PARTICIPATORY FOREST MANAGEMENT IN ANDHRA PRADESH : A Review

This paper traces the recent emergence of the new participatory forest management regime in AP Joint Forest Management (JFM) and Community Forest Management (CFM). This paper is based on the existing literature on forest policies, the historical context (pre-colonial, colonial and post independent India), and impact studies. The paper considers the contemporary developments in India in shaping the forest policies in AP. At the same time it considers the significant role played by donors and civil society. The process and quality of implementation, and the impact of the programme on local communities and resources are also examined. AP ranks fifth in India in terms of geographical area (275,068 sq km), and third in terms of forestland (63,813 sq km or 6.38 mha (Million Hectares), which constitutes 23% of APs total land area. Some 65% of APs forest area is spread over 8 predominantly tribal districts in the northern part of the state. These tribal populations are particularly dependent on the forest for their livelihoods for forest product collection and cultivation on forestland. Historically the relationship between these tribals and the government agencies, particularly the Forest Department (FD), has been very poor, with numerous uprisings, including the Naxalite movement. Many of these lands are disputed due to inadequacies in the legal processes by which largely tribal lands were declared state forests. Legally podu has de jure status prior to 1980 Act. Post 1980 podu cultivation is illegal and considered as encroachment. De facto podu is considered as encroachment (prior to 1980) as there is no proper settlement, conceptually typical podu practice is seen only in a few pockets in the state, especially in Vishakhapatnam. In 1956, on the formation of AP from Telangana and parts of the Madras Presidency, the pre-existing forest management regimes from the two distinct areas were harmonised by the Law Commission, leading to the AP Forest Act, 1967. Initially the states FD continued with a policy of commercialisation and revenue generation. However, with a growing crisis of forest degradation participatory approaches were introduced. The Government Order (GO) for JFM in AP was issued in 1992, although implementation didnt start until 1994. JFM has built on the roles played by both local forest *Centre for Economic and Social Studies, Hyderabad, India. +Overseas Development Group, University of East Anglia, Norwich, UK. users and the FD staff. Funding to the FD to promote JFM has come from both the World Bank (WB) and from centrally funded schemes, such as the Employment Assurance Scheme (EAS). Formation of Vana Samrakshana Samithies (VSS) began slowly after the GO, although by 2004 the official number stands at 7,245 VSS, managing 1,886,764 ha, (or over 29% of state forest land) and involving 611,095 families. The largest numbers of VSS are concentrated in the tribal areas of Adilabad, Visakhapatnam, and Khammam. The pattern of implementation and the outcomes is extremely complex, partly because of the wide variety of local conditions, ethnic and caste composition and local livelihood uses of forestland. The limited devolution of power which has occurred through VSS formation have however certainly been popular in many areas, because they have given local people endorsement to protect their local forest resources, upon which they depend for their livelihoods. Some employment opportunities have also been provided and some shares of revenues from forest product marketing are promised. Evidence suggests that the VSS have been successful in many areas in terms of regenerating degraded forests between 1993 and 1999. However there have been many criticisms of the JFM programme so far, most fundamentally focussing on the issues of power and land tenure. Because the FD has held almost complete discretionary power over the scheme and its implementation, the JFM process has inevitably reflected their objectives. Whilst many foresters have espoused very progressive ideas and concepts, in practice the implementation of the scheme has often furthered forest management strategy according to silvicultural norms, rather than local livelihood-oriented practices. In the context of a fundamental power asymmetry between the FD and the VSS., there has been little empowerment of local communities to take their own decisions with respect to forest management. This is most obviously seen in forest management plans. Whilst local people would like to see livelihood oriented forest management regime (ie. regular product flows, shorter term rotations, multiple product mixes) the FD has tended to prioritise its conventional forest management practices, often involving long rotation timber stands. The micro-plans commonly fit within wider divisional working plans. Livelihoods security could be increased if the forest resource were under a management plan, which actually prioritised local needs and opportunities. Institutional sustainability is a major problem in AP with many VSS becoming defunct due to conflict, lack of interest, or lack of funds. Where participation has been based on substantial funding flows, when the funds stop the motivation to participate reduces drastically. The institutional linkage between the VSS and the panchayat raj institutions has not been developed, which could ensure not only long-term sustainability, but also empowerment and legal independence of the local institutions. Non-Government Organisations (NGOs) have been largely excluded from the implementation of JFM, despite the fact they have played a major role in formulating the PFM policies at the state level.Forest Management, Andhra Pradesh

Revealing the role of electrons and phonons in the ultrafast recovery of charge density wave correlations in 1TT-TiSe2_2

Using time- and angle-resolved photoemission spectroscopy with selective near- and mid-infrared photon excitations, we investigate the femtosecond dynamics of the charge density wave (CDW) phase in 1$T$-TiSe$_2$, as well as the dynamics of CDW fluctuations at 240 K. In the CDW phase, we observe the coherent oscillation of the CDW amplitude mode. At 240 K, we single out an ultrafast component in the recovery of the CDW correlations, which we explain as the manifestation of electron-hole correlations. Our momentum-resolved study of femtosecond electron dynamics supports a mechanism for the CDW phase resulting from the cooperation between the interband Coulomb interaction, the mechanism of excitonic insulator phase formation, and electron-phonon coupling.Comment: 9 pages, 6 figure

