Modeling and Forecasting of Agricultural Commodity Production under Changing Climatic Condition: A Review

India is a country with an agrarian economy in which majority of its population rely on agriculture directly as their source of livelihoof. Climate has a very significant role in agricultural production. It predominantly influences growth of the crop, development of the crop and eventually crop yield. Climate also significantly influences the outbreak of disease and pest; it affects the requirement of water by the crop. Possible changes in weather factors, like precipitation, temperature and CO2 concentration are expected to have a significant impact on crop growth. If farmers are able to predict the weather activities and are aware of the effect of these activities on crop production, then it will be beneficial to them as a feasible plan can be devised synchronizing the crop production activities as per changes in the climatic conditions. In view of tackling the aforementioned problem, this article describes various statistical techniques that can play a crucial role in forecasting production of agricultural commodities changing climatic conditions.

The Agricultural Settlement of the Arabah and the Political Ecology of Zionism

Agricultural settlement geared to capitalist commodity production and accompanied by massive ecological interventions has historically been central to the Zionist colonial project of creating a permanent Jewish presence in the “Land of Israel.” The hyperarid southern region known as the Central Arabah is an instructive edge-case: in the 1960s, after the expulsion of the bedouin population, cooperative settlements were established here and vegetables produced through “Hebrew self-labor,” with generous assistance from the state. In the 1990s the region was again transformed as the importation of migrant workers from Thailand enabled farmers to expand cultivation of bell peppers for global markets. But today ecological destruction, depletion of water resources, and global warming cast doubt over the viability of settlement in this climatically extreme region. I locate the settlements of the Arabah within the historical political ecology of the Zionist movement, arguing that their current fragility exposes the essential precarity of capitalist colonization.

The reality of the law of value

In the wake of Böhm-Bawerk’s criticism that Marx’s law of value runs contrary to empirical facts, Marxian economics has developed mainly in two different directions: one based on the simple commodity production and the other on the mathematical identity of value with prices of production (the transformation problem). The author agrees with neither, arguing that Marx intended to base the law of value on the production process of capital, as in Capital Volume 1, independently of Capital Volume 3. However, the notion of this process and the law of value have not been sufficiently explained in Volume 1. Marx presents the value of a commodity as socially necessary labour objectified in Chapter 1 on the commodity, and later applies this rule to capitalist commodity products in Chapter 7. Pointing out the defects of this method, this article relocates the presentation of the dual nature of labour to the Labour Process (Chapter 7, Section 1), and the proof of the substance of value or the law of value to the Valorization Process (Chapter 7, Section 2). The Labour Process plays a key role in Volume 1, but it contains a fatal flaw. Consequently, Section 2 ends up with insufficient explanation. By reconstructing the Labour Process and the Process of Creating Value and Surplus value, the author confirms the meaning and reality of the law of value in Chapter 7, Section 2.

Antinomies of space and nature or an open totality? Neil Smith and Henri Lefebvre on nature and society

The work of Henri Lefebvre has played a pivotal role in human geography in recent decades. At the same time, it has frequently been subject to partial and fragmented appropriations that isolate his insights on the production of space from his broader corpus, leading to confusion and misunderstanding regarding his handling of the dialectical relationships between space, time, society, and nature. In particular, Neil Smith's claim that Lefebvre's conceptualization of nature was both deficient and inconsistent with his dynamic conceptualization of space has tended to dominate geographical engagements with Lefebvre in this area. Following Smith, researchers generally reconstruct the production of space as an epiphenomenon of the production of nature. We critically assess and respond to Smith's criticisms of Lefebvre. Specifically, we contrast Lefebvre's material–dialectical approach to Smith's production-of-nature thesis. While Smith's thesis is helpful in understanding how capital attempts to subsume all of nature under commodity production, Lefebvre's dialectical conceptualization of nature–society as an oppositional unity points both to the impossibility of capital subsuming all of nature and the dangers that its attempts to do so pose to human civilization (even survival). Lefebvre's observations, regarding the growing rupture between natural processes and spatial dynamics, which he incorporates into his own elaboration of Karl Marx's theory of metabolic rift, make his work indispensable to the development of an ecospatial critique within geography and the social sciences more generally.

Broadening the Perspective of Zero-Deforestation Interventions in Peru by Incorporating Concepts from the Global Value Chain Literature

Global narratives around the links between deforestation and agricultural commodity production have led to the application of voluntary zero-deforestation agreements between companies, governments, and civil society. The continued tropical deforestation warrants a re-examination of this approach in order to customize its application for a particular location. Our paper contributes to this by exploring the spatial associations between deforestation and the production of cacao, coffee, and oil palm in the Amazon region in Peru. The geographical overlaps between deforestation, and the distribution of these commodity crops, indicate four types of spatial associations: (1) a high degree of deforestation and a high degree of commodity production (high-high); (2) a high degree of deforestation and a low degree of commodity production (high-low); (3) a low degree of deforestation and a high degree of commodity production (low-high); and (4) a low degree of deforestation and a low degree of commodity production (low-low). On the basis of these associations, we present four scenarios in which zero-deforestation supply chain interventions may operate in Peru and argue that broadening the perspective of such interventions by adopting a global value chain lens can improve the use of previously deforested lands, prevent unintended or future deforestation and, in turn, ensure that no forest area is left behind.

Anthropological Perspectives on Fair Trade

Fair trade is a trading partnership, based on dialogue, transparency, and respect, that seeks greater equity in international trade. It contributes to sustainable development by offering better trading conditions to, and securing the rights of, marginalized producers and workers. Minimum prices and social premiums linked to fair trade certifications, which require independent audit of the environmental, economic, and social conditions of commodity production and exchange, are integral to the system. Anthropological explorations of fair trade practices emphasize the cultural dimensions, socio-economic conditions, and political economy. Anthropological scholarship explores how experiences of fair trade are diversely influenced by gender; racial and ethnic identities; differences in wealth and resources, education, and geographic location; and political hierarchies and social institutions. The nuanced insights into fair trade impact produced through detailed, ethnographically driven anthropological research ultimately illustrate the limits of social movement-driven, rural-development alternatives and produce empirically informed, practical suggestions for how the current system could be improved. Anthropological expertise is appreciated within the fair trade assemblage, which encompasses development organizations, certification firms, importers, and retailers.
