Summary The European honey bee, Apis mellifera, is the most economically valuable pollinator of agricultural crops worldwide. Bees are also crucial in maintaining biodiversity by pollinating numerous plant species whose fertilisation requires an obligatory pollinator. Apis mellifera is a species that has shown great adaptive potential, as it is found almost everywhere in the world and in highly diverse climates. In a context of climate change, the variability of the honey bee’s lifehistory traits as regards temperature and the environment shows that the species possesses such plasticity and genetic variability that this could give rise to the selection of development cycles suited to new environmental conditions. Although we do not know the precise impact of potential environmental changes on honey bees as a result of climate change, there is a large body of data at our disposal indicating that environmental changes have a direct influence on honey bee development. In this article, the authors examine the potential impact of climate change on honey bee behaviour, physiology and distribution, as well as on the evolution of the honey bee’s interaction with diseases. Conservation measures will be needed to prevent the loss of this rich genetic diversity of honey

Impact and Adaptation to Climate Change in Bangladesh

...Assessment Report of IPCC, South Asia is the most vulnerable region of the world to climate change impacts (McCarthy et al., 2001). The international community also recognizes that Bangladesh ranks high in the list of most vulnerable countries on earth. Bangladesh’s high vulnerability to climate change is due to a number of hydro-geological and socio-economic factors that include: its geographical location in South Asia; its flat deltaic topography with very low elevation; its extreme climate variability that is governed by monsoon and which results in acute water distribution over space and time; its high population density and poverty incidence; and its majority of population being dependent on crop agriculture which is highly influenced by climate variability and change. Despite the recent strides towards achieving sustainable development, Bangladesh’s potential to sustain its development is faced with significant challenges posed by climate change (Ahmed and Haque, 2002). It is therefore of utmost importance to understand its vulnerability in terms of population and sectors at risk and its potential for adaptation to climate change. Increased climate variability means additional threats to drought-prone environments and is considered a major crop production risk factor. The impact of climate variability and change on agricultural production is a global concern. However, the impact is particularly important in Bangladesh where agriculture is the largest sector of...

Jammu

...Chapter INTRODUCTION 1.1 Livelihood of the majority of the population of the Jammu & Kashmir State revolves around the agriculture and allied sectors. These sectors constitute the mainstay of the State’s economy and contribute nearly 50 per cent to GSDP. Over 70 per cent of the population, of more than 1.25 crores depends, directly or indirectly, on agriculture and its allied sectors. The diversification in the physiographic features and agro-climatic variation at macro- and micro-level, involving cold arid, temperate, intermediate and sub-tropical zones, within a small geographical area of 2.22 lakh sq. km indicates the inherent agricultural potential of the State. The net sown area (NSA) of 7.35 lakh ha (2009-10) is 35 per cent of the reported area as against the national average of 46 per cent. About 70 per cent of the net sown area is under the food crops. The average size of holding is very small (0.545 ha/holding) as compared to 1.66 ha at the national level with more than 93% of owners of these farm holdings subsisting on agriculture and allied activities. 1.2 Over the years, agriculturists and farmers have adopted several area- specific and time-specific cultivation practices to meet the requirement of their staple food crops. Rice, maize, wheat, pulses, fodder, oilseeds, potato and barley are the main crops of the State. There is currently a shift towards cultivating lowvolume high-value cash crops, such as, flowers, vegetables, quality seeds, aromatic & medicinal plants...

ECONOMIC VALUATION OF THE MANGROVE ECOSYSTEM ALONG THE KARACHI COASTAL AREAS Samina Khalil Applied Economics Research Institute, Karachi ABSTRACT The mangroves of the Indus River Delta in the Karachi, Pakistan coastal areas provide a wealth of goods and services to people who live and work among them. However, these products are not sold in established markets, so their economic importance goes unrecognized. As a result, the expansion of regional industry, agriculture, and population are permitted to threaten the sustainability of the mangrove ecosystems. This study describes the broad array of goods and services provided by the mangroves, and uses market data to estimate the economic value of a few of them. It then argues for the importance of more thorough ...

Agriculture (Pakistan Economic Survey)

... Agriculture is central to economic growth and development in Pakistan. Being the dominant sector it contributes 21.4 percent to GDP, employs 45 percent of the country’s labour force and contributes in the growth of other sectors of the economy. The healthy expansion in agriculture stimulates domestic demand for industrial goods and other services and supplying raw material to agro-based industry notably cotton textile industry which is the largest subsector of manufacturing sector. The government under paradigm of the new growth strategy envisioned to enhance growth in agriculture sector by facilitating agriculture productivity sustainable environment, increasing competitiveness in agriculture marketing and trade by providing friendly climate for more investment in the sector. However, draft tenth 5 years plan also envisages improving the productivity, profitability competitiveness and environmental sustainability of agriculture. Overall agriculture development strategy revolves to foster private sector-led development with public sector providing enabling environment through policy interventions and play capacity building role to improve agriculture related practices. The emphasis is on improving productivity and moving from subsistence to market oriented farming in the country to meet the domestic demand and surplus for export. The objective is to exploit potentials of our agriculture sector and use it as engine for economic growth and food security for the country. Consequent...
