future.

Application of reaction nitrogen arc cladding TiCN/Fe composite coating on cutter of agricultural machinery

In order to solve the high-price and short-lifetime problems of the cutter of agricultural machinery,and improve the wear resistance of the cutter, the TiCN/Fe metal ceramic composite coating was prepared on the substrate of Q235 steel by reaction nitrogen arc cladding technique. The mixture powder of titanium and graphite was preplaced on the Q235 steel surface after intensive mixing by planetary ball mill and gluing with starch binder. The microstructure and phase of the coatings, interface behavior between coatings and the substrate were investigated by scanning electronic microscope and X-ray diffractometer. The micro-hardness distribution of the coating section was tested by micro-hardness tester. Friction coefficient and wear weight loss were measured by abrasion machine. Wearing surface morphology was investigated by scanning electronic microscope. The results show that an excellent bonding between the coatings and the Q235 steel substrate is ensured by the strong metallurgical interface and phase of the coatings. The coatings are mainly composed of TiCN. The highest micro- hardness of the coatings reaches 1 089 HV0. 2, while the micro-hardness of Q235 steel substrate is only about 286 HV0. 2. The anti-abrasive test results show that the wear resistance of the cladding coating is better than that of quenched and tempered 65 Mn steel which is often used as cutter of agricultural machinery. The field test results show that the TiCN/ Fe metal ceramic composite coating prepared by reaction nitrogen arc cladding is feasible to the manufacture and remanufacture of the cutter of agricultural machinery.
