The planted forest area in Vietnam increased from 3.0 to 4.4 million hectares in the period 2010–2020, but the loss of productivity from pests and diseases continues to be a problem. During this period, frequent and systematic plantation forest health surveys were conducted on 12 native and 4 exotic genera of trees as well as bamboo across eight forest geographic regions of Vietnam. Damage caused by insects and pathogens was quantified in the field and laboratory in Hanoi. The threats of greatest concern were from folivores (Antheraea frithi, Arthroschista hilaralis, Atteva fabriciella, Hieroglyphus tonkinensis, Lycaria westermanni,Krananda semihyalina, and Moduza procris), wood borers (Batocera lineolata, Euwallacea fornicatus, Tapinolachnus lacordairei, Xyleborus perforans, and Xystrocera festiva), sap-sucking insects (Aulacaspis tubercularis and Helopeltis theivora) and pathogens (Ceratocystis manginecans, Fusarium solani, and Phytophthora acaciivora). The number of new and emerging pests and pathogens increased over time from 2 in 2011 to 17 in 2020, as the damage became more widespread. To manage these pests and diseases, it is necessary to further invest in the selection and breeding of resistant genotypes, improve nursery hygiene and silvicultural operations, and adopt integrated pest management schemes. Consideration should be given to developing forest health monitoring protocols for forest reserves and other special-purpose forests.

The paper presents an overview of studies of the effects of inflation targeting on long-term economic growth. We analyze the potential channels of influence, as well as modern empirical studies that test performance of these channels. We compare the effects of different variants of inflation targeting (strict and mixed). Based on the analysis recommendations on the choice of optimal (in terms of stimulating long-term growth) regime of monetary policy in developed and developing economies are formulated.

The present study investigates diffusion and adoption of corruption and factors that influence the rate of adoption of corruption in Ghana. In the current study, the diffusion and adoption of corruption and the factors that influence the speed with which corruption spreads in society is examined within Ghana as a developing economy. Data from public sector workers in Ghana are used to conduct the study. Our findings based on the results from One Sample T-Test suggest that corruption is perceived to be high in Ghana and diffusion and adoption of corruption has witnessed appreciative increases. Social and institutional factors seem to have a larger influence on the rate of corruption adoption than other factors. These findings indicate the need for theoretical underpinning in policy formulation to face corruption by incorporating the relationship between the social values and institutional failure, as represented by the rate of corruption adoption in developing economies.

The natural conditions, climate change and socio-economic challenges related to the transformation from a socialistic society towards a market-driven system make the implementation of sustainable land management practices in Mongolia especially complicated. Forests play an important role in land management. In addition to providing resources and ecosystem functions, Mongolian forests protect against land degradation.We conducted a literature review of the status of forest management in Mongolia and lessons learned, with special consideration to halting deforestation and degradation. We grouped our review into seven challenges relevant to developing regionally adapted forest management systems that both safeguard forest health and consider socio-economic needs. In our review, we found that current forest management in Mongolia is not always sustainable, and that some practices lack scientific grounding. An overwhelming number of sources noticed a decrease in forest area and quality during the last decades, although afforestation initiatives are reported to have increased. We found that they have had, with few exceptions, only limited success. During our review, however, we found a number of case studies that presented or proposed promising approaches to (re-)establishing and managing forests. These studies are further supported by a body of literature that examines how forest administration, and local participation can be modified to better support sustainable forestry. Based on our review, we conclude that it is necessary to integrate capacity development and forest research into holistic initiatives. A special focus should be given to the linkages between vegetation cover and the hydrological regime.

Mobile money in Zimbabwe has extensively extended the frontiers of financial inclusion to reach millions who were earlier excluded within a relatively short space of time. The growing use of mobile phones in transferring money and making payments has significantly altered the countrys financial inclusion landscape as millions who had been hitherto excluded can now perform financial transactions in a relatively cheap, reliable and secure way. The FinScope results found out that 45% of the adult population use mobile money services. Of those using mobile money, 65% mentioned that is convenient, while 36% mentioned that it is cheap. Mobile money is accessible. These drivers are in the backdrop of few or no bank branches in rural communities as well as time and cost of accessing the bank branches. In Zimbabwe, mobile money is mostly used as a vehicle for remittances. While some people are enjoying mobile money services, it is important to mention that there are still people who are excluded from the formal financial system. The reasons why people do not use mobile money are mainly related to poverty issues. Mobile money remains a viable option to push the landscape of financial inclusion in Zimbabwe and other emerging markets where the formal financial system might not be strong.
