Intensively practices rice-wheat (R-W) cropping system (RWCS) in South-Asia is suffering from many sustainability issues such as micronutrient deficiencies, labour scarcity, production cost, declining land, declining groundwater level and water productivity along with declining soil health. Climate change further complexes the things in one or other way. Therefore, the intervention of climate smart technologies is urgent for improving water productivity in an enormous water use RWCS of South-Asia. Although, farmers are confused regarding picking of suitable climate smart technology (CST) viz., laser land leveling, un-puddled direct-seeded rice (UPDSR), soil matric potential based irrigation, double zero tillage in wheat followed by rice, raised bed planting, short duration cultivars and correct transplantation time, for enhancing their livelihoods through increasing land and water productivity on one side and mitigating global warming consequences on other. Performance of these technologies is both site and situation specific, and care must be taken in practicing them. Most of them cutting down the drainage losses, which further reduces recharging of soil profile which is not required in water stressed regions while these might be termed as energy-saving technologies; otherwise used to withdraw water from the deeper soil depths. These CST are also useful for waterlogged regions. However, CST viz. correct transplantation time and short duration cultivars partition higher fraction of ET water (evapotranspiration) from E (evaporation) to T (transpiration) component which further favour higher grain yields and thus, higher water productivity. Therefore, it is crucial for introduction of CST for improving agricultural and water productivity in the era of climate change in an enormous water use RWCS of South-Asia.

Subject and purpose of work: The study attempts to examine the trade unfairness and transboundary bottlenecks between Bangladesh and India with a view to prosper a balanced trade and sustained water cooperation. Materials and methods: The study is based on secondary data and statistical information. Mixed research methods such as qualitative, quantitative and data visualization techniques are adopted in this study to assess the political economy of river basin management, loss and damage assessment and trade situation assessment. Results: Due to upstream intervention, the North-Western region of Bangladesh has lost 4254218 metric tons of rice production during 2006-2014 cropping years which value is $1036 million. During the same period, the trade deficit of Bangladesh stood at $5.58 billion with India due to the diverse tariff and non-tariff barriers which triggers tension between this close neighbor. Conclusions: The trade and water co-operation should be extended among the South Asian countries including India and Bangladesh without delay to obtain the maximum benefit and economic prosperity.

The fourteen new species of Rhaconotus Ruthe, 1854 from South Asia are described and illustrated: Rh. affinis sp. nov., Rh. chinensis sp. nov., Rh.fujianus sp. nov., Rh. hei sp. nov., Rh. heterotrichus sp. nov., Rh. intermedius sp. nov., Rh. ipodoryctoides sp. nov., Rh. iterabilis sp. nov., Rh. luteosetosus sp. nov., Rh. magnus sp. nov., Rh. oriens sp. nov., Rh. tergalis sp. nov., Rh. tianmushanus sp. nov., and Rh.yaoae sp. nov. The following species are recorded first time for the fauna of China: Rh. aciculatus Ruthe, Rh. menippus Nixon, Rh. nadezhdae (Tobias et Belokobylskij), and Rh. zarudnyi Belokobylskij. The key for determination of Chinese species of Rhaconotus is provided.

Forests are one the main natural factors that regulate and determine climate, weather patterns and amount of CO2 of an area. With rapid industrialization and rapid urbanization there is a significant increase in deforestation and as a consequence rise in global mean surface temperatures. Rapid and unchecked cut down of forest cover has resulted in some of the worst disasters during the last decades. This paper focuses on studying the role of deforestation, its influence on climate change phenomena and its consequences in Pakistan.
