    Global trends in pesticides: A looming threat and viable alternatives
    (Academic Press, 2020) Sharma, A; Shukla, A; Attri, K; Kumar, M; Kumar, P; Suttee, A; Singh, G; Barnwal, R.P; Singla, N.
    Pesticides are widely used chemical compounds in agriculture to destroy insects, pests and weeds. In modern era, they form an indispensable part of agricultural and health practices. Globally, nearly 3 billion kg of pesticides are used every year with a budget of ~40 billion USD. This extensive usage has increased the crop yield as well as led to significant reduction in harvest losses and thereby, enhanced food availability. On the other hand, indiscriminate usage of these chemicals has led to several environmental implications and caused adverse effects on human health. Epidemiological evidences have revealed the harmful effects of pesticides exposure on various organs including liver, brain, lungs and colon. Recent investigations have shown that pesticides can also lead to fatal consequences such as cancer among individuals. These chemicals enter ecosystem, thus hampering the sensitive environmental equilibrium through bio-accumulation. Due to their non-biodegradable nature, they can persist in nature for years and are regarded as potent biohazard. Worldwide, very few surveillance methods have been considered, which can bring awareness among the individuals, therefore the present review is an attempt to delineate consequences induced by various types of pesticide exposure on the environment. Further, the prospective of biopesticides use could facilitate the increase of crop production without compromising human health.- 2020 Elsevier Inc.

    Land acquisition in Punjab: Jeopardising livelihoods through inefficient implementation
    (Economic and Political Weekly, 2020) Kaur, S; Singh, G; Kaur, J; Singh, H.
    Analysing a case of development-induced displacement through a survey of land dispossession in Punjab reveals how displacement for development projects adversely affects farmers economically, socially and culturally. Fertile land acquired for a thermal power plant remains unused, depriving villagers of their livelihoods as well as the benefits that could have accrued had the project materialised. Large-scale land acquisition for the establishment of thermal power plants causes irreversible changes in the lives of local communities that are deprived of their source of livelihood by land acquisition and also gives rise to other social, economic, political and ecological changes. To avert the crisis resulting from the acquisition of agricultural land for developmental purposes, "long-term livelihood opportunities" for dispossessed farmers should be rebuilt, as compensation acts as wealth, and not income, for agrarian societies. - 2020 Economic and Political Weekly.