Tracking primary thermalization events in graphene with photoemission at extreme timescales

Direct and inverse Auger scattering are amongst the primary processes that mediate the thermalization of hot carriers in semiconductors. These two processes involve the annihilation or generation of an electron-hole pair by exchanging energy with a third carrier, which is either accelerated or decelerated. Inverse Auger scattering is generally suppressed, as the decelerated carriers must have excess energies higher than the band gap itself. In graphene, which is gapless, inverse Auger scattering is instead predicted to be dominant at the earliest time delays. Here, $<8$ femtosecond extreme-ultraviolet pulses are used to detect this imbalance, tracking both the number of excited electrons and their kinetic energy with time- and angle-resolved photoemission spectroscopy. Over a time window of approximately 25 fs after absorption of the pump pulse, we observe an increase in conduction band carrier density and a simultaneous decrease of the average carrier kinetic energy, revealing that relaxation is in fact dominated by inverse Auger scattering. Measurements of carrier scattering at extreme timescales by photoemission will serve as a guide to ultrafast control of electronic properties in solids for PetaHertz electronics.Comment: 16 pages, 8 figure

Momentum resolved spin dynamics of bulk and surface excited states in the topological insulator Bi2Se3\mathrm{Bi_{2}Se_{3}}

The prospective of optically inducing a spin polarized current for spintronic devices has generated a vast interest in the out-of-equilibrium electronic and spin structure of topological insulators (TIs). In this Letter we prove that only by measuring the spin intensity signal over several order of magnitude in spin, time and angle resolved photoemission spectroscopy (STAR-PES) experiments is it possible to comprehensively describe the optically excited electronic states in TIs materials. The experiments performed on $\mathrm{Bi_{2}Se_{3}}$ reveal the existence of a Surface-Resonance-State in the 2nd bulk band gap interpreted on the basis of fully relativistic ab-initio spin resolved photoemission calculations. Remarkably, the spin dependent relaxation of the hot carriers is well reproduced by a spin dynamics model considering two non-interacting electronic systems, derived from the excited surface and bulk states, with different electronic temperatures.Comment: 5 pages and 4 figure

Probing the structure and dynamics of molecular clusters using rotational wavepackets

The chemical and physical properties of molecular clusters can heavily depend on their size, which makes them very attractive for the design of new materials with tailored properties. Deriving the structure and dynamics of clusters is therefore of major interest in science. Weakly bound clusters can be studied using conventional spectroscopic techniques, but the number of lines observed is often too small for a comprehensive structural analysis. Impulsive alignment generates rotational wavepackets, which provides simultaneous information on structure and dynamics, as has been demonstrated successfully for isolated molecules. Here, we apply this technique for the firsttime to clusters comprising of a molecule and a single helium atom. By forcing the population of high rotational levels in intense laser fields we demonstrate the generation of rich rotational line spectra for this system, establishing the highly delocalised structure and the coherence of rotational wavepacket propagation. Our findings enable studies of clusters of different sizes and complexity as well as incipient superfluidity effects using wavepacket methods.Comment: 5 pages, 6 figure

Evidence of reduced surface electron-phonon scattering in the conduction band of Bi_{2}Se_{3} by non-equilibrium ARPES

The nature of the Dirac quasiparticles in topological insulators calls for a direct investigation of the electron-phonon scattering at the \emph{surface}. By comparing time-resolved ARPES measurements of the TI Bi_{2}Se_{3} with different probing depths we show that the relaxation dynamics of the electronic temperature of the conduction band is much slower at the surface than in the bulk. This observation suggests that surface phonons are less effective in cooling the electron gas in the conduction band.Comment: 5 pages, 3 figure

Enhanced electron-phonon coupling in graphene with periodically distorted lattice

Electron-phonon coupling directly determines the stability of cooperative order in solids, including superconductivity, charge and spin density waves. Therefore, the ability to enhance or reduce electron-phonon coupling by optical driving may open up new possibilities to steer materials' functionalities, potentially at high speeds. Here we explore the response of bilayer graphene to dynamical modulation of the lattice, achieved by driving optically-active in-plane bond stretching vibrations with femtosecond mid-infrared pulses. The driven state is studied by two different ultrafast spectroscopic techniques. Firstly, TeraHertz time-domain spectroscopy reveals that the Drude scattering rate decreases upon driving. Secondly, the relaxation rate of hot quasi-particles, as measured by time- and angle-resolved photoemission spectroscopy, increases. These two independent observations are quantitatively consistent with one another and can be explained by a transient three-fold enhancement of the electron-phonon coupling constant. The findings reported here provide useful perspective for related experiments, which reported the enhancement of superconductivity in alkali-doped fullerites when a similar phonon mode was driven.Comment: 12 pages, 4 figure

Evolution of Ultracold, Neutral Plasmas

We present the first large-scale simulations of an ultracold, neutral plasma, produced by photoionization of laser-cooled xenon atoms, from creation to initial expansion, using classical molecular dynamics methods with open boundary conditions. We reproduce many of the experimental findings such as the trapping efficiency of electrons with increased ion number, a minimum electron temperature achieved on approach to the photoionization threshold, and recombination into Rydberg states of anomalously-low principal quantum number. In addition, many of these effects establish themselves very early in the plasma evolution ($\sim$ ns) before present experimental observations begin.Comment: 4 pages, 3 figures, submitted to PR
